Brigitta shall be giving you a suspicious look now Xander, she does not detect alcohol entering her system and so it might not have been given to her, which invites the question of why it hasn't been given to her.. Which is a mental process too far so she'll just be making vague beckoning motions at Xander and muttering "lo-los, gimme a sec... Lost the bottles?"

But she is quickly distracted, since her concentration at normal times is awful, and her concentration while drunk is even worse "Yeah! 'S awesome, best party ever, lotsa booze."
