Description: Dean awakens five years in the future in an abandoned city and is attacked by humans infected with a demonic virus that makes them mindless, flesh-eating zombies. Zachariah soon appears and explains to Dean that the world he sees is the result of his refusal to help the angels fight Lucifer. // Dean moves to Kansas City and receives a phone call from Sam, who tells him about his meeting with Lucifer and asks Dean to hunt together with him; however, Dean refuses the request. Soon Zachariah brings Dean to 01 August 2014, i.e., five years in the future, to show him the effect of his refusal to permit Michael to occupy his vessel and Dean realizes that the world has been practically destroyed. Dean (2009) meets with Dean (2014) and he learns that he has lost his humanity and the world is crowded with people infected by the demonic deadly virus Croatoan. Furthermore, he sees that Lucifer is occupying Sam's vessel. Back to 2009, Dean changes his attitude, but not the way Zachariah is expecting.
