Supernatural season 13
Jared Padalecki and Jensen Ackles as Sam and Dean in Supernatural The CW

Supernatural season 12 will bring new challenges for Winchester brothers, Sam and Dean, when it premieres on 10 October at 9pm EST on The CW network. The brothers were separated in the season 11 finale, with Sam getting shot by Toni Bevell of Men of Letters and Dean spotting his back-from-the-dead mother, Mary, in the woods.

Executive producer Robert Singer talked to TV Line about what is next in store for the Winchester brothers. He teased that "Sam's going through hell with the British Men of Letters" who have captured the hunter According to the producer, Sam is convinced that his brother died saving the world. "As far as [Sam] knows, the bomb blew up, and that's what saved the world."

Jensen Ackles (who plays Dean) added that Sam "has no reason to believe Dean would even be coming for him." But the actor also teased that his character will quickly figure out Sam's whereabouts and teased about incorporating certain Liam Neesan lines from the Taken movie.

"Dean's got to figure out quickly what has happened, where he is, and then it turns into a bit of Taken," Ackles teased, and revealed that there's even a direct shout-out to Liam Neeson's famous "I will find you" line from the film franchise.

Sam and Dean will not be separated for long, confirmed Robert Singer. Sam's rescue mission "doesn't take up too many episodes – we get that over with pretty quickly – but they're action-packed, and all our characters are involved," Singer said.

Previously, appearing at San Diego Comic-Con 2016, Bob Singer promised that Supernatural is going "back to basics" in season 12, after showcasing a fight between God and Darkness in season 11. The show in its 12th season will bring the focus back on the Winchester family. Sam and Dean will be seen dealing with the return of their mother, Mary (played by Samantha Smith), the threat presented by another branch of the Men of Letters, and Lucifer's whereabouts.

"You don't get bigger than God, we can't top all that," Singer pointed out, admitting that they're aiming to "tell smaller stories — some good old fashioned horror stories" in Season 12. "We've introduced the British Men of Letters, they'll be part of what we're doing. And we've still got Lucifer out there, so there's a hunt for Lucifer." The show has cast Rick Springfield to play Lucifer's vessel in season 12.

Misha Collins who plays Castiel, revealed at the panel that his character is reverting to his season 4 iteration in terms of attitude. He teased, having got "much of his mojo back... he's angry and he's in a fighting spirit and he's after Lucifer. And now that Mary's back, he's tattletaling a lot."
