Well, shit, turns out Ba Sing Se is secretly under the control of the city's security forces, the Dai Li, and the Earth King has no fucking idea that there's even been a war going on for a century. Team Avatar manage to expose the Dai Li and convince the Earth King to pitch into the war effort. They also reunite with Appa, which the Dai Li had captured and hidden to maintain their story. The Team briefly split up to tend to their individual matters, during which Toph is captured by her parents' mercenaries. She goes "fuck that, I'm inventing a new form of earthbending, see ya losers" and learns how to metalbend. Meanwhile, Zuko and Iroh also arrive in Ba Sing Se to start a new life, and Zuko is FINALLY learning to actually be happy with himself.
Azula has other plans. Pretending to be Earth warriors, her trio infiltrate the city and release the Dai Li from prison, who then pledge their allegiance to her. With their help, she stages a coup and lures both Zuko and the Avatar to her. To the utter devastation of Iroh, Azula manages to convince Zuko to switch sides back to evil and help her fight Aang. Aang goes into the Avatar State during the battle, when Azula immediately shoots lighting through him, killing him. The good guys get the fuck out of there, and Katara is able to revive Aang with the magic water she's been carrying around from the north pole fish pond. Iroh is imprisoned, and the Earth Kingdom is finally conquered.
