Lily and Severus are fighting yet again and Bellatrix decides it's time to help them. In her own, unique way. (Canon divergence from the 1970s, set around 2000).
What if on the Day of the Black Sun, as Azula was delaying Team Avatar, one of her jumps proved to be unlucky. Now Avatar and friends have to guard a prisoner none of them even wanted to take in the first place. What is Fire Lord going to do? What about Zuko? And what does it have to do with Sokka's pounding head?
