Non-powered AU with flashback scene
I can't remember what pairing this story is, just a scene where the characters are in a nightclub and there's a song with gunfire that triggers one of them. They end up outside, trying to come down from the flashback. Pretty sure it's a non-powered modern AU and the character in question is a veteran. I'm also pretty sure I've seen fanart for this story, so I don't know if it was part of a Bang or just had art done for it.
