[Despite the seriousness of the situation, Bucky can't help but smile in response to Sam's words, however slight it might be. He trusts the man more than he trusts himself. Knows that, no matter what happens, Sam will make the right choices when the time comes. No matter how difficult they might be. Yet here he is regardless, trying to ease Bucky's worries. Because that's just the kind of person Sam is. The kind of hero.]

Only think I need you to do is make sure I don't hurt anyone. If that means you tell me to go sit in a corner all week, fine. That means you need to knock me out, do it. But whatever you ask me to do, I ain't holding any of this against you.

[Because he needs Sam to understand that. To believe it. Even if he does need to walk off and take some time to himself after, it won't have anything to do with Sam himself, and everything to do with the people who did this to him in the first place. Everything that Sam's doing now, that he's willing to take part in, is to help. Not to hurt.

Which is why, a moment later, Bucky reaches up to pull his dogtags out. Why he doesn't hesitate to take them off and hand them over to Sam instead. One of the few pieces of his past that he still clings to, being held on to by the only person in his future that he needs.]

I'll be back for those.

[However long it takes.]
