Heres my idea of the final battle:
Katara: look, aang, I know that you dont need me to control the avatar state, so i must do what i have to do!(she jumps in front of the fire lords attack)
Aang:nnnnnnnnnnooooooooooooooooooooooooooooo!!!!!!
(katara falls to the ground. aang walks up to her to feel her pulse.)
Aang
(quietly with increasing noise every sentence) no pulse. she's dead. she's dead. (he goes into the avatar state)
To be continued... (i will tell you the ending after 10 replies)
