I don't own Harry Potter or Code Lyoko

Code: Earth

"This should work this time," muttered Jeremy as Harry peered over his shoulder. "Launching plan alpha."

The computer came up with a positive.

"Looks like it's time to get Aelita over here," said Harry as Jeremy called Yumi. "And shut down the computer. I'm going to miss that."

"Yumi? Yumi, it's me! Ok, I just launched plan Alpha! My five dry runs have all worked!" exclaimed Jeremy excitedly.

"Ok, tomorrow, I'll talk to my parents," said Yumi as she stood in a random room at her house.

"That's great. Harry and I will talk to Ulrich and Odd."

"See you tomorrow," said Yumi as she cut the call and turned her phone off.

Jeremy slid his chair out and they climbed into bed.

Jeremy dreamt of his time in Limbo when Aelita came to get him.

Harry dreamed of Kankrelats invading the school before waking up. "Weird dream." He went back to sleep again.

The next day

Yumi's dad shoved a clump of noodles into his mouth and chewed. He finished the bowl as Yumi came in.

"Uh, Mum and Dad? Can I talk to you for a second?" asked Yumi. "It's about my pen pal, uh…um, you haven't changed your mind about her living here for a while?"

"No, but tell us a little bit about her, Yumi. Well, we don't even know her name!" said Yumi's dad.

"She's called Aelita."

"Aelita what?" asked her mum.

"It's Aelita…uh…um…Lyoko!" said Yumi with a slight pause as she made up a name. Her parents didn't notice the hesitation.

"Is she Japanese?" asked Yumi's dad.

"Well, uh, yes! She is!" said Yumi.

"What do her parents do, dear?" asked her mum.

"Uh, they uh, they work with computers."

"Well…alright then. She's welcome to stay with us."

"That's fantastic! I adore you! You won't regret it! She's really so nice! See you tonight!"

Yumi kissed her parents on the cheeks before running out of the room.

Principal's Office

"Very well then, uh what is your cousin's name, Odd?" asked Principal Delmas as he read the letter.

"Aelita."

"Hm, Aelita…and uh, where does she come from?"

"She's from uh, Holland!" said Odd after a slight pause. Delmas didn't notice.

"Hm…mhm! Well, her papers are in order and your parents have recommended her highly, so I see no reason why she can't attend school here! Let me know when she arrives!"

Outside

"Yesss!" exclaimed the boys at the same time as they slapped hands and laughed.

"My brother is going to be so pleased," said Ulrich as they started to move. "So is Jeremy. They worked so hard on finding a method of getting Aelita here."

"Fantastic!" exclaimed Odd as they nearly walked into Jim.

"Ok, what are you two up to, huh?" asked Jim. Odd gave a nervous chuckle. "You know this building is off limits to students, especially at eight in the morning!"

"We had an appointment with the principal," explained Ulrich. "It was about Odd's cousin attending school."

"What a lame excuse!" exclaimed Jim with a laugh. "What do you think I am, huh, an idiot?"

"Well…"

"Quiet! Yeah, and I'll bet you think I'm not onto your pranks with Jeremy, Harry and Yumi! You disappear in the park like some sort of magic, you plot in your rooms! You're up to something!"

"Hey, it's not a crime to talk to our friends in our rooms!" exclaimed Odd as Jim crouched down with a shaking fist.

"Maybe not…now you listen up! One of these days I'm going to find out what the five of you are hiding! And now, to the cafeteria! Hurry up!"

"We'd better be careful about Jim. If he keeps playing detective, he's going to find our secret passage… muttered Ulrich as they left the building. Jim watched them go with a frown.

Yard

"You know what I think?" asked Ulrich. "We need to warn the others about Jim." Odd nodded.

"Hey guys!" shouted Yumi as she ran over to the two. "My parents said she could stay."

"So did the principal," said Ulrich. "Odd, that was a pretty good letter you faked from your parents!"

"I can't say I'm proud of what I did, but it was for a good cause," said Odd guiltily. Ulrich's phone rang.

"Jeremy? What's up? Ok. Be right there."

They ran off towards the dorms.

Harry's and Jeremy's Dorm

Jeremy ran the materialisation program again with everyone watching. It showed up positive.

"That's it! We got it this time!" exclaimed Jeremy happily. "It works! It works! I can hardly believe it!"

"I knew we'd get there eventually," said a grinning Harry. "You couldn't be more excited if you tried Jeremy."

"YEEEEAAAH! YAAAY!" yelled the other three as they hugged the two geniuses.

"Get off me! You're braking my laptop! It has your vehicles on there."

Outside

"It's fantastic! You can find any type of music you want!" said a random student as Jim walked past.

"Hey, Sissi! Have you seen Ulrich and his gang this morning?" asked Jim as he walked past and stopped.

"Well yeah."

"Where, in the cafeteria?" asked Jim again as he knelt down to their level.

"No, I saw them going to their rooms, Jim," said Sissi as she thought of something.

"Yeah? Thanks for the tip…"

"It is pretty strange to go to their rooms at this hour! I said to myself, now why would they be in their rooms now with someone who isn't even a boarder?" asked Sissi rhetorically.

"You mean Yumi Ishiyama is with them?" asked Jim.

Sissi nodded and Jim shoved past.

"You're meaner than I thought!" said Nicholas to Sissi who smiled as she watched Jim walk off.

"Harry is going to be all mine…"

"You do know he's single, right?" asked Herb. "And why have you suddenly fixated on Harry? I thought you liked Ulrich."

"Because he's handsome, nice, clever and he's got lots of money. He also does the occasional professional work even though he doesn't need to do it. I've given up on Ulrich as he's never shown any interest in me and he's with Yumi. This way, I'll still be part of his family."

"He might need to if this keeps up," muttered Herb.

Harry's and Jeremy's Dorm

"Ok. Tell me what the good news is," said Aelita as everyone looked at her on the screen.

"Aelita, I don't know how to tell you this, but believe it or not…we're waiting for you here!" exclaimed a happy Jeremy.

"Really?!" asked Aelita in disbelief.

"Really!" exclaimed the others.

"The materialisation is going to work?"

"Yep. It's all in here," said Jeremy as he held up a disc. "And I can tell you it was really complicated! Defragmenting the intertial matrix wasn't enough, and so we had to start to recompile all the DNA correlations and-"

"Time out, Einstein!" interrupted Odd. Jeremy glared at him and Ulrich yawned.

"To make a long story short, it works," said Harry as Jeremy put the CD in a case.

"That's so great. Thank you. The both of you. I can't believe it."

"Better get used to it fast," said Odd. "Because it's time to take the big jump! And then it's bye-bye Xana!"

"We should still keep an eye out," said Harry. "Xana won't want to let the supercomputer be shut down."

"It's not that simple," said Jeremy. "We have to set up the program in the supercomputer first. Aelita will have to get to the passage tower in the forest as well before we can run it when she'll appear in the flesh for the first time."

"Well then. I guess I'm off to the forest for the last time."

"And we'll go to class," said Harry as he glanced at the time. "Afterwards, the factory."

"I'll see you later."

"We'll be six for dinner tonight!"

Lyoko

Aelita jumped into the data stream and landed in a tower in the forest sector.

Dorms

Jim walked into the building and up the stairs. Odd, Yumi Ulrich and Harry were waiting outside the dorm while Jeremy picked up a disc. They ran down the corridor where they were stopped by Jim.

"What's wrong? Up to no good again, aren't you?" asked Jim.

"No, we were just studying together!" exclaimed Odd. "That isn't unusual."

"And do you really think I'm up to no good?" asked a pouting Harry. "I am a good boy, you know. Never been in trouble."

"Studying, my foot!" said Jim as he pulled down his eyelid. "I've had enough of your lies! You hear? We're going to stay right here until you tell me the truth!"

"Jim? What is going on?" asked Delmas as he walked down the corridor.

"Ah, I'm glad you're here, sir!" said Jim to the principal. "I don't know what's going on, but these little devils are up to no good and I intend to find out what it is!"

"Yes, Jim, another one of your absurd stories about secret plots and passages?" asked Demas.

"What do you mean 'absurd'?" asked a confused Jim.

"You heard what I said. Absurd, Jim."

"But…"

"Now listen. Your paranoid behavior and your one track mind concerning these children are getting on my nerves. You're a PE teacher, not a detective!"

Jim hung his head as Delmas walked off down the corridor and through the double doors. Jim's face looked like he had rabies.

"What are you waiting for?" he yelled. "Get to class!"

Lyoko

"There it is," said Aelita as she saw the red tower in the forest region. "And Xana did have to activate it."

She hid behind a tree and looked at the monsters.

"Jeremy, I'm going to need help. There are too many of them too deal with on my own. Jeremy? Harry?"

Class

"Animals live in all land, sea and air regions," lectured Ms Hertz. "Thanks to their various respiratory organs."

"Hey, it won't be long now," whispered Odd to Jeremy.

"When animals and humans breathe, they take in oxygen and emit Carbon Dioxide," continued Ms Hertz as Jeremy sneaked a look at his laptop.

"What are you doing?" asked Odd.

"It's Aelita, she's in danger," whispered Jeremy as Ulrich looked over.

"Obviously, this phenomenon depends on certain factors. Who can tell us which ones? Jeremy? Go ahead, we're listening."

"Uh…the…the frog!"

The class laughed as Ms Hertz gained a bewildered look. The class ended as the bell rang. Odd and Ulrich ran down the corridor, avoiding the other students as Ulrich called Yumi.

"Yumi, come to the park. It's urgent."

"Sir, could I please go to the infirmary?" asked Yumi.

Outside

Harry, Jeremy, Odd and Ulrich ran past the pillar where Jim was hiding. He smiled and followed.

"Mind telling me what's going on?" asked Yumi as she caught up, slightly short of breath.

"Xana's at it again," said Jere3my shortly.

"He knows the end is near," said Odd. "And he's not going to go down without a fight."

Jim hid behind a tree. The five pulled up the manhole cover and slipped inside as Jim changed positions as he ran to a different bush. He ran over and looked around, confused. To him, it had looked like they'd just disappeared.

"Where'd they go?"

Sewers

They rode down the pathway and to the ladder which, as usual, they climbed up.

Lab

"Aelita? Can you hear me?" asked Jeremy as he sat down and put the microphone on.

"It's been such a long time," said Aelita. "I'm at the tower but there are lots of monsters. I don't think even Harry can handle them."

"It hasn't been more than one or two hours," said Harry. "I can handle a lot of monsters at once. You know that Aelita."

"Alright. Help is on the way. Once the way is clear, go to the centre of the tower."

The four ran down to the scanners.

"Who's going first?" asked Jeremy. Odd, Harry and Yumi walked in the scanners.

"Transfer Harry. Transfer Odd. Transfer Yumi. Scanner Harry. Scanner Odd. Scanner Yumi. Virtualisation! Your turn Ulrich. Transfer Ulrich. Scanner Ulrich. Virtualisation!"

Lyoko

"Ok Jeremy! We're here!" said Ulrich as they ran over to where Aelita was.

"Great. Get ready guys, I'm launching the materialisation program immediately!" He inserted the disk and pressed enter.

"Break! Break dance! Break! Break! Break dance! Break! Break! Break dance! Here we goooo-oooo-oo! Break! Break! Break dance! Break! Break! Break dance! Break! Break! Break dance! Here we goooo-ooo!" sang Odd on the clip along with animations of their classmates heads.

"Oh no…what have I done?!" asked Jeremy in horror as he watched the clip.

"Problem, Jeremie?" asked Yumi.

"I inserted the wrong CD! I have Odd's dumb videos instead of the program… STOP!" he ended the clip. "I've got to go back to the dorm and get the real disc."

"Ok but hurry!" said Harry as Jeremy left the lab.

Lyoko

"You made a video?" asked Ulrich as they waited at the tree.

"Well yeah, it's pretty good too!" said Odd proudly.

"What's the title?" asked Harry as he looked over at him.

"Break! Break! Break dance!" sang Odd.

"Ok, that's enough fooling around. We've got some cleaning up to do!" said Yumi as she walked over.

"SIR, yes, sir!" said Odd and Ulrich.

"Yes ma'am!" said Harry. Yumi glared at him which made him chuckle.

They ran out towards the monsters.

Kadic

"Ok, let's get started," said Jim as he put his foot on the ball. He was about to blow the whistle around his neck when he noticed Jeremy running. He frowned.

'This time I've got him,' he thought as he kicked the ball. "GO!"

Lyoko

The monsters started to fire at them. Harry quickly created several shurikens that could go through the shells of the Megatanks and threw them. The Megatanks exploded before they had much chance to do anything. Ulrich took out three Bloks and Odd took out a Krabe. Yumi destroyed three Kankrelats with one throw.

"This is too easy," said Odd as he landed on his feet.

"I agree," said Harry. "Xana knows that was more like a barricade made of paper for me."

"Aelita, get into the tower," ordered Yumi as the elf ran up.

"Wow, just think. This could be the last tower!" said Odd thoughtfully.

"In your dreams maybe, Odd," said Harry. "I wouldn't put it past Xana to do something that makes us keep the computer on."

Dorms

Jeremy ran up to the right door and opened it. He ran to the desk and picked up the right disc. He ran back out, closed the door and nearly bumped into Jim.

"Playing hooky, huh?" asked Jim with a smile.

"Uh, no. I left something in my room," said Jeremy as he backed up. "Uh I-I-I…I gotta go back to class now, Jim…"

"Not until you've told me what you've been plotting since the beginning of the year. And this time, the principal isn't here to come to your rescue!"

They had a short starting contest and Jeremy managed to get around Jim. He ran off and Jim followed.

"Why you miserable little brat!" Jeremy went around a corner.

"Get back here! When I get my hands on you…"

Jeremy ran down the stairs. He tripped, rolled and lay on his side.

"Jeremy! Oh no!" Jim ran down to him.

Jeremy tried to get up but fell down again. "My ankle!"

"Are you crazy Jim?" asked a nearby student as she helped Jeremy. "This is your fault."

Lyoko

"Jeremy, can you hear me?" asked Aelita. "We're in the tower. Jeremy? Where can he be?"

"I guess he got delayed," said Harry. "Do you want me to go check?"

"Forty five minutes is a long time to pick up a CD," said Ulrich. "I think Harry should check, like he said."

"See you in a while," said Harry as he exited the tower before stabbing himself with a sword and devirtualising. Just before his sight went dark, he saw a Megatank rolling up and he appeared in a scanner. He ran up to the lab and picked up the microphone. "Guys, there's a Megatank outside your tower!"

Odd, Yumi and Ulrich ran out of the tower and attacked it.

He started to hack into the school's cameras. "Too easy."

He looked around and saw Jeremy in the infirmary.

"Jeremy's hurt. That's why he's taking so long."

Infirmary

"Does it still hurt?" asked Yolanda as she wrapped up Jeremy's ankle.

"No, it's ok now. I can walk fine now."

"The one thing you'd better not do now is walk. You'll have to wait a week before putting that foot on the ground!"

"A week?!" asked Jeremy in disbelief.

"And if you complain, I won't give you crutches to get around with!"

Jeremy crossed his arms and huffed.

"This time, you've gone too far," said Delmas through the wall. "Don't say I didn't warn you. This time your paranoia has caused an accident."

"I'm sorry sir. I really am."

"So am I Jim. I'm going to have to let you go."

The words echoed through Jim's head and he imagined himself falling through ha crack in the ground.

"Can I go to the bathroom?" asked Jeremy as Yolanda put his foot on a rolled up blanket and collected some medicine.

"Sorry, the doctor insists you stay off your feet. I'll go and get you a basin."

Jim walked in as she left. Jeremy refused to look at him when he approached.

"Jeremy, listen I… I want to say I'm sorry. I was so sure you guys were up to something. I guess I got carried away a little." Jim stood up and walked to the window. "I deserve to get fired. I went a little crazy. I thought that you and your friends have a lot of secrets that you were hiding." He turned back to Jeremy and started towards the door. "I'm going to miss you guys."

"Hold on," said Jeremy. "You're not as crazy as you think. My friends and I… we do have a secret."

"But that means I was right after all," said Jim, leaning over Jeremy. "Let's hear it."

"Look Jim, if you help me, I'll tell the principal everything. You'll be off the hook. And he's bound to give you your job back, right?"

"Great." Jim held out his hand. "Shake on it."

They shook hands. Harry kept an eye on them but he didn't have sound.

Lyoko

The Megatank attempted to shoot Odd but it missed and Odd sent a laser arrow at it. It closed before the attack could hit. It reopened.

"You shouldn't have gone back to earth Harry," grumbled Ulrich.

"Not much I could do about it now," said Harry as he looked at the display.

Odd attempted to destroy it again but it reclosed.

Infirmary

"I have your basin," said Yolanda as she entered the room then stopped. The room was empty and the window had been opened.

Park

Jim was carrying Jeremy on his back through the park.

"Over there! Behind the oak tree," directed Jeremy. "Stop! In front of you!"

Jim looked at the manhole. He walked up to it.

"Haha, yeah! I was right! I was right! Eh? I was right, I was right!"

He opened the manhole and looked down it.

Factory

"And this super powerful thing called Xana that wants to destroy us," explained Jeremy as Jim made gun shapes with his hand as he walked around. "Only Harry and Aelita can deactivate the towers and Odd, Yumi and Ulrich help them to get to them."

"And Aelita lives on this place called uh, Loko?"

"No, it's Lyoko," corrected Jeremy as they went down in the elevator. "The only way to destroy Xana is to unplug the supercomputer. We have to materialise Aelita before we do that and that's what we're going to do today."

The blast doors opened to reveal the lab.

"Whoa… well what do you know?"

Jim helped Jeremy over to the computer.

"Harry, what are you doing back here?" asked Jeremy.

"We were wondering what was taking you such a long time," said Harry. "Ulrich, run up to it with your super sprint and stab it."

"Is everything ok?"

"There's a Megatank. It's trying to get to the tower, I think. What's Jim doing here? Has it got anything to do with the agreement you made with him?"

"Hey, you piece of junk! Nobody messes with my friends! Triangulate!" yelled Ulrich at the Megatank as he started to run in a triangle around the monster. Odd had just been devirtualised.

"Go on Ulrich, get 'im! Show this Xana thing who's the boss!" cheered Jim.

"Jeremy, Ulrich's…. Jim?"

"Yes, Jim," said Jeremy as he handed the disc over to Harry. "Don't worry, he's on our side."

Odd looked at him as Harry loaded the program onto the computer.

The Megatank managed to get rid of Ulrich's two clones but the real Ulrich managed to stab it.

"Ulrich! There's another one!"

Yumi ran over to it, dodged its shot and hit it.

"Nice one Yumi. Just a few more seconds…"

Harry was franticly typing away on the keyboard.

"How fast can he move?" asked Jim, staring at Harry's blurred fingers.

"I don't know," said Jeremy honestly. "I don't think he knows either."

"I'm nearly ready Aelita. Get into position."

Aelita walked over to the centre of the platform.

"Ok, well, ready to take the big jump?" asked Jeremy.

"Ready."

"Then here we go…," said Harry as he pressed the enter key. "Code Earth!"

Aelita rose up the tower just as Yumi and Ulrich got devirtualised by another Megatank. She stopped about half way up the tower and the blue files started to fly around as she disappeared.

Scanners

They all waited around the closed scanner as it whirred. It opened and smoke was released. Aelita was revealed to be at the bottom in the fetal position.

"She's here at last!" whispered Jeremy as she looked at them. "Welcome to Earth Aelita!"

Everyone cheered.

"Finally," said Harry in relief. "No more trips to Lyoko. Hopefully."
