There are just so many stupid points in that. Why was she there in the first place.
Why did he keep her there. Why didn't he restrain her. Why didn't she leave if she wasn't
restrained. Why not use a phone. Why allow her to go out to grocery stores etc where she
could talk to people etc etc.
Basically, she was having filthy sex with this guy when she was 14, and left to live with him.
They conspired to hide her until people forgot about her, so she could live with him and so
on. Then, at 24, she thought, ah, this is crap, I'm going home.
