Chapter Two

Return to the Past. Thirteen Years Ago

Jeremy's typing almost echoed through his empty room. The screen illuminated his face reflecting off his glasses. He had to get it, he needed to find it. Aelita's life depended on this vaccine. The virus that X.A.N.A had given her was a cowardly thing to do, but in order to survive, it was his only option. He had to think, it was his last option

'Its here. The vaccine is in Lyoko, I know it is' he thought.

He pushed his glasses higher up his nose and looked at the screen. The screen showed scans of all the towers in Lyoko, as well as a scan of Aelita's brain, it was focused on the part where X.A.N.A had put the virus.

'X.A.N.A would have made vaccine. It would be logical in case the virus backfired and he was infected with his own virus' Jeremy rubbed his head.

He was growing tired, he could not rest, not yet. Aelita, his love (yes he could admit that now he loved her) was in danger, and he needed to help her anyway he could. He could sleep later.

'X.A.N.A, is still a program. If he got infected by his own virus, he would be deleted. Aelita can become human so she is unaffected by the viruses' original programming' Jeremy looked at the screen that much he learned from data in the virus he scanned. That was all he could do scan.

'If only there was more that I could do' Jeremy shook his head. He felt almost useless but he could not give up.

"Jeremy, you really need to get some sleep." A familiar voice filled the air, and a face he adored appeared on the screen.

"Aelita, I'm fine don't worry about me." Jeremy lied he felt as though she could see right through his lie.

"Stop lying Jeremy, (he was right) I can tell you are tired. I've spent enough time out there to know what it's like to look and be tired." She scolded him.

Jeremy pulled his glasses off and rubbed the bridge of his nose. He was tired and the end-of-the-year exams were tomorrow.

"Sorry Aelita, but I know X.A.N.A has a cure. I just know it!"

She was taken aback just a little, but understood why Jeremy was upset. He cared for her as much as she cared for him.

"Jeremy, thank you for all your help but you're banking on chance. I mean if X.A.N.A had a vaccine he wouldn't make as easy as hiding it in a tower."

Jeremy's eye's widened and he started typing fast on the computer.

"That's it Aelita, you're a genius! Why didn't I think of that before?"

"Um... thanks?" Aelita replied with a puzzled look on her face.

"Alright that should do it. Aelita, we can get the cure for you tomorrow"

"Really Jeremy! How?" Aelita said her voice filled with excitement.

"I'll explain to everyone tomorrow after school."

"Alright then, good night Jeremy."

"Good night, Aelita."

Jeremy got up from his desk and collapsed on his bed. He was exhausted and was asleep in a matter of minutes.

The next day's events went by fast and the test went by smoothly for Jeremy at least. Odd fell asleep during his math test and woke up at the last five minutes (he finished his test by marking A,B,C,D in that order over and over again.)

Jeremy told everyone to meet him at the factory after school. He had finished all his tests and asked to leave early.

Jeremy typed on his computer, making sure everything was in proper order. If everything went as planned, they would be able to kill two birds with one stone. The first thing though was to cure Aelita.

The elevator door opened and Odd, Ulrich, and Yumi walked out.

"So, Einstein, what did you figure out?" Odd asked, walking up to the computer.

"Yeah, you said you had found a way to save Aelita." Yumi said also going to the supercomputer.

"Well this is going to be asking much of each of you, but if everything goes all right, we can deal with two of our problems." Jeremy said.

When no one said anything, Jeremy continued.

"What I have done is scanned the last tower X.A.N.A activated and scan the code in the tower. I checked other towers and they are all the same." Jeremy took a breath and continued.

"As it turns out when X.A.N.A activates a tower he has to be in the opposite of that area. In other words, like recently he activated a tower in the Polar Region so that means he would have to have gone to either the Desert Region or the Forest Region."

"So then what is it you want us to do." Ulrich stated.

"I believe that X.A.N.A has the vaccine installed on him so all I need to do is scan him and I can get the vaccine. What I need you to do is look for him and keep him busy while I scan him.

"Then what do we do after that?" Ulrich asked.

"Then we kill X.A.N.A!"

The room was filled with shocked looks. Even Aelita looked surprised.

Then began the final battle against an almost impossible enemy. The computer program X.A.N.A.
