Everything was normal in Kadic: Jeremie, Odd, Aelita and Ulrich were together in Maths while Yumi and William were in History. Since planting the virus into the centre of the Cortex and shutting down the supercomputer they have been able to live easier and concentrate on their studies.

Later, during lunch Yumi and William weren't able to join the others due to a group project they had to work on and complete before their deadline. So the quartet hung out together in the rec room without them.

Soon their final class, IT, approached. Jeremie and the others were working in the computer room on a class assignment when something surprising happened. Another classmate fell back, his chair knocked over from seemingly an electric shock. The teacher quickly arrived at the scene and told the rest of the students to return to their work as he would resolve the problem. Aelita who was sitting next to Jeremie quickly faced him.

"Do you think it was XANA? she inquired grabbing his hand with a look of pure curiosity on her face.

"Why would it be?" he whispered back "Isn't it frozen? As long as no one pulled the switch in the factory I'm sure it's return is inevitable... no one would enter the abandoned factory... no one has and no one will...besides the kid had a water bottle next to him... I'm sure he must've accidentally spilled it or something..."

Aelita slowly released her grip allowing Jeremie to return to work. She gave a sigh of defeat then looked back at the boy who was now being helped back on his chair wondering if XANA was really awake again. She shook her head and turned round to face her computer again but as she did she saw that the student's water bottle was sealed and not spilled at all like Jeremie thought it was.

After classes the gang regrouped and headed to the rec room. The gang didn't do much. William and Yumi were doing their mountain load of revision and classwork., Odd was on his phone, Jeremie and Aelita were talking to each other and Ulrich was sitting near Yumi watching her and William do their revision.

"Well guys... I'm going back to my room..." Aelita yawned standing up and stretching.

"Yeah me to..." Jeremie added leaving after her "I got my laptop in mt room; I got work to do..."

Slowly, one by one more students started to leave including Yumi who said she had to go home. Ulrich bored out of his mind decided to leave as well and followed behind her before parting ways. Soon there wee only three students left: William, Sissi and Laura. Sissi was usually the last to leave as she had the keys; other times she gave them to someone she trusted who returned it to her later.

After another hour William finally got up; Laura soon followed. Sissi gave a sigh of relief and trailed after the two then locked the door.

...

The next day in gym class Jim was teaching them different tactics in sport. He was droning on and on; only half the class was listening. Odd sighed loudly running a hand through his hair.

"What's wrong? Jeremie asked "Don't find this lesson interesting enough?"

"Sometimes I wish XANA was back" he sighed expressively "...then life would be waaay more... exciting..."

Jeremie raised an eyebrow. "Don't forget, Odd, that we have ti juggle both school work and Lyoko" he informed sounding annoyed "...and I had enough of XANA ruining our lives"

"Yeeeaah I know... but still" he sighed placing his arms behind his neck "It's boooring"

"Belpois! Della-Robbia!" yelled Jim catching their attention " You two seem to be having an interesting conversation... is this conversation more important than my lesson?"

"Oh no sir!" said Odd waving his arms " Carry on, we apologise" he bowed; half the class laughed.

Jim gave off a not-impressed face before continuing.

"Soo..." he sighed "Where was I... ahhh yes..."

Odd got up from his little bow and grinned. He looked back at their gym teacher before everything suddenly went blank. Jeremie carried on listening, only half caring. For a second he casually cast his sight on Odd. He was strangely standing there wide eyed.

"Errmm... Odd... are you okay?..." he asked noticing something was off.

Odd turned his head to look at him with a glare in his eyes then suddenly punched him before he had the chance to say anything else.

"Odd! What is wrong with you!?" Jim yelled again.

He and the rest of the class saw him sprawled on the ground and Odd with his fist out in front of him. Odd ignored him and glanced over at the ex-Lyoko warriors as Jeremie scrambled to get up. He then clumsily put his glasses in position.

As Jim was berating Odd who was still glaring their way, Jeremie signaled Ulrich and Aelita as he came over to them.

"Ermmm... Jim... Ulrich feels kind of sick...can Aelita and I escort him to the Infirmary... he might not be able to do his best in class..."

At first he was confused but got the message and held his stomach in grimace while groaning in pain. Jim looked at him unsure weather to believe them or not but decided to let them go. The three took this chance to escape. Odd having budged through all the kids to get to them continued to follow their trail with a preserving emotionless face.

"Hey Odd! I didn't allow you to go!"

His yells went unheard as said person continued onwards.

...

What's wrong with him?" Ulrich questioned confused as the trio were now running once they deduced they were out of Jim's sight.

Jeremie, who was behind the two, then told them to head to the forest. Both looked at each other bewildered.

"It must be XANA..." he finally spoke out as they made it to the entrance of the forest.

"W-What are you talking about? What do you mean XANA?!" Ulrich snapped at him suddenly, his fists clenched.

Jeremie having caught his breath got up and walked past the two through the forest. The two knew where he was heading but Ulrich wished it was a joke.

"Just calm down" he assured "I'll tell you after, we just have to get to the factory..."

"Why?"

"You know why..."

Ulrich knew of course... but still wanted to believe this was all a trick... a joke... it couldn't really be back now... could it?

"Okay... say... say... this is true- never mind actually... how do I know this isn't a trick?"

Once they made it the area where the entrance to the sewers was Jeremie looked at him like he was crazy.

"Ulrich... stop trying to deny this, I hate this as much as you do but... we can't deny the truth..."

Just then they heard someone running towards them. Ulrich stood in front of the two in a fighting stance while Jeremie opened the manhole.

Thankfully, it turned out to be only Yumi who seemingly managed to outrun Odd.

"I thought you might be here... What's going on Jeremie?" she glared at him with her arms folded.

"What do you think it is?" he muttered already putting his legs down into the hole to start his journey to the factory.

"No way..." she blinked unfolding her arms "You can't be serious..."

"I'm afraid I am... what other answer would there be?" he stated bluntly "By the way... where's William?"

His question was soon answered when Odd caught up to them with said person right behind.

Okay... so him too..." he muttered "We better get down then..."

One by one they all quickly went down into the sewers and ran through it to reach the factory as they still did not have their transport methods from back then. Mentally, Jeremie made a note to get them back or at least get some new ones. He really didn't like running to the factory.

Soon they all clambered out of the sewers, Jeremie unfortunately last, and ran over the bridge towards the factory. Only then did Aelita speak.

"How're we going to turn them back to normal?" she asked out of the blue.

"Well... we'll have to think of something..." Jeremie replied unable to provide her with an answer.

"We're going to turn on the supercomputer on again right?..." Ulrich asked "Why else would we be heading here..."

"Well... yes obviously... I'm not sure why... but... since XANA is seemingly not attached anymore... we might as well try..." Jeremie suggested.

"Will that really free Odd and William?" Yumi questioned as they headed to the lift.

"Well... it's probably best we check if it is on... if it is... we might need to check for any activated towers" Jeremie stated.

"Wait! You guys go... I'll do my best to head them off or even stall them as long as possible..." Ulrich said walking out of the lift.

"I'm going with you!" Yumi ran out of the lift and stood alongside him "Two is better than one right?"

He blushed slightly with a nervous 'yeah..." Jeremie rolled his eyes then pressed the button.

"You guys better be safe" Aelita said with a glare.

"Don't worry princess, we got this" he gave her a thumbs up smiling as the doors fully closed them off.

"Ready, Yumi"

"Sure... always ready..."

Both faced the entrance of the factory to see the two leap down from the ledge. At this instant Ulrich runs right at Odd to try and knock him out. but ends up going right through him.

"Are they possessed by spectres or something?" Yumi muttered raising her eyebrows as she faced against William.

"They can't be... unless not being on Lyoko for too long can make you vulnerable to-"

He didn't finish his sentence as Odd threw a punch at him. Yumi watched horrified as he was thrown against a beam, hard.

"Ulri-"

She didn't finish her sentence as she barely dodged a kick by William.

"What are you trying to achieve by turning on the supercomputer on XANA?!"

He didn't reply; just gave evil grin.

"So no reply huh?" she muttered.

She backflipped away from him then ran towards Ulrich by knocking out Odd from behind. She helped him up.

"Thanks Yumi..." he groaned as she put his arms round him.

"Don't thank me yet..." she said as William changed direction towards the lift.

"You're not part of the supercomputer... aren't you? So why are you turning it back on?" Ulrich yelled.

Odd didn't say anything as a surge of electricity surged from his hands

"Damn..." she growled.

...

The other two having reached the final floor approached the large and empty space. The console where the switch was located was within the floor but rose before them as the lights turned on with their presence.

"We should turn it on quickly... I don't know how long they will be able to stall for us..."

Jeremie's hand shook slightly as he reached for the handle.

"I... the thing is... I'm not sure...what would happen once we do..."

Jeremie... nothing will change between us... I promise..."

Before he could say anything else the doors of the lift opened revealing William and Odd.

"Jeremie! Quick!"

"I err..."

With nothing to say he quickly grabbed the handle and turned it on. In that instant both Odd William collapse.

"We did it, Jeremie!" she grabbed his hand happily.

"Yeah... we did... we should check on them though..."

"Yeah... sure"

Both headed to the unconscious boys who were now getting up.

"W-What's going on?" Odd drawled rubbing his head.

"Don't worry, we'll explain later... I'm just glad you're okay..."

"Hey William... you okay?"

"I... I think... I am...?" he groaned gripping the side of his head "What happened?"

"Well, I'll tell you later..." he smiled holding his hand out for him as Aelita slung Odd's arm round her to help him up "...but now... we got to turn this off"

He looked over at Aelita, who nodded, then went up to the console. William walked up next to him.

"Are you sure... about this?"

Yes. I'm not sure why... but if XANA is desperate to get the supercomputer running it could have attached itself to it... so... I want to check..."

He gripped the handle and pulled it down. Suddenly, just then Odd and William lose consciousness again. Aelita barely able to hold Odd's unconscious body looked over at Jeremie confused. He was holding William who happened to fall into his arms.

"Jeremie... What's going on?"

"I-I'm not sure..." he started still holding him "... but... I think... I think XANA might be connected to them in some way..."

"You mean... like me... before..."

"I... I don't know..." he replied as she carefully placed Odd on the floor "I'm not sure what XANA's thinking but... we have to turn it on again for their sake..."

Releasing a sigh from his lips he carefully placed William on the floor.

"Lets just hope this wakes them up again..." he muttered pulling the switch.

A minute passed. Aelita walked back and forth while Jeremie sat down next to William gripping his hand.

"They got to... they have to wake up..."

Just then, William groaned and opened his eyes.

"Are we... still here...?"

"Yes! They're awake!"

Odd, still on the floor, also opened his eyes peering over at Aelita standing nearby.

"Been watching me huh?... Princess..." he smiled tiredly.

"Oh shut up" she scoffed glad he was awake nevertheless.

Jeremie looked over at the switch again. William who was sitting on the floor next to him watched him with concern.

"Jeremie..."

"It seems like... it might be true..." he looked over at Aelita.

She nodded "Yeah it is..."

"XANA... is back..." he stated as the lift opened.

Yumi and Ulrich walked out and saw the four wondering what went down but they didn't ask.

"...and the Lyoko Warriors are back in action too huh?" William added as the room was enveloped in silence.

I had always wanted to make a Code Lyoko story but never made one since I never had an idea for what the story and plot would encompass; one night I had a weird dream concerning Code Lyoko which will be the ending for this story (so I just made a whole story from there) so stay tuned.

Also this is a story that takes place after the events of Evolution.

Also, disclaimers: Code Lyoko does not belong to me except for a few characters that will be introduced soon.

For those who don't know: In Evolution Odd's actor did not have his hair up like the animated series. I believe that he may have returned to how his hair was like during the beginning of the show (or they didn't bother doing his hair up but I'm gonna keep with my idea anyway) after they seemingly finished him off at the end of season 4. Then as season 5 came along he kept it that way. So in this story he continues to keep it that way.
