Dean (Jensen Ackles) will travel back in time to find the long-lost weapon that can defeat Amara (guest star Emily Swallow) in the upcoming episode of the long-running The CW series "Supernatural."
In "The Vessel," CarterMatt reports that Dean believes he can locate Hand of God, the only weapon capable of killing the Darkness, by going back in the past. It was last sighted in 1944, when it was sunk by a submarine deep in the sea. Dean will ask the help of Lucifer (Mark Pellegrino), who is currently using Castiel's (Misha Collins) body, for a favor. Only the Prince of Darkness has the power to make time travel possible. Upon seeing the wisdom of Dean's words, Lucifer will agree to help out. He also realizes that having the weapon handy will be a big boost in his quest to take down Amara.
Sam (Jared Padalecki) does not agree with his brother's plan, as shown in the promo. Time travel is extremely dangerous. Anything can go wrong with people who meddle with time. Based on the clip, Sam's worries are justified, when the fated submarine started to take several hits while Dean is still inside it. The older Winchester brother has just started explaining to the shipmates that he is from the future when a huge explosion rocks their vessel. Will Dean make out of the sub alive? What is Lucifer doing to Sam that makes him scream like that in the promo?
Meanwhile, the teaser also shows Cowley (Mark Sheppard) in the mercy of Lucifer. It appears that he is being kept in a small pen as punishment. Castiel/Lucifer also thinks putting chains in the demon's neck is funny. When Crowley is summoned for a brief chat, he sees Castiel/Lucifer commanding a number of demons in black suit. Crowley is angrily berating the other demon for daring to do that to him.
Supernatural" season 11 airs Wednesdays at 9 p.m. EST on The CW.
