Avatar: The Last Airbender, Book 3: Fire

Aang (to the Painted Lady):
I'm the Avatar! (he jumps down in front of her)

Katara:
(mysterious voice): Well, hello, Avatar. I wish I could talk, but I am very busy.

Aang:
Yeah, me too; I hate that. (he looks at the Painted Lady, Katara tries to hide her face with her hat) You know, you're real pretty for a spirit. I don't get to meet many spirits. But the ones I do meet? Not very attractive. (Katara chuckles nervously)

Katara:
Thank you, but-

Aang:
You seem familiar. (he looks at the Painted Lady again, but Katara still hides her face with her hat)

Katara:
A lot of people say that.

Aang:
No. You really seem familiar.

Katara:
Look, I really should get going. (Aang Airbends her hat off, Katara grabs it, and turns away)

Aang:
Katara?

Katara (turning to face Aang; regretfully):
Hi, Aang.

Aang (points at Katara):
You're the Painted Lady?! But how?

Katara:
I wasn't at first. But since that's who everybody thought I was, I guess I kinda became her. (she drops her hat)
