there's something just sooooo like. bananas about Sam getting visions of burning bushes and his dead father and flashbacks of the Cage believing that it's because he's praying to God and God is telling him that he needs to go back to the Cage and there's soooo many implications in that alone and then. AND THEN. he goes back to Lucifer and Lucifer tells him that it was him all along. Lucifer reaching out from the Cage to bring Sam back in.
