Chapter 2.

It was taunting her.

Everywhere she turned, it was there, sharp in her thoughts, burning a hole through her mind. It was blue, reminding her of her past, her ethnicity. Most of all, it was beautiful, just like the one who used to wear it. Her mother. Just thinking the word sent a jolt down her spine.

Her mother was a kind, gentle, lovely person. Her mother was brave, if she was asked several years ago, she would of of said that her mother was her hero. But now, now no one is her hero, she is to far from being good, her innocence to never be saved. Instead of playing in snowball wars with her brother Sokka, she was walking along an area full of caves, caves carved by ancient lava flows. Completely alone.

It was dark, very dark. The stars were just starting to shine through the darkening sky; the moon was slowly reaching its maximum brightness, eventually giving off enough light to see. Katara was well adjusted to dark places, dark areas, and especially dark times. Only, on this night, Katara didn't expect to find a light at the end of her dark path.

Sure enough, there was yet another cave. It was none to different than the others except for the fact a light glow was coming from the mouth of it. Faintly, the soft nightly breeze was carrying soft tunes of fun energized music. It seemed happy, unsettling her dark mood. Another noise was added to the breeze, only this time; it was soft giggling laughter, coming from what sounded like a party, in a cave. Someone's having a cave party? How odd. Katara mused, a slight smirk on her face. It was at that moment, she decided to crash their party. Yes, nothing like an elite assassin joining in on some teenage, hormone crazed, party.

As Katara neared the entrance, a brief wave of applause filtered out of the cave. Probably from a dance, or song of some sort. One thing kept bugging on her mind as she walked closer to the cave, wasn't dancing illegal among the people of the Fire Nation? Katara was quite sure that maybe a cave party might be within that rule of illegality. But who was she to judge? She defied the law of all the nations, -except for the Fire Nation-, slaughtering innocent, and guilty people.

Everyone grew incredibly still when her silhouette lined the entrance of the cave. The music ended abruptly, dancers froze on spot, some falling over from pausing in an unbalancing angle. A few kids choked on their drink. Everyone looked the same. They were all in different hues of red, the majority of them still in their school uniform. Only, one kid stood out. He was taller than some, and shorter than many. He was skinny, looked like the kind of person that would be rather lanky once he grew some more. Then, she noticed what made him completely different than all the other kids in the party. He had stormy grey eyes and wore a headband, tied very tightly and securely around his head, obviously. It was a headband after all. This was about the time when she came to the realization that he was the exact same kid from earlier that day. He was the rebel kid at that school.

The kid stood in front of her now, but not up close. He looked slightly awestruck, but was mostly staring at her with a questioning glance. He was about her same height, as they were able to look eye to eye. For his gender, and the looks of his age, that wasn't very tall.

"Umm… Excuse me… But, do I know you?" His voice broke the silence in the cave. He did look relieved though, since he was looking at a girl, not the headmaster of the school.

"No, not really. I was just out for a walk, and, well, saw light and heard some music coming from this cave. I was just curious about what was going on in here." Katara replied she spoke clearly, not muffling a word, not missing a pause between the comma, and period. There was another thing Aang noticed her voice was absolutely beautiful.

"Oh, well… You could join the party if you want?" He sounded hesitant to invite the stranger, but she was just a girl, how harmful could she be? Says the 15 year old who is the most powerful person in the world, who's Sifu happens to be a 13-year-old girl that is the most powerful earthbender in the world. Aang thought to himself, a small, sarcastic small on his lips.

Katara bit back a rude response. Obviously she would want to join the party, why else would she come here? "That would be nice, thank you." She faked a pleased smile, prepping herself to spend the next few hours acting rather giddy.

"Great!" The boy said cheerfully, his eyes sparkling once more. His one word response seemed to trigger everyone to go back to what they were doing before Katara interrupted the party. They danced, the songs started up, and some girls began giggling in a corner.

Just as Katara was about to go mix in with the small crowd of rebellious school kids, she felt a light, airy, tap on the top of her shoulder. Her skin quivered. She wasn't used to being touched in a way of not being intentionally hurt. She turned slowly, to find the same boy standing behind her.

"I didn't get a chance to introduce myself." He said with a half smile, in a polite tone. Katara looked at him, staring at his eyes, awaiting his response. "I'm Kuzon, I'm new here… came from the earth kingdom colonies." His eye twitched a bit while he said it, and shortly after it, his eyes darted to the right for a split second. He was lying.

The first thing Katara learned when she became an assassin, was how to detect liars. Although some people are impossible to read, others are incredibly easy. The average person does about the same thing when they lie, although, some are a bit different. Most people blink, twitch, swallow, stutter, fidget, or sweat when they tell a lie. You can usually tell is someone is lying by having direct eye contact, which is what Katara does whenever she speaks with someone. It was one of her greater weapons.

"That's cool, I'm… Katara, from the heart of the Fire Nation." She gave off almost a sickly sweet smile.

"That's a nice name, but isn't that a water tribe name?" Aang remembered Sokka talking about his long lost sister, Katara.

"Yes, indeed it is. My parents were undercover spies in the Northern Tribe, my mother was pregnant for me then and so she had to name me a water tribe name to not raise suspicions, and when they came back from their job, I guess the name stuck when I was born." Katara was one of the people who mastered lying.

"Oh… Well, that's interesting. Anyway, would you join me for a dance?" Aang, or Kuzon, offered his hand to her, and waited for her acceptance of the invitation.

Katara was a bit puzzled on how this kid was so trusting to a total stranger. Soon as he got her name, he was offering a dance. Now what was she going to do? Should she accept? Should she stay on the safe side and decline? The safe side? Katara growled internally. She passed the safe side many years ago. Without thinking, she placed her hand in his. She regretted it when seconds after, Kuzon flung her out into the dance floor. He was careful while doing it, but he still nearly ripped her arm off from the unsuspected force. Spirits, for being so scrawny, he is pretty strong. Katara was pleasantly surprised.

The crowd of dancing kids slowly parted as they realized that the mysterious Kuzon was about to dance with a complete stranger. The tempo of the currently playing song sped up as it neared what must be the chorus, although it was an instrumental song. Now Katara was stuck. She didn't know how to dance. She was an assassin, not a dancer! Now here she was, expected to dance in front of a group of kids.

Aang looked at her, she looked slightly baffled. She didn't know what to do next. Aang then frantically began to think, did she know how to dance? Was she a bender? Did she know any kind of gymnastics, or something? Well, he wasn't going to find out by thinking the questions. So he leaned in, and asked, "Are you a bender?"

Katara froze. His question churned around her brain like poison. Are you a bender? Yes, she was. A master waterbender, bloodbender, and healer, but no Fire Nation citizen was any of these. So, she had to go against her own element.

"No. I am not."

"Okay then, do you know any form of martial art?" Aang sounded hopeful.

Katara inwardly smiled. She knew many kinds of martial arts. "Yes, I know many."

"Good! Then you should catch on quickly!"

Aang gave her know chance to ask what he meant by that, because next thing she knew, she was swung up in the air and he was cartwheeling backwards. She spun around and landed on her hands, and gracefully placed her feet down behind her, and then she popped up from her awkward position. The crowd awed at them both. Aang then walked around her in a circle, as if he was about to launch an attack on her. Katara complied, and after completing a few circles, creating suspense in the crowd, she grabbed his clothed arm, pushed it down, and together they cartwheeled to the side, side by side. Aang put his hands firmly on her waist and lifted her up, holding her above him; he twirled in a circle before gently setting her on the ground. The kids awed again. Katara caught on quickly, and soon the two were actually fighting, only, disguising it by a few little flares to make it look like a dance.

"Who does that girl think she is?" Jealously seeping into the voice of the girl.

"Onji, I'm sure Kuzon is just being nice. You know, being a good hostess of a party." Another girl reasoned.

"But look how beautiful she is! Kuzon is mine, not hers." Onji said distastefully. She didn't mean to sound like a greedy four-year-old, but Kuzon was the hit of the school ever since he first appeared at the small school. He instantly stole the hearts of many girls throughout all of his mysterious rebellious acts, and he was polite, and oh so charming.

"Onji, we know nothing about him. We shouldn't be calling dibs on him. He probably has a girlfriend from the colonies or something." Another girl added, slightly sad at the prospect of him being taken.

"Whatever, I just don't like this stranger girl. Sorry, I guess I've gotten touchy ever since Hide dumped me a few weeks ago." Onji sighed, and watched Kuzon dance with the girl.

Kuzon and Katara danced for several minutes, until a light sheen of sweat was on both of them. One thing Katara noticed was that while her breathing was slightly erratic, he was breathing completely normal normal. She pushed the fact aside as the bowed and walked away from the center of the dance floor. Kuzon motioned for her to follow him as he disappeared towards the back of the cave. Katara was hesitant, but did as he asked. She might as well be nice to him, he did dance with her.

At the end of the cave there was a few small earthen tables, another larger table holding a punch like drink, with a few little snacks. Most of the tables were empty though, since just about all the kids were busy dancing. But, there was one table that was occupied. It contained a small, female child who looked like she may have been twelve. Her shiny black hair was in a messy bun, and her overgrown bangs hung loosely over her face. Between the strands of hair covering her eyes, Katara could make out a cloudy green color. The girl's eyes were glazed over, staring in one spot particular, not focusing on any object. The girl was blind.

Next to the girl, was a tall man, or almost man. He was of dark skin, had dull blue eyes, a chiseled face, and his hair pulled into a ponytail. He looked liked he hadn't shaved in a few days, since he had dark pointy stubs around his face of what will soon become a beard. What stood out with him the most was that he looked familiar to Katara, and, he looked like he came from the water tribes. Katara bit down the thoughts of how much he looked like her brother. The young man had his arm draped over a young woman, who looked around 19, Katara's age. She had short, auburn colored hair, slightly pale skin, and dark green eyes. She was tall, muscled, and looked very athletic.

"Hey guys! I wanted to introduce you to Katara." Kuzon said happily, pointing towards the girl next to him. The blind girl looked directly at her with an unnerving stare, it chilled Katara's blood, blind people can't stare, but this one was. For the first time in her life, Katara felt endangered. Everyone in at the table was staring at her with a hostile glance. She was out numbered if anything happened, and there was nowhere to hide. Damn it, Katara! You are an elite assassin, why the hell are these nobodies scaring you like this? Katara growled to herself.

Sokka stared at her. I wanted to introduce you to Katara. Aang's words vibrated throughout his skull. What he saw before him was a spitting image of his mother. This had to be his sister. Katara, I've missed you.

"That's great Twinkletoes. But right now, we got a big problem." The blind girl had a girly voice, laden with a war-ruined personality it seemed like. Before Katara could ponder more, the music stopped abruptly, everyone froze, some even hid under their tunics. There in the opening of the cave, was the headmaster from the school.

"What is going on in here?" He said angrily. No one answered him. They were frozen with fear.

Kuzon quickly left his group of friends and went towards the headmaster, so an innocent school kid won't get blamed for the party.

"You!" The headmaster growled, when he saw Kuzon approaching him, sullenly. "Get him!" The two women from the reform school chased after Kuzon, attempting to grab him.

Aang was stuck. He couldn't use airbending to enhance his movements, not in this environment. He couldn't bend any element, but fire, and if he firebended, he risked accidentally hurting someone, or worse, burning his headband off. A few kids quickly tied their sashes around their head in a similar fashion to Kuzon, trying to help him out, but the one lady behind him caught up quickly, and grabbed the end of Aang's headband, pulling the knot loose. The headband fluttered away. In a mere second, Kuzon was on the ground, his head tucked safely away in his arms. Not one person could see his blue tattoo, or else everything would be ruined.

Soon as Aang fell to the ground, trying to protect his forehead from being seen, his group of friends where instantly there, protecting him. Katara smiled evilly. He was hiding something big, she guessed right about him.

"You will leave us alone if you knew what was good for you." The dark skinned one threatened.

"Out of my way." The lady attempted to push the large teen aside. He grabbed her arm, and pinned it forcefully behind her back. She twisted around, managed to get free, and aimed a punch at the teen, but it was counter blocked by him grabbing her wrist and punching back with his other arm. She barely dodged it, and next thing she knew, he did a roundabout kick towards her legs.

Whilst this was all happening, the tall girl grabbed Kuzon's headband, and gave it to him. He tied it on quickly, jumped up, and touched Sokka's shoulder, letting him know that he didn't have to cover for him anymore. Sokka stopped fighting, and backed away. He purposely did not hurt the lady, but he did a good job of distracting her.

"I would love to stay and chat, but I gotta go!" Kuzon said with a sly smile, back flipped away from the lady as she tried to grab his headband again, and made a run for the door with the rest of his buddies, except for one. The dark skinned one gave Katara a look, grabbed her arm, and pulled her along with them. Sokka wasn't going to loose his sister again.

Katara resisted his pull, but he gave her a scolding look and tightened his grip. He was too strong. No matter how much conditioning and training Katara had, a girl was naturally weaker than a man. She could escape later, but maybe it was for the best if she were with the group, it would allow her to discover their secret. She had a strong feeling that this was the group she was looking for.

Kuzon ran behind the rest of his buddies, making sure everyone of them made it through. As they entered a dark hole in the very back of the cave, and as Aang got near it, he jumped in the air, swiped his hands below him, and in response a rock wall closed up the gap, separating them from the rest of the party. Katara's eyes narrowed.

Then they stopped running. "I can't see anything!" The one who was clutching her arm complained.

"Oh no! What a nightmare!" The voice of the blind girl growled sarcastically. Then, she paused. "What's she doing here?"

"I couldn't just leave her!" The dark skinned guy let go of her arm, his voice rising.

"Yes, you could! Sokka, you just endangered his life by doing so!" The blind girl pointed towards Kuzon. Katara didn't hear the rest of his statement. Her blood froze. Sokka.

Sokka looked at his sister, her eyes wide, staring at him, mouth agape.

"Katara…" and he pulled her into a tight hug.

Everyone else stared at them strangely.

"Umm… Did I miss something?" The tall girl asked, confused.

Sokka pulled away from the hug. "Everyone, this is Katara, my sister."

"Snoozles has a sister!" Toph spluttered, feeling the vibrations of the new girl.

"Sokka, what are you doing in the Fire Nation?" Katara asked, smiling. She was so lost up in her reunion that she forgot about her job.

"Well, we are all, um-" he looked towards Aang, and Aang nodded in approval. "We are helping Aang master the elements. He needs to learn firebending, and, well, since everyone thinks he is dead, we decided to use that to our advantage and lay low. But Aang accidentally got mistaken for a student at this school in his disguise, so he just played along with it." Sokka gave off a shrug.

"Well, Katara, as you know, that is Sokka, this is Toph-" he then stopped. They were in a pitch-black cave. Why introduce her to people she can't see? "I'll introduce you to everyone when we get out of the cave… But in the group we got Sokka, Toph, Suki, and me." Aang said. Then he tapped his foot on the ground, feeling the vibrations of his surrounding, and punched at the cave's wall, taking a short cut root right through the cave, instead of taking the dark path ahead of them. Toph chimed in, and together they earthbended out of the cave.

All the while, Katara was silent. She walked numbly, but no one noticed. She danced with the Avatar. She just danced with her prey. She smirked. She was right where she wanted to be. The Avatar was in her clutches, and he trusted her. Her assassin personality came back. The prince was paying her an enormous sum of gold, and soon, it was going to be hers.

She was Sokka's sister. The Avatar won't suspect a thing. If he does, he'll be far to late to save himself.
