Said Pedowitz to the Television Critics Association gather for their 2014 Winter Tour, “As a fan of the show, who’s seen every episode, as long as I’m here and those numbers hold, God bless them. They can go as long as they want.”
In terms of the spin-off which will be set up in a backdoor pilot this season, Pedowitz was asked if that was still in play, and he replied, “Yes, very much so. It’s set in Chicago. Hunters, monsters… The script just came in.”
As for whether any of the main “Supernatural” characters would appear in the spin-off, which will be centered around new characters, Pedowitz said, “In the spin-off episode, they’d be in it. Whether they’re in the series… For me, for spin-offs to work, you have to stand them on their own two legs, so you can only do those crossovers when the time is right, like we did with ‘The Originals.’ We didn’t see Michael Trevino’s character, Tyler, until the seventh or eighth episode. By that time, the show was standing up on its own two legs.”
