Sub Zero

Chapter Text

Before you read, this is what you need to know to understand what's happening. All people take a test when they turn twelve to find where they lie on the sub-Dom scale. A ten is the most dominant and a one is the most submissive. Only subs in the Care System are ever assigned to a Dom who must have scored a nine or higher on their test. People do not know about werewolves; the fire still happened, Allison is still alive as is Laura but Derek is still the Alpha. The Pack consists of Derek, Laura, Cora, Peter, Lydia, Jackson, Danny, Ethan, Aiden, Erica, Boyd, Allison, Scott, Isaac, Kira, and Stiles. The mated pairs are Lydia and Jackson, Danny and Ethan, Isaac and Cora, Erica and Boyd, and Allison and Scott. Sheriff Stilinski and Claudia both died when Stiles was young, and he lives with Scott and Melissa but is still registered in the System. Stiles is sixteen which is the legal age, but subs are usually assigned at seventeen unless they tend to cause trouble. They stay with the Dom for two months in the hopes that it will change their behaviour. After the two months are over the sub can decide whether or not they want to stay with the Dom. Stiles is a Delta sub and has never told anyone because of the things he experienced being in the System. Deltas are discriminated against and seen by many as sexual objects only good for bearing Dom children. Stiles is a high school senior despite being sixteen because he was moved up a grade. He's also Pack-Mom. Okay, that's all you need to know, enjoy. -Addy

______________________________________

It had been quite a surprise when Derek received a letter in the mail informing him that he had been assigned a sub. He didn't know how to feel about it. His true mate was Stiles, he'd known it from the moment he met him a year ago. Of course, he didn't say anything. The teen was so young, and Derek's record of romantic partners wasn't great. They either died or were psychos.

When the existing Pack had met Stiles, their original impression had been he was annoying and stupid. While the first part was true, Stiles was anything but stupid. He was an absolute genius. He'd even been moved up a grade in school. He had never gotten anything less than a perfect score, and the Pack didn't need a calculator at all, the kid could do advanced calculus in his head. He was the most caring and kind person Derek had ever met. He would drop whatever he was doing if someone needed something. He really was like a mother when he wasn't acting like a fool.

The only issue was, he had no concern for his personal safety which is what had made them think he was an idiot. No rational person would do anything like the stuff he did. He didn't care what happened to himself as long as it helped other people. He was the pillar of martyrdom.

It was this that caused Derek to worry so much. No matter how much he had wanted to just tell Stiles the truth, he was scared something would happen to the boy. The rest of the Pack accepted him easily, but Derek had tried his hardest to make Stiles leave. It pained him to be so cruel, some of the things he said haunted him at night. He would remember the hurt expression on the teen's face and wouldn't be able to sleep from the amount of guilt he felt.

Laura always said Derek was the most stubborn person ever, but that changed once Stiles came around. He was pretty lenient with most things. If a friend asked him to do something, he would do it. Unlike any other sub he had ever encountered, if someone ordered Stiles to do something he didn't want to, then he wouldn't do it.

He'd never seen a sub resist a Dom's Voice. Only the strongest Doms had it, Derek being one of them. He had sworn never to use it against someone, but there were others who would take advantage of owned subs because they couldn't refuse an order given with the Voice.

Stiles proved it wrong though. The Hale Pack was having at a gathering that happens once a year where multiple packs come together. There was an Alpha named Jason who was well known by the others for using his Voice for the wrong purposes. It would work on lesser Alphas and Betas too but not to the extent of subs. He immediately approached Stiles, having heard stories of the rebellious sub. He wanted to make Stiles submit to him.

Stiles was standing by a table at the time talking to a female Beta when Jason cut into their conversation. The Beta was from his pack, and with a single look, she backed away. Derek and the others were discussing with Ben, an Alpha from a Michigan pack. Derek was only partially paying attention to what Ben was saying. He was too busy watching Stiles, anger growing silently. He wanted Stiles to submit to him and only him.

Jason said something, Derek was unable to make out the words, but he knew Jason had used the Voice. Around the two, others had stopped to watch. They were expecting Stiles to do what Jason had said but instead, Stiles cocked his head and pursed his lips.

The look of shock on everyone who had heard it was fantastic. Derek was sure his own face had the same look. Ben stopped talking; everything went silent as all attention in the large room turned towards Stiles and Jason who raised his Voice enough for them to hear it.

"I said, 'sit down boy'" he growled through gritted teeth, pointing to a chair nearby. Stiles gave a look but turned and walked to sit down in the seat. The room began to return to their lost conversations, but instead, a collective gasp filled the air.

Stiles had been told to sit down in the chair. Instead... he got up and stood on it.

He leaned forward, hands on his knees. He stared directly into Jason's eyes, a big no-no when dealing with Doms, and said, slowly, "I have one Alpha, and you are not him, Dickhead. Don't try to tell me what to do." He leaned back, crossing his arms and having his hip to the side. Typical Sassy Stiles.

Jason was fuming. He'd been embarrassed in front of not just his own pack but nearly twenty other packs. He launched at the teen before anyone could stop him but Stiles had been anticipating it. Using his slight frame, he was able to dodge out of the way, landing a well-placed kick on the way. With a knee to the chest and another kick across the face, Jason went down, gasping for breath, completely winded.

"Lesson here is; don't be an asshole," he said as he tugged on his shirt to straighten it before turning to the others who were frozen in shock and gave them a polite smile like nothing just happened and walked back to Derek and the rest of the Pack.

Derek had never been prouder of anyone in his entire life and he fantasized that maybe, someday when Stiles was older, he would willingly submit to him.

Stiles was by far the most interesting and intriguing of the Pack. He had somehow made it seem like he was an open book when if you really thought about it, no one knew anything about him. He knew everything about all of them though. The kid was like Sherlock Holmes he was so observant. He'd figured out all of them before they even said anything.

One time, when Scott had been delirious due to venom from a creature, he started telling Derek some things about Stiles. He said that he thought Stiles was being over-medicated. They were just giving him all of these anti-depressants and anti-anxieties instead of actually trying to help him.

Derek was going to ask him further, but Stiles had walked in to take care of him. It left Derek with all these unanswered questions in his head. Stiles always seemed so happy. His laugh was contagious and he could cheer anyone up with a few bad puns and some sarcasm mixed in.

He was the one they all went to when they needed to talk to someone. Derek still couldn't understand how Stiles had managed to get even him to open up. Derek told him everything. Kate had been an amazing girlfriend which is what made the betrayal even worse. He'd blamed himself for so long. What happened was his fault.

But then, Stiles pointed out something. Kate had set fire to the weakest part of the house. It was past a security gate that had a key code that contained the outside generator. Derek had never shown her that area nor had he given her the password. That meant she had already known it was there.

Stiles was a pro at manipulation. He was able to convince Chris to let him into Kate's old room. Of course, being as observant as he was, it didn't take long for him to find the hidden drawer that contained her journal. Inside was detailed how she would go about the fire and where to set it. The dates on it were well before the relationship with Derek had begun. She already knew the layout of the house. She would have done it regardless of Derek.

It felt like a physical weight had been lifted off of his chest. He still felt the loss of his family, but now he knew that it wasn't his fault and the guilt he'd kept inside for so long melted away. He felt free for the first time in a long time.

Derek had expected Stiles to open up to him in return. He'd waited and waited, and it never happened. He... did not expect the reaction he received when he tried to get Stiles to talk. He got defensive, turning against Derek the moment he asked a personal question. It was a bit of a shock.

Derek had seen Stiles upset before, but he'd never truly lost his cool until then. Derek thought he was a private person but Stiles was on a whole 'nother level.

He'd asked him why he was living with Scott. Stiles replied that he was in the System and had met Scott at school. A little while after Melissa met him, she filed for foster care.

Derek had seen from the first word he spoke, Stiles was uncomfortable. He knew he really shouldn't have pressed for more answers but he honestly didn't anticipate Stiles' reaction.

He asked why Stiles was in the System and the immediate change that happened in the boy's demeanour left him taken aback. Stiles' whole body tensed, his fists clenched at his sides and his eyes. God, his eyes. They darkened and Derek felt like they were burning straight through him.

"That's none of your business," Stiles said, voice taking on a dangerous tone. Unfortunately, the natural Alpha Dominant side of Derek comes out when faced with a challenge or hostility.

"I told you everything. You have to tell me something now," he said, flashing his eyes red. Apparently, that was the wrong thing to say.

"I DON'T HAVE TO DO SHIT!" he screamed, getting up in Derek's face. Derek instinctually growled and he stepped closer as well, leaning in crowding the teen. That just set Stiles off even more. "If I say it's none of your business, you back off and leave it," he spat, seething.

When the teen turned away, Derek grabbed his arm. Stiles whipped around and slapped him across the face, hard. Had it been a normal person, it may have even knocked them out but it certainly shocked the werewolf into letting go of the boy's wrist.

Stiles walked away, head bent low and trying to hide tears. That night, Derek went to his window to try to apologise only to be met with a line of mountain ash that burned his hand.

Stiles stopped talking to him when the Pack was all together and refused to be in a room with Derek alone. Eventually, the tension between the two began affecting the others. Stiles finally gave in and agreed to at least try and speak with Derek after Isaac begged him. Stiles never got angry with Isaac, never even raised his voice at the older boy.

Derek and Stiles were left in privacy and for the first minute, it was completely silent other than Stiles' rapidly beating heart and the sound of him tugging on the sleeve of his sweater.

Derek blurted out his apology. "I'm sorry. You didn't want to talk about it and I kept pushing and I'm sorry." He looked at Stiles, hoping the teen would see the sincerity in it and see the guilt he felt for upsetting him like that.

Stiles huffed a breath, glancing down at the ground before looking up at Derek and walking towards him. Confused was an understatement for what Derek felt when Stiles embraced him in a hug, resting his head against Derek's chest.

"Sorry, for bitch-slapping you like that," he chuckled. Derek hadn't realised he'd been holding his breath until he let out a relieved sigh and inhaled Stiles' scent. Strawberries and vanilla, cinnamon if he was angry. No matter what, he always smelled like the most delicious thing in the world.

He tried to come up with something to say, something to affirm that this issue was over. All he could think of was what Stiles and Scott said to each other whenever they got in a fight.

"We cool?" he asked. He heard Stiles snort quietly, "yeah, we're cool. I think our audience may want to come back in though," he said, walking sideways to press against the wall and sliding towards the door. Derek was utterly confused by this until Stiles ripped open the door and a wave of bodies came crashing down. Of course, the Pack had been listening in.

There was some groaning by the ones who were lying on the floor and sheepish grins from the others. Derek would have been angry at the eavesdropping had Stiles not suddenly been pushed back into his arms by a very happy Laura. To be honest, Derek really didn't want to let go. He wanted Stiles with him always.

That had happened a couple months ago, since then, whenever they were talking to each other, if one of them, either one, was getting uncomfortable, they would tell the other. Whichever of them was making them feel that way, they would back off. That never actually happened with Derek though. He never withheld anything from the teen. Stiles knew him better than anyone else.

Stiles had opened up a little as well. Just barely. But, it was still something. He said his mother died of an illness when he was young and less than a year later, his father, a sheriff in their little New York town, was killed while off-duty. Derek knew not to ask more into that and instead embraced him, seeing the tears he was trying to hold back.

Because of this newfound closeness with Stiles and the possibility that it may become something more, Derek debated whether or not to go to court and try and have the sub assigned to someone else. Stiles had said it was fine but, he was absolutely lying and didn't even try to hide it. The last thing Derek wanted, was to ruin this growing relationship they had.

He was waiting for the second letter to arrive that would contain the information and background of the sub. He had to have their name in order to file for re-placement.

Soon enough, he saw the envelope on his table but avoided it all day. He felt guilty. Assigned subs were troubled teens who needed a Dom to care for them and help them learn proper behaviour and he was denying one of them that opportunity. He got a text from Stiles late at night.

Red: Hey Dee?

You: yeah?

Red: You wouldn't have happened to have read your sub letter yet would you?

You: no why?

Red: You miiiiight want to do that right now.

Derek got himself a drink before opening the letter. He took a sip as he began to read it and nearly spit everywhere when he saw the name.

Mieczylsaw "Stiles" Stilinski

Chapter Text

Needless to say... Derek had absolutely no idea what to do. He thought it had to be a mistake, there was no way he would be assigned someone who he already knew. The Dom and sub were supposed to be strangers so the sub would learn how to behave when faced with someone they've never met before.

You: is this for real?

Red: Yeppo. I got my letter detailing who my new Dom would be. Imagine my surprise when I read your name. Your middle name starts with an 'S' what does it stand for?

Red: Samuel?

Red: Stanley?

Red: Sabrina?

You: can we focus on this rn?

Red: Sure.

Red: I still wanna know what the 'S' stands for.

You: first try was right

Red: Aw nice!

You: you got some name as well

Red: Not my idea, obviously. See why "Stiles" is so much easier?

Red: Mom was Polish.

Red: Decided it was a great idea to give her kid literally the most difficult name ever.

Red: Try spelling it to an old person on the phone when calling to see how much money is in your bank account.

Red: Takes half an hour to find out, I have $0.36

Red: I need another job.

Red: Like I have two already but the majority of the money goes to helping Scott and Melissa.

Red: Maybe I should be a stripper.

Red: What name would I use?

Red: Jasmine?

Red: Nah, that's too overused.

Red: So is Diamond.

You: stiles

Red: No, I'm not gonna use my name.

You: stiles

Red: Maybe Amani?

Red: I've always liked that name.

You: STILES

Red: What?

You: youre avoiding the issue we have rn

Red: How am I supposed to react???

Red: It's not like I requested you to be my assigned Dom.

You: so you dont want this?

Red: No, it's not that. I just didn't expect it and I don't know how I'm supposed to respond.

You: well we'll be going down to town hall on thursday like we're supposed to meet for the first time and we'll talk about it then okay?

Red: Yeah... I guess.

You: hey stiles?

Red: Yeah?

You: is it okay if i read your file?

 

Derek frowned when he didn't get a response. Stiles was literally the fastest texter in the world.

 

You: stiles?

 

He kept waiting. It was difficult since he was terribly impatient but he was not going to read something so personal if Stiles wasn't okay with it.

 

Red: Would you be offended if I said I'm worried you'll use it against me?

You: what do you mean?

Red: I'm scared.

Red: I'm scared that you'll use it as blackmail or something.

Red: But mostly

Red: I'm scared it will change how you view me.

Red: Like, there are things that will make you see me as an entirely different person and I just

Red: Derek

Red: I don't want you to hate me

 

Derek froze. He had to read that again, multiple times. It was the first time he heard Stiles ever admit he was scared. And the reasoning behind that fear broke his heart.

 

You: when i told you about everything that happened with kate before i even said anything you promised me that you would never use anything i shared with you against me im making that same promise to you now and i swear to you nothing will ever change the way i feel about you

He saw the text bubble appear, then disappear, then appear again.

Red: Don't let anyone else read it, please.

Red: And please don't ask me questions about it. If it's something I'm okay with talking about, I'll tell you.

Red: There's just some stuff I'd rather not like to remember.

You: okay

You: hey i dont want you to think anything like that again that i would hate you because of something in the past okay?

Red: Yeah.

Red: Okay.

You: you should go to sleep youve got school tomorrow

Red: Dude. It's literally 10 pm right now. That's too early for me.

You: just try

Red: UGH fine

Red: G'night SourWolf

You: good night stiles

 

Despite the amount of protest Derek had given to that damn nickname Stiles had for him, it still made him smile.

Back to the issue at hand. Derek took a glance at the envelope. Did he really want to read it? It had Stiles' whole background and Stiles had seemed so worried that it would change their relationship. He knew he would never stop loving the teen because of something but, he wondered if Stiles was right. What if it did make him see Stiles as a different person?

In the end, his curiosity won, and he read it all.

Derek began to understand why Stiles would feel that way as he read about the boy's horrific childhood. It was the worst thing Derek ever heard off, he couldn't imagine the kind of Hell Stiles had been in. This was a kid, who always put everyone ahead of himself, yet, he had worse problems than anyone else but never said a single thing.

Stiles' mother died when he was three from an illness. Less than a year later, Stiles' father, John, a sheriff who was off-duty at the time, was stabbed to death in front of a four-year-old Stiles, who was also injured in the fight. Stiles was taken to a hospital and after three days, with no other family members stepping forward to claim him, he was registered into the System.

Derek was shocked when he read, at the first orphanage Stiles went to, it was discovered he was a Delta. Deltas were subs who could completely change their sex by will, meaning, a Delta who presented as a male could carry a child. All children born to a Delta were Doms.

Deltas were one of the most oppressed minorities with the highest amount of hate crimes. They were seen as sexual objects to be used whenever and were only good for having children. At one point, there was a hunt to track down and kill all Deltas after an influential preacher claimed they were abominations and were the cause of all the misfortunes the world was going through.

The Delta population was decreased by over 80%. They were already extremely rare, to begin with, and the remaining ones were either sold into sex slavery or they fled into hiding.

After reading about the discovery of Stiles' gender, he wasn't as surprised by the inhuman treatment Stiles faced growing up.

After six months in his first orphanage, Stiles was moved into a new one. There was evidence of, "multiple violent sexual assaults and physical abuse" on the boy's body but the reason he was moved was actually because of a fight he had with the Master of the House, his abuser. Stiles had claimed the Master was "hurting" him and accidentally kicked out which caused a fight ending in Stiles stabbing the Master in the chest with a pen. The therapist writing the report said after she asked him how he was being hurt, Stiles tried to explain it but didn't understand exactly what it was that was done to him. What he said though, proved that he was raped and implied that it may have happened to others in the orphanage.

Despite all of the proof they had, no charges were pressed against the Master. In fact, Stiles was the one who got in trouble and was put in solitary confinement for three months. The next orphanage he went to, he was placed in the psychiatric ward having been driven to near insanity by his confinement and the realisation of what happened after hearing the teenagers in the Home talk about how one of them lost their virginities at prom.

While in the new home, Stiles was abused again by two orderlies who would give him sedatives to make him stop fighting but he was still aware of what was going on.

This became a pattern. Stiles would be removed from one abusive orphanage into another and even into foster homes. When he was nine, his foster father discovered their seventeen-year-old son had become involved with the child. Instead of punishing his son, he nearly beat Stiles to death.

When he was ten, a different foster family he'd been given to, forced him into conversion therapy after seeing him and an older boy kiss. During this time, Stiles had his first suicide attempt by overdosing on painkillers. The only reason the family brought him to the hospital was that they would be investigated had he died and they didn't want the evidence of their abuse being found. The father had been locking Stiles in a tiny closet that had nails on the back wall and they'd been starving him.

He ran away and was homeless for a year before being found. He started a rebellion in a New York orphanage at twelve years old to fight against the mistreatment they were facing. He was transferred to a juvenile detention facility in LA and attempted suicide again by slitting his wrists. He was assigned to a Dom when he turned thirteen.

Derek never heard of a sub being assigned at such a young age. The youngest he'd seen was sixteen which was the age of consent but seventeen was the norm. They were only assigned if they caused trouble and misbehaved. Most subs left the System with no problems when they turned eighteen.

This Dom, Joseph, lived in Beacon Hills. Stiles began attending a real school for the first time. He was moved up a grade almost immediately. Derek was sure this was when he met Scott. After the two mandatory months being with Joseph, Stiles was going to ask to be assigned to someone else.

A police report details that Stiles was prevented from leaving. Joseph was trying to force Stiles into bonding to him when Stiles turned sixteen, the age when Deltas can actually mate. Over the course of Stiles' life, he had learned to fight a Dom's Voice and refused to agree.

Authorities began looking into the case after someone reported they believed Stiles was being abused. After two days of missing school, a friend stopped by the house to check out what was going on. The student found Stiles, beaten viciously with no sign of Joseph anywhere. The police report then claims, the student carried Stiles out and brought him to the hospital where his mother worked.

There, Stiles lay in a coma for nearly two weeks. After waking up and lots of physical therapy, he was given to the student's mother when she filed for foster care. He knew that was Melissa and that meant Scott had been the one to find Stiles and save him. Derek would be sure to thank him.

Joseph was never found. Stiles had ended up in Rehab three times for heroin and alcohol since then and struggled with self-harm. After a court order, Stiles started visiting a psychiatrist every other week. Apparently, he made three others retire. Stiles often said mind games have always been his favourite thing. Derek would like to see someone try and get into Stiles' head, the kid would tear them apart.

After reading everything, Derek felt a stronger connection to Stiles than he ever had before. It did change the way he viewed Stiles. He already knew Stiles was probably the most loyal, caring, and compassionate person he'd ever meet.

This boy had been through so much in his life and yet, he still tried to improve the lives of others. Derek never respected anyone as much as him. And he loved him. Stiles was his mate and he loved him, no matter what.

He wanted Stiles to be his sub. He wanted Stiles to feel safe. He wanted Stiles to be happy and he swore then and there, he would do everything in his power to make that happen.

Chapter Text

Stiles was dreading receiving his letter. He was perfectly content at the moment. Living with his best friend, being in the Pack, having Derek finally accept that Stiles wasn't going anywhere no matter how hard he tried to get rid of him. The world's oblivious to werewolves and the supernatural. How would he explain to his Dom, the attachment he had to Derek, his Alpha. He wasn't going to allow anyone to take him away from his family. It wasn't to say, Stiles didn't want a Dom. Being a Delta, without a Dom was difficult. He just didn't want one who would limit him.

His whole life, people tried to control him. Now, he was going to decide who could tell him what to do.

He knew how to frustrate a Dom to the point where they would file for re-placement. He was pretty much preparing himself for it another Joseph. He shuddered thinking about the man, who still hadn't been found.

Stiles' biggest fear was being prohibited from seeing the Pack. Joseph had refused to allow him to see Scott. The Pack had given Stiles that feeling of family he had longed for, for so many years. He didn't want to lose that. 

He didn't like the idea of another sub in the Pack, either. To be honest, he was jealous as Hell. He and Derek had finally started getting along, and it was going to be ruined by some other bitch. 

There could only be one, and Stiles was the Queen Bitch

He thumped his head against the table, groaning when he came home late from practice one day, to see the yellow envelope he'd seen many times before. 

He debated waiting for Scott to come home to open it with him but he had always been impatient, that wasn't about to change anytime soon.

He tore open the tab. Maybe, it was a woman? It was possible. Perhaps, that would be better. Statistically, it was far less likely for a woman Dom to be violent towards a Delta. Less likely doesn't mean impossible though, and Stiles braced himself as he unfolded the letter. 

Thank God for the lack of neighbours and the absences of Scott and Melissa because he legitimately screamed when he read the name.

Derek S. Hale 

Jesus on a tricycle. What the fuck was happening? 

He re-read the paper over and over again, sure it was a mistake. The possibilities of him being assigned to his own Alpha was less than a one percent chance. 

He had to admit, the idea of Derek as his Dom was appealing. It wasn't something he hadn't thought about before. It was the ideal situation, but Stiles never had anything in his life work out in his favour. 

His head was spinning so fast, he needed Derek's opinion on this. He fumbled around for his phone, scrolling through his contacts before finding Derek's and sending a text. 

You: Hey Dee? 

It didn't take long for a response. 

Mr. Grumpy: yeah? 

You: You wouldn't have happened to have read your sub letter yet would you? 

Mr. Grumpy: no why? 

Stiles sighed heavily. 

You: You miiiiight want to do that right now. 

He tried to focus on his school work but found it impossible. What if Derek said no? What if Derek said yes? Several agonizing minutes later, he received another text. 

Mr. Grumpy: is this for real? 

You: Yeppo. I got my letter detailing who my new Dom would be. Imagine my surprise when I read your name. Your middle name starts with an 'S' what does it stand for? 

You: Samuel? 

You: Stanley? 

You: Sabrina?

Mr. Grumpy: can we focus on this rn? 

He absolutely did (not) want to focus on this right now. 

You: Sure. 

You: I still wanna know what the 'S' stands for.

Mr. Grumpy: first try was right 

Psychic Stiles strikes again. 

You: Aw nice!

Mr. Grumpy: you got some name as well 

Ohhhhh shit. He forgot it would have his real name on it.

You: Not my idea, obviously. See why "Stiles" is so much easier? 

You: Mom was Polish. 

You: Decided it was a great idea to give her kid literally the most difficult name ever.

You: Try spelling it to an old person on the phone when calling to see how much money is in your bank account. 

You: Takes half an hour to find out, I have $0.36 

You: I need another job.

You: Like I have two already but the majority of the money goes to helping Scott and Melissa.

He started rattling on about becoming a stripper and what his name should be. His main defense besides sarcasm... derailing a conversation and changing the topic. 

Mr. Grumpy: STILES 

You: What? 

Mr. Grumpy: youre avoiding the issue we have rn 

OBVIOUSLY.

You: How am I supposed to react???

You: It's not like I requested you to be my assigned Dom.

Mr. Grumpy: so you dont want this?

Oh, wow. Instant guilt.

You: No, it's not that. I just didn't expect it and I don't know how I'm supposed to respond.

Mr. Grumpy: well we'll be going down to town hall on thursday like we're supposed to meet for the first time and we'll talk about it then okay?

You: Yeah... I guess.

Mr. Grumpy: hey stiles? 

You: Yeah? 

Mr. Grumpy: is it okay if i read your file? 

Oh, shit. Oh, fuck. Oh, fucking shit. What was he supposed to do? Did he really want Derek knowing about everything? He'd never told anyone anything whatsoever. Not even Scott.

The last thing he wanted to do, was to destroy his relationship with Derek. Would it make Derek view him as the little defenseless human again? More importantly, would Derek hate him because of what he was?

When there was a sudden spike in hate crimes against Deltas, he heard Derek talking about it. He said he'd protect a Delta if he ever met one and that no one deserved to be treated so horrible, regardless of gender or race. 

Saying something and doing something was completely different. Would he react differently when faced with an actual Delta? Would Derek think he was disgusting because of how used his body was?

He didn't want Derek to see him any differently. What if he held it over Stiles' head? What if he threatened to tell the rest of the Pack if Stiles didn't do something he told him to? He didn't want anyone else knowing. The questions they would ask would without a doubt, bring up some things he didn't want to think about.

He was apparently taking too long thinking as he got another message. 

Mr. Grumpy: stiles? 

Fuck. He had to say something. Derek was asking permission, trying to respect his boundaries. That had to count for something, right?

You: Would you be offended if I said I'm worried you'll use it against me? 

Mr. Grumpy: what do you mean? 

You: I'm scared.

You: I'm scared that you'll use it as blackmail or something. 

You: But mostly 

You: I'm scared it will change how you view me.

He felt tears flood his eyes, blurring the screen as he typed. 

You: Like, there are things that will make you see me as an entirely different person and I just

You: Derek

Stiles rarely ever said Derek's full name. He felt so many emotions bubbling inside of him. 

You: I don't want you to hate me

Stiles felt like his world was crashing down around him and nearly sobbed with relief when he saw Derek's response. 

Mr. Grumpy: when i told you about everything that happened with kate before i even said anything you promised me that you would never use anything i shared with you against me im making that same promise to you now and i swear to you nothing will ever change the way i feel about you

He didn't know what to say. No one had ever kept their promises. Why should he trust Derek?

He thought about it for a moment. To finally confide in someone. To actually trust someone. If Derek was being honest, Stiles would finally have someone there for him.

You: Don't let anyone else read it, please.

You: And please don't ask me questions about it. If it's something I'm okay with talking about, I'll tell you.

You: There's just some stuff I'd rather not like to remember.

Mr. Grumpy: okay

Mr. Grumpy: hey i dont want you to think anything like that again that i would hate you because of something in the past okay?

You: Yeah.

You: Okay.

Mr. Grumpy: you should go to sleep youve got school tomorrow

Stiles nearly snorted at that. 

You: Dude. It's literally 10 pm right now. That's too early for me.

Mr. Grumpy: just try

You: UGH fine 

You: G'night SourWolf

Mr. Grumpy: good night stiles

He didn't know it was possible to feel so relieved yet so worried at the same time. Someone else would finally know what he'd been through but he didn't know what kind of reaction Derek would have.

He wanted the whole world to just delete itself at the moment. He couldn't stop thinking so, in typical Stiles fashion, he decided to go out, get drunk and find a good fuck. 

He was by no means a lightweight so he was intending on drinking a lot. He wanted to get absolutely shitfaced drunk and make lots of bad decisions. He was ready and out the door with his fake ID in a matter of minutes.

_________Scott's POV______________________

Scott had been a bit concerned when he got home late and found Stiles not there. Stiles had left lacrosse practice early, not an unusual thing since he was barely allowed to play anyways.

It made him even more worried the next day when class started and Stiles still wasn't there. Scott was sitting with Lydia, Isaac, and Erica as Coach began to give a lecture.

Everyone turned when they heard the door open to Stiles walking in. Holy shit. He sat down behind Scott and the werewolf cringed when he smelled, even after taking a shower, the alcohol and the scent of another guy on Stiles. 

"Not looking too good there, Stilinski. Everything all right?" Coach asked, a bit pissed at having been interrupted. "Had a long night," Stiles said, dismissively.

"Hmm, really? Care to share?" Coach asked with a smirk on his face. "Not particularly. Care to teach?" Stiles raised an eyebrow at him. Oh no. There were several snickers around the room as Coach's face went serious. "Hallway. Now," he said, angrily.

When Stiles got up, he rolled his eyes so hard Scott thought they would fall out. That just pissed the man off more, "you just got yourself an afterschool detention," Coach shouted, pointing at the teen.

Stiles practically kicked the door open, "I'm flattered that you would like to spend another hour with me but, I think we should just stay friends."

The room broke into fits of laughter but Scott and the others only looked at each other with concern. Something wasn't right. Scott had seen Stiles hungover many times before, he didn't act like this. 

After several minutes of hearing Coach's muffled shouting, they finally walked back in. The 'wolves could smell the anger on Stiles. He was fucking pissed.

"If you're gonna act like a child, you're gonna be treated like a child," Coach said to the class. Stiles was about to sit down but he paused. He glared at the teacher, a look that actually scared Scott, and instead grabbed his bag, walking back towards the door.

"What do you think you're doing? COME BACK HERE!" Coach demanded. "Nope. I'll see you at detention," Stiles' voice was faint as the door closed behind him.

It was one of the only times Scott had ever seen Coach Finnick, speechless. "McCall... what the Hell was that?" he asked, slowly. "I have absolutely no idea," was all he could say. 

________Derek's POV_________________

He got home about twenty minutes later than he had originally anticipated. The Pack was altogether in the main library by the time he arrived. He looked around and saw there was one person missing. The one person he needed to talk to, of course.

Before he could ask, Peter beat him to it, "where's Stiles?" Derek saw the look Lydia shot at Scott before the teen said, "he... uh, he got detention." Jackson snorted, "what did he do this time?"

"We don't know what was up with him but he talked back to Coach, more than usual," Erica said. "He was super hungover but he doesn't normally act like that when he's got one," Scott said.

"So, what actually happened?" Laura asked. "Well like Erica said, he talked back, Coach pulled him into the hallway and yelled at him a bit and when they came back in, instead of sitting down he literally just walked out the classroom," Scott said.

"I... actually have it. On video," Erica said. All eyes turned to her. "I was Snapchatting a friend and managed to catch everything after Finnick told him to go into the hallway."

Danny helped her hook up her phone to the large television in the room they had their movie-nights in. They watched as Coach yelled at Stiles after he rolled his eyes and when they heard the comment Stiles made about, "just staying friends," Peter broke into a fit of laughter.

"Ah, God, I love that kid. He's the best," he said, wiping tears from his eyes. When they saw the look Stiles gave Coach after returning to the class, there were quite a few murmurs as to what made Stiles so pissed. It kind of shocked them all when he just grabbed his stuff and left, pretty much turning the tables and dismissing the teacher instead. Stiles tried to avoid drawing that much attention to him and that was most certainly a grand exit people would remember. 

"I really want to know the context of this. Do you know when he'll be here?" Cora asked. Lydia looked at the clock and said, "half an hour, maybe." Scott shook his head, "depends on if he starts causing trouble while he's in detention. He can turn a one-hour into a four-hour in seconds."

They would have started talking about their newest monster but, Stiles knew more than anyone about it. He usually knew everything about a creature before any of them even had a clue what it was. Scott sent Stiles a text asking him to tell when he got out. 

About an hour and a half later, Scott got a response. He paused for a moment and squinted at his screen before leaning over towards Lydia and showing her his phone. "That doesn't seem right, does it?" he asked. Derek was thankful he wasn't the only one with confusion written on his face.

"No. That's not right," Lydia said, she looked up at the others, shaking her head. "This isn't the way he texts. He's all about grammar and punctuation. This is all misspelled and jumbled," she said, brow furrowed.

Scott started speaking out loud as he typed, "are... you... okay?" They waited until they heard the phone vibrate. Scott and Lydia looked at each other, perplexed. "He's not making any sense. I'm gonna call him," Scott said. "Put him on speaker," Cora chimed.

They listened as the phone rang multiple times before going to voicemail. Scott called again and Stiles finally answered, "mm not in th mood tah talk, Scotty" he slurred out. Scott shook his head in bewilderment, "are you drunk?" he asked. 

"Very. 'Scuse me while I go back tah gettin' shitfaced again," he mumbled before hanging up. "He came to school with a hangover, and he's drinking again?" even Jackson looked slightly worried.

Scott sighed, standing up and patting his jeans for his keys. "Where are you going?" Kira asked. "Trying to stop him from getting alcohol poisoning," he said, a sad look on this face, "this has happened before and if someone doesn't stop it now, he'll start doing other stuff and it'll just gonna get worse."

"I got it," Derek said, grabbing his jacket. "I'm pretty sure I know why he's acting up, don't worry," he said when he was faced with questioning looks. "Then why is he doing this?" Peter asked eyebrow raised.

Derek just glared at him, "long story," he said before walking out the door, car keys in hand.

He tried to stop himself from thinking too much as he made his way to Scott's house, where Stiles lived. He didn't bother with the front door, no one would answer. Instead, he climbed up the tree to Stiles' bedroom window.

He flinched away, hand burning when he touched the sill. Mountain Ash. Thankfully, he had forgotten to take out the rag he used when working on cars, from his pocket. He used it to cover his hands while he lifted the window.

He may have accidentally broken the lock but he could deal with that later. Stiles was curled up on his side on the bed. He was actually awake and tried to cover his head with the blanket when Derek stepped in.

Derek could smell the alcohol on the teen. He growled when he caught the faint scent of another man too.

He walked over and tapped lightly on the small lump under the covers. It moved just slightly and Derek heard a groan when he tapped again. "Stiles," he said, "let me see you."

"Nooooo," a muffled voice came from under the blanket. "Go 'way," the voice whined. Derek sighed and said, "Stiles, come out now," in a pointed tone.

The covers moved as Stiles tried to shift away from him. Derek grabbed onto the blankets and tore them off. "Oh fuck off, man," the teen groaned, burying his face in the pillow.

Stiles was wearing a short sleeve shirt and Derek could very clearly see dark hickeys blemishing the smooth skin under the teen's collarbone.

He clenched his jaw hard and instead pulled Stiles up into a sitting position. The boy was fighting him all the way, fists flying out and shouting. Eventually, he just pulled Stiles into his lap and leaned against the headboard.

Stiles had frozen in his confusion and it gave Derek a chance to place a hand on the back of the teen's neck. It was a trick he'd seen many Doms do. It always calmed down their subs and, thankfully, it worked on Stiles too.

The boy went completely limp and curled up against him, letting his head rest on Derek's shoulder. In that moment, it felt so right. Having Stiles in his arms. It was how it was meant to be.

"Sorry," a quiet voice mumbled into the fabric of his shirt. "It's okay," he said, letting his other hand lay on Stiles' thigh. "No. Mm sorry," he said again, "did somethin' stupid." He buried his face.

Derek could hear him choking up, "you're gonna hate me." Derek's heart ached when Stiles sobbed out, "Scott's gonna hate me." 

"You know that's not true, Stiles. Scott would never hate you and neither would I," Derek said. Stiles shook his head, "I broke mm promise." He was on the verge of hysterics.

"What happened?" Derek asked, trying to keep a calm voice. "I used again. I relapsed. I promised Scott I wouldn't d-do," he choked on his words.

It hit Derek like a ton of bricks. It had said in Stiles' file that he'd been to rehab several times because of heroin and other drugs.

The teen was shaking. Derek pulled him close, letting Stiles' arms wrap around his neck. Stiles was stuttering out apologies, tears cascading down. 

They spent a long time like that. Derek shushing Stiles, trying to calm him down every time he thought of a new scenario about what his next encounter with Scott would be like. He would have brief moments of clarity, where he would think rationally. One second he would be calm, the next second he would get angry, and then sad, and then a mix of emotions.

After Stiles finally calmed down, Derek contemplated whether or not it was a good idea to say it but, in the end, he bit the bullet. "We're gonna go back to the House. You don't have to see anyone, we'll go straight upstairs. I just want to keep an eye on you, okay?"

He heard Stiles' heartbeat pick up slightly but the teen was too exhausted from the combination of an emotional breakdown, drugs, and a lot of alcohol, to do anything. He gave a hesitant nod and allowed Derek to pick him up. 

Derek opened the car door and buckled Stiles in. He sent a quick message to Lydia saying he was bringing Stiles back but the Pack was to leave him alone. She sent a confirmation that the others had been informed and only asked if Stiles was okay. Derek responded with, "he will be." 

The car ride consisted of Stiles trying not to fall asleep and Derek glancing over at him every so often to check on him. When Derek went to carry Stiles inside, he saw all the windows filled up with the worried faces of his Pack, trying to see the teen in his arms. 

He took Stiles straight up to his own bedroom and the boy was asleep the instant he was laid on the bed. Derek stripped him of his shirt and trousers but left on his boxers. He was trying his hardest not to admire Stiles' body, the hour-glass shape and the wide hips with the softest, hairless skin. It was always covered up under the layers of baggy clothing Stiles wore. 

He tucked the teen under a blanket and made his way to the main library. He was immediately surrounded and berated by questions fired off rapidly. They were all talking over each other and Derek had to yell at them to stop it. "One at a time," he said.

"Is he gonna be okay?" an extremely distressed Isaac asked. He and Stiles were so close Isaac viewed the younger teen as a mother figure. He even got Stiles a present on Mother's Day. 

"He'll be fine. He's just sleeping it off," he said. "What actually happened?" Allison asked. "Left detention, got drunk, had a lot of mood swings," Derek replied as he tossed his jacket on the couch. 

"What's going on with him? Why's he acting out?" Boyd asked, surprising everyone. Boyd rarely ever talked. Derek didn't know if Stiles would be okay with the Pack knowing about his Dom assignment. "It's Stiles. God only knows what goes on in his head," he said, collapsing into his chair.

After several more questions and some reassurance from Derek, the Pack began to relax a little, knowing Stiles would be okay. When some time had passed and the others started focusing on conversations and research, Derek caught Scott's attention and directed him to another room.

"Is he actually okay?" was the first thing out of Scott's mouth. Stiles had wanted Derek to tell Scott for him because he didn't think he could face his best friend and say it. Derek was completely honest, he shook his head and told him. 

"He used," he said. Derek felt horrible when he saw Scott's face drop. The 'wolf looked towards the ground, trying to hide the tears in his eyes. "H-he promised me though," he said, attempting to control his emotions.

"I know, he told me about that. He was actually having a meltdown because of it. He kept saying you were gonna hate him," Derek said. Scott sighed heavily as he wiped his eyes, shaking his head. "No. I could never hate him I just... I don't know what to do. It gets so bad," he said, pain evident in his voice.

It wavered as he continued, "I worry, all the time, that I'm gonna find him dead from an overdose or he's committed suici-" he clapped a hand over his mouth. "Scott, I know everything. The sub I was assigned is Stiles," he said.

Scott's jaw dropped so fast Derek was worried it may have hurt him. "Are you serious?" he asked in disbelief. His face grew stern, "is that why he's doing all of this?" Derek sighed, "I think he's freaking out at the thought of another Dom after Joseph and that I've read his file and I'm the only one who knows his whole life story." 

He looked at Scott, "you're the one who found him after... you know." Scott had a pained expression as he nodded, "I still can't believe someone could do something like that. Nobody deserves that, especially not Stiles." 

Derek couldn't agree more. Knowing everything that kid had been through, he had so much respect for the strength Stiles had.

"When do you think I'll be able to talk to him? I just need to let him know... I'm not angry or anything. I just want him to be happy and healthy and God, Derek, they make him take all these medications that don't work. They make him sick and he'll have these random meltdowns and he didn't even recognise m-me," his voice hitched at the end.

"I don't know when. Maybe tomorrow? I don't know how fast he recovers," Derek replied. Scott sighed and tried to himself together when they heard someone calling for them. When he walked past Derek, he turned to the Alpha and said, quietly, "be good to him. Please." Derek nodded, "I promise." 

 

Chapter Text

Derek went upstairs every so often to check on Stiles but, the teen had barely moved at all. Being a Tuesday night, the Pack disbanded at around nine, returning to their own homes. Scott stayed behind a little longer to talk to Derek. He didn't ask about anything on Stiles' file. The two had fought before when Scott asked too much. If Stiles wanted him to know something, he would tell it himself.

They talked about what the assignment would mean for them. Stiles would have to move into the House for two months. The whole relationship between Derek and him would change. Scott was concerned about Stiles' how it would effect Stiles' mental health. It would surely bring up some things he wanted to forget. Derek was way more aware of that than Scott was.

They agreed to keep the information about the assignment, a secret from the others until Stiles said otherwise. Melissa would be the only one to know as she would have to fill out the papers resigning Fostering. Scott told him about the extent of Stiles' addiction. It had gotten to the point where he was using multiple times a day. This relapse, while it may have been only once, was bound to cause withdrawal since Stiles' body recognised the substance.

Scott departed home, leaving Derek to watch over Stiles after informing him of what signs to look out for. The Alpha walked up the stairs to check on the teen and found him sitting up on the bed, knees pulled close to his chest with his head resting on them. He didn't look up when the door opened.

Derek walked over, sitting on the bed next to him and laying a hand on the boy's back. "Scott wanted to talk to you," Derek said, "to tell you he's not angry." Stiles lifted his head, wiping at his tear-stained face, "he should be though. I broke my promise."

"He knows about the assignment," Derek said, gently. "Does he blame you for what I did?" Stiles asked, sincere concern in his voice. "No. We talked about that. I think he understands why you would be upset considering what happened with Joseph," Derek felt guilty when Stiles twitched at the name, pursing his lips and looking down.

"So... you know. Everything. You know everything about me," he said. Derek could hear the mix of emotions in his voice. "No, I don't. I know some of the shit you went through. But, I don't know you. I want to know WHO you are not WHAT you are because that doesn't matter to me. Delta or not, you're still Stiles."

Derek was a bit startled when Stiles threw himself onto him, wrapping his arms around Derek's neck and burying his face there. Derek pulled the teen, fully into his lap, soothing his back in small circles.

Stiles was shaking as if he was cold but Derek could feel heat radiating off of him.

Fever, one of the signs Scott warned.

"Have you eaten anything today?" Derek asked, gently. Stiles shook his head. "Alright. Come on, let's get you something," he said, releasing his grip on the boy. Stiles pulled his jeans and long-sleeved shirt back on.

Derek led Stiles out of the room, arm wrapped around the teen's waist, mindful of his shakiness. Derek placed him on one of the bar stools and set to work making something for the two of them. He tried to think of any recipes but drew a blank. He hadn't cooked for someone else in a long time.

"Is pasta okay?" Derek asked. Stiles was resting his head on his folded arms, "I'm not really hungry." Derek grimaced. Nausea. Another sign. "Will you try to take even just a bite?" he asked. Stiles glanced up at him, completely silent for a moment before giving a small nod. Derek was aware of the teen watching him while he cooked.

He paused when he saw, out of the corner of his eye Stiles turn his face into the crook of his arm. The other hand gripped at his hair. "How you feeling, Red?" he asked. Stiles seemed like he was too tired to even lift his head and let out a quiet groan, "not very well."

"What about up here?" Derek asked, tapping his temple. Stiles glanced, taking a moment to understand what Derek was asking. "I think my brain is still trying to process it all," he said, "I thought they finally gave up on trying to 'fix me' and turn me into a 'law-abiding sub that knows his place in society.'"

Derek placed a bowl of pasta in front of the boy, who looked at it with slight contempt. "You don't have to eat it all. Just try some," he said as he sat next to Stiles and began eating his own food. The teen's hands were shaking as twirled his fork and took a bite, grimacing slightly. "You don't like it?" Derek asked. "No, it's not that. Everything tastes bitter when I'm like this. Even water tastes bad," Stiles said.

That was another sign of withdrawal Scott warned him about.

Stiles took a couple more bites before shaking his head, "sorry," he said, pushing his bowl away. "It's fine. I'm glad you ate something," Derek responded, still feeling the heat of the fever radiating from the teen. They were both caught off guard when Stiles' cell phone rang. The name on the screen said 'Pelzanie.'

"Who's that?" Derek asked. "Peter. That means 'Creep' in Polish, by the way," he said. Stiles put the phone on speaker.

"What can I do ya for?" he asked. "Well, first of all, are you alright, Kid?" The genuine concern in Peter's voice surprised Derek. "Yeah, I'm good," he said and Derek could hear his heartbeat falter. He was lying.

"Okay. Good. So, our new monster just so happened to have left a little present at Doug's Pub right outside Beacon Hills," Peter said. "Oh, great. What kind of present?" Stiles asked. "Two dead bodies and a part of someone's liver," Peter responded, bluntly.

"Wow. Lovely," Stiles said, sarcastically. "Just thought you might want to know 'cause it seems like it's headed towards the high school," Peter said, cheerily. "Yeah, I'll check it out, tomorrow. Thanks," Stiles answered. "No problem. And seriously, you can call me you know? If you ever need to talk to someone," Peter said, seriously. That put Derek on edge a bit.

"I know, you tell me all the time, P. I'll let you know how the check out with the school goes, alright?" Stiles said. "Okay," Peter answered. "Right, peace out," Stiles said as he ended the call. "When did you two get so close?" Derek asked, trying to keep his voice level. Of course, Stiles saw right through it. "Are you jealous?" he grinned. "I just want to know," Derek shrugged.

Stiles gave a doubtful look before pausing. "Can we watch a movie?" he asked. Derek thought for a moment, it was getting pretty late but it was obvious Stiles wasn't going to attend school tomorrow. He was only going there at night to find something on their monster.

"Sure. Which one?" he asked and preened when Stiles smiled, probably having thought Derek would say no. "Ever seen any Studio Ghibli?" Stiles looked horrified when Derek shook his head. "How are you even alive?" he asked, astonished. Derek rolled his eyes and then helped Stiles up, leading him to "the Den" where the Pack has their weekly Puppy-Pile.

They were looking through a bunch of movies when Derek saw Stiles smirk. Shaky hands snatched the remote from him and Stiles said, "close your eyes. No peeking." Derek huffed but did it. He heard some giggling and tried to look between his fingers. "Nuh uh. I said no peeking!" Stiles whined. Soon enough, a movie started and Derek snorted when he saw wolves run across the screen.

He had to admit, Princess Mononoke was actually really good. They had started out spread apart but less than fifteen minutes in, they were huddled together, Derek's arm around Stiles. The teen shifted uncomfortable for a moment, clutching his right shoulder and cringing.

Derek thought maybe Stiles was just nervous about their new situation. "Derek?" he asked in a hushed tone, "can I... be on your other side?" It confused Derek for a moment but through the dim light and with the aid of his heightened sense of sight, he could see a look of pain on Stiles' face. Even without his werewolf strength, Derek could have easily lifted Stiles with one arm.

The boy let out a relieved sigh when he snuggled in close to Derek's other side. Derek pulled a blanket over for him which Stiles gladly accepted. Despite his wolf heat and his own fever, Stiles was cold. The blanket didn't cover his shoulder and Derek couldn't help but notice Stiles still had a hand on it. Derek replaced it with his own hand and he felt Stiles tense up immediately.

He rubbed lightly at the muscle there and the teen literally melted into him with a soft moan. Derek rubbed around, focusing on Stiles' body language to figure out what he did or didn't like. He was a bit concerned. He could feel some sort of damage. The bone felt chipped and ragged while there was a lump going through the muscle. Derek immediately recognised it as scar tissue.

He'd always wondered why Stiles was constantly dislocating it in lacrosse and always laid on his left side. He remembered when Scott accidentally pulled on his arm and Stiles let out a pained yelp. Derek thought maybe Scott's werewolf strength had pulled on his wrist but now he knew it was actually his shoulder that was hurt. There was an injury there that weakened it.

Derek was able to keep up with the plot of the movie which was a good thing since Stiles would question what he thought of it. It was a really good movie but Derek was having trouble focusing with Stiles pressed up against him and letting out small, breathy moans.

It was nearing 2 am when the movie ended and Derek himself was feeling pretty tired. He rarely stayed up this late but he knew Stiles was usually still awake at this time. Derek thought it was absolutely insane. The kid would go to sleep at 4 and wake up at 6 and was somehow able function. Derek went to bed at 10 or 11 and got up at 8 and if he got any less than that, he felt exhausted. He knew he would have to call in sick tomorrow.

There was no way he could go to work, not with that amount of sleep and certainly not with Stiles at home alone. Derek had seen people go through withdrawal before. He remembered sometime before the fire, his older cousin's husband had alcohol withdrawal. It was bad and Derek thought Stiles was handling himself pretty well.

"Can we go to bed?" a quiet voice asked. Derek nodded and helped Stiles up. When they reached the top of the stairs, Derek felt Stiles pull away from him. "Where are you going?" he asked. He was able to see through the dark, Stiles pointing to "his" room.

When the House was rebuilt, every Pack member got their own room in case they wanted to stay over. Stiles picked a room that was fairly small compared to the others. The walls were completely covered, from wall to ceiling, in case files and newspaper clippings. There were stacks of books everywhere and Derek wondered how someone with such horrible ADHD could sleep in a room like that.

"No, you're gonna stay with me tonight," he said. If the lights were on, Derek was sure he would see a bright blush on the teen's face. Stiles nodded and followed him into the bedroom he was in earlier. Derek paused, "you don't have a toothbrush, do you?" Stiles raised his eyebrows, "how much do you know about Deltas?" Derek shook his head, "not very much."

"Well, one of the things is, our bodies kinda naturally clean themselves. Like, unless there's mud or something on me, I don't actually have to take a shower or worry about any stuff like that."

Wow. Derek was sure to do some more research later.

He himself felt much in need of a shower. He came out of the bathroom later wearing just a pair of sweatpants. He couldn't help the satisfaction he got when he saw Stiles, who was under the covers, pretending like he wasn't ogling his abs.

He climbed in and Stiles squeaked when Derek pulled him in so his head was resting against Derek's chest. He felt Stiles shifted slightly and before he could stop himself, he asked, "what happened to your shoulder?" Stiles jolted a little. Derek could tell he was biting his lip. The teen let out a sigh, probably realising there was no reason to hide anything since Derek knew pretty much everything already.

"I tried to help my dad when..." he trailed before taking a breath, "when he was killed. I tried to stop the guy but... he stabbed me when I got in the way."

Derek clenched his jaw and tried to stop himself from saying anything. He wished he could tear that piece of shit apart.

"It went completely through my shoulder but a part of the blade broke off in my shoulder but at the hospital, no one did anything whatsoever to help. After a day, I just had to pull it out myself. It never healed properly."

Now Derek was really pissed. How could anyone do that? A little four-year-old just watched his father get stabbed to death and has a piece of the knife that killed him, going straight through his shoulder.

"What kind of damage did it do?" he asked, trying to keep his voice level.

"I didn't know until Melissa took me to get an x-ray after seeing there was something wrong," he gave a sad chuckle when he said, "there's actually still a little piece left. The knife cracked my collarbone and then went all the way through my shoulder blade. It cut a part of the joint that holds your shoulder in place, which is why I keep dislocating it."

Derek wrapped an arm around the teen's waist and inhaled his not-yet-mate's scent. He intertwined his other hand with the smaller, softer one resting on his chest. He felt Stiles smile against his skin when he pulled him as close as physically possible. The teen pursed his lips, "you know your sister ships us, right?"

It took Derek a moment to remember what the word 'ship' meant.

"Which sister?" he asked. "Actually, both of them do. Peter too." Derek gave a doubtful snort. "I'm serious! He bet on it!" Stiles giggled, "Jackson said it would never happen and I kid you not, Peter bet FIFTY on it."

If Derek had a free hand, he would have facepalmed as Stiles informed him of all the people who 'shipped' them. He grinned.

Maybe it wouldn't be so hard to tell them about the assignment

Chapter Text

Derek woke up twice to hear what sounded like coughing from the bathroom but realised it was Stiles retching. He got up to comfort the shaking teen, rubbing his back and wiping away tears. Nothing actually came up, it was just dry heaving but the boy was obviously miserable. The muscle cramps started an hour or two later, adding to the poor kid's suffering.

The 'wolf did everything he possibly could to comfort him, but there was very little he could do other than hold him close and be there for him.

Derek woke up way after 10, groggily at first, but then panicked when he realised the teen wasn't next to him. He was still concerned about Stiles' physical as well as mental health. His worry ebbed away when he smelled something absolutely delicious, wafting through the door and loud music playing, muffled by the walls.

He walked into the kitchen and saw Stiles, dancing around at the stove, skillfully flipping an omelette. Derek took a while to appreciate the sway of Stiles' hips to the beat of a Gorillaz song.

The teen jumped, gasping in surprise when Derek wrapped his arms around him, letting out a chuckle next to his ear.

"Give a girl a heart attack, I swear," Stiles tutted.

He paused for a moment, blushing.

"Uh, um, forget I said that. Slip of the tongue-tip of the shlong. You know how it goes," he shrugged, and Derek snorted loudly but made a mental note so as (not) to forget it.

"How are you feeling?" he asked.

Stiles sighed, "well, I'm not nauseous anymore, so that's good. I'm still a bit shaky though. Fever is gone and no more muscle cramps."

Derek leaned down to nose at Stiles' neck, breathing in his sweet scent, the one that drove the werewolf absolutely crazy. Stiles practically preened and tried to hide a grin. "Can you pass me a plate, please?" he asked as he turned off the heat.

"Since you asked so nicely," Derek said, reaching for one. He did a double take when he handed it over. He grabbed Stiles' cheek and tilted his head to the side and inspecting his neck.

"What, Derek? What's wrong?" Stiles asked, alarmed.

"They're... gone?"

"What? What you on about?" Stiles started panicking.

"No no. You had marks... hickeys. On your neck. They aren't there anymore," Derek said, extremely confused.

"Jesus Christ, Derek. For real? That's what you're freaked about?" Stiles looked at him, incredulously. Derek just stared at him.

"It's this thing," he said, holding his wrist out and pointing to a small tattoo. Derek ran his finger over it and asked, "what is that?"

"I knew about the supernatural world before I even came to Beacon Hills, my best friend when I was little, Nina, she was a werewolf. There was a girl named Anna at a Home I was in. Her sister was a Delta that was killed in a hate crime. She found ou- wait... did you do any research on Deltas?"

Derek shook his head. He hadn't had any time to.

Stiles sighed, "okay. Basically, Deltas are born with a symbol right here," he said, placing his hand on the left side of his lower back, just below the ribs.

"It's a dead giveaway as to what we are. Someone... tried to get rid of mine but, it didn't work. Anna found out about what I was and wanted to help me. She was a witch. She made a rune to hide the symbol. It was completely unintentional but, it ended up hiding all of my scars and as well as any damage a day or two after it occurs. It's kinda like a magic shield. I can let it down and put it back up whenever I want but, I like to keep it on."

Derek was silent for a while as he tried to comprehend everything. Something in that caught his attention. "What do you mean someone tried to get rid of your mark?"

Stiles looked away, shifting uncomfortably, "there was an orderly who... wanted to keep me from being Fostered so I would have to stay in the hospital. He knew a Delta would immediately be snatched up if people knew. So, to keep people from finding out, he kinda... burned me with an iron to try and hide my mark."

What was someone supposed to say to that? Sorry? "Sorry" can't erase all of that trauma. Derek slid his arm around the teen, who melted against him as soon as he was embraced.

"Can I see you?" Derek asked and Stiles looked up at him in confusion. "I mean, you said you could let down the shield when you wanted. Can I see?"

Stiles blushed, biting his lip and driving Derek absolutely insane. "Derek, I am covered in scars. It's not a pretty sight. Trust me, you don't want to see it."

"Yes, I do. It's you, Stiles. Like I said before, I want to know you. All of you. Scars included. You don't have to hide from me. If you're not comfortable with it, just tell me," Derek said.

Stiles looked down in shame, "sorry."

"No," Derek said lifting the boy's chin to make him look back up at him, "don't be sorry for that. I hope, at some point, you'll trust me enough to show me but, don't apologise for telling the truth, okay?"

The teen huffed, "why are you just so perfect? It's not fair, dude."

Derek was stopped before he could speak by his stomach growling loudly. Stiles raised an eyebrow at him, "due to our little heart-to-heart, I have to reheat breakfast. Go sit down and put on whatever music you want."

Derek sighed as he let go of Stiles and sat down at the kitchen bar. He paused for a moment, trying to think of something to listen to. He remembered Peter and Stiles bonding over their shared taste in music after Stiles wore a Red Hot Chili Peppers shirt so that's exactly what he put on.

He saw the grin spread across the teen's face as soon as the song, "Can't Stop" started playing. Stiles mouthed the words, moving to the beat and Derek couldn't help but feel a little disappointed when the food was heated and Stiles stopped.

As soon as he took a bite, Derek thought Stiles was going into the wrong profession and should instead become a chef. Gordon Ramsay, who? He must have had some kind of reaction because Stiles started laughing, "is it good?"

He didn't even say anything, just made a noise but Stiles seemed to get the idea. "I'll take that as a compliment," he said, chuckling.

Stiles' phone started ringing on the table, playing the song "Sweet Child O' Mine" loudly.

"I'm gonna take a guess and say that's Isaac," Derek looked at him and Stiles nodded.

"How you doin Baebulah?" Stiles asked as he answered the phone.

Derek could hear Isaac answer, "I'm okay, Mama. Are you?"

"Yeah, I'm good, baby. Don't worry," he said and Derek was happy to hear his heartbeat stay steady.

Isaac let out a relieved sigh, "okay. Sorry, I just wanted to make sure. Class was so boring without you. I think even Coach was kinda sad that he didn't have anyone to pick on. Are you coming to the school tonight to check out that thing?"

"Yeppo. I'll be there," Stiles said.

"Okay. I'll see you later, Mama," Isaac answered.

"Bye, baby," Stiles grinned, voice filled with adoration.

Jesus Christ, that was so cute. Derek couldn't help feeling his heart warm up. Despite Isaac being a Beta (and mated to Cora), Stiles took him in as if he were his child. Isaac's father had been verbally abusive and even hit him a few times. It made sense that Stiles, with the sort of childhood he'd had, would have such a strong bond with him.

It always astounded everyone how Stiles could go from a total idiot to a protective mother in less than a second. Derek knew now that it was likely due to Stiles being a Delta but, he felt even if Stiles wasn't one, he'd still act the same way.

The kid was a genius, kind and caring, brave and willful and absolutely the most amazing thing ever.

"Dude, what?" Stiles let out a confused chuckle and Derek realised he was grinning.

"You are adorable," he said and watched the blush spread across the teen's face.

"I have no idea what you're talking about. I am a fearsome beast of nature," he said, pursing his lips and crossing his arms.

"Mm, yes. The wild Stiles. Spits venomous sarcasm when provoked. Handle with caution," Derek said, pulling Stiles' chair close.

Stiles snorted, "that was literally the best description of me I have ever heard."

Bright honey-hazel eyes made Derek still as Stiles looked up at him. Derek would never get tired of seeing them. Stiles mentioned once that he sees things in numbers and symbols and words. While people look at the big details, Stiles looks at the small ones. His mind never stopped and Derek loved watching the teen figure out things faster than anyone else.

Even at that very moment, Stiles' eyes held the ever-present curiosity and inquisitiveness that never faltered.

"What are you thinking about?" Derek finally asked.

Stiles seemed a little surprised at the question, "a lotta things."

"Like what?"

"Like the statistics and chances of being assigned to you when you're already my Alpha. How I managed to get from Brooklyn and end up here. What's the Pack gonna think when they find out? What am I gonna say to Scott? Just, a lotta things," he said, eyes straying before returning to Derek. "Also that you still haven't called in sick."

"Oh, shit," Derek huffed as he grabbed his phone, releasing Stiles. Derek didn't even need an actual job, he had more than enough money. He just liked having something to do other than Pack related things.

After some quick coaching by Stiles on how to sound sick, Derek called up the somewhat pissed off owner of the auto shop. Thankfully, Stiles was a great actor and bestowed his knowledge unto Derek which led the 'wolf to effectively fool his boss.

Derek made a mental note to keep in mind how easy it was for Stiles to trick someone like that, lest it be used on him. Despite being able to hear a person's heartbeat and tell when they were lying, Stiles knew how to cheat the "Werewolf System." He knew the exact way to derail a conversation or avoid giving answers that would definitely be a lie.

If you asked him a 'yes' or 'no' question such as, "are you okay?" He would answer with something like, "not too bad." Stiles would never admit that he was not okay but, if he said 'yes,' he would be caught in a lie.

It was something Derek had picked up on recently, even before the file. If someone asked a personal question, Stiles deflected it in a way no one would notice. People perceived him as an open book, yet no one had actually read the pages. Besides Derek at least.

Derek wondered how hard it must be for Stiles, to keep all those secrets secret; to never tell anyone anything. How hard is it having to listen to other people complain about totally insignificant things while never uttering a word about his own problems?

He looked up to see the teen gripping his shoulder lightly with one hand while sipping from a cup of coffee with the other still shaky hand. It seemed like he hadn't even known until he paused, noticing Derek's gaze.

"Is there anything they can do to fix it?" Derek asked.

Stiles gave a tight-lipped, sad smile, "no, it healed around the piece of the knife. They said it would have to be a total replacement; collarbone, shoulder blade, everything. Then there's still the issue of the muscle damage. They said while it would relieve the pain, it would only be able to function at about 60% of what it already is." He shook his head, "I'm gonna keep going till I can't anymore. I'd rather be in pain but able to do stuff than be free of pain but NOT be able to do stuff."

Derek clenched his jaw hard. If someone had treated him right away, they probably would have been able to fix it. Now, Stiles had to suffer yet another thing, because of their negligence. Hadn't the kid been through enough?

"Hey," Stiles gave a cheeky grin. "It could always be worse," he said, shrugging.

Derek couldn't believe it. How could someone, who had endured so much pain and tragedy in such a short life, be so positive? How could someone, who had been through the worst humanity had to offer, who had been so mistreated still try to put a smile on other people's faces?

"I was wrong about you," Derek said.

Stiles tilted his head in confusion, "what?"

"When I first met you, I thought you were this helpless, annoying human, who was dumb enough to trespass and walk around the woods in the middle of the night. The first time you talked back and didn't listen, I thought you were just a disrespectful kid, who didn't care about what anyone else had to say," he said, stepping forward and grabbing the teen's hands.

"I was so wrong about you, and I'm sorry. You are the smartest, most caring person I've ever met. You've dealt with things nobody should ever have to deal with. I said some horrible things to you to try and get you out of the Pack because I didn't think you could take care of yourself. I didn't want anything to happen to you," he paused wondering if he should continue when he saw the teen's eyes tearing up.

"Stiles, as soon as I met you, I knew you were supposed to be my mate. The moment you walked away from me, every instinct told me to follow you. But, I couldn't stand the thought of you getting hurt, so I tried to keep you out of the way. But, you are the most stubborn person ever and I'm glad you are. I'm glad you didn't leave. I enjoy every moment I'm around you, even when you're ranting about video games or superheroes and I act like it's bothering me. It's not, I love it and I don't ever want it to stop. I don't want you to be reassigned. I want you to stay here and be mine."

"In simple terms that even I can understand, Stiles Stilinski, I love you, and I don't want you to leave."

 

 

Chapter Text

Derek regretted saying anything when the teen pulled his hands away, completely silent. He had a cold look in his tear-filled eyes as he seemed to be scanning Derek's face. It suddenly struck Derek as to what he was actually looking for.

Stiles was searching for an indication of a lie.

It was possible no one had ever said anything like that to Stiles or if they had, it hadn't been sincere. Someone may have tried to manipulate him into bonding. It was highly likely considering what some people would do to claim a Delta.

It broke Derek's heart. He could practically see the battle the boy was having between logic and emotions, the struggle of wanting to believe him but not wanting to be hurt.

It felt like ages before the cold look turned to guilt as if he felt ashamed for not believing Derek. He looked away, biting his lip, tears falling.

Derek could hear the teen's heartbeat speed up as he took a step closer and lifted his chin. "Stiles, look at me," he said and there was a moment of hesitation before honey hazel eyes full of pain and conflict, met his own.

All words disappeared and Derek let instinct take over, kissing Stiles and praying he wasn't totally fucking up. Stiles was frozen for a moment before his brain seemed to finally process what was happening and reciprocated, kissing him back.

Shaky hands grabbed at his shirt like an anchor. Derek's own hands travelled to the boy's waist as he revelled in the softness of his lips and the taste of strawberries and vanilla. Arms wrapped around Derek's neck, pulling him down further to deepen the kiss.

Neither wanted to stop but it seemed like they both forgot how to breathe properly. When they separated, both were practically panting. Instead of pain, Stiles' eyes were filled with something else: genuine happiness.

Biting his lip the way that drove Derek crazy, he nodded, "okay."

Confused, Derek asked, "what?"

"I'll stay. I don't wanna ask for reassignment," he said, once again scanning Derek's face. This time he seemed to be looking for a sign of disapproval but was instead met with a wide grin.

The teen giggled as Derek picked him up, swirling him around and kissing him again. Derek had decided long ago that Stiles' laugh was one of his favourite sounds and this only solidified his opinion.

He couldn't get enough of the boy; his scent, his eyes, his lips, his smile, his silly little giggle, his horrible puns that made only himself laugh, his kindness, his sassiness and stubbornness, his everything.

There was nothing Derek didn't love about him.

They spent the next two hours on the couch, kissing and cuddling with Stiles practically on top of Derek while they watched a movie. Derek had noticed that Stiles' fidgetting became more prevalent as time past.

He felt like slapping himself in the face for his stupidity when he realised something. "When was the last time you took your medication?"

Stiles tensed above him slightly, shooting him a sheepish grin. "A day or two..." he trailed off and Derek sat up abruptly, startling him.

"You don't take only Adderall though, you take other things as well, right?" he asked, concerned. He didn't want Stiles going through another withdrawal.

Stiles groaned, "I hate them. They don't help, just make me feel sick. I don't want to take them anymore."

"You can't just stop them suddenly, Red. THAT will make you sick. If I take you to a different doctor, one who will actually listen to what you have to say and not just give you more pills, will you take your medication in the meantime?" he asked.

Stiles sighed heavily. "Fine," he said, letting his head fall against Derek's chest.

"Are they at Scott's house?" Derek asked.

Stiles nodded, "yeah they're in a locked cabinet. Only Melissa has the code."

Derek pulled back slightly to see the teen's smirk. "Only Melissa?"

"I mean... did you really think a little lock is gonna get the best of me? It's like too easy sometimes. I like a good challenge, every once in a while," he said nonchalantly.

Derek paused for a moment, "three playing cards in a row. There is a two to the right of a king. A diamond will be found to the left of a spade. An ace is to the left of a heart. A heart is to the left of a spade. Now, name all three cards."

"Ace of Diamonds, King of Hearts, Two of Spades," Stiles said, immediately. Derek stared at him in awe. He hadn't figured that riddle on his own. Someone had to tell him the answer.

With some reassurance that they could get milkshakes after getting Stiles' medications, he was able to get the teen off the couch and in the car towards Scott's house. On the way there, Derek asked more riddles to which Stiles answered in less than a second, correct every time.

"I am taken from a mine, and shut up in a wooden case, from which I am never released, and yet I am used by almost everybody. What am I?"

"Pencil lead."

"What has a head and a tail, but no body?"

"A coin."

"He has married many women but has never been married. Who is he?"

"A priest."

"What is as light as a feather, but even the world's strongest man couldn't hold it for more than a couple minutes?"

"His breath."

"How can someone go eight days without sleeping?"

"They sleep at night."

"Can you name four days that start with the letter 'T'?"

"Tuesday, Thursday, today, and tomorrow."

Derek thought and thought before he decided to use the longest riddle he knew, "I have four questions.
One: How can we put an elephant in a refrigerator?
Two: How can we put a giraffe in the same refrigerator?
Three: The king of the jungle invites all the animals to a party. Everyone comes, except for one animal. Which animal does not come to the party?
Four: You come to a crocodile-infested lake. You can't go around it, you can't go under it and you can't go over it. How do you get across?"

Stiles answered immediately, "One: We open the door, put the elephant in the refrigerator and close the door.
Two: We open the door, take the elephant out of the refrigerator, put the giraffe in and close the door.
Three: The giraffe is the only animal who doesn't go to the party because he's still in the refrigerator.
Four: You swim across the lake. All the crocodile are at the party,"

"Also, why the fuck would you ever put a giraffe or an elephant in a refrigerator?" Stiles chuckled.

Meanwhile, Derek was absolutely speechless. He'd asked that riddle to Lydia, who he thought was one of the smartest people he had ever met, and even she had to write out the whole thing and took almost half an hour to figure it out. Stiles did it in a matter of seconds.

"How do you do that?" Derek questioned, still somewhat in shock.

"What do you mean?" Stiles asked.

"How do you solve things so fast?" Derek asked, glancing over at Stiles, who had sunken low in his chair with his knees up and his worn out Converse resting on the dashboard.

He shrugged slightly, "I just hear or see stuff and it will just click into place."

"What do you mean?" Derek was confused.

Stiles shifted, "It's either common sense and logicality or... something I really don't know how to explain. When I look at someone, there are little things that my brain focuses on who they are. I can tell where they're from, where they slept last night, how many people live with them, if they're having an affair, if they're dangerous and should be avoided," he got very quiet.

Derek pondered for a moment, "that guy a month or two ago, the one in the pack from Arizona. You hesitated before shaking his hand and you didn't want any of us going near him. Did you see something that made you not like him?"

Stiles nodded, "as soon as he walked in, I got a bad feeling. The first thing I do when I meet someone is, look at their eyes. I only have to do it once and it tells me whether or not they're safe. I've been around enough monsters to know one when I see one. Most of them are human.

The moment I saw him I had the words 'narcissist, liar, and sexual predator' show up. Obviously, that last one is enough to put anyone on edge. I later talked to another Beta from that pack and she told me that he's constantly trying to get in women's beds and gets aggressive when he doesn't get what he wants. I know everyone in our Pack can take care of themselves but, I'm always going to worry. No matter what."

"Does that happen with every person you meet?" Derek asked.

Again, Stiles nodded, "yeah. Doesn't say the same thing about everyone but that always happens. Scott wasn't the first person I met in Beacon Hills but he was the first I felt okay with. We were in gym class, it was my first day at school. I didn't have a gym locker yet so I pretty much just had to sit and watch the class because I couldn't change.

I saw Scott over in the corner, lookin like he was about to drop at any moment. Eventually, Coach had some pity on him and let him sit out. He tried to introduce himself but with the asthma and all, it was just wheezing sounds," Stiles said fondly, "I saw the words, 'immature, nice, and loser' and helped him find his inhaler. I saw he had a Superman sticker on the side of it and we got into a debate on who was better; Superman or Batman and in my mind, I was like, 'this is now your friend. Stick by him, he's alright.' And since then we haven't separated."

Derek looked over to see Stiles grinning over the happy memory. He'd always wondered how the two had come across each other. Curiosity won over him and he asked the question he had been thinking about, "what did you see when you met me?"

Stiles shifted uncomfortably. "I uh... well it um, it said," he paused, sighing deeply. "It said, 'misjudged, betrayed, and... mate.'"

Derek thanked the high heavens they had reached a traffic light just as Stiles said that or he would have slammed on his brakes in the middle of the road. "You knew we were mates right from the beginning?" he asked in utter disbelief, "why didn't you say anything?!"

"I seem to recall you admitting to doing the same exact thing, just a couple hours ago," Stiles shot back, defensively.

"I thought it would keep you safe!" Derek exclaimed, growing angrier as Stiles stayed silent, pressing himself against the door as far away from Derek as physically possible. When the traffic light turned green, Derek drove forward enough to dodge the other vehicles as he pulled over to the dirt edge of the road.

"Why didn't you say anything?" Derek asked again, his tone more pointed. The boy's body was completely tensed and his scent changed to cinnamon. He was pissed. His jaw was clenched and he looked out the window, refusing to face Derek.

Very suddenly, the anger seemed to drain out. He slumped back against the chair, drawing his knees closer to himself. The scent of caramel replaced the cinnamon. Derek never noticed that particular scent until a few weeks ago. It only happened when Stiles seemed sad. He now knew it was actually him suffering from bad thoughts and memories.

Derek turned to face him. "Stiles?" he asked very gently, knowing that Stiles tended to be emotionally fragile in this sort of state.

"It was easier to cope," the teen answered quietly.

"What?"

Stiles still wasn't facing him but Derek could see a pained look from the side. "I thought you hated me," he said, "when I joined the Pack and even months after that, you acted like you absolutely despised me. It's rare that a Delta finds their True Mate. We're usually either sold off or killed before we can meet them. Sometimes, a True Mate will reject a Delta because of what they are or for some other reason.

I found out that if a Delta in a pack had a True Mate also in the pack if they were rejected, all bonds with the other members would be severed. I never said anything because I thought you hated me and if I told you and you rejected me, my bonds to the others would break. I couldn't stand the thought of that happening so I just ignored the pain and said nothing."

The guilt Derek always felt when thinking about the things he did and said to Stiles in those months hit him hard.

"Today was the first time it stopped hurting since I met you."

"What do you mean?" he asked.

"It's physically painful for a Delta to be around their True Mate but unbonded to them. Any sort of rejection, even if it isn't a full one, hurts. Anytime you said something, it felt like my Delta marking was being stabbed by hundreds of needles," he bit his lip as if trying to stop himself from saying more. "There was one day, you called me while I was at home and said, 'we don't need you. You'll just get in the way.' I wasn't even near you but it felt like someone injected acid into my veins. It hurt," he said the last part quietly as if he was shameful.

Derek felt like the absolute worst person in the whole world for making this poor kid, who had been through Hell and back, suffer even more.

Honey hazel eyes finally met his. He expected to see anger and bitterness, but there was none. "I don't blame you at all," Stiles said with a sad smile, "I know now that you were only trying to help. You never intended for that to happen. I have no reason to hold anything against you."

Derek again questioned how someone who had been so hurt, be so forgiving? "I'm so sorry. For everything I did, everything I said," he felt his chest tighten as he looked down in shame.

A soft hand laid down on his clenched fist. "Don't do the self-pitying thing. You still owe me a milkshake, and I expect lots of cuddling later," Stiles said, his usual snarkiness having fully returned in a matter of seconds. The scent of caramel dissipated, replaced by Derek's favourite fragrance: strawberries and vanilla.

Derek restarted the car, merging back onto the road before lacing his fingers through Stiles'. "As many as you want," he promised and was greeted with a wide grin.

"I will hold you to that," the boy said.

They drove the remainder of the way discussing how they would tell the Pack while the radio broadcasted an extremely overplayed song. Derek still felt some guilt lingering in the back of his mind, but Stiles had seemingly recovered from his fragile state, putting Derek's conscience slightly more at ease.

They arrived at Scott's house, surprised to see Melissa's car in the driveway. Stiles nearly fell over when the door swung open while he was in the midst of unlocking it with the key hidden in the underside of a potted plant.

Melissa stood in the doorway, arms crossed with an unhappy look on her face. "You have a lot of explaining to do," she said, waving her finger at Stiles before noticing Derek. She seemed slightly confused but moved to the side to let them enter, Stiles hanging his head in shame.

Derek was surprised by how honest Stiles was with her. He told her everything. Melissa was very visibly upset when he mentioned his relapse.

"Scott told me," she said before uttering the phrase every child had hated hearing, "I'm not mad. I'm just disappointed."

Stiles apologised over and over again but owned up to what he had done without attempting an excuse. It was one of the things Derek loved about Stiles. He knew when he made a mistake and usually admitted it. Getting out of trouble in school: a completely different story. The boy had mastered the skill of improvisation and could give a completely fabricated explanation without batting an eye and could remember exactly what he said so if questioned again, he could give the same report.

His twitching had become almost nonstop and after some more chastisement, he was freed and Melissa unlocked the cabinet for him to grab his medications. He and Derek agreed on the way to Scott's that Stiles would move in as per the requirements of assignments. They would still have to report to the town hall on Thursday and pretend like they'd never met before.

Derek had the foresight to bring the papers Melissa needed to sign and after fetching them from the car, Melissa began to fill them out. She looked up at him while Stiles was retrieving his essentials. "You'll take care of him, right?"

Derek nodded, "absolutely."

She tried to keep tears in as she finished signing the documents, handing them over to Derek. She also wrote down her number and gave it to him. "In case either of you need anything," she said and Derek accepted it with gratitude. She really was an extraordinary lady.

Stiles returned soon with his school bag and a small bag of clothing. They would be back sometime later in the week to collect his other things.

True to his word, when they left, Derek took Stiles to get milkshakes.

Chapter Text

Trigger warning for transphobia (pretty much explaining the history of Deltas) and mentions of gender dysphoria. But also a bit of SMUT in the chapter. Just a taste of what's tp come. Puns completely intended.

 

They drove around for several hours, waiting for dark when they would need to be at the school. They both knew Beacon Hills so well it was almost as if they built it themselves, so they instead went further out of town to a place Stiles had never seen.

Derek would be lying if he said he wasn't having trouble paying attention to driving while Stiles absentmindedly chewed on the straw of his milkshake. There was no sound it was more about the way Stiles' lips wrapped around it while he stared out the window, watching the world pass.

Stiles, of course, knew Derek was looking at him. The milkshake had thinned with the warmth and Stiles, knowing Derek was watching, took a sip but moved the straw in the midst, letting a drop of the white liquid roll down from his lips.

Using one of his fingers, he wiped it off and brought it to his mouth, cleaning it off with his tongue before sucking on it slightly, giving Derek a full show. Out of the corner of his eye, he saw Derek's jaw clench and his hands gripped the steering wheel so hard, his knuckles turned white.

When night began to fall, they headed back to Beacon Hills. Any confidence Stiles had gained from his little display evaporated the moment he thought about having to face Scott.

"It's going to be fine, Stiles. Relax," Derek said, catching onto the teen's anxiety.

Stiles looked at him doubtfully, "I don't know. We both take promises super seriously. I won't be surprised if he never trusts a single thing I say ever again."

"He's a werewolf. He can hear when someone lies," Derek said.

Stiles shook his head, "there's a difference between lying and breaking a promise. If I had made the promise, but fully intended on using again, that would have been a lie. I planned on keeping my word but... obviously, that didn't happen," he said, somewhat bitterly.

Pulling into the school's parking lot, Stiles hesitated to get out of the car. He took a deep breath before opening the door and stepping out, Derek at his side. They walked towards the outdoor field, Derek interlaced his hand with Stiles', giving a reassuring squeeze when they saw several of the others under the field's lights. They parted before entering the gates.

Isaac visibly restrained himself from tackling Stiles, instead, hugging him tightly. Derek watched them whisper something to each other. When they separated, Stiles reached up to run his fingers through Isaac's hair affectionately, fixing a misplaced curl. Laura informed them they had seen the creature enter the school less than five minutes before they came.

Scott, Allison, Ethan, and Danny hadn't arrived yet, so the ones who were currently there decided how to break up the groups. Once they arrived, they split into groups of four: Isaac, Cora, Erica, and Boyd; Lydia, Jackson, Laura, and Peter; Danny, Ethan, Aiden, and Kira; and Derek, Stiles, Allison, and Scott as the final group.

Before breaking up, Danny and Stiles snuck into the office, accessing the security cameras to loop their footage for an hour to hide the Pack's presence within the school.

Assigned the cafeteria and top floor of the school, Allison obviously noticed the tension between Scott and Stiles as they walked down, shooting Derek a questioning look to which the Alpha only shook his head. Her confusion only escalated when Scott pulled the younger boy into the bathroom of the cafeteria.

"What's going on?" she asked.

"They're probably talking about what happened," Derek said, trying to play dumb.

She nodded and they began to scour the kitchen with the aid of flashlights. Ten minutes later, the two boys entered, both wiping their eyes suspiciously but Derek was happy to see them standing close enough to brush against each other.

Searching the kitchen, Stiles pointed to the walk-in refrigerator for someone to check while he looked in the tray room. Scott pressed his ear against the door, listening for anything inside. Despite hearing nothing, Scott locked it anyway. Nothing seemed out of the ordinary so after a while, they made their way to the top floor.

Searching the rooms, the stench of rotten meat filled the hallways as they attempted to find the source. Derek felt his blood freeze when he heard the sound of Stiles crying out after he entered a utility closet.

Allison, being the closest one to the room, ripped open the door, pausing for a moment as Derek and Scott reached the room. Stiles lay on the ground with what looked like a mass of fatty skin on top of him.

"I would really appreciate some assistance in getting this shit off of me," Stiles said exasperatedly as he tried to push the skin away.

The stench of the rotted meat had Scott gagging while Derek pulled Stiles out from underneath. The teen was covered in blood and other unmentionable fluids, his clothing completely ruined. The flesh on the ground began to bubble alarmingly and they managed to slam the door shut before the sound of a small explosion echoed through the hallway.

Waiting a moment before opening the door again, the splattered mess began to seemingly evaporate, smoking and hissing. In a matter of seconds, all that was left was Stiles' flashlight on the ground.

The remains covering Stiles did not do the same and the teen disappeared into the bathroom to try and clean it off as much as possible. A very grumpy Stiles emerged several minutes later, clothes soaking wet from the sink.

Thankfully, he hadn't been wearing his beloved red sweater but lifting his leg he shouted, "IT BURNED A FUCKING HOLE IN MY SHOE!"

Looking over, it had indeed burned a hole right through the sole of his Converse. "Of course, of fucking course. Its gotta eat through fucking rubber. Won't go through steal no, no its gotta go through RUBBER. Great!" he stomped his foot, pouting like a petulant child and slapped Scott's shoulder when the Beta laughed.

"You don't smell though, so that's good," Scott said, trying to pull himself together.

Always one for innuendoes, Stiles tugged on his drenched shirt saying, "I'm wet and NOT IN THE GOOD WAY." He huffed, still pouting, "at least we can go home now."

"We still have a couple minutes though. And, now we know it's here," Allison said.

Stiles shook his head, "that's what happens when it dies. It turns into a pile of skin and breaks down. Unless it had babies or something, which I highly doubt because it only lays eggs in salt water, we're done and don't even have to clean up," he paused, looking down at himself, "well... I have to clean up."

Sending a quick text to the other groups, they started on their way back to the field, Stiles complaining the whole time. He groaned when they reached the gravel patch, not wanting to walk over it with his dysfunctional shoe.

Having pity on the boy, (and also just trying to get him to stop whining) Derek picked him up, carrying him across and grimacing as his own shirt got wet. He felt proud when Scott smiled at him, satisfied that his best friend was being treated kindly.

Stiles frowned when Derek placed him down again as they neared the field, but gave him a small peck on the cheek to show his appreciation.

"Had a good time, Stiles?" Jackson asked, taking in the younger boy's ruined clothes.

"Abso-fuckin-lutely," Stiles said with an extremely fake cheery smile, "can't you tell how damn happy I am?" he asked, through his clenched teeth.

Sharing information, Ethan stated they had found a trail of destruction in the locker room that they straightened up and Danny had gone ahead without Stiles and wiped the footage from every camera to hide evidence of anything ever happening.

Derek hadn't noticed the temperature had dropped until he felt Stiles shivering next to him. Not surprising considering his clothes were damp. Derek held his arm out, creating a space for the teen to huddle close against him, drawing several looks from the others.

Peter, the bastard, had an amused look on his face as he tried (and failed) to suppress a smirk. Derek remembered what Stiles had said about Peter, betting on them and he gritted his teeth.

He didn't want his damn uncle to get that money.

The Pack parted ways again, this time heading to their own homes and calling it a night. Stiles' teeth began to chatter as he and Derek walked back to the car, leading the 'wolf to blast the heat, despite his own discomfort.

Music played on the radio and Derek could see Stiles moping, staring sadly at his destroyed shoe. "We'll get you a new pair tomorrow, after school. You brought another pair from Scott's house so you're good until then," Derek said.

Stiles slumped in his chair, groaning loudly, "UUUUUUGGHHH."

Derek looked over at him, eyebrows raised, "problem?"

"Do I have to go?" Stiles whined.

"Yes, you have to go. You missed today, I'm not gonna let you fall behind in class," Derek said.

Stiles snorted, rolling his eyes. "What?" Derek asked, trying to keep his tone cool. He hated when someone rolled their eyes at him.

"There are very few things I'm actually good at; academics is one of them. I skip all the time, but I've gotten perfect scores on every test, every essay, I turn in my homework, I don't need to be there," Stiles said.

Derek listened for any sign of a lie, but couldn't find one. If Stiles had said this when they first met, he wouldn't have believed it. Now, it didn't surprise him. The kid was smart as Hell. "You're going tomorrow, Stiles," Derek said absolutely. He wasn't about to let his attendance slip anymore.

Stiles realised quickly it was futile to argue on this topic and sulked all the way home.

Entering the House, Stiles turned to Derek. "Can I take a shower?" he asked. The tone of his voice sounded like he expected Derek to say no.

"Of course," he said, leading the boy up to their bathroom and showing him the controls for the temperature of the water before leaving him be.

Derek remembered what Stiles said about Deltas being "self-cleaning" but he didn't blame the teen for wanting a shower after his encounter with shlopped off skin. He realised it was a perfect time to actually do his research on Deltas. He hadn't had the chance to do it before.

Returning to the living room, he started to search information on his computer. As he read, he began to think Deltas were probably one of the most interesting and, certainly, the most tragic beings in the world.

'A Delta can anatomically change their biological sex at will. A Delta presenting as a male may choose to possess female genitalia despite already having a uterus, as all Deltas do. They may choose to be hermaphroditic or "intersex" possessing characteristics of both male and female genitalia. Many Deltas suffer from gender dysphoria and feel abnormal compared to the rest of the population.

The unfortunate history of persecution has undoubtedly influenced this idea of isolation. Viewed as abominations by many, Deltas tend to hide their identities out of fear of prejudice. Several claim public situations are emotionally and psychologically exhausting. The constant paranoia of being found, force many to avoid social interaction.'

Derek wondered for a moment if maybe this contributed to Stiles' anxiety of socialising. The article went on to talk about how Deltas are more likely to suffer from mental illness, almost seventy-eight percent being diagnosed with some form of depression.

'Many believe a Delta's sole purpose in life is to please an Alpha and bear children. Occasionally, if mistreated or abused, a Delta will rebel against their natural instinct to submit. It is physically painful to do so. There have been five documented cases of a Delta resisting a Dominant's Voice.'

Looking back on the fight Stiles had with the Alpha, Jason, Derek wondered if it hurt Stiles to refuse to sit down. He couldn't help but feel proud of the boy, who refused to give into an order to do something he didn't want to do, against his very nature.

Reading on, the article explained the history of Deltas in depth, describing in gruesome detail the horrors of the near genocide they faced. It sickened Derek to think about it. It always confused him as to why someone could be viewed as "less than." Racism and sexism baffled him in school, to the point where he took a psychology course in college in an effort to understand the reasoning behind it.

It still confused him to this day.

Nearing the end of the article, it took a very sudden turn. It began to explain the bodily functions of a Delta other than their ability to change their sex.

Before he could read it, Stiles entered the room, hair damp from his shower. He wore pyjama pants the donned several comic book-style exclamations like 'BANG' and 'POW.' Derek found his geekiness adorable and then he realised Stiles was wearing one of his shirts.

"I hope you don't mind. It looked comfy and it smells like you," he said.

Derek decided he wouldn't mind if Stiles wore every single article of clothing he owned. The sight of it on him had his wolf howling with possessiveness. It was too big for Stiles, the sleeves passing his hands and the hem of it reaching his thighs and Derek loved it.

Noticing Derek's reaction, Stiles smirked, spinning slowly to give Derek a bit of a show. "Like it?" he asked smugly.

Clenching his jaw, Derek looked away and said, "I'm gonna make dinner. Are you okay with chicken?"

Derek might have been misreading but Stiles seemed somewhat disappointed. "Yeah, sure. Chicken's fine," he said flatly.

"You still have homework, right?" he asked and Stiles grimaced, nodding. "Come to the kitchen table and do it while I make dinner," Derek said.

While cooking, Derek glanced over at the teen frequently. It was no secret that Stiles was easily distracted so it didn't surprise Derek to see him looking around the room or trying to fix the bent ring of his school binder. What did surprise him was all the while Stiles wasn't paying attention, he never once stopped writing.

The boy was looking down at something in his lap and Derek practically snorted when he realised, Stiles was watching a video on his phone.

"I thought you were supposed to be doing homework," Derek said, making the teen jump.

"I am," Stiles replied curtly, waving his paper in the air without looking at him.

"You can't watch a video and do homework at the same time," Derek said, eyebrows raised at the sharpness of the response.

"(I) can watch a video and do homework at the same time. I read the questions, I know the answers, I can write without focusing on it," he said dismissively.

The Alpha part of Derek did not like the attitude, but he kept himself under control and instead took the paper from the boy's hand. He was absolutely shocked to find the handwriting was immaculate; perfectly straight on the lines and even, despite Stiles not even looking at it while writing.

Derek had taken a Forensics class in high school, during one of the units, they analysed handwriting. The way Stiles wrote his 'g's and 'y's were typically feminine but the consistency in his lettering was amazing.

In flawless cursive, Stiles gave incredibly detailed and in-depth answers. The flow of his words made Derek wonder if Stiles was a writer. It would make sense considering his wording of his responses.

Looking up at the teen, Derek was faced with pursed lips and a raised eyebrow, the typical look for Stiles when he was not in a good mood and someone was bothering him. It irritated Derek somewhat but it didn't take away from how blown away he was.

"You are absolutely amazing," he said, and Stiles' challenging look disappeared, being replaced with a bright blush.

Handing the paper back and returning to cooking out of concern of burning it, Derek continued to keep an eye on the boy as he worked through assignment after assignment with little difficulty. He had forgotten that Stiles was moved up a grade and it made sense to him now as to why that was.

Finishing dinner, Derek served it and they sat together watching the video Stiles was watching. Derek was the one not paying attention now, instead, he was focusing on how his shirt draped the teen's shoulders.

Stiles most likely noticed his staring as he stretched in his chair. He was surprisingly flexible, back stretching elegantly and arms extended, head leaning back to expose his neck. Pretending like nothing happened, he returned to the video.

Derek was getting frustrated, the constant flirting and the fact that Stiles was covered in his scent was testing his self-control. He was struggling against his wolf and instinct to mark and claim and the frustration was building.

Once the video was over, they cleared their plates, Stiles immediately washing the dishes, shooing off Derek when he tried to help, claiming since Derek cooked he should do something in return.

The domesticity of it all felt foreign to Derek. His past relationships (after Kate) never lasted more than two or three months. For nearly a year before he met Stiles, the thought of living with a partner was not appealing. Now, the idea of waking up next to Stiles was something he wanted.

The teen entered the living room a couple minutes later, sleeves rolled up to prevent them from getting wet. Turning on a movie, Stiles climbed onto his lap.

Derek quickly realised that's something Stiles did quite often. He liked to sit in people's laps. Derek had seen it with Scott, with Isaac, with Danny, even Allison and Lydia (who didn't seem to mind at all.) They just accepted it without complaint and let him stay.

Seeing Stiles sitting in PETER'S lap made Derek nearly lose his shit as his uncle just winked at him and held onto Stiles' waist, pretending he was trying to prevent him from falling. Peter's lap seemed to be one of Stiles' favourite laps to sit in but now he had a feeling it was just to make him jealous.

It fucking worked.

The teen resting against his chest shifted, snuggling closer and bringing Derek back to the present. He continued to shift, trying to find a comfortable position. Derek had to grip the boy's hips to keep him in place, trying to suppress his "problem."

Obviously, Stiles knew exactly what he was doing and Derek found himself being straddled, honey hazel eyes blown wide flickered from his eyes to his lips. Kissing him roughly, Derek pulled Stiles in closer, revelling in the little gasp he drew out of the teen by biting his lip.

Stiles rocked his hips, grinding down and moaning softly against his mouth. The teen slid out of his grasp, dropping to his knees between Derek's legs. The werewolf growled as Stiles mouthed at the clothed bulge in his jeans.

"Can I, please?" Stiles asked, reaching for the fly of Derek's trousers. With a nod of approval, he unzipped him, nimble fingers dipping down and pulling Derek's restrained erection free.

His eyes widened as he was faced with Derek's size. His hand barely wrapped around it, only connected by the very tips of his fingers. Looking up at Derek, he asked, "how the fuck do you find pants that fit?"

Derek snorted, "with great difficulty," he said, taking one of Stiles' lines.

Stiles chuckled as he licked a stripe along the underside of his cock, following the thick vein. Wrapping his lips around the head, he ran his tongue over the slit, earning a groan from the older man.

Taking an inch more into his mouth had Derek running his hand through Stiles' hair. "Don't choke yourself," he said.

The teen looked at him, raising an eyebrow and a look in his eyes as if he'd just been challenged. It confused Derek for a moment until he nearly had a brain aneurysm when Stiles suddenly took him entirely down his throat, all the way to the base without a single gag.

Stiles began to bob his head, letting out a moan when Derek fisted his hair, sending vibrations that made the 'wolf jerk. Stiles suddenly stopped, through his lashes, he looked up at Derek innocently.

He tilted his head, leaning into Derek's touch and tapping his thigh. It took Derek a moment to realise Stiles was letting him take control.

He fucked into his mouth, making Stiles jolt forward to support himself by holding onto Derek's thighs. He somehow managed to continue sucking while Derek thrust roughly, growling. He slowed down occasionally to appreciate Stiles' lips stretched around his cock before returning to his punishing pace.

Stiles' brows were furrowed and his eyes watered, he didn't gag but no doubt his jaw ache. Werewolf stamina. Derek pulled him off every now and again to let him quickly catch his breath.

Feeling himself getting close, he tried to pull Stiles off again but instead, the teen shook his head, bobbing up and down, sucking hard. Derek came with a snarl, Stiles swallowing every bit of it. Leaning back, Stiles was breathless as he tucked the werewolf back into his jeans.

Derek yanked the boy onto the couch, pinning him down and attacking his neck. He blushed bright red, shifting underneath him before keening when Derek slid a hand down his pyjama pants, wrapping a hand around him.

It didn't take long to push Stiles over the edge with Deltas being far more sensitive than normal people. The teen shouted, back arching and let out a high pitched whine as his whole body shivered.

The scent of strawberries and vanilla filled Derek's senses and he nuzzled against the younger's throat, kissing the marks he sucked into the smooth skin.

"You okay?" Derek asked. Stiles nodded, looking not quite fully present. "Let's get you cleaned up and changed," Derek said.

"Um," Stiles blushed, voice hoarse, "don't need to." Avoiding Derek's confused look, Stiles continued, "Deltas don't have a need for that kind of stuff. We don't produce... uhn, yeah."

Derek snorted, Stiles was cute when he blushed. Even more so with his hair dishevelled and his lips, a dark red colour. Lifting the teen up, he carried him to their bed, making sure to lay him down on the side that wouldn't hurt his shoulder.

Stiles whined when Derek let go of him to strip off his clothing, making him chuckle. Climbing into bed, Stiles immediately curled against him, revelling in the body heat of the werewolf.

He fell asleep quickly, faster than any other occasion he could remember. Derek carded his fingers through the sleeping teen's hair, double checking his alarms were on so Stiles would wake up for school. He was definitely going to be dealing with a lot of complaining but, he didn't mind.

Stiles would probably be exhausted tomorrow. He'd had three emotional breakdowns in the same day. One during Derek's confession, another in the car with his own confession of knowing they were mates (though he managed to keep himself from crying) and the third being the heart to heart with Scott at the school that he still needed to ask Stiles about.

He was just happy the two seemed as close as they were before: as close as brothers.

Derek was absolutely going to spoil him tomorrow when taking him shopping. Stiles was notorious in the Pack for refusing to let others pay for him. It surprised Derek he even allowed him to buy the milkshake. There was bound to be some resistance, but Derek wasn't gonna let that stop him from pampering the boy.

Lord knows the kid deserved to be coddled after everything he'd dealt with and Derek was Hellbent on making that happened
