The Last Omnitrix Weilder (ATLA X Ben 10)

The Desert

Aang: (enraged) How could you let them take Appa Why didn't you stop them?!
Toph: I couldn't! The library was sinking! You guys were still inside and -(Toph swings her arms wide.)
Aang: You could have come to get us! I could have saved him!
Toph: I can hardly feel any vibrations out here. The sandbenders snuck upon me and there wasn't time for -
Aang: You just didn't care! You never liked Appa! You wanted him gone!

Ben: hey I did some work to 

(Katara approaches the three in an attempt at peacemaking, and places an arm on Aang's left shoulder.)

Katara: Aang, stop it. You know Toph and Ben did all they could. they saved our lives.
Sokka: Who's going to save our lives now? We'll never make it out of here.

(Camera swings to Sokka, who turns towards the others and motions to the endless desert with an arm.)

Aang: That's all any of you guys care about: yourselves! You don't care whether Appa is okay or not! (Aang stalks off, sulking angrily.)
Katara: We're all concerned, but we can't afford to be fighting now.
Aang: I'm going after Appa.

(Aang flies off. Katara calls after him, running towards the spot from which he took off.)

Katara: Aang, wait!

(Cut to a view of the sky, with a view of the crater where the Library had been and Aang flying off.)

Katara: We'd better start walking. We're the only people who know about the solar eclipse. We have to get that information to Ba-Sing-Se.

(Camera, looking up towards the sun, returns to Katara, with Sokka visible to the right. The group wanders out into the desert.)

Sokka: You think if we dig out the giant owl, he'll give us a ride?

Ben: Um, Library sunk, it was like ten minutes ago

(Cut to Katara, Ben, Sokka, and Toph. Katara is seen leading the rest of the crew, minus Aang and Appa, thought the desert. Occasional small plants dot the dunes. They are clearly hot, dry, and tired. Sokka tries using Momo and his wings as a hat. As he slows, Toph bumps into him, knocking Momo off Sokka's head.)

Sokka: (breathing hard) Can't you watch where you're -
Toph: No.
Sokka: Right. Sorry.

(Katara turns to encourage the others.)

Katara: Come on guys, we've got to stick together.
Sokka: If I sweat any more, I don't think sticking together will be a problem.

(Sokka tries to gently pull himself and Toph apart, but Toph cuts to the chase and knocks Sokka down, disconnecting them.)

Toph: Katara, can I have some water?
Katara: Okay, but we've got to try to conserve it.

(Katara bends water from her bag and suspends it between her and the others. She then directs it to each mouth except her own. Sokka swishes the water a bit, and then swallows with a face. He clearly is not impressed with the taste.)

Sokka: We're drinking your bending water? You used this on the swamp guy!

Ben: Wait, what? ew
Toph: It does taste swampy.

(Cut to a shot of Momo smacking his lips before he lets out a displeased burp. Katara motions her sense of helplessness.)

Katara: I'm sorry, it's all we have.
Sokka: Not anymore! Look!

(Sokka makes a discovery, pointing to a large cactus a little off their path. He walks up to it, cuts a piece off with his knife, and drains the liquid content into his mouth. Momo does likewise.)

Katara: Sokka, wait! You shouldn't be eating strange plants! (Katara grabs Toph's wrist and runs over to Sokka and Momo.)
Sokka: There's water trapped inside these! (Sokka holds up some cactus for Katara, but she backs away, pushing Toph back as well.)
Katara: I don't know...

Ben: people say that cactus juice can make you see some weird stuff
Sokka: Suit yourself. It's very thirst-quenching, though.
