As far as Juno is aware, the man in the brown jacket's appearance means that he hasn't undergone any transformations yet. A new arrival, most likely. The thing is figuring out where the guy came from--and, more importantly, when. Juno had been in this place for much longer than he could have ever anticipated, and past encounters have taught him that time is a nebulous concept when it comes to the Fog.

"That's not what I meant," he says, slightly frustrated. He should've known better than to ask the big guy vague questions like that. "You know what? Never mind. How long have you been here?"

Anticipation creeps into Juno's voice. It's hard to get a good read on this guy, and for a moment, Juno considers the possibility that this man doesn't recognize him. But he must--he mentioned Buddy, after all, so that must mean something.
