Scott lets his arm fall away from the guy when he grabs onto something a little sturdier to steady himself. He still keeps an eye on him, just in case, but he does seem to be a little better than he was a few minutes ago.

"I'll stay with you, til we're sure you're good." He assures him, smiling gently. "No, man, I believe you. We're literally in another universe where people with powers are seen as celebrities. Anything's possible." Though, he is curious how the guy could seem so fall-down drunk if he hadn't had a single drop of booze himself.
"You definitely can, but-- I dunno. People like it, for whatever reason." He shrugs. "I don't really get it, either. I've never even been drunk-- can't get drunk now, actually." But oh, how he had tried. Stiles was plastered that night, as bad if not worse than this guy is right now.
