Lords of Kobol, hear my prayer...

'That's also very interesting, Castiel has more humanity than Sam does right now, he feels while Sam does not. Fascinating.'
It is a nice contrast. It does make me wonder why exactly not having a soul makes you not feel. As far as we know Cas doesn't have a soul (why would he need one) and even if an angel's grace can stand in for a human soul, future!Cas lost his grace and he still felt. Although maybe he's feeling things through Jimmy's soul. Sadly I don't think the writers really thought through the implications of No Soul = No Feelings beyond it makes Sam the bad ass hunter Sera always wanted. I like how in the preview clip they mentioned that Sam doesn't sleep; so he's basically an human!angel now. Who knows maybe Lucifer and Sam have their own profound bond in that Lucifer burned out Sam's soul and replaced with his own grace.

'I'm personally speculating that this could have our characters understand where they belong, which path is the right path for them and discovering something about themselves. It might be a long-shot knowing this show, but I got to believe that this might be progression of character developments. Finding out things they wanted weren't things that made them happy. It has to mean something, right?'
I hope so too. It makes so much sense that the writers would tie all those characters getting what they wanted but not really wanting it together. Please let them do something with that.

'It's just heartbreaking watching Castiel in that scene as Dean is yelling and cursing at him when. His face is almost crestfallen and you can tell he wants to tell Dean what he's been doing, but he cannot for his protection. I do hope there is a scene at some point acknowledging this.'
I want that too. Is one scene really too much to ask.

'It was done excellently.'
It was. I love how there was no background music for that scene because it adds to the starkness of it.

'This. It's nice seeing their dynamic played out on the screen, they have such amazing chemistry it's insane.'
So true.
