[Teddy has threatened to maim people for Billy, stood at his side even when the Avengers thought he might be a threat -- because he knew Billy. He knew Billy would never want to intentionally hurt anyone -- even when he did want to, he hated himself for it after.

Even when he left, it wasn't that he hadn't trusted Billy exactly. He knew Billy wouldn't intentionally control him or hurt him. He wouldn't have intentionally wished up a boyfriend, let alone a boyfriend who'd have to watch his mother die with his own eyes.

Right now though? His trust is shaken and it hurts. Billy had always been enough for him. He could have lost everything else in the world, but he'd still feel like the luckiest guy alive if he had Billy with him. It's why he stuck with him, tried so hard to be what he needed through every depressive episode, could shoulder his own losses because of it.]

What if I don't want you to come back with me? [It's not true. He knows it even as he says it. He asked Billy to marry him -- and maybe partly as a desperate act to get him off the windowsill, to react to something, but mostly because he'd wanted to spend the rest of his life with him.

He just doesn't see how that can happen now. Billy's moved on and he hasn't even been given a chance to yet.]

Well, you did, Billy, whether you meant to or not. [He manages to squeeze Billy's hand back where he's still gripping it, though he still can't bring himself to look at him.

And it isn't even that what Billy is saying doesn't make sense. He'd rather know now than be lied to or have false hope, but it doesn't make it any easier to process. It feels like he really did end up in his worst nightmare.]

Right. I'm sorry I can't forgive you right now, Billy... or know when I'll be able to.

[If ever, really.]
