Avatar: The Last Airbender, Book 3: Fire

Toph:
Geez, everyone is getting so upset about their characters. Even you seem more down than usual. And that's saying something.

Zuko:
You don't get it. It's different for you. You get a muscly version of yourself taking down ten bad guys at once and making sassy remarks.

Toph:
Yeah, that's pretty great.

Zuko:
But for me, it takes all the mistakes I have made in my life and shoves them back in my face. My uncle. He's always been on my side even when thing were bad. He was there for me. He taught me so much. And how do I repay him? With a knife in his back. It's my greatest regret and I may never get to redeem myself.

Toph:
You have redeemed yourself to your uncle. You don't realize it, but you already have.

Zuko:
How do you know?

Toph:
Beacause I once had a long conversation with the guy. And all he would talk about was you.

Zuko:
Really?

Toph:
Yeah, and it was kind of annoying.

Zuko:
Oh, sorry.

Toph:
But it was also very sweet. All your uncle wanted was for you to follow your own path and see the light. Now you're here with us. He'd be proud. (Toph punches him on the shoulder)

Zuko:
Ow! What was that for?!

Toph:
That's how I show affection.
