Toph

("You're doing great. Just follow the sound of my voice.") "It's hard to ignore."

("The Serpents Pass? Only the truly desperate take that deadly route.") "Deadly route? Great pick, Sokka." {"Well, we are desperate"}

("Suki, are you okay? You have to be more careful. Come on!") "Thanks for saving my life, Toph. Hey, no problem Sokka."

"So you want to go see the baby, or are you going to faint like an old lady again?"

("It's so dark down here. I can't see anything.") "Oh no. What a nightmare."

"Well it sounds like a sheet of paper, but I guess you're referring to what's on the sheet of paper?"

"That's a great idea! Let the blind girl steer the giant airship."

"Oh, sorry, didn't mean to offend you, Phoenix King of getting his butt whooped." 

"Do you really think friendships can last more than one lifetime?"

"I am not Toph! I am Melon Lord!"

"There it is! That's what it will sound like when one of you spots it."

"Oh Sokka, you saved me!" ("Actually, it's me.") "Oh... well... you can go ahead and let me drown now."
