I own Skye and Katie.

Skye started wondering around aimlessly, waiting for classes to get out so she could talk to Odd. Did he know that there was an entirely virtual world inside the factory?

The final bell rang, and students spilled out of the various buildings on the campus. Skye spotted her brother, Sissi, and Herve, and ducked out of the way into the bushes. If they saw her talking to Odd, Nick would blow up.

Someone tapped her on the back. "Why are you hiding?" Skye turned around to see Yumi.

"Oh! Yumi!" Skye said. She stood up. 'I was hiding from Nick."

"Why?"

"Because I need to tell Odd something, and if Nick sees me, he'll go nuts."

"Ah," Yumi said. "Is it about your date?"

Skye playfully shoved her. "No!" Skye peeked behind her. "I found something in the factory."

Yumi's eyes widened. "What?"

"I went down the elevator, and there was this giant computer there, and these pod things."

"Oh, crap," Yumi groaned.

"What?"

"You have to promise not to tell anyone about this," Yumi whispered fiercely. "Did you go into the pod things?"

"Um. Yeah." Skye said sheepishly. Had she done something wrong? "I had cat ears and a tail and this guy with shaggy hair was trying to kill me alond with these crab and spider things."

"That's William." Yumi said. "He was brainwashed by Xana, the thing that made those monsters. He's a very powerful computer virus."

"How do you know this?" Skye asked.

"Well, Jeremy actually found the computer, and the rest of us fight Xana. It's a secret we've kept for a long time, from everybody. We try to keep him from getting out and causing even more damage than when he's trapped in Lyoko."

"Is Lyoko that forest place?" Skye said.

"It's that entire world," Yumi said. Her phone buzzed. She flipped it open, read a text message, and shoved it back into her pocket. "Let's go." She grabbed Skye, and they raced towards the factory.

"Hold on! Wait!" Skye yelled. Yumi ignored her. "So Odd was lying to me?"

"Well, yeah." Yumi said. They made it to the manhole. "But it's only because he doesn't want you hurt. If you fall into the virtual sea there, you can't come back .You'd be stuck in Lyoko forever. He was protecting you."

They raced on the skateboards across the pipeline maze. Skye's ears suddenly pricked up. She heard scurrying. "Yumi, stop!"

Yumi stopped and turned to Skye. A little cube thing with a red circles in the middle of all it's sides quickly made it's way towards the two girls.

"Hit the deck!" Yumi yelled. They both dived to the side as the cube monster started to fire.

Skye heard more scurrying. "There are more coming." Skye yelled as she grabbed a loose pipe and batted the cube.

Yumi followed suit. "How do you know?"

"I can hear them." Skye shoved the pipe through the cube, causing it to short circuit. Sure enough, two more came through.

"Can you here them on Lyoko too?" Yumi asked as she rolled across the floor and hit one of the cubes into the water.

"Yeah," Skye speared the pipe through the other cube. She huffed a little bit since she was out of breath. "How'd you know?"

"Well, out natural abilities were magnified when we first came to Lyoko, and they were even better when we came back. Odd was always pretty perceptive, os when he came to Lyoko, he could see flashes of the future. Ulrich is really fast, so he got super speed. I used to do gymnastics, so I turn into a ninja pretty much." Yumi explained as they kept going down the sewers. "I guess you always had good hearing."

"What about Jeremy and Aelita?" Skye asked.

"I really don't know about Aelita. She was already in the computer when we found it, and we thought that she was just a piece of the program that was designed to fight Xana until about a month ago, when we found out her dad actually made Lyoko and put her there for her safety. She had forgotten until Jeremy made the materialization program for her to get out of the computer."

"Jeremy's the computer guy then," Skye speculated.

"Yep. We don't know anything about that computer stuff," Yumi said. They reached the ladder that got them to the factory. "Here we are."

They got in the elevator. "How'd you know the code, though? Odd said that he didn't take you down here."

"I just pressed a bunch of random buttons," Skye shrugged.

They made it to the computer room, where the rest of the gang was waiting. "Skye!" Odd said loudly.

"Hey," Skye said back.

"She told me she had found the factory, and you guys called, so I brought her," Yumi said. She turned to Jeremy. "Ulrich and Aelita already in Lyoko?"

Jeremy nodded. "Yeah, and they need help. Odd just got here too, so get moving."

"Transfer, Odd. Transfer, Yumi. Transfer, Skye. Virtualization!"

On, Lyoko, Ulrich was sprinting around Lyoko, slashing away at the Kankralots, and Aelita was throwing energy balls at some blocks. They temporarily stared at Skye.

"Skye!" Aelita cried. She flew out of the way of the blocks. Skye ran towards the blocks, and slashed them in the 'eyes.' "How...?"

"I came back here while you guys were in class, and found this place," Skye said. Her ears perked up. "More monsters are coming."

"Aelita, you should have enough time to get to the tower," Jeremy announced. "Everyone, get ready to fight."

Aelita went into the tower and the others prepard for battle. "Skye, I'm sorry that I didn't show you this place earlier," Odd apologized. "It's just that this is a big secret and--"

"It's okay," Skye interupted. " Yumi explained it. I understand."

Just as she finished that, some tarantulas burst through the forest. The gang went to action. Meanwhile, inside the tower, Aelita was having some trouble. "Jeremy,it won't except my password." She told the boy at the computer. "It got my handprint, but not my password."

"What? But that's impossible," Jeremy said. "There must be a glitch or something." Then it hit him. "Skye, what did you do to get out of Lyoko the first time?"

Skye jumped on top of one of the oversized spiders and dug her nails into it's head. "I just pressed a bunch of random buttons." Odd shot some arrows at the heart of the spider.

"I think you did something to change the password to clean the tower and get out of Lyoko," Jeremy said. "Get to the tower now!"

Skye jumped off the spider just as it exploded and ran for the tower. Aelita was standing by the screen in the center of the tower. "Do you remember what buttons you pressed?" Aelita asked.

Skye shook her head. "No. I was just so worried that the shaggy haired guy would come after me, so everything's a blur."

"Just, try to think of something you would use as a password," Jeremy said. "Think of what was running through your mind."

"I was hoping I wouldn't get killed."

"Something that has value."

Skye racked her brain. She typed in her brother's name, and then, things started to fall in the tower.

"Return to the past now," Jeremy said, and then everything was covered in white.
