Katelyn tossed and turned in her sleep. Cold sweat dripped down her face. Her clothes stuck to her body. She was having a nightmare.

"Ah!" Katelyn screamed and leaped up. Her blankets were tangled up and twisted around Katelyn's body. She carefully untied herself.

"What a terrible dream," said Katelyn, lying down in her bed. But somehow she couldn't get to sleep.

"Hey, does anybody know where Katelyn is?" asked Danny. He, Sam, and Tucker were in school. It was second period and Katelyn hadn't shown up.

"Why are you worried about her? She's such a snob," said Sam. Danny gaped at her.

"No she isn't! Your just - " he started.

Guys, come on! Lets just get to class," said Tucker. Danny was still worried about Katelyn, though.

Danny walked out of math class, heading toward his locker. He swung open his locker door. He grabbed his books and reached out to touch the Fenton Thermos. It wasn't there!

"Where is it!" screamed Danny, throwing the contents of his locker out in an attemption to find his Thermos.

"What happened?" asked Sam, walking up to Danny.

"I can't find the Fenton Thermos!" screamed Danny.

"Oh, no!" cried Sam.

"Fenton! Manson! Get to class!" yelled Mr. Lancer, who was patrolling the halls. Sam and Danny had no choice but to do what he said. As Danny closed his locker, he was unaware that a pair of icy blue eyes were watching him.

After school, Danny began walking home. Halfway there, a trail of blue mist came out of his mouth.

"Uh, oh," he said. He ran into an ally and transformed. A massive ghost popped out behind a trash can. Danny recognized it as one of Vlad's minions.

The ghost lunged at Danny. He dodged it and shot an energy blast at it. The ghost shot something at him, but Danny went intangible.

Uh, oh. I'm nothing without my thermos! Danny thought.

"Yes, that you are," said a voice. Danny whipped around to see Vlad. He looked sick.

He's probably recovering from the last time me and Katelyn battled him. Danny thought with a smirk.

"What do you want?" Danny asked Vlad.

"Don't be stupid, boy. At least try to be smart," said Vlad. Danny glared at him.

"Don't play with me!" yelled Danny.

"Or what? Are you going to suck me into your ridiculous thermos?" asked Vlad with a smile. Danny stopped dead.

"Oh, that's right! You lost your thermos! Such a pity," smirked Vlad.

"Sh - shut up!" cried Danny. He knew it would do no good. He needed his thermos.

"See here! Little kids do not need to speak dirty when in the presence of their masters!" yelled Vlad.

"What!" asked Danny. What the heck was he doing?

"Apprentice! Finish him off!" yelled Vlad. A figure appeared behind Vlad. She had long dark hair and icy blue eyes. It was Katelyn!

"Katelyn!" cried Danny in surprise.

Katelyn was in her ghost mode. But it was a bit different. She was now wearing all black. There was a red "X" across her chest. Her hair now hung loosely, half covering her face.

"I'm sorry, Danny," she said. She held up her arms. Red smoke shot out from her hands, covering Danny.

"What the - ?" screamed Danny. The smoke suffocated him. He dropped to the ground and fainted.. His mind was now controlled by Vlad.

Vlad and Katelyn disappeared. They reappeared again in Vlad's castle.

"Apprentice, why did you talk to your victim?" asked Vlad, sitting on a stone chair. Katelyn glared at him.

"Because, master, my victim happened to be my friend! And... and..." started Katelyn.

And maybe more. Katelyn thought.

"Whatever you say, apprentice - "

"Stop calling me that!" screamed Katelyn.

"My ghosts couldn't control you. You were too powerful. You could not be used to fulfill my evil deeds. So I blackmailed you with the thought of killing your boyfriend, the ghost boy," started Vlad.

"He's not my boyfriend," said Katelyn silently.

"Whatever you say, apprentice," said Vlad, standing up. "We need to prepare for tonight's battle. Get ready," Vlad disappeared into another room.

Katelyn dropped to her knees and wept. She wept until she couldn't weep anymore.
