Sozin's Comet is only three days away. Zuko tells the others what the Fire Lord plans on the day of the comet and the gang realizes that they must stop him before then. But Aang doubts that he can do what is expected of him.
Did You Know?
What's wrong with you? You could've hurt Aang!
What's wrong with me? What's wrong with all of you? How can you sit around having beach parties when Sozin's Comet is only three days away?... Why are you all looking at me like I'm crazy?
About Sozin's Comet... I was actually going to wait to fight the Fire Lord until after it came.
I'm not ready. I need more time to master firebending.
And frankly, your earthbending could still use some work.
