Avatar: The Last Airbender, Season 3

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]
