Heather! Patricia here, and we have NEVER played with each other before! Well, except for all those many games where we did. :P
This here is Cormac, whom Vicky will know from seeing him around the common room because he's hardly inconspicuous - and because he may have tried to hit on her at some point. He's actually a pretty cool guy who is trying to move away from his purist family's viewpoints, but since his flaws tend to overshadow his qualities it's very possible Vicky wouldn't have noticed it.
And then there's Hamish, who needs no introduction. He's a halfblood now, because his addition to the game was caused by Julie and I joking about him and Cass from ootp_newts being long-lost twins, but apart from that he's still the girl-shy kilt-wearing Scot you know.
