According to Deadline, which first broke the news, the premise for the potential offshoot — tentatively titled Wayward Sisters — will be introduced in a Season 13 episode of Supernatural. Here’s the conceit: Sheriff Mills (played by Rhodes) and a group of troubled young women, all of them orphaned by supernatural tragedy, will team up as a supreme monster-fighting force.
“Unlike the original series, which centers on a biological brothers, Wayward Sisters is about a sisterhood of girls in a foster family,” Deadline reports.
The project is being shepherded by Supernatural writers-producers Andrew Dabb, Robert Singer, Phil Sgriccia, and Robert Berens.

Deadline speculates that two existing Supernatural characters, orphan Claire Novak and runaway Alex Jones, could be featured in the offshoot alongside Rhodes (whose character was first introduced in Season 5).
Back in 2014, The CW developed a Supernatural spinoff billed as a “sweeping drama about the mafia-esque monster families that, unknowingly to humans, run the underbelly of Chicago and who are being tracked by a newly minted Hunter.” Titled Supernatural: Bloodlines, the project never made it beyond a pilot.
