Jack starts when the hot blond makes eye contact with him and looks over his shoulder. Who's he talking to?

"Me?"

He does recognize him as someone not from the simulation--he's dressed wrong, like Jack, who never managed to find an outfit that wasn't the suit he'd arrived in and now wishes for something more casual.

He also might recognize the nickname as someone he bumped into his first day. "Bucky, right?" Jack shakes his head, smile turning dark and wry. "Sorry, we just share a face." Weird though it is.
