Months had passed by since Katrina's first time back on Lyoko. As much as she hated being here, she valued her brother's life over her own feelings. Xana could have bugged Ulrich as a trap for Katrina, however they were lucky that wasn't the case. Katrina was now living on her own just two blocks away from the college she's currently attending. She passed all of her online classes with straight A's last semester so as promised, her parents let her go back to attend physical classes. She was happy to finally be on campus again after several years stuck on a virtual world and a few months after at home with her parents. She liked living on her own. It was close to both her parents and the college campus. The apartment also happened to be a few blocks away from the factory which is convenient if Xana ever launches an attack or they need her on Lyoko. She hadn't been on Lyoko since rescuing Ulrich. To be fair, it had been fairly quiet, and she told Ulrich to only contact her if it's an emergency. While it was quiet, they took the opportunity to destroy as many of the replicas as they could. So far only one was destroyed. Katrina had just gotten back from her classes. She tossed her bag onto the couch before going into the kitchen making herself a cup of hot tea. This had become a routine with her. While she waited for the water to boil, there was a knock at her door. She cocked an eyebrow not expecting any company. She opened the door and was greeted by Yumi.
"Oh Yumi…. how did you know where I live?" Katrina questioned. The only people that knew where her apartment were her parents.
"Ulrich told me. I hope it's okay that I dropped by" She responded. Katrina should have expected one of her parents to tell him. She let Yumi enter the apartment.
"So what's up? What are you doing here?" Katrina asked.
"It's been a while so I thought you could use an update on what's been going on since the last time you stepped foot on Lyoko. Your apartment is actually not that far from my house, so I figured I'd stop by" She told her.
"Oh okay. I was in the middle of making tea. Do you want some?" Katrina offered.
"No thanks, I'm good" Yumi responded. Katrina went back into the kitchen after she heard the whistle of the kettle. She placed a tea bag into a mug before pouring in the water. Afterwards she went into the living room where Yumi was.
"So if I remember correctly, Jeremie mentioned that Xana is gaining power from the replicas of Lyoko and that these replicas have to be destroyed in order to weaken Xana. The last time I spoke to Ulrich, he said that you guys only destroyed one replica so far" Katrina mentioned. Yumi nodded her head.
"There's a lot more than that now. Xana is also receiving energy from different super computers that are inside other factories linked to those replicas" Yumi explained. Katrina processed the information for a moment before an idea came to mind. It would make complete sense if that was the case, but she knew for a fact that there was only one Xana, and it was created in the same supercomputer that Jeremie was using. Unless, Xana was able to replicate himself as well, which would be a big problem.
"You wouldn't happen to know if Jeremie is at the factory right, now would you?" Katrina questioned after coming to that realization.
"No, why?" Yumi asked in response.
"I think there's a bigger picture to all of this" Katrina stated. "Come on, let's go to the factory. Text Jeremie, have him meet us there" She then told her. Katrina grabbed her phone before running out the door with Yumi following behind. They eventually made it to the factory and down to the supercomputer room. Jeremie was there sitting at the computer. He turned his attention to the elevator when he heard the doors open although he was relieved to see it was just Yumi and Katrina.
"What are you two doing here?" He asked them.
"Get out of the chair" Katrina ordered without explanation as she walked over to him.
"What? Why?" He questioned in response.
"Just get out of the chair" She stated not answering his question. If she was as scary as Ulrich described when she's angry then it would be smart to listen to her. He got out of the chair as Katrina took his spot. She typed something onto the computer which caused multiple windows to pop up on the screen.
"Yumi do you have any idea what's going on?" Jeremie asked her in a whisper.
"Not a clue" Yumi whispered back. Katrina was focused on the screen in front of her. She was going on a hunch, but if she was right, then that would mean that they were now one step ahead of Xana.
"Are you going to tell us what you're doing Katrina?" Yumi asked.
"I have a theory" Was all Katrina said.
"And that theory would be?" Jeremie questioned.
"There's a possibility that we're not dealing with just one Xana anymore, but multiple Xana's" Katrina stated. Jeremie and Yumi cocked an eyebrow in confusion. "The original Xana is inside this supercomputer which means that it only has access to the Lyoko that's programmed onto the same supercomputer." She explained.
"So that would mean that each replica would have its own Xana" Jeremie stated now coming to the same conclusion as Katrina.
"So when we destroy a Lyoko replica, would that mean we're also destroying a Xana replica?" Yumi questioned. Katrina nodded her head.
"Exactly" She commented with a smirk. Katrina eventually found the data she was looking for that would confirm her theory and confirm her theory it did. There was evidence of Xana on each replica of Lyoko.
