Portrayal Difference
She has 2 personalities much like Springtrap, first is her normal animatronic self and the second, being in control by Elizabeth Afton. she speaks softly and acts gentle when on stage but during break time or in backstage, she becomes awkward and paranoid after learning that sometimes she couldn't do what she wanted or intended to do. she suddenly commits weird actions that may lead to danger, fully unaware what William programmed into her. but in spite of her different behaviour, her prudence remains. then she suffers seeing Elizabeth's spirit and possessing her. due to that, she begins thinking of getting rid of the spirit by herself. not only for her comfortness, but putting Elizabeth out of misery as well.

She was the one who freed Elizabeth instead of Henry in this timeline.
