Supernatural's Dean Winchester will raise a little hell during the first few episodes of season 10, but fans will have to wait until episode three to see the new demon confront his little brother.

The CW drama dropped by the 2014 San Diego Comic-Con on Sunday, and Jensen Ackles (Dean), Jared Padalecki (Sam), Misha Collins (Castiel), and Mark Sheppard (Crowley) teased a packed Hall H about one of Supernatural's most intense seasons yet.

When Demon Dean does meet Sam for the first time, Give Me My Remote promises the brothers will have their weapons drawn as they battle it out - a fight that will end up with the older brother tied up for a large chunk of the episode ("Soul Survivor"). Even worse, the demonic Winchester won't be taking care of Baby quite as well as his human self.

"It's fun... Fun's the wrong word... It's exciting and very moving and emotional," said executive producer Jeremy Carver, according to Variety.

Luckily for Dean, Variety reports that Cas will ignore his own fading grace and try to help Sam patch up his brother as the season kicks off.

Meanwhile, Crowley will be enjoying his new pal, even if he does become a little too much to handle.

"I like Demon Dean...Demon Dean is the best thing that's happened to me," Sheppard said, according to Give Me My Remote.
