Supernatural's Misha Collins previews a 'damn desperate' Castiel

"Cas is still looking for a solution but he's losing steam a little bit," says Misha Collins. "Cas still feels like there has to be another way and yet, as the chips are falling, it seems like there are fewer and fewer options." As Collins describes the trenchcoat-wearing angel, "he's damn desperate right now."

With only four episodes left, there's always the question of how Castiel's story will end. "For years, fans would ask, 'How do you see Cas ending on the show?' And I've always said in some heroic sacrifice," says Collins. "First of all, the phrase has heroic baked into it, which I like. But also I think that that's just integral to his character. He's always been willing to sacrifice himself for the greater good, and ultimately if he can sacrifice himself for the greater good and for his little cabal of humans who have become his family, I think that Cas will have served his purpose as far as he's concerned."

Whether Castiel gets his "heroic sacrifice" in the show's final season is yet to be known, but Collins teases that "sacrifice is sort of part of the equation for Cas." It's unclear what exactly that means or how it will play out — let's not forget he's already sort of sacrificed himself to the Empty — but all Cas knows at this point is that he doesn't want his son to die. As Collins puts it, hearing Jack's fate was "the worst thing imaginable" for Castiel.

Supernatural airs Thursdays at 8 p.m. ET on The CW.
