During this week’s “previously on Supernatural” montage, we heard Zachariah say, “How many times have you two died anyway?”, so it shouldn’t have shocked you to see Sam and Dean gunned down by two vengeful hunters in the show’s opening moments. They apparently knew how the apocalypse would be started if Sam accepted Lucifer, so they killed him to prevent it. Then they shot Dean to death because they feared his wrath. Also predictable was the fact that Dean wanted to be murdered after seeing Sam die.
But the predictably ended to the sound of “Knockin’ on Heaven’s Door”, as Dean woke up in the Impala and was greeted by an adolescent Sam. Just as the two was having a happy moment, shooting off fireworks in a field, the vision disappeared. Dean then heard Castiel break in over the car radio in order to tell him that this was not a dream and he was actually in Heaven. In the Supernatural universe, despite the fact that the moon looks really weird, Heaven looks a lot like Kansas. Dean follows Castiel’s advice to drive down the road, but he finds himself in a strange house, watching a grown-up Sam eat Thanksgiving dinner with an unknown family. Sam then tells Dean that he woke up there, at the home of a classmate who once invited him over for the holidays. Therefore, Heaven, as Dean explains it, is “a chance to replay your greatest hits”.
