After spending four months thinking that Castiel was going to be the new big bad for the year, as a ruthless god-like figure, mostly all viewers would have been shocked when that story was put to bed by the premiere’s end. Instead, we learnt that Purgatory wasn’t just a hang out for the souls of evil, but rather some of evil itself. More specifically, the Leviathan. Touted by Death as the first monsters ever created, the exceptionally powerful Leviathan took control of Castiel at the end of last week and that is where we picked up this week in the third part of an ongoing arc."
