The tenth season of 'Supernatural' will explore on the demonic state of one of the Winchester brothers, Dean.

Jared Padalecki, who portrays the younger Winchester brother, said in an interview that "the final 30 seconds of the finale ... certainly sets up what's going to happen with Season 10." He also said that the tenth season tackles on Dean's reincarnation as a demon.

Reports said that Dean will encounter difficulties coming to terms with the fact that he has become a demon, which is the nightmare he feared the most. Dean's demonic power could also be too powerful. Dean has the Mark of Cain, which holds some secrets like power that he had against other demons.

It is still unknown what could be the effect of the Mark of Cain to Dean. Even the actors are looking forward to where the story leads.

"There is a possible way, which might be the way that ultimately Sam saves Dean. I don't know that there's another way that we've introduced on the show. Granted, there might be another way. He might get Crowley to talk, he might get another demon to talk or maybe Castiel's got some new-found power with Metatron and his situation. I don't know. There are question marks there about what are going to happen, but there is definitely an option on the table," "Supernatural" reports cited actor Jensen Ackles.

The brotherly love between the Winchester brothers could save Dean from his current state. Actor Jared Padalecki believed that the brothers will remember their finale reconciliation and will be constantly there for each other. "You see in the finale a lot of what makes Sam and Dean 'Sam and Dean. There's a lot of that brotherly love that the show is based on. So hopefully next season we bounce off of that," Jared told TV Line.

"Supernatural" season 10 is set to air in October at the CW Network.
