I don't own Harry Potter or Code Lyoko

Plagued

In the sewers, rats were congregating because they could smell a pine cone. A rat tried to join them but was rejected. It ran up the sewer where it could smell food and entered a kitchen. Smoke came out of a socket it passed to some apples. The smoke covered the unfortunate rat. It struggled but it eventually got possessed. It then proceeded to bite the other rats who got possessed as a result.

Kadic

Jim was reading a magazine.

"Sorry but I can't speak any louder," said Jeremy softly. "I'm in a library."

"What's a library, Jeremy?" asked Aelita.

"A library is a databank where everything's printed on paper, and where you can't make any noise!"

"Oh, because I guess you need silence to concentrate on what you're studying!" said Aelita.

"Yes, and so as not to miss the match point!" said Jeremy as he watched Odd and Ulrich throw a ball of paper at each other.

Harry frowned.

"What's the matter Harry?" asked Jeremy, noticing his friend's expression.

"I think I'm bringing followed. Recently, I've been seeing an old man with a white beard and wearing a dress."

"Maybe he's new here."

"He's everywhere I go. Look. Up in the window."

The man Harry described was in a window, looking in. Harry clutched his head.

"I see what you mean. That is creepy. Xana attacking?"

"Yes, I think so. All the usual signs are there. I keep getting the picture of rats though."

"Hey! Quiet!" said Jim.

The game continued. Odd hit the paper really hard and Ulrich nearly toppled over but managed to hit the ball.

"Game, set and match!"

Ulrich toppled over with a crash.

"What are you doing here?!" asked Jim. "Do you think this is studying?"

Ulrich laughed.

"This is not the schoolyard! You are here to study!"

"We were just playing a game," said Odd.

"Ah! Ok, well if that's the way you wanna play, I can play just as hard as you can, my little friends! YYYYOU! Two hours detention! I'm...! Whoa, sorry about that, Sir, I uh..." Jim stammered as he grabbed and released the Principal's ear. Everyone started to laugh.

"I think it's pretty obvious what's happening Jim. Jeremy, Harry. I need you to come with me."

Later

Harry and Jeremy were depressed.

"Hey, what's up?" asked Odd as the three caught up.

"The principal told us that the school psychologist has been observing us and that he thinks we're overly gifted," said Harry. "We have to take IQ tests."

"So?" asked Odd. "Everyone knows that you two are the cleverest students in the year group. Harry does his homework in a fraction of the time it takes us. It's not like he found out about the lab again."

"If the tests show that we have really high IQs, the guy is going to see to it that we get sent to another school...," said Jeremy.

"Are you saying that he's going to send you two to a school for like, future Einsteins?" asked Odd.

"Yes. I don't want to leave," said Harry. "Even if it shakes my stalker off my trail."

"Wait, you have a stalker? Who is it?" asked Ulrich.

"Some old man."

"That is serious! If you're not here we can never go to Lyoko again, and Xana will be able to do what he wants! And you should tell someone about that man Harry!" exclaimed Yumi.

"It's not just that, guys! I don't want to leave here because of you all...you're my friends..." said Jeremy.

"Hey, they can't force you to change schools," said Odd. "Just say that you want to stay here."

"The psychologist creep couldn't wait to talk to our parents," said Jeremy.

"So?" asked Odd. "What's the big problem? You mess up on the tests, and they'll think you're a big moron! Nobody will ever know!"

"Dad expects the best," said Harry. "If the tests show that I'm too smart to be here, he'll move me for sure because of the scholarship money. I do have time to prepare though. My test is tomorrow morning. We're separated so we don't cheat off each other."

"The same here. With the parents thing," Jeremy sighed.

"I still don't see the problem," said Odd. "Just flunk the test."

"IQ tests are full of trick questions," said Harry. "You have to be smart to fail them."

"That's great. You are the cleverest students in the school," said Yumi.

"I'll so my best to flunk but I can't promise anything. I'd better get to the library."

"I'll see you guys later," said Yumi as she headed home. "Keep me posted."

Library

"Ah, hello Jeremy. Do you recognise me? I'm the school psychologist, Mr Klotz."

"Of course I do. Is it really true that you're planning to get me into a school for people like me? My parents are going to be so happy!"

"Well that's what we're here to find out. Now, to start off I'm going to give you a multiple choice test. It's a test in which you...well, I'm sorry, I'm sure you already know!" said Mr Klotz.

"Who, me? No!" said Jeremy, acting stupid. The psychologist gave him the test and Jeremy started to write down the wrong answers.

Cafeteria

"So what's for dinner?" asked Ulrich.

"Oh I dunno, some kind of hash. They all taste the same!" exclaimed Odd. "Where's Harry? I want to ask him something."

Sissi's dorm

Sissi entered her dorm and screamed at the shreds of fabric on the e floor.

"Oh no! It can't be! My brand new dress!" she picked up a piece of fabric. "Rat!" she dropped her shoe on it and it ran off.

Lyoko

A short distance from the tower Aelita was in, a tower glowed red.

Harry's and Jeremy's Dorm

"Jeremy? Jeremy?"

"Hey Aelita. What is up?" asked Harry as he sat at the computer.

"Where's Jeremy?"

"He's got an IQ test."

"A tower has been activated!"

"I'll run the scan program and tell it to send the results to my laptop. I have to go now though. It's time for tea. I'll come over once I've got the scan results."

Outside

Rats chewed through the power cables, resulting in a power outage.

Library

"Sir, don't you think we should stop now?" asked Jeremy as the lights went out.

"That would be silly. The tests are almost finished." Mr Klotz pulled out a torch and shined it on the paper.

Jeremy's phone rang but it was taken off him.

"After the test, you can take all the calls you want."

Sissi's Dorm

"What kind of school is this?" asked Sissi as she flicked a switch. She heard squeaking behind her and turned to see some rats. She scrambled onto the desk to get away from them and started to walk along the wall. Once she was far enough, she ran out the door.

Cafeteria

The lights flickered out.

"Uh. That's enough," said Jim as people started to mess around. "Everyone back to their seats. The lights will come on again soon. Stop all your clowning around!"

"Listen!" they heard squeaking and scuffling from the ceiling. Jim lifted one of the panels up and looked around to see lots of rats. Some of the panels fell out with rats on them. People started screaming and running around.

"We've got to get out of here!"

"Don't panic, I said! Just get out of my way!" ordered Jim as he ran to the door. It wouldn't budge.

"We're trapped!" said Ulrich as they looked at all the rats outside. "Xana waited until dark for the attack and we were in the cafeteria. He's raised an army of rats!"

"Nice going, Xana! Oh look. There's Harry." Odd pointed at him. "How did he get there? We're surrounded by rats."

Ulrich breathed on the glass and wrote 'get to Lyoko' in the condensation. Harry disappeared.

"Now to get rid of the rats," said Ulrich as he pulled out his phone and rang Yumi.

"Is that you Ulrich?" asked Yumi. "I know you're my boyfriend but I have to have some alone time. What?!"

Ulrich rang Jeremy. "Come on! Why doesn't he answer?!"

"The extinguishers Jim" shouted Odd. "Quickly!"

Jim was shaking against the wall. "Don't panic. Don't panic."

The students passed the extinguishers to Odd and Ulrich.

Sissi exited the dorms and saw the mass of rats outside. The students picked up trays to use as shields.

"Alright everyone! Outside!" ordered Odd. "There are way too many of them. We'll never make it," he said to Ulrich as they used the extinguishers to keep the rats at bay.

"Harry's on the way to the factory," said Ulrich. "We need to hold on as long as we can."

"Help! Help! Over here!" yelled Sissi. The rats turned their attention to her.

"Sissi! What's she doing here?" asked Ulrich.

"We might not like her but we have to help her or they'll eat her alive."

Yumi

Yumi cycled as hard as she could down the path, sending rats flying.

"Here she comes," said Ulrich. "I've never been gladder to see her!"

She cycled over to Sissi. "Your carriage, Cinderella!" Yumi said as she stopped. Sissi climbed onto the bike as they rode over to the rest of the students.

Library

"That noise is unbearable," said Mr Klotz as he walked over to the door.

"Listen, this racket has to… Rats!" he quickly shut the door as the rats leapt.

"Oh Xana… they'll try to eat though the door. We've got to barricade it somehow and I have to get out of here!"

They piled up as many books as possible in front of the door.

"Ok, keep doing it alone sir," said Jeremy as he ran to the table and started up his laptop. "I just hope we have enough time. Aelita?"

"Xana's activated a tower," said Aelita. "I told Harry but I don't know where he is. I can see it from here. I'll try to get a closer look."

Yumi

"Jeremy?"

"Have the rats attacked?" asked Jeremy.

"Yes they have."

"Ok. Get to the lab. Have you seen Harry?"

"I haven't. Hang on a second." She turned to the two boys. "Have you seen Harry?"

"Yeah, about five minutes ago," said Ulrich. "He's on his way to Lyoko."

"Jeremy, Ulrich says that Harry's already on his way. We'll see you at the lab."

She ended the call.

"We need to find a safe place. Does anyone know of one?"

"I do," said Jim. "The science building. It doesn't have any access to the sewers."

"Uh, Jim, there are sinks!"

"Any access big enough for a rat. Let's go."

"We'd better hurry," said Yumi. They made their way to the science building and Jim tried to unlock the door but his hand was shaking too much.

"Hey hurry up! We're nearly empty!"

Yumi helped Jim put the key in the lock and they ran in.

"Ok, up to the roof," ordered Yumi. "We'll be safer up there."

When they got up to the roof, they looked at the rats chewing on a tree which quickly fell over and shattered a window which they used to get in.

"We have to get to the factory. Jermyn will meet us there as soon as he can."

"How do we get there? There has to be a way…" Ulrich remembered when Harry had made a game that involved sliding down a rope. "Find a hose or something!"

They found the hose pipe and threw it over the edge. Odd went down first, then Yumi then Ulrich.

"Hey, wait, come back! What are you doing? No, come back! H-hey, come back here, hey! It's too dangerous down there!" yelled Jim as Ulrich jumped of the edge of the building.

"Too laaate!" yelled Ulrich as he gripped the hose pipe.

They ran to the manhole but it was full of rats.

"There's no choice," said Yumi. "We have to go the long way round."

Library

"Oh, this time we're the rats in the trap, and I don't like it at all…" said Jeremy.

"No rats. Please not rats," mumbled Mr Klotz as he flick the torch on and off. "When I was young, a rat went to my room…"

Jeremy looked at the window that was the target of the light. There was no rats. He snatched the touch and flashed it on a window with rats which caused them to run away.

"You stay here sir. I need to get to the photo room. Be right back."

With Harry

Harry slowed down. "Why are you following me?" he asked.

"Harry my boy. I need you to come with me," said the old man.

"Sorry. I've got more important stuff to do. I don't even know you and my parents told me to not go with strangers anyway, which I'm breaking right now but no one is going to remember this. I'm not your boy, by the way."

"My name is Albus Dumbledore. You do know that your parents are dead, right?"

"My birth parents might be dead but my adoptive parents aren't." retorted Harry. "They're the ones that raised me. Are you crazy or something for expecting a different reaction?

"You are Harry Potter," said Dumbledore, ignoring the question.

"Uh, my name's Harry Stern. Now I need to go."

"You are a wizard. I need you to go to Hogwarts and learn how to use magic. You're famous," Dumbledore said desperately as he saw Harry slipping out of his grasp.

"I know about my magic, though i call it differently, if you mean magic as a separate source of energy that allows people to warp reality, I don't want to go anywhere and I don't want fame for something my birth parents did. As for learning to use magic, I found a magical street and learned about my fame. I also brought some books to learn from in my free time. That means I know what happened that night and about this Voldemort person. Now, I really need to go. Oh, great. Here come the rats." He started to run again, towards the bridge which was covered with rats.

"I can get you out of here."

"Sorry, I have another way out. Anyway, I wouldn't go anywhere with you. Crazy old man, expecting me to go with a stranger. And before you say that I do know you, i only know your name and i don't go with people who have crazy dress senses. Even the people on the local street dress like normal people."

Harry backed up, ran and jumped over the horde of rats which were covering a lot of the bridge. Dumbledore gaped. Harry quickly ran into the factory.

Lab

Harry ran over to the computer and pulled out his laptop.

"Aelita! The tower's in the desert sector. I'm coming over."

"I can see it."

"What is this place?" asked Dumbledore as he appeared with a crack. "Where are you going? You have to come with me."

"I'd be surprised if you understood, being from the backwards world and I need to be here to stop the rats. Now, you need to be unconscious." Harry quickly used his magic to knock him out and set up the delayed virtualisation program and headed to the scanners.

Factory

"Great. Xana's trying to stop us from getting to the factory," said Ulrich. "Harry's probably already inside."

"How did he get over that?" asked Yumi as she pointed at the swarm of rats.

"He probably jumped over," said Odd as he headed to the water and pulled out a dinghy. "You know he now has superhuman strength and all that stuff so it's not as hard for him as it is for us. Some guys get all the luck. Care for a cruise?"

They used it to cross the river. The rats ran over the side of the bridge and into the water. The three quickly got into the factory and shut the door on the rats.

Library

Jeremy returned to the library with an arm full of cameras. He used the flash to scare off the rats. He passed one to Mr Klotz.

"If they come, use this."

"Stay…please don't go! I'm afraid of rats!" said Mr Klotz as Jeremy ran off.

Lab

"Harry? Are you there?" asked Yumi. "And why is there an unconscious man here?"

"Of course I'm here," said Harry. "Aelita's here too. That man is my stalker. He found out about the lab so I knocked him out."

"You really need to work on who you attack," said Yumi. "First police officers and now an old man."

"The police can't arrest me for attacking them considering it never happened. I guess the same thing applies here. He was trying to take me against my will."

"Now I need help on how to virtualise Odd and Ulrich."

"I'll tell you as I defeat theses Krabes."

Later

"Ok, that's done. What now?" asked Yumi.

"Type in the coordinates. Seventy-nine degrees west."

"Ok. Nineteen degrees west."

"No SEVENTY-NINE degrees west. Is the line breaking up or something? You need to hurry up. The rats must be in the city by now."

"Transfer Odd. Transfer Ulrich. Scanner Odd. Scanner Ulrich. Virtualisation."

Lyoko

"Well, we made it," said Odd. "I might be able to ask that question here. Wait. Aren't we meant to be near Harry and Aelita? Because I don't see them."

"Oh great. I entered the wrong coordinates so I virtualised you too far away from Aelita and Harry!"

"That's ok, we could use a little exercise to get warmed up!"

Ulrich and Odd ran for a few minutes.

"Do you see them now?" asked Yumi."You're late," said Harry. "You missed the hundred Krabe army that Xana likes to send against me. The Krabes are little more than cannon fodder."

"Well, we found them," said Odd. "Oh great. More Krabes."

"Well, it looks like we came just in time. Harry, can you let us deal with this?" asked Ulrich.

"Go ahead."

The Krabes dug their legs into the ground.

"Uh oh." Harry quickly turned into a Krabe and did the same thing.

"What's happening?" asked Odd. "Harry?"

The ground started to tilt.

"Don't bother answering."

"Harry? What is happening?" asked Yumi.

"Sorry Yumi. Harry's kinda preoccupied. He's now a Krabe. Xana's tilting the ground."

They started to fall. Aelita used her creativity to form a platform for them no land on.

"Well done Aelita," said Odd. Lasers started to fire as the Krabes that weren't Harry started to attack. Ulrich jumped in front of Aelita and took the shots. Harry changed into a Hornet and fired at them along with Odd using his laser arrows. Aelita took cover against the wall. With Harry's and Odd's combined efforts, the Krabes were quickly defeated. Odd still got devirtualised though.

"Now, how to get back up…. Oh great another Krabe."

Factory

"Smile," said Jeremy as he used the flash on the rats on the bridge. He ran into the factory and down to the lab.

"Need any help?" he asked Yumi. "And why is there an unconscious man on the floor?"

"He's Harry's stalker apparently," said Yumi as she got out of the seat to let Jeremy sit down. "Odd has been devirtualised and Ulrich has hardly any left. Harry is apparently a Krabe."

"He's a Hornet now," said Odd as he walked in. "So don't expect any speeches from him."

Kadic

The students and Jim cowered away from the door as squeaks were heard from behind it. The rats managed to bend the door and started coming through.

Lyoko

Ulrich leaped at the Krabe and stabbed it in the eye. One of the shots hit him and was devirtualised.

'Oh great, now it's just me and Aelita,' thought Harry. 'Oh, there's Yumi.'

Yumi threw her fan and cut off one of the legs. She threw it again and destroyed it before leaping off the edge. They quickly made their way up and Aelita entered the tower as Harry turned back into a ninja.

Aelita rose to the next level and pressed her hand against the screen.

Lyoko.

The files zoomed down the tower.

"Return to the past now."

The white light erased the events of the day.

"Did you find out a way to flunk the test?" asked Yumi.

"Now that I know all the questions, I should be able to cheat."

"Are you sure it's going to work?" asked Ulrich. "I don't want my brother, who's the only one that can help me, to move school."

"Anyway, I've got a fool proof way of flunking. I'm gonna get all of my answers from Odd!"

They laughed.

"Yeah, yeah laugh your heads off. But who knows, you might be in for a big surprise!" exclaimed Odd.

"Mind if I do that as well?" asked Harry. "I'll probably get the same test. Or we could convince them to let us do it at the same time so they can do other, more important things."

"Quiet!"

Harry's and Jeremy's Dorm, the next day

"You have magic?" asked Jeremy in disbelief.

"That's what Dumbledore called it. He also wanted me to go to a school called Hogwarts."

"And you declined?" asked Odd.

"Well, I didn't just flunk an IQ test just to go to another school."

"Hey, Harry! Can you help me with my work?" asked Odd out of the blue.

"What has brought this on?" asked Ulrich. "I mean, Harry has brought my grades up to what dad got when he was at school."

"I've grown bored of being the stupid one and Harry gets things so easily."

"Sure. I've got nothing better to do. It now seems that my Xana detection is getting better though. This time, I got the picture of what the attack was. Hey, do you want to help me confront Dumbledore again?"

"Sounds fun."

They all left the room.

Kadic Grounds

"Why are you following me?" asked Harry.

"Harry my boy. I need you to come with me," said the old man.

"Sorry. I've got more important stuff to do. And my parents told me to not go with strangers. I'm not your boy anyway."

"My name is Albus Dumbledore. Your parents are dead."

"My birth parents might be dead but my adoptive parents aren't." retorted Harry.

"You are Harry Potter."

"Uh, my name's Harry Stern. I know what you're about to offer me and I'm not interested. And if you try to target my friends, I'll hurt you."

"You are a wizard. I need you to go to Hogwarts and learn how to use magic. You're famous."

"I don't care about fame, I know about my fame and I learn from myself."

"You might hurt your friends," said Dumbledore desperately.

"I don't think so," said Harry. "I have it under good control. I trust my friends and they're in danger anyway."

"And if you target one of us, you target all of us," said Yumi.

"Anyway, I have one last thing to say…" said Harry. "Good bye." He focused, wiped Dumbledore's memory of his location and him ever finding him and transported him to the place he spends most time in. His office.

Everyone burst out laughing.

"I've never seen the time when Harry would speak up against an adult," said Ulrich between bouts of laughter. "He was always a teacher's pet."
