But the kids' plans change when they meet General Fong, an aggressive military man who wants to use Aang's "Avatar State" powers to end the war immediately. General Fong has a plan to get Aang into the "Avatar State" and then head into the Fire Nation to defeat the Fire Lord. Meanwhile, Zuko learns that his sister, Azula, has been sent to bring him and Uncle Iroh back to the Fire Nation to be punished as

As the kids travel through the Earth kingdom, they realize getting to Omashu is more dangerous than they thought the Fire Nation is everywhere. So when they meet a group of hippie-like nomads who tell them about a secret pass to Omashu, they decide to travel with them. The kids and nomads enter into the pass known as "The Cave of Two Lovers" (which is essentially a giant cave through the mountains) and they soon become trapped and lost in the underground labyrinth. Meanwhile, Zuko and Uncle (lying about who they really are) befriend some Earth Kingdom civilians whose lives have been hurt by the Fire Nation.

After discovering that Omashu has been taken by the Fire Nation, Aang's plan of learning Earthbending is put aside he has a new mission, to save the citizens of Omashu and his friend, King Bumi. The kids manage to sneak into the great city and get the citizens out by pretending there is a plague. But Bumi is still locked away in the city. So when Katara, Sokka and Aang return to get the king, Azula and her newest sidekicks, Mai and Ty Lee, confront them. There is an awesome fight and in the end we learn that Bumi does not need to be saved he has a plan for later

The kids crash land in a mysterious swamp, and they are separated from Appa and Momo. When they go off to look for them, they get separated themselves and end up chasing mysterious visions. The kids reunite in the middle of the swamp where they face an angry swamp monster.

When the kids hear about a town that celebrates something called "Avatar Day", they are excited to visit. But when they get there, they realize that the town is actually celebrating their hate for the Avatar. Aang finds out that the reason the town hates and fears him is because of a supposed crime he committed against the town in a former life on this very day. Aang vows to prove his innocence. Meanwhile, Zuko, now poor and on the run, uses his 'Blue Spirit' persona to steal things for him and Uncle. Uncle is not happy with what Zuko is doing and Zuko decides to go off on his own -- the two part ways.

Still looking for an Earthbending teacher for Aang, the kids come to a town where they hear about an Earthbending tournament Earth Rumble Six Aang is certain he'll find a teacher there. The Earth Rumble tournament is like our version of wrestling with a lot of extravagant, muscley Earthbenders with unusual nicknames and specialized moves. (Examples are The Hippo, the Boulderand The Gopher. They sport moves like "rocking the boat" and "burrowing".) The objective is to knock your opponent out of the ring. The kids are very impressed with all the Earthbenders but none of them seem to be right to teach Aang. Until the final Earthbender comes out. She is a small blind girl and the champion of the tournament, nicknamed "The Blind Bandit." Aang is certain she is the right girl but when he goes up to talk to her, he ends up having to fight her!

Zuko, who is now on his own (no longer traveling with Uncle Iroh) is worn-out and hungry as he travels on his ostrich-horse through the Earth Kingdom. Considered and enemy to the Earth Kingdom and a traitor to the Fire Nation, Zuko is not welcome anywhere. He comes to a small Earth Kingdom town where bully Earth Nation soldiers are keeping the town in fear. Zuko stands his ground when faced with the menacing Earthbenders and helps to keep a young boy, Lee, out of trouble. Lee takes Zuko to his meet his family. Zuko is welcomed to stay and he ends up helping Lee's father around their farm. When the Earth Nation soldier thugs come to the farm to cause trouble, Zuko again stands his ground against them. Zuko has flashbacks of the last times he saw his mother and to the rise of his father as Fire Lord.

The kids (now including Toph) are chased by a relentless and mysterious tank-train. Several times the kids land and set up camp just to see that the tank train is coming right for them again they quickly get on Appa and leave. After this happens a few times, the kids finally decide to face whoever is in the tank-train. But when they realize that it is Azula, Mai and Ty Lee they decide the best thing to do is keep running.

This is the first episode with the Mongoose Dragons. These are large animals that Azula, Mai and Ty Lee ride on. They are a cross between a Mongoose and a basilisk, a lizard that can run across water. While they travel on land they are on all fours but they are also able to stand on their hind legs and sprint across water.

For Aang's first Earthbending lesson the kids come to a large, natural rock quarry. Aang is excited to start Earthbending but his first attempt to bend a rock results in him being thrown back and the rock not moving. Toph tells Aang that his is not connected to the ground enough. The element Earth is the opposite of Air and therefore Aang has a tough time being grounded being "Rock-like".

Looking for information to defeat the Fire Nation, the kids meet an archeologist, Professor Zei, who knows of a secret library with an endless amount of information. The only problem is that library is hidden somewhere in the middle of the desert and Professor Zei has never actually been there. But the kids decide that with Professor Zei's knowledge and Appa as a means to get in and out of the desert, they can find the library. After a long search the kids finally find the library, buried, sinking into the desert. The kids enter except for Toph who decides to wait on the surface with Appa.

Now trapped in the desert, the kids try to make it out on foot, heading towards Ba Sing Se (the capitol of the Earth Nation). Aang is upset at losing Appa and flies on his glider looking for him, but it is no use Appa is gone. The group is running out of water so Sokka and Momo drink some cactus juice which only makes them hallucinate. Katara tries her best to keep everyone together, but it's a tough job considering Aang is upset, Toph can't really "see" in the sand and Sokka and Momo are loopy.

Zuko and Uncle decide that they need to go somewhere where Azula can't find them they decide to go to Ba Sing Se. But in order to get there they need passports and Uncle knows just where to get them. We learn for the first time that Uncle is in a Secret Society that spans across all Nations it's called the Order of the White Lotus.

Still traveling without Appa, the kids are anxious to get to Ba Sing Se to tell the Earth King about their plan to attack the Fire Nation and, more importantly, to find Appa. But getting to Ba Sing Se is harder than they thought. The kids pass up taking the easy way to Ba Sing Se (a peaceful ferry ride across a lake) and instead vow to help a desperate family of refugees that are unable to take the ferry. The kids lead the family to Ba Sing Se the only other way they know, through the deadly Serpent's Pass.

Having made it on top of the outer wall of Ba Sing Se, the kids see a frightening sight a Fire Nation army is heading right towards them, and leading the army is a giant, mobile drill. The drill is several stories high and moving like a caterpillar it is just a matter of time before it reaches the wall and drills through it putting all of Ba Sing Se in danger. The kids find an Earth Kingdom army who is trying to stop the giant drill but it is no use it seems unstoppable.

While still on the ferry, Jet asks Zuko if he wants to join his group of freedom fighters. Zuko turns down Jet's offer and Jet become suspicious of Zuko and Uncle he suspects they are Fire Nation. When they all make it into Ba Sing Se, Jet and his gang follow Zuko and Uncle

Having finally made it into Ba Sing Se, the kids are given a house in the upper ring an upper class area of the city. The kids are anxious to tell the Earth King their plan but they find out they won't be able to speak to the king for a month. The kids decide that they can't wait a month and so they break into a private party that the Earth King is throwing they figure they can talk to the king here.

Meanwhile, Jet and his small gang follow Uncle and Zuko, trying to prove that they are Firebenders. When Uncle and Zuko get jobs at a teahouse, Jet continues to spy on them. But when Jet can't get the proof he needs, he decides to fight Zuko -- certain that Zuko will have to use his Firebending to defend himself.

Appa is taken by the Sandbenders from the library and sold to the Bedouins. Although Appa is tied down, he is hard to control so the Bedouins sell Appa to a traveling Fire Nation circus. At the circus, a cruel animal trainer "breaks" Appa and forces him to perform in the circus. Appa manages to break free from the circus and goes searching for Aang. Unable to find him, he looks for a place to rest. Appa finds shelter in a barn, but he is violently chased away by a farmer. Still looking for shelter, Appa finds a cave but realizes that the cave is home to another animal a Boar-q-pine. The two animals have a vicious fight and Appa is injured, stuck with Boar-q-needles. Appa is now becoming more animalistic and it shows when Suki (from Book 1 Chapter 4) comes across him. Appa is like an angry beast and Suki has to calm him down. She and the other Kyoshi warriors take care of Appa but it doesn't last for long the Kyoshi warriors are attacked by Azula, Mai and Ty Lee -- and Appa is forced to flee.
