Piandao quotes from Avatar: The Last Airbender

Don't think of your sword as a weapon. Think of it as another part of your body.

Sokka

Like a second head?

More like an extra-long, really sharp arm.

Sokka

I'm not from the Fire Nation. I'm from the southern Water tribe. I lied so I can learn swordsmanship from you. I'm sorry.

I'm sorry too.

(after their duel) Excellent work, Sokka. I think I'm a little old to be fighting the Avatar.

Aang

(shocked) How did you know?

Oh, I've been around a while. You pick things up. Of course I knew from the beginning that Sokka was Water Tribe... You might want to think of a better Fire Nation cover name. Try Lee. There's a million Lees.

Katara

But why would you agree to train someone from the Water Tribe?

The way of the sword doesn't belong to any one nation. Knowledge of the arts belongs to us all.

Suki

But wait! How do you all know each other?

All old people know each other, don't you know that?

We're all part of the same ancient secret society, a group that transcends the divisions of the Four Nations.

Zuko

The Order of the White Lotus.

That's the one!
