Author's note: This is my first Avatar fanfiction evah! Woo hoo! This takes place after The Water Scroll, but just assume that all the forms of waterbending are not written on that one scroll, and even if they were, they would still need training.

Summary: One-shot. Aang and Katara find someone to help them learn waterbending, but is he all that he seems? Prepare for randomness! Aang/Katara/OC.

Disclaimer: I don't own Avatar: the Last Airbender. If I did, this would be an episode. I also don't own the law ninjas. Which is to bad, 'cause they're cool.

Narrating.

"Speaking."

'Thinking.'

Book 1: Water

Deception (Dun Dun Dun!)

Aang, the avatar, the last surviving airbender, the world's only 112-year-old boy, link between the mortal and spirit world, owner of the world's largest rubber band quilt… Wait, that last one's not true… Well, anyway, he and the others were riding Appa over the ocean heading for the North Pole.

"Okay guys," Katara said, turning to Aang and Sokka, "Since the Fire Nation's still after us, we'll need to keep a low profile. Does anybody have any ideas for how we can keep from drawing unnecessary attention to ourselves?"

"Ooh! Ooh! I know!" Said Sokka enthusiastically, waving his hand in the air.

"Yes Sokka?" The young waterbender asked, turning to her brother.

"We…" Answered Sokka. "Can start a rock band!" He then pulled out an electric guitar and started playing it.

"That's the most idiotic idea I've ever…" Began Katara, before Aang cut her off.

"Cool!" Said the hairless lad, pulling out a saxophone and rocking along with Sokka as Momo played on the drums. Were they got this stuff I'll never know.

"I'm surrounded by idiots." Katara observed.

"Rockin' idiots!" Corrected Sokka.

Meanwhile, on a Fire Nation ship, the exiled Prince Zuko watched the flying bison that carried the unsuspecting rockin' idiots.

"Soon," The scarred teenager said, "I will be able to put my plan into action and victory shall finally be mine. If only…" He sighed. "She was here." He was referring to the warrior girl he had glimpsed on the island of Kyoshi. He had a crush on her ever since. Sure, her hair was pretty short, with only that little ponytail. Sure, she was part of the Earth Nation. Sure, he didn't even know her name, or her his. But still, Zuko couldn't help thinking about her.

A/N: Bet you're dying from the awkwardness, huh? (In case you're slow on the uptake, he thought that Sokka in the Kyoshi warrior uniform was a girl.)

'Oh well,' He thought, 'I might see her again someday. For now, I must prepare to execute my genius plan.'

"I like tea." Said his uncle Iroh.

424242424242424242424242424242424242424242424242424242424242424242

"Well, here we are." Said Aang. "The North Pole."

"Now all we have to do," Said Katara, "Is to find someone to help us hone our waterbending skills!"

"Good luck with that." Said Sokka sarcastically. "There's no one here for miles!" And, for once, he was right. The area where they had landed was a barren, icy wasteland devoid of life. Except for one figure that Sokka suddenly spotted heading towards them.

"Sweet mother of potatoes!" He exclaimed, pointing. "It's Santa Claus!"

"Ho, ho, ho!" Said the rotund saint.

Sokka quickly ran up to meet him. "I've already made a list!" The boy explained. "First off, I want pony, a new boomerang-thingy to go with this one, swordchucks, a… Hey, wait a minute! Come back!" But Santa, not wanting to have to listen to some random kid's demands until at least December, had fled.

"Phooey." The teenager said.

"Well, I have to admit, that was pretty cool." Said Aang. "But where'll we find someone to teach us waterbending?"

"Did someone say waterbending?" Asked an unknown voice. "I think I can help."

They turned around to a handsome teenage boy, with long, blonde hair and piercing blue eyes. Katara nearly swooned when she saw him. Aang saw, and immediately decided that he hated that guy, whoever he was.

"My name is…" Said the pretty boy, pausing for effect. "Garistew." Again, Katara nearly swooned.

"I know all six waterbending techniques." Garistew explained. "Perhaps I can teach you. My igloo is only a short walk away, if you want to come."

"Sure!" Said Katara, unnervingly enthusiastic. Aang internally seethed. Still, teaching was teaching, and he needed all the help he could get if he wanted to master all four elements. So, he begrudgingly fallowed Garistew and Katara of into the distance. Sokka fell into a plot hole and will not be heard from until he is needed to further the story. Sorry man, that's how it goes.

424242424242424242424242424242424242424242424242424242424242424242

And so, for the next few days, Garistew taught Katara and Aang the finer points of waterbending. Most of them involved water. Anyway, Katara continued to swoon over Garistew and Aang continued to be jealous about it. There's really no need to show you all that, it's kind of repetitive. But that all changed on the fifth day…

"And so that's how all the people I ever cared for perished," Garistew explained to a teary-eyed Katara, "Leaving me to my pity-inducing and strangely attractive angst."

Katara sniffled. "Isn't that sad Aang?" She asked to the young monk, who was still busy being jealous off in a corner of the igloo. Wait a second, igloos are round! They don't even have corners!

"Whatever." Said Aang bitterly from his physical impossibility. 'Stupid Garistew and his stupid angst.' Thought Aang. 'What does he have that I don't?'

'Hair, for one thing.' Said a little voice inside his head.

'Be quiet.' Aang thought to the voice. 'My Q-ball head is adorable!' And indeed, it was.

"Well," Said Garistew, "Now that I've taught you the first four techniques of waterbending, I suppose it's time to…"

"Teach us the fifth one?" Katara tried.

"Actually," Responded Garistew, "I was thinking more along the lines of… TURN YOU OVER TO THE FIRE NATION! BWA, HA, HA!" Oh no! Garistew has been deceiving them? This must be the part with the deception! (Dun dun dun!)

"Garistew!" Katara cried. "How could you do this to us?"

"Foolish girl who is a fool!" Garistew laughed. "I am not Garistew! I am…" He ripped of the surprisingly convincing costume. "Prince Zuko! Ha, ha, ha!"

"Wait…" Aang said, confused. "If you're Zuko… Then how did you do waterbending?"

There was a long, awkward pause.

"Anyway," Zuko continued, "You shall now be vanquished, avatar, by my fiendishly fiery flame of freakish fury!" He then unleashed a huge fireball at Aang.

Just when the ball of flame was about to hit Aang…

"Nooooo!" Shouted Sokka as he jumped in front of Aang (Good to have you out of that plot hole, buddy!), taking the blow.

"Sokka!" Shouted Katara as she and Aang rushed to his side.

A/N: No, this is not one of those "character death" fics. Sokka is one of my favorite characters, up there with Uncle Iroh. He'll be okay, just watch and see.

"I… I… Did it." Coughed Sokka.

"Yes, Sokka," Katara said tearfully to her brother, "You saved us all."

"No… I mean…" Continued the Water Tribe teen. "I… Was… Able to do… This!" He then enthusiastically lifted up something that he had been holding, his signs of injury now totally gone. "See?" He said. "By exposing this cheese and bread to the fire, I created an entirely new type of food! I call it… Cheese toast!" He then began to happily eat his new creation.

"Yes, enjoy your toast of cheese while you can!" Prince Zuko shouted, drawing their attention back to him. "You have not seen the last of me!" He then used a fireball to make a hole in the ceiling of the igloo. The roar of helicopter blades filled the room and a rope ladder fell through the hole. "I'll be back!" Shouted Zuko as he grabbed onto the ladder and was hoisted through the hole and into the sky.

"Wait a second!" Exclaimed Aang. "Helicopters haven't been invented yet!"

Zuko's ride to freedom disappeared in a puff of logic and the exiled Prince fell back through the hole, rope ladder in hand. "Ah, Crud." He said.

424242424242424242424242424242424242424242424242424242424242424242

"All right boys, take him away!" Aang said cheerily to the law ninjas that had arrived to apprehend Prince Zuko.

"Hey," Said Sokka, approaching the disgruntled Zuko, "I've got a question."

"What?" He asked.

"If you were a prince, but now you're banished… Does that make you the firebender formerly known as Prince?" Sokka asked.

"Oh, like you're the first person to use that joke." Zuko answered sarcastically. Then he took a second look at Sokka. "Say," He said, "You look a lot like a warrior girl I saw on Kyoshi. Are you her brother or something?"

"I don't have any relatives on that island." Sokka responded.

"Oh well, then." Sighed the firebender as the ninjas dragged him off.

"That was odd." Sokka mused to himself. "I don't remember any of the girls there looking particularly like me. Unless…" A look that blended realization, shock and disgust crossed his face. "Oh my whatever deity we worship here!"

"Well," Said Katara, turning to the others, "We sure got through that little misadventure. What should we do now?"

Aang looked at Sokka. Sokka looked at Aang. Momo looked at Sokka. Sokka looked at Momo. Momo looked at Aang. Aang looked at Momo. They all looked at Katara.

"ROCK 'N' ROLL!" Sokka and Aang shouted in unison, pulling out their instruments.

"Come on, Santa!" Added Aang. "Jam with us!"

"Ho, ho, ho!" Exclaimed Santa Claus, picking up a bass guitar and playing along with Sokka, Aang and Momo. And so they rocked, those rockin', rockin' idiots.

A/N: Man, that was fun! And it only took about two days to make! Now for a game of word association! Review… Cookie! Flame… Monkey attack! Fudge… Yummilicious! Cheese… Pants! Okay, that was random, but you get the point. Before you leave, have some bonus footage for the end of the episode!

424242424242424242424242424242424242424242424242424242424242424242

Next time on an all-new Avatar (not really)…

"And so," Said the leader of the warriors preparing to fight against the Fire Nation, "The plans have shown that a small, bison-shaped vehicle would be able to get close enough to the death comet to fire a projectile into this air vent, causing a chain reaction that would destroy the station!" Everyone looked at Aang.

"I hate Star Wars parodies." He sighed.

424242424242424242424242424242424242424242424242424242424242424242

Okay, now it's over for real.
