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 can not see the end . He can not 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 ...
