Avatar: The Last Airbender, Season 1

[Katara, Aang and Yue gaze upon the full moon at night]

Yue:
The legends say the moon was the first waterbender. Our ancestors saw how it pushed and pulled the tides, and learned how to do it themselves.

Katara:
I've always noticed my waterbending is stronger at night.

Yue:
Our strength comes from the spirit of the moon, our life comes from the spirit of the ocean. They work together to keep balance. [Aang begins to brighten up]

Aang:
The spirits... Maybe I can find them and get their help!

Yue:
How can you do that?

Katara:
The Avatar is the bridge between our world and the spirit world. Aang can talk to them!

Yue:
Maybe they'll give you the wisdom to win this battle.

Aang:
Or maybe they'll unleash a crazy amazing spirit attack on the Fire Nation! [he looks at both Yue and Katara] Or wisdom. That's good, too.
