Discrimination. Dave's poker-face finally cracks at that one, a little smirk slipping onto his face. Well, shit. The guy's got him there. Either he's bluffing like a champ, or he really is just a weirdo doing nothing wrong with every right to be here. And since he can't imagine any actual would try playing the innocent card while looking as conspicuous as is physically possible, that means...

"Holy shit. Wait. You're the Reaper guy, aren't you?" Dave's smirk widens slightly, almost a grin, and he leans a shoulder up against the wall beside them, every hint of tension gone. "From the comms. The one actually dedicated to the edgy bit, I mean, not the tryhard kid."

He assumes The Reaper is a kid, anyway. Definitely gives off that vibe.
