Okay so. Vee absolutely loves him. A lot. Not just because he's hot (omg MGG *_*) but also because the girl is turned on by ambition, and ambition to being an Auror is pretty hot. Also, he's smart. SO ... yeah.
Mary probably doesn't know him that well, if at all, what with the age and house difference, but she'd be nice.
Aaaaand Will is in the same house, though a year behind. But he'd probably know Edgar and, y'know, he's got that Older Brother thing going, too, so. Yeah. He'd be friendly!
