He sticks around the bathroom long enough to pick up a couple of names to look into later, drugs or people he's not entirely sure on just yet, and slips out like he was never there. Just another patron enjoying themselves and not worthy of note, honest. Drugs are a continual problem in Gotham - and everywhere else, but Gotham is where he usually deals with it - and he's not going to ignore the leads he has. Though it might get a lower priority than other things, depending on just what he manages to dig into.

Back out in the club, and he avoids the main room - he doesn't qualify for the large VIP area, hanging chandelier-like over everyone else in a shining testament to decadence, so he explores further into the club's lower level. At first it seems like the red rooms are another VIP area, but it turns out that he just has to sign his name - so Alvin Draper, as he's been calling himself, signs the dotted line and strolls on in. He's trying to walk the line between new, slightly vulnerable face and not a "tourist" - and that's a little difficult when some of the areas back here are fairly open.

And open about what's happening.

It's not his first time in a sex club, although those times were decidedly infrequent when he was Robin (and he's certain that was delibrate on Bruce's part) and always in costume, so it was more a case of busting in and asking questions, or gathering evidence when no-one was there conducting... business. And even in Gotham, most of the clubs saved the BDSM for behind closed doors.

There are some closed doors in the red rooms, which just makes him a little more suspicious considering what's on show, but exhibitionism is a kink and a preference for privacy isn't a bad thing. Still, he makes a note to investigate as inconspicuously as possible, once he's done navigating the more public rooms and appearing interested for other reasons than he is.
