"You're pregnant, Alexander." Magnus breathed.

"I'm what?!" Alec exclaimed, visually panicking. Magnus couldn't blame him, he'd be freaking out if someone had just told him that he was pregnant.

"Pregnant." Magnus confirmed. Alec lay back on the bed, curling into Magnus' side.

"I'm too tired to process this now." Alec admitted. "It's just making me feel scared. And there's so many other things going on too. We'll talk in the morning." Alec leant up to kiss Magnus before burying his head in the side of his boyfriend's  neck and drifting off to sleep.

Magnus was glad that Alec had been able to fall asleep without too much trouble. He, on the other hand, wasn't going to sleep any time soon. Magnus was too in awe of the discovery that he could be a father. It just strengthened his love for Alexander. He would go to the end of the Earth to protect his newfound family.

Having wanted this for a long time, Magnus wasn't going to let anything get in his way of this miracle.

Chapter Text

Despite his lack of sleep, Magnus felt wide awake. He couldn’t help a huge grin from braking out on his face due to the life changing revelation that had come to light less than 10 hours ago. He was going to be a dad! Something he had always wanted but had never known was possible.

Alec was gently woken by the repetitive motion of Magnus rubbing circles on his currently flat stomach. A smile formed on his face and he placed his hand over Magnus’, stilling the hand and linking their fingers.

“Hello.” Magnus greeted.

“Hi.” Alec smiled back, shyly. Then his stomach gave a horrible lurch and he threw up all over the bed. Alec coughed, allowing the contents of his stomach to empty over the bed and himself as Magnus rubbed his back.

Magnus waved his hand and the mess was gone. At least now Alec knew why this had become a regular occurrence over the past few days. “I need a shower.” Alec declared. Magnus couldn’t blame him. Alec quickly got up and walked over to the bathroom, Magnus followed after not too long. After the shower, they needed to have a discussion about what the future was going to hold.


Alec found the shower to be very relaxing. Having Magnus there made him feel better, it stopped his mind from wandering towards the terrifying. Once they had finished showering and had gotten dried, Alec started getting dressed whilst Magnus continued to laze around Alec’s room in his towel. “Right, there are some things we need to discuss.” Magnus stated. Alec moved to sit on his bed beside Magnus, before nodding in agreement. “Tell me how you’re feeling.” Magnus requested. Alec let out a long breath.

“I’m scared.” Alec whispered. Magnus took the Shadowhunter’s hands in his and wrapped the other arm around Alec’s shoulders.

“That’s understandable, but we’ll do this together. I’m always going to be here for you, that won’t change.” Magnus explained. Alec looked near tears.

“Thank you. I’m so scared. I didn’t know this was possible. How did it happen?” Alec asked, leaning his head against his boyfriend’s shoulder.

“I don’t know. But it’s not my area of expertise so I shall have to call in a favour from a friend.” Magnus replied.

“I need to finish getting dressed before I leave this room and begin my day of work. I don’t know what’s going to happen now, in regards to my pregnancy or Jace leaving with Valentine.” Alec stated.

“We’ll figure it out. I need to return home now anyway, I have clients to see and a friend to talk to. I’ll see you soon. I love you, Alexander.” Magnus said.

“I love you, too, Magnus.” Alec replied, pressing his lips to Magnus’.

Now he just had to try and continue as normal. Allowing someone the knowledge that things were different could prove to be dangerous.

Alec did try to go about his day like normal, it wasn’t easy, what with this new discovery but he managed. Until everything turned towards Jace. Even though it had only been a matter of hours, any mention of his parabati filled Alec with dread.

But Alec was becoming more and more restless with all the lack of progress. Magnus had arrived not too long ago after Izzy had texted him to alert him about Alec’s agitation. So, the Warlock had joined in and was now using his magic to try and track Jace. Unfortunately, like everyone else, he wasn’t having any luck.

“Any word from the Clave?” Izzy asked.

“Not yet. And we’ve been trying for the past four hours. Something’s up.” Lydia replied as they walked into the Ops Centre.

“Mmm, the Clave being unhelpful? Who’s shocked? Show of hands?” Magnus joked.

“I’m worried. I can’t sense Jace through our parabati bond.” Alec told them.

“We’ll find him, Alexander.” Magnus assured.

“When we arrested Hodge, he said Valentine was on a ship. They must still be over water.” Izzy predicted.

“Pull up the waterways around New York.” Lydia instructed. So Izzy did.

“The ship couldn’t have gone too far.” Izzy assumed.

“Anything?” Alec asked, looking at Magnus who was trying to track Jace by using one of his hoodies.

“Sorry.” Magnus replied.

“There’s got to be something!” Alec exclaimed, both his emotions and his hormones threatening to get the better of him. Magnus raised an eyebrow.

“I don’t see him.”


“All right, listen up.” Alec announced. “I want 24/7 monitoring of the Hudson and East rivers. If you see anything unusual, you come to me first.”

“I’ve got this, Alec” Lydia stated.

“Then why haven’t you found Jace yet?” Alec barked in response.

“Don’t forget who you’re talking to. I am still the head of this Institute.” Lydia asserted.

“And my brother is still missing!” Alec argued.

“Why don’t you just take a break?” Izzy advised.

“Not now, Izzy.” Alec brushed her off.

“Isabelle’s right and it’s not a request. You’re dismissed.” Lydia ordered.

“Fine!” Alec went to storm off but Magnus caught his arm.

“Hey…” He soothed but Alec pulled his arm free and spun around to face the small group.

“Everybody, just back off!” Alec declared before leaving the room. Magnus was shocked.


Alec had gone up to the roof of the Institute for some fresh air. He also knew that he needed to try and get his emotions under control because he kept snapping at the people he cared about. That was where Magnus found him.

“I’m sorry for how I reacted before. It’s not personal.” Alec apologised.

“I get it. I’m a lot to get used to. I know what you’re going through, Alexander.” Magnus sympathised.

“No, I… I don’t think you do.” Alec stammered. “Jace is a part of me. Through a rune, we are both physically and emotionally connected. If he dies, a part of me dies, too. And he’s in trouble out there and there’s not a damn thing I can do about it.” Alec ranted before trying to walk away again. Magnus sighed.

“Tell me what I can do.” Alec turned back to Magnus.

“Help me track Jace. I want to use our rune. I just need your magic for the pain.” Alec requested.

“I can’t help you with this.” Magnus refused.

“Why not?” Alec demanded.

“The last time you tried to use your rune to track Jace, it almost killed you.” Magnus began.

“Why can’t you just do this one thing? After everything I’ve done for you.” Alec shouted before leaving. Again.

Magnus stayed on the roof for a while, trying to keep his emotions in check and not get angry. He could understand why Alec was so worried, it was to be expected. But Magnus wasn’t going to be able to forgive Alec easily for this. With the day’s events, Magnus could understand if last night’s discovery had been pushed to the back of Alec’s mind and he had forgotten. But Magnus hadn’t. And he wasn’t willing to do anything that could put their little miracle in danger until he’d spoken to Catarina.

“We are at war.” Maryse declared to all the Shadowhunters stood before her in the Ops Centre. “Valentine now has the Mortal Cup, with which he is no doubt raising a new army… and one of our own had joined him.”

“Looks like the queen’s taking back her kingdom.” Izzy muttered.

“As a result, the Clave has declared a state of emergency at the Institute. Their first priority is to replace the current leadership, whom they have deemed wholly ineffectual. It is an honour to introduce the newly appointed head of the New York Institute, Clave representative, Victor Aldertree.” Maryse concluded before she stepped down to stand with the other Shadowhunters.

“Did you know about this?” Alec asked Izzy.

“No. But maybe this is why Dad went back to Idris.” Izzy suggested.

“Maryse went behind my back.” Lydia commented.

Back at the front of the room, Aldertree stepped forwards to address everyone. “My fellow Shadowhunters. It is an honour to be here with you all. We have to find Jace Wayland. He’s a Shadowhunter and we don’t leave our people behind. The answer to his location may very well lie in this room. So, I wanna speak with everyone who went on the mission where Jace disappeared. One last thing. Effective immediately, this Institute is on lockdown. But it’s only temporary. Let’s turn the Institute around.” He explained before leaving, allowing everyone to disband.

“Wait, if we’re on lockdown then who’s out there looking for Jace?” Clary asked, turning to Izzy.

“We’ll think of something. Don’t worry. Jace is tough. Valentine will never break him.” Izzy assured.

As Alec was checking one of the monitors, he saw Magnus heading to the entrance of the Institute out of the corner of his eye. “Hey! Hey!” He called. Magnus stopped and turned to face Alec. “Are you going home?” Alec asked.

“Where else would I be going? My interview’s over and I’m exhausted. Besides, at my house, there’s steak and vodka.” Magnus responded. “I’d rather be there.” He added before turning to the doors again.

“Wait, you’re just… You’re not gonna help?”

“You really don’t get it, do you?” Magnus asked. “You didn’t risk anything for me, you did it for you.”

“What? Are you seriously doing this right now? Right now?” Alec shouted.

“You know damn well that I want to find Jace just as much as you do, but that’s no excuse to treat me like-”

“Well, then, what do you want from me?” Alec interrupted. Magnus took a deep breath.

“At the moment… nothing.” Magnus breathed. Before Alec had the chance to reply, the Institute’s alarms started blaring.

Alec was torn between trying to talk to Magnus and going to find out why the alarms had been sounded. In the end, the choice was made for him as Magnus left without another word.

“Who sounded the alarm?” Alec asked as he returned to the Ops Centre. When he got there, he was terrified to see a hologram of Jace with the words; ‘wanted dead or alive’ written across it.

“What’s going on?” Izzy asked as she entered the room.

“Oh, no.” Clary breathed. “Jace… Aldertree said he wanted to rescue Jace.” She claimed.

“Actually, Clary, I said I wanted to find him. And you gave me the clue that I needed to do just that.” Aldertree corrected.

“What did you tell him?” Alec asked Clary, seething with anger.

“Alec, it-” Clary tried.

“Is this everyone?” Aldertree announced.  “Fantastic. First up, all Downworlders are forbidden from entering the Institute without my prior approval. For those still present, good day. Mr Graymark…”

“I’m not leaving Jocelyn.” Luke argued. “Besides, my badge gives me access to resources that you don’t have. I can help you find Jace.”

“That’s generous of you, but I’m going to have to insist.” Aldertree smirked.

“Call me when you can.” Luke told Jocelyn. She nodded

“You too… Simon. Simon, right?” Aldertree requested.

“It’s almost dawn.” Simon defended. “I don’t have anywhere to go.”

“Hey, you’re a smart guy. I’m sure you’ll figure something out.” Aldertree responded, clapping Simon on the shoulder.

“Simon, come on.” Luke urged.

“I’ll be okay.” Simon whispered to Clary before leaving with Luke.

Aldertree clapped. “Now… let’s get to it. I’ve reviewed your statements along with the reports of your unsanctioned missions. And I can come to no other conclusion than the fact that Jace Wayland is a traitor to the Clave.” Aldertree announced.

“Jace is not a traitor.” Alec protested.

“Point of fact. Clary said that Jace called you to warn you about Valentine’s trap which got me thinking… Jace had multiple chances to kill Valentine, but chose to let him leave. Now, Valentine, Jace and the Cup are missing. Do the math.” Aldertree explained.

“There is no way we’re going to help you hunt Jace.” Clary stated.

“And I’d never ask you to. You and your friends are prohibited from any further involvement in the hunt for Jace Wayland.” Aldertree ordered.

“What?” Izzy asked, shocked.

“The rest of you, back to work. I’m lifting the lockdown on the Institute, except for Clary and Jocelyn. Given your relationship to Valentine and Jace, I want to keep a close eye on you.” Aldertree then walked away.

“This is ridiculous.” Clary claimed.

“Clary-” Jocelyn began.

“No! We cannot just sit around. Okay, they’re going to kill Jace. He’s your son.” Clary argued.

“I know you think you understand this world, but you don’t.” Jocelyn told her daughter.

“Dismissed.” Aldertree shouted.

“You can’t do this.” Alec insisted.

“See, that’s the thing about being the boss. I can and I did.” He replied.

“Then revoke the dead or alive order. Jace is one of us.” Izzy added.

“Challenging the authority of the head of the Institute is grounds for severe punishment, including de-runing.” Aldertree threatened before he actually did leave.

Chapter Text

Alec knew that he owed Magnus the biggest apology ever. Not only did he devalue his boyfriend, and how much Magnus actually meant to him, in his anger and worry, Alec completely forgot about his newly discovered pregnancy. And then he’d asked Magnus to help him do something that could kill their baby. He needed to go and apologise now, before it became too late.

Unfortunately for Alec, he had just gotten to the bottom of the steps leading away from the Institute when he heard “Alec!” being called sternly by his mother. “Alec, slow down.” She instructed. He stopped and allowed Maryse to catch up with him. “Where are you going?” She inquired.

“Magnus’.” Alec replied. “I couldn’t just sit in there and not do anything. He’ll help me find my brother.” Alec expanded.

“Jace is not your brother. He’s not your blood.” Maryse responded.

“He’s closer than blood. He’s my parabati.” Alec defended.

“Alec, we looked like fools taking in Valentine’s son, caring for him like our own.” Maryse tried.

“It was the right thing to do.” Alec claimed.

“It was a mistake.” Maryse disagreed. “It put our family in danger.” Maryse pulled her eldest in for a hug. “You need to forget about Jace. He made his choice.” Alec pulled away.

“Do you ever hear what you’re saying? If you kill him, you kill a part of me.” Alec argued.

“When you have a cancer, you cut it out before it destroys you. Son… life is full of hard choices.” Maryse defended, Alec scoffed.

“Don’t kid yourself. You’re not making a hard choice. You’re saving your own ass. And, unlike you, I don’t push someone away just ‘cause they’re a hard choice.” Alec countered before walking away.


Once he returned home, Magnus tried to go to sleep, but he was too wound up to settle down. His first task that day had been to contact Catarina. Even though things with Alec were slightly rocky at this moment in time, Magnus was always going to put the two of them first. Their baby and his number one priority.

After contacting Catarina, who said that she would be more than happy to check up on a friend of Magnus’ throughout their pregnancy, Magnus needed an out let for his pent-up energy. So, he went to the balcony to calm down in an environment that would be okay if his magic flared. This was how Alec found him.

When he reached Magnus’, Alec just let himself in. Magnus could sense his presence immediately but carried on working with his magic, leaving Alec to make the first move. “Magnus. I’m not good at apologies… but I’m… I’m sorry.” Alec stuttered.


“I’m… really sorry.” Alec added.

“For?” Magnus asked.

“Look, can you just cut that out for a second?” Alec requested. Magnus released the ball of magic, which then went flying behind him and nearly hit Alec before crashing into a lamp. Magnus raised an eyebrow. “You were right. When I called off my wedding, that was for me. But this is all just… It’s new to me, and I find myself getting lost and confused.” Alec explained.

“This may surprise you, but you’re new for me too.” Magnus responded.

“Look, with Jace missing, it’s just like… the ground has shifted and I can’t keep my balance. And then to discover that I have a life growing inside of me. Just… I didn’t mean to take it out on you. I’m sorry.” Alec concluded, close to tears.

“You’re forgiven. Also… you’re great at apologies.” Magnus smiled as he adjusted the collar on Alec’s jacket. Alec looked away, blushing.

“Thanks. I’ve been working on it.” He admitted.

“Here’s the thing… we’re always going to face challenges. Especially with a baby on the way, so, when things get crazy, don’t push me away.” Magnus requested. Alec nodded as Magnus pulled him into a kiss.

Chapter Text

Magnus and Alec were curled up together on the sofa decided to broach the subject. “My friend, Catarina, is a healer. She’s the one I’ve called in the favour from, and Cat is more than happy to oversee your pregnancy.” Magnus informed Alec.

“Okay. Thank you. How much does she know?” Alec asked.

“Just that one of my Shadowhunter friends is pregnant and I would like her help.”

“How soon can she come and check that everything is okay? When I remember that I’m pregnant, I become terrified. I don’t know what I’m doing. When I imagined having children, I definitely wasn’t the one who ended up pregnant!” Alec ranted.

“I’ll give her a call now, and see when she’s free.” Magnus told Alec before getting up off the sofa to grab his phone and go into the bedroom.

Catarina picked up on the fourth ring. “Hello, Magnus. What can I do for you now?” She asked.

“I was wondering how soon you would be able to come over and check over my friend and the baby.” Magnus explained.

“I’m free right now, if that’s any help.” Catarina offered.

“That would be wonderful, thank you.”

“I’m going to bring a helper. You’ll understand soon enough.” Catarina told him, cryptically. Although Magnus may have had a clue as to who she was talking about. “I’ll be with you shortly.” Catarina confirmed before ending the call.

It was then that Alec ran into the room. “I can sense him. He’s on land.” Alec exclaimed.

“Catarina is on her way. But she can wait, this is important to you, and your health does have an effect on the baby. Go and find your parabati, we’ll be here when you get back.” Magnus responded, smiling fondly at his boyfriend.

“Thank you.” Alec then pressed a chaste kiss against Magnus’ lips and then he left. Magnus chuckled. He loved Alec, so very much.


Alec went straight back to the Institute. He needed to try and convince Aldertree that he was the one who should go and get Jace. “Jace is back. Call off your men.” Alec requested as he followed his sister into the Ops Centre. “Izzy and I will bring him back alive.”

“One step ahead of you. We got a hit on the map. We’re mobilising now.” Aldertree replied.

“You’re not listening. Go ahead and de-rune me. We won’t let you do this.” Izzy argued.

Aldertree indicated to his men. “Hold them here until we get back.” He instructed and several people surged forwards and grabbed hold of the Lightwood siblings. Aldertree then walked away.

“I’m sorry. I’ll do whatever I can to help Jace.” Lydia promised before following Aldertree. Maryse followed after too, without saying a word to either of her children.

Alec and Izzy were then manhandled to their rooms, and the men stayed to guard their doors. Alec whipped his phone out and sent a text to Magnus.

Aldertree has me being held at the Institute. There are guards at the door but none in my room. Please can you come and get me? I love you. Alec.


Catarina arrived maybe ten minutes after Alec had left and her helper was none other than Tessa Gray. After Will had died, she reverted back to her maiden name. Since Magnus had been so helpful to her in the past, she felt as though there must’ve been something she could do to help him. And Catarina provided the perfect opportunity.

The three Warlocks spent twenty minutes just catching up with each other and reminiscing about the past before the conversation changed and Tessa decided it was time to grill Magnus about the reason they were there in the first place. “So, Magnus, are you going to explain to us exactly why we’re here?” Tessa asked.

“Something to do with a pregnant Shadowhunter isn’t much help.” Catarina added. “As I’m sure they have their own healers to deal with pregnancy.”

“It’s a bit more complicated than that.” Magnus commented. The women looked at him expectantly. “I’ve started seeing someone.” Magnus revealed. Both Catarina and Tessa looked at him in shock before getting over it quickly.

“That’s amazing.” Tessa squealed, surging forwards to give Magnus a hug.

“Are you going to give us anything else to go on? Or do I have to spike your drink with a truth potion?” Catarina asked. Tessa laughed.

“He’s a Shadowhunter.” Magnus began.

“You’re dating a Shadowhunter?!” Tessa exclaimed. “I never thought I’d see the day.”

“And we don’t know how, but he’s pregnant.” Magnus added.

“And it’s yours?” Catarina asked. Magnus shot her a dirty look. “I have to ask! Warlock’s can’t have children, so how is he pregnant?”

“He was a virgin when we met.” Magnus countered. “And I don’t know how! He’s so shy. I’ve made most of the advances.”

“I’m sure you would’ve made most of the advances anyway.” Tessa commented.

“Most people are considered virginal when compared to you!” Catarina joked.

It was then that Magnus’ phone chimed, alerting him to a text. “Is that him?” Tessa asked, quite eager to meet the man that could have this effect on their friend.

“Yes. I need to Portal him here. They’ve trapped him at the Institute. All he wanted was to help find his parabati.” Magnus replied.

“At least tell us his name before he arrives.” Tessa begged.

“Alec Lightwood.”
