Disclaimer: I do not in any way own Avatar, unfortunately. Nick has that pleasure. I only own Xantara and Blaise.

A/N: Okay, first off, I have no idea if this would at all (the idea that one could go into the past) be possible in the world of Avatar: The Last Airbender but I'm going to make it possible in my story. In here, it will focus mostly on four characters. It will be, obviously, Zuko, Katara, then Xantara, and Blaise. And just so you know, you say Xantara like Katara but instead of the Ka you say San…I think. In this there's the prologue and chapter one (you can tell where chapter one starts because it's bolded, italicized, and underlined.) Enjoy! By the way, a huge thanks to my beta reader: kyoshilover at the Distant Horizon forums!

Child's Play

Prologue Blast to the Past

"I'm right and you're wrong!" yelled a girl no older than six.

"You're not right! I'm the one who's right! That's why Mommy and Daddy love me better!" Shot back the boy who happened to be the girl's twin.

"No they don't!" the young girl's voice started to falter as tears welded up in her eyes.

"It's true and they loved me longer."

"That's not true!" the girl was now in tears.

"Yeah huh. I was born first so Mommy and Daddy have had to love me longer." The boy replied smugly.

"You're lying Blaise!" The girl accused, pointing a finger at her older brother.

"I'm not lying, Xantara. If there is anyone who is lying, it's you."

Xantara looked up at her brother confused. "How could I be lying? I know when I'm telling the truth and I am now."

"Well, it's not so much that you are telling lies, it's much more that you are living a lie." Blaise explained.

"That's not possible and 'sides that doesn't even make any sense,"

"Yeah it does Xantara, it's just that you're little brain can't understand it." Blaise insulted a bit too harshly.

"Well…I don't care if I can't understand what you say. I know that Mommy and Daddy never hated each other!" Xantara stood with her hands on her hips.

"Yeah they did, Daddy told me. And you wouldn't call Daddy a liar would you 'Tara?"

The six-year-old fumed. "Don't call me 'Tara! And Mommy said that she never hated Daddy!"

"Mommy's just saying that because poor little 'Tara can't handle the truth." That was the last straw for the young girl.

The girl gave a scream and pounced on her brother. The two wrestled down the hill that lead to the gazebo in the middle of their mother's garden. Yelps and war cries could be heard throughout the palace's property as Blaise yanked at his sister's hair while Xantara retaliated by kicking him all over the place. The twins were too preoccupied with trying to beat the other that they didn't hear the cries and screams of their parents.

When they got to the steps of the gazebo, still arguing, Xantara pushed Blaise up the steps to corner him. Blaise pushed his sister back once she was up the small set of stairs and she backed up to the rail of the gazebo. With both arms outstretched, the twins placed their hands on the other's shoulders and fought until Xantara collided with the symbol of the Water Tribe and Blaise onto the Fire Nation's emblem. Both insignias glowed with their respective colors when the two children locked eyes with their parents. Just with that glance, Xantara and Blaise disappeared on the spot.

They could faintly hear the cry of their mother while Blaise and Xantara clung to each other. It seemed like they were traveling in a vortex that swirled with the colors of the four nations: a sky blue which was almost white, a rich forest green, a fire red, and a deep navy blue. The velocity that the twins traveled at forced the two apart as they yelled the other's name.

They both landed with a thud on the ground. Xantara brought her hands up to her head to make the swirling stop while Blaise shut his eyes and placed his hands on the metal ground. Once both of the twins got oriented, they looked around. Xantara let out a cry that sounded like "Blaise" while Blaise did the same except using his sister's name.

Xantara looked around wildly around her as she scanned the area. Her brother was nowhere to be seen.

Chapter One Fainting Benders and Disbelieving Parents

"Come on Blaise! This isn't funny! Where are you? Blaise!" the young girl had tears trailing down her cheeks.

With her head held in her hands, she sat down and cried uncontrollably. Xantara couldn't hear the pounding of feet over her cries. It wasn't until she felt a cool hand touch her shoulder that she noticed…well, everything around her. Xantara lifted her cool blue eyes and saw a girl before her. Without another thought, Xantara threw her arms around the girl and hugged her tightly, still sobbing.

"Umm…" The girl trailed off.

"Where's Blaise?" Xantara asked in a whisper. "He thinks it's a joke, doesn't he? But he really scared me, where is he?" Xantara pulled back from her embrace to look at the girl she was hugging.

"Umm, who's Blaise?" Xantara spun around and jumped off the girl and almost tackled the boy who spoke.

"You know who Blaise is, Aang!"

"How do you know my name?" Aang questioned awkwardly as he placed his arms around the six-year-old.

"Blaise put you up to this, didn't he Uncle Aang?"

"Uncle?" Xantara looked behind her and did the same thing she had done to the young Airbender.

"Of course you'd play along with this, Uncle Sokka!" Xantara looked behind Aang when she heard soft steps. "There you are Auntie Toph!" Xantara ran up to the twelve-year-old girl and hugged her legs but returned to where she stood before. "But you know what?" Xantara now stood on the ground with her hands on her hips and looked at the trio. "You all look younger. And where's Daddy? Wait…he's probably yelling at Blaise for scaring me. Where are we? This isn't the gazebo."

"What are you talking about?" Katara questioned as she looked at the girl curiously. "Who is Blaise? And why are you calling Aang and Sokka Uncle and Toph Auntie? You don't even know them and who is Daddy?"

"Are you feeling okay?" Xantara walked up to the young Waterbender and pressed her palm on her forehead. "You don't have a fever, Mommy."

"MOMMY?" The four of them shrieked.

"Yeah, you," she pointed to Sokka. "Are my Uncle Sokka. And Aang," she looked at the stunned twelve-year-old. "Well, you're not really my uncle but that's what I call you. The same is with Toph, not my aunt but since you're with Aang then that's why I call you Auntie," Toph, Sokka, Katara, and Aang's eyes all widened at this declaration. "And this is my mommy. You guys know that." She looked Katara in the eye. "You sure you're okay Mommy? You look really pale."

"You must be mistaken," Katara started as she stared at the girl and waved her hands frantically. "I can't be your mommy."

"Yes, you are! Why do you have to listen to Blaise? I don't play this game anymore!" Xantara started to get teary.

"Who is Blaise? And trust me; I'm not your 'mommy'. I'm only fourteen!"

"You can't be fourteen! You must have taken something to make you look like your fourteen. And it's all because Blaise wanted to trick me! And where's Daddy? Mommy! Tell me where Daddy is!" Xantara demanded as she shook her 'mother' who was still in shock.

"Listen little girl," Aang started slowly as the young girl turned to look at him with tears in her eyes. "We have no idea what you're talking about. Sokka and I can't be you uncles. I don't even…like…Toph that way, and Katara can't be your mother. We don't know who your daddy is and we don't know who Blaise is either."

Xantara narrowed her eyes. "You're not lying to me, are you?"

"Why would I lie to you?" Aang bent down to her height and looked her in the eye.

"Because…" Xantara looked down at the dirt and kicked her foot. "Because, Blaise said I was either lying or I was living a lie. Which I have no idea what he means by that."

"First of all," everyone turned to Katara. "Who is Blaise?"

"Your son, Mommy. My twin brother, well…according to him, he's my older brother. He said that you told him he was five minutes older than me." Xantara answered still confused by her mother's questioning. "Of course you should know all this. All of you should."

"How old are you?"

"I'm six! I'm turning seven in…a month!" She held up six fingers to show Toph, who stood behind Aang.

"Katara? Is there something you haven't been telling me?" Katara looked up to Sokka.

"No, Sokka. You really think that I would have a six-year-old when I'm fourteen?"

Xantara interrupted before Sokka could even open his mouth. "But you're not fourteen Mommy. You're turning…umm…Daddy told me…oh yeah! You are turning twenty-three in a month! You always said Blaise and I were the best gift you were ever given, it's true, isn't it?"

Katara was still sitting down from the shock and had wide eyes but Toph answered for her. "You see, technically, if what you're saying is true, then you won't be born for another…"

"Year and a half," Aang answered for her.

"But what I'm saying is true!" Xantara jumped in frustration. "I'm not a liar!" Once again the girl got tears in her eyes.

"Look, umm…what's your name?" Aang questioned rapidly.

"Xantara," She answered cautiously.

"Xantara, beautiful name, by the way," The girl replied with a thank you and beamed. "You haven't been born yet. Katara's still fourteen. If my calculations are correct, then Katara had you when she was sixteen—"

"SIXTEEN?" Sokka shouted.

"Shut up, Sokka!" Katara hissed as she looked up at her brother as he just glared at her.

"Anyway, the most reasonable explanation for you being here is that…" Aang's voice trailed off.

Toph finished his sentence for him. "You somehow got transported into the past,"

"That would explain why Blaise and I were in the swirly-tube thing!"

"Swirly-tube thing?"

"Yeah, Mommy!" Xantara walked up to Katara and sat on her lap. "Don't get mad, but Blaise and I were fighting again then he said something and I jumped on him and we wrestled our way down the hill to your gazebo."

"What happened after that?" Toph asked interested as she took a seat next to Aang. Sokka reluctantly sat down as well.

"Well, I…umm…pushed him up the steps and once I got up he pushed me back. So, then we both tried to attack the other but he pushed me against the Water Tribe's symbol and so I pushed him against the Fire Nation's symbol. I heard you and Daddy screaming, Mommy, so we both turned to look at you and Daddy." She took a breath before continuing dramatically. "Then I saw a great, shiny blue light and I heard you scream as Blaise and I were pulled into the swirly-tube thing. I tried to hold on to Blaise but I couldn't, so when I let go, I ended up here. Where is here anyway?" Xantara explained.

"This is part of the Earth Kingdom's land. The thing I don't get is why you ended up here?" Aang questioned more to himself than everyone else.

"So…I really am your…Mom?" Katara whispered the last word.

"Uh huh. But since you didn't know who I was that might explain…" Xantara trailed off due to a small shake.

It turned out that Katara had fainted.

Change of Scene

Blaise opened his eyes and rubbed them just in case. His surroundings were still the same as they were when he first glanced around. There were men and mental all over the place. It's a ship! Blaise concluded. The men were staring wide-eyed at the boy and one had pushed the other, who ran off. Blaise stood up and looked around, eyeing each of the men. Suddenly Blaise yelled out.

"'Tara! Where are you? Come out 'Tara! I promise I won't hurt you!" Blaise looked around but he didn't see his twin anywhere.

"Who is yelling?" Blaise spun around and ran.

Blaise had run into the arms of an unsuspecting young man who just kept his arms at his side. Blaise had wrapped his arms around the man's neck and his legs were around his waist, holding on for dear life.

"Why aren't you hugging me?" Blaise pulled back after a minute when he hadn't felt arms around him.

"Why would I hug you?" The man questioned with disgust in his voice.

"Zuko, who is he?" A plump man asked pointing to the young boy who had his arms wrapped around Zuko.

"Uncle Iroh!" Blaise jumped down from Zuko and ran to the retired general.

"How does he know your name, Uncle?" Zuko's eyes were narrowed as Blaise hugged the old man.

"Because he's your uncle, duh!" Blaise replied with a know-it-all tone but immediately spoke. "I am so sorry! I didn't mean to say that! I'm so sorry! Please don't punish me!"

"What are you talking about?" Iroh looked at the young boy quizzically.

"I'm going to get in trouble! I'm not supposed to act like that! Daddy won't let me! I don't want to get punished like last time!" The boy explained with tears in his eyes as he hugged the old man tighter who just hugged the boy in return.

"What happened last time?" One of the crew men asked but quickly shut up after Zuko sent him a look.

"I had to stay in my room for two days! The only people I was allowed to see where Mommy and Daddy. They either just gave me food or went to give me…a...lecture." Blaise eyes were wide disgust and nodded his head when he finished.

Iroh chuckled at the boy and proceeded to ask the boy a question. "Where's your daddy?"

Blaise's eyebrows were furrowed in confusion. "Daddy's right there," He pointed at the wide-eyed sixteen-year-old Fire Prince.

"You must be mistaken—" Zuko started.

"No I'm not. I'm always right, even ask 'Tara. Where is 'Tara anyway?" Blaise looked around him.

"Who's 'Tara'?" Iroh questioned.

"Her names Xantara but I call her 'Tara because it bugs her lots. Mommy and Daddy tell me not to call her that but I still do,"

"But who is this…Xantara?" Zuko questioned.

"Daddy? You should know…well, I suspect you know that she's your daughter, if not then that's just weird."

"I don't have a daughter and I'm not your 'daddy', okay? I have no idea who you are or what your name is!" Zuko explained.

"Mommy says you can be thick but…" the young boy's voice trailed off as he looked at his father.

"Clearly this boy is delirious!" Zuko stated.

With eyebrows scrunched up Blaise asked "What's delirious?"

"He means you're hallucinating." Iroh answered absentmindedly as he watched his nephew pace.

"Okay…" Blaise's voice trailed off.

Zuko suddenly stopped pacing and walked up to Iroh who still was hugging the boy. "I'm not your father and I don't have a daughter."

"You always said that lying wasn't good," the boy pointed out.

"I'm not lying!" Zuko's eyes flared and smoked steamed out of his fists.

Blaise yelped and hugged Iroh closer. "Now, Zuko, calm down. Let's all sit down and have a nice cup of tea."

"I don't want tea!" Blaise and Zuko responded in unison.

The two looked at each other. "Wait a minute…wait just one minute."

"What?" Zuko's eyes narrowed as did Blaise's.

"How old are you, if you don't mind me asking?"

"Sixteen, why?" Suddenly Blaise gasped.

"You can't be sixteen! Or can you? It would explain how you don't recognize me or know who Xantara is." The boy said more to himself.

"I say tea would be appropriate at this time." Iroh didn't wait for an answer and started walking to his room. Blaise was put down and followed as did Zuko.

Once they were situated, Zuko started talking. "What were you talking about earlier?" Zuko's voice was softened though he didn't know why.

"Like what?"

"Why are you calling me daddy, first off?" Zuko asked.

"Because you are!" Blaise replied cheerfully.

Iroh cut in before Zuko could after he took a sip of tea. "How is Zuko your father?" Blaise narrowed his eyes and both Zuko and Iroh blushed.

"We know how I would be your father, but he meant why do you think I'm your father?" Zuko responded.

"Because you are, it's that simple!" Blaise replied exasperatingly.

"How old are you?" Iroh asked.

"Six! I'm turning seven in a month!" Blaise responded proudly.

"You would have had to be around nine, Zuko,"

"But that's not possible!"

"I know! What's your name Boy?" Iroh asked as he set down his cup.

"Blaise,"

Iroh then asked. "How old are your parents last time you checked?"

"Daddy was twenty-four and Mommy's turning twenty-three in month as well. My birthday is her birthday as well." Blaise explained.

"But I'm not twenty-four!"

"Zuko, the only way to explain something like this is for him to be…"

"To be what?" Zuko, once again, narrowed his eyes.

"He has to be from the…future."

Blaise spoke up. "Probably explains everything. I wonder how 'Tara's doing?"

"'Tara's your sister right?" Zuko questioned as he glared at the tea his uncle was trying to hand him.

"Yep! My twin sister! But I'm older than her. Do you know where she is?"

"My guess would probably be, seeing how you ended up with Zuko, who you claim as your father, you sister probably ended up with your mother. It's just a guess but it seems most logical." Iroh answered as he drank his tea.

"How did you end up in the past if you really are from the future?"

"I'm not exactly sure but before that happened Xantara and I were fighting again. So then she attacked me and we wrestled our way down the big hill in the courtyard all the way to Mommy's garden. When we ended up at the steps of gazebo, she pushed me. So when she got up the steps I pushed her back. Then we both went to push each other, and I made her bump into the Water Tribe's symbol and she bumped me into the Fire Nation's. I heard you and Mommy screaming, so we both turned around then out of the corner of my eye I saw a bright, like really bright, red light. I blinked then I saw a tub that swirled with colors and I couldn't hold onto 'Tara so I let go and that's how I ended up here!"

"What symbols did you two bump each other into again?" Zuko questioned suspiciously.

"The Fire Nations—"

"Yes, now Zuko—"Iroh cut in.

"And—"

"And it's time you go meditate Zuko, I have to speak with…Blaise was it?" Iroh said rapidly.

"Yep!"

"Now go Zuko!" Iroh ushered his confused nephew out the door as quickly as possible.

"Why didn't you let me tell Daddy the other symbol?" Blaise questioned once the doors were shut.

"Because, if what I have gathered is true, then Zuko will not like that he is going to marry a Water Tribe girl." Iroh answered as he sat back down.

"But he loves Mommy. It's a miracle if they're not together."

"Yes, but that will be in the future. As for right now, there is only one Water Tribe girl Zuko knows,"

"Who is that?" Blaise questioned innocently.

"The Waterbender who travels with the Avatar,"

"Oh! Katara, right?" There was a twinkle in Blaise's eyes.

"I think so," Iroh answered slowly.

"Yep! Mommy told me and 'Tara 'bout her trips with Uncle Aang, Uncle Sokka, and Auntie Toph and how sometimes Daddy wouldn't be the nicest guy around."

"You mean to say your mother, my nephew's future wife, is the one traveling with the Avatar?" questioned a wide-eyed Iroh.

"Uh huh!" Blaise took another sip of his tea as Iroh chuckled.

"Zuko's going to get a kick out of this!" Iroh went back to his tea and didn't hear a heavy thud outside the door.

A/N: Well, finally, the first chapter is done. The prologue alone just seemed to short so I added in chapter one. Xantara is like her mother; well, at six she's more sensitive since she has a brother who is almost exactly like her father when he was sixteen. If they seem a bit OOC then I'm really sorry. I'll try to get them into character. Remember to review! If I get no reviews then I'll just forget about the story. Hoped you liked it! And just so you know, this is the first Avatar story I have ever made. The stories I have written before are in the Harry Potter fandom so yeah, I may be a bit off and if I am, just tell me.
