Jeong Jeong: Get out.
Aang: Master, I need to learn Firebending.
Jeong Jeong: Only a fool seeks his own destruction.
Aang: I'm the Avatar. It's my destiny to...
Jeong Jeong: Destiny? What would a boy know of destiny? If a fish lives it's whole life in this river, does he know the river's destiny? No! Only that it runs on and on, out of his control. He may follow where it flows, but he cannot see the end. He cannot imagine the ocean.
Aang: Okay... But it's Avatar's duty to master all of the Bending disciplines.
Jeong Jeong: To master the Bending disciplines, you must first master discipline itself. But you have no intrest in this, so I have no intrest in you! Now, get out.
Aang: Please, I have to learn. This could be my only chance.
Jeong Jeong: Are you deaf? How can I teach you if you refuse to listen? Before learning Firebending, you must learn Water and Earth. Water is cool and soothing, Earth is steady and stable. But Fire... Fire is alive. It breathes, it grows. Without the Bender, a rock will not throw itself! But Fire will spread and destroy everything in it's path if one does not have the will to control it! That is its destiny! You are not ready! You are too weak!
Avatar Roku: You think I am weak?
Jeong Jeong: Avatar Roku! No, no! I did not mean that.
Avatar Roku: I have mastered the elements a thousand of times in a thousand lifetimes. Now, I must do it once again. You *will* teach the Avatar Firebending.
Jeong Jeong: Yes, yes. I will teach you.
Aang: Really? That's great!
Jeong Jeong: Agh...
