Oh you will just LOVE it, it's so cool, but I won't spoiler. Just that the title is a VERY very good hint. And I'm kinda mad at him right now... because it's all right and reason with the trust issues and such (notwithstanding that Dean kinda trusted Castiel over Sam as well...) And I can see why there would be a rift between them. But going there and letting Sam wallow in all the weight of the world on his shoulders without telling so much as a lick of 'oh btw Sammy you suck for setting Lucifer free, but you couldn't have really, if I hadn't broken the first seal you know...' THAT irks me. Makes Dean a self-righteous little wuss right now... and Sam reached out to him again and again. I think he's in denial... someone should club him over the head. HA.
