Bee here, with my last one, Megan Jones.

She's a muggleborn, bubbly, chatty and very friendly. She's been a bit out of the wizarding worlld lately as she's studding at a muggle university in London. She's very nice, but a bit stuck up, due to her upbringing; she can also have a really big temper, and hold grudges quite a bit, but she'd have to be pushed to a point.

Other than that, Megan's been working with an Interior Design firm in Diagon Alley a few days a week, which she'll scale down over the year. She'll probably talk to everyone in her year at Hogwarts, though she is very leery of purebloods at the moment, after everything that's been going on.
