3. The Earth Queen

Complete story — includes the ending

Team Avatar arrive in Ba Sing Se as part of their search for new airbenders, and receive an ambivalent welcome from Queen Hou-Ting, who is of the belief that Avatar Aang manipulated her father in his time on the throne. Korra reluctantly agrees to a tax collection effort on the Queen's behalf in order to gain her cooperation, fighting off bandits with Asami during the mission. The queen nevertheless continues to claim that there are no airbenders in the city. Meanwhile, Kai absconds from the group to pickpocket, and while looking for him, Mako and Bolin meet the family of their late father. They learn that the city's secret police, the Dai Li (who are now more firmly under the control of the throne, but are still sinister in nature) are capturing new airbenders, and indeed Kai is arrested and forced to serve in the army. At the North Pole, Zuko, the new northern water tribe chiefs Desna and Eska, and Korra's father Tonraq visit Zaheer's last imprisoned comrade, his girlfriend P'Li, a dangerous firebender.
