Chapter One: Reconstruction

[Jeremie POV]

August 20, 1995

One week has passed since Lyoko was destroyed and we lost Hermione Granger and William Dunbar. One week since I had received the coded message from Franz Hopper. I had decoded it that evening and found out that he had given us the data we would need to rebuild Lyoko. Aelita and I had started that night. I also found out that we would need to get data from Sector 5 so that Franz could fix Hermione's corrupted digital signature.

So now, Aelita and I were putting the finishing touches on the new Sector 5. We were also working on the new vehicles for Harry, Ron, and Hermione. With Ginny now as a Lyoko Warrior, all eight of them wouldn't be able to fit on just three vehicles.

While everything was loading, I used the supercomputer to call Principle Delmas using William's father's voice. I thought I made a pretty good grown-up, if you ask me. The call went well, but I stumbled once. It was about Sissi, how "Mr. Dunbar" knew the principle's daughter's nickname. I explained that "William" always talked about Sissi.

The next day, Ulrich, Yumi, Odd, and I sat at a bench in the crossroads. "Aelita and I are rebuilding Lyoko. We have been working on it every night this past week. With all of the we received from Aelita's father, we should be done tonight."

"Oh, that's why you look like a zombie," Odd said. "I thought you two were partying every night. To think I wanted to join you!"

"Once, Lyoko is reconstructed, I'll send Aelita, Harry, Ron, and Ginny to Sector 5 to retrieve data to repair Hermione's digital signature. Once we do that, I'll try to localize William. We'll all meet up at the factory tonight."

"Wait," Ulrich said. "Why aren't we going to Lyoko? We've been to Lyoko more often, and Ginny's just a beginner. Why are you sending her?"

"Well, Ulrich, put it like this: They will have more practice for future battles, and plus, it's the middle of their summer. They can afford to sleep in. I'm staying because of my good grades, and all Ron knows how to do on the computer is bring up vehicles."

"We're going to Lyoko next time, Jeremie, and don't you forget it," Yumi said. She picked up her black back and walked into the Science Building.

[Ron POV]

I was excited. I was going to see Hermione again soon! When Aelita announced that Lyoko was almost back during dinner, we all cheered. Mum even allowed Ginny to come.

When Aelita's Muggle thing buzzed, we ran down the stairs of Number 12, Grimmauld Place, waking the portrait of Sirius's mum. After we all Flooed to the Hermitage, where Aelita used to live, we ran outside into the overgrown garden and through the door to the sewers. After five minutes of running and the putrid stench, we finally got to the factory. I swung on a rope a little better than the last few times. We walked into the elevator, and a few moments later, the door opened to a green room with that thing in the center. Jeremie was already there, and Odd, Ulrich, and Yumi were standing around him.

"Hey, guys!" Jeremie said cheerfully. "Now that we're all here, let's start." He pressed some buttons, and a beeping sound came from the computer. Aelita and Jeremie stared at the screen hopefully.

Eventually, Aelita looked away, her pink hair covering her face, and said, "The information my father gave us wasn't enough."

"Wait!" Yumi said, pointing at something. "Look at that!" The beeping stopped.

"Yes!" Jeremie shouted. "All we have right now is Sector 5, but I'll get the other sectors up soon. Aelita, Harry, Ron, and Ginny, go to the scanners."

Odd, Ulrich, and Yumi walked back into the elevator. Aelita walked over to some rungs in the wall and climbed down. Ginny, Harry, and I followed into the yellow scanner room.

"Ladies first," Harry said, pointing at the scanners.

"Aw," Aelita said. "You're too kind."

Before she and Ginny stepped into the Muggle contraption, it closed and reopened. I saw someone with navy blue hair hunched, and he straightened up. He looked strangely familiar.

"William?" Aelita asked.

AN- William has returned! Will everything be like it was in the show? When are they going back to Hogwarts? September 1! That's when. Merry Christmas, everyone!
