Rosemary Willits was a perfectly normal girl. Until she was possessed by the ghost of a catholic priest, Robert Wagner, when she was five.
And her psyche shattered.
She's insane... but she does not have Disassosiative Identity Disorder. She has Robert.
And Robert's not so bad. When he takes over, she's downright lucid. When he "sleeps", she tends more towards chaos and destruction.
BWA HA! I finally did her hair right! *dances*
