There's no big open skylights immediately above them, just lofted ceilings and fluorescent lights, but it's not hard to imagine that unearthly thick mist lolling about just outside the walls of the building. And that train of thought just leads to so many questions he doesn't have answers to- Like how in the hell it wasn't in there with them yet? It's not like this place was vacuum-sealed. And, like the other man had asked, what were they waiting for?]

He's too damn sick of it to bother being rebellious.]
