Supernatural

This Thursday marks an important episode in the Supernatural lore.

Titled "The End," the installment finds Dean waking up five years in the future. He's in an abandoned city and is attacked by humans-turned-zombies that have been infected with a demonic virus.

Dean soon learns that this world exists because, in the present day, he turned down the chance to help the angels fight Lucifer. Oops! Watch a clip from "The End" below:
