After enduring the group’s gossip, he joined them to hear about Aang’s return and asked him to demonstrate his mastery of the Avatar State.

• After everyone agreed to stop discussing Kahn’s love life for the time being, Sokka questioned whether Aang had truly mastered the Avatar State.
• Aang admitted that Kahn had advised him about spiritbending, and Kahn urged him to demonstrate his mastery.

Aang demonstrated his fully mastered Avatar State, leaving Kahn shaken by its overwhelming power and wondering why he feared facing Aang. After Toph returned from a failed attempt to reconcile with her parents, Team Avatar decided to take a short trip, and Kahn suggested a destination.

• Aang entered the Avatar State, and Kahn and the others witnessed the immense power and control he had gained.

• Toph returned after arguing with her parents, who had tried to keep her at home, and happily reunited with Team Avatar.
• With a week remaining before the operation, Team Avatar chose to take a short trip, and Kahn said he had somewhere he wanted to go.

Team Avatar visited Jade Island, where Kahn explained that the Fire Nation colony could help Aang and Zuko consider how to restore balance after defeating Ozai. The group saw its prosperity and tensions between Fire Nation and Earth Kingdom residents, and the chapter left them facing the colonies as a major problem.

• Aang asked Kahn why he had chosen Jade Island, and Kahn said an old friend had once invited him to visit.
• Zuko realized Kahn wanted him and Aang to consider how to handle the colonies, which Kahn identified as a major challenge after Ozai’s defeat.

Kahn challenged Aang, Zuko, Sokka, and Toph to consider the complications of returning the Colonies to the Earth Kingdom, especially the residents who had built lives and families there. He left Zuko with a harsh answer: if Zuko remained committed to his ideals, he should suppress opposition and carry out his plan anyway.

• Aang and Zuko agreed that the Colonies should be returned to the Earth Kingdom, while Sokka proposed sending Fire Nation residents home.
• Kahn explained that people from the Fire Nation and Earth Kingdom had formed families in the Colonies, making simple ethnic divisions impossible.
• Aang and Katara voiced support for people of different nations being together, and Zuko said residents should be allowed to leave with him if they wished.

• Kahn told Zuko to dismiss, imprison, and publicly behead an opponent if that was necessary to continue carrying out his ideals.

Kahn explained how powerful people could falsely claim to speak for ordinary citizens and use history to excuse Fire Nation aggression. As Zuko considered asking Iroh for political guidance and then asked Kahn to teach him, Kahn recalled Azula’s offer to govern the Fire Nation together and suddenly froze.

• Kahn challenged Aang and the others to recognize that the speaker in his story represented privileged people, not the war’s ordinary victims.
• Kahn explained that the speaker’s references to distant history and cities built by the Fire Nation were attempts to deny and justify colonization.
• Zuko resolved to learn from Uncle Iroh, but Kahn warned him that Iroh was not suited to teach politics.
• Zuko asked Kahn to teach him, but Kahn refused, calling himself an armchair strategist.
• Katara questioned whether executing the speaker would be excessive, and Kahn said it could deter others from causing trouble.
• Kahn remembered Azula asking him to govern the Fire Nation with her, then suddenly froze as he considered her ambitions.

At the beach resort, Kahn meditated on his feelings for Azula and realized his central conflict was whether he could give up his freedom to govern the Fire Nation with her. He decided to return and speak with her, then was asked to weigh in on the group's debate over Ozai's fate.

• Kahn reflected on Azula's proposal to govern the Fire Nation together and recognized that he feared being confined by politics and losing his freedom.
• Kahn considered whether he and Azula could compromise, but admitted he did not know and decided to return to speak with her in person.
• Kahn left his meditation and found Aang, Zuko, and Sokka debating whether Ozai should be killed.
• Aang asked Kahn what he thought, and Kahn told him to do what he believed was right while privately intending to claim Ozai's head himself.

Aang remained conflicted about whether to kill Ozai after Kahn outlined the dangers of both choices, while Team Avatar enjoyed the end of their vacation. At Chameleon Bay, they learned Iroh had begun the counteroffensive and liberated Omashu, as Team Avatar prepared to carry out the next phase of the plan.

• Kahn described how leaving Ozai alive could lead to Zuko's assassination and another war, while he also warned that killing Ozai might provoke terrorist attacks.

• Katara and Sokka reunited with their father, Hakoda, and Sokka asked whether he had found the people they needed.

Hakoda gathered forces from the Northern Water Tribe and the Earth Kingdom for an assault on the Fire Nation capital, while Tezin arrived with Sokka’s secret weapons. The chapter ended with Kahn discovering that one of those weapons was a submarine.

• Tezin and Teo arrived aboard Hakoda’s ship after a peanut butter bomb experiment exploded, and Aang introduced them to Kahn, Toph, and Zuko.
• Kahn learned that Li Ming had forced Tezin to invent weapons and taken credit for his work, and he resolved to tell Azula to fire Li Ming.

• Sokka took Tezin and the others to see the secret weapons they had prepared, and Kahn discovered a submarine.

Kahn and the others inspected Sokka and Tezin’s improvised weapons before Hakoda accepted command of the allied forces. Hakoda outlined their plan to reach the Fire Nation capital during the solar eclipse and escort Team Avatar to the Royal Palace for the final battle.

• Tezin showed Kahn and the others a waterbender-powered submarine, ice-encased torpedo bombs, and heavy landing tanks that Sokka had helped design.

• Hakoda outlined the plan to breach the Gates of Azulon, land, and escort Team Avatar—including Ty Lee and Mai—to the Royal Palace before the eclipse.
• Kahn felt the final battle beginning as Sokka prepared to explain the weapons and vehicles.

Hakoda's fleet used Waterbenders' fog and torpedoes to sink a Fire Nation warship and intercept its messenger hawk. As the fleet continued its voyage toward Azulon Bay, Aang remained troubled over what to do about Ozai, while Katara suspected Kahn was hiding something.

• Kahn spotted a Fire Nation fleet ahead, and Hakoda ordered the Waterbenders to cloak their ships in fog so they could pass unseen.
• Kahn detected a Fire Nation warship directly in their path, and Hakoda ordered the fleet to prepare torpedoes while Aang blocked the enemy's airspace.
• The Waterbenders launched ten torpedoes that tore holes in the warship, and the Earthbenders blocked its return shot as it sank.
• Aang intercepted the messenger hawk, destroyed the message, and returned with the bird after the fleet defeated the warship.
• Sokka and Zuko argued over what to do with the hawk, while Katara worried about Aang's indecision over Ozai and wondered what Kahn was hiding.

The invasion force passed Azulon’s Gate underwater and surfaced near the Fire Nation capital, where Kahn challenged Aang’s belief that only the Avatar should decide Ozai’s fate. Kahn then flew toward the Royal Palace, leaving Aang and Katara alarmed and urging him to hurry after.

• Hakoda ordered the force to rest before beginning the next stage of the operation, and Katara suggested Aang defeat Ozai and imprison him rather than decide immediately whether to kill him.
• The vessels reached Azulon’s Gate, and Hakoda ordered everyone to abandon ship and board the submarines when the Fire Nation raised its fiery barrier.
• The force passed beneath the gate, and Toph became seasick aboard the submarine before the group surfaced to replenish its air.
• Zuko and Mai reunited near the capital, while Aang and Katara appeared to have grown closer.
• Kahn told Aang that the world did not depend on the Avatar alone to resolve its problems and that others had a say in Ozai’s fate.
• Kahn flew toward the Royal Palace on Wu, and Katara urged Aang to hurry after him.

• Kahn absorbed the guards’ fire and unleashed a blast that incapacitated them, leaving only Woolf able to rise.
• Ozai attacked Kahn with lightning, but Kahn redirected it back toward him.
• A stone pillar blocked Kahn’s redirected lightning, and Aang arrived and told Kahn to stop.

Kahn pursued his obsession with killing Ozai, while Aang tried to stop him and keep Ozai from escaping. After Kahn’s lightbending severed Ozai’s legs, the solar eclipse left Kahn unable to bend; he used Mai’s knife-throwing to kill Ozai and left Aang stunned.

• Aang confronted Kahn over his determination to kill Ozai, and Kahn admitted he wanted Ozai to die by his own hand.

• As Aang left the Avatar State, Kahn threw a knife into Ozai’s forehead and killed him.

After the war ended, Kahn explained to Team Avatar why he had killed Ozai and how his long conflict with Ozai had unfolded. He acknowledged his stubbornness but said he would make the same choice again, then announced that it was time for him to go back.

• Kahn told Team Avatar what had happened in the palace, prompting the group to discuss why Aang had opposed killing Ozai.
• Kahn explained that Aang might fear relying on killing as an easy way to solve problems, though he did not know why Aang had tried to stop him specifically.
• Kahn recounted his history with Ozai, including his bond with Iroh, his efforts to find Ershu, and the schemes that forced him to feign obedience.
