Doppler Rex

Chapter 1 - Sleeping Desire

Chapter Rating: K+

I can't wait till this is over. A dodge here, a bob there- "Oof!" One of the evo's handless arms batted him in the stomach sending him crashing into a building. Bricks crumbled and glass shattered - events far too common in Rex's life. He was tired of it. As Termin and Nator connected with the evo's large jelly dessert looking head, he wondered when it would all change for him. Okay big guy, your heydays are over. Rex put away his mechanical fists and laid both hands on the creature's slimy skin. "Uck! Trust me, life is better when you aren't a giant walking see-through dessert." As the evo devolved into a young man sporting a red mohawk, Rex felt a tingling sensation travel up his arms and through his body. It was unsettling, but the feeling soon faded. He didn't think much of it.

"Good work kid."

It was Six with the usual unfeeling tone. He was standing behind Rex sheathing his two jagged blades.

"Can we go now?" Rex moaned. It had been six hours since he ate breakfast. Meanwhile, Bobo is probably stuffing his face with my slices of pizza. "I'm starving." He didn't care if he sounded like a whiney ten year old.

One of Six's eyebrows went up and then went down. "Maybe you should have ended the battle sooner."

"Do you have any idea what it's like fighting an evo with ten arms?"

Six turned around and started walking to the chopper. "No."

Rex sighed. I fight the big one while everyone else takes care of collateral. Why can't I ever just do collateral? I'd like to see some other guy take on my job for a change. These were the same thoughts that crossed his mind many times before, and as usual, he had to remind himself that there was only one person on the planet capable of kicking evo ass this well. He was one of a kind.

. . . .

Rex stormed his way through the Providence base nearly knocking over a soldier. "Sorryhungryherocomingthrough!"

Dr. Holiday raised a hand at the incoming missile. "Hold it Rex! You've got to go through the nanite scanner-"

"No time for procedure doc!" He zoomed by flashing her a bright smile.

"But! Ohhh forget it." She saw Six step through the doors, and she greeted him with a smirk. "A couple hundred lives saved, buildings and roads in need of repair, a big bad brought down by a hyperactive teenager?"

"The usual."

"Don't tell me Rex is getting too much for you to handle," she teasingly said.

Six didn't know what she was implying. He assumed it was one of those female attempts at humouring the situation to get him to reveal how he felt about Rex personally. "Do you know anyone else who is qualified for the job?"

"I'd be hard pressed to find the right man." She outstretched an arm for him to follow and they started walking. "The R-Tool is coming along."

"Any problems?"

"A few. But we should be able to fix them before his surprise birthday."

Six's eyebrows frowned. "What?"

"Well I was thinking of waiting until his birthday to give it to him, you know as a sign of him maturing into a young man who can be trusted to handle this. We owe it to him Six."

"Maturing isn't the right word." No matter how Six saw Rex, he was still that small boy he found in the wreckage. At least, it was the thing he kept telling himself. He was Rex's guardian, and whether Rex realized it or not, his teacher. Only one type of relationship could sustain that. "Every advancement we make here needs to be utilized to contain the evo threat out there. We can't afford to sit on our hands."

Dr. Holiday hugged her clipboard and looked down wearily. It appeared she understood. "All this time with him, and you still treat him like a machine." She only looked at him for a moment. Her eyes weren't angry, just disappointed.

Six remained standing as he watched her walk away. It was clear Dr. Holiday didn't understand his relationship with Rex as well as he realized, even after everything he'd done for the boy. There was no need to say anything. He knew where he stood with Rex, and he was positive Rex was aware as well.

. . . .

Rex was lying flat on his back with his arms sprawled on either side of his pillow. He hadn't even bothered changing his clothes he was so tired. Minutes after flopping down on his bed, he had already fallen into the abyss of sleep.

Starting from the tips of his fingers, hundreds of tiny white sparkles projected from his skin in a continuous flow that traveled down his arms and to his head and body. The last of the sparkles came to his toes and they disappeared leaving his body in a bluish white glow. The transparent light sat up, in the shape of Rex. His head went side to side scanning the room. He swung his legs over the side of the bed and met the ground. As he stood up, the Rex looking shape began to turn solid. His legs turned into Rex's fitted black pants. His white and blue t-shirt took form next. Finally, his skin slowly gained a beige hue, and the hair turned into a sleek black.

The Rex double stood over the real one who was sleeping soundly. He glared at him for a moment, and then walked to the bedroom door.

Bobo was strolling through the hall holding a sandwich in his foot when he noticed Rex. "What's with the midnight stroll?"

"Don't need sleep."

Bobo stared curiously as Rex walked by. The kid didn't even look at him. "Don't bother with the sandwiches, I think they're more than a few days old." Bobo continued on his way as he took a large chomp out of his sandwich.

The Rex double stopped before a door. He looked at a small metal plate on the wall that read "Quarters, Agent Six". Raising an arm, he knocked three times. After a moment, soft footsteps sounded from the room.

"What is it?" Six sounded somewhat annoyed but not obviously so.

"It's me."

The metal doors slid apart and Six stood before him wearing his shades, a white t-shirt and his green dress pants. Six seemed to be scanning him from behind his glasses. "Can I do something for you?" He enjoyed sounding sarcastic without actually sounding sarcastic.

The Rex double scratched the back of his head with a gentle smile on his face. "Can we talk? It's important."

Six stared at him. "I'm busy."

The Rex double squinted. "Doing what? It's one in the morning."

A slight pause. "Meditating."

"Can I watch?"

Six's face went through all sorts of subtle changes. "No."

"Comon, what I have to tell you is a matter of life and death."

"I doubt it."

The Rex double smirked. "I didn't know you meditated."

"Good night Rex."

"Wait! Teach me to meditate. It might help me get some sleep." Rex stared at him wide eyed.

Six had never seen Rex look so interested in him before. He didn't know if Rex was just bored and needed someone to torment, or if he was actually looking to spend time with him. "It's ... a samurai thing."

"Are you kidding? I live to be a samurai. I only wish I could do those crazy air flips as good as you."

Six's eyebrows frowned. He stepped backwards as a sign to let Rex enter. "Don't. Touch. Anything."

The Rex double's smile widened. He recalled the real Rex sneaking into Six's room before to steal one of his green suits.

Six sat down and crossed his legs in front of a lit white candle. He glared at Rex until the boy finally did the same.

"Man it's boiling in here. How can you stand it?" Rex pulled his t-shirt over his head, and then hung it over his shoulder.

Six didn't respond. He was facing the candle, the bottom off his wrists rested on his knees. "Close your eyes and concentrate on your breathing."

The Rex double complied. After ten seconds he opened an eye to see Six was still facing the candle. The double assumed his eyes were closed too. He shut his eye and quietly shuffled his bottom so he inched a little closer to Six. He opened one eye again. Six hadn't noticed anything. He shut his eye and shuffled over moving a bit farther this time.

"What are you doing?"

The Rex double jumped in shock and opened his eyes to see Six's black shades glaring at him. The double chuckled loudly as he rubbed the back of his head. His laughter faded as he faced Six's unchanged expression. The double lifted his chin and looked to the top corner of the room. "Nothin."

They spent seven minutes sitting side by side in front of the flame. The Rex double didn't feel comfortable making another move, so he sat very still with his eyes closed. Breathing wasn't exactly the thing on his mind.

The Rex double found himself outside Six's quarters again. "Thanks Six. That was really ... awesome. We should do it again sometime."

"Maybe." Despite the awkward moment, Six felt like he was finally getting some sense into Rex's thick head.

The Rex double returned to his room where the real Rex was snoring loudly with his mouth open. The double sat down on the bed and gazed at him. Things were going to get very good for Rex. He just didn't know it yet.
