Charlie never thought she would become a monster hunter until she met Mel Winchester and they became instant friends. Then, she met Mel's brothers, Dean and Sam, and she became part of the family. She traveled on a long and grueling journey with the other three, but she never gave up hope that they would complete their mission. All three of them accepted Charlie for who she was, despite the fact that she was half demon and half angel. They knew she could be dangerous, violent, psychotic and impulsive almost on reflex, and they knew this all too well. But even though they were given countless warnings to just ditch her or walk away, they never abandoned her, no matter what. They genuinely cared about her and they saw that she had been mistreated far more than someone her age should have endured on her own. They also saw that Charlie had been sorely misunderstood with nearly everyone she came into contact with. To Charlie, they were a safe group of people she knew she could trust if she ever needed anyone. And she deeply cared about them more than pretty much anything else, more so than even herself. But, when a dark shadow looms over Charlie in the shape of her past, an old family member turned enemy reappears to make her life Hell. Can Charlie overcome her weaknesses, mistakes and fears in order to protect her newfound family? Or will she be forced to make a necessary sacrifice for the sake of others that she truly cares about?
