Warning: This article contains spoilers for Supernatural .
Recently, Supernatural has seen drama on a massive scale. There was Castiel’s struggle with his host’s former life and the troubled Claire Novak, Dean’s Mark of Cain, the arrival of Rowena — well, the list is exhaustive. All of these subplots will begin to come to a head, when Supernatural returns from its brief hiatus on April 15, and the return of Charlie in the 18th episode will launch the changes. And things are going to change in such a way that many Supernatural fans will be left in jaw-dropping awe.
The plot summary for Supernatural ‘s next episode gives fans just a hint of what may be coming for the Winchester brothers in the episodes leading up to the tenth season finale.
“Charlie (guest star Felicia Day) calls Sam (Jared Padalecki) and Dean (Jensen Ackles) to tell them she found the Book of the Dead which could help remove the Mark of Cain. The Winchesters race to her after she tells them she’s been shot by a man named Jacob Styne (guest star Jeff Branson) who says the book belongs to his family and he won’t rest until he gets it back.”
This single-episode summary is foreboding enough for Supernatural fans, but Jared Padalecki has added more intrigue to the remainder of Season 10. Mr. Padalecki told fans at a recent Seattle Supernatural convention that fans can expect something that hasn’t been seen for several seasons of Supernatural .
Sam will go dark.
“Sam does have a lot of darkness in him, so does Dean. I think it’s one of the themes that, as long as Supernatural is alive, that theme is going to be around. Both of these guys are struggling with their demons, struggling with their past… I think we will see Sam get dark. I know we do a little bit this season that you haven’t seen yet. So I think you’ll see it from Sam and Dean both.”
Sam may not go total dark-side, but it seems he will make good on his promise to do whatever it takes to rid Dean of the troublesome Mark of Cain. Padalecki, who has admitted to struggling with darkness in his own life outside of Supernatural , said that they are currently in the middle of filming the final arc of Season 10. Jared added that he couldn’t remember Supernatural ending a season on such a tense note since Season 5 or 6.
The darkness will spread throughout the characters of Supernatural. Cain has already made his intentions clear to murder Crowley, Castiel, and Sam in classic Supernatural style, but we also know that the only known cure for the Mark would force Dean to murder his own brother. There doesn’t seem to be any way around it. Supernatural cannot end without spilling blood.
Supernatural airs Wednesdays at 9pm on The CW network.
