This here is James Potter! 6th year Gryff. He'll probably be cool with her.
Emmeline Vance, 6th year Ravenclaw. Probably the most likely to get along with her. She's a fierce studier herself and a bit of a perfectionist.
lastly, Jin Chang. 7th year Hufflepuff. He's a Seeker like her so maybe they have a friendly rivalry over it? He's a nice guy so it'll never be anything bad.
