Endless Possibilities

Chapter 1

It was just another day for Raph as he walked out of the dojo. The punching bag swung sluggishly behind him having just taken 10 rounds with his green fists, Leonardo was meditating with Master Splinter in his room and Mikey was plunked down in front of their multiple television tower watching 3 cartoons at once. Everything was perfectly normal with the scene from the smelly incense wafting from Sensei's room to the annoying drone of childish music in the lounge room. Everything was perfectly normal… until his immediately younger brother Donatello came rushing out of his room grinning like a mad man only to promptly collapse on the floor.

Mikey as usual eloquently summed up the situation with a single word, "Whoa…"

Raphael ran over to his brother now sprawled face down across the rug, "DONNY!" Turning the turtle onto his shell he quickly assessed the purple wearer's condition, "Donny…?"

"What the shell… He's just asleep."

At Raphael's assessment Mikey burst out laughing not able to the stand the look of disbelief spread across Raph's face which had begun to turn crimson as anger consumed him.

"Bloody brainiac, gave me a shellin' heart attack. What does he think he's doing?" Raphael stood up letting Don's head thump back onto the floor with little consideration whether it woke the turtle up.

"Awww… Come on Raph look how cute he is when he's asleep? I mean nothing like the brilliant maniac we all know him to be. Besides I'm pretty sure he hasn't slept in like, ummm… four days."

"Four days… really?" Leonardo asked, coming to investigate the commotion he couldn't help but hear from Master Splinter's room.

"Yeah, haven't you guys noticed? Like every night this week, dude's been awake when I've clonked out on the couch."

"Now that you mention it, Don's been awake before me in the morning lately. I just assumed he wanted to start off his day nice and early like me."

"Yeah Leo, everyone wants to be just like you." Raph scoffed, not able to help himself.

After throwing a glare at Raph, a guilty expression came across Leo's face. "I can't believe we didn't notice?"

Raph knew exactly how Leo was feeling. He was the brother who usually wound up either tying Don to the bed or just knocking him unconscious when the small turtle was too engrossed in a project to sleep. For Donny to have gone four days without sleep made Raph feel like the crummiest brother ever to walk the Earth.

It was easy to do though. Donny often got overlooked and sometimes ignored by his family, although never intentionally. Being the other middle child Raphael also got this treatment to some extent, but he made up for it with his explosive personality. Don was always the quiet one though, content with just being in the background until his family needed him. Having to deal with Michelangelo's exuberance, Raphael's unstable emotions and Leonardo's insecurities as children Splinter had unintentionally allowed Donny to take a back seat to his brothers needs.

This had all led to the current events, of Donny lying in the middle of the floor sleeping peacefully.

There was even a small puddle of drool growing beneath his head.

"Well I guess we should get him into his room?"

"You're right Raph, that floor can't be any good for his back. Speaking of bad backs, have I told you guy's how mine's been playing up lately? Guess I shouldn't be lifting anything heavy?" Mikey was already shuffling towards his original place on the couch at the mention of physical labor.

"Sheesh, Mikey thanks for the help?" Sighing Raphael moved towards Donny's feet as Leo moved to grab Don by the shoulders. "You ready?"

It was a testament to exactly how exhausted Donny was that he didn't wake up once the entire trip. Not even when Leo "accidently" knocked his head into the door frame. Walking into the lab/bedroom Raphael noticed straight away that this wasn't any normal obsessive exhaustion on Donnie's part. The purple turtle couldn't be called a neat freak, but he always had a place for everything. No matter how into a project or experiment he was, his lab was always exactly the way he wanted it. There was no way the lab's current state was how Don wanted it.

Sheets full of calculation covered every free space including some of the ceiling. On the whiteboard Donnie had salvaged even more space for calculations writing some straight over the old ones. Raph even saw an equation which started on the blackboard and continued over Don's wall. Most disturbing of all though was the fact that not only had Don left both his computer's on, but the Bunsen burner still happily boiling a beaker of some unknown chemical in the middle of his desk. The only tidy area of the room seemed to be the bed which looked like it hadn't been used in a while other than to hold papers.

Carefully navigating the mess, the two brothers carried the third over to the mostly tidy bed and gently lay the exhausted turtle down.

"What do you think all this stuff is about? I mean what in the shell has Don been doing for the past four days that could be so important?"

Leo looked back at Raph the same concerned expression mirrored on his face. "I wish I knew."
