Ozai: I am proud of you, Prince Zuko. I am proud because your sister conquered Ba Sing Se. I am proud because, when your loyalty was tested by your treacherous uncle, you did the right thing, and captured the traitor. And I am proudest of all of your most legendary acco mplishment. You slayed the Avatar.
Zuko: What did you hear?
Ozai: Azula told me everything. She said she was amazed and impressed with your power and ferocity at the moment of truth.
