[He has a point there... it's clear that he's not the only one that's fallen for the champagne, especially since various guests are taking them without much of a thought. Still, even while acknowledging all that, Scott can't stop himself from frowning because he's a X-Man. Doesn't that mean he's supposed to be more careful and everything?

Granted, he's already done a lot of things in this place that isn't really 'respectable leader' behavior. He's just thinking more about it for once, that reckless mumbling in the back of his head a little quieter right now. Probably won't last long. It's been so hard to control himself in this place, something that he blames on the 'suit' crap and not because he's still so inexperienced and young--]

You didn't take a sip. [Scott points out, squinting at him from behind his glasses.] So, you're not going to, right? Actually, shouldn't we stop these people from drinking the champagne?

[Time to just run around the place slapping champagne out of everyone's hands!!]
