(A/N: I just saw the Avatar season finale (I think the show ended too.) and I thought it was missing what came next. So even if they continue, here's my version. This takes place from right at the end on (When Aang and Katara kiss) to whenever I feel like.)
3rd person Aang POV
Aang looked out thoughtfully out from the balcony in the tea shop in BaSingSe. He heard some talking from inside.
"Hey, I am not that fat! I've slimmed down a lot!" Complained General Iroh to Sokka and his painting.
Katara walked out of the tea shop and on to the balcony with Aang.
She walked up to him slowly, smiling.
They turned to face each other, and hugged.
Then, they kissed.
"So, you saved the world. What do we do now?" Katara asked, blushing.
"Um…I don't know." Said Aang, looking as if he'd been hit in the head.
Katara giggled. Wow, she's pretty. Aang thought lovingly.
"So, um…" Aang said, not wanting more world-saving to do. "Does…this mean we're…you know…together?" Aang asked, blushing.
"Yeah." Katara stated. "I guess it does."
"You know what I want?" Aang asked, now confident.
"What?" Katara asked, intrigued.
"I want…someone else…just like me. I want to have an air bender as a friend."
"Well, if you learned all four types of bending, I'm sure you can teach somebody one." She said encouragingly.
"But who? Who doesn't know how to bend?"
They both eyed the water tribe boy poorly painting a picture of a happy scene in the tea shop.
"But he doesn't really want to bend." Aang said.
"I'll do it," Katara said, confidently. "If I can do it, then you can teach it to other people too."
"Alright, I'll try." Aang said uneasily.
"Okay. The first step is proper stance." Aang went into his air bending stance.
"Next, move your hands…well…make a circle…then…um…well…like this." He demonstrated the proper way to make an air strike. "Now you," He said, smiling.
Katara attempted to make a proper air bending stance. It was incorrect.
"No, no." Aang said eerily teacher-like. "Like this." He said, getting into stance.
She tried again. It was still incorrect. "No, but better." Aang said. He went over to her to examine what was wrong.
He saw her legs were too straight.
"Bend your legs juuust a bit." Aang said, putting his hands on her shoulders, gently pushing downwards. He blushed a bit. "There. Perfect!" He said.
"Now, take a deep breath in through your nose, and exhale while you move your palm forward."
She tried it. Her hand went too high.
"No, that was a bit high. Here," He said, moving in front of her. He put his palm out. "Now, do the same thing, but give me a high-five."
She did it again. Luckily, it worked. Unluckily, it sent Aang flying backwards.
"Aang!" She said, running over to him. The rest of the gang ran out of the tea shop frantically.
"What did you do?!" Sokka yelled at Katara, frowning.
"I hurt him with air bending! Oh, Aang, are you okay?"
"Yeah, I'm fine. But wait. You hurt me! That means you can air bend!"
"Whoa, whoa, whoa. Katara can air bend? Since when?" Sokka said, disapprovingly.
"Since he taught me." Katara said, irritated at Sokka.
"Oh. Can I go next? Please?"
"You didn't even want to water bend. Why would you want to air bend?"
"Because then I'll be just like Aang! And he's the avatar! He defeated the loser lord!"
"Fine. Aang, can you? Or did I hurt you…" Her voice trailed off.
"No, I can do it." Aang said, using air bending to lift him.
And so Aang spent the next half hour trying to get Sokka to do the right frigging stance and the other half trying to get him to align his exhaling with his movement.
But hey, If Katara could do it; maybe there was hope for Aang. And hopefully Sokka too. Sokka really needed it.
(A/N: This is my first Avatar fic, and it's definitely not a one-shot. More coming soon!)
