Three weeks after Apocalypse World Michael possessed Dean, the archangel is confronting individuals of every different species, questioning their wants and dismissing them as hopeless, until he encounters a vampire who expresses his desire to eat. Praising his desire as pure, Michael decides to raise monsters above mankind and begins experimenting with archangel grace and monsters, making them immune to their former weaknesses. Sam, Bobby from Apocalypse World and Mary track Michael down, and Michael seemingly leaves Dean's body after becoming irritated with Dean's resistance. Meanwhile, Jack becomes sick due to the loss of his powers, and dies later, his soul ascending to Heaven. But the Shadow being from the Empty, believing Jack's soul belongs to it and irritated with Castiel for escaping it, attacks Heaven and makes a deal with Castiel to take the angel in place of Jack, but only when Castiel lets himself be happy again.
