The CW is mounting yet another attempt at a Supernatural spinoff.

It has tapped the show's favorite Kim Rhodes to star in a potential spinoff of the long-running genre drama, The Hollywood Reporter has confirmed.

Titled Wayward Sisters, the backdoor pilot will air as a planted episode in Supernatural's forthcoming 13th season. The potential offshoot tells the story of Sheriff Jody Mills (Rhodes) and a group of troubled young women, all of them orphaned by supernatural tragedy. Under Mills' protection, they emerge as a supreme monster-fighting force.

In a change from Supernatural — which revolves around the Winchester brothers, the spinoff follows the sisterhood of girls in a foster family. The spinoff is also expected to bring over other characters from the flagship as well as introduce new ones. The title is a nod to the song used in Supernatural finales — Kansas' "Carry on Wayward Son"

Supernatural showrunners Andrew Daab and Robert Singer will pen the script and exec produce alongside the flagship's Phil Sgricca and Robert Berens. The project hails from Warner Bros. Television. The CW and WBTV declined to comment.

Wayward Sisters marks the latest potential spinoff of Supernatural. During the show's ninth season, backdoor pilot Bloodlines — which explored the hunter versus monster culture in Chicago and featured only new characters — was introduced but that project did not move forward. Wayward Daughters originally started as a fan campaign two years ago. It has gained support from the Supernatural cast on social media.

In the years since Bloodline did not move forward, CW president Mark Pedowitz has been asked — pretty much every year during his time at the Television Critics Association — how long Supernatural would run and if the network would try again with another spinoff. He has maintained the same party line: the flagship would run as long as stars Jared Padalecki and Jensen Ackles want to continue to do the show and that if a natural idea for another spinoff came to fruition, he would of course try again.

Spinoffs continue to be all the rage on the broadcast and cable networks. In the so-called Peak TV era of more than 455 scripted originals, spinoffs are cheaper to market and come with a built-in fan base, helping networks cut through the cluttered landscape. Already in the works for the 2017-18 broadcast season is another Grey's Anatomy spinoff as well as a Big Bang Theory prequel series.
