A/N: I changed my mind. Since I got at least some reviews, I'll update. Although, with 613 hits and only 11 reviews, it could be better. But now, the next and potentially the last chapter.
"I choose KATARA!" Zuko shouted.
"Really? I thought you would say that, so here's another thought. Choose your honor, and the Water peasant," she spat in Katara's direction, "Can be a slave. You can have her…" She paused, "And your life." She concluded.
"NO! I WON'T LET YOU HURT KATARA!" Zuko shouted, shooting fire in every direction, and hitting Katara by accident. She fell over, unnoticed.
"Very well. Then I can't be held responsible for your death." Azula spoke slowly, thinking her words out.
Right as Azula took her fingers to form lightning, Aang awoke. He looked all around and saw Katara lying on the ground, barley moving.
'You have to let her go! … If you leave now, you won't be able to go into the Avatar State at all! … You have to let her go! … You have to let her go!' The Guru's words of 'you have to let her go' spoke over and over again in Aang's head.
Aang slipped unnoticed into a pile of Earth, created an Earth Tent, and meditated.
'Let her go'.
"I'm sorry, Katara." Aang whispered before slipping into the Avatar State.
Aang's Avatar State got up, and Firebended around everyone except for Iroh, Zuko and Katara. After all, Zuko had offered to save Katara and Iroh had been a good Ally for him.
After all of the other people were dead, Aang slipped out of the State, walked over to Katara and Zuko, who had fainted next to Katara, picked them up, and Waterbended the three of them up the water fall.
"No, Azula. Don't hurt the girl. I love her." Zuko muttered in her sleep.
"No, Zuko. I love you." Katara muttered in her sleep.
Aang walked over to the two and laid the letter that he had written and walked out.
Katara, Zuko, Toph, and Sokka:
I have seen how you all protect each other. Appa, Momo, and I have left. We are going to the Fire Nation to stop them. Azula is dead. Nobody knows of the plan except you, me, Iroh, and the Earth King know about the plan.
Zuko, protect Katara. I see now why she can never love me. And Sokka, you protect Toph. Even if you can't see it, you two are good together.
Goodbye you guys,
Under the letter, there were two paw prints, one big, Appa; and one small, Momo. All over the letter, there were tears. It was clear that Aang had been crying during writing the letter.
Aang got on top of Appa, called "Yip-Yip!", and flew off to the Fire Nation to stop them.
A/N: So there you have it. That's the end. I kept Iroh alive so he could train Aang as a Firebender. I hope that this is a good ending.
