Supernatural 14x03 Sneak Peek "The Scar"

Yeah i have a theory that most people are not going to like because basically my theory is that Sam is going to go to the 'darkside' now many people are thinking that, there is no way cause its just too obvious but to bạn i say, what other way could the writers end this?

I know there has many indications this season that Dean may have an evil side to him as well, with his gần đây trip to hell and all that tourting but bạn know Sam is giving into the evil that was forced into him when he was a baby....
