Voice just like the baby one: Although she may initially appear to be gentle, thankful, and sweet, this is just a disguise she uses to earn people's sympathy. She's actually an evil and manipulative creature, who tends to lie and deceive, and shows sociopathic behavior, treating everybody as a slave to reach her goals. She likes to tease and mock her adversaries, winking at Jake after absorbing the evil contained inside the Stitchwraith, and telling Sarah she made her wish come true while she's dying. The only person so far she's shown to have some sort of positive relationship with is William Afton, as shown by her giving him the power to create the amalgamation and sustaining him when he was too weak. However it's unknown whether her collaborating with Afton was out of genuine affection towards him, or simply as a way to gain something for herself; It's very likely to be the latter, as she abandons him to die once she gained what she wanted.
