Sophia blames him for everything.
She hates him for making her go out the night her parents were killed.
She slurs his name when her emptiness can't be fixed by the bottle or pills.
She despises that fact that she looks for him in every man that comes through these halls.
She doesn't understand how a person can pick up and leave without a trace.
Sophia Dennison met Dean Winchester when she was a silly, sixteen year old happened to stumble into her geometry class with nothing but a leather jacket and a smirk to die for.
Dean seemed to take an interest in Sophia, they would talk here and there in class and he would always walk with her to her next class before slipping out the back entrance of their school. One day, he slipped out and never returned.
When Sophia's best friend told her about a party one of the football player's was going to be throwing, she thought there would be a good chance Dean might be there. Upon arriving, she was ditched by her friend, handed one too many drinks and stumbled home to find both of her parents murdered in her living room.
And it's all Dean's fault.
