Avatar Book 2 Earth Episode 14 - City of Walls and Secrets Episode Title:City of Walls and Secrets.Episode Description:Aang and the rest of the group arrive in Ba Sing Se, determined to find Appa and inform the Earth King about upcoming opportunity the solar eclipse will provide to strike back against the Fire Nation. However, they soon discover that the protocols and bureaucracy of the royal court and aristocracy surrounding the Earth King keep them perpetually stalled from making contact with him. They are assigned a liaison, an uncomfortably cheerful young woman named Joo Dee, who indirectly makes it clear to them that any mention of the war is forbidden within the walls of the city, one of many disturbing rules they begin to encounter that are enforced by the Dai Li, the secret police of Ba Sing Se, and their corrupt leader, Long Feng, who appears to know something about Appa. Elsewhere, Jet repeatedly tries and fails to gather evidence that Zuko and Iroh are firebenders, and his allies in the Freedom Fighters begin to believe he is losing his steel. His last attempt, challenging Zuko to a sword fight, ends in his own arrest and being brainwashed by the Dai Li into believing there is no war in the city.
