Two Homeless Guys

Canon AU, Potential spoilers for the Winter Soldier. Four years ago Steve Rogers left SHIELD over some 'disagreements'. Three years ago he ended up homeless on the streets of New York. Today he's tired, he's hassled, and that even before he bumps into a powerless (if sarcastic) Loki. Just what he needed right now, except Steve's honor can't quite leave the injured villain alone.
