I wanna introduce her before I go to bed. This is Elaine of Corbenic. In this life she's Sam/Terps' older sister. And her name is Haylie. She recently moved here from Cambridge, MA. She's smart and pretty, tough and a bit manipulative, and she's in law school.
Her powers are being pretty. The only person she can't stack up to is Guinevere. And a golden chalice follows her around (she can't get rid of it) and it can heal people. Minor stuff only. She doesn't tell anyone about this grail, but she does tell people she's Elaine of Corbenic. She's very excited to meet people. And Lancelot.
