It's weird, I would have bet good money on this being a Buckleming episode, given how crowded it felt. But no, we're saving those chuckle-fucks for the penultimate episode, which just bodes... really super great and awesome.
Cons:
Like I said, this shit was crowded. In the span of one episode, we learn what Jack's final task is, learn what his weapon is and how he's going to use it to kill Chuck and Amara, see him implement said plan, and then fail at it, the episode ending with him on the verge of death with no outlet. It all happened lightning-fast.
And on the flip-side of that? I'm really feeling the pressure, considering there are only three episodes left, and I'm starting to get mighty nervous that our friend Castiel might not survive next week's outing. The trouble is... why has this whole last run of episodes been about Dean resenting Jack? Like, is there not enough else going on? The plot twist in this episode is really actually quite good, and it appeased one of my biggest worries about a way they might end the show in a really dumb fashion. But it's replaced by other concerns, one of which being that the Jack conflict feels manufactured, and has been given center stage for the end of the whole show. Jack is great, but why is Jack the main character after fifteen years?
