the black hair girl yes split personality the red haired bitch though it just that a bitch she used the black haired girl as a means of passing the time or in other words as a play thing nothing more nothing less really at least that is what i have been able to gather of the relationship between the two of them anyway
I think both the red hair girl and the black haired girl have received some trauma due to the incident and their brains dealt with the stress in different ways. Like the black haired girl has a split personality and the red haired girl is now in denial.
