I don't know what they did to you. I don't know what's different in your life. If you're the same Katara who brought me back to life when I actually died at Ba Sing Se. Or if you're the same Katara who danced with me in a Fire Nation cave. Or the one who solved the riddle of the Cave of Two Lovers with a kiss. But I know... I know that no matter how much they changed you, you still started off as the same Katara.

You're the daughter of Kya and Hakoda, right? The last Waterbender of the Southern Water Tribe? The brother of Sokka, who loves meat and sarcasm? The girl who woke up the Avatar and without whom the world wouldn't be saved? The girl who... [he chokes on his words a second] went penguin sledding with me? Katara is Katara, no matter what. I know this is hard for you, but... you'll still be Katara tomorrow. The Katara I kn- love.

[He meekly trails the last word out.]
