Ty hasn't been burned by the anonymity charm just yet, so when he turns and sees another griffin looking back at him he assumes without hesitation that it's Quinn. Even if the effects of the spell make it somehow...difficult to tell. The shape and colors and contours of the mask, even the pretty eyes and the lips that he should know, seem unfamiliar to him. It's sort of a head-trip. Still, he grins. "Hey! It's sort of...crowded for Potions, don't you think? I mean. Unless you want some really interesting pictures from the photobooth."
