This place is weird, but it has its own rules. There's plenty of them and they don't all make sense, but he's quick enough at picking them up enough to keep his head down as he looks around, gets a feel for the place. It helps, having Natasha as sort of a resource, although he still hasn't chased down the memory of why he knows her as something other than a target, or an obstacle. It'll come back to him eventually. They all do.

He's finished his assigned job for the day, which consists mostly of shouting and reminds him a whole lot of the good old days in Alsace, training up his squad. His boys, Sgt. Barnes' boys. This job isn't like that on the surface, and outwardly he's still unfeeling and stolid as he goes about his day, but underneath he's even closer to feeling like Bucky than usual.

Which is when Steve knocks, not five minutes after he's gotten back to his room. After a startled moment, Bucky gets up, a half-grin already forming as he stands near the door, not reaching out to open it, not yet. "Yeah? What's the password?" he calls through the door, as Brooklyn as he used to be in the really old days.
