So many thoughts running through my head after watching the recent episode.
First of all, the first few minutes greatly shocked me. So the reason Cas hasn't been responding for the past six episodes is because Naomi was training Cas to kill Dean over and over again. I kept yelling "Why!". Naomi is so manipulative and sadistic. I really do hate what she made Cas do, but I love this character for being a very competent villain. And apparently she and Crowley had a history, looking forward at seeing that explored a little more. I was always intrigued with her character and I actually still can't bring myself to hate her. I guess maybe because I loved Amanda Tapping's acting and I keep being reminded of her being Samantha Carter back on Stargate SG-1. I have the same problem with King Uther from Merlin since his actor Anthony Head played Giles in "Buffy the Vampire Slayer". (It's always difficult for me to despise their more-recent villainous characters when constantly being reminded of their good-guy characters from growing up).
It was painful to see Cas beating on Dean with Dean begging him to stop. It was touching to see Dean trying to break through to Cas, which prevented Cas from killing him. Glad to see that Cas has broken off from Naomi's influence. I wonder what he will do with the tablet now. What I'm hoping is that maybe the tablet shows a way to bring back angels that died. If that's the case he could revive the angels he killed such as Samandriel and Balthazar. Maybe Gabriel can even be revived. I wonder if I maybe too hopeful. In any case, I hope the tablet could give Cas insight on how to redeem himself and fix the stuff he did to heaven.
As for Sam and his trials, I hope he'll turn out okay. Though Cas mentioned that Sam's become damaged in ways even he can't heal, I don't think he is necessarily dying. With Cas mentioned Sam effected at a subatomic level and electromagnetic fields being involved, Sam could just be changing into something still unknown.
I am sad to see Meg die, but at least she died in a heroic sacrifice/redemption kind of way. Even when Crowley mentioned how the Winchesters plan to close the gates of Hell and kill all the demons, Meg didn't really falter and still fought Crowley off and gave the boys the time they needed. Though I am a Destiel shipper, I did find the Megstiel moments kind of cute. I guess the writers may have wanted to give the Megstiel shippers some nice moments before killing her off. Who knows, maybe the demon tablet has some way of reviving demons.
The preview for the newest episode has my brother and I excited. We had a discussion awhile back about what we wanted to happen or brought up in Supernatural. He mentioned he wanted Supernatural to bring up something about training the next generation of hunters with Dean and Sam to be the mentors. And now the next episode has something to a hunter training school. Can't wait to see how it turns out.
