HE'S HOT. I love him. I'm Tina and I have Adrian, Cho, Cormac, and Romilda.
Cormac remembers him, from the pitch I'd say. He runs a sports shop if Rich is ever interested these days and he's very friendly if Rich is looking for a friend (Mac needs friends!).
Adrian would probably also remember him from school and sells potions, so anytime you'd like any interactions :)
Romilda runs the local sex shop and would remember him from school, though she was quite younger.
Cho also has some baggage from the war and would definitely remember him from her sixth year with Cedric.
