A/N I'd like to dedicate this chapter to discontinued-evil8 for being the first to review this story and be my first review ever. P.S. Yay second chappie!

"Now today, you'll be working on your project for the science fair. Just a reminder for when you work on this, it's worth 60 of your gra–"

Mr. Delmas's walked in the room with a girl, Xenon. "Excuse me Mrs. Hertz for interrupting, but I'd like to introduce our newest student. This is Xenon Smith. She comes to us from Paris and I'd just like to welcome her here to Kadic." Mr. Delmas left leaving Xenon in front of the class shifting her purple messenger backpack on her shoulder. Xenon was wondering how the gang was going to react to her. Well, I have to do a better job this time around. Xenon thought. "Well, Miss Smith. You may sit behind Mr. Della Robbia. Mr. Della Robbia would you please raise your hand." Mrs. Hertz said. Odd did what he was told. Xenon sat down behind Odd. The gang immediately turned around and wanted to ask her questions.

"Gosh, Odd. Can't go ten seconds with out asking the new girl out?" Sissi hissed from a seat that was close to them. Before Odd could say a comeback, Mrs. Hertz interrupted them.

"Please, pay attention." She said angrily. The gang faced the front. "Now you may not care that you're science project in worth sixty percent of you're grade, but some do. If you fail to turn it in on time, I will not accept it. Which, in turn, means you fail this class for this semester and I will not let you make it up." Mrs. Hertz continued going on about the science project for a half an hour. Everyone got bored, even Aelita and Jeremie who was waiting for the class to end. So, they could ask Xenon some questions. Xenon had taken out a piece of paper and started to draw.

Once Mrs. Hertz saw no one was listening which they all had twenty nine minutes ago. "You may pick your partners. No more than three. You may also start discussing ideas of what to do. The project is due in five weeks." As soon as she stopped talking, the students went to their friends and started. The gang circled around Xenon.

"Can we ask you some things?" Jeremie asked.

"How about after science?" Xenon offered.

"Well, well, well." Sissi said as she walked over to them. "Xenon, let me give you advice: stay away from these losers." She motioned at Jeremie, Aelita, Odd, and Ulrich. The gang scowled at Sissi.

"Sissi, can ask you a question?" Xenon asked. She didn't wait for an answer and continued. "Why do you have to be a bitch? That is why you've never had a true friend or boyfriend. Why do you think people won't go out with you?" Xenon motioned at Ulrich. "Do us a favor and leave us the hell alone and fuck off." Sissi was shocked. No one ever talked to her that way because she was the principal's daughter. Sissi walked over to Herb and Nicholas. Xenon turned back to the gang, being satisfied, and smiled. The gang looked shocked too.

"I've been wanting to tell her that for years." Odd said, giving Xenon a high five.

"Yeah," Ulrich agreed.

"So, how do you want to split up?" Aelita asked.

"Well, Aelita and myself can be together and Odd and Ulrich. Xenon you can pick who you want to be with. But FYI Aelita and me won't need much help." Jeremie said.

"Hey, what's that suppose to mean, Einstein?" Odd said sounding offended.

"Well, you two are always last minute." Jeremie simply stated.

"Eh…" Odd said.

"I'll be will Odd and Ulrich. Sounds like they'll need the help they can get." Xenon said. She opened her backpack and got out a laptop. It was metallic looking.

"What model is that?" Jeremie asked never seeing anything like it.

"I made it--"Xenon started to say.

"Oh great an Einsteinette." Ulrich said. Xenon ignored him.

"It can hold 600 GB." Xenon continued. She flipped the top open to reveal a keyboard. It had all the regular keys, but they were about fifteen that looked like they were written in a different language. Xenon pressed the power bottom and within five seconds she was at her desktop.

"How did you make a computer that can hold that much?" Jeremie asked out of curiosity. Odd's eyes narrowed slightly. Jeremie liked Aelita but that mean he could shift his eyes to Xenon. Odd wanted to date Xenon.

"I just hooked up a bunch of memory cards and also expanding them passed their labeled memory space." Xenon said. "Not very hard." Odd liked Xenon even better. At least she explained computers where it actually made since…the first time.

"But how? Could you go into detail?" Jeremie asked, wishing he had a laptop that could hold that much.

"The truth is I don't know exactly." Xenon said. "I just screw with the computer till it does what I want." Jeremie looked disappointed. He turned to Aelita to discuss the project. Aelita was a little suspicious.

"Why would you need that much memory?" Aelita asked.

"Uh…" Xenon said wondering if she should say. I'll have to tell them eventually. Just maybe not right now. "I'll tell you once we can get away from everyone else." Xenon turned to Odd and Ulrich to discuss their project and so did Aelita and Jeremie.

The bell rang for lunch, which was an hour long. Odd and Ulrich agreed with Xenon on a project where you built some sort of train which could levitate and move using magnets. Xenon assured them it was elementary. Ulrich said, 'To what? Finding an alternate energy resource?' Jeremie and Aelita were going to work on a robot that would have artificial intelligence.

They walked out of the science building to the bench that the gang always hung out at. Yumi was already waiting.

"Answers?" Yumi asked as they approached.

"I'll tell you most of my story." Xenon said.

"Most of?" Odd asked.

"There are some things I can't tell you." Xenon said.

"Why?" Aelita asked.

"Look we're wasting time here. Ask away. I'll tell you what I can't answer." Xenon said.

"Who are you?" Jeremie asked.

"Xenon Smith. Xenon sounds a lot like Xana. But considering my father knew Franz Hopper. It wasn't a surprise."

"Who was your father?" Aelita asked.

"I can't…" Xenon said looking at Aelita. I should tell her. I mean she is my… Xenon sighed. "My father was technically…" Xenon sighed again. "Franz Hopper."

"What?" Everyone, besides Aelita, said.

"You're my sister?" Aelita asked, not seeing any resemblance. If they were crayons, Aelita was a pink while Xenon was purple.

"Yeah."

"How?" Aelita asked, still not seeing any resemblance, but she believed Xenon. It was a sister thing. "Why don't I remember you?" The gang besides Aelita decided if Xenon was Aelita's sister it would be best not to interrupt.

"I wasn't always apart of your life. Actually, I was in your life very little." Xenon sighed. I know I have to tell her. But if they ask how I know this. I can't tell them the real reason. I mean I found out by… "Franz Hopper created me. I mean not the birds and the bees way, but… Before Franz Hopper got into Artificial intelligence. He was a science teacher, here at Kadic, who was interested in genetics. He had started to mess around with them. He gave me intelligence, blonde hair, purple eyes, and a mixture of other things. When mom, Raisa," Xenon smiled at mention of Raisa. "Was pregnant with you. Franz Hopper thought to try if I'd work. I did." Aelita thought on this. Her eyes widened in shock.

"You're my twin sister?" Aelita asked.

"Yep." Xenon said casually. Aelita hugged her long-lost sister.

"How come you weren't in Aelita's life long?" Yumi asked calmly not wanting to ruin Aelita's happy moment but still wanted to know. Aelita released her hug.

"Franz fell into depression. He forgot genetics and got into making Lyoko. He thought it was best if one daughter of his was safe kept somewhere with some of the keys. Raisa, mom, wouldn't let Aelita be the one since she wasn't a project. She loved me but Aelita was actually her daughter. So, I was put into the Smith family in Paris when I was six months old." Xenon said a little bitterly. The group was quiet.

"I'm so sorry." Aelita said, who looked like she was about to cry.

"It's alright. I never really had real parents. I mean Franz Hopper created me and Raisa only gave birth to me." Xenon said. "Any more questions?"

"How did you find out about Lyoko?" Jeremie asked.

"Well, you know when Aelita was thirteen. Franz and Aelita were running away from the government to Lyoko. Before he went on Lyoko he sent a message to me which he wrote when I was six months old, about the time I went to the Smith's, with all the info on what I had to do with Lyoko. He had updated the message as he worked on Lyoko. As you know not long after he got on there, Xana took Franz Hopper." Xenon stopped. Should I even say it? Xenon sighed. "I took myself to find the factory. For the next ten years, I took care of Aelita."

"Wait a minute." Ulrich said. He didn't catch what I said, did he? Xenon thought. "I never actually thought about it. You don't age in Lyoko. Aelita's--"

"Twenty-six. Yes." Xenon said.

"So, you're both twenty-six?" Odd asked a little turned off that he wanted to date a twenty-six year old.

Xenon sighed. I should correct them, but I can't tell them…but I shouldn't lie… Xenon figured she answer in another language that she knew. "Iie…" Everyone except one knew what iie meant.

"Yumi, isn't that Japanese?" Ulrich asked.

"Yeah," Yumi thought for a second of what it meant. Over the years she was accustomed to French. She still remembered Japanese but it took her a couple seconds. "No? What do you mean no?"

"I can't tell you. I'm sorry. I promised myself not to tell. I can't. I'm sorry." Xenon said as she stared at the ground.

"Why did you leave Aelita alone on Lyoko?" Jeremie asked. He wouldn't have done that. "After ten years, why did you leave?" Jeremie's voice had anger in it. Xana could have killed Aelita.

"I had to go back to the Smith's. I had promised them." Xenon said still looking at the ground. It's half true… Xenon thought to herself.

"Jeremie, relax." Aelita said. "If she hadn't left, I wouldn't have met you." Jeremie blushed as he got what she said.

"Why did you come back?" Odd asked. He was glad she came back, then he would have a chance with her.

"I felt it was necessary and I wanted to see my sister." Xenon replied as she looked up.

"How did you know our names?" Ulrich asked.

"You don't think I'd leave my sister to complete strangers would you?" Xenon asked them. "I checked all of you out completely. I know some things that even others don't know." She stared at each of them, but stared longer at Odd than anyone else. Odd knew what she was talking about and looked away from her piercing gaze. A silence fell upon them. They wondered how much Xenon knew about their pasts.

Xenon's story checked out with all of them, but Aelita still had one more question. "How do you know all the information, like the stuff before we were born?"

Xenon smiled. "I can't tell you that."

A/N Where to start? Hm… with Xenon's insult to Sissi. It's there for a couple reasons. One, I dislike Sissi and have always wanted to say that to her. Two, she deserves someone to say it to her. Three, I'm doing a favor for the gang. Four, it's my fanfic and I can do anything! Muahahaha :D Oh and the science experiment the Xenon's and co are doing is an actually experiment I found on the Internet, which might not be reliable but anyway... If you look carefully you can find, about three times, where I give a future plot point. I kept on mentioning it. But did you catch it? Or maybe it was the wrong future point. Ooops! There's at least three future plot points mentioned in here…Review!
