Voices from his past echo in Zuko's mind at the very end of 'The Crossroads of Destiny'…

I don't own Avatar.

That's who you are, Zuko – someone who keeps fighting even though it's hard.

No matter how things may seem to change, never forget who you are.

I care about you!

I think of you as my own.

Everything I've done, I've done to protect you.

It's time for you to choose.

I'm sorry, Uncle.

I need to find my own way.

And then WHAT? You never think these things through!

It's time for you to look inward, and start asking yourself the big questions: who are you? And what do YOU want?

I want my honour.

What that means is up to you.

Today, you restored your own honour.

Azula always lies.
