It's fascinating that she retain innocence on sexual stuff (not even knowing what a condom is assuming she wasn't lying), while she's capable of threatening a man with a knife to have sex with a person he drugged. I wonder when she started having feelings for her dad, but it's getting more clear that her mom didn't also help, especially if she use drugs and react pretty bad to dad or to her brother as soon as she's in love with him her feelings will be amplified by: mom doesn't love dad, mom doesn't deserve him, she always treat him bad, she also injured borther, she must not like them. On top of her having the electra complex which would take her feelings to the extreme.
