I'm Sami, bring you Dorcas Maeve Meadowes. She's seventeen, a future healer, and, since we know next to nothing about her in canon, in need of friends/enemies/etc! The bulk of her application is up at her journal now, but the long and short of it's that Cas is a smart, hard-working, disorganized and mildly neurotic Ravenclaw. She'll chatter your ear off, and, heaven forbid you say a thing in favor of blood purity, might try to hex you into kingdom come. Cas is certainly curious about the visitors, and frankly, a bit unnerved.
I can be reached at feetxofxmud and sodisarmingdarling@gmail.com :)
