When they got there they went where she had to take them.

"You're probably wondering why we're at the Southern Air Temple right? Well the reason we're here is because Aang is back and is going to take my place as the avatar." Korra said.

Then they saw someone come in dressed like he were getting his tattoo. He took down his hood and everyone was amazed. Katara's eyes were watering with joy. Korra had had Katara, Sakka, Toph and Zuko stand together.

"You may be wondering how and why I'm back. I'm back to switch with Korra. Just like when Roku was the avatar before me, I was strong enough to see and hear him. But before my accident I was fine. Then after that the connection was destroyed for weeks. I had lost my Avatar State for a while. Then when my back had hit something hard enough to fully get back. Roku, Kioshi, Koruk and Yangchen came up with an idea, have me switch with Korra. Since I was the avatar before her I have everything still, from the four elements to the Avatar State. The first one I mastered was air, I was only ten years old and earned my tattoo."

"Usually you don't find out you're the avatar until you're sixteen. But I found out when I was twelve because they thought the war was coming. After everyone hearing I was the avatar I lost all my friends because it was unfair if they did something."

Then he shut his eyes and sighed.

"I had to keep training, and a lot of other things. One day the monks said they were going to separate me from my mentor. After overhearing that I left and never saw them again. It was a storm that I was flying in and then I was under the water and got into the Avatar State. After that I somehow froze me and Appa for one hundred years."

He looked at his friends smiling.

"The first person I saw was Katara, she asked me if I had any idea of what happened to the avatar after a while. I was too scared to say yes, so I said no. But when Zuko came to try and get me I gave in and they found out."

Zuko looked at him feeling ashamed but saw him smile and shake his head. Zuko smiled and nodded.

"When everyone heard I was back they were surprised. When they found out it all started. I started waterbending with someone different, found the perfect earthbending master and surprised at who taught me firebending."

Some people stared at him confused.

"Water was a little tricky in the beginning but I got it eventually. Earth was always the hardest element because it's my opposite of air. But eventually I got that and had a few tricks with it. Fire I was scared of doing but I got that eventually and just like earth I got a few tricks." He winked at the four of them when they smiled.

"The Avatar State took me forever because something happened while I was finally getting it. While I was fighting Ozai I got hit hard where my chakra was messed up and that got it fully mastered. I got into the Avatar State and took it from there. Instead of killing him I used energybending and got rid of his bending."

"Within a year I had mastered everything, the four elements, Avatar State and some extras. The other ones I learned were energybending, mettlebending, lightningredirection, lightningbending and I can use bending without sight. The people that taught me how to bend everything is different than the others except for airbending. My teachers were Katara, Toph, Zuko and a lionturtle." he said.

Everyone stared at him then the four people across from him and back.

"I know they were young when they taught me but I only had until the end of the summer to get everything. Now there's one more thing I can do for you four in repay. Sokka, Toph, Zuko, Katara can you come here for a minute?"

So the four of them went and stood in front of him.

"You have an option of staying how old you are now, or turning back into what you were when we met." he said.

They said they would switch so he used their elements and made them just like they did when he first came back. Since Sokka can't bend anything but was Katara's brother he used water.

"Now, as for Korra I need to make it correct, I need to energybend everything but waterbending. I feel awful about doing this but Korra thinks it's a good idea also." So he turned around and looked at her. "Alright Korra, are you ready to become a normal bender?" he asked.

"Yes, Avatar Aang it will take a while but it's worth it." she said.

Aang put one hand on her heart and the other on her forehead, took a deep breath and energybended. Just like what happened with Ozai, he fell on his knees for a second and felt Raava go back into him. He saw Katara's face, he shook his head and said, "Don't worry, it just happens when you're young and do it."

So she nodded. After he stood up he had her try to waterbend to make sure she could still bend water. When she did he was glad it had worked.

'This is going to be interesting. Me being twelve but a fully realized avatar without lessons this time.' he thought.
