I love Castiel. For one--he's often funny without meaning to be, like when he and Dean go to the whorehouse. He's gorgeous and deadpan awkward and his faith is so strong even though he has his doubts and concerns. It's been kind of sad for him because (SPOILERS!) he talked to someone who's been talking to God and he said that God knows what's going on, He's alive, but He just doesn't think it's His problem. It's really got Cas feeling very jaded and betrayed which makes me sad because he was so sure he could find God and He would fix this whole apocalypse mess. I'm going to get (or at least rent) all the seasons on DVD so that I can see the whole journey and where Castiel came in and all that.
It comes on Thursdays at 8 p.m. central on The CW & Monday thru Friday 9 & 10 a.m. central on TNT (after Charmed). It's an awesome show. =)
