Peter pales when he sees it. Why is his Papa even here right now?! He and dad are supposed to be meeting at that fancy restaurant in half an hour. But there he is, kissing some random person Peter has never seen before, trying to push him out the door.
“I love you, Buck, but I really do have to go.”
‘Buck’ pouts. “You should just leave him. Come with me, take Peter with you!”
“He’s 16, not 6. He won’t want anything to do with me if he knows about you. Now go, I’m not leaving Peter.”
He watches the mystery person leave, getting into a very old looking car.
Peter doesn’t know what to do. He doesn’t want to believe his Papa is a cheater! But he is, so he has to tell his dad… but… should he talk to Papa first? Maybe… maybe he can convince his Papa to stop seeing the mystery boy…
But his dad deserves to know, even if Papa does stop seeing him. Ah, he doesn’t know! He watches his Papa leave, off to the restaurant he’s sure.
Well, Peter has all night now to figure it out…
He decides to go to his Papa first. He waits for his dad to go to the lab, knowing he won’t be able to hear; then corners his Papa.
“I saw you. Last night.” He says, looking completely angry.
Steve freezes, then slowly lowers his coffee cup. “I’m not sure what you’re talking about.”
Peter glares at him. “I’m talking about your affair.” He spits.
Steve pales. “Shh!” He looks around, obviously scared. “That wasn’t what it looked like!”
“Oh? So you didn’t have your tongue down someone else’s throat?”
Steve winces and backs up. “D-don’t, dont Tell your dad. It was a mistake- it was-“
“You said you love him. You said you love him!”
Steve is obviously panicking now. “Please don’t tell Tony, I’m sorry, please-“
“You tell him, tonight, or I will. Understood?”
Steve bites his lip and nods, looking terrible right now.
Good, Peter thinks.
The night ends and Steve is sleeping in bed with Tony, so Peter knows he didn’t do it. Which is just great, he always wanted to see his dad’s heart break in front of his very eyes. Woo.
“Dad? I need to talk to you.”
Steve springs to his feet. “No you don’t, you need to get ready for school.” He insists.
Peter glares. “I think you should sit down, now.” His voice leaves no room for argument.
But of course, Steve argues anyway. “That’s no way to talk to-“
“Either shut up or leave the room, Steve, I’m tired of your bullshit.” Peter seethes.
Tony’s eyes widen. “That is no way to speak to your father! What on earth has gotten into you?”
Peter stares Steve down, who breaks eye contact and sulks to his room. Probably to pack his bags. Peter hopes so anyway.
Peter sighs and looks to Tony, going closer. “Dad… I have really bad news…”
Tony frowns. “It must be bad, for you to be so disrespectful…”
Peter sighs and rubs his eyes. “I saw Papa cheating on you. He said he loves this person, and he would leave you except he doesn’t want to lose me.” He gets it all out in the open, letting out a heavy breath. He looks up at his father.
And immediately wishes he hadn’t.
Tony’s face is screwed up in pain, disbelief in his eyes. “It’s Bucky, isn’t it? You saw him with Bucky?”
Peter winces. “He called him Buck.”
Tony looks down, and Peter sees tear drops fall to the table. Tony starts nodding, even though he has nothing to nod to. His head just won’t stop moving. “Thank you, Pete. For telling me.”
Peter feels his own tears form, and he lunges across the table, hugging his dad. He hides his face in Tony’s neck, not caring that he’s too old to sit in his dad’s lap. His dad is in pain, and while he isn’t the reason, he can’t help but feel responsible. “I’m s-sorry…”
Tony hugs Peter back, shaking his head. “I’m glad you told me, kiddo. I’d rather know.” He whispers. He kisses the side of Peter’s face.
Peter sniffles and holds him tighter. “What do we do?” He asks.
Tony closes his eyes, letting out a shaky breath. “I don’t know, if I’m being honest. I knew that when Bucky came back from Europe, there was a chance. Steve had said when we first got together all those years ago, that he was still in love with his ex. But then he married me, and we got you, and 20 years passed—I thought he was over him. But no, Barns shows up from Europe, and it’s like I meant nothing to him.”
Peter sobs at that. He wants to kill his Papa, and his papa’s lover. “I’m s-So sorry!” He sobs.
Tony sniffles and pulls Peter away. “Don’t be sorry. I’ll be okay. I- I need to go talk to your papa now, okay?”
Peter sniffles and pulls off of his dad’s lap, standing next to him and trying not to cry. He fails.
Tony stands and goes towards the bedroom.
Peter knows that when Steve leaves that room, he won’t ever be going back in.
And Peter cries, for a different reason now. At first, he was just so fucking angry at Steve, so in shock, so disgusted. But now… he realizes he won’t have his Papa around anymore. He’s leaving. He’s leaving Tony, but he’s also leaving Peter.
Peter feels like he’s betrayed his dad, by not wanting Steve to leave. But he doesn’t. He wants his Papa to stay, and to love his dad, and for everything to be okay again. But it won’t ever be like that again.
When Steve leaves the bedroom with an overnight bag in his hands, tears streaming down his face, Peter wishes he only felt anger and hate. But he doesn’t. He’s sad and he feels betrayed, he doesn’t want Steve to go, and 16 years worth of loving his Papa, leaves Peter crying. He throws himself at Steve, hugging him and sobbing into his chest. He’s shaking so bad, Steve can hardly keep him still.
Steve feels his own tears fall, as he hugs his son back. For the first time since Bucky got back, he thinks it wasn’t worth it. He’d rather shoot Bucky himself than be the reason Peter is crying this much. “I’m sorry, Peter. I’m so sorry.”
Peter sobs and pulls away, wiping furiously at his face. “You r-ruined everything.” Peter whimpers.
Steve sniffles and nods. “I know. I know, I’m sorry. I n-need to go, I’ll see you later, okay?”
Peter steps out of Steve’s way, glaring at the ground. He has so many emotions going through him…
Steve pauses at the door. “I love you, Peter.”
Peter starts shaking violently again, sobs wracking his small frame.
Steve winces and leaves, shutting the door softly behind him.
Peter curls into a ball on the floor, sobbing into his hands. After what could have been ten minutes or ten hours, he feels his dad’s arms around him, holding him, crying with him. “I’m s-sorry!”
Tony shakes his head, kissing Peter’s hair. “It’s okay baby. You can be sad too. He left you too, it’s okay to be sad. It’s okay.”
Peter clings to his dad, and they sob together, miss Steve together, hold each other. Peter doesn’t know how they’ll be okay again… but his dad is Tony Stark, and he’s Peter Stark-Rogers. They’ll be okay. They always are.
