Night time...

Naruto was at fore of the ship, looking at all the stars. "I wonder...I wonder how they're doing?"

Sasuke walked up to Naruto. "Who are you talking about?"

"None of your business!" Naruto snapped.

"..."

Flashback:

Naruto was alone as he always was after the academy, he started to walk back to his walk. "Hey! You spiky blonde!"

Naruto swung his head around, a peculiar girl was standing before him. "...um...who are you?" Naruto asked.

"That doesn't matter right now..." The girl ran up to Naruto. "Come on! Let's play!"

"Yeah Okay!"

The girl took Naruto's hand. "Let's go play fire tag at my favorite place!"

Naruto stood up from the helm and went back inside the ship where Sasuke. "How long until we get there?"

"Sevearl hours. By map the Lightning country isn't far from the northern water tribe."

"...have...you...no. Never mind." Naruto walked down the stairs back into the cabin mate rooms.

Genearal Zhao...

Zuko's only burning passion, his only drive, his only ambition was to capture the avatar. After being banished for three years finally the avatar has came back upon this world. With every cause there is an effect and now an entire fire nation fleet is looking for Aang, led by the just as cruel General Zhao.

Zhao smirked as a group of people came in. "...hm you're missing one member...the young 'artsy' one."

"He left."

(They'll still be effective.) Zhao slid a generous amount of gold towards them. "Never mind that. I want you to kill someone."

"We'll blow him up with this amount of gold. The explosion corps accepts your offer."

"Good..."

Katara...

After healing class Katara started to walk away, that was until Yugoda stopped her. "Wait. Katara...who are you marrying?" Yugoda asked noticing her necklace.

"...Oh I'm much too young. This was given to me by mother who her own mother, my grandmother, gave to her."

Yugoda took a closer look at her necklace. "It looks very familiar in fact you look very familiar to my friend Kanna."

"Wait...my grandmother lived in the Northern water tribe?!"

"She did. Kanna was suppose to be married to a fetching young waterbender lad but she left suddenly..."

"Probably because he was sexist."

Yugoda and Katara looked up. Sai was standing on a jagged piece of ice. "And why are you here?" Katara abruptly asked.

"I'm going to teach you water bending."

"..."

"But young man isn't that against the rules?" Yugoda asked.

"I don't particularly care. So Katara...are you coming?"

Katara nodded and the two of them ran off to a secluded place. Even though Katara knew nothing about Sai...she still thought, she still believed she could trust him. Let's hope she made the right choice.

Sai took out his short sword and stuck in the ice. (Just in case...) "Ok then Katara. Our first move is the ice water whip." Sai held out his arm and water just attracted to him like a magnet, eventually creating a long whip like structure.

Sai then brought his arm down making the ice crack and break on the snow. "Your turn."

Katara held out her arm, the water eventually came to her but then immediately dropped back down. Over and over it was mere trial and error. "...ugh...Sai why are you making me do this? It's so hard!"

Flashback:

It was another nice sunny day except it was freezing outside. You know one of those days where it's sunny out, not a cloud in the sky but when you walk out it's below zero? Northern water tribe was having one of those days.

Sai and Pakku stood face to face. "Remember Sai this is a very complicated move and it's very challenging."

Sai's face as usual was expressionless. "Why sir are you making me do something that hard? I'm not that good of a waterbender."

"Because Sai you are a...my special student and I believe you can do this because you are very talented."

Sai 'smiled'. "Because Katara you're a very weak waterbender but you have lots of potential."

Katara had on that same peeved face from before. "Wait...weak?"

"..." (That's not the expression I thought I would get...)

"Why I! Whoever taught you manners Sai should be-"

Sai walked over and picked up his short sword. "Except you can't be mad at anyone since no one taught me manners."

Sai 'smiled' again. "Have a nice night." Then Sai disappeared into the darkness.

Katara merely sighed. (I know you're risking so much for me but...) "You're such a mystery Sai."

Zuko...banished fire nation prince...

Zuko was in his ship, writing something on a scroll, there was a knock on the door and Iroh, his loving Uncle, stepped in. "Your crew...wished you goodbye."

"...They were traitors anyways. Good riddance."

"Well you're welcome to take a leisure stroll with me in this beautiful night nephew?"

"No!"

Iroh sighed and went out to take a walk alone, as Iroh was taking a lonely walk the explosion corps planned to destroy Zuko's ship. Gari, the leader of the explosion corps, held several bombs in his hand. "These are C2 bombs. They'll destroy his boat."

"Where will we plant them?"

"Around the base of the ship."

Zuko laid awake in his bed, feeling betrayed by his cruddy shipmates. Suddenly there was a random footstep. Zuko threw his cover on the floor and silently walked out of his door. Zuko noticed a white looking thing on the deck, he picked it up. "What's this...wait...clay?"

*BOOM*

In a quick second the entire ship exploded, Iroh heard the noise and ran back to the docks only to see his nephew's ship in smoldering ashes. "ZUKO!"

The northern water tribe...Sokka and Yue...

Sokka ran up the bridge where Princess Yue of the northern water tribe awaited. He held a carved animal thing in his hand. "For you." Sokka presented.

Yue moved a piece of her white hair from her face. She tightly held on to her gift. "A bear...thank you Sokka."

"Actually it's a fish."

Yue handed the carving back to Sokka. "I made...a mistake." She then ran off, crying.

Sokka threw the carving into the water. "Stupid! Why am I not an artist?!"

The next day...

Aang, Katara, and Sokka were back at square one. Pakku was a major problem and the situation with Yue was also another situation on the table. Aang got out the tea set and poured a cup of iced tea for everyone. "Hm...snow flavored." Aang read. "I hope this stuff taste good."

Sokka slumped in his chair and slammed his head on the table. "This is so troublesome! I'm so confused!" Sokka yelled.

"Sokka! You're going to break the table!" Katara scolded, she picked up her tea and sipped some of it. "...not bad."

Aang brought up a chair next to Katara. "So Katara, what're we going to do about Pakku?"

Katara set down her tea cup and slightly smiled. "Actually...Sai..."

Sokka slammed his hands on the table. "Yeah! Sai is such a jerk-face!"

*knock*

*knock*

Sokka stood up and opened the door. It was Sai of course. He 'smiled'. "Hello."

Sokka groaned. "Sokka!" Katara scolded. "Sai come in."

Sai walked in the house. "Aang we start training in about half an hour." With that Sai left again just reappear then disappear.

"...right so Katara..."

"It's fine Aang." Katara walked out of the house. "Besides I have to get to my healing class."

Aang sighed. "Girls are so confusing."

"You got that right!" Sokka quickly agreed.

Half and hour later...

Aang met up with Sai up on a snowy hill. "All you have to do avatar Aang is push and pull the water. Simple as that." Sai held out his arms and demonstrated an easy technique. "Now you try."

Aang held out his arms and slowly moved it back and forth. "..."

"Avatar Aang don't force it. Just slowly push and slowly pull."

"What?! You're so confusing!"

"Hm I really not good at these sorta things. I'm not sure why Pakku made me teach you and not Master Chōjūrō."

"...ok...hey I got it!" Aang exclaimed. "...that was actually kind of easy though."

"Good job. Next technique is freezing." Sai water bended the water out of his ouch then froze it. Sai trailed off. "I guess with going into states of matter you could also do evaporation techniques."

"What?"

"Then you have to learn to change Ph level."

"...Listen Sai let's just do the basics. I'm only a beginner."

"No. You're the avatar."

Later that night...

Katara got up and walked to the same place as before when they first started their training. "So Sai what's next?"

"...well...did you figure out the technique from yesterday?"

"Well not really..." Katara admitted. "But I'll keep on trying!"

"Well then. We can practice-"

"What're you doing?" Pakku asked, randomly appearing.

Katara and Sai looked to the edge of the cliff where Pakku was standing. Sai didn't say a word to help his case. "..."

"You disregarded our culture, my wishes, and my teachings Sai as if they were nothing. You are done being my apprentice and you are done teaching both Katara *cough* and Aang. I can't even look at you anymore."

"No master Pakku...please Sai didn't-" Katara cried.

"Shut-up." Pakku snapped. "And Sai I will put in guards to watch you. I don't think I can even trust you." Then he left.

"..."

"Aren't you going to say something Sai?"

"...what is there to say?"

(He risked everything for me...why?) "...Sai...why..."

Sai looked up at the shooting stars, twinkling in the night sky. "I'm still going to teach you water bending."

"But...you're going to be shunned and mistreated...beat up..."

"I don't particularly care. I guess this is something my brother would do."

"Your brother? You have a brother?"

"Well no he died. But...he told me to be like this."

Flashback:

"You have to be selfless in every way possible. Don't listen to what they say because I know deep in my heart it's wrong."

"I...will try to..."

"No. You will. Everyone is equal."

Katara walked over closer to Sai. "I'm sorry Sai."

"You don't have to be."

"I will because that is what a true friend would do."

"...we're...friends?"

"Of course we are Sai."

The next day...

Katara and Aang along with Sai ran up the stairs to see if they could change Pakku's mind by talking to chief Arnook. Aang swung the palace door open. "Cheif Arnook!" Aang yelled.

"Hm? What is it?"

Pakku also happended to be there, once he saw Sai's face he simply nodded his head in disappointment. "I want Pakku to reconsider what he said and let Sai teach us!" Katara demanded.

Pakku and Arnook nodded to each other. "Actually Sai is forbid to teach any of you. Maybe if you apologize for your action, Master Pakku might reconsider his punishment and may continue training with the avatar."

"No! I will never apologize to you! Pakku I challenge you to a fight!" Katara yelled.

Sai looked at Katara. "...No. I want to fight him."

"But I have to prove-"

"You don't have to prove anything. You're a better waterbender than Pakku ever will be!"

The room was silent for a bit. Such a statement was so strong, a woman being better than a man was never heard of in the Northern water tribe.

Pakku and Arnook looked at each other. Pakku's eyes locked onto Sai's coal black eyes. "Sai you are here by banished from the Northern water tribe and you are to never step foot in the north ever again."

Sai expression was as emotionless and stoic as ever. "I'm glad." He turned around and looked at Katara. "Bye ugly."

Then he walked off.

Katara couldn't take it anymore, tears dropped down. "Pakku! I want to fight you right now! If I win Sai will come back and stay here as long as he likes!"

"This is his home! You can't take that away from him because that's...all he has. He has nothing else expect for the Northern water tribe. How could you?!" Katara cried.

Pakku stepped down. "Very well. We will fight."

Naruto and Sasuke...

After several hours on sea they were in reach of the Northern water tribe. And you know what all that time they spent arguing and fighting. Naruto took out a telescope. "Yes! I see the Northern water tribe!"

Sasuke walked over and snatched the telescope out of his hand. "Let me see that! I told you Naruto we're near."

Naruto re-snatched the telescope. "Damn you idiot give me that!"

"Shut-up!" Sasuke quickly let go making Naruto fall down and making the telescope fall off the deck.

"...! You idiot!" Naruto barked.

Sasuke's hand extended to Naruto. "Sasuke..."

"Hurry up I don't have all day!"

Sasuke pulled Naruto up but he still had a pout-pout face. "Bah. I could've done that myself!"

"Whatever. Now Naruto we need to do this perfectly if we want the telescope."

"Wha?! Can't you walk on water?"

"Only at lightning enhanced speed." Sasuke quickly knocked Naruto down, he picked up Naruto by his feet then dangled him down to the water.

"DAH! Sasuke what're you doing?!"

"Grab the damn telescope already baka!"

Naruto reached for the telescope bobbing up and down. "I...I CAN'T REACH IT!"

Sasuke flung Naruto back up on the boat. "Whatever. We're here anyways."

Naruto looked up. Finally they made it to the Northern water tribe when things were as tense as ever.

Zhao's head Fire nation ship...

Zhao was sipping tea in the quarters of the ship. There was a knock at the door and Iroh came in. "My nephew was killed during an explosion." Iron stoic-ly stated.

Zhao turned his head so Iroh would see his smirk. (It didn't trace back to me...heh) "I'm devastated Iroh."

"I accept your offer as second general of your fleet."

Zhao stood up and set down his cup of tea. "Very smart Iroh."

Katara and Pakku...

Katara and Pakku faces each other. The air was thin and tense as it always was. "Why would you be so harsh to Sai?" Katara as calmly as she could asked.

"Because Sai is like a son to me. Ever since I found him alone out in the cold that one day along with his brother I've felt a strong bond towards him. Then he breaks it." Pakku explained.

"...that is no reason to treat him like a piece of trash."

"Let's begin shall we? Katara I'll let you go first."

Angrily, Katara raised her arms making a huge amount of water rise from the surrounding pools. Pakku held out his palms making the water jet towards her. Katara held out her palms as well, she clenched her fist making the water freeze. Katara jumped on the frozen water and held out one arm, water attracted to her arm to make a whip, then she froze it.

"For you Sai..."

Pakku broke off some of the ice and shot it and Katara, Katara sheilded the incoming ice shards with her frozen water whip.

"...For what you taught me...I won't ever forget what you taught me..."

Katara swung her ice whip at him. Pakku raised her arm and clenched it in his hand, Katara fell down on the snow, hard. Katara lifted up her free arm and water rushed behind Pakku's back.

"THIS IS FOR YOU SAI!" Katara yelled, water splashed on Pakku, in less than a second she clenched her fist and froze the ice. Freezing Pakku.

Pakku smirked. "You're good...for a girl." Then Pakku noticed something lying on the ground, he cracked the ice with his free hand and picked it up. "What is this?"

"That's my necklace." Katara darkly stated.

"No it's my necklace that I made for Kanna...sixty years ago."

Fire nation ship...

Iroh walked out of Zhao's quarters, then walked past a solider. "It worked perfectly. He doesn't know anything." Iroh whispered.

The solider took of his face plate revealing a scarred face. "That you uncle." Zuko was sincere in his words. He put the face plate back on.

"Stay hidden Zuko until we reach the north pole." Iroh warned. Then he continued on. He looked back and warmly smiled. "And good luck."

Northern water tribe...

Pakku remembered what happened that day sixty years ago. "We were to have an arranged marriage but she left to the South Pole."

"It's because she didn't want to be tied down by the tribe's customs."

With that Yue ran off, yes she happened to be there as well. They fought just outside the palace. Sokka ran after her. They ended up back where they started: at the bridge. Yue's tears dropped down into the cold river.

(The burden I carry of being a princess...) She felt a strong yet comforting hand on her back. "Sokka?"

"I just wanted to say how beautiful you are. Ever since I saw you that day." Sokka looked deep into Yue's pale blue eyes. "I never even thought a girl like you would fall for someone like me."

Suddenly Yue's lip's locked onto Sokka's. It was the first decision she's ever freely made. She softly let go as her face turned several shades of red.

"Huh? Yue what was that for?" Sokka asked, bewildered but happy to say the least.

"Sokka...I love you but...we can't be together." She pulled down her fur thing revealing a betrothal necklace, like the necklace Katara wears. "I'm engaged." With that Yue ran off, crying once more.

Naruto and Sasuke...

Naruto and Sasuke finally stepped foot in the long awaited Northern water tribe. "Alright! I was getting sick of the sea!" Naruto yelled.

Sai happened to be near the docks, the first thing he saw was a flash of blonde hair and black but that didn't matter when half the world had the same color hair as you. "Is that...the yellow lightning? Didn't he die?" Sai wondered.

Katara and Pakku...

Pakku finally handed the necklace to Katara. "I want to find Sai now. I have to apologize to him."

"I'm coming too."

"Me too!" Aang dittoed.

The three ran off to the docks thinking he left the northern water tribe. (I hope I'm not too late!) Pakku thought to himself as he ran through the snow.

Naruto...

Naruto put his hands behind his head. "He-he! This place is awesome!"

(Why is he so happy?) "Wait up idiot. You know they'll kill firebenders but lightning...I'm not sure."

Pakku...

Pakku punched a block of ice, revealing the docks. "We're here! Sai!"

Sai...

Sai looked back when he heard his name, it was Aang, Katara, and Master Pakku running towards him. (It's them but...) Sai looked to yellow lightning guy. (...but...)

"Hey who's that guy?" Naruto asked.

Pakku stopped when he saw Naruto. "...it's a...Lightning...bender..."

A/N: The Lightning country is highly based off of Japanese culture just like the fire nation, their main economy thing is fishing and boating. Hence why Sasuke knows how to use a boat.

Speaking of that, many boat terms were used. Here's a little boat dictionary.

Fore=front of ship

Helm=spiny wheel thing you use to steer

Quaters=small room you use to do important stuff

Deck=floor of ship (you guys know dis though:)

I know this chapter was barely about our main hero but that's how it is sometimes.
