Avatar: The Last Airbender, Season 2

Iroh:
Zuko, remember that plant that I thought might be tea?

Zuko:
You didn't!

Iroh:
I did. [Iroh turns around to reveal his red, swollen face which he is scratching] And it wasn't.

Zuko:
Yah!

Iroh:
When the rash spreads to my throat, I will stop breathing. But look what I found! These are bacui berries, known to cure the poison of the white jade plant. That, or macahoni berries that cause blindness.

Zuko:
We're not taking any more chances with these plants! We need to get help.

Iroh:
But where are we going to go? We're enemies of the Earth Kingdom, and fugitives from the Fire Nation.

Zuko:
If the Earth Kingdom discovers us, they'll have us killed.

Iroh:
But if the Fire Nation discovers us, we'll be turned over to Azula.

[Both look at one another and nod]

Zuko:
Earth Kingdom it is.
