Supernatural: Wayward Sisters was an attempted spin-off for The CW's Supernatural. The backdoor pilot is titled Wayward Sisters and it was the tenth episode of the thirteenth season. It aired on January 18, 2018.
On May 11, 2018, writer, Robert Berens announced that Wayward Sisters was not picked up for a series order.
Writer, Andrew Dabb also took to social media to express his disappointment of the decision. "It breaks my heart to say this, but CW has chosen to pass on Wayward Sisters. We love these characters, and have spent almost two years trying to make this show a reality on the network... but there are some fights, sometimes, you can't win. I want to thank everyone involved in this entire process, from our fantastic crew, to our amazing cast, and, most of all you. Your passion for this idea fueled us, and we wanted so much to make this happen for you. I'm so sorry we couldn't. But know that these characters will live on. We owe them, and you, and us that. Thank you." 
On May 14, 2018, a Twitter account by the name of Wayward Daughters announced their plans to save Wayward Sisters by flooding The CW page, Netflix page, and any other related pages with messages, posts, tweets, etc. on all social media platforms on May 17. This is the corresponding date of the season 13 finale of Supernatural. This is in hopes of forcing The CW to reconsider its decision and, if not, convince Netflix to pick it up.
CW president Mark Pedowitz defended his decision by stating “We had really great material this year. We’re really excited about the five series we did pick up. We are big fans of the characters and the women who played the characters in the series, but we did not feel creatively the show is where we wanted it to be. We felt we had a better shot with Legacies.” Pedowitz continued to say that CW execs are “big fans” of the Wayward actresses “and hope they continue on guest starring on Supernatural. 
It tells the story of Sheriff Jody Mills (Kim Rhodes), Sheriff Donna Hanscum (Briana Buckmaster) and a group of troubled young women, all of them orphaned by supernatural tragedy. Under Mills' training and protection, the women will emerge as a supreme monster-fighting force. Unlike the original series, which centers on biological brothers, Wayward Sisters is about a sisterhood of girls in a foster family.
