Sozin's Comet: The Final Battle
Aang suddenly abandons his Firebending lesson with Zuko to have a beach party with his friends, causing Zuko to attack him in his frustration. Aang explains he plans to challenge Fire Lord Ozai only after Sozin's Comet and its enhancement of Firebending have come and gone, due to his own self-perceived lack of Firebending skills at the moment. When Zuko tells the group Ozai plans to use the comet's power to burn down the Earth Kingdom, Aang resolves to face him before the comet arrives. The entire group advises Aang to kill Ozai, but Aang refuses to kill him due to his pacifistic nature and non-violent upbringing.
