I don't own Harry Potter or Code Lyoko. I don't plan to send Harry to any school.

Image Problem

Yumi and Aelita were running across the ice sector.

"The tower's 30 degrees north," said Jeremy.

"Harry, why didn't you come over?" asked Aelita as they headed over a path.

"Well, I've got to let you practice getting to and deactivating towers while I'm not there," said Harry as he typed on his laptop.

"You should be able to see the tower by now," said Jeremy.

"Its sticks out like a sore thumb," said Yumi. "But it's awfully calm over here."

"Hey, get it over with," said Harry. "That way, you can get back to kissing my brother quicker."

"Harry!"

"Be careful," warned Jeremy. "And stop teasing Yumi, Harry."

Aelita entered the tower and floated up to the platform.

"Jeremy, are you sure this is the right tower?" she asked. "There's nothing out of the ordinary here. It's not even activated."

"It's the one the scan picked up."

"I don't sense Xana's presence," said Harry after a moment. "And I can sense him for about ten miles."

"You said you felt pulsations, didn't you?" asked Jeremy as Yumi looked around after hearing a noise.

"I thought I did."

"I did feel Xana's presence a while back," admitted Harry. "But it was brief. Xana's planning something."

They heard Yumi scream.

"Yumi! Oh no, Ulrich's going to kill me!" moaned Harry. "I'm so dead! I was right when I said Xana was planning something."

"What's going on Yumi? Answer me!"

"Jeremy, Yumi's disappeared," said Aelita.

"She can't have just vanished. Hang on, I'll get back to you."

Scanners

"Yumi?"

Jeremy walked up to the scanner with Yumi's foot coming out. She was unconscious.

Drinks machine

Odd pressed a button for a drink. Ulrich's phone went off.

"Huh? Oh, hey Harry. What's up? What's wrong with Yumi? Ok." He ended the call. "Odd, Harry said that on her last trip to Lyoko, Yumi apparently disappeared and when she appeared in the scanner, she was unconscious. He thought it was best for him to tell me ahead of time. He's taking her to the infirmary."

"Hey, what's wrong with the hot chocolate?"

"Were you listening to me?"

"Hey Ulrich!" Sissi was running across to them.

"Hey, it's your fan club."

"Oh, I see Yumi has deserted you."

"Like your brain," said Odd.

"Anyway, I can't be around my girlfriend all the time," said Ulrich.

"Oh, it's bad to know that you can't be around me all the time. How about you clear up your time to spend more with me?"

"You're not my girlfriend Sissi. Yumi is."

Infirmary

"What happened to her?" asked Yolanda.

"I don't know," said Jeremy. "She just collapsed."

Harry frowned. He was sensing Xana's presence… from Yumi.

"Alright, back to class."

They reluctantly walked out.

Yolanda took Yumi's pulse when she woke up, snatched her hand out of her grasp and sat up.

"Now, now, lie down," said Yolanda.

Yumi grabbed her arm.

Corridor

Harry was still frowning.

"What's up?" asked Jeremy.

"Is it possible to use towers to create images of people?"

"Err, I don't know. Why?"

"I don't know but for some reason, I felt Xana's presence."

"He's probably planning another attack," said Ulrich.

"That's not it. I don't think Yumi came back from Lyoko."

"What do you mean?" asked Jeremy. "You saw Yumi."

Harry shook his head. "That wasn't Yumi."

"Are you imaging things?" asked Odd. "That was Yumi."

"Then explain why I felt Xana's presence exactly where Yumi was?" asked Harry. Jeremy's eyes widened.

"That was why you asked if it was possible to create images of people. You think Xana's done it."

Harry nodded. "After class, I'm going to Lyoko to have a look around and if I don't come back before the next class, cover me. I don't think there's anything there that can cause Yumi to scream like she did. Can you keep an eye on Yumi? If I'm right, she'll be acting strangely because Xana doesn't know exactly how to act as Yumi. It's possible that Yumi could be trapped on Lyoko."

"You saw that she was devirtualised."

"If Xana trapped her and managed to gain access to the link between avatar and ID card, it's possible that he made a false image of her being devirtualised. I just hope he hasn't killed her. He probably hasn't to maintain the copy better."

"I don't think that's it. But you're welcome to take a look."

Outside

"Ok, I'll see you later," said Harry as he walked away.

"Are you sure she wasn't hit by a laser?" asked Ulrich.

"I'm pretty sure. I would have seen monsters on the screen. Unless Xana found a way to hide them. Anyway, she had all her life points," said Jeremy.

"Something happened. I just hope Harry's not right."

"She passed out in the scanner. The return trips are pretty easy so I don't see why she came out unconscious."

"That's what you think," said Odd. "It's not easy at all."

"Alright so it's harder than I thought. But still, you don't pass out."

Ulrich looked around the corner. "Oh Yumi."

"Huh?"

"Yumi, can you tell us what happened?" asked Jeremy.

"I don't remember." Ulrich and Jeremy exchanged glances. "Come on, let's go to the factory."

"That's a crazy idea in your condition," said Ulrich.

"We've got more important things to do. Like eating," said Odd. Yumi walked past him.

"Harry might have the right idea," said Jeremy. "Yumi is acting strangely."

"Is Aelita safe?" asked Ulrich.

"Yeah. She was in the tower. Anyway, Harry's going to the lab. If anything happens, he'll be able to get over there and help."

Lyoko

Aelita was in the tower, looking at files.

"Hey, Aelita."

"Oh, hello Harry. How are you?"

"I'm fine. I'm just worried about Yumi."

"What's happened?"

"Well, when she was devirtualised, she came out the scanner unconscious. That doesn't happen, even if the return trip is rough."

"Huh? Harry, there's something odd here. I want to check it out."

"Wait for me to get there first. I have a feeling I know what it is."

"What?"

"Yumi."

He set up the delayed virtualisation program and went to the scanners.

Cafeteria

"You really can't remember what happened?" asked Jeremy.

"No nothing."

"It could be from the scanners," said Ulrich. "A bug or something."

"It could be Xana," said Odd.

"There isn't an activated tower," said Jeremy. "I'm starting to wonder if the transfers are becoming a health hazard."

"I don't think so," said Ulrich, "Harry has been there more than any of us and he's fine."

Sissi walked by.

"Do I smell something rotten or cheap perfume?" asked Odd.

"Ulrich, why don't we get together after school?" asked Sissi, ignoring Odd. "We can get to know each other better."

"That's tempting. Not."

Odd and Jeremy laughed.

"You should get to know her," said Yumi. "She could be nice. And she's pretty."

"Are you trying something?" asked Sissi accusingly.

Yumi looked at her.

"That's really nice. I'll be waiting for you." Sissi walked off.

"What are you trying to pull?" asked Ulrich.

"Nothing. Go on. Go out with her. She's been waiting for years."

The rest exchanged glances again.

"Miss Ishiyama. Come to my office right now," ordered Delmas. They walked off.

"I'm really starting to think Harry's right," said Jeremy. "The real Yumi wouldn't have said something like that. And she wouldn't have done something to go to the principal's office."

"Can you call Harry? Tell him what's happened?" asked Ulrich.

"I'll do it in our dorm. He might be on Lyoko so he might no answer."

Lyoko

They walked over to the ice structure.

"That orange thing wasn't there before," said Aelita.

"Before? You mean before Yumi screamed? My theory sounds more like what's happened to Yumi," said Harry. "Let's take a closer look."

"Harry? Are you there?" asked Jeremy.

"What's up Jeremy?" asked Harry.

"You were right. Yumi is acting strangely and she's been taken to the principal's office."

"There's this orange thing that wasn't here before, apparently," said Harry. "It could be some kind of prison. We're taking a closer look."

"Ok, I'll talk to you later."

"It looks like a guardian," said Aelita.

"A what?"

"It's used to keep people here and imprisoned."

Harry froze. "Wait. If Yumi's in there than who's on earth? Oh no. A fake Yumi! This could mean I was right and everyone's in danger."

"Yumi could be just having a bad day," offered Aelita.

"I hope you're right. But remember, we both felt Xana earlier. This could be a plan of his, to separate the group."

They headed up the path for a short time before getting shot at.

Kadic

"Yumi's been acting strangely ever since she came back from Lyoko," said Ulrich thoughtfully.

"She could have had a shock," said Jeremy as he joined them.

"What's the big idea of having a date with Sissi," asked Herb as he walked up to him aggressively.

"This isn't the time for this," said Jeremy.

"And I didn't agree to go," said Ulrich.

Delmas's office

"This is unacceptable Yumi," said Delmas. "Yolanda is still very upset. I'm giving you three hours of detention."

Yumi looked at him.

"Well, go on."

She didn't move.

"Is there something troubling you?"

She turned to look at him before turning away.

"Care to tell me about it? I'm here to help you. It's part of the job."

She didn't respond.

"Well then. I'm going to have to call your parents," he said as he reached for the phone.

"Not my parents."

"That's enough now." she grabbed his hand.

"I said, not my parents!"

She attacked him with the phone and the eye of Xana glowed on her head.

She walked out of the office and past Jim.

"Hey, Yumi." She ignored him.

"What's up with her?"

Harry's and Jeremy's dorm

"Once we got a way up the path, we were attacked," said Aelita.

"You should have just left Harry to go up," said Jeremy.

"It's safer with two of us," said Harry.

"Anyway, this fits Harry's theory."

"Should we go back?" asked Aelita.

"Yeah, I could go ahead and play pest control," said Harry.

"No. I'll send Ulrich and Odd as back up."

"You know I can handle it."

"It's not that. Harry, Xana knows you're the strongest out of all of us. That means he's going to try to get rid of you."

"And the same thing could happen to them. Harry took a risk coming here. Trust me, it's safer this way," said Aelita.

"Promise me you'll be careful," said Jeremy as the door opened.

"We will. See you."

"Oh, Yumi," Jeremy said as he looked at who entered. "What did the principal want?"

"We have to go to the factory," Yumi said.

"Oh, no. there's no reason to go. Anyway, you need to rest."

"If there's no reason to go, then why is Harry there?" she asked.

Jeremy frowned. "He has his reasons. Perhaps he wanted to check something there."

"I need to go to the scanner room."

"No. no one's going there until I give the order."

"Harry's gone to Lyoko."

Jeremy turned to face her. "And how do you know that he's gone there? I don't even know that he was there."

"I just do. Anyway it's important. I have to go to the scanner room," she said softly.

"Err, Yumi what are you trying to do?"

She took his glasses off. "There."

He blushed. "I don't think it's a good idea Yumi. If Ulrich catches us, he might get angry. You should go home and get some rest."

"Come on, Jeremy. Take me to the factory." She said as she leaned in.

"Jeremy, hurry up," said Ulrich as he opened the door. "What the…"

"Ulrich, wait. It's not what it seems," said Jeremy as Ulrich turned around and left the room.

"Bravo," said Odd sarcastically before leaving. Yumi gave a sinister grin.

No one noticed the microphone was still on.

Lyoko

"Did you hear that?" asked Harry. "We've got to get a move on."

"Yes, it's time to go," said Aelita.

They started to run up the path. The monsters shot at them but Harry managed to get up to them before they could take five shots and destroyed them.

"Well, that was easy. I'm starting to think Xana wasn't expecting us to get here. Aelita you can come up now!" he shouted before looking at the orange sphere. "What the… oh no. I was right!"

Class

"We can see this happening in certain insects," said Mrs Hertz. "This phenomenon is like a sort of natural cloning with no differences between them."

Odd blew a raspberry at Jeremy when he turned round. The bell went.

"Ulrich, you have to listen," Jeremy said as he pasted Ulrich.

"I don't want to speak to you, you nearly kissed my girlfriend."

"You know Yumi's acting strangely. I don't know what's wrong but it's like she's trying to split the group up. Either that or she's traumatised."

"Come on, let's go," said Ulrich. "Let's leave Yumi out of this."

"What do you think this is?" asked Jeremy. "I know Harry think's it's a fake Yumi but... what the!"

The computer was destroyed and it was a mess.

"All my equipment!"

"I'm staring to think that Harry's right too," said Odd. "This smells like Xana."

"Who was the last one to leave this room?" asked Jeremy.

"That's impossible," said Ulrich as he remembered. "Yumi doesn't have any reason to do this. Only Xana does."

"It's certain. Yumi is an imposter," said Jeremy. "Aelita and Harry said there was a guardian, a kind of virtual prison. Xana has to be keeping the real Yumi safe while he uses her form. We have to get to Lyoko. And it explains how she knew Harry was on Lyoko before anyone told her."

"Are we going to the scanners now?" asked Yumi.

"How long have you been there?" asked Ulrich.

"I only just got here."

"Yeah, let's go."

Scanners

"Are you ready? Let's go. Transfer Ulrich. Transfer Odd. Transfer Yumi. Scanner Ulrich. Scanner Odd. Scanner Yumi. Virtualisation."

Yumi stopped the doors on the scanner closing while the boys were scanned. She then walked out and started to destroy the scanners. When Jeremy came in, she punched him to knock him out and continued to destroy the scanners.

Lyoko

"Where's Yumi?" odd asked when he didn't see her.

"She's still on earth. Jeremy, tell Aelita to get the real Yumi free!"

"Aelita and Harry are on top of the structure behind you," said Jeremy. "Aelita, did you get what Ulrich said?"

"Ok, we'll go."

Harry and Aelita.

Harry shrugged. "You'd better get onto it Aelita. Do you want me to deal with that activated tower?" he asked as he noticed the red glow.

Aelita nodded which caused Harry to run off. He quickly encountered the other two.

"What are you doing?" asked Odd.

"Deactivating the tower, bye."

The two shrugged and continued on.

"Hey, Aelita. What are you doing?"

"I'm going to create a clone of Yumi." Aelita said as she started to use her creativity. A clone soon appeared and the guardian blew up, releasing Yumi.

"What happened?" she asked.

"Sorry, we've got to deactivate the tower," said Odd. "I'm worried about Jeremy since we haven't heard from him for a while. The other one might have got to him."

"The other what?" asked Yumi.

"The other you."

"Devirtualise me. I've got a meeting… with myself."

"How?"

"You're armed, are you not?"

Ulrich shrugged and impaled her on his sword.

"Harry's taking a while," said Aelita.

With Harry

"Why won't these Krabes die?!" He managed to destroy the last five Krabes. "Huh. Looks like Xana has to send more than fifty Krabes next time."

He walked into the tower and went to the next platform. He touched the screen.

Harry

Code

Lyoko

Earth

"You know, you look like me on a bad day," said Yumi as she faced the clone. They both got into a fighting stance before the clone faded away.

"What happened?" asked Jeremy.

"I think Harry just deactivated the tower."

"I need to do a return to the past."

"Or I could do it," said Harry as he stepped out of a scanner to the other two's looks. "What? Is it against the rules to devirtualise myself? Hello Yumi."

"How do you know I'm the real one?" she asked.

"The same way I knew the other was a fake. Besides, the tower I deactivated was keeping it here so when I deactivated it, the clone disappeared."

"Ok Harry. You activate the return to the past."

Lab

"Ok then. That's the last thing. Return to the past now!"

The familiar white light engulfed everything.

Earlier

"This proves that materialisation is possible," said Aelita. "At least, for a programs."

"This is crazy," said Yumi. "Xana's helping us."

"I think it's unintentional," said Harry.

"Back to work then," said Jeremy.

"You could just ask Xana for it," said Odd.

"I doubt Xana's going to give it to him," said Harry. "In fact, if Jeremy did ask, I'd think Xana's response would be to attack him. And even if Xana did give it to us, I wouldn't trust it."

"Anyway, how did you know I was the real one Harry?" asked Yumi.

Harry smiled.

"The other one gave me a headache for the short time I was around her. And whenever there's a Xana attack, I get this feeling. Like someone's watching me."

"But that doesn't explain how you knew it was me. All that tells us is that you knew there was a Xana attack. Or that you're paranoid."

"The feeling gets stronger the closer Xana is. And I get this mental itch when I see the source. Or a massive headache. Or some other thing telling me that it's wrong somehow."

"Yes, yes. We know how you're a living Xana detector," sighed Jeremy. "I knew it was fake when she started to flirt with me."

Harry chocked. "She flirted with you?!"

"She wanted to get to the Scanners to destroy them. This was one of the attempts to make me take her. Anyway, I knew the real one wouldn't flirt with me."

"Who says I wouldn't?" asked Yumi as she walked over to him and took his glasses off, causing him to blush.

"That's enough Yumi."

"What, are you jealous of Jeremy?"

"What… NO!"

"Yeah, he is," said Odd.

"If I had gone to Lyoko instead of Yumi," said Harry thoughtfully. "It could have been me Xana copied."

Odd laughed. "Yeah, right. You're too fast for him to catch. And you have too many weapons. And it's pretty hard to sneak up on you."

"But, if he did, would you had thought anything of me going to the factory?" asked Harry. Everyone paled.

"The scanners would have been destroyed before we could stop it happening," said Jeremy.

"And I'd probably be dead. That's enough of the morbid stuff. What did I miss while I was on Lyoko?" asked Harry.

"How did you know about all that stuff anyway?" asked Odd. "With the Yumi we got being fake and the prison. And about Xana. And about you dying."

"Well, I knew the Yumi we got was fake because I felt Xana, Odd. I believe I just told you that. The prison was the only way I could think of that would stop Yumi coming back to Earth. As for how I know about Xana, well. I've been doing research on him, even though I don't have much to go on. if Xana had succeeded, he would have probably gotten rid of whoever he got permanently. Now didn't I say to stop with the morbid stuff. What did I miss?"

"Ah, not much. Just the fake telling Ulrich to go out with Sissi," said Odd.

Yumi growled.

"Look who's getting possessive. Am I to call you sister now? When's the wedding? And when is the baby due?" teased Harry.

"HARRY!"

Everybody started to laugh.
