Castiel (Misha Collins) is back on his feet once more, and as "Our Little World" proved, his spoiling for a fight. Now that the Darkness' claim to fame has been revealed (she has a very, very well known brother), Collins has revealed that Cas' attempt to take down the deity's kin will not go according to plan.

"Cas's number one objective at this point is to extinguish the Darkness in some way. For him, that ends up going very, very, very badly. As badly as-- I mean really badly," Collins informed Buddy TV. "In an effort to combat the Darkness, in a sense, Cas makes another deal with the Devil that becomes another one of those things that everyone probably knows is a bad idea, but he does it."
