You're Captain America, [Bucky says, immediately - he can't help it. It's practically automatic. After two years, he still feels like a sham, even though he's been Cap about as long, now, as Steve had been.

But this is Steve, and Bucky's gut clenches uncomfortably when he speaks again.] I understand you think that, [he says, quiet and low. Almost threatening, but it's not, really. It's just... sure. He's sure that is what Steve thinks. But it's still bullshit.]

You don't have to be my friend. But I can fucking be yours. It's a two-way street, Rogers.

[Well - looks like they're turning it into a one-way street, but like hell is Bucky walking away again. Like hell is he not going to be here for Steve Rogers. It's what he fucking does.]

You want me to pretend we've got nothing to do with each other, [he surmises, based on Steve's actions now, and what Steve - the other Steve, not his Steve, this is his Steve - has told him about the other Bucky Barnes.]
