Supernatural 2011 Spoilers: Series Creator Eric Kripke Warns That There Will Be Surprise That No One Will See Coming

It sounds like Supernatural is building to something… well, Supernatural.

The show’s creator, Eric Kripke says that the show is “building to a left hook that I don’t think [fans will] see coming. We will bring all of this mythology to a head. We bring purgatory to a head. We bring the war in Heaven to a head. We bring the mother of all monsters — the wall in Sam’s head — to a head. All of it does come together, but I think in a way that’s really unexpected and surprising and really great.”
