This episode was honestly such a gift? I'm very surprised by how much I liked it, honestly. Let's dive in!
Cons:
I won't go in to the plot that much, but one of the important elements here is that Cas steals the Colt from Dean. The Colt, since it returned this season, has been built up a lot, and so seeing Dagon just destroy it like it was nothing? Kind of a letdown on a major scale. I'm happy that Dagon was too bad ass to be taken down by a gun, but considering the fact that she got killed just a few moments later, it seems strange to have the Colt suddenly be gone. I wanted more out of it, after such buildup.
We get a semi-decent explanation of why Cas has been AWOL over the past few episodes, but it still feels a bit contrived. I understand the idea they're going for, but honestly? Cas could pick up the phone. He could send a text. He could make up some crap to keep the Winchesters off his back. His conflicting ideas about what to do, and how to get a win for him and his friends all make perfect sense. But would he really act that way in the face of these doubts?
Kelly has become a devout follower of the infant inside of her, which I think is a great concept and one I totally didn't see coming. However, I think this would work even better if we had some idea of who Kelly was as a person. If we had gotten to know her at all as a complex human being before the whole demon baby thing, all of the material with her would hit closer to home. As it is, I keep asking myself - what does POTUS think happened to his lover? The minute I remember Kelly was the President's girlfriend, it becomes a lot harder to take her seriously. Supernatural may have flown too close to the sun on that one.
