Koh: It's been a long time since I've added a child's face to my collection. So, how may I help you?
Aang: I need to find the moon and the ocean.
Koh: Their spirit names are Tui 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 round... SOMEONE'S GOING TO KILL THEM!
Aang: What do you mean? How can I find them and protect them?
Koh: You've already met them. Tui and La, the 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: (remembering the fish in the Spirit Oasis) The Koi Fish! (Koh spins back to Aang, who quickly wipes the excitement off his face) I must be going now.
Koh: We'll meet again...

Koh: My old friend, the Avatar. It's been a long time.
Aang: You...know me?
Koh: Oh, how could I ever forget you? [Changes face to that of an angry-looking man.] ONE OF YOUR PREVIOUS INCARNATIONS TRIED TO SLAY ME! It was eight or nine-hundred years ago.
Aang: I didn't know that. Why did he...or I...try to kill you?
Koh: [Changes face to that of Ummi, Avatar Kuruk's wife.] Oh, it was something about stealing the face of someone you loved. [Changes face to that of a screaming baboon in an attempt to scare Aang.] HA HA HA! [It doesn't work and Koh keeps talking, bringing his fanged maw right up behind Aang's ear. ] Of course, that's all behind us. Why should I hold a grudge against you for something in a past life? After all, you're a different person now. You've come to me... with a new face.

Lion Turtle: The true mind can weather all the lies and illusions without being lost. The true heart can tough the poison of hatred without being harmed. Since beginningless time, darkness thrives in the void, but always yields to purifying light.

Lion Turtle:In the era before the Avatar, we bent not the elements, but the energy within ourselves. To bend another's energy, your own spirit must be unbendable or you will be corrupted and destroyed.

Lo: Azula, we've heard what happened.
Li: Why have you banished all your servants?
Lo: And your Dai Li agents?
Li: And the Imperial Firebenders?
Azula: None of them could be trusted. Sooner or later they all would have betrayed me, just like Mai and Ty Lee did.
Lo & Li: Azula, we are concerned for you and your well-being.
Azula: My father asked you to come down here and talk to me, didn't he? He thinks I can't handle the responsibility of being Fire Lord. But I will be the greatest leader in Fire Nation history.
Lo: I am sure you will, but considering everything that has happened today.
Li: Perhaps it's best if we postpone your coronation.
Azula: (turns around) What?! Which one of you just said that?
(Lo and Li point at each other)
Azula: What a shame. There's only one way to settle this. You two must duel each other! I order you to fight an Agni Kai!
Lo: But...
Lo & Li: We're not Firebenders.
Azula: All right, fine. (points at Li) Lo, you're banished, (points at Lo) Li, you can stay. (walks away)
Li: But I'm Li. So who's banished?
Lo: (shrugs)

Long Feng: By the way, I'm Long Feng. I'm a cultural minister to the king.
Katara: I'm Kua Mai, and this is [gestures to Toph]...Dum.

Longshot: (speaking for the only time on-screen) There's no time. Just go. We'll take care of him. He's our leader.
Jet: Don't worry Katara, I'll be fine.
Toph: (sadly as she's walking away to Sokka) He's lying.

Mai: Orange is such an awful color.
Zuko: You're so beautiful when you hate the world.
Mai: I don't hate you.
Zuko: I don't hate you, too.

Mai: (to Azula) Please tell me you're here to kill me.

Mai: [About Omashu.] There really is no fathoming the depths of my hatred for this place.

Mai: I thought you ran off and joined the circus? You said it was your calling.
Ty Lee: Well, Azula called a little louder.

Mai: She [Azula] can shoot all the lightning she wants at me, I'm not going into that wall sludge juice. (Shudders, then closes hatch Katara, Sokka, and Ty Lee jumped into)

Mai: Wads of wet fur, how delightful.
Ty Lee: Hmm, they're not wads, they're more like, bundles. Or bunches? It's got an "uh" sound.
Mai: ...Clumps?
Ty Lee: (hugs Mai) Clumps! They're clumps!

Male Villager: (While Zuko is fighting) Give him a left! A left!
Female Villager: It's not a fist fight.
Male Villager: He's got a left sword, don't he?

Master Pakku: (holding up an amulet) Katara, I want you to have this. This amulet contains water from the Spirit Oasis. The water has unique properties. Don't lose it.
Katara: (hugs him) Thank you, Master Pakku.
Master Pakku: Aang. (gives Aang some scrolls) These scrolls will help you master waterbending. But remember, they're no substitute for a real master. (glances at Katara)
(Aang bows and steps away)
Master Pakku: Sokka...
(Sokka steps forward eagerly)
Master Pakku: (pats Sokka on the shoulder dismissively) Take care, son.
(Sokka frowns and steps back)
