‘Supernatural’ Season 10 Spoilers: Demon Dean Will Be Main Storyline, Premiere Features ‘A Lot’ Of Singing And Dancing!

"Supernatural" season 10 spoilers reveal that Demon Dean will be the main storyline, and that the premiere will feature "a lot" of singing and dancing! On Sunday, July 27, the "Supernatural" Comic-Con 2014 panel featuring Jared Padalecki, Jensen Ackles, Misha Collins, Mark Sheppard and executive producer Jeremy Carver revealed new spoilers for season 10.

According to Carver, Demon Dean will drive the "Supernatural" season 10 storyline, Zap2it.com reports.

"It has an enormous effect on the season and the brothers," Carver said. "The boys, Sam in particular, will really dig into how to rescue his brother from being a demon while Dean struggles with what it means to be a demon. We're really excited, most of all, with the brothers questioning who's the real monster. It's exciting, moving, very emotional and fun."

Ackles added that this isn't a demon possessing Dean - this is still Dean, but Demon Dean.

"A lot of times on our show we have demons possessing a meat suit, which is lovingly what we call it on this show. This is not like that. This is actually Dean's soul that is twisted," Ackles said. "It was interesting trying to make it the same character but a different character, just twisted and demonic."

Ackles also revealed that the "Supernatural" season 10 premiere will feature "a lot" of singing and dancing!

"There's a lot of singing and music this year," Carver admitted. "And a little rump-shaking."

Ackles added, "Apparently Demon Dean likes to karaoke."

However, don't think this means Demon Dean and Crowley will get along.

"I think nobody's ever going to believe that Crowley didn't know what was going to happen, right?" Sheppard said. "So we'll have to see if Crowley has any control over what happens or if Crowley's even in charge. We'll have to see."

"With Demon Dean, at some point Crowley is going to be like, 'This was a bad, bad idea,'" Ackles said.

"Supernatural" season 10 premieres Tuesday, Oct. 7 at 9 p.m. ET/PT on The CW.
