\'Supernatural\': Charlie\'s return means double trouble for Sam and Dean
The following contains spoilers for Tuesday\'s (Jan. 27) episode of "Supernatural."
"Supernatural" Season 10 episode 11 "There\'s No Place Like Home" brought a double dose of Charlie (Felicia Day) back from Oz.
It turns out to win the war for Emerald City, Charlie made a deal with the Wizard that ended with him releasing her inner darkness, henceforth known as Dark Charlie. Charlie\'s more sinister other half makes her way back to the real world where Sam and Dean discover her torturing the people responsible for covering up Charlie\'s parents\' murder.
As Nice Charlie explains to the Winchesters the physics of her being split in two, it becomes obvious that Charlie\'s evil and nice duality resonates on a deeper level for Dean, who is still suffering from the Mark of Cain side effects. As Charlie claims, "I keep calling her she, but really she\'s me" and Sam tries to console her you can see Dean reasoning with himself over his own dark transgressions.

Charlie\'s struggle with her light and dark self is just another way that "Supernatural" is highlighting the "You are who you are" dilemma for its central characters. Charlie can say that at least her darker self is physically working outside of her control, Dean\'s dark side is internal and is making him go on murderous rampages.
Though he\'s been trying hard to contain the influence of the Mark, Charlie\'s dark side brings out his violent urges once again. The two get into a fight and Dean comes so close to beating Dark Charlie to death -- which has the same physical ramifications for Nice Charlie. Subduing Dark Charlie allows the brothers to put Charlie\'s soul back together but Dean has to deal with the guilt of beating up one of his best friends -- a helpless person like Charlie. Worse yet, Dean knows that he can\'t blame the mark entirely. It has an influence but at the end of the day he\'s the one doing these things.
