Mary was there, though her hair was charmed blonde and she wore a mask that covered most of her face. She favored her left arm a lot - she should still be wearing a sling, but decided it would be too obvious to wear the thing in public.
She brought James a signed dueling glove from the top seeded dueler in the circuit (...who... I don't have a name for. Make one up.) and a book called Teaching Quidditch to Children: How to make a Superstar.
She wouldn't have stayed long, but had a few drinks and then headed back to Hogwarts.
