the song Alastair sings to Dean in On the Head of a Pin is the same one Metatron has playing for Cas in Stairway to Heaven
Yeah, this is why Metatron’s heaven instantly gave me the chills. Alastair was recalling something that had to do with Dean in hell with that song, so I initially figured that what Metatron gave Castiel wasn’t a mock-heaven, but it was hell.
But then I started thinking, hell is where he met Dean, so the song ties to the moment that they met. It was meant to remind us of Dean in place of the naked Deans they weren’t allowed to put it.
And let’s not forget that the first time Dean chose Castiel, he had to overcome his primal fear of Alastair.
and Metatron knew all of this because he’d read the Carver Edlund books. He knew that Cas had been the one who asked Dean to torture Alastair, and then felt bad for it. He knew that this was the moment when Cas seriously started choosing Dean over heaven
