Based off of the trailer scenes, and what nneds to happen before 317, here's my idea for "The Southern Raiders."

• Zuko notices that Katara still doesn't trust him. He tryies talking to her, but she gets even angrier at him. She talks about all the atroscities the Fire Nation has done to her (and the World in general), and she storms away.
• Zuko gets depressed, and Hakoda tries to help. At this point, he explains the Southern Raids, and we get a flashback of the Old Tribe. (It goes through a bunch of things with Katara and Sokka as little kids. Then, of course, we see how Katara's Mother died.) Zuko feels extremely guilty, and tries talking to Katara again. He talks about his own mother, and the things that his father did. He explains that the best way to overcome problems is to become stronger. (he uses his own life as an example.) Katara agrees,a nd asks Zuko to go somehwere with her.
• So, they take the stolen Airshp back into the Fire Nation. They land in a discrete location. Then, we get teh Ninja running scenes back to Hama's village. They break her out of prison (which obviously wouldn't be that hard, since its probably just in that mountain again.) She trains Katara, and starts using her anger to make her a stronger bender. (Using the image of her mother) We get the Rain-Stopping scene.
• At this point, I'm just guessing, Hama might try to hurt Katara agian, and Zuko could save her.
• They fly back to the Western Air Temple, but of course, Azula convienently notices her old Airship. (I don't know why Azula would be in the Area, but who knows...) With stronger Airships, Azula manages to beat Zutara back to the Western Air Temple.
• When Zuko and Katara arrive, Aang, Sokka, Suki, and Toph are escaping on Appa. Hoevering near the window of the Ariships, Aang explains that The Three Stooges, Hakoda, and Chit Sang, are still at the temple. Not willing to lose another parent, Katara tries going back to the Temple. Zuko doesn't let her, and may force her to stay with Aang. he truns the Stolen Airhsip around to block Azula's airship.He manages to partially dock on one point of the Temple, and the Other Guys manage to get on. Azula gives chase, and Zuko tells Chit Sang to get the balloon out of here.
• Hence, we get the Zuko balloon jumping scene. He fights Azula on her Airship, and it ends with a huge explosion. The New Airship is destroyed, and Zuko and Azula start to fall. The Gang, on Appa, manage to catch him. Being a peaceful guy, Aang regretfully saves Azula as well. They leave her on a part of the temple and escape.
• Teh Gang tells The Other Guys to fly somehwere safe, and promises they'll do the same. That's when they head to Ember Island...
