Changes

Michael first manifests when [[Sam]], Dean and Castiel have traveled back to 1978 to stop [[Anna Milton]] from killing [[John]] and [[Mary Winchester]] in order to prevent Sam’s birth, and thus his use as Lucifer’s vesseland preventing the Apocalypse from starting. Michael comes to John while Anna is attacking, and John consents when Michael says he can stop Anna from killing Mary. Michael incinerates Anna with a touch, and banishes [[Uriel]] back to [[Heaven]], and sends Mary to sleep. Alone with Dean, Michael explains that while Dean is his true vessel, he's not his only vessel as he can use others from Dean's bloodline. He also tells Dean his need of the [[Apocalypse]] and having a final battle. Michael tells him that his relationship with Lucifer mirrored Dean's relationship with Sam. He also tells Dean , and while he doesn't want to kill his view of the [[Apocalypse]]brother, and the need he will because he believes it to have a final battlebe justice. Michael believes that he is a good son who has to do what his father tells him to do because he believes it to be an absolute in any situation.

While Dean tries to counter himbecause of his experiences with his family, Michael insists that everything that he is doing isn't random. He says everything happened from John and Mary's birth, their union, and conceiving Sam and Dean is not random, but all part of a pre-ordained plan playing itself out perfectlyand he knew from the beginning that the story will end when he kills Lucifer. Michael says that "free will is an illusion," and that is why he will eventually receive his consent, though he won't leave Dean in a catatonic state when he's done using him as a vessel. He plans to erase Mary and John's memories of meeting Sam and Dean, under the pretense of giving Mary the life she wants. While Dean protests against it because of her death in 1983, Michael says that Dean knew that Mary's death was inevitable whether she knows the truth or not. He then heals Sam, and returns him to the brothers present. He says he'll see Dean soon before sending him back to the presentfuture. After erasing John and Mary's memories, he dispossesses John and returns to Heaven.
