Can Sam and Dean stop the Darkness with a little help from the man upstairs? Maybe...not.

Supernatural finally revealed that yes, Chuck (Rob Benedict) is God, and he really needs the Winchester brothers to defeat his evil sister Amara, also known as the Darkness.

"She's relentless," he tells Sam (Jared Padalecki) and Dean (Jensen Ackles) in the exclusive clip above from this week's episode. "A force beyond human comprehension. It's the only reason I came off the sidelines."

Sam and Dean have their own reasons for wanting Amara gone, since she's currently torturing Luficer/Castiel/Misha Collins, but unfortunately other than a few encouraging words, Chuck is not going to be that much help.

"I have no frickin' idea!" he says when they ask if he knows where to find his big sis. "She's warded herself specifically against me."
