Katara: You said you're afraid of losing us, and that's why we can't stay by your side, but it's my decision to fight, not Pakku's and not yours.

Sokka: Yeah. Do you think we came here just to leave you on your own? Silly Avatar.

Aang: I don't know if I can protect you.

Katara: You can't.

Sokka: Yeah, and worrying about who will or won't get hurt, it's not just the Avatar who has to deal with that.

Katara: That's what it means to be a family.

Aang: Kuruk, Roku, Kyoshi. They all said that I need to do this by myself. The Avatar must bear the burden alone.

Katara: This is the past. Now, only one person can tell you the future. The person who'll write The Legend of Aang.

Sokka: She means you. You got that, right?
