Well I loved it. It was meaty, intense, high stakes, and subverted a bunch of expectations IMO.
I believe the future-cast was real (ish). Real enough in that Chuck clearly knew the plan was to trap him and that would result in Cas going insane and being at the bottom of the ocean in a Malek box, the monsters run amok, Sam and Dean get overwhelmed. Not real in that I think individual choice STILL matters -- no matter what Chuck says. So I think Chuck showed the most probable outcome. And therefore was likely telling the truth about trapping God unbalances nature (or something to that effect) and the monsters win. Therefore, Sam (IMO) made the right choice.
LOVED Dean/Cas hashing it out. Cas just has no f*cks to give anymore. He laid it all out, baldly, everytime he got snark from Dean. And I like that Dean said "of course I forgive you". Because I think Dean DID forgive him. The anger is just his coping mechanism. And Dean is so very self-aware. He knows his response to pain is anger. And he also knows the danger of just letting that lay there without resolution. I'm glad he took the time for that prayer and then was heading back to the entrance. I'm also glad Cas just acknowledged he heard him and that's all Cas needed. I love these two.
The boys snark-off with Chuck. LOVED how neither Sam nor Dean are going to back down in front of Chuck. Chuck knows it. Fist pump from me when Sam flat out said "Dean raised me!".
I'm glad the wound is gone.
I'm bummed Eileen had to go but it makes perfect sense. I'm glad Sam laid one on her before she left and that she left knowing how he felt.
I swear, Chuck was into Dean getting up in his face. I don't know if that was how Rob played it or planned but I get why Dean gets the full frontal sex scenes in the book with Chuck. I liked that Dean threw a punch and so did Chuck -- excellent snark-off.
Subverted Expectation: Get the 'blossom' to trap God McGuffin was previously a season-long kind of arc. This was a one and done. I think it means the real End is going to be much more sophisticated.
Jody Mills/Post-Apocalyptic Action Hero; You go girl. She had some moves.
Ending: Jack! I'm looking forward to his return. I don't think it'll be next episode. I think this is like when Cas was in the empty. I think this is going to play out as background for until the episode after next (or even one more after that). I wonder if Death was waiting to see if TFW went the Trap route and once they didn't, she felt she had to engage.
Really excited for the rest of the season!
