Synopsis
The episode starts with Team Avatar convincing June to use her Shirshu, Nyla, to track Aang using his staff. Unfortunately, the Shirshu can’t track him because he is "gone" or in other words, doesn’t exist. Aang finds himself wondering where he is and knows he’s not in the Spirit World because he can bend. Zuko has another idea to save the world and brings back Iroh's rancid sandals as a smell sample for Nyla to track. Nyla runs off to find the source and the Gaang follows on Appa, which eventually leads them to Ba Sing Se after a day-long journey. They decide to camp out at the outer walls of Ba Sing Se.

Aang soon finds a weird hexagon symbol on the ground and feels that it’s not normal earth. Lost for thoughts, Aang decides to contact his past lives for wisdoms on what to do now that Aang has to kill the Fire Lord. Even Avatar Roku doesn't know where they are, but the past four Avatars suggest to Aang to kill Fire Lord Ozai, even Avatar Yangchen, a fellow Air Nomad.

Meanwhile, the group is woken up by a fire, started by Jeong Jeong and they meet Piandao, Pakku (who has become Katara's and Sokka's grandfather), and Bumi. They reveal that they are members of the Order of the White Lotus, who came together after called by Iroh, the Grand Lotus. Bumi sees that someone is missing, but only asks where Momo is. Sokka answers he is with Aang and they are missing. Bumi says, without a single worry, that Aang will be alright if he is with Momo. Bumi revealed that he stopped the Fire Nation that took over Omashu during the eclipse. Because the firebenders were powerless, Bumi easily defeats the entire Fire Nation singlehandedly force and gets Omashu back for himself.

Zuko is worried that Iroh will be mad at him after all he has done. Katara comforts him and Zuko enters the tent Iroh is in and before he starts to apologize, he sees that Iroh is asleep. The next morning, Iroh wakes up to find Zuko waiting for him. Zuko apologizes for all he has done, but before he asks what he can do to make it up for Iroh, the latter hugs his nephew, much to Zuko’s surprise. Iroh states he wasn’t angry at Zuko, but was afraid he lost his way. Zuko says he did lose his way, but Iroh assures him he found his way once more.

Aang sees mountains becoming closer and realizes that the island is swimming. He swims underneath the water and sees a giant arm paddling. He goes to meet the head of the one swimming towards land.

Zuko asks for Iroh to stop the Fire Lord, but Iroh says he can't do it because if he does kill the Fire Lord (a brother killing a brother) it will be a senseless way to end the war and that the Avatar must do so. He also states that after Ozai is defeated, Zuko must take the throne. Soon, Iroh tells Zuko that he must stop Azula to take the throne, but Zuko also brings Katara to help as well. While they do that, Sokka, Suki, and Toph will stop the air fleets. They must ride on an Eel-Hound to get to the air fleets and stop them all. Iroh says that after the reconquer Ba Sing Se, Iroh will reopen his tea shop, the Jasmine Dragon.

Aang finds that the thing swimming is a Lion Turtle. He asks for wisdom on how to stop the Fire Lord without taking his life. The Lion-Turtle answers, "The true mind can weather all lies and illusions without being lost. The true heart can touch the poison of hatred without being harmed. From beginningless time, darkness thrives in the void, but always yields to purifying light". The Lion-Turtle brings up a paw, his two claws touching Aang's chest and forehead, causing a green light to illuminate. Aang doesn’t understand, but is comforted by this wisdom. He is let on land and waits for the arrival of the Phoenix King. The next morning, the air fleets of the Fire Nation, led by Ozai, starts while Aang waits. Sozin's Comet can be seen arriving the Earth.
