Summary of the episode
Avatar: The Last Airbender: Book 1 Water Episode 20 starts with Zuko struggles to find a place for Aang and himself. They are both stuck at tundra. At this time, Katara, Yue, and Sokka try to find them, and Fire Nation is still damaging the city.
Now in the Spirit World, Roku tries to contact Aang. He tells Aang that moon and ocean spirits went to the mortal world a long time ago. Also, Koh the Face Stealer is the only spirit who remembers this.
However, when Aang meets Koh, he should not express any emotion, or else Koh will steal his face.
Now again, in the mortal world, Zhao tells Iroh all his plans. When he was serving as Lieutenant in the Earth Kingdom, he learned that there is a secret library in the basement. Here he learns how the moon spirit looks in the mortal form.
Furthermore, Zhao thinks he has to destroy all the spirits. In the meantime, Koh tells Aang the name of the spirits name which is La and Tui (means push and pull). It also tells him that both of them are in danger.
Aang finds out Koi Fish are all the spirits and then heads back to the mortal world. Once he is back, he saw Zuko is injured and saves him.
Zhao now captured the moon spirit, and it causes a lunar eclipse. This also causes the water benders to lose control over their power. Both Iroh and Aang warn Zhao and explain that the whole world depends on the balance between ocean and moon, which includes Fire Nation.
