Missouri! I love her! I just watched "Home" a week ago too. Hehe. I love whenever she picks on Dean, like saying he was a "goofy looking kid" [which Sam highly amused by that hehe] and makes him clean up the house, and scold him to not curse at her.
She was awesome. I'm sure Dean probably loved it hahahaha. I would love to see her come back. She even kept it real with John.
