Avatar: The Last Airbender, Season 3

Zuko apologizes to Iroh for his previous betrayal at Ba Sing Se

Zuko:
Uncle, I know you must have mixed feelings about seeing me. But I want you to know... I am so, so sorry, uncle. [starts crying] I am so sorry and ashamed of what I did! I don't know how I can ever make it up to you, but I...

[Iroh grabs Zuko by his shirt and pulls him close, tearfully hugging him]

Zuko:
How can you forgive me so easily?! I thought you would be furious with me!

Iroh:
I was never angry with you. I was sad, because I was afraid you'd lost your way.

Zuko:
I did lose my way.

Iroh:
But you found it again. And you did it by yourself! And I'm so happy you found your way here.

Zuko:
It wasn't that hard, uncle. You have a pretty strong scent.
