Xenon opened her eyes and blinked twice. She didn't particularly like return to the pasts. Whenever she was returned to a time before, she had the sensation of falling. Xenon shook the feeling off and immediately thought about the day. It was earlier in the in the day, but it felt like weeks had past. So much had happened. Mr. Delmas found out that that Odd had been sneaking out of school to see Sissi. Mr. Delmas had punched Odd. Sissi had told Odd something that Xenon did not know about. Xana had attacked Aelita and Ulrich who, later she learned, were alright for the most part. Aelita and Yumi had gone to Lyoko to find out what Xana had been doing and deactivate a tower, if he even activated a tower. Xana had found Xenon and Odd on the highway and crushed cars in his way. He brought Sissi to them and broke her neck. Then the frantic rush to tell Jeremie to do a return to the past which he had done. But the question was, had they saved Sissi before she died?

As Xenon processed the information, she actually looked to see where she was. It was earlier in the day. She was in her dorm room in front of her laptop. Xenon turned her head and looked at her bed. Odd was there with a blank piece of paper and a pencil. Odd sighed in relief at being in the past, but then remembered there was a chance that Sissi had died before the return to the past.

"Xenon, is Sissi--" Odd asked slowly.

"On it." Xenon interrupted. She typed furiously on her laptop. Xenon had experience in this kind of hacking. It wasn't particularly difficult. It was easy to get phone numbers and addresses. She quickly sorted through the information. She found Sissi cellphone. She opened a calling application on her computer and dialed the number. Odd now stood just behind Xenon and watched her. Xenon turned up her volume as she and Odd listened to the ringing.

"Daddy..." Sissi complained slowly. Her father, Mr. Delmas, was sitting next to her on the couch at Eleanor's house in Paris. She had went to see her doctor for the regular check up on the baby. Her doctor had told her it was early enough to tell if it was a boy and girl. Sissi had taken her doctor's offer to see the gender of the baby and she had found out that she and Odd were going to have a girl.

"Elisabeth, I'm tired of asking--"

"Well, then stop asking it." Sissi said bluntly. Her father looked at Sissi rather angrily and almost glared at his stubborn daughter.

"Elisabeth--" Mr. Delmas sighed.

"It's Sissi." Sissi muttered under her breath.

"I want to know. I need to know who the father is." Mr. Delmas told his daughter.

"Daddy--" Sissi stopped talking as her cellphone rang. She took it out and looked at the number. She didn't recognize it, but answered anyway. She'd rather talk to anyone but her father. She got up away from her father and put her phone next to her ear. "Hello?"

Xenon and Odd sighed in relief as they heard Sissi. Xenon was going to hung up on Sissi as Xenon didn't have a microphone because she only wanted to know if Sissi was alive.

"Who is it?" A voice asked which they recognized as the questioning voice of their principal, Sissi's father. Xenon gave Odd a worried glance, remembering all too well of the events that had happened in a possible future.

"No one." Sissi responded quickly. "Hello? Anyone there?"

"It's a wrong number." Mr. Delmas' voice said.

"Yep." Sissi agreed, hanging up on Xenon and Odd.

Xenon and Odd sighed in relief. Sissi was alright and hadn't died before the return to the past. If she had, it could not be undone. She would have simply been wiped from existence.

"So, she's alright." Xenon stated after a very moments of silence. She hadn't known what to say and she loathed silence after an event. It just sounded unnatural to comment on the event.

"Yeah." Odd said softly. He stared at a blank, white wall as if it was the most interesting thing in the world.

"Whatcha thinkin'?" Xenon said, in English with a heavy, stereotyped, American voice.

"Something weird." Odd said with a weak chuckle.

"Which would be?" Xenon ventured.

Odd took a deep breath and let it out. He smiled as he said, "Just thinking of girl names. Since I know that it's a girl."

Xenon blinked. Is this what Sissi told Odd? Xenon thought. "Oh." Xenon said. How am I suppose to respond to that? Xenon thought.

"Sorry." Odd said, looking back at Xenon who had turned back to her laptop. "It's weird. I don't know how to take life anymore. I feel so changed."

"In what way?" Xenon asked, turning her attention back to Odd.

"I don't tell as much jokes anymore. I can survive without eating a meal." Odd listed.

Xenon rolled her eyes playfully and sighed. "Wow, big problems."

Odd shook his head. "Well I mean everything from Lyoko, Sissi and the baby, Xana picking on us, and everything. I just don't feel the same."

"Me too." Xenon agreed. Suddenly wanting contact with Odd, Xenon wrapped her arms around Odd's neck and pulled her head close to his chest. Odd wrapped his out arms around Xenon and rested his head on hers. Odd kissed the top of Xenon's head. "I—I..." Xenon paused. "I don't know what to do. I keep just pushing events aside. Meetings with Xana. Sissi visits. School. Is it normal to go on with life without pausing at everything?"

"Probably." Odd responded. "With everything going on, it's just lucky that were still living."

"Yeah." Xenon agreed, pressing her head father into Odd's chest.

"Something isn't right." Xenon said.

"What do you mean?" Jeremie asked as he looked over her shoulder. They were at the factory and looking at the super computer. It as the last period of the day. Xenon had the period free. She had gone to the supercomputer and could immediately tell something was wrong. She texted Jeremie with an urgent message saying something was wrong with the supercomputer. Jeremie had arrived and was looking at it with her.

"Look at this area in the ice sector." Xenon said as she opened a map of the ice sector. "At forty degrees north and sixteen degrees east." Jeremie did look. There wasn't any monsters or any of the usual sort that appeared on the map. The area by the tower was covered in what looked to be a bright mess. It was impossible to tell what it was by the map.

"What is that? And where did it come from." Jeremie asked. He, over the years, had never come across that.

"From analyzing it with the supercomputer, I can only think to call it an contamination." Jeremie looked at Xenon. "I think its from doing a return to the past with leaving Xana on Earth but I wont know for sure till I get to the ice sector myself and check it out." Jeremie nodded. He had grown accustom of Xenon knowing more about Lyoko than he did. He hung back and usually let Xenon deal with whatever problem was at hand. She knew so much more and had more experience.

"I'm going to go." Xenon said as she set up for a transfer to Lyoko.

"Without back up?" Jeremie questioned. "That dangerous."

"Jeremie," Xenon said, slightly annoyed. She opened up the map again except the contamination was smaller much smaller. It covered about a half of a dime worth of space. "This is what the area looked like when I called you. This," Xenon said opening up a current map of the ice sector, "is what it looks like now." The map showed it now covered a vast distance about a handswith of space. "If I don't see what the problem is, is could cover the whole ice sector and contaminate the other sectors. If it does that, all the sectors would probably become inaccessible even sector six which would mean no return to the pasts. Xana would find a nice hiding hole in Lyoko from the contamination and would still be able to activate towers. We would be able to deactivate towers nor do a return to the past." Her words spoke the true reality of what would happen.

"What if you get infected by getting to close?" Jeremie asked.

"I won't." Xenon said confidently. "I hold some of the keys to Lyoko. I can't get infected by it--"

"Then why not let Aelita go to?" Jeremie asked. He did not like the idea of Xenon going to Lyoko alone even though he knew she could handle it. He was always protective when Aelita went to Lyoko and he supposed it was rubbing off to her sister.

"Because Xana took her keys to Lyoko years ago." Xenon said shortly. "Now, I have to go. The contamination in spreading as we speak." Without waiting for another interruption, Xenon set up the Virtualization process and went to the scanner room. Jeremie took the seat in front of the supercomputer.

"Transfer Xenon, scanner Xenon, Virtualization."

The bell rang signaling the end of class. Odd exited his math class with Ulrich. It had been boring. Aelita and Jeremie had over the years been able to skip ahead in math classes and were taking math at university level. Odd and Ulrich walked to the courtyard looking for everyone else. Ulrich caught sight of Yumi and left Odd by himself. Odd looked for Xenon but didn't see her.

"Odd?" Aelita asked as she stood behind him.

"Yeah?" Odd said turning to face Aelita.

"Have you seen Jeremie?" Aelita asked a little loudly over the hustle and bustle as people left for their dorms or waiting for friends.

"No. Have you seen Xenon?" Odd asked. Aelita shook her head. "Maybe they're at the factory." Odd suggested.

"Alone? Without the rest of us?" Aelita asked. Odd stiffened. He didn't like Aelita's comment. Aelita's cellphone rang and she gave a sigh of relief. She looked at the number and smiled as she recognized the number.

"Jeremie? Where are you?" Aelita asked. Her green eyes widened in shock as she listened to Jeremie. "What do you mean vanished?! Yeah. I'll get to the factory and bring everyone." She hung up without even saying bye.

"Xenon vanished?" Odd asked. He wished it wasn't true even though he knew it was. Aelita nodded.

-()-

Aelita and Odd rushed to the factory. Odd called Ulrich, got an irritated sigh in response, Odd told him the situation, and Ulrich said he and Yumi were on their way. Aelita and Odd took the elevator down and walked to the supercomputer when it opened.

"So what happened?" Aelita asked.

"Xenon called me saying something was up with the supercomputer. I came and she told me about the contamination in the ice sector. She then went to Lyoko by herself. As soon as she got close to the contamination she and the contamination disappeared from Lyoko." Jeremie explained.

"Impossible without falling into the digital void and even if she did fall the containination wouldn't follow her." Aelita said. "Did you scan for any of her data?"

"Yes, but it came up--" He stopped as Aelita pushed him out of the way to sit in front of the computer. She typed quickly for a while in which Ulrich and Yumi came and Jeremie explained what had happened.

"Jeremie, do you have my father's diary?" Aelita asked, without looking away from the screen or slacking her pace in her typing.

"Yeah, but it's at school." Jeremie responded.

"Good." Aelita said. "Could you go get it for me?" Everyone looked at Aelita.

"Why?" Jeremie asked. Aelita turned to face them all. She had a blank expression.

"I just found something I've never come across before and I think there might be something in the dairy that could help." Aelita said impatiently as she wanted to have Xenon safe. "I want to know what Replikas are."

A/N Yay I finished this chapter. I thought I wasn't going to have the time. I've been so busy with homework, applying (which includes interviews, meetings, applications, all that fun stuff) for my school's exchange program to Japan for next year (which is weird because I'm in French...), and all sorts of fun stuff.

Sorry for even more drama. I can't help it. The characters seem to write the plot themselves and won't let me get a word in. A few chapters I estimated ten more chapters or so, but then the characters themselves at more and more to the plot. So I honestly have no clue when this story will end myself.

As always Review!
