Uncle Iroh: [to Zhao] The Fire Nation needs the moon, too. We all depend on the balance. Whatever you do to that spirit, I'll unleash on you tenfold! Let it go, now!
Master Pakku: Nice try, Pupil Sangok. A couple of more years and you might be ready to fight a sea sponge. Would anyone care for a rematch with Katara?
[the class groans]
Master Pakku: Katara, you've advanced more quickly than any student I've ever trained. You have proven that with fierce determination, passion and hard work, you can accomplish anything. Raw talent alone is not enough.
Admiral Zhao: It's my destiny to destroy the moon and the Water Tribe.
Aang: Destroying the moon won't hurt *just* the Water Tribe. It will hurt everyone, including you. Without the moon, everything would fall out of balance. You have no idea what kind of chaos that would unleash on the world.
Admiral Zhao: I was a young Lieutenant serving under General Shoo in the Earth Kingdom. I discovered a hidden library, underground, in fact. I tore through scroll after scroll. One of them contained a detailed illustration and the words moon and ocean. I knew then that these spirits could be found and killed. And that it was my destiny to do so.
Uncle Iroh: Zhao, the spirits are not to be trifled with.
Admiral Zhao: Yes, yes, I know you fear the spirits, Iroh. I've heard rumors about your journey into the Spirit World. But the ocean and moon spirits gave up their immortality to become a part of *our* world. And, Now they will face the consequences.
Koh: Their spirit names are Twee and La. Push and Pull. And that has been the nature of their relationship for all time.
Aang: Please, help me find them. An entire culture could be destroyed if I don't get their help.
Koh: Oh, you think you need their help? Actually, it's quite the other way around.
Aang: [about the Ocean and Moon] How can I find them and protect them?
Koh: You've already met them, actually. Twee and La, your Moon and Ocean, have always circled each other in an eternal dance. They balance each other. Push and pull. Life and death. Good and evil. Yin and Yang.
Aang: [Suddenly understanding with a burst insight, allowing his face to show emotion while Koh is looking away] The koi fish.
[Hearing the emotion in his voice, Koh quickly turns to steal Aang's face; but no luck, Aang becomes unemotional once more as Koh turns]
Uncle Iroh: It's almost twilight, Admiral. As your military consultant, I must advise you to halt your attack. The Waterbenders draw their power from the moon, and it is nearly full tonight. You should wait and resume the attack at daybreak.
Admiral Zhao: Oh, I'm well aware of the moon problem. And I am working on a solution. But for now, daybreak it is.
Admiral Zhao: I am... a legend now. The Fire Nation will, for generations, tell stories about the great Zhao who darkened the moon. They will call me Zhao the Conqueror. Zhao the Moonslayer! Zhao the Invincible!
[At this moment Momo jumps onto Zhao's head and starts pulling at his face and chittering]
Katara: He's crossing into the Spirit World. He'll be fine as long as we don't move his body. That's his way back to the physical world.
Princess Yue: [Telling the story of her birth] When I was born, I was very sick and very weak. Most babies cry when they are born, but I was born as if I were asleep, my eyes closed. Our healers did everything they could. They told my mother and father I was going to die. My father pleaded with the spirits to save me. That night, beneath the full moon, he brought me to the oasis and placed me in the pond. My dark hair turned white. I opened my eyes and began to cry, and they knew I would live. That's why my mother named me Yue, for the moon.
Sokka: You did everything you could. And now we need to do everything we can to get him back. Zuko can't have gotten far. We'll find him. Aang's going to be fine.
