Thanks to the "mercy" of Fire Nation Emperor Ozai, the order of banishment had not been carried out immediately, leaving Zuko a few days to recover and prepare.
After the first day, everyone's emotions settled down. Now that the wood had already been made into a boat, planning for the future mattered more.
Once reason returned, Iroh remembered that he did not actually have to make the difficult choice between Zuko and Kahn. He could simply take Kahn along too.
But Kahn still chose to stay. Although the three of them staying together sounded nice, even a little analysis made it clear that this was not a good choice. It would be no different from putting all their eggs in one basket.
Remaining in the Fire Nation, though somewhat dangerous, also gave him room to maneuver.
At the same time, Azula still needed his help, and not just with the Yin Shu incident. If he were gone too, he worried that Azula might fall under Ozai's psychological control again.
Besides, he had seen everything Ozai had done over the years, especially during this incident. He had no intention of simply letting it go!
Meanwhile, although Zuko had been banished, that did not mean he could act freely, because he still had a mission: to find the Avatar.
Anyone knew how absurd that mission was, because the Avatar had not appeared in nearly a hundred years.
Kahn asked Iroh:
"Uncle Iroh, do you think the Avatar is still alive?"
"Perhaps. The Avatar's disappearance was very strange, after all. No one can be certain that he truly vanished forever."
Iroh told Kahn that although the Fire Nation had used the power of Sozin's Comet to wipe out the Air Nomads a hundred years ago, they had not found the Avatar among them.
