Disclaimer: I do not own Code Lyoko, if I did there should had been a fifth season and there was no need to write this fic.

Claimer: I own the plot.

Return of the father: Prologue.

Things changed in Kadic since that full-of-hate virus was gone. The gang grew, they were taller, their voices changed a little, but they kept the Lyoko spirit. The Lyoko spirit was the friendship above all, trading help for nothing. It was a huge friendship, one that could not be shut down by a switch of a supercomputer. They won the war against the machine. The machine is emotionless. And emotions made them to be motivated to fight XANA.

It was the wish of the whole gang to destroy XANA, but two people were the ones that were really motivated to fight it. It was the blond haired boy, the one with glasses, who decided to resign part of his life, hours of sleep, a lot of breakfasts, lunch and few dinners.

It was the pink haired girl, the one that XANA took captive some years ago and since then, she relied on the gang. Some could say that Jeremie is not well. But what he feels is that God gave him the opportunity to fight for someone, someone special. The gang was the one who saved Earth, but for what he fought was for one heart. Aelita's life was important to him; everyone knew that, except himself.

In one of those rainy days, Jeremie once again had a dream. It was a dream where he thought he could control it. But things went worse, and he couldn't control it anymore. Some call it a nightmare. Jeremie called it the dark side of his mind, where all the fears of him resided. In that dream, he launched a return to the past. After that, he was walking in Kadic, looking everywhere. It seemed another day for him, like a real one... But everyone ignored him. He turned out to be a ghost. He tried to talk to the gang in the cafeteria. For everybody, it seemed like Jeremie never arrived to the cafeteria.

They were talking like if nothing happened. But someone had a sad face. It was Aelita. One tear fell down her left cheek. Nobody noticed it. He tried to remove it. He couldn't. He is a ghost. Yumi asked Aelita what happened. Aelita replied with a question: "Have you forgotten him?" Yumi directed a sad look at Aelita. Aelita ran away.

Jeremie suffered and then, he finally knew what it was about. It was his subconscious that in his dreams talked to him. He tried to wake up, but the dream controlled him. It wanted to make see him do something.

Aelita cried. And nobody really cared. He shouts her name, tried to take her hand. He tried to slap her. Touch her hair. Said something to her, but nothing happened. After trying everything, she fell to the ground. And he felt that he was weak. And fell to the ground.

And he was supposed to wake up. He was still dreaming, because the scene was played over and over. It had little changes, sometimes was Yumi the one who was crying. Sometimes Odd had a laptop. Sometimes Ulrich was with Aelita, and she slapped hard in his face, he always asked why, but never came up with a good answer, there was a part of the dream could not be remembered by Jeremie... Sometimes, the dream that he feared most was the one where the gang was possessed by XANA. And then they disappear. The world turned black. And it started to capture him. The smoke captured him.

He finally wakes up. Tears run in his face, he never had cried that much. He tried to search for his glasses. He noticed that they were destroyed. In his dream, he made brute movements, like he was trapped with a web and tried to get out of it. The thing is that his mind was trying to say something to him. But it was hosted in his denial. He denied and ignored it. Every day he did.

He had to use contact lens, until he could go to an ophthalmologist and hope he would get the prescription for new lens. He managed to find the contact lens. He was going to classes and he obviously is going to go without lens. But there was a little detail. It's Sunday. Jeremie was so scared about that dream that he forgot for a while that it was Sunday.

The creator of Lyoko was killed by its own creation. Waldo Franz Schaeffer created XANA, XANA killed Franz Hopper. He was dead, killed one year ago. So was XANA, in the same day. That's right. 365 days ago. A tragic day for the whole gang, but Aelita… she suffered the most. She lost her father. The father she knew, but in dreams and mental images. What about her mother? She barely knew how she was called. She knew nothing else about Anthea. Her father was gone forever, his past was a mystery. Too much questions for Aelita were left in questions without answers.

Until now.
