After 15 seasons, Supernatural has finally come to an end, definitively concluding the monster-hunting adventures of fan-favorite brothers Sam and Dean Winchester. While series creator Eric Kripke ended his time on the show with the fifth season finale in 2010, the executive producer observed that he knowingly left enough room for the series to continue, albeit not expecting it to run for another decade. After star Jensen Ackles and showrunners Andrew Dabb and Bob Singer pitched him plans for the series finale, Kripke gave the creative team his blessing.

"I think it's the best possible ending for the show," Kripke toldh EW. "They pitched it to me and I went off to think about it for a couple days, and admittedly, me being me, I spent some time thinking, 'Okay, is there any other ending I would pitch back that I think is better?' And I spent a couple days trying to chase down a couple avenues and couldn't come up with anything better. So I went back and I was like, 'Guys I think it's the right one.' There's some substance to it but there's something emotional, I think there's a positive energy around it."

Kripke revealed there was one scene he had in mind that he would have utilized if he stayed on to helm the series finale, without divulging specifics. However, in keeping with the series' overall horror premise, Kripke noted his conclusion would have been considerably darker than how the show actually concluded and would have likely earned a decidedly more mixed reception from the fans hoping for a happy ending.

"There's only one scene that I haven't done that I would've done for the end of the show and I'm certainly not going to give it away, maybe one day I will," Kripke teased. "But I can assure the fans that my ending was so much darker than the ending they're going with, so anyone who's like, 'Kripke should've ended it,' I'm like, 'You would've hated my ending!' Because it was a horror movie and it was going to have a horror movie ending, so I can promise you the ending [they went with] you'll love much more than if you had let me end the show."

Supernatural stars Jared Padalecki, Jensen Ackles, Misha Collins and Alexander Calvert.
