Avatar: The Last Airbender, Season 3

Zuko:
After I leave here today, I'm going to free Uncle Iroh from his prison, and I'm going to beg for his forgiveness. He's the one who's been a real father to me.

Ozai:
[Laughs] That's just beautiful. Maybe he can pass down to you the ways of tea and failure.

Zuko:
But I've come to an even more important decision. I'm gonna join the Avatar, and I'm going to help him defeat you.

Ozai:
Really? Since you're a full blown traitor and you want me gone, why wait? I'm powerless. You've got your swords. Why don't you just do it now?

Zuko:
Because I know my own destiny. Taking you down is the Avatar's destiny. Goodbye.

Ozai:
Coward! You may think that you're brave enough to face me, but you'll only do it during the Eclipse. If you have any real courage, you'll stick around until the sun comes out. Don't you want to hear what happened to your mother?
