Previously on 'Supernatural' Dean finally got the chance to come face-to-face with Cain. Not only that, the older Winchester brother managed to kill the Biblical character using the First Blade. However, he was soon taken aback when Cain revealed to him that the mark of Cain will just lead him to killing his own brother. Aside from looking for means of getting rid of the mark, Dean also has to work on a new murder case with Sam. But the new mysterious killer will not be easy to identify. Cole, who is returning tonight, will even be the target of this infectious murderer. Watch 'Supernatural' season 10 episode 15 online through the free online stream link at the bottom.

Actor Jared Padalecki recently gushed about what's to come for his character and Dean. "Sam knows his brother very well and he knew when he saw Dean's face after Dean had gotten rid of Cain - but still had the Mark - that Dean was not okay," Padalecki said. "Sam's been down in dark places and Dean has always helped him through, so I know, selfishly, Sam doesn't want to lose his brother, but unselfishly, Sam would like to help his brother the same way that his brother's helped him many times." He also dished, "Dean is trying to pawn it off like, 'Demons lie and you just said that to get under my skin.' So I think Dean is trying to ignore it, but of course, it's swirling around somewhere in the back of his brain."

The official synopsis of 'Supernatural' season 10 episode 15 reads: "Despite Dean's (Jensen Ackles) directive to forget about looking for a cure for the Mark of Cain, Sam (Jared Padalecki) continues to do research. Dean suspects Sam is hiding something but decides to focus on a new murder case where they run into Cole (guest star Travis Aaron Wade). The three team up and learn a Khan worm is infecting men and turning them into murderers. Unfortunately, the worm makes it's way into Cole"
