The Day of Black Sun, Part 2: The Eclipse
As the eclipse begins, Sokka, Aang, and Toph search for the Fire-Lord, but only find Azula in an underground bunker, who stalls them. When Sokka realises her plan, she provokes him by telling him of Suki’s capture. Zuko confronts his father in another bunker. He tells Ozai Azula struck down the Avatar, who is alive, that the Fire Nation only spreads fear and hatred, and in order to restore peace he will join the Avatar. Zuko refuses to kill Ozai as that is the Avatar’s destiny, not his. As he leaves, Ozai stalls him by revealing the events of the night Fire-Lord Azulon died. He had been ordered to kill Zuko, but Zuko’s mother sought an alternative, creating a treasonous plan for Ozai to take the throne, resulting in her banishment. The eclipse ends and Ozai attacks. Zuko redirects Ozai’s lightning back at him and leaves. Iroh single-handedly breaks out from prison before Zuko can join him. Aang is forced to allow his army to be captured, but flees with his friends to the Western Air Temple with Zuko trailing them on a stolen warship balloon.
