All Tricks and No Treat pt.2

"Man, what a great party!" Odd said, tapping his foot to the music.
They were at Kadic, enjoying the annual Halloween Bash the school was having.
"They really outdid themselves this year" Jeremy said. He was dressed like Einstein, white hair standing up all over his head. A laser light show and fog surrounded the dance floor and he smiled as he saw Ulrich and Yumi dancing. He felt a hand on his shoulder and turned around. "Yes Aelita?"
"Remember Jeremy" she smiled, "You promised to show me how to dance"
Odd choked on his cake and looked away, shaking. Jeremy blushed slightly.
"Are you allright Odd?" Aelita asked, patting him on the back.
Odd just nodded, unable to look Jeremy in the eyes.
"Hey guys! great costumes!" Milly said. She and Tamiya were dressed like Sherlock Holmes and Watson, complete with a big white mustache for Tamiya.
"Thanks. Yours aren't to bad either" Jeremy said.
"We got them from the costume store yesterday" Milly said.
"Well, have fun. We'll be back later" she said, walking away.
Ulrich and Yumi walked up to the table, glasses in hand. "So Jeremy, when are you and Aelita going to dance?" Yumi asked, smiling.
"Yeah, I didn't teach you all those moves for nothing did I?" Ulrich asked, teasing him.
"Well, uh, I" Jeremy stuttered. All four of them stared at him until he sighed, held up his hands and said "All right, you win. Come on Aelita". He offered her his hand.
She took it and walked with him to the dance floor, Jeremy's face practically glowing. "Do you think he'll make it?" Ulrich asked.
"Naw, but it'll be fun to watch" Odd said, trying hard not too laugh.
Jeremy put his hand on Aelita's side, her hand in his and her other on his shoulder.
"Ready Aelita?" He asked, blushing hard.
She nodded.
The clock struck 21:00.
And people started to glow.

The sounds of the clocks chiming 9 o'clock rang out thru the air.
And people started to glow all other the school hall.
"Jeremy?" Aelita asked, staring in shock at him.
He stood there, mouth hanging open, eyes almost rolled back into his head.
She watched in horror as black lines, like circuitry spread out all along his face and body from his costume, pulsing like living veins. A large black eye formed on his head.
"XANA!"
With a growl Jeremy lunged at her. "No!" she gasped, holding her arms up.
"Back off!" Ulrich slammed into Jeremy, knocking him away.
Screams filled the hall as other people noticed their friends' transformation.
As one the glowing possessed people centered on Ulrich, Odd, Aelita and Yumi.
"As far as tricks go, Xana's outdone himself this time" Yumi said as she and the rest of the gang went back to back. "Rawr!" Sissi roared, swinging her fork at Yumi. She grabbed the handled and kicked Sissi in the gut, flinging her back into the slowly advancing mob.
"Well, at least you got a good treat!" Odd said, fighting off Nick.
"We've got to get out of here!" Ulrich said, hitting another student away.
Aelita punched a girl out of her way and pointed. "The door's unblocked. Let's go!"
They rushed towards the exit, pushing away anyone who tried to stop them.
"Hiss!" two small figures dropped in front of them. Milly and Tamiya snarled at them, blocking their way. Aelita hesitated, unable to bring herself to hurting them.
"Move Aelita!" Yumi said, stepping around her. Milly and Tamiya sprang up, hissing. Yumi grabbed Tamiya mid air, spun and tossed her into Milly, knocked them away. They burst out of the hall and ran as fast as they could, the mass group of people following behind them slowly.
"Quick, to the supplies room!" Ulrich said. They quickly outran the shuffling hoard and headed for the school's maintenance department.
"We should be safe here for a while" he said, locking the door.
They took a few minutes to catch their breath, and then Odd asked the question on everyone's mind: "Ok, how did Xana possess all of them?"
"It was the costumes." Aelita said. "I saw as it took over Jeremy's body."
"But why not us?" Odd asked. "We bought ours from the same store as he did"
"Xana must have inserted himself into the costumes only recently" Yumi said. "That's how you two escaped. And Aelita and I made ours, so we're safe"
"At least they're not fast" Ulrich said. He opened the door a crack and peered out.
"All clear. Let's head for the factory"
They walked out of the supplies room, armed with broom and mop handles for weapons, and made their way outside, ready for anything.
Or were they?
