Hello and welcome! I'm excited for more Slytherins! I have Tracey Davis, who was in Daphne's year/house/dorm/etc. I don't know if you want to work out any possible school time Castle friendship or not, but I thought it might be fun. Especially since she's totally an unpleasant elitist bitch and would love to be nasty to Greengrass now for having anything to do with Weasleys. Totally your call though!
Also, I got a notification talking about Daphne as a possible informant for Michael Corner? If you're still up for that, then that would be great! If not, then that's cool too. I'm pretty easy going.
I also have Hannah Abbott and Alicia Spinnet. Hannah's just sort of...around. She works at the Three Broomsticks. Alicia is crazy and prone to bouts of violence. She'll be playing on the new team with Ginny. So yeah, that's pretty much it. Feel free to get in touch with me if you have any questions/concerns/comments! :D
