After being out in the field for a month, Sam accidentally calls Bucky "babe" during a debrief meeting in front of Rhodes, Fury, and several others. Naturally, Bucky doesn't let it go. Bucky starts calling Sam every stupid pet name he can think of whenever someone else is around. Sam tries to ignore it, but now people keep asking him if he and Bucky are a thing, and they're not, no matter what Belova tells you. Except... when one of Bucky's pet names strikes a chord, Sam starts to think that maybe he does want them to be a thing after all.
