Steve definitely feels a bit of relief; maybe he hadn't expected Lark to protest, but it's still nice to get that acceptance.

He nods, though, because, "Yeah. I'm - I'm gonna stay with him. After this." For as long as the Admiral - the universe - will let him.

There's a pause. "B's Steve. In his universe. He - left him. And I even understand why he did it." He is, after all, going to leave his own Bucky. And isn't that complicated and complex, and dredges up so many feelings, from guilt to bone-deep sorrow to relief. "But I can't. I won't. I - don't want to."

He takes a breath, and glances up at Lark. This might be the only person on the Barge that will really, truly understand what he's going to say next. He might have said it to Annie first. But Lark... Lark was his best man. "My husband is gone. If it was even the same man that I'm going back to... he won't remember. He can't remember. This isn't like what HYDRA did. It never happened for him. I - can't. I can't go back to him. I can't stay there."

Please, please understand. It feels like tearing his chest open in a way that even talking to B and Annie doesn't.
