Sally will still try and be friendly, regardless of bad things from school.
Nora will be Nora.
Orsino doesn't really know him tbh.
Oliver will probably give him some shit, but he's also with Daphne so :please
Uh... He might know Melissa's family? Purebloods with a lot of money who basically peaced out of that inner circle so she didn't have to deal. His parents probably had a bad opinion. Maybe. Anyway.
Neville doesn't really like you still :p though he feels bad about Draco's mum. That sucks.
