Katrina left campus making her way to the factory. Luckily, Jeremie had contacted her at the end of her last class. She arrived at the factory swinging down to the elevator from the rope. She slammed her fist onto the button which closed the doors. The elevator descended down to the supercomputer room.

"What's going on?" Katrina asked Jeremie as she got out of the elevator.

"No time to explain. Odd and Aelita need you" Jeremie responded not taking his attention off of the screen. Katrina nodded her head getting back into the elevator heading down to the scanner room. She got into one of the scanners and Jeremie virtualized her right onto the Lyoko replica. She saw Odd being attacked by William and pulled out one of her laser pistols aiming it at William. She fired several rounds at him with each one hitting William in the back. Now, his attention was turned to Katrina.

"Aww is someone not happy that they're getting their butt kicked by a girl?" She teased after seeing the menacing glare on his face. William ran to Katrina with his buster sword in his hand. Katrina put her pistol back in its holster and pulled out her backup weapon which was a laser saber using it to fight off William. Their weapons clashed without either person taking a single hit from either blade. Odd took this opportunity and took a shot at William while Katrina had him distracted. Because of the damage William took from Katrina's laser pistol, the last shot from Odd took him out.

"Nice job you two" Jeremie praised. Both Odd and Aelita approached Katrina.

"Katrina, I'm convinced you're a goddess" Odd commented with a smirk. Katrina rolled her eyes in response. Ulrich wasn't kidding when he said his roommate was a flirt.

"Your timing was amazing" Aelita told her thankful that she showed up when she did.

"Thank Jeremie. He's the one that called me" She told her. Katrina looked around and noticed Yumi and Ulrich were missing. "Where's the other two?" She then asked.

"They're taking care of the supercomputer" Aelita responded.

"Are they okay? Are they going to need backup?" Katrina inquired.

"They're fine. They're almost at the supercomputer" Jeremie assured her while at the same time guiding Yumi and Ulrich through the factory.

"Jeremie, how are Odd and Aelita holding up?" Yumi asked as she and Ulrich made their way through the factory being chased by kankrelats.

"Katrina showed up and helped Odd take care of William" He responded. Both Yumi and Ulrich breathed a sigh of relief.

"It must have been bad if Jeremie had to call my sister" Ulrich commented.

"Your sister is amazing. I didn't think she would actually show up" Yumi commented.

"Jeremie must have contacted her when she got out of class or she wouldn't have showed up" He told her.

"Even if we were in trouble?" She questioned. Ulrich simply shrugged his shoulders not actually knowing the answer. Although he liked to believe that Katrina would drop what he was doing to rescue the group especially her own brother. They finally made it to the supercomputer room. Jeremie opened the door for them and Yumi shut it after the both of them passed through separating them from the monsters. Ulrich pulled out both swords slashing away at the supercomputer. Sparks flew from the computer with each swing of his sabers. Eventually the computer stopped working. Jeremie brought the two back onto the Lyoko replica after successfully destroying the supercomputer. They were teleported back into the sub still docked at the tower activated by Jeremie. The replica started disappearing which meant the group had to leave the replica quickly before they disappeared along with it. Aelita detached the sub from the tower diving back into the digital sea. This was Katrina's first time inside the sub and seeing the digital sea from this perspective.

"Wow, is it weird that this is exactly how I imagined the digital sea would look like?" She questioned.

"No, I thought the same thing" Yumi stated.

"Five years and yet this is the first time I've ever been in the sea. Which I guess is a good thing or I would've disappeared forever" She joked with a slight giggle.

"Don't joke about that" Ulrich scolded. He didn't want to imagine what it would be like not having his sister around. He was miserable in the five years she was trapped here in this virtual world.

"Ulrich you're so uptight" Odd teased.

"Shut up Odd! If it was one of your sisters, you would understand" Ulrich told him.

"I'm not close with any of my sisters so it wouldn't bother me" He said.

"I regret making that joke now" Katrina mumbled to herself. She knew it was a sensitive subject even though months had passed since she was materialized back onto Earth. "Can you two not argue while were inside the sub?" She requested.

"Anything for a goddess" Odd teased.

"Odd!" Ulrich shouted.

"Ulrich!" Katrina shouted. "Just drop it already" She said annoyed with her younger brother.

"Ha! Your sister likes me more" Odd continued to tease. Katrina rolled her eyes. She chose to ignore him for now. After returning to Sector Five, Aelita docked the sub in its hub. Jeremie teleported everyone out.

"Well that's one replica down" Yumi commented.

"Many more to go" Katrina chimed.

"How many more are there?" Ulrich asked. Katrina shrugged her shoulders.

"One of the replica's was created by Hopper as a backup in case the government decided to shut down his project. It's on a different computer in a secret facility that even I don't know the location of" She mentioned.

"You wouldn't happen to have any data on my father's replica, would you?" Aelita asked.

"There might be something on the CDs he made, but there's definitely nothing on the computer in the factory" She responded. "I don't have class again until next week so I can go over the CDs and see if I find anything"


A/N: Sorry for the delay. Chapter 5 should be out on Friday as planned
