--> "Who are ''you'' and what do ''you'' want?"
The Gaang continues their search for Appa in Ba Sing Se. While setting up posters, Katara comes across an old friend: Jet. Jet claims to have seen Appa and the Gaang begrudgingly accepts his help. Unfortunately, Jet has been brainwashed by Dai Li agents and is leading the Gaang on a false trail.
Meanwhile, Iroh's tea-making finally pays off, as he is given his own tea shop in the Upper Ring. Zuko continues his search for Aang upon realizing that he is in the city looking for Appa. Iroh confronts Zuko and tries to help him understand that he decides his own destiny and not the people around him.

* CurbStompBattle: The Gaang vs. the Dai Li. Toph alone takes down over half of them.
* CutApart: Team Avatar opens the door to where they think Appa is, and Appa looks up at the opening door to see... Zuko. A mild lampshading follows as Zuko snarks, "Expecting someone else?"
* ElaborateUndergroundBase: The base the Dai Li have beneath Lake Laogai.

* ShoutOut: Iroh tells Zuko he needs to ask himself the "big questions": [[Series/BabylonFive "Who are you?" and "What do you want?"]]
* TerribleArtist: Sokka's attempt to make the lost offer poster for Appa is rather... bad, to say the least. It's made even better by this exchange:
-->'''Toph:''' [[BlatantLies It looks just like him to me!]]

* TriggerPhrase: The sentence "The Earth King has invited you to Lake Laogai" activates the brainwashing.
