Fans should be prepared for some major changes in the world of “Supernatural.” Cinema Blend is reporting that Jeremy Carver, the showrunner since season 8, is leaving after the finale of season 11. He will be replaced by Robert Singer and Andrew Dabb who’ll begin with season 12. Carver will instead focus his attention on The CW’s new show “Frequency,” reports TV Line.

This is not really a cause for serious concern as Robert Singer has been a producer, writer, and director on “Supernatural” since season 1. Cinema Blend notes that the much loved Bobby Singer character was even named after him. Also, this isn’t the first time there was a showrunner change on “Supernatural.” Eric Kripke was showrunner from season 1 through to season 5. Sera Gamble took over in season 6 and left after season 7 ended. However, there has never been dual showrunners on “Supernatural” before. So, it’ll be interesting to see how their dynamic affects the course of a show that has been running for more than a decade now.

As for Andrew Dabb, he joined “Supernatural” in season 4 as a producer, writer and is now co-executive producer, notes Cinema Blend. It’s definitely a good thing that Singer and Dabb are insiders, having a lot of experience writing the stories and the characters. They also know the pulse of the fans. So they hopefully wouldn’t do something drastic that alienates the viewer base. But sometimes, changes can be a good thing. The two showrunners may have plans that can take “Supernatural” to exciting directions hitherto unseen.

If season 12 is the last one for the Winchester brothers, then the showrunners could definitely do something similar to what actor Jared Padalecki said in an interview with Entertainment Weekly. “Part of me, loving Butch Cassidy and the Sundance Kid, always thought it’d be great to see the boys against insurmountable odds and to freeze-frame on them and just hear stuff in the background. You don’t know if they die, you don’t know if they live, but you know that they’re going to go out in a blaze of glory.” That would be a great ending, perhaps even accompanied by a great country song.
