It doesn't escape Derek that Stiles has picked up the pace and the reason for that isn't lost on him, either. So Derek matches it. If anyone happens to pass them by and believes them to be on their way somewhere important as opposed to just strolling along to kill time before curfew, they're less likely to be approached. Stiles is one of the smart ones, he remembers. Lydia and Stiles: book smart and street smart, respectively. He makes a mental note of that so that he doesn't let it fall to the wayside. Trust Stiles, he's good at this.

"Mostly the stuff with me in it, because I can't verify with my own glitch if I'm not in it," he points out. "Or if I wasn't at least present for it." Derek opens his mouth to answer his question about the roommate but Stiles cuts him off, changing his mind. Fair enough, he thought. It was probably better if he didn't go spouting it off, anyway. He got the feeling Buffy wouldn't like it and he really does not want to be on her bad side, just in case he's right about the fact that he's pretty sure she's a hunter and he's a werewolf and those two things do not go well together.

Derek stops when Stiles does, looking around. There's not a whole lot of activity out here, he's noticed. Everything about this place looks so weird to Derek. He remembers Brooklyn and he remembers Beacon Hills, but neither of them looked like this. There's signs everywhere, neon lights to accentuate some of them, and most of them are specifically reminders to citizens. "In here?" he asks, lifting his eyebrows in question, just to clarify that they're on the same page as to the reason why Stiles has stopped in this particular spot. He looks over his shoulder one more time to verify that they're not being followed, but he doesn't see anyone. Seems safe to proceed. He hopes he's right.
