The devil will strike a deal with the most powerful human being on Earth in the upcoming episode of "Supernatural" season 12.

In episode 8, Sam and Dean, together with Crowley and Rowena, will try to run after Lucifer as they try to prevent him from carrying out his evil plan. Based on the synopsis for the episode, Lucifer will look for a new vessel after escaping from rock star Vince Vicente's avatar in the previous episode. This search will lead him to the White House.

It can be recalled that in episode 7, Rowena destroyed Lucifer's vessel. However, the Devil was able to heal himself by transferring to the body of a renowned rock star.
