i doubt shes a maniacal genius like youre suggesting....i would bank more on the fact that she was scared shitless and was in survival mode since she is used to her parents beating the shit out of her, and due to her disability it might be hard for her to process commands while someone is yelling at her and beating her....she says it was not the first time it happened, and she has publicly said she doesnt want her dad to go to jail, she just wants a court to force him to get help for his anger....it doesnt seem like a vendetta to me
