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

The first promo released for Supernatural season 12 features the return of Winchester brothers but not united. The video features Dean, Mary and Castiel teaming up to find Sam, who was last seen getting shot at by a Toni Bevell of Men of Letters.

The video opens with Dean asking, "Where is Sam?" and in the next we see Sam tied in the trunk of a car. Then we see a scene where Castiel tags along with Dean as the angel asks, "you brought your mother?" The newly resurrected Mary Winchester will help Dean in his effort to find Sam.

Mary is seen having a conversation with Castiel where she explains, "Right now all that matters is getting Sam back!" as the young Winchester is seen tied at a chair and is tortured by Bevell. The 20-second video also features guest star Rick Springfield as Vince Vincente, aka Lucifer's new rock star vessel, butting heads with King of Hell Crowley.

Previously, showrunner Andrew Dabb dished to TV Line about Mary Winchester's past. He said, "The story's always been, 'Once Mary married John and settled down, she stopped hunting,' But we're going to find out maybe that's not the whole story."

According to actor Jensen Ackles, who plays Dean, Mary Winchester will be haunted by her fiery demise and "the ripple effects" of her death. Since her passing away sent her two sons down a hunter path, which she didn't want and this realisation is "going to be difficult for her to process."

Jared Padalecki, who plays Sam, added, "Sam blames Dad for all the hunting stuff, but really, you could argue it's Mom's fault. She was the hunter. It was the Campbell family, not the Winchester family. It wasn't her fault, but it was her lineage that led us to where we are now."

However, according to the actor, Sam may not want to see his mom hunting again. Padalecki said, "The boys know that this is their life, this is what they're good at [and] this is the way they can best help the world," and noted that "we're going to see Sam probably not want his mom to go out and hunt."

"It's my mom, man! I don't want to see her get punched or shot or bit by a vampire!" the 34-year-old actor added. Supernatural season 12 premieres on 13 October on The CW Network.
