Yeah. It's like Survivor on crack. Cas and I were the only living things in the whole place. I was there for a year, Cas must've been there longer because when I got out, he wouldn't come with me. This angel bitch, Naomi, grabbed him out of there so she could brainwash him and use him to hunt down the angel tablet.
Cas is human now, so you know. Metatron -- the old scribe of God -- stole his grace to fuel a spell to throw all the angels out of Heaven.
