(As Sokka and Katara try to catch up with Zuko's ship on Appa)
Sokka: Go. Fly. Soar.
Katara: Please, Appa. We need your help. Aang needs your help.
Sokka: Up. Ascend. Elevate.
Katara: Sokka doesn't believe you can fly. But I do, Appa. Come on, don't you wanna save Aang?
(Appa growls and swims faster)
Sokka: What was it that kid said? Yee-haw? Hup-hup? Wa-hoo? Uhh...yip-yip?
(Appa growls and takes off into the air)
Katara: You did it, Sokka!
Sokka: He's flying! HE'S FLYING! Katara, he's (pause)
(Sokka looks to her and she gives him a smirk)
Sokka: I mean, big deal, he's flying.
