"Supernatural" has already been renewed for a 12th season, which at the very least can only mean that fans can savor another year of the Winchester brothers fighting paranormal bad guys. But news of a replacement behind the scenes has plagued the show recently. Will a change in showrunner affect the storyline?

It was previously reported that Jeremy Carver, who served as the hit series' showrunner from season 8 onwards, is resigning from his post to focus on a different The CW show. Robert Singer and Andrew Dabb, both long-time "Supernatural" collaborators, are set to replace Carver.

It should be noted that Singer and Dabb are veterans in the game, with the former having experience directing and writing for the show and the latter writing and serving as a story board editor. Both of them have executive-produced the series.

Numerous reports say that with the latest change in showrunner, "Supernatural" may be more different in the upcoming season. The show has been on for more than a decade and it's understandably difficult to continuously come up with new material each year. Two showrunners may just prove to be a good move.

While the show has been renewed for a twelfth season, nothing has been announced if it will be their last. However, when the inevitable end does come around, stars Jared Padalecki and Jensen Ackles have their own respective takes on how the series should conclude.

"If you'd asked me season 1, I would've thought that it would've been the apocalypse. But then again, you can't end the TV show with the worst thing happening," Ackles told Entertainment Weekly. "As we've evolved, I think that there's different roads that the show could certainly go down that would be interesting. I think we've taken some really good turns."

On the other hand, Padalecki has it more figured out. "It's changed a lot over time. 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," he described.

As for the highly-rumored "Supernatural" spinoff, the possibility of such a thing happening was recently addressed by CW president Mark Pedowitz. Without denying it, Pedowitz told Variety, "We're open to listening." Given that it's not exactly a confirmation, fans can only hope for the best.

In the meantime, fans can catch the "Supernatural" season 11 finale, titled "Alpha and Omega," which will show God's decision, on Wednesday, May 25 on The CW.
