With the new Supernatural season beginning next month, the network just unveiled the first preview showing Dean and Sam together and the premise for the new season.
The prophet of God returns, hiding out in a church, apparently free from Crowley and he's not too happy about that. Mystery still surrounds the whereabouts and motivations of Castiel, who was also trapped in Purgatory with Dean.
As I have surmised before, this season revolves around demons and Crowley. The Leviathans were defeated using information from a tablet, which is the word of God. There are other tablets hidden around the world and the Prophet knows where one can be found. Unlike the other, which dealt with Leviathans, this one deals with demons.
