Iris watched between Tate and the Gryffindor as he excused her. And... the girl was argueing with some other Gryffindor. Laughing? Iris didn't hear any laughter.

As Tate called up some of the holster-less students, Iris made a couple of notes and doodles on her page, and waited to see how this demonstration was going to play out. All in all though, she just wanted that disruptive Gryffindor to LEAVE like she was asked. DADA wasn't Iris's best class, and this attention seeker was NOT going to ruin Iris's chance at getting a decent OWL in this class.
