The official synopsis reads as follows:

Jensen Ackles in a new interview talks about Dean Winchester's struggle with the Mark of Cain and what to expect in the upcoming episodes.

Ackles told The Hollywood Reporter: "Clean Dean" is what I call him, but the spoiler alert is that it doesn't last that long. As we will see in the next episode, he starts to teeter a bit. It's kind of against his fabric; it's against his code; it's not who he is."

"And sure, he can clean it up a little bit, but at the end of the day, he's a burger-and-fries kind of guy, so I think the mentality of wanting to get a clear head and wanting to make some new life choices is a good thing, and that will continue to carry on, but from an audience's perspective, I like my Dean a burgers-and-fries-and-beer kind of guy!" he added.

Jensen also praised Dylan Everett who plays a young Dean in this week's Supernatural installment.

"He (Dylan Everett) knocked it out of the park," Ackles said and added, "Here's a kid who's played a young version of Dean before, but it was Young Dean, and here and now he was challenged to play Present Dean in a younger body, and to come onto a set and to take on a character that's been portrayed by another actor for [so many] years, and to put in the performance that he did.

"I as an audience member and as a huge fan of the show and as someone who is highly protective of this character that I have been playing for the past 10 years, I was very impressed, and I was very pleased," he added.
