So... no clue who Mal is? Boot?
Here you go:
Hannah Abbott: Hufflepuff. Harry's year. Cheerful but not stupid. Is hard pressed to take no for an answer.
Malcolm Baddock: Slytherin. Was three years behind Harry and the gang. Most often, I depict him eating on-screen. He's not very bright, but sort of asshole-ish in an offhand way.
Terry Boot: Ravenclaw. Harry's year. I often pair him up with Hannah. He's not very fond of cats.
Millicent Bulstrode: Slytherin. Harry's year. Gruff and square and puts up with a lot more than you'd think she would.
Neville Longbottom: Gryffindor. Harry's year. You know who he is, right?
Random whosits:
Floo: the fireplace... a method of traveling.
Um... did I use any other magic terms? D'oh. I think my brain is broken.
