It doesn't feel quite like an old routine for Bucky, who's only ever really had this sort of position with Steve, but it's not entirely foreign, either. He's happy to watch someone's back and have his watched in return, even if he doesn't think there's much around here that can honestly threaten him. He falls into step, watching their rear with his gun at the ready.

"Really? That's got to be rough work." Bucky can't imagine what some people must be like. He's had two years to process everything and it's still not enough and he's still missing enough that he knows he could easily get worse before he gets better. "It's good of you to take on something like that. You probably helped a lot of them."
