Fox could tell as soon as Charlie walked in that he was pissed, and it was all the angel could do to keep from grinning. Sure he was in cuffs, drunk as hell and the school was being inspected, but he'd had a hell of a fun night. Hell, even if he was grounded, he didn't care. Totally worth it. The school had survived and passed inspections before, so there was no reason to assume something different would happen this time.
He rubbed his wrists when the cuffs were taken off and followed everyone silently to the van. Silently, he was thinking 'Shit! What a night!', but he knew that Charlie of all people wouldn't appreciate the humor at this point. Seeing the way the vampire cut off his favorite demon from speaking, Fox was wise - for the moment - and kept his own mouth shut.
