Azula sat on her bed. The cell was cold and dark, and she had only a thin blanket and a nightgown to keep her warm. She huddled up, summoning a tiny orange flame to warm her hands. She thought about how she'd gotten here. She'd tried to kill the Avatar and her own brother. Zuko, the new Firelord. She felt an old wave of disdain wash over her, but then it was pushed away by regret. Why did I attack him? Why did I try to kill the Avatar? Why did I try to dominate my country? Azula pondered those three questions and then came up with the answer.
Love. She wanted her father to love her more than Zuko, wanted her father to look at her and say, "Azula, you are the best daughter I could ever have." Azula, like many other children, wanted love from somebody who was incapable of giving it.
