Alyson will try to befriend him. He is a vampire and same year and house as her. So yay!
If you like, Kristen is also available. She will be sympathetic and while a wannabe vegan vampire may not be the best vampire coach, she will be willing to help where she can.
Nicole is in the same house and would be willing to help/chat.
Delphine will be very confused by him. She mistrusts males and will not understand why he doesn't speak.(I could see her yelling at him in different languages, trying to get him to make a sound).
