Spy Guy: Well...funny story people. see this here, wasn't supposed to be a story, but...it kinda became one. This is going to be 7 chapters long, one for each day Zimmers stays with the Fentons. (You know...from Masters' weapon.) You have to read that story first to understand this one. I don't expect this to get many reviews, but, it helps me channel things for Masters' weapon. :D For those who I sent part of this too, there's more on the end that you haven't read. Enjoy people. :D

Disclaimer: I don't own Danny Phantom. He belongs to Butch hartman. :D

Day one: Double Crossing

The building wasn't the largest he had seen, but it was surely something remarkable. He could almost feel the thrum of activity going on below in the Fentonworks lab.

For a moment, the teenage boy let his mind wander, imagining the scientists going about their activities, completely oblivious to his presence.

The boy looked back at the black sedan that had released him, nodding sharply to the driver. The man gave him a steely look before driving down the road.

He would never be far away.

Zimmers sighed.

It was now or never.

His long fingers reached up to the doorbell, hovering there for a moment. Nervously, the teen bit his lip, drawing red blood. A part of him didn't want to do this. A part of him wanted to run down the street. He wanted to run until he found his mother and father, and tell them everything that had happened. He wanted to let them know he was alive and that he still thought about them every day.

But he didn't. The pull of his Master was too strong. Master's commands could not be ignored… no matter what.

The doorbell sounded with a ping.

The sound startled him for a moment. How long had it been since he had heard one? Hazy memories ran through his mind, showing him running up to a house, ringing the bell, waiting patiently for someone to emerge. He had that feeling again, but this time he was on a mission.

Master was counting on him.

Finally the door opened, and Zimmers put on his best fake smile. His hands subconsciously straightened his blue sweater vest before he bowed slightly. Master had taught him to bow. The gesture seemed to take a worn looking Maddie Fenton by surprise, but she nodded anyway, a smile cracking across her face.

"Babysitter?" Maddie murmured.

"Douglas Randal at your service ma'am." Zimmers smiled.

"Come in Douglas." The woman smiled, gesturing towards a plush couch. Zimmers hesitated only for a moment before he entered the room and sat down on the soft seat. It felt wonderful against his raw back. Much more soothing than his cot. He could have sat there forever…

But Master had sent him.

"I'm sorry this is at such short notice." Maddie continued, shutting the door. "My husband's in Kentucky with his family already. I have to be there for him. It's important. But I don't want the kids to see a funeral so early."

"Kids?" Zimmers asked suddenly. "As in…more than one?

"Yes." The woman replied, dragging a suitcase into the living room. "Didn't your dad tell you?"

Zimmers shuddered slightly at the thought of Vlad being his father. Of course Vlad had called the Fenton's himself. He had to make sure everything went his way. Zimmers shook his head, going along with the ruse.

"He must have forgotten. But I am well prepared ma'am." The boy gestured to the pristine backpack slung over one of his shoulders. "I can handle them."

"You did come recommended." Maddie smiled warmly. "I was leery about you, because you were a boy, but…if Jack says its ok."

Zimmers instantly picked up on what she meant.

"I can assure you ma'am that I would never do anything of the sort." He smiled warmly.

"It's not like I have much of a choice." Maddie sighed. "But you seem very nice. Would you like to meet them?"

"Yes ma'am." Zimmers replied with a smile. This was the moment he had been waiting for. For the first time he would look upon the face of the poor soul who would take his place as Master's personal slave. Maddie disappeared for a moment, leaving Zimmers alone in the room. He took the time to look around the small space, noticing with great interest, the multitude of papers left carelessly around. He would have plenty of reading material over the week. His attention was diverted from his mission by a little girl who was cautiously peeking around the corner. This must be the child Master had neglected to tell him about. She stared out at him with large teal eyes, watching him like a rabbit watches a predator. She was afraid of him.

Maddie walked up behind her, holding a bundle in her arms. She spoke softly to the girl and smiled her warm flawless smile.

Now he could understand why Master loved her.

She was beautiful.

"This is Douglas, Jazz." The woman murmured to her daughter. "He's going to be taking care of you for a while."

The girl nodded, slowly walking forward and staring up at the boy.

"Hello." Zimmers grinned, nodding.

Jazz just stared at him, clutching her mother's suit.

Maddie giggled slightly, gently pulling away, and sitting by the boy's side, the bundle still held tight in her arms.

"This is Danny." She smiled, pulling back the thick blanket. Zimmers' golden eyes were riveted to the child's pale face. Danny's mother gently brushed away her son's dark hair. Blue eyes stared back at Zimmers…carefree…innocent.

A lump formed in the pit of the boy's stomach as he stared down at the half-sleeping child.

Daniel Fenton…

The Masters' weapon.

"Do you want to hold him?" Maddie asked. Zimmers gulped. To the woman, it was an innocent question. She was letting a babysitter hold her son. But in Zimmers' mind it was so much more.

She was his sworn enemy, one of the owners of Fentonworks. He was the head scientist of Axion. He was Vlad's little prodigy.

As he took Daniel in his arms, a huge weight fell upon him. This woman trusted him. He was going to do terrible things. He was going to tear her family apart at the seams.

Danny yawned softly.

Everything would come later. For now, Zimmers was holding a small child, feeling the warmth of a living soul against his chest. A genuine smile poured over his lips as his fingers softly brushed the hair away from the infant's eyes. They were as blue as ice, twin shining gems that softened the teen's heart. For a moment, Zimmers' mind fogged over, all thoughts of his mission pushed from his head.

Had he been like this when he was little?

Had his parents ever held him and felt this feeling come over them?

He hoped they had. This felt wonderful.

"Oh gosh. I have to be going." Maddie said suddenly.

"So soon?" Zimmers asked, looking up, Danny still held in his arms.

"My plane leaves in twenty minutes." The woman continued. "And you know how long it takes to get through security."

"Oh yes." Zimmers replied, nodding. In truth he had no idea. He had never ridden a plane before. It was always that horrid black car.

For the next few minutes, Maddie rambled on about where things were, how things should be done, and what to do in case of an emergency. Zimmers tried to pay attention, but he knew how to take care of children. Vlad had given him books on the subject to read and memorize. It had given him a week long reprieve from the labs, and a welcome one at that. His mission was to do his job in complete secrecy, and then leave without raising any suspicion. To accomplish that, he had to take care of the child…or children as it turned out to be. The experiments would span the entire week.

Hopefully Danny would be fine.

"I should get going if I want to make it on time." Maddie said, looking nervously at her watch. Her violet eyes stared sadly at Jazz for a moment as she took the small suitcase in her hands.

"Alright…sweetie. I'll be back in a week with daddy, alright?" Maddie cooed. Jazz nodded solemnly, putting her small thumb in her mouth.

Zimmers almost cringed as he felt those eyes fall upon him, so trusting…

It hurt.

"Please take care of my children." Maddie murmured. "There's a list of everything you need to know on the refrigerator. Call me if there's an emergency."

"Calm down, Mrs. Fenton." Zimmers smiled weakly. "I know what I'm doing. I won't let anyone harm either of them. You can sleep soundly."

"Alright…" The woman sighed. "Then I guess I'm off."

Zimmers closed his eyes as she left, not wanting to be left alone with the child destined to be a weapon.

Once she was gone…everything would start.

Zimmers discovered an empty spare room on the second floor, quickly claiming it as his own.

Over the next hours, he dragged some Danny's stuff from the room in the basement to the place he would be staying for the next week. The sleeping child was nestled soundly in his crib, surrounded by soft fuzzy blankets, clutching a plushie tiger tight to his body.

After Zimmers had the child situated, he began taking an array of electronic equipment from his bag, setting it up on a nearby table. Carefully, he placed a case of filled syringes beside the rest. With a gulp, he lifted the plastic lid, taking one of the cylinders in his grasp, and squirting out a little of the vile green liquid. It ran down his finger, leaving an oozing trail on his skin.

That would be for later.

According to Maddie's list, it was nearly time for Danny's lunch, and Master had ordered that the child be fed heartily to promote his growth. "Weapons cannot be weak and fragile", he had said, adding an insult to the end.

"We wouldn't want him to be as pathetic as you Zimmers."

The boy took one last look at Danny's sleeping form, before he descended the steps, and entered the Fenton's kitchen.

Holding Maddie's list in one hand, and grabbing a container of formula in the other, Zimmers set out on making a bottle for the boy. It was child's play compared to what he normally had to do in the labs. After popping the rubber nipple on top of the bottle, he tested the liquid's warmth on his hand, finding it cool enough.

When Zimmers approached his new room, he paused for a moment, listening to a soft voice coming from inside, accompanied by a light, airy laughter that reminded him of how Vlad always described Maddie's laugh.

"Like bells ringing in the breeze."

The boy walked closer, peering in the doorframe. Standing before Danny's crib was the little girl with red hair; Jazz.

"What are you doing?" Zimmers demanded, storming angrily into the room. His eyes glanced at his equipment on the table, finding it, thankfully, undisturbed.

"Talking to Danny." The girl whimpered. "He likes it when I talk to him."

"How can a baby even know what you're saying?" The boy snapped, making his way over to the crib, and whisking Danny into his arms. "It's foolish."

The child's hands moved around in jerking motions, before his underdeveloped fingers wrapped weakly around the bottle. Zimmers sighed, putting the tip to Danny's lips, allowing the baby to feed.

"Mommy said that even babies can understand people." The girl pressed on. "She talks to Danny all the time."

"I think it's stupid."

Jazz seemed to wilt as he spoke, her eyes welling up with tears. Zimmers glanced at her, his gaze showing some amount of surprise.

"Are you going to cry?" He asked callously, making sure to hold Danny properly at the same time.

"No." The girl snapped angrily, running a hand across her face. "Mommy lets me talk to him. You're being mean."

"Why don't you go play with your toys or something?" The boy replied coldly, turning away. "I have to take care of your brother."

Zimmers listened as the girls stocking feet slid across the floor as she retreated to her room down the hall. The boy returned to his task, gently taking the bottle from Danny's mouth as he finished.

"There you go." Zimmers whispered, almost inaudibly as gently placed the child over his shoulder.

After the boy was burped, Zimmers set him back down in the crib, his golden eyes flicking over to the table of equipment. He could see the box of syringes, glowing even in the light of day, reminding him of what was to come.

It was then that a quiet ringing brought him out of his thoughts, and the teen reached for his pocket, bringing out a sleek black box.

"Yes…boss?" He murmured, tripping over that last word. Vlad had told him to refer to him as boss on the field. It was strange…but not unwelcome.

"Are you settled in Zimmers?" The cold voice echoed from over the line. "Did Maddie question anything?"

"No boss." The boy replied. "But the Fenton's have two children. A boy and a girl."

"Yes…and your point Zimmers?"

The boy shifted slightly, feeling his cheek grow hot against the device's side.

"I'm not prepared for two. She can't see what I'm doing. She can talk, and she'll tell them."

"Then be quiet. Make her like you."

"But, boss—"

"It's not hard to make someone like you. Maddie obviously liked you if she trusted that phone call from 'Jack'. If she hadn't liked you, then you would have failed, and you'd be punished. It's not hard to make people like you. Be nice to her. Make her think that she's safe. Don't let her know that you're preparing her brother to be a weapon. You're smart, Zimmers. Figure it out."

"Yes boss…" The boy replied softly. "I can do it."

"Is everything set up?" Vlad asked sharply.

"Yes, boss." The boy said, turning to the table. "I'll start tonight, after I feed him."

"Very well then…Douglas." The man replied snidely. "Play a game with the girl tonight, or something. See how smart she is. We might even take both of them that night…after all, you'll need a replacement if something goes wrong."

Zimmers growled underneath his breath as his master hung up on him.

"Bastard." He hissed, pocketing the device, and turning back to Danny. He was sleeping peacefully, still clutching the tiger in his hands.

Zimmers passed the hours reading the various bits and pieces of paperwork that Maddie left lying around. She probably thought that no babysitter would be able to understand the mass of charts and numbers, but Zimmer had spent his whole life doing this. He was a pro.

Eventually, the boy checked his watch, sighing when he saw the day growing weak. It was time.

Dutifully, Zimmers left the room once more, venturing into the kitchen and readying the supplies to make Danny's dinner. As he worked, he became aware of eyes watching him, pricking the back of his neck like twin flames. Zimmers turned, finding himself face to face with Jazz.

"I didn't have lunch." She whispered, looking at her toes. "I'm hungry."

The boy mentally slapped himself. He couldn't let the other Fenton starve. He had to take care of her too.

"What would you like?" The boy asked, trying not to let himself panic. He could make bottles, but any other food was nearly impossible. His master had told him to simply scrounge around the kitchen to feed himself.

But this girl had to have proper food. It was what she was used to. If she didn't get it, she would tell Maddie, and suspicions would rise. Maddie might find out what had been done to her son…and then Zimmers might be captured.

The boy shuddered at the thought, waiting for the girl's reply.

"I want peanut butter and jelly." Jazz announced, looking suddenly braver.

"Really?" Zimmers asked, surprise hinted in his voice. He could remember that. It was simple to make. He used to make it all the time when he was at home…with his mother...

"Momma? Is this right?"

Her face was blurry, erased by time and pain, but Zimmers could still smell the strange tang of green tea that hung around her body. He missed that scent. He missed her.

"That's right Nathan. Good job. You might be a chef when you grow up."

He had wanted to be a chef. His mother was a chef. He didn't want to be a scientist, even if he was good at it. Back then he wanted to be like his mother.

Then Vlad had come and he learned he didn't have a choice. He had intelligence beyond many others; even Vlad himself. But he couldn't do anything with it. He had to listen to his Master. Always to his Master…

Zimmers dragged himself from his memories, and walked over to the fridge, his hand grasping the cold metal handle. It opened with a sick sucking sound, and a whoosh of freezing air blew into his face. The boy spotted a jar of jelly in the door, and took it out. Next was searching for the peanut butter in the cupboards. He went through each one, heavily aware that Jazz was watching him. As his fingers hovered over the handle of one cupboard, the girl cried out.

"Don't open that one!"

Zimmers turned, slightly annoyed.

"Why?" He snapped. "What's in there?"

Jazz simply shrugged her shoulders, and said.

"'dunno."

"A lot of help you are." The boy grumbled, moving to the next cabinet. The peanut butter was near the front, almost empty. Zimmers sighed as he took it in his hands. This would be the last sandwich for the week.

He worked in silence, taking the two pieces of bread, and smearing the toppings on them, before smushing them together, and placing it on a plate. He held it out to the girl, motioning for her to take it.

Jazz simply stood in once place, sucking loudly on her thumb.

"Here." Zimmers snapped. "I thought you were hungry."

"Mom always cuts it into four pieces." The girl replied matter-o-factly.

"But I'm not your mother." The boy growled. "Take it or leave it. I have to feed your brother."

"But momma—"

"I don't care." Zimmers huffed, slamming the plate back down on the counter. "I have to finish taking care of your brother. If you want to eat, you'll take it as it is. Beggars can't be choosers."

That's what Vlad always used to say. Some of the food at Axion was utterly repulsive; experimental stuff claimed to make people smarter. Zimmers figured he was smart enough to know the stuff was useless, but Vlad saw if differently…and his word was law.

"It's always about him…" Jazz whimpered, tears gathering in her eyes. "No one cares about me…"

An alarm went off inside Zimmers' body. This wasn't working. He wasn't obeying his master's orders. He was supposed to make the girl like him…it wasn't working. He had to…had to try harder.

"I'm sorry." The boy whispered, taking the butter knife he had used in his hand. He quickly cut the sandwich into four parts, and held it out to the girl once more, this time trying to rein in his impatience.

Jazz sniffed, wiping her nose on her sleeve before taking the food. She didn't even say thank-you before she was off. Zimmers sighed, turning back to Danny's formula. It was too cold now…he'd have to start over.

Zimmers waited patiently for the boy to fall asleep. He wanted Danny to be out cold when he began. Master had allowed it. The drug would not harm the boy, and it would allow Zimmers to work in silence. The last thing he needed was for Jazz to come in and see what he was doing. He couldn't even begin to imagine the tortures that he would have to endure. It was horrible.

Zimmers watched as Danny's breathing calmed, and his eyes flickered shut, showing that the drug had won its battle. The teen got to his feet, heading over to the equipment table. Zimmers slipped a pair of latex gloves on over his hands, adjusting them with a snap. Then he opened the small white box of syringes, selecting the dimmest of the glowing cylinder's. This one was heavily diluted. It would not harm Danny…yet it would introduce ectoplasm to his bloodstream, not enough to cause any problems, but still enough to prime him for the road ahead.

With a forlorn sigh, Zimmers turned back to the boy's sleeping form…ready to begin…
