"Supernatural" season 10, episode 3 spoilers are here and Jensen Ackles will return to the director's chair as Sam continues to have faith on his brother, Dean, who has been tainted with the Mark of Cain and is as destructive as ever.

The video clip released by CW Network revealed "Supernatural" season 10, episode 3 spoilers as it shows Demon Dean and Sam having a heart-to-heart talk. Of course, by this time the Mark of Cain has really been prodding the older Winchester into telling things he doesn't mean.

Sam has been pleading with Dean to come back to no avail. Instead, Demon Dean tells his brother: "I chose the King of Hell over you. Maybe I was just tired of babysitting you, or always having to yank your lame ass out of the fire since forever."

But Demon Dean is not yet finished as he pins the death of their mother on Sam as he says, "Maybe it was the fact my mother would still be alive if it wasn't for you. It's your very existence sucked the life out of my life."

Although Sam knows that's not his brother talking, those words cut deep so it remains to be seen just how much they will affect Sam.

By this time, Crowley realizes that he couldn't control Demon Dean so he devises another plan and is seeking the help of Castiel, of all people. Just how that alliance will play out would be something to look forward to for the fans.

According to the "Supernatural" season 10, episode 3 spoilers, through the synopsis released by the network: "Sam (Jared Padalecki) continues his efforts to save Dean (Jensen Ackles) from the Mark of Cain. Crowley (Mark Sheppard) realizes Dean's demonic antics are starting to cause problems for him in Hell so he searches out an unlikely ally - Castiel (Misha Collins)."
