I don't own Harry Potter or Code Lyoko

Mister Puck

The elf backed away from a wolf before running away and tripping. The wolf pounced as Aelita screamed and woke up.

"WHO. IS. THAT. SCREAMING?!" yelled Sissi as she opened the door. "Grrr!"

"Um…um…well…you are!" said Aelita.

"Do you know what time it is?" asked Sissi as she glared at her.

"Five o'clock in the morning."

"Yes, that's right and this is the third night in a row you've woken me up! I have had it!" Sissi stormed off.

Later

Aelita entered the showers. And froze as she saw a wolf. She dropped the items she was holding and backed away before running.

"Out of our way!" said Sissi as she walked over with two other girls.

"Don't go in there! There's a huge wolf inside!" warned Aelita.

"Oh, really?" asked Sissi as she opened the door to reveal no wolf and a girl with glasses. "A four-eyed wolf!"

They started to laugh.

Outside

"It's a shame you didn't dream about me, Aelita! Because you know me, I'm a real dream come true!" said Odd.

"More like a nightmare to tell the truth, Odd!" said Ulrich.

"Shut up," said Harry as he wrapped his arm around Aelita. "Aelita's upset enough as it is."

"These visions of yours are becoming a real problem," said Yumi.

"It all started at the hermitage," said Jeremy as he pushed his glasses onto his nose. "I think you should go back there."

"What? Back to that old house?!" asked Odd. "I'm not sure if you remember, but last time, we were attacked by a cupboard, a lamp, and a gang of forks!"

"And I got knocked unconscious," said Harry.
"I don't like that place. It scares me," said Aelita as she stood up.

"We might not have any choice," said Yumi. "Your hallucinations are getting worse."

"Don't worry," said Jeremy as he took her hand. "This time, we'll be with you."

Harry clutched his head. "And I think I need to go to sector five. There's something waiting for me."

"Yeah, Xana," said Ulrich.

"The felling I'm getting isn't like anything I get from Xana. More homely."

Hermitage

"My legs are shaking! What's happening to me?" asked Aelita as the six of them looked at the deserted building.

"You're scared, it's nothing to worry about. It happens to Jeremy all the time!" said Odd as he looked at him.

"Come on, we'll see who's scared!" said Jeremy as they walked into the building.

"There! There! Stay down, boy!" said Odd to a book. Harry's eyes glazed over and he started to walk towards a room.

"Where are you going?" asked Jeremy as they followed him to the bookshelf. Harry picked up an envelope before returning to normal.

"What happened? How did I get here?" he asked as he looked around.

"You walked," said Jeremy as Harry looked at the envelope. "Almost like you were on autopilot."

"It's addressed to me."

"Uh, no it isn't," said Ulrich as he looked at the name. "Your surname is Stern, not Potter."

"It's addressed to my birth name." Harry ripped it open and read it. "Sector five? Did Waldo or whoever wrote this want me to go there?"

They walked out of the room and Aelita walked up the stairs into a room. She grabbed her head as she had a vision of a wolf.

"Aelita, you ok?" asked Yumi. "First Harry and now you. What's up with this place?"

"Yes, I mean I think so."

"Did you have another vision?" asked Jeremy.

"Yes, but it was different this time. It's as if something…or someone…was leading me to…there was something in a tree, that this one!" said Aelita as she took a poster off a wall. There was a hole behind it and a toy. She took it and said "Mister Puck!"

Kadic

"So to make a long story short, Aelita's never seen this toy? No, but she's been dreaming about it for days and she knows it's called Mister Puck." summarised Jeremy as they looked at it. "And Harry's been receiving images and letters telling him to go to sector five."

"It's not a gnome, it's an elf" pointed out Ulrich.

"Well, whatever it is, this whole story's definitely paranormal!" said Odd as Sissi took Mister Puck.

"So Aelita, still playing with dolls?" she asked.

"Give it back Sissi," said Harry as he tried to grab it. "It's to help her with her homesickness."

"Go fetch!" said Sissi. Harry glared at her and snatched it out of her hands and gave it to Aelita. A key dropped out of it and Harry picked it up.

"Alright, let's look at this triangle marked ABC," said the teacher as she drew it. "I is in the middle of AB."

"What's that key doing here?" asked Jeremy as he took it from Harry.

"What do you think it opens?" asked Aelita.

"I sure wish I knew."

Harry looked through the images again. "A lock…"

"Do I have a volunteer to demonstrate this?" asked Ms Meyer.

"Hey! A locker! It's the key to a train station locker!" said Jeremy loudly without a blind bit of attention to what the teacher was saying.

"Jeremy? I'm listening."

"Um, a complex number is called transcendent only if a rational coefficient polynomial route is a polynomial zero," said Jeremy randomly.

"Yes, indeed. That is a Sierpinski-Mazurkiewiczi paradox, but it is not the answer to our problem! So, zero!"

Sissi, Nicholas and Herb laughed at him.

Station

The group went up to the lockers.

"Well, this is it," said Jeremy as he looked at the right locker. "Would you like to do the honours?"

Aelita unlocked it and revealed a case with the letters F.H. on it.

"F.H., what does that stand for?" asked Ulrich as he looked at them.

"Fuzzy Hands. Fifty-cent Hotdogs. Fried egg!" suggested Odd as Aelita took it out of the locker.

"Egg" doesn't start with an "H"." said Ulrich.

"Just testing to see if you were on your toes!" said Odd.

"Uncle Waldo?" suggested Harry.

"That doesn't have an F or an H, Harry," pointed out Ulrich.

Harry facepalmed. "His fake name is Franz Hopper, idiot! F.H.!"

"Oh wow, music!" said Odd as they looked at the CDs and another letter which Harry picked up.

"Certainly not! Let's see what we can come up with…" said Jeremy as he put a CD into his laptop. "Franz Hopper's diary!"

"And another letter for me," said Harry as he read it. "I definitely need to go to sector five. Someone's waiting for me."

"Great," said Yumi as she put her arm around Aelita. "Maybe we'll be able to find out more about the Hermitage's owner."

"Sure," said Jeremy. "But not right away, everything is encrypted. I'll have to decode it first."

"How much time do you need? One, maybe two hours?" asked Ulrich.

"More like one or two years!" exclaimed Jeremy. "Harry might be able to do it in four month's solid work though."

The next morning

"Come on," Said Ulrich to Odd. "Time to get up."

"Just a little bit longer…"

"I'm going to take a shower," said Ulrich as he left. The light shook and a ghost came out of it. Kiwi barked at it. It went into Odd's ear and caused his outline to flicker before going out again.

Showers

"There a queue in here?" asked Odd as he came in. he looked at the door as the same thing that happened to him happened to Ulrich then to Harry.

"Xana does have a grudge," muttered Harry as the smoke went into a socket.

Harry's and Jeremy's dorm

"JEREMY! Jeremy!" yelled Ulrich as he shook him.

"Huh? What?" asked Jeremy as he put his glasses on.

"Xana's ghosts attacked us, me, Harry and Ulrich!"

"Uh…what?!" asked Jeremy as he sat up.

"Don't worry, no harm done. They ran away," Said Ulrich.

"There're still here," said Harry. "I can feel them watching us. Or it might be Xana. Same thing."

"The super scan didn't detect an activated tower," said Jeremy as he glanced at the screen. "Xana's attacked failed. That's weird, Xana can possess humans, but not you three…"

"It must have something to do with sex appeal! Haha!" said Odd.

"Yeah right, I'm sure of that!"

"It might have been due to our strong wills," suggested Harry.

"Maybe…"

"See you later," said Odd as the three exited the dorm. The ghost went into Jeremy and left, leaving the eye of Xana in his eyes.

Outside

"Running is the noblest event in athletics! Well, except maybe for the long jump, or the shot put, javelin, high jump, pole vault…" rambled Jim. "Some of you may associate running with cowardice. Nothing can be further than the truth. He who runs well, goes far."

Harry looked at Jeremy. He could sense Xana in him.

"Jeremy! Uh, let's see how powerful your strides are!" said Jim. "Hmph, for those of you with short memories, let me remind you that…uh…wh…what was I going to say? Er, right, uh, may I remind you that we start when I say "go". Not on "get set" and not on "ready". I mean…well, after "ready"…"get set" is when…I say "go"…right! Ok! On your marks, get set, go!"

Jeremy ran down the track before hurting his leg.

"Aaah! I twisted my ankle!"

"Yeah, of course you did!" said Jim. "You don't get strong muscles sitting in front of a computer! Herb, take him to the infirmary!"

"Jim? Would you mind if Aelita and Harry came with me instead?" asked Jeremy.

"Ugh, ok, whatever, go on then," agreed Jim. "Take him far away from me!"

"Jeremy! You're not limping anymore! Has your ankle stopped hurting?" asked Aelita as they passed a toilet where Yumi was.

"Or, rather, Xana," said Harry. Jeremy looked at them with the eye of Xana.

"Why are you always right?" asked Aelita as they backed off. Yumi looked at them as Jeremy started to advance on them. She called Ulrich.

"Yumi?"

"Ulrich! I think Jeremy's been possessed by Xana!" said Yumi.

"You sure?" asked Ulrich. "This morning Odd, Harry and I were almost possessed by a couple of ghosts, but they didn't succeed. Why would it work on Jeremy?"

"No idea! I saw them heading to the park. He was chasing Harry and Aelita."

"That's good," said Ulrich. "Harry can out run him even with Aelita. That's if he carries her."

"I'll check the super scan," said Yumi as she ran to the dorms. "Meet at the factory."

"Pitiful! A slug could've made it around faster! Ulrich, I'm counting on you to raise the level!" said Jim.

"Uh…ok! I've got to go to the toilet first though."

"So do I," said Odd as he stood up.

"Make it snappy. Who's next?"

Yumi

"Sector 1, ice sector, south, south-east," muttered Yumi as she wrote it down. She noticed the battered case and opened it.

Ulrich

Ulrich picked up the call.

"Xana's attacked," said Yumi immediately. "We have to stop Jeremy, and fast."

"Ok, we're on it," said Ulrich. "I hope the other two are ok. Harry will be reluctant to hurt Jeremy."

Factory

Harry dragged Aelita down the bridge as Jeremy followed them.

"Jeremy? …Jeremy, no! Listen to me, please!" pleaded Aelita. Jeremy shot electricity at them and Harry pulled them out of the way. They ran into the factory and were just about to be cornered in the elevator when Ulrich and Odd appeared.

"So, you going down too?" asked Odd.

"Be careful," warned Harry. "He can shot electricity."

"Boy, it's totally weird to be fighting against Jeremy! I mean, I don't want to hurt him, but…" said Odd as he and Ulrich took a fighting stance.

"My feelings exactly," said Harry.

Odd leapt at Jeremy but Jeremy sent him flying. Harry and Aelita attempted to climb up but Jeremy electrified the ropes, sending them back down.

"Ok, that hurt," moaned Harry. Jeremy walked over and brushed his face. "Don't do that!"

Yumi swung down the rope and knocked out Jeremy's legs with a spanner.

"We've got to get to Lyoko. Here are the coordinates of the activated tower," said Yumi as she gave them to Aelita. Ulrich walked into the elevator but Odd lingered.

"You guys go ahead, I'll take care of him! Grrr! Ok, over here, twinkle fingers! I have a good feeling we're really going to hit it off!" said Odd as he led Jeremy away.

Lab

"I need to go to sector five," said Harry. Everyone looked at him strangely.

"What do you want there?" asked Ulrich.

"I have my suspicions about something. Remember, I did get that letter telling me to go there."

Aelita closed her eyes and thought. "You'll have to be careful."

"I know. But on my own, I can get around much quicker."

"Harry, you're our best fighter," said Ulrich. "We need you."

"I'll meet you at the tower hopefully."

"Get to the scanners." Harry grinned and ran to the scanners as Aelita set up the program. "Transfer Harry. Scanner Harry. Virtualisation!"

Lyoko

Harry landed on his feet and ran to the edge of the forest. "Enter the code, Aelita." The transport orb arrived and scooped him up before racing to the other end of the sector and depositing him in sector 5. He waited for the entrance to reveal itself and ran through it. He raced through the labyrinth and spotted the mechanism. Harry climbed up the wall and touched it.

"Now to find him," muttered Harry as he searched for his target and found it. He ran off in the right direction.

Lab

Aelita set up the delayed virtualisation.

"How's it going?" asked Yumi.

"I'm not as good as Harry or Jeremy."

She set it off and went down to the scanners as the countdown reached zero.

Ice sector

"Look, there," said Aelita as she pointed at the tower. They started to run. "He who runs well goes far!"

"Is Odd the one who teaches you nonsense like that?" asked Yumi.

"No, as a matter of fact it's Jim!"

Factory

Jeremy attempted to punch Odd but he dodged and Jeremy hit the post instead.

"Whoa! I'm sure glad that post was there and not my face! Are there any other tricks up your sleeve?" asked Odd as he moved in front of the control panel.

Jeremy punched again. Odd moved and Jeremy broke the lift control panel.

"Uh-oh! That wasn't very smart, was it? Especially since you're the one who's gotta fix it!"

Jeremy growled.

Ice sector

"Keep your eyes open, huh? We don't have Jeremy to warn us about monsters this time!" said Ulrich as they heard cracking. "Uh-oh, I don't like the sound of that!"

Sector Five

Harry ran to where his target was, a room with a large pit leading to nowhere.

"Franz!" he called. "Uncle! Are you here?"

A pink ball formed in front of him.

Factory

Odd skidded into a post.

"How can you have a decent discussion with someone who has no sense of humour?!" asked Odd as Jeremy attempted to kick him but Odd tripped him up and tied his foot up in a chain.. "Whoa, easy does it! Haha! Not so clever now, huh?"

Ice sector

The ice got broken up by four Bloks.

"Bloks!"

They approached as the holes disappeared. Yumi pulled out her fan, Ulrich pulled out his sword and Aelita formed two energy fields. The Bloks started to fire. Ulrich tried to dodge but his leg got frozen. Aelita hit a Blok with an energy field, blowing it up. Ulrich used his sword as Yumi hit another Blok.

"Yumi, protect Aelita. I'll handle the remaining Bloks."

Yumi flipped over to them. Ulrich used triplicate and destroyed a Blok as Aelita destroyed the last one.

Factory

"Take this," said Odd as he threw the chain like a lasso. It caught Jeremy's wrist and he sent electricity down it, causing him to let go.

Sector Five

"Harry… you found me," said the ball.

"Yep. Like you said in those letters of yours that me and my friends found along with your diary. Why did you want me to find you?"

The ball sighed. "I was expecting you to be older. I wanted to say sorry."

"What for?" asked Harry, confused. "I take it you were the one who created Lyoko and Xana, right?"

"Yes."

"Well, I can't blame you. Xana was originally a simple program that rebelled, right?"

How did you know?"

Harry smiled. "You just told me and I saw it when Xana tried to take control of my body. He's after my powers."

"I know," said Franz. "He fears you but wants your powers for himself and the Keys to Lyoko from Aeltia. That's why I edited your avatar to help you protect yourself and my daughter."

"Aelita…"

"Yes. Keep your will strong. As long as you do that, Xana will never take control of you. He will never win."

"I also take it that you were the one who added that Xana detection program and sent me those images," continued Harry.

"I needed to make sure that you found me. I knew you'd trace the source eventually. I also wanted you to know when Xana was active." They heard a screech and Harry paled. "Our time grows short. You haven't discovered all that your avatar can do. A ninja hides in the shadows. Remember that. Your mother would be proud."

He started to move into the pit.

"What can you tell me about my mum!" Harry called.

"Read my diary..." He disappeared as the Scyphozoa entered and Harry backed into a shadow.

"A ninja hides in shadows..." He concentrated on Aelita and faded away.

Factory

"Hey sparky, scared of heights, huh?" asked Odd as he climbed up a rope to a walkway.

Jeremy jumped up to where Odd was.

"Ok, so you're not scared of heights…!"

Odd tried to climb higher but Jeremy electrified the walkway and knocked him off, leaving him sparking. He walked over to the shaft and ran electricity through the control.

Ice sector

More Bloks appeared.

"Is this what Harry has to deal with when he gets several lots of monsters?" asked Ulrich. "I don't know how he deals with it."

A Blok crept behind Yumi as she blocked lasers with her fan. Aelita formed ice to protect her.

"Thanks Aelita."

"I'm going to knock your block of, you dumb blockhead!" said Ulrich as he faced a Blok.

"Sounds like you miss Odd!" said Yumi as she threw her fan at the Blok, destroying it. "Your jokes are worse than his!"

She flipped through a Blok' s attack and threw her fan again. It missed and she used her telekinesis to redirect it.

"That's what I call a job," she said as she disappeared. The other two taped at the space she had been standing in. Aelita got her leg frozen. Ulrich used triangulate to destroy another Blok and ran to help Aelita. The last Blok stopped him as a s Scyhpozoa moved towards Aelita and picked her up. Ulrich destroyed the Blok as Harry appeared out of Aelita's shadow and attacked the Scyphozoa, causing it to drop her. It ran away.

"Thanks Harry."

"About time," said Ulrich. "Where did you come from?"

"Sector five."

"One of you has to deactivate the tower," said Ulrich.

Harry shrugged and used the tower's shadow to move over to it and entered. He rose to the second platform and placed his hand on the screen.

"Tut tut tut, uh-uh! It's not nice to devirtualise your best friends!" said Odd as Jeremy worked on materialising Ulrich. Jeremy electrocuted him again and picked him up.

"Yaaah!" Odd poked Jeremy's glasses with two fingers, aiming for his eyes. "Oh, never trust a guy with glasses! Ah!"

Yumi grabbed Jeremy's hand. He threw her across the room and dropped Odd. Jeremy tried to electrocute Odd again but returned to normal. He collapsed.

Later

"Well? How are you feeling?" asked Yumi.

"Deeehh…strange…I remember talking to Odd and Ulrich, and then after that, nothing. Just a black hole!"

"Xana took control of you!" explaIned Aelita.

"Oh!"

"He destroyed all of Franz Hopper's CDs! Apparently he had a problem with his notes," said Ulrich.

"Phew!"

"What do you mean, "Phew"?" asked Odd. "It's a disaster!"

"No it isn't!" said Jeremy. "Last night, I stopped off here and copied them onto a secure part of the computer. Only I will be able to get to them. Unless Harry decides to try to hack it of course."

"You're a genius, Jeremy!" said Aelita.

"There's something I don't get," said Ulrich. "How come Xana's ghosts didn't take control of Odd, Harry and me, and then have no trouble controlling Jeremy?"

"No idea!"

"I might have an explanation: apart from you, we're all used to fighting on Lyoko! Maybe that gives us more resistance to Xana!" said Yumi.

"Maybe…but then how can we protect me?" asked Jeremy.

"Hm…I just might have the answer!" said Odd.

Later

"Well?" asked Odd.

"That's the last time I ever set foot on Lyoko!"

"Why, just because of a couple of Megatanks?" asked Ulrich.

"It's not my thing," said Jeremy as he walked out. "You know, I think I'd rather be possessed by Xana than go back there! I'll just keep a look out for ghosts, that's all!"

"Well, what did he look like on Lyoko?" asked Aelita.

"He looked…how…how can I say this tactfully?" wondered Odd.

"Ridiculous," said Ulrich.

"That's the word!" agreed Odd.

"That reminds me," said Ulrich. "How did sector five go Harry?"

"Sector five?" asked Jeremy.

"I found uncle." Everyone looked at him.

"You went to sector five on your own and found your uncle?" asked Jeremy as they walked back to school.

"Yep. My cousin was taken to Lyoko too."

"I never saw anyone else over there," said Aelita. Harry looked at her.

"Aelita is your cousin," said Jeremy. Aelita froze. "Did Franz say anything else?"

"As long as my will is strong, Xana can't take control of me and that I have more powers."

Later

Aelita slept with Mister Puck.

"Come on Mister Puck, let's go for a walk in the garden!" said a young Aelita.
