David Cage cast her in the video game Beyond: Two Souls.

To get her on board, he approached her with a scrapbook of real childhood pictures of her and some that were computer generated. She didn't know where he got some of her photos.

Then she found out, in his obligatory main character shower scene (one he has for every game), that the model they used, while not scanned from her body, had the naughty bits fully rendered in the core assets.

I'm convinced, mostly as a joke but somewhat seriously, that David Cage creep'd on her so hard it turned her off guys for good.

Her turning into a dude may be a way to cope with the trauma of dealing with David Cage and his weird french-ness.

Keep in mind, I'm only halfway serious here but I wouldn't doubt it had some effect on her psyche.
