(A/N) Hi y'all and welcome back to Code Lyoko: World Swap! It isn't essential to give introduction (At least I think it isn't). But I just choose to. Tell me if you want the welcome to stay or go away. Anyway, thank you for telling me my mistake, W.W.W. 147. I didn't know that it was spelled Ulrich. When I was typing the 1st chapter, there was nothing in my noggin! Just a big hunk of blind ambition. Anyway, nobody reviewed to say who they thought it was, so you'll just have to find out for yourselves in………

Chapter 2: The Infected Scanners

Odd and Ulrich let Jeremy go to get their skateboards so Jeremy could get his scooter. Yumi had long since retrieved her skateboard and was well down the sewer tunnel.

They had always used the sewer tunnel as a shortcut to the factory. But today, it seemed as long as the ordinary route.

The Factory was where Lyoko was contained. Well, then again, you couldn't really say that. What it actually held were the scanners.

The scanners were their ticket to Lyoko. They were used to materialize Yumi, Odd, Ulrich, and only twice, Jeremy into Lyoko.

Jeremy was the only one who knew how to operate the scanners, which was why he was so vital to the team. The only other person who knew how was Aelita. But she was, of course, stuck in Lyoko.

Once the four reached the tunnel's end, they climbed up a rusty ladder leading to a street in front of the Factory.

They didn't hesitate a second with worry of Aelita's well-being, and rushed into the building.

Yumi was the first to make it inside. When they had discovered the Factory, they also found that the stairs leading into the factory had caved in. So they had hung ropes from the ceiling and would swing down to the elevator that brought Jeremy to the operating lab, and Yumi, Odd, and Ulrich to the scanners.

Yumi swung into the elevator first, then Jeremy, Ulrich, and finally, Odd.

Jeremy then punched the red button that activated the elevator, and the metal door closed as the elevator descended into the depths of the factory.

The elevator came to a stop at the operating lab. It required an access code. Jeremy typed in the numbers needed, and the door opened to the lab.

Jeremy ran to his chair that swirled around a projection of Lyoko, and stopped in front of the computer that ran everything in the factory while Yumi, Ulrich and Odd went further down to the three scanners.

In a few minutes, Jeremy had linked up to Lyoko, and asked for Aelita. Her normal screen popped up, but nobody was there. Jeremy's heart sank as he heard Yumi calling up to him that they were ready to go.

He began typing their transfer coordinates, and everything was going fine. "Transfer Yumi," Jeremy, and he could see a wire frame version of Yumi's battle form downloading. "Transfer Ulrich," he said, and the same thing happened with Ulrich's battle form. "Transfer Odd," Jeremy said for the last time, and Odd's battle form downloaded. And it happened.

Suddenly, the three battle forms appeared on the screen, and each had a blinking exclamation mark in front of it. "Oh no!" Jeremy said. "How is this even possible?" Jeremy thought. Meanwhile, downstairs in the scanner room…

Yumi closed her eyes, ready to be rushing between the connection of Earth and Lyoko as bright light enveloped her. But instead, the scanner rushed open, and spit her out onto the cold metal floor.

Before she could think about it, Odd and Ulrich were spit to the floor beside her.

"What just happened?" Ulrich said rubbing his head from the new bump on his head.

"Well let's see. It looks like the scanners just spit us out like whenever Kiwi tries to eat one of my socks," Odd said, getting up from the floor and wiping the dust off of his face.

"Ha ha, very funny. Something is very wrong with the scanners, and we need to find out what and fast," Yumi said, getting up from the floor and approaching the elevator.

But suddenly, the doors closed. To the elevator, and to the scanners. And the lights went out.

"Ok Jeremy, very funny. But seriously, shouldn't we be getting off to Lyoko to see if Aelita is ok?" Ulrich said bumping into Odd.

"It isn't me guys. Something is seriously wrong. I can't reach Aelita, the scanners are infected, and the lights have gone out," Jeremy reported. He had put himself on speaker phone.

"Well find out fast, Jeremy. One of the scanners is acting funny," Yumi yelled, and it sure was.

One of the scanners was opening and closing like crazy. It was filling up with black smoke, and making very strange noises.

"Jeremy, get down here!" Ulrich practically screamed as the smoke began billowing out into the room and into the other scanners. And when the smoke enveloped them, it infected the other scanners as they began showing the same symptoms.

Meanwhile, in the operating lab, things were out of control.

XxxxxxxxxxxXxxxxxxxxxxX

"What's going on?!" Jeremy yelled at the computer. Like it would answer, but it was all Jeremy could do. His chair had locked into place, and he couldn't get out.

The computer was overloading with red exclamation marks, and the Lyoko projection was spinning out of control.

The elevator door was shutting and opening as fast as an out-of-control bus, and the lights were flickering from green to black.

Jeremy's chair had turned into a ride and swirled around the room at an alarming speed, taking Jeremy with it.

"Some-----one stop----- this stu-----pid chair!!! Jeremy said through nauseous breaths as the chair spun even faster.

Meanwhile, in Lyoko…

"Jeremy, where are you?!" Aelita shouted as she pounded the screen in front of her. She had been cornered in a tower by a pack of tanks, and they were moving and shaking the tower like an earthquake was upon it.

Her connection to his computer, the factory, even his cell phone had been broken. She had tried to warn him, and that was how Xana had found her.

Xana had located her in the forest region, and attached some sort of virus onto her. But this virus was not just a simple computer virus that could simply be deleted. Xana had made this specially.

He had gone to the real world through the scanners, and infected them with the virus as well. Xana was in search of Jeremy. He was going to drag Jeremy into the scanner, and into Lyoko.

When Aelita found this out, she looked on the positive side of seeing Jeremy. But she remembered the virus. The virus that was meant for a certain reason.

Xana's virus that had attached to her had something to do with the materialization process. Xana had set the materialization coordinates for Aelita's exact spot. And it had trapped her there. She couldn't move her legs.

When Xana brought Jeremy to Lyoko, he would be in Aelita's exact location. And that would force Aelita into the real world, leaving Jeremy stuck in Lyoko. And Aelita had to warn Jeremy.

Xana had sent a false alarm to Jeremy, so they would be lured to the Factory. Aelita couldn't believe it. She had been used as a pawn in Xana's cruel joke. She just hoped that the virus had scared Jeremy and the others from the factory. But it hadn't. Only because they couldn't leave.

XxxxxxxxxxxXxxxxxxxxxX

Jeremy tried to reach the computer, but his chair pulled him away. It was going up and down now, shaking Jeremy like a kid shook a soda for a joke.

The computer was acting very strangely. Xana's symbol had appeared all over it, and it appeared as if it were downloading Jeremy. A virtual shell of his own.

The download line went up and down over him like crazy, and Jeremy suspected something was wrong. And something was.

"Oh Jeremy," a cold, heartless voice called out to him, and the elevator burst open.

Jeremy would have jumped a foot into the air (had it not been for the chair restraining him) as black mist crept over from the elevator to his chair.

"Xana," Jeremy squeaked, and the mist swallowed him. "HELP!!" Jeremy screeched as he was dragged into the elevator.

The elevator dropped to the scanner room, and dragged Jeremy to the center scanner.

Odd, Yumi, and Ulrich were trying to reach Jeremy, but they were being levitated off of the ground, and were paddling through the air, trying to get down to the scanner that was pulling Jeremy in. But it was too late.

"Scanner, Jeremy," a deep, evil voice said, and the door to the scanner that Jeremy had been forced into slammed shut. "HELP ME!!!" they heard Jeremy screaming and pounding as the scanner began warming up.

Yumi, Odd, and Ulrich were dropped to the ground, and they ran up to the scanner. Odd started pounding on the scanner door as Yumi and Ulrich pulled with all their might on the door. But it would not budge.

"Transfer Jeremy," the evil voice repeated, and the scanner lit up in a flash of blinding light.

XxxxxxxxxxxXxxxxxxxxxxX

Jeremy pounded on the walls, but stopped in fear of ruining the equipment as the ring of light came up.

He was slowly lifted into the air, and the scanner lit up with an explosion of light, and Jeremy was sent flying into a tunnel of wires, and for the first time, he actually went to Lyoko.

"JEREMY!!!" Jeremy heard at the end of the tunnel, and he suspected it was Aelita at the end of the tunnel. But she wasn't at the end of the tunnel.

"JEREMY!!!" Aelita screamed again, but Jeremy noticed something. Aelita was right across from him in the tunnel. Just as Jeremy was making the switch from real to virtual, Aelita was going from virtual…to real.

Jeremy's clothes stayed the same, just a 3-D version of them, but Aelita's clothes changed.

Her ordinary Lyoko fashion morphed into a pink sweater, brown school shoes, and blue shorts. Then Jeremy realized what was happening.

Xana was switching them. He had attached a virus to Aelita, and when Jeremy's genetic code was read in the scanner, that would send her to the real world. And now, they would be forced to take each other's places in each other's worlds.

Jeremy reached his hand towards Aelita as he was pulled into the tower, and Aelita was pulled into the scanner. He was spit out onto the platform, with only two senses. Sight and hearing.

He turned around to see the portal closing as Aelita hit the scanner's surface, and the hole to the real world closed.

Jeremy sat down and began thinking. "This isn't over Xana," Jeremy said, and he lay down on the platform, thinking of how he was going to undo the giant mess that Xana had just created.

XxxxxxxxxxxXxxxxxxxxxxX

The scanner calmed down and opened, issuing a bunch of smoke, and Yumi, Odd, and Ulrich ran toward the mist, expecting to see Jeremy in a heap.

"How did you get out of that one, Einstein?" Odd said, and the lump in the mist began weeping.

"Jeremy, are you okay?" Yumi asked approaching the lump.

"Yes, I'm okay. But I'm not Jeremy," the voice of a young girl sounded, and a pink- haired teen emerged from the fog, making Yumi's, Odd's, and Ulrich's mouths drop.

"Aelita?" They all said in perfect unison, and Aelita nodded.

"But then…. Where's Jeremy?" Odd asked, and Aelita cried even more.

"He's in Lyoko," Aelita said, and they all three gasped.

"Well…do you know how to undo it?" Yumi asked, and Aelita shook her head very sadly.

"I don't," Aelita cried, and collapsed onto Yumi's shoulder, unconscious. She remained unconscious all the way back to Jeremy's room.

"Xana, what have you done?" Ulrich asked into the night as Kiwi began licking Aelita's face clean of tears, and Jeremy popped up on his computer.

"He's made a switch that is currently undoable," Jeremy said as they crowded around his computer.

"Where is the materialization program?" Ulrich asked, and Jeremy began.

"I saved it within the four regions of Lyoko. There's no way I can retrieve the other three. I don't have any weapons," Jeremy said.

"We'd have to come there one day at a time," Yumi said, and Jeremy nodded.

"The maximum you can retrieve per day is 50 per tower, so it will take approximately eight days," Jeremy said. "And I don't think we should risk taking Aelita to Lyoko. Since I don't know what type of virus Xana used, one of us may be deleted," Jeremy explained, and they all gasped.

"So Aelita? Can you last for eight days in Jeremy's world as an exchange student from Japan with the name Aelita Lyoko?" Yumi asked, pretty much filling in the holes for Aelita, and Aelita nodded.

"And Jeremy? Can you take Aelita's place in Lyoko, and enter the correct code whenever we need to undo Xana's doings?" Ulrich asked, and Jeremy nodded.

So for the next few days, they were going to have to make do while Xana schemed in his lair to destroy Jeremy for good, and keep Aelita in the real world with the virus, so he would never be shut down. And when they cracked, he would be waiting.
