“Nessarose is a strong-willed semi-invalid,” said Elphaba. “She’s very smart, and thinks she is holy. She has inherited my father’s taste for religion. She isn’t good at taking care of other people because she has never learned how to take care of herself. She can’t. My father required me to baby-sit her through most of my childhood. What she will do when Nanny dies I don’t know. I suppose I’ll have to take care of her again.”
