As the other man stepped forward and took the amulet in his fingers to look it over, Troy raised an eyebrow. A frown was less what he'd expected to see than a look of confusion.
Once he let go of the amulet, Troy took a step back reflexively. Dude was a little too up in his grill for Troy's taste, really. "Well...I don't know. I never met a demon personally but I know they're around a lot. People hunt 'em and stuff, or whatever, there's classes on exorcisms so maybe?"
Troy paused, then, before continuing. "They have a whole shitload of these things at the complex, man. Everybody gets one when they move in. It's just kinda what we do?" he asked more than stated if only because the man's tone and the look on his face made Troy uncertain of himself.
