Katara

"You've been hallucinating on cactus juice all day, and now you lick something you find stuck to the wall of a cave?"

"Stealing is wrong... unless it's from pirates"

"Love is brightness in the dark"

"But I believe Aang can save the world"

"You can't knock me down!"

(As it starts raining) "That proves it." ("No, it doesn't. You can't really tell the future.") "I guess you're not really getting wet then."

"Monk Gyatso and the other Airbenders may be gone, but you still have a family. Sokka and I, we're your family now."

("Don't answer to Twinkle Toes, it's not manly!") "You're the one who's bag matches his belt."

"No! I will never, ever turn my back on people who need me!"
