Sokka:
Pretty clouds.

Zuko:
Yeah.. fluffy. [Sokka begins to whistle due to awkward silence]

Zuko:
What?

Sokka:
Wha-- Oh! I didn't say anything. [Brief silence]

Sokka:
You know, a friend of mine designed these war balloons.

Zuko:
No kidding.

Sokka:
Yep! A balloon... but for war.

Zuko:
There's one thing my dad's good at, it's war.

Sokka:
Yeah, it seems to run in the family.

Zuko:
Hey. Hold on, not everyone in my family is like that.

Sokka:
I know. I know, you've changed.

Zuko:
I meant my Uncle... He was more than a father to me... And I really let him down.

Sokka:
I think your uncle would be proud of you. Leaving your home to come help us. That's hard.

Zuko:
It wasn't that hard.

Sokka:
Really? You didn't leave anyone behind you care about?

Zuko:
Well, I did have a girlfriend. Mai.

Sokka:
That gloomy girl who sighs a lot?

Zuko:
Yeah. [smiles] Everyone in the Fire Nation thinks I'm a traitor. I couldn't drag her into it.

Sokka:
My first girlfriend turned into the moon. [frowns]

Zuko:
That's rough, buddy.
