I think fans' hearts broke a little last week when we found out that Cas has been teaming up with Crowley (and let's not forget him faking the demon's death). According to the episode's writer/director, Ben Edlund, that partnership, and not Eve as we thought, has been behind the horrible state of affairs in the world this season:
"The real driving catalyst, the reason why more bad has happened to good people on 'Supernatural' this year than any other year, does not come directly through the Mother of All monsters. She's badass, and she does bad things, but it's this partnership between the angel and the demon that has driven most of our conflicts. It's all because of Crowley and Castiel."
As if that's not bad enough, this betrayal will hit Dean particularly hard, as he has come to view Cas as part of the family. And nothing hurts Dean more than familial betrayal:
"He won't like it. Familial betrayal is his kryptonite, so to speak. It's his thing. It's the thing he hates worse than any other thing, and he has brought Cas into the family, so the math there has a clear outcome. It's going to hurt him deeply even to discover what we understand to be the case right now, which is that Cas is capable of working with a demon. Even that is going to be so painful. It's going to be a hard week for that good-looking bastard."
Like Dean hasn't been hurt enough. So why make Cas work with a demon and crush Dean? According to Edlund, the decision to write this did not come easily:
"I had my hesitations because I like the fish-out-of-water, dumb jokes, and I like Cas. I like the thing on camera that Misha created that complemented this new strain of creature, this angel coming into our world and gave a body and character to it. That's a really great thing. But one of the rules of 'Supernatural' is loss, and losing things. You have to love something before you can feel its loss."
Anyone else afraid of Edlund using the word "loss" in relation to Cas? And how do you think this "so Cas is evil now?" thing will play out? Head to the comments to share your thoughts!
