Somewhere inside, she wishes to be saved. Curse of "Song": The fear that "if I can't sing, I'll be thrown away" is burned into the base of her programming. She has a self-destructive side where she tries to force herself to sing even with a voice full of noise. She believes she is worthless.

No matter how kind Guest is, she thinks, "There must be an ulterior motive," or "This is just a prelude to getting bored and throwing me away."
