OK well let's start with my Gryffindor! Bronwyn would have most likely clashed with him in the past, but right now she's depressed as you know, so she probably just ignores it. I'm sure that's probably worrying to her friends! But I think they should be sort of friends, like they don't necessarily get along, but they'd be there for the other one?
Josiane thinks he is a complete ass if albeit a cute one. She thinks he's too cocky for his own good and isn't that good of a quidditch player. Will be interesting to see how they get along on the new quidditch team!
Wayne would have ignored him, like thought he was an ass, but left him alone.
Thomasina thinks he's an unbearable ass, she has a hard time tolerating him for longer than 30 minutes. But if she's not with Kit she probably wouldn't have said anything to him.
Cho, oh Cho thinks that he should have come to the safe house last year even if that meant more children for her to take care of. Though she still thinks he's ass ;)
