Night fell, and Jeremy, Nick and Ulrich knew what to do. They ran towards the south side wall of Jim's little cabin-thing. Ulrich took out a blue can of spraypaint and smirked, Nick grabbed red spraypaint.

Meanwhile, Jim was sleeping in his cabin-thing, as normal. In came a certain chihuahua named Kiwi. Kiwi walked around a couple steps and started to bark very loudly. Without doing any good, it hopped up onto Jim's bed and grabbed his blanket. Finally, Kiwi got fed up and bore its sharp teeth. Jim instantly felt the pain after Kiwi issued its attack.

"Stupid mutt!" yelled Jim. Wincing in pain, Jim chased Kiwi out of the building. As Jim was trying to get his hands on the mutt, he spotted Jeremy doing something suspicious in the middle of the quad.

"Jeremy, do you mind telling me what you're doing outside at this hour?" Jim looked at the wall. An image of a Jim shaped like a sad clown being pied gazed before him. He was shocked.

"Sorry Jim, but if you came later the facial details would've been nicer," he smiled.

The principal was talking to Jeremy in his office the next morning. "I hope this will teach you a lesson, Jeremy. I don't understand why a student like you would..."

"Uhh," interrupted Jeremy, "I understand." As he walked out of the office with his five friends, a smile became evident.

"So, how'd it go?" spoke up Odd, the funny friend.

"Ohh," replied Jeremy, "The principal gave me detention for the entire week. I guess I'll have to stay here for the whole week of vacation."

"All right!" exclaimed Ulrich.

Nick ligered away with Ally to the back stairs in the hall, "Ally, umm... listen Jeremy has asked me to uhh... stay behind to help him with gaurding Lyoko so, I can't go with you to that ski resort in Switzerland."

"Uhh... okay. I'll ask my neighbor Lynnette then." Ally replied, taken aback to his sudden change in plans, "I've got to go home and pack, bye."

"Sly as a Foxx," Nick mumbled going to his room.

"Xana sure won't have a vacation with you on campus, huh, Jeremy?" said a dark-haired girl named Yumi. She led the three guys, Summer and Savanna down the hallway. Unfortunately, someone (or someones) was watching.

"I don't get," said Nicolas, "Why did Jeremy look happy when he got detention?"

"It's almost as if he wanted to get it," said Herve.

"You know what?" said Sissi. "I'm going to try to find out just what's going on between them." She walked herself into her father's office.

"Excuse me, daddy, but could I talk to you?" said Sissi.

"Sure, sweetie," answered the busy man. "What is it?"

"Well," said Sissi. "I have this friend...who hasn't been receiving many good grades, but she also promised to visit her sick aunt. However; she wants to try to raise them before the semester ends, but she can't find time to study. What do you think she should do?"

"Well," thought the principal aloud, "I suggest that she stays home over the break so that she could have some time to study more. Who...is this girl, by the way?"

"It's me, daddy!" exploded Sissi. She ran up to her father and gave him a kiss on the cheek. "Thanks a bunch, say hi to aunt Vera for me!" She ran out of the office with a smile.

As she made her way to the hallway, she bumped into a certain blond nerd, and devilishly handsome black-haired boy. They all fell to the ground.

"Sissi," said Nick. "Why are you in such a hurry?"

" I know you're staying at school over the vacation, and you get to spend every second of it with little, ol' me." She pointed to herself slyly.

"I'm staying here too, Celeste needs me to help her..." he looked into Ms. Hertz room were there was alot of textbooks, "unbox the new textbooks."

"Is that so," Sissi spat at him, "well I'm going to be watching you two then."

"Oh no you won't!" spoke up Jim, walking towards Jeremy. "The only thing you'll see is textbook pages flipping. As for you Belpois, that wall isn't going to clean itself, you know. Fox I have word that you help so..." Jim growled, "Alright, you three stay here. I'm going to go grab a few sponges." When he was out of sight, Sissi started up a menacing conversation with Jeremy and Nick. She eyed the graffiti on the small wall.

"So, you two did this all? Doesn't look like you could do all this in one night."

"What's your point, Sissi?" asked Jeremy. "I know you're up to something." Nick nodded in agreement.

"Oh? Then tell me who XANA is." Sissi felt triumphant. Jeremy felt weak.

Jim made his way to the storage room, which was part of the basement under the science lab. It was a huge basement; enough to store all of the equipment that the school and faculty needs, like sponges. Jim took what he needed off of the shelf, and closed the door on his way out. As the room became dark, an even darker figure emerged from an electrical outlet.

"So who is XANA?" questioned Sissi. "I never heard you mention her until just this morning. Is she your girlfriend, Jeremy?" Nick just wanted to hit her so badly right now.

"XANA is..." stumbled Jeremy.

"A new type of grading sytem for genuses like Jeremy," he lied leaning on Jeremy's shoulder.

"Oh yeah? And how am I supposed to know that?"

"Good point cause your grade point average is what, 0?" Nick taunted, Sissi grew red with rage.

"You're the one that asked." Jeremy looked around. "Here comes Jim. Get ready for a whooping."

That night, Jeremy and Nick decided to head over to the factory. It's been too long that Aelita was trapped inside that computer. He just needed to try to get her out one more time, yet he didn't want to put a set timeline on his secret romance with Nick. They sneaked past Sissi's room and tried to get through the secret passage to the factory through the basement. Suddenly, from the under the door a thick, grey steam spilled into the room, yet it didn't make them sweat. It must've been a gas. As they were coughing, a brown-haired man stepped closer to him.

"Alright, Jeremy, Nick. Now what's the deal?" argued Jim.

"Jim!" coughed Jeremy. "Look in there!" He pointed to the basement door. "Something's gone terribly wrong!"

Jim opened the contaminated door and stuck his head inside the basement. "What? I don't see anything."

"But," stuttered Jeremy, "The gas...It's gone..."

"You think-" Nick mumbled.

"It must be XANA." Jeremy whispered back.

"Alright," said Jim. "Back to your rooms."

Jim walked out of the basement very aggravated. Jeremy and Nick decided to go down to the lab instead.

Sissi was sleeping in her room when she was awoken by a loud noise. She looked up to where she thought she heard it and saw a murky, grey smoke coming out of the air vent.

"Oh, no! What's that?" she screamed. She ran all the way down to Jim's bedroom and shook his shoulders violently.

"Jim! There's a creepy grey smoke coming into my room. You have to check it out!"

"What's all this about smoke?" said Jim, sleepy-eyed. Suddenly, the smoke started to enter his room, too. "What the?" He pushed Sissi out of his room and shut the door behind him.

Jeremy woke up the supercomputer once he made his way to the factory and down the elevator. Nick leaned on the chair waiting to see wheteher or not to go to Lyoko.

"You're wrong Aelita," Jeremy said. "XANA has launched an attack."

"Oh?" said Aelita.

"I've centralized the tower to be in the Forest Region so, it'll take me some time to get there." Jeremy informed her, "XANA's pulled out all the stops he's got an army of monsters waiting. I'll send Nick."

"Okay. But I'll need some more help." Jeremy, Nick and Aelita put their heads together in deep thought.

Ulrich's math tutor entered his family room, eager to start teaching him the basics of algebra. Ulrich was deeply wishing that he could have spent his vacation...actually going on vacation.

"You won't believe how excited I am to be here, Ulrich," said the gray-haired woman. At that moment, Ulrich's cell phone had received a text message.

"Sorry, Ms. Schmidt," said Ulrich, "but I'm just gonna go grab my workbooks."

"Take your time," she smiled. When he saw her turn her back, Ulrich ran out the front door.

Summer was at a block party with her friend Leslie Devine. She was enjoying a candy apple while playing with her glow in the dark hula-hoop, which she won.

"I feel so groovy," She said as her cellphone vibrated, "like a hippy."

Odd was at the airport, ready to take his luggage from customs. The security guard asked him to remove his back.

"Why would I want to do that?" asked Odd.

"Well," said the guard, "You see, here at Customs, it's customary that you hand over your bag." He held out his hand.

"What if I don't want to?" asked Odd defensively.

"Okay, then could you at least tell me what's in there?"

"Well you see between you and me, I collect artifacts for my sister," Odd's bag made a barking noise.

The security guard lifted an eyebrow. "Artifacts that talks?" At that moment, Odd cellphone rang, "speaking of that she-devil. Hey Adella."

"Adella?" Jeremy answered.

"Uh-huh. I got it. You'll sue if it's even scratched," he said out loud trying to be intimadating

"Just get here."

"Hmm... maybe my sister would rather have this ancient endorsable item on 'TravelLine' instead," he said out loud as he stormed off looking quite regal.

Yumi was sitting in the car upset.

"So you're telling me that we drove 2 hours to a baby shower that is going to take place tomorrow? Real smooth, Dad,"

"Sorry, Yumi," said her father, Takeo. "See, these are the things you could tell me before we leave." He parked in front of the driveway.

"At least we're back at home," said Yumi's mom. At that moment, Yumi got a text message. She opened the car door quietly.

"Say, Yumi, why don't we all go out for dinner right now, huh?" Takeo and his wife turned around to see that they were the only ones in the car.

Meanwhile, Jim and Sissi were trying to escape from the madhouse-like school. They were about to make a dash for the double doors in front of the school when out of nowhere, a grey gas spilled from the lights.

"Jim!" Sissi screamed. "I'm scared." She huddled up against Jim's large body.

"This is strange," said Jim. "Fog doesn't usually act like this." He stared at the fog, which looked pretty strange to start with. When he looked closer, he saw that a pair of piercing red eyes look back at him. Just then a small blond-haired monster flung itself at him. The beast tore a piece of skin from him and lunged again towards the two, and Jim acted quickly. He shoved himself and Sissi into the janitor's closet close by.

"We'll be safe in here for now."

"Safe? We'll be lucky if we spend an hour here suffocating. It's not like Jeremy or Nick are still on campus," complained Sissi.

Jeremy rushed onto the school grounds and looked around for anything suspicious.

"Sissi? Jim?" he called. "Where are you?" Suddenly, the the monster busted open the front doors of the main building and was about to attack Jeremy.

"Ahh! Wait your just a yellow-thoraxed spider." he breathed. The little spider neared Jeremy and started to spew tons of volumes of grey gas. "Oh no, it's using it's poisonous gas!" He covered his nose and mouth with his blue sleeves and thought to himself. "I know," he coughed. "It's blind and attacks sound." He leaned over and picked up a stick and threw it into the woods surrounding the school.

"Shit, I can't move!" He fell to the ground. Luckily, his three friend Yumi, Summer, and Ulrich came just in time. They carried him towards the exit.

Jeremy blinked his eyes rapidly as they put him down.

"What's wrong?" Summer asked stunned at his never ending blinking she thought he was having a seizure, "Uhh... two, no three words," She stammered at his three blinks. First word," Jeremy strted to cry, "Umm... sad, no, crying, no..."

"Tears, emotional?" Yumi chimed in.

"Uhh... tomato bisque, crocodile urine," Ulrich guessed. Yumi and Summer just stared at him.

"Uhh... uhh... Sissy," Summer said. Jeremy blinked 'yes'.

"Second word." Jeremy looked at were they had gym everyday.

"Gym?" Yumi asked. Jeremy nodded.

"Sissy, gym, sissy, gym. Wait Sissy and Jim are they inside?" Summer asked, Jeremy blinked 'yes' again.

"I'll go get them," said Ulrich. He ran towards the school and ran inside the main building.

When Yumi, Summer, and the slowly unnumbing Jeremy got to the factory, Odd was waiting for them there.

"You're early for once, Odd." said Yumi.

"Alright," Jeremy slurred from his decreasing paralyasis "You guys have to get ready to dive in. Nick and Aelita are probably won- won- wond-er-ing were you are." Yumi, Summer and Odd made their way to the scanners. "Scanner Yumi. Transfer Summer. Virtualization."

The three virtualized into the Forest Region where Aelita and Nick were ducking under a larged overturned log waiting for them. Unluckily, so was an army of Roaches.

"Watch out!" said Odd. He dodged a Roach attack before he reached the ground.

"Stay behind me, us Aelita." motioned Yumi and Summer. Summer shot her stinger. It missed; howerver, the Roach flinched long enough for Yumi to throw her fan and destroy it. Another monster came from behind it and started to fire at the heroes.

"Watch out for the hornet," said Jeremy over the speaker. He made a call to Ulrich. "Ulrich, did you find them yet?"

"Not yet," Ulrich coughed. He limbered through the hallways filled with grey gas.

"Well," advised Jeremy, "you'd better get out of there! You know how deadly that spider's gas can be?"

"I'm going to try one more door," said Ulrich. He chose a locked door and knocked repeatedly on it. "Sissi! Jim!" he called. Soon enough, he ran out of energy and passed out. Sissi heard him through the closet door.

"Was that Ulrich? Oh," she said delightfully, "he came to save me!"

Back on Lyoko, our heroes were trapped behind a tree, taking cover from the Roaches.

"How are we ever going to get past them?" said Aelita with a worried look.

"Summer," said Odd. "I think this is a good time to test out your new power."

"The one that Jeremy discovered?" asked Aelita. Summer nodded. She flew in the air and shouted, "Belladonna!" Her body had a black aura, and a form af black powder escaped from her newly grown stinger's end, the Roaches were in a ditzy loop as the belladonna was doing its job, hallucinating. Summer's life points were drained. The gang kept on moving. Yumi tried to destroy one, but the belladonna wore off and she was hit.

Jim dragged Ulrich inside the closet and noticed the device in his hand.

"A cell phone," he rejoiced. Jeremy answered to phone. "Hello?"

"Is that you, Jim?" answered Jeremy.

"Who is it?" Sissi asked Jim.

"Jeremy," said Jim. "you need to help us. We're running out of oxygen, and..." The spider's gas started to seep in from under the closet door. Jim choked and dropped the cell phone.

"Jim!" said Sissi.

"Jim?" said Jeremy. "Answer me!" Yumi entered the computer lab. "Odd, Nick, Summer you need to hurry up!"

"We are!" hollered Nick. the three and Aelita reached the activated tower, which was surrounded by a pool of digital water.

"Now what?" said Summer. "How are we going to get to the tower? I can't lift Aelita."

"Cats' don't swim well," Odd gulped looking at the water.

"I got it," Nick exclaimed. He grabbed Aelita's arm and spun her around, let go and she was safe on the island with the activated tower, "That solves our problem."

Aelita moved up the tower as Jim, Sissi, and Ulrich lied motionless underneath the spider's gas. The spider in the field chasing a gopher was frozen after Aelita entered the code.

"Return to the past, now!" said the boy with glasses. A bright light emerged from the factory's core.

Back at school, Nick pulled Jeremy over after he finished talking to Ally, "Listen Jeremy, I think we should go to the next level," he said staight to the point sticking his hand in Jeremy's pants.

Sissi was watching from afar with Herve and Nicholas trying to listen to everything she said, "somethings fishy."

"Oh thats me I had a talapia for lunch today," Herve weezed.

"No, not that, about Jeremy and Nick," Sissi whispered loudly, "I think I'll dig around a bit."
