[Steve sighs, keeping one eye on Bucky as they walk. He wants to say there's nothing to be sorry for, but he's not entirely sure that would help right now. It might make things worse, actually. Might make Bucky think he's making another mistake for apologizing.]

It's alright. Apology accepted. [Steve smiles, trying to keep things light, but it's a little tight, a little strained. They'll figure this out, they will. It just... might take a while.]

I know... there's... going to be a lot that's hard, for a while. For both of us. But I want this to work, Bucky. And I want you to know that I'm not going to give up when something goes wrong.
