The mutual clinging is actually pretty comforting, in Steve's book; if they're both desperate, at least it's somehow a reassurance that B feels the same way. (As if Steve didn't know - he did - and B's words make that very, very clear, a moment later.)

"Please do," he says, even though it sounds too much like begging. He doesn't want to go back "home" alone. That place isn't home anymore, that Bucky isn't his anymore, if he ever was. And it's - fine, it's what Steve had wanted, and he might feel sad from time to time, but he's not sorry he walked away from that place without ever planning to return.

Of course, that thought makes him laugh a little, hoarsely. "Better do it fast, because I'm gonna have to stay in hiding and pretend I'm dead, if I end up back where I came from."

But joking aside, "You, too. You know I'll come after you, too. Anywhere, until I find you."
