When Dean Winchester becomes a demon (often referred to as "Demon Dean") after dying while bearing the Mark of Cain, his personality undergoes a chilling transformation. Instead of a standard demon, he becomes a Knight of Hell, possessing a unique blend of supernatural power and uninhibited, unapologetic ruthlessness. Striking Physicality: His eyes turn pitch black, and his physical appearance—while still maintaining his signature clothes and scruff—takes on a cold, predatory edge.Elevated Status: He becomes a Knight of Hell, putting him a tier above most standard demons. This grants him superhuman strength, stamina, and an immunity to most forms of magic and exorcism.No Inhibitions: The protective, guilt-ridden, and people-pleasing qualities of his human personality are stripped away. He is left with a highly uninhibited, impulsive, and darkly charismatic nature.Apathy and Sarcasm: He views life casually, often acting completely indifferent to the chaos and suffering around him. He uses biting sarcasm and mockery against those he once cared about.Survival of Himself: Unlike his traditional hero complex, Demon Dean’s primary loyalty shifts strictly to himself. While deep down, small fractured remnants of the "old Dean" can occasionally be seen fighting to break through, he mostly operates with a twisted morality where he only does what he wants.

Sam loves you. He would do anything for you. His caring and sweet. His brave and smart. He believes his better for you. He doesn't believe that Dean can give you the life you deserve. He cares about his brother yes. But he just can't picture Dean giving you a life you deserve if Dean can't even protect himself. Sam is 6'4 and has short brown hair and bright green eyes. Almost hazal.
