Thanks for all of the reviews guys! Here's chapter 13!Please review!

Sissi screamed as Jim barged into her bedroom, charging straight for Yumi. It all happened so quickly for her. She ran at Jim to help out Yumi, but Jim avoided her and grabbed the collar of Yumi's shirt, lifting her high into the air. "Yumi!" Sissi cried in terror as Jim turned to advance at her.

"Go get Jeremie!" Yumi said as she tried to fight off her teacher. "Tell him that Xana is attacking!"

"Xana?" Sissi repeated in confusion, before dodging a grab that Jim made at her. She squealed in fear as she tried to escape.

"Just do it!" Yumi yelled.

"But…" Sissi looked around and saw her chance to get past Jim.

"GO!" Yumi shouted. Sissi wasted no more time and ran out her door and up the stairs. She pushed through a couple of people hurriedly and banged on Jeremie's door.

"Jeremie open up!" she cried. "Hurry!"

The door opened, revealing a very annoyed-looking Jeremie. "What do you want?" he asked, clearly angry about what had happened between Odd and Sissi earlier. Behind him, Aelita stood, looking a little more concerned than her boyfriend.

"Jim took Yumi!" Sissi told him desperately, hoping he'd believe her. "He grabbed her from my room, and I don't know where he's taking her! She told me to come get you, and tell you that someone was attacking… I think she said… Xana?"

Two pairs of eyes widened. "Jeremie, we have to hurry," Aelita said as she and Jeremie stepped into the hall.

Jeremie turned to Sissi. "Do you think you can go tell Ulrich?" he asked. "Tell him to go to the Factory."

"I will," Sissi said. "What's going on? I'm confused."

"Just go Sissi," Jeremie said as he and Aelita took off down the hall.

Sissi ran in the opposite direction, towards Ulrich's room, but something along the way stopped her. She saw Odd stumbling towards her, trying to run as he leaned against the wall for support. She cried out his name and ran to him, letting him lean on her instead. "Sissi, they got Ulrich," Odd said sadly. "We need to get out of here. Mrs. Hertz came into out room and attacked him. I got out but there are a load of teachers in the halls, rounding up students, and they know that I'm running from them. We need to get Jeremie, Yumi, and Aelita!"

Sissi nodded her head as she helped him run in the direction Jeremie and Aelita had gone. "Let me guess," she said. "You need to get to this factory place?"

"Yea," Odd replied. "How do you know?"

"They got Yumi too," she told him. "The others left." As they came to the stairs she looked over her shoulder and saw numerous teachers headed their way. Most had struggling students slung over their shoulders, but there were others ready to grab Odd and her. "Let's go!"

They got down the stairs and made a run for the doors, but someone else rammed into Sissi from the side. She cried out in shock as she and Odd fell to the ground, and she looked up to see her father standing over them. "Daddy?" she whispered fearfully.

When he tried to grab her she jumped away and stood up again in a defensive stance, ready to kick him if he came at her. And that was exactly what she did, causing something to fly out of the pocket of his jacket. Sissi froze and stared at the object, his set of car keys. "Sissi!" Odd cried out to alert her to another attack.

Sissi jumped out of her father's way and scooped up the car keys as she ran to the door that Odd was now holding open. She helped Odd run out to the parking lot towards her dad's car. She was so distracted that she didn't take notice of the other people around them until Odd yelled out. "It isn't just the teachers!"

Sissi looked to her right and saw two security guards approaching. "Hurry!" She almost sighed with relief when she saw the black car 20 feet ahead of them. "Get in!" she told the blonde.

Odd nodded and did as he was told, getting into the passenger's seat. Sissi got in on the driver's side and locked the doors. "Do you know how to drive?" Odd asked her a bit nervously.

Sissi put the key in the ignition and turned the car on. "Not well," she said nervously as she put the car in drive. "Buckle up."

Odd quickly secured his seat belt as the car pulled out of the parking spot. Sissi sped through the parking lot, swerving and narrowly missing a few people along the way. "Watch out!" Odd shouted as she nearly hit the gardener.

"Odd, where do we go?" Sissi asked frantically once they were out of the parking lot.

"The Factory is past the bridge," Odd told her as he pointed in one direction. "So turn left here."

"Ok…" Sissi turned a bit too sharply, but made the turn all the same. "I think I know how to get to the bridge… Um Odd… What's going on? It seems like you and your friends know all about it."

Odd never took his eyes off of the road, afraid that Sissi's maniac driving would kill them before they made it to the Factory. Fortunately there were no cars on the road at the moment, so it seemed safe enough. "It's going to sound pretty weird," he said. "Aelita is a virtual being, not a human. There's this virtual world called Lyoko that my friends and I found over a year ago.A program called Xana, though, lives in Lyoko, and it attacks our world."

"Aelita's from a virtual world?" Sissi asked skeptically. "How…?"

"We still don't know a lot about it," Odd confessed. "But we do know that we have to protect Aelita from Xana at all costs until we can get rid of a virus that he gave her and make her completely part of our world. Now, Xana attacks a lot in our world, and my friends and I have to take Aelita to the Factory so we can all go to Lyoko and stop Xana."

"If this Xana attacks so often, why haven't I heard of him," Sissi asked.

"You have," Odd told her. "You've helped us fight him before. You just don't remember, because we went back in time. My friends are the only people who do remember all of the returns to the past."

Sissi took her eyes off of the road for a second to look at him. "I still don't-"

"Sissi look out!" Odd yelled.

Sissi turned her head and screamed as she turned the wheel to avoid a large group of adults that were in front of the car. Odd shielded his eyes in case they hit someone. The car skidded to a halt and the teens saw the adults coming towards them, a few looking as if they were charging up electricity in their hands. Odd's eyes widened. "Sissi… I think every adult in the city had been possessed…"

"What do we do?" Sissi asked frantically.

"DRIVE!"

Sissi slammed her foot on the accelerator and they sped off. She saw the bridge and the Factory just ahead and smiled. "We're finally here!" she said as she stopped right outside of the Factory and jumped out of the car. She ran to Odd's side and helped him out.

"Come on," Odd told her as he leaned on her and ran in. "Let's get in there before those people do."

They made it to the elevator and shut the door just in time before the possessed adults showed up.

"Put me down!" Yumi shouted as she tried to kick Jim. Around her she saw numerous other students doing the same as teachers carried them as well. She had no clue of what Xana was planning, but she saw that they were headed for the school's auditorium.

Once inside the large room Jim threw her roughly to the ground and she got up and tried to run, only to have him throw her back again. It seemed that Yumi had been among the last group of kids to be thrown into the auditorium. All of the teachers were leaving, and the students soon found themselves locked in. Around her, Yumi heard numerous kids crying, arguing, and trying to force their ways out.

William was nearby, and he found her quickly. "Yumi are you alright?" he asked. Yumi nodded silently. "What the hell is going on here?" the boy muttered.

"YUMI!" someone shouted behind Yumi.

She turned around to see Ulrich running to her. She threw her arms around him. "Oh God, Ulrich," she said. "What's going on? How did he get control of so many people at once?"

Ulrich shook his head. "I don't know," he said. "But the others aren't here, so I think they got away."

"What do you think Xana is going to do with all of us?" Yumi asked fearfully.

"You're friends aren't here?" William asked, completely ignoring the bit about Xana. "Have you tried to call them? Maybe they can get help!"

Yumi pulled out her phone and dialed Jeremie's number as Ulrich and William joined a group of kids trying to bust down the seemingly fortified doors. "Come on Jer, pick up!" she mumbled.

"Hello?"

"Jeremie, are you and Aelita alright?" Yumi asked.

"We're at the Factory. Odd and Sissi got here too."

"Thank God. Have you called the police?" she asked hopefully.

"Yumi, there are no police. Every adult in the city has been possessed. I don't know how Xana did it. It's not good."

Ulrich and William suddenly stood still, smelling the air. "You smell it too?" William asked.

Ulrich's eyes widened. "Yumi! They've set the place on fire! They're going to burn us all alive!"

"Yumi, was that Ulrich? What's going on?"

"Jeremie," Yumi said shakily. "They locked us all in the auditorium and… and they've set it on fire…"

"We'll deactivate that tower."

Yumi didn't think that Jeremie sounded so sure. "Please hurry!"

"Aelita," Jeremie said looking very miserable. "I… I don't want to send you alone… but they need you to go now."

Aelita stood up from where she and Sissi were crouched over Odd, fussing over him and making sure he was alright. "Jeremie, I'll be fine," she assured him.

"She's not going alone," Odd said as he stood up, most of his weight being supported by Sissi because of his exhaustion from their escape.

"You aren't going in this condition," Aelita told him.

"It's not your decision," Odd said sourly. "Jeremie, send me. Aelita needs someone to protect her."

Jeremie looked indecisive for a moment before sighing and giving a nod. "Hurry up guys."

Sissi stood in front of Odd's scanner, watching him as he leaned against its wall. He looked exhausted, with dark circles around his blue eyes. His skin was pale, and his breathing was ragged. "Are you sure you should go?" she asked him. "It sounds dangerous."

"It is," Odd told her. "But I have to go. Or else the others won't make it."

Tears filled Sissi's eyes and she bit her lip. "Odd… I… about earlier…"

Odd frowned and looked at the floor. "Sissi, take a step back," he said. "Jeremie needs to scan me in."

Sissi watched as the doors of the scanner closed and blocked off her view of him. "I love you," she whispered as she wiped her eyes and sat down on the floor, prepared to wait until he returned.

I feel like I rushed it a little, but I'm not so good at writing the action stuff. I tried though, I hope you guys liked it so far. I wanted to write more, but this was getting a little long. Don't forget to review!
