Supernatural Season 10 Spoilers: What's Next for Dean and Will Cole Return?

Dean is no longer a demon on Supernatural, but he still has that pesky Mark of Cain burned into his skin. So what's next for the elder Winchester brother, who underwent a major transformation this season?

The "Matt's Inside Line" column" at TVLine has the answer.

"I absolutely loved the opening scene of last week's Supernatural, with Sam and Dean (with shades on) overlooking the lake. But even through the end of the episode, Dean was surprisingly (and a bit disappointingly) cool and put together, post-Demon. He's goanna explode or have an emotional meltdown soon...right? -Audrey
Considering the Mark of Cain is still haunting the elder Winchester, that is a strong possibility. In fact, the pesky problem is going to take up a lot of storyline real estate going forward. 'You're going to see Dean dealing with this pretty much for the next chunk of the season, as he and Sam take different paths in how to deal with it,' executive producer Jeremy Carver teases. 'While we're all very happy he was cured of being a demon, there's a lot more work to be done.'"

The column also has some information about Cole, the man who wanted revenge on Dean only to have the demon beat him to within an inch of his life.

"I was so not expecting Supernatural's Dean to go so far with his kill-Sam campaign! Now that human Dean's back in business, how long until someone brings up that pesky Cole is fluttering about? -Sam (no, not that one)
EP Jeremy Carver responds, 'Who's to say Cole resurfaces...? But if he did, that would be a heck of a confrontation. I'm looking forward to it as much as you are.'"
