I know, this is really becoming an issue and I'm not even sorry, but this is Cate again and this is my third character.
His name is Benjy Fenwick. You know him canonly for being a really bad ass Order member who ... sort of ends up blown to smithereens. Right now though! Right now he's all in one piece so, yes. He's a sixth year Ravenclaw, a chaser on the House team, and a prefect. He comes from a family of four, two older brothers and one younger sister. He's a muggleborn and everrrrrybody knows it because Benji is super proud of this. Suck it purists. He tends to be rather blunt which certainly detracts from people perceiving him as nice even though he is nice! He's just unfailingly honest and prefers being logical over emotional so- that's a quirk of his.
