The original fan-proposed series, Wayward Daughters Academy, featured Mills and Donna running an academy for young women.
In addition to Mills, Wayward Sisters will feature other characters from Supernatural, with Claire Novak, Alex Jones and Donna Hanscum as the most likely candidates to appear.
A new spin-off Wayward Sisters will air as a backdoor pilot during the drama’s upcoming 13th season, Deadline reports.
The CW is trying to their hands at a Supernatural spin-off once again.
