Doc, Sokka and others in “Chapter 3: The Painted Lady”

You know, you're (Katara) not so bad for a Waterbender.

Yeah, you wouldn't mind keeping that a secret, would you?

No problem. Keeping my mouth shut is a speciality. But my brother, Xu on the other hand, oh, he's a blabbermouth! (Sokka slaps himself in the head)

So, Doc, you ready to clean this river?

No, ma'am. I'm gonna get my other brother, Bushi. He loves cleaning rivers! (takes off his first hat and reveals another hat beneath) All right, I'm Bushi! Let's get to some river cleaning!
