Damnit! I LOVED Ava!!!! The actress, Katherine Isabelle, was just awesome. I loved her, loved her, loved her and her first episode actually made me like Sam (generally I just tolerate him, it's an understatement to say that Padalecki does nothing for me) and they made her not even a demon, but a human who became corrupted by power to become evil. DAMNIT!!!
So pissed. Oh yeah, Sam "died." Eh, who cares. They killed my Ava. Fuckers
