I don't own Harry Potter or Code Lyoko.

Routine

Three Bloks and a Megatank waited in front of the tower.

"It's now or never!" said Jeremy. The croup separated with Odd and Harry going for the monsters and Aelita and Yumi taking the scenic route. Yumi used her fan to destroy one of the Bloks and Harry dispatched the other two.

"Go on Aelita, go!" said Ulrich as he defended Yumi. Aelita ran to the tower.

"Come and get me, you bowling ball!" Odd called to the Megatank as he aimed. The Megatank split in two charged up its laser. Odd dodged the shot and jumped on it, defeating it with a single arrow.

Aelita entered the tower. She walked up to the screen and pressed her hand to it.

"As usual, guys; great job!"

"That's right…another Xana attack chopped up, another tower gone!" exclaimed Odd.

"Get ready for the trip to the past."

The light erased the events.

Earlier

"Well guys, how was class today? With Ms Hertz? Was it fun?" asked Yumi as she met up with the rest of the group after the return to the past.

"Oh, the same exact lesson as before the Xana attack, so it was twice as boring," said Ulrich.

"Once, twice, it doesn't matter; you'll never be any good in physics anyway!" exclaimed Jeremy.

"I just see it as a chance to revise the lesson," said Harry.

"Well if it isn't Sissi…," said Odd as he spotted her before starting to imitate her. "Hello, Ulrich deeear! Caaan we talk for a miiinuuute?"

"Hello, Ulrich dear! Caaan we talk for a miiinuuute?" asked Sissi, repeating the same words for the first time. Well for her anyway.

"Hehehehe!"

Sissi glanced at him before looking at Ulrich.

"First of all, I'm not your "Ulrich dear," second of all I will not go to your room to explain exercise B page 52,"said Ulrich.

"But…how did you know that I…? Ugh! How about you Harry?"

"I don't really want to go to your room Sissi," said Harry. Sissi stalked off.

"A Sissi attack is almost as bad as a Xana attack, and ten times more boring!" said Yumi.

"That's for sure…" muttered Ulrich as he stared into space.

Later

"So, anyone feel like sneaking out and going into town for a while?" asked Ulrich.

"Count me out, I've got a heavy date with my pillow! Ha!" said Odd.

"How unsurprising," muttered Harry as he marked his place in the diary.

"And I'm going to work on my program for materialising Aelita! One of these days I'm going to do it!" said Jeremy.

"How about you, Yumi? Want to go into town and have an ice-cream?" asked Ulrich.

"No, not tonight, I've got to do a little studying…I'm way behind thanks to all these Xana attacks. See you tomorrow!"

"See you!"

Ulrich slumped his shoulders as he watched her go.

"Hey, don't be miserable Ulrich," said Harry as he pulled a few items out of his bag. "She still loves you but you have to do things apart as well. I'll go out into town with you if you want me to."

"Thanks Harry."

The two walked out the gate and ran down the street. Harry led Ulrich to a blank stretch of wall.

"Uh, where are you going?" asked Ulrich. "And why do you have a stick?"

"I thought you'd like to see the magical street," said Harry. "And this isn't a stick, it's a wand."

"When did you get the wand? And how did you find this place if you didn't have a wand?" asked Ulrich as Harry tapped the right bricks in the right sequence and the passageway opened up.

"Well, remember when I said I was famous?" Ulrich nodded as they walked down the passage. "A witch recognised me and let me in."

They reached the end and Ulrich stared at the many brightly coloured shops.

"All this is hidden in a tiny alley?"

"Yep. Magic is awesome, isn't it?"

"You're right there."

"I'll need to get some money pout but after that, we can go shopping," said Harry early as he dragged Ulrich along.

"What kind of shopping?" asked Ulrich into the wind.

"Any type!"

Once Harry had visited the bank, the two boys went around the shops. Harry got the next set of books for the year, Ulrich bought some sweets and a protective charm. Harry looked at him.

"It's for Yumi."

Later

"You ought to take a shower! It really relaxes you!" said Odd as Ulrich and Harry walked in with Ulrich's shopping.

"Tell me what your day was like," said Ulrich as he and Harry sat down on the bed. "And why would I want to relax?"

"Oh, nothing special, let's see now…I had the embarrassment of my life in gym class. My shorts tore, you can guess where. Then I lose my pencil case in the library, and to finish the day I had a fight with Marcy… Aaand that's what my day was like! As for why you'd want to relax, well, you've been rather stressed lately."

"But what I mean, Odd, is…don't you feel you've already had the same exact kind of day?" asked Ulrich.

"Well yeah, but that's normal! Don't forget we had the same French, English and physics class twice! And on Lyoko is was "yoohoo, it's us!" for the seventh time."

"Yoohoo it's us"?" asked a confused Ulrich. Harry listened in.

"That's what I call our game plan, you know, the one we use to help Aelita and Harry to reach the tower safe and sound. Why all these questions, hm?"

"No reason, I've…I'm fed up with all this school, Lyoko, back to school, back to Lyoko, and uh…this is XANA's fifth attack in a week!" said a mopey Ulrich.

"Tell me about it," said Harry. "The near constant headaches are getting to me. Xana is a lot more active than usual but he isn't going to keep up the near constant attacks forever. If you want to change the routine, then change it."

"And I occasionally have this feeling about Yumi, like she doesn't really like me."

Harry sighed. "The only thing I can do there is suggest that you talk to her. It could be just a misinterpretation. Every relationship has its problems."

Odd snored.

"I guess it's time for me to go," said Harry as he stood up. "I'll see you tomorrow, assuming Xana doesn't attack in the night."

"See you Harry." Harry ad Ulrich walked out and separated. Harry went to his dorm and Ulrich went to the showers. On the way back he saw Emily but thought nothing of her apart than she was pretty.

"Hi Emily."

"Hi Ulrich. I'm looking for Jim. Have you seen him?"

"No sorry."

"It's ok. Good night."

They continued walking down the corridor and Ulrich entered his dorm.

Factory

The supercomputer rose form it's covering. The monitor several floors above showed it connecting to Lyoko without anyone at the controls.

The next day

Yumi walked into school where Ulrich was waiting for her.

"Hey Yumi. Can we talk?"

"Yeah, sure. What about?" asked Yumi as they walked towards the building.

"It's probably nothing but recently, I've been having this strange feeling."

"What kind of strange feeling?"

"Well, as I said, it's probably because of nothing but I have this feeling that you don't like me."

Yumi sighed and kissed him. "You're an idiot. I won't stop liking you. I know I haven't spent much time around you recently but that doesn't mean I've stopped liking you."

They walked over to Jeremy Harry and Odd who were sitting on a bench.

"I see you've cheered up Ulrich," said Harry. "I see you've talked to Yumi."

"That reminds me." Ulrich pulled out a box and gave it to Yumi. "This is for you."

"Thank you." Yumi took the box and put it into her bag.

"Aren't you going to open it?" asked Ulrich, confused.

"In Japan, people don't open gifts in front of the person that gave it to them," said Harry.

"That's right," said Yumi. "I see you've been doing your research Harry."

"I was bored and had nothing to do. I do have a book on magical Japan if you want to read it. Oh, and before I forget it, a certain you know who has activated again."

Everyone groaned.

"I think he's messing up the supercomputer." Jeremy froze.

"That could be serious Harry."

"Jeremy! Xana's launched another attack!" said Aelita as Jeremy opened up the laptop.

"Are you feeling pulsations?" asked Jeremy.

"In the desert. They're really strong."

"I've never seen him as active as he is now," said Jeremy thoughtfully.

"It's kinda strange for him," said Harry. "I mean, he used to attack once every few weeks."

The bell rang.

"And there goes the bell," groaned Harry as the students started to move.

"It will be alright. We'll go back in time," said Jeremy. "Sorry but you'll have to go over again."

"Well, when you've got to go, you've got to go," said Odd. They started to head over to the manhole when Sissi walked up.

"How's Emily Ulrich?" she asked. "You've been going out with her for what now? Two months?"

Yumi glanced at Ulrich who faceplamed.

"Sissi, I hardly talk to her and I've never been out with her. The last time we talked, it was about if I had seen Jim. Stop trying to cause trouble."

Sissi stormed off in a strop. The group started off again.

Lab

Jeremy checked the computer. "Everything's quiet here. No short circuits, no giant bugs, no earthquakes, no nothing. Harry, you can see what Xana's up to, can't you? And you Aelita?"

Harry nodded and concentrated for a minute. "I'm still getting the image of the supercomputer. Xana might be trying to lead us into a trap so…" He leaned over and checked some programs. "Nothing wrong with the virtualisation modules or the return to the past. I can't access the devirtualisation programs which is odd. Jeremy, when we go over, will you check them for me?"

"Of course."

"I'm nearly at the activated tower," said Aelita. "Xana's monsters haven't appeared yet. If not for the pulsations, there's no sign that anything is wrong."

"That's odd as well," muttered Harry. "Xana's definitely up to something."

"I wonder if Xana is trying a new tactic…"

"The attack could be aimed at us directly?" offered Odd as a theory.

"He could be using your ridiculous theory as an attack," said Ulrich, sore over the suggestion that Sissi had made.

"Don't mind him, he's being a grump," said Harry.

"I think you should do a little reconnaissance on Lyoko," said Jeremy. "Who wants to be first?"

There was silence.

"Don't all speak up at once..."

"I'll go over first," said Harry as he walked over to the elevator.

"Man, Harry is always eager to go over isn't he?" Odd asked no one in particular.

"Alright then." Jeremy waited for a minute. "Transfer Harry. Scanner Harry. Virtualisation! Now, who's next?"

There was more silence.

"For that, you're all going. Get down to the scanners."

They walked slowly out.

"Transfer Odd. Transfer Ulrich. Transfer Yumi. Scanner Odd. Scanner Ulrich. Scanner Yumi. Virtualisation!"

An error sign appeared on everyone's except Harry's ID card on the computer.

"Uh oh!"

Lyoko

Harry watched as the three fell down.

"Hi," said Aelita as they looked around the desert.

"This place is too hot!" exclaimed Harry. "Has Xana turned up the heat?"

"Hey, guys," said Jeremy. "There was a bug in the moment of transfer. It didn't happen to Harry. Did they make it over there?"

"Head count" called Harry as he quickly counted everyone. "Five people here Jeremy!"

"That's a relief."

Harry froze. "I thing I know why there was a bug Jeremy. Remember, I couldn't gain access to the devirtualisation programs. It could have been because of Xana."

"Could you have gotten in there?" asked Jeremy.

"Given time, yes. The security was tight but no system is folkloric."

"I'll scan the program to see what happened." Jeremy typed away as he started the scan. "What is this mess? I think the supercaculator has been infected with a virus. So that was the Xana attack."

"I was right," said Harry as they slid down a slope. "The attack did have something to do with the supercomputer."

"That's crazy," said Odd. "Why would Xana want to infect himself? He does depend on the computer to survive after all."

"Xana's a psycho," said Harry as they walked onwards. "His reasons are likely weird and obscure and we won't be able to understand them until he's attacking."

"You never know what Xana's got in his head until he's done," agreed Jeremy.

"He might be using the virus to modify a program he doesn't have access to," suggested Aelita.

"Does Xana have access to the virtualisation and devirtualisation programs?" asked Harry. "He wants to change the rules on Lyoko."

"No. Why do you….. Xana's affecting them!"

"I have a funny feeling about this," said Ulrich.

"We need to take a closer look at this," said Jeremy. "There has to be a deactivated tower around."

"I'll go have a look," said Harry as he ran off. Ulrich sniggered.

"That's Harry. Always eager to look at programs."

The four walked in the direction Harry went in as they waited for Harry to reappear.

A Kankrelat arrived and started to follow them.

"You go Odd, you're the closest…" said Ulrich lazily.

Harry

The ninja entered the deactivated tower and went to the screen. He fiddled around in the systems and found the transfer program.

"Jeremy, I'm looking at the program. It's strange. I was right. Xana had messed up the program as it usually doesn't include Xana's monsters. It's a trap. He sabotaged the devirtualisation programs, like I said he did."

He jumped out of the tower and ran back to the group.

Ulrich

Odd walked up to the monster and aimed at it.

"Odd, watch out for lasers! This monster could kill you for good! Xana's monsters can prove fatal to you!" warned Jeremie as he understood what the system bugs could do.

Odd destroyed the monster but got hit.

"What's the problem Jeremy?" asked Ulrich.

"You can't be devirtualised or you'll disappear forever!"

"Good thing he didn't get me," said Harry as he reappeared. "Let me take care of the monsters."

"Odd's lost fifty life points already!" yelled a panicking Jeremy.

"Calm down Jeremy. Odd's still here," said Harry. "Do you want me to go back to Earth or do you want me to stay here?"

"Stay there Harry. And you don't understand. Odd got hit by a laser."

Listen Jeremy. Aelita takes the same risks all the time. We just have to be more careful as we escort her or Harry to the tower," interrupted Ulrich as they looked around.

"One thing is sure; Xana's really trapped us," said Yumi. "And we'd better not make a mistake this time."

"It'll make the fight a lot more exciting!" said Odd enthusiastically as he stood back up.

"We need to deactivate the tower," said Harry as Krabes turned up and he started to destroy them. "Before Xana can concentrate his energy on us."

"That's the safest bet," said Jeremy. "Let Harry do all the work. He's not affected by the bug so he'll be devirtualised normally. Watch out for monsters."

The quintet started to walk towards the tower.

"I'll try to get rid of the virus," continued Jeremy as he worked on the computer. "Listen, Xana, if you think you can impress me with your cheap, two-bit virus, you are mistaken! I'm never going to get it to work! Phooh… Xana has completely wrecked the circuits! There's only one possible solution. Work directly on the hardware!"

"Hurry up!" called Harry as he cut through another set of Krabes. Jeremy went down to the scanners.

Scanners

"There has to be an access somewhere," Jeremy muttered as he looked at several displays. "Must be in the supercaculator room."

He turned round as the doors locked. "Xana, you are even more evil than I thought. Of course. The access bays. If I adjust the winch, I'd be able to get down."

Jeremy quickly set up the equipment and started to lower himself down to the computer.

"You don't scare me Xana. I just have to replace the circuit boards you messed up."

He started removing the damaged circuits and replacing them.

"You'll fail again, like all the other times!"

Lyoko

"Jeremy, how are you doing?" asked Aelita as they ran across the desert. "Jeremy?"

"Hey, look, it's the tower," said Harry as he pointed at it. "Jeremy is trying to sort out the hardware."

"It's all over," groaned Yumi as they looked at the twenty monsters in front of them. "If we try to get through all this, we're done for."

"You never know…we just have to hang on until Aelita or Harry enters the code," said Ulrich. "Most likely Harry."

"It's yoohoo it's us time!"

"Yumi, you take the Krabes... Harry!"

"What?" asked Harry as he looked confused. "You can't be devirtualised without dying so I took out the monsters for you."

Ulrich shook his head.

Several more monsters turned up. Harry sighed and started to throw his shuriken.

Supercomputer

"Bingo! You were just-" said Jeremy as he pushed in the circuit boards before getting an electric shock "aaaaaaaaaaaaah!"

He got launched up really quickly, dropped back down and was winched back up.

Lyoko

Harry sighed once the fifth batch of monsters were destroyed. He glanced at the rest of the group. Yumi had nearly got knocked off the paths but Ulrich had caught her. It looked like they were going to kiss.

Harry entered the tower and rose to the second platform. He placed his hand on the screen.

Their return to the past launched.

Earlier

"Hello Ulrich. How's Emily? You've been going out with her for what? Two months?" asked Sissi.

"I think someone needs to get her facts straight," said Harry as the bell rang.

"Come on, Ulrich! Don't forget we've got Ms Hertz' classes to go to one more time!" exclaimed Jeremy as he pulled Ulrich along.

"Well it wasn't all that boring on Lyoko, was it, Ulrich?" asked Odd as he followed.

"For you it wasn't," said Harry. "For me, it was just another attack."
