I love, love love love that this episode (this season? From now on? Yes?Yes?) is so full of the unknown, again, I missed that so much from earlier seasons.
The boys are again dealing with unknown powers - so much bigger than they are, powers that might be more horrible than anything they'd faced, might have grace, might have mercy, powers that don't necessarily fit into "good" and "evil" because they probably have their own agendas, their own way of understanding the world....
I love that Sam is hearing voices/seeing visions again - are they from outside of him? Memories? Are they for or against him? The voice calling him not to touch burning oil to his skin - was it compassionate, protecting him? Was it trying to get him to let himself die? And in the same episode, we get Billy (whom I LOVE), with her own complex agendas and perceptions, and knowledge, who knows from where. Threatening to make Sam suffer, also giving him the clue he needed to save himself and all those other people....
I love that religious stuff is back to the show, and that is not a thing I expected to love.... Sam talking with God - like praying as a kid, like Dean praying for Sam two seasons ago - only Dean was making a call and offering a deal, Sam is truly talking with an unknown force, more questions ........
And then the church sending help - and it actually being knowledgeable and with the power to be helpful - but not being very helpful - being very known - with its own agenda and knowledge
and all the angel figurines.... Ilove that something with so much symbolism on the show was so present - this religious or not symbol, that may be 'watching the Winchesters in their sleep' - possibly comforting, possibly terrifying - possibly broken now and not relevant, possibly something else, large, from before time....
ok, i squicked myself a bit
