I don't own Harry Potter or Code Lyoko

Unchartered Territory

An elf was running away from wolves, panting hard. She stopped as a larger wolf stood on a rock before running in a different direction as the pack followed. She stumbled and feel before getting back to her feet and continuing, slipping inside a tree. The pack surrounded it.

Aelita woke up screaming. She stood up and got out of bed.

Harry's and Jeremy's dorm

"Now let's see," said Jeremy as he printed out something. "Wow! Unbelievable!"

"Come on Jeremy, let's get a move on," said Ulrich as he, Odd and Harry stood in the doorway. "There won't be any hot water left."

"Remember the hermitage?" asked Jeremy as he looked at them.

"Where Aelita had these visions?" asked Ulrich. "I remember it."

"I wanted to check it out a little closer," said Jeremy as he turned back to the computer. "And I found out something amazing."

"What would be amazing would be if there was some eggs left at breakfast," said Odd.

"Odd, you're a real walking stomach, you know that?" asked Jeremy.

"And you're a walking brain!" retorted Odd. "You see? We complement each other!"

Jeremy glared at him.

"Stop annoying Jeremy Odd," said Harry. "He won't send you to Lyoko again. Talking about Lyoko, I added the ability to call your vehicles at any time. I also fixed the bugs."

"I did a little research as to who that house belonged to," continued Jeremy as they walked out the door. "And I came across a restricted access site. It took me most of the night to hack it but it was worth it."

"You should have just gotten me to hack," said Harry. "I could have done it in a fraction of the time."

"Be quiet you. I found a deed signed by a MR Franz Hopper. It seems that he's the owner."

Harry froze. "Franz… Hopper?"

"Yes, why?" asked Jeremy.

"My uncle Waldo took that name for some reason."

"Do you think it has something to do with Lyoko?" asked Ulrich.

"Possibly," said Harry. "I only got up to the part in Mum's diary where he informed her he was changing his name."

"It's got to," said Odd. "There is a secret underground passage to the sewers to his yard, remember. The guy had to have something to do with the supercomputer."

"Exactly," said Jeremy. "So I did a search on Franz Hopper. Guess what? He was a science teacher right here at Kadic. Weird or what?"

"I'm going to see Aelita," said Harry as he headed to the girl's dorm. "I already had a shower since I was up all night."

Aelita

Aelita went to the back of the long queue that had formed. Sissi walked out of the room.

"Finally, it's about time."

"Things might start moving now that Sissi's done," said Tamiya.

"Shut up Kiddies"

They stuck their tongues out at her.

"Poor thing. You'll be here for another two hours," said Sissi to Aelita. "There's some showers free upstairs."

"Leave her alone Sissi," said Harry as he opened the door. Everyone except Aelita looked at him with hearts in their eyes. "Those are the boy's showers and you know it."

"Well, Miss Einstein, not a single girl in those showers."

"What's happening?" sked Jim. "What are you doing here Harry?"

"I'm checking on Aelita," said Harry. "Sissi was about to send her up to the boy's showers. I stopped her."

"Well then carry on. "

"Sissi, I'm tired of your bad jokes. You knew Aelita would believe you," said Harry.

"What can I say?" asked Sissi. "Harry sweetie, she's going to have to adapt, isn't she? It's a jungle out there!"

"You can say that again! I'm looking at someone who might like it there!" said Harry. "Someone who likes to tease the new kids."

Odd and Ulrich laughed as they passed by the door.

"Sissi's such a brat! And to think that Harry and Sissi actually kissed once!" said Odd.

"Hey, cool it, huh? That's ancient history."

Later

"So you think the owner of the Hermitage and the science teacher are the same person?" asked Yumi. "And that he's really Harry's uncle Waldo."

"Well, let's face it, huh? Finding two guys called Franz Hopper in a radius of less than half a mile would sure be a real coincidence," said Ulrich.

"Anyway, there's only one way to be sure," said Jeremy. "After physics, we have a study period in the library. We can research in the Kadic archives then."

"Good idea," said Odd.

"I'll go with you," said Aelita. "Thanks for helping me out earlier Harry."

"No problem," Said Harry. "Just try to ignore anything Sissi says. Unless she's talking about a Xana attack. Then you listen. About the archives, it's best to let me go. I can do it quicker and make sure nobody sees me."

The bell rang. The boys moved off and Harry waited for Aelita.

"Are you alright, Aelita?" asked Yumi.

"Uh…I can't get used to living here…I had another nightmare last night. The same one," said Aelita.

"You haven't even been here for a week yet. You'll see, you'll feel better in no time," said Yumi. "Look, Harry's waiting for you."

Aelita smiled and walked over and the two headed to class.

Later

Harry and Jeremy slipped into the archives. Harry faded out of view and a faint breeze appeared as Jeremy started on the first row of files.

"Oh, shoot!" said Ulrich as he and Odd smile stupidly at Ms Weber.

"Shouldn't you be in class? Well, children?"

"We're looking for um…uh, a teacher!" Ulrich used as an excuse.

"Oh, really? Which one?"

"Ms Meyer!" said Ulrich at the same time as Odd.

"Mr Chardin!" said Odd at the same time as Ulrich.

"Found it," whispered Harry as he picked up the file and opened it. "What do you want Jeremy?"

Jeremy compared the signatures. They were the same. "What do you know?"

"Uh, come to think of it, at this time of day if you can't find your teachers it probably means they're in class," said Ms Weber.

"It's ok, guys! I found Ms Hertz!" said Jermyn then turned to Ms Weber. "Ma'am!"

Ms Weber rolled her eyes as Harry ran back to Aelita at full speed.

"What was that?" asked Ms Weber.

Lunch

Aelita stood at the serving area.

"What are you waiting for?" asked a boy. She looked at him and put her tray on the metal and moved along. She looked at the meals

"Hey, can you move it!"

"Leave her alone," said Harry as he walked over. "There's no time limit."

The boys shut up as they didn't want to annoy him. Harry wouldn't do anything blatant but recently, anyone who annoyed him got hurt. Nothing more than a scrape though.

Aelita smiled and picked up a plate. She moved up.

"Steak and potatoes?"

"Yes please."

The dinner lady placed it on her tray and Aelita moved away.

"Thank you Harry," said Aelita.

"It's no problem. It's always like that," said Harry.

Outside

"About time," said Ulrich. "Where did Harry go? I take it that the breeze was him."

"I guess he went to see Aelita," said Jeremy. "You know how he protects her like an older brother. Anyway, I compared the signature with the one on the internet. They were the same."

"How about we look around the heritage?" suggested Ulrich. "Find out more about Franz or Waldo or whatever his name is."

"Good idea."

"Aren't we meant to meet with Aelita in the cafeteria?" asked Odd.

"It will take a minute. Harry's there so…"

Cafeteria

Aelita looked round as Harry ate his food.

"Yumi!" Yumi sat down near William. Aelita sighed and walked out.

"So! Going back to the great white north?" asked Sissi meanly.

"Why not? At least I feel at home there!" Aelita yelled as she ran off.

"Aelita! Aelita!" Harry shouted after her. "We'll talk about this later Sissi."

Harry ran after her. 'I guess she's having a really hard time adapting,' he thought.

Hermitage

"Still looks as creepy as ever…what are we looking for?" asked Ulrich as they looked at the ruined house.

"How should I know?" retorted Jeremy. "If Franz Hopper has anything to do with Xana, this is the best place to look for information about Aelita's virus."

They found a collection of books.

"What have you found?" asked Ulrich.

"A collection of physics text books. Frank, Heisenberg, Schrodinger… what's this doing here?" Jeremy pulled out a book form the shelves.

"The Tunic Wars? What's that?" asked Ulrich as he read the title.

"Punic, not Tunic! The war between the Romans and the Carthaginians. We studied it last year, don't you remember anything?" asked an exasperated Jeremy.

"Vaguely."

"You are lame in history," said Odd as Jeremy opened it.

"You see all these notes?" asked Jeremy. "I'm sure Hopper wrote them."

Lab

"Aelita!" Harry ran up to her as she was just about to activate the delayed virtualisation program.

"I'm going to Lyoko. Don't stop me."

Harry sighed. "I'll come with you then."

Aelita added his ID card and they went to the scanners.

Class

"Where's Aelita Stones?" asked Ms Hertz. "And Harry Stern? Jeremy, do you know why they aren't here?"

"Aelita and Harry?" asked a surprised Jeremy. He looked around. "Sorry Ma'am, I don't."

"Well I do, ma'am! She went back to Canada! And Harry followed her!" called out Sissi.

"Canada?!" asked Jeremy.

"Yeah, that's what she told me! She even said "At least I feel at home there"! Harry ran after her to talk to her, I think."

"Elisabeth, if you continue to disrupt the class, I will send you to your father's office."

"It's Sissi! Not Elisabeth. I hate being called Elisabeth."

"Ma'am…uh…I don't feel very well. Can I please go to the infirmary?" asked Jeremy.

"Of course, Jeremy," said Ms Hertz.

"Can we take him?" asked Odd and Ulrich.

"Well…oh…oh…" said Ms Hertz as the three boys got up without looking at the teacher." …alright then. But don't dilly-dally!"

"Hey Jeremy, wait!" called Odd as Jeremy ran down the corridor.

"Where are you doing?" asked Ulrich.

"To the factory!" called back Jeremy.

"You think Aelita and Harry are there?" asked Odd as they followed them.

"She told Sissi she was going back to Canada. I think she meant "I'm going back to the place I came from," which means Lyoko! Sissi also said that Harry followed her. That means he's with her! Aelita can't outrun Harry. Not unless Harry lets her of course."

Lyoko

The two walked down a path in the forest sector.

"You know that you didn't have to react like that," said Harry.

"Sissi was getting to me. How do you do it?" asked Aelita. "Bear with it I mean."

"I guess, since I grew up on Earth, I got used to how people like Sissi work," said Harry. "I also developed ways of dealing with them."

A Blok appeared in front of them as Harry threw a shuriken.

"Didn't you want another ride?" asked Harry as he pulled up a holographic screen and selected a 2d image of the Overjet. It appeared in front of them and Harry climbed in. "Coming? It gives me chance to test it in the forest sector."

Aelita smiled and jumped in the second seat.

Lab

Jeremy ran into the lab.

"Ok, I found them. They're in the forest sector… and Harry's giving her a ride."

"Why did they do that?" asked Odd.

"Maybe Aelita got homesick and Harry's trying to cheer her up," said Ulrich. "Aelita did like the ride in the Overjet."

"Does Yumi know?" asked Jeremy.

"I left her a message," replied Ulrich.

"Get to the scanners." Odd pressed the button to go down.

Lyoko

Harry landed at the edge of the sector and they hopped off. Harry dismissed the Overjet.

"Harry? Aelita? Can you hear me?" asked Jeremy.

"Yeah, we hear you," said Harry as he destroyed several Krabes that Xana had just sent.

"What's up?" asked Yumi as she dried her hair. "I got the message at the swimming pool."

"Tell you later," said Jeremy. "Get to the scanners. Odd and Ulrich are already there."

Yumi went down.

"Jeremy, hurry up," said Harry as more monsters appeared. "I know I can handle this but we're right at the edge of Lyoko."

"Don't worry," said Jeremy. "The others are on their way. Transfer Ulrich. Transfer Odd. Transfer Yumi. Scanner Ulrich. Scanner Odd. Scanner Yumi. Virtualisation! Do you see them?"

"Nope," said Ulrich.

"They're due north!"

The three ran up the path.

"Oh great, more monsters," sighed Harry as he faced two tarantulas. Aelita backed up at the same time Harry did as he shot them in the nose.

"Go ahead, Ulrich! With your speed you'll get there first!" said Odd.

"You're right…" said Ulrich.

"Too late!" said Yumi as they stopped. She pointed at a Krabe.

"There's another one behind you!"

"Alright. Battle stations," said Ulrich. "Your move, Odd!"

"I love this!"

Odd dodged the laser fire and climbed a tree. He shot at the Krabe and destroyed it. Ulrich cut the legs off the other Krabe and Yumi destroyed it with her fan.

"Nice going guys," said Jeremy. "But hurry up. Harry is surrounded by monsters."

"I can deal with it," said Harry as all the icons representing monsters disappeared form the screen.

"What are you waiting for? Call us a taxi!" said Odd.

"It's on the way!" said Jeremy. "When you see Harry, remind him to tell you how to call your vehicles."

The three vehicles appeared in front of them.

"Here we go!" said Odd as they moved.

A ball with the eye of Xana appeared behind Harry and Aelita as they stood at the very edge. It engulfed them. Aelita screamed.

"Aelita! Harry!"

The three arrived.

"What? She's already gone?" asked Odd. "They must really be mad at us!"

"This is no time for jokes, Odd!" said Jeremy. "I've lost Aelita and Harry from my screens!"

"You…you mean…they are…"

"No! I…I doubt it. I think she's just…disappeared from the screens as if…" said a panicking Jeremy. "Wait! What's going on?" Jeremy typed at the keyboard. "I got a signal from both of them. It's weak but they're there alright. Hey, that's strange…Aelita and Harry aren't in this Sector anymore. They're not in any Sector, actually!

"W-wait, can you explain that a little better?" asked a confused Ulrich.

"No, not really! Let's just say they're in a Sector…that doesn't exist…a fifth Sector!" exclaimed Jeremy.

"Huh? A fifth Sector? Have you gone bananas or what?" asked Odd.

"No… if we could just fix this thing… what the…" files started to move around and the computer asked for a password. "Welcome to Carthage?"

Sector 5

Aelita and Harry started to wake up.

"What happened?" asked Harry as they stood up and looked around. A pathway opened up and they walked through it. "What is this place… a fifth sector? Let's be careful."

Forest sector

"IS this going to take long?" asked Yumi.

"I hope not," said Jeremy.

"Uh-oh, now things are really starting to buzz! Said Odd as he saw hornets and jumped on the Overboard. Yumi destroyed three on the Overwing and Ulrich jumped of the Overbike using Super sprint and destroyed a hornet.

"Jeremie, what are we doing?" sked Ulrich as he landed back on the Overbike.

"Wait, I've got a little problem!" said Jeremy. "If only Harry was here…"

"That's no biggie! As long as it's not a biggie…" said Odd.

"I need a password…something to do with Carthage I think!" said Jeremy.

"This is no time for a history lesson!" exclaimed Ulrich.

"A history lesson! That's exactly what I need!" said Jeremy as he stood up and took the Punic Wars book from his bag. "That's too easy."

Ulrich destroyed two more Hornets and got knocked off the Overbike. Odd destroyed another Hornet.

"Hey Jeremie…any day now!" called Ulrich as Jeremy entered words.

Sector 5

"What's going on?" wondered Aelita as they walked up to a wall. It separated and they moved onwards.

"This place is different," said Harry. "I guess it's kinda like the centre of Lyoko. I wonder if what holds Lyoko together is here…"

They ran into another monster.

"First the tarantulas no this," complained Harry as he sent a homing shuriken at it and it blew up. "Are we going to run into any more new monsters?"

Lab

"Enemy of Carthage…" muttered Jeremy as he entered Rome. "No dice."

"Whenever you're ready Einstein!" called Odd.

"Hey, you guys, I'm doing my best!" said Jeremy as Odd was chased by a hornet.

"We're not going to last much longer," said Yumi as the Overwing was destroyed. More hornets turned up. "I can't believe this."

"I'm going around in circles! "Welcome to Carthage"! Let's see…you've gotta go into Carthage…you have to defeat Carthage! Who defeated the Carthaginians? …Scipio!" the computer accepted the password. "I can't believe it."

"Hey, the Hornets are calling it quits!" said Yumi.

"Come back, you cowards!" called Odd as the ball came up.

"What's that ball doing there?" asked Ulrich as he saw it.

"I think the code word Scipio made it appear," said Jeremy as it spun around them and scooped them up before traveling along the forest sector, into a bright light were wires went in and through a field of files where a ball with four blocked tunnels appeared. They entered it and ended up where Harry and Aelita woke up. The ball released them and disappeared.

"How did you do that, Jeremy?" asked Ulrich.

"Let's just say I got a little help from Franz Hopper! Welcome to Sector Five, everyone," said Jeremy.

"What does it look like?" asked Yumi.

"A sphere." A timer turned up. "It's probably bad news."

Aelita and Harry ran through another passageway and ran into a few more of the new monsters. Aelita hit a few with her energy fields as they heard a strange noise.

"Not another monster," complained Harry as he destroyed another monster. They backed off as two Jellyfish like monsters entered the room.

"Run!"

Harry pulled Aelita onto his back and ran as fast as he could. The two monsters followed.

"I think Aelita's being attacked, and time is almost up!" said Jeremy as he looked at the screen.

"Can you guide us?" asked Yumi.

"Take the footbridge behind you, hurry up! This is no time for sight-seeing!" ordered Jeremy.

Harry stopped as he saw a field of monsters. "Aelita, keep an eye out for those two Jelly fish. I think they're here for us. I'll deal with this."

He started throwing shuriken left and right as Aelita prepared two energy fields. One of the jellyfish came in and Aelita threw them at tit. It dodged and picked her up with its tentacles. Three more tentacles touched her head and started to absorb something from her.

"Aelita!" Harry destroyed the last of the monsters and threw a shuriken at its head.

"What's going on?" asked Jeremy as a display showing Aelita and a number going down appeared.

"Jeremy!" called Harry as he threw more shuriken at it. "There's this monster here! It looks like a jellyfish and it's doing something to Aelita. There's another one around and I think it's looking for me."

"Uh…Jeremie…there's this…thing in here…" said Ulrich as he entered and looked at it. It dropped Aelita as Harry hit it.

"Destroy it! It's taking Aelita's memory!"

"Oh great, here's the other one," said Harry as it grabbed him. The same thing happened to him. "NO!" It dropped him and Harry shook his head. His mind felt much clearer.

"Get out of there!" yelled Jeremy as the room started to rearrange. They ran as the walls began to shut. They managed to make it out in time as Odd just cleared it.

"Just in time!" said Jeremy as they ran into the middle of the structure. Aelita collapsed.

"Now what?" asked Ulrich.

"I'm re-entering the code."

"We've got your ticket out of here, Aelita and Harry!" said Odd as the ball picked them up and took them back to the forest. It placed them next to a tower.

"There you go. I'm bringing you in right now," said Jeremy. "Aelita, there's a tower you can use for materialisation!"

Aelita entered the tower.

"Materialisation Yumi. Materialisation Odd. Materialisation Ulrich." Jeremy waited for a minute. "Materialisation Harry. Code Earth!"

Harry's and Jeremy's Dorm

"You should've seen it, Jeremy! There were all these creepy things, and in the middle this kind of huge jellyfish holding Aelita!" said Odd as Kiwi growled.

"Can you imagine that thing was stealing my memory?" asked Aelita.

"And mine," said Harry. "My head feels a lot clearer. what are we going to call them anyway?"

"It wasn't stealing your memory Harry," said Jeremy. "It was doing something else. Take a look. as for the names, Schyphozoa for the Jellyfish."

Harry looked at the computer record of what happened.

"It looks like it was… preparing me for something. It's not such a mess. And I think Creepers for the creepy monsters."

"One's thing for sure," said Jeremy. "Xana wants something form you two but I don't know why. We have to find out."

Harry froze. "I have just had a rather nasty thought."

"What?" asked Jeremy.

"If Xana can take things out of us using those jellyfish, what's to stop him putting something in? Like, say, his programming," said Harry.

"That is a bad thought," said Jeremy. "He could easily take control of you through that."

"I can't wait to go back to the fifth Sector. There's so much to explore there!" said Ulrich.

"I'll go with you. It'll be totally awesome," said Yumi.

"It might let me find out what Xana wants form me and Aelita…" Harry froze again. "Wait, there's a program me and Aelita share. Xana might want the copies of that."

"Whoa, not so fast! I have to study it first! For now, it's unchartered territory! Which means it can be totally dangerous!" said Jeremy "As for what you said Harry, well it's a possibility."

"You're not angry at us for going to Lyoko, are you?" asked Aelita. "I don't know what got into me."

"You don't have to explain Aelita," said Jeremy. "We understand what happened. And we're not angry at all. We do have Harry rot thank for keeping you as safe as he could."

Harry blushed.

"I promise to spend more time with you," said Jeremy. "After all, we can't rely on Harry all the time to keep you safe from Sissi."

"And if you want, I'll teach you plenty of ways to tell Sissi to go to…" said Odd.

"Odd!"

"Huh?"

"Do you know what your filthy mutt did in the shower?" asked Sissi as she saw Aelita. "Oh! What a pretty picture! So you finally found Mrs Einstein!"

"Yeah, while you were taking your third shower of the day!" said Ulrich.

"Hmph, well you know, Ulrich, a beautiful flower like me needs to be watered often!" said Sissi.

"You!" said an angry Odd.

"Yes, you never know; you might just sprout a brain!" said Aelita. Odd, Yumi, Ulrich, Harry and Jeremy laughed.

"Morons!"

"I think you can give Odd lessons, Aelita!" said Ulrich as they walked outside. Harry looked around and groaned. "Not you three again. Dumbledore, Ronald boneheaded Weasel and Hermione the bookworm Granger."

The students glared at him.

"Harry, I have gotten permission from the ICW to take you back to England, place you with the Dursleys and for you to come to Hogwarts," said Dumbledore.

"Have you talked to the normal government?" asked Harry.

"No. I don't need to," said Dumbledore arrogantly.

"Well then. If you take me, I'll go to the French embassy in London and tell them that I'm a French citizen who has been brought to England against his will," said Harry. "That's why I also keep my passport on me. Also, do you have proof of this?"

Dumbledore started as he had just made that up. The ICW refused to remove him from France as he was registered as a French citizen, not an English one as he had lived there most of his life.

"Harry mate," said Ron. "You need to learn how to use magic and you get a wand."

Harry raised an eyebrow and pulled out his wand.

"You do now it's illegal for us to do magic in front of muggles?" asked Dumbledore.

Harry shrugged. "I got permission from the government to do it in front of Jeremy Belpois, Ulrich Stern, Yumi Ishiyama, Odd Della Robbia and Aelita Stones. It's because apparently I did everyone a great service when I defeated Voldemort as he threatened everyone as he would have come to other countries once he had done in England. This was their way of repayment. Obliviate!"

He erased their memories and sent them back to Hogwarts.

"That's how you get rid of him," said Harry proudly. Everyone laughed.
