The long-running Warner Bros. series, Supernatural, which is now airing on The CW, is getting a new season — and a potential spinoff! A backdoor pilot, Wayward Sisters, will air as an episode of Supernatural‘s upcoming season. All of the details were dropped during San Diego Comic-Con.

Wayward Sisters is written by Andrew Dabb and Robert Berens, who will executive produce along with Robert Singer and Phil Sgriccia. Centered on the character of Sheriff Jody Mills and a group of troubled young women – all orphaned by supernatural tragedy – these “wayward sisters” emerge as a formidable force against the supernatural, under Mills’s training and protection.

Clark Backo, who recently appeared in ABC’s Designated Survivor, will portray the new character, Patience Turner. She’s described as “a high school over-achiever whose life is turned upside down when she discovers she’s a powerful psychic, a gift she inherited from her estranged grandmother (and season one Supernatural character) Missouri Moseley. Hunted by dark forces for her power, Patience finds refuge with Jody and her wayward family.”

Missouri Moseley was notably portrayed by Loretta Devine in the first season of Supernatural, and Devine is confirmed to be appearing in a Supernatural episode this upcoming season.
