So this is a long one! Some Donnie and Mikey fluff because they make day!

Okay I am going to go on a little rant here because I got something to say! If you don't care just skip it, HERE I GO

I am a little bit upset that 2k12 doesn't expand much on Mikey's and Don's relationship! I mean there's a little bit but In my understanding, Mikey and Donnie were best friends. At least that's how it is portrayed in the 1990's movies, 2k3 series, and 2007 movie. They were besties! Especially in 2k3! They were obviously close and I really enjoyed that Donnie let Mikey joke around and be witty! Because Don would joke around and be witty back, he endulged in Mikey's silliness often. Which was cute because he's more serious of a character (less serious then Leo though)! 2K12 goes more into Mikey's and Raphs relationship, which isn't a bad thing, their bro fluff is adorable too and I love it. I'll embrace the different, but Mikey and Don are still my favorite. Opposites, yet they have a really strong bond. However Mikey is actually supposed to be real smart! Not like Donnie, but in the comics Mikey was really smart, I mean he is a witty character and funny! Humor is often based on intelligence! So...okay I am done now

Anyways, Hope you all like it! C: If you don't I'm sorry, I'm going to try to post a funny one (hopefully funny) Soon for all you people who like my silly chapters.

I can't do this. I can't! I am a failure! Why do I suck? I totally suck.

Donnie thought as he stared down at the equation in front of him. He has been working on this for weeks! It was a vital step to finding and making a retro mutagen, but he hasn't had any success. His confidence was draining and the frustration coursed throughout his entire being! His brain felt fried and roasted but he couldn't stop. He had to keep going, he had to.

Donnie let out a frustrated little yell and slammed his head down on the desk, not caring about the pain. His stupid brain deserved it anyways! Maybe he should try hitting his head over and over again until an answer comes up. His eyes were so heavy, but sleep was not an option. He couldn't sleep even if he wanted to. His brain was just a constant flow of thoughts anyways and it would nag him all night. It was relentlessly working and refusing to give the turtle genius any peace! He turned his head and looked around the lab.

It was a disaster.

Papers were scattered everywhere, some crunched up into a ball of anger and frustration. Empty bottles of mutagen piled in the corner. Equipment was stacked on the counters and ready for use. His computer screen had all the data he could find, but they seemed to be taunting and laughing at him. An army of empty coffee cups were also thrown around the room in random places.

He has been working so hard for so many days. He has barely eaten and barely slept. Yet he has nothing, nothing! No results at all. He was considered a genius! With an IQ ranging around 160, he has built complex machines out of garbage, preformed medical treatments on his brothers with only textbooks and the internet to consult with, he's disabled explosives, fixed the toaster and everything else that his brothers break. He has done things that he would never think he could do! So why can't he get this?

Donnie grabbed the recently used up canister of mutagen, another failed attempt, and stared at it.

I fail!

I can't do this. But everyone is expecting me to. Why can't I figure this out? Why am I so stupid?

Don meant to throw the canister towards the pile of disappointment, but his anger take over and he chucked it harder than intended. It hit the wall and the glass shattered, raining over the heap of failed canisters.

He ignored it and reached for his cup of coffee. He noticed his hand shaking from lack of food and sleep. An excess amount of coffee did not help the trembling. He took a sip but only a single drop touched his lips. He felt his spirits plummet; no coffee is a low blow to an already downed turtle. He glared at his cup with hate. Great. Betrayed by caffeine! He's a failure, an idiot, and now no coffee! His frustration was reaching the breaking point. The mental wall he puts up to keep out the overflow of emotions was crumbling down.

So much pressure.

He has to get this right. He has no choice in the matter. He's never done well under pressure, but he has made due in the past. He had to! There is no failure for Donatello. He couldn't afford to mess up, to make a mistake. Other people's lives were on the line and in his hands; his brothers, his friends, the city, and heck sometimes the world. It's not fair! It sucks!

Donnie's face scrunched up with defeat. It really sucks...

He felt a sob escape from his throat as the wall inside came crashing down. He buried his face in his arms as exasperated tears streamed down his cheeks.

Little did he know he was being watched by baby blue eyes from the lab doors.

"Donnie?"

Donnie froze and tried to gain his composure the best he could, he slowly lifted his head and held back a sniffle.

"Oh...hi M-Mikey."

Mikey took one look at his brother and sighed, his shoulders visibly sagged. He walked towards the purple turtle slumped in his chair. Donnie watched his little brother shuffle up and stand next to him, looking down into his eyes. Don felt a cry fill the room and he immediately wrapped his arms around his Mikey's body and cried into his plastron. Mike just rubbed the back of his brother's shell soothingly.

Donnie tried hard to keep the tears at bay but the more he tried, the more they flew out of him. Especially now that Mikey held him he couldn't help but cry. The youngest brother made it feel like it was okay for the genius to shed tears.

Donnie struggled with emotions. He was naturally an emotional turtle but he tried hard to keep it under control. He often got jealous at Leo's ability to keep feelings underneath and have a cool, clear head. Then there was Raph who just flew off at any emotion he felt. Don envied that as well. He wished he could just act on every feeling he got, but then he felt vulnerable.

Soon Donnie's tears subdued and he released from his death grip, wiping the moisture from his cheeks quickly.

Rule number one about consulting Donatello, if he cries, which is rare, don't talk about it. He bottles up his emotions, but he always ended up exploding eventually. Mikey would have to wait until he was okay before they could talk about it.

Mikey smiled sweetly and Donnie nodded his head and took a deep breath, telling his brother he was down weeping.

"You should get some sleep." Mikey said, concerned about the bags under the turtles eyes. Donnie shook his head,

"You sound like Leo."

"Wise turtle." Mikey chuckled.

"I can't sleep." Donnie said suddenly and stared into space, lost in thought.

Mikey tilted his head to the side waiting for Donnie to continue.

"My brain is too jumbled to sleep. I have too much going on in there." Donnie tapped a finger to his temple. Mikey nodded and looked at the clock. Don followed his gaze, 12:00. Mikey would probably be going to bed, he normally does at midnight. They looked at each other again,

"Will you be okay?" Mikey asked. Donnie smiled and nodded yes but secretly didn't want him to leave. He watched as his little brother stalked out of the lab. Donnie sighed; it felt good to cry, to pour out some of his frustrations. But it wasn't pragmatic, it wouldn't change the fact that he couldn't figure this out. He is still stuck on square one and making little progress. Crying felt weak and made him feel like a little kid. He wasn't allowed to cry. Leo doesn't cry, but Leo's reasons are different then his own. Leo is the leader and feels he can't show his emotions; which is just a stupid reason in Donnie's opinion. The intelligent turtle just doesn't like crying. He was the smart one, the inventor, the engineer. His brothers looked to him to fix everything, they relied on him to. He was vital to missions and plans and often had to be the one to save their shells. They thought he knew everything but he doesn't. It's just so much pressure and he is often an emotional wreck underneath. Right now, he's not acting like the intelligent turtle his brothers expect, or what he expects for himself.

Donnie closed his eyes and it felt good, however sleep still eluded him. It didn't matter much anyway because a door creaked open and he lifted his head; blinking in surprise, he stared at the walking junk pile that shuffled in.

A cup of coffee was the first thing Don noticed, then a pillow, two blankets, some comic books, a stack of food, a sketching book and a box of crayons. Crayons? Mikey hasn't used crayons in forever! Mike was an excellent artist, but he stopped using the waxy utensils and started to use pencils, charcoal, and some cool sharpies April got him for Christmas. Mikey shuffled in and plopped all the stuff on the counter next to Don's desk, then shoved some papers off for some butt room.

"What are you doing?"

"Keeping you company."

Donnie opened his mouth to respond but it was cut off quickly.

"If you can't sleep, I can't sleep." Mikey grinned and shoved out the new cup of coffee at Donnie which he gratefully took. Mikey noticed his quivering hands,

"How many cups have you had today?"

"Two..."

Mikey gave him a stern look.

"Okay maybe like seven." Don sipped the coffee and instantly felt better. Mm! freshly brewed, Mikey must have made him a new batch. The youngest turtle looked concerned as he flipped open his sketch book,

"Want to color with me?"

"No I need to work." Donnie said.

"Alright." Mikey nodded and picked up a green crayon and began to move across the paper. Donnie watched as the concentration etched his face. Pure joy of making line after line was evident as he turned the sketch book with the crayon. Each line was quick and crisp, Donnie wish he could draw like that. Sometimes he would draw inventions and ideas, but he was slow and used a ruler. Mikey made lines effortlessly and without thinking twice about it, already knowing how they would turn out.

Mikey noticed Donnie watching him from the corner of his eye,

"I love drawing."

Donnie snapped out of it and turned to his work, "Yeah?"

"It's relaxing; I can just pour my soul into it. Every line has a purpose you know? One small line can make or break a sketch. Everything has its place and use. They work together to create art. It's awesome!"

Donnie sighed and looked at his brother and smiled. He loved it when Mikey shared little things that surprised him, like the reason why he loved drawing. The purple clad turtle just thought he liked to sketch because he was good at it!

' I guess I can talk for a little bit.'

"Hand me those Doritos will ya!"

Mikey tossed the bag to him and gasped; a small smile curved on his face.

"First meal in two days and you want Doritos!? Not good brain food!" Mikey teased. Donnie opened the bag of Cool Ranch, his favorite.

"Don't tell Leo! He'll have a cow!"

"A cow huh? I wonder what sensei would say. Think we could keep it?" Mikey asked straight faced but a happy gleam in his eyes. Donnie chuckled at the thought.

"Where would we put it?"

"It can stay with Raph; he already snores so loud that we won't be able to tell the difference between the constant mooing and the cow."

Donnie felt a rumble of laughter burst out of him as he munched on the chips.

"I think his snoring is the real cause to my sleeping trouble!"

"Maybe we should get him a breathing strip! Then the entire planet could get some sleep." Mikey giggled.

"Do you honestly think Raph would wear that?" Donnie asked with a snicker. Mikey looked up from his drawing and smiled innocently, but his eyes sparkled with mischief.

"Not willing, no."

"You goon!" Donnie shook his head with a grin.

Mikey winked at Don and turned his attention back down to the sketch.

"Do you like these?" Don asked holding up a cool ranch Dorito.

"Only you do dude." He said without looking up from his drawing.

"Then why do you get them?"

"Because you like them."

Donnie blinked with surprise but smiled. He put the bag down and wiped his hands, time to work! He grabbed his pencil and...

"Whatcha think?" Mikey asked holding up his drawing. Donnie examined it and smiled.

It was of them. Mikey was hanging upside down with his Kusarigama chain like spider man. His smile was bright, confident and all Mikey. He was looking at Don, who was standing next to him with his arms crossed. Trying to look annoyed but a slight smile tugged his lips and his eyes were looking at his brother with love.

It was perfect.

"Mikey, you have a true talent."

"As do you."

Donnie looked up and his smile faded. Mikey sighed and ripped out a clean page of paper then put it in front of Don with a crayon.

"Draw" He commanded.

"Mikey, I am not an artist."

"That's okay, it's still fun!"

Donnie just stared at him.

"You put it on the paper, and then you move it around a whole bunch." His eyes were gleaming with laughter.

"I know what drawing is, thanks." Donnie mumbled and started to make stick figures. It was quiet for a while and Donnie knew Mikey was searching for words. He was about to make a speech.

"You are a genius Don," He eventually said, "but you are still just a turtle. You like cool ranch Doritos, you drink WAY too much coffee, you never sleep on time, you enjoy watching nova and you love your family deeply. No matter what you do, you pour all your energy into things. Whether it's experimenting, playing video games...or drawing." He chuckled as Donnie's tongue stuck out a little, working hard on as he viciously colored. "You're just a teenage dude, not a robot."

It was silent as Donnie thought it over. He knew what his brother was saying, that he has feelings and it's not a bad thing. Mikey's right, he should talk about it; it will make him feel better.

"I feel like a failure. I feel like everyone is counting on me. I feel stupid."

Mikey was taken aback by Donnie's words.

"I can't do this. I can't fix everything and I can't find this dumb retro mutagen." Donnie was pushing the crayon so hard it broke in half. He glanced up with surprise, "Sorry."

Mikey ignored it and said,

"Donnie, you aren't a failure. What about Thomas what's his gut, the guy with all the light bulbs?"

"Thomas Edison?"

"Yeah him, he failed a whole bunch right?"

"Well yeah...I see your point Mike, but I am not like him. He was a genius!"

"So are you."

"Not like that."

Mikey rolled his eyes,

"So? It doesn't matter! It doesn't matter if you don't figure this out Donnie! I mean it would help a lot of people but no one is expecting you to do something that you can't do. This is alien technology and we all know you are trying your hardest. Even if someone smarter came along and figured this out, I wouldn't care. You are my brother; I wouldn't trade anyone for you ever. Even if their genius powers built me a rocket to mars! We don't need them; we don't need a genius. We just need you."

Donnie didn't know what to say, so Mikey kept talking,

"We don't expect you to always fix things and of course you will make mistakes. I know how it feels to make mistakes and I know that it hurts." Donnie looked into Mikey's eyes. Oh Mike.

"You aren't going to fail okay? Even if it takes you forever, I know you and you will keep trying. You will figure it out. You will!" Mikey's voice was filled with determination and faith. He glanced at the silent brother, thinking hard about what was said. "You hear me?"

"Loud and clear." Donnie smiled and felt a weight lift off his shoulders. Mikey searched Don's eyes for a while and then he sat back in satisfaction, sighing a little bit.

"Late night chats make me hungry!" as he reached for some cookies.

"Everything makes you hungry!" Donnie giggled and then held up his drawing, "How's this?" It was a typical 'ocean with the island in the middle with two stick figures standing on it.

Mikey's smile was full of joy and awe,

"Wow Don! It's brilliant! Really! Fit for the Louvre*" Mikey said as Donnie laughed.

"Liar!"

"I like the octopus!"

"That's a sea star!' Donnie giggled and so did Mikey.

"That's what I said!"

"Did you know sea stars can regenerate their limbs?" Donnie said almost automatically.

"DUDE! New superhero! The Super Sea Star!

"Oh yes...truly striking fear in the hearts of villains everywhere." Donnie said sarcastically.

"Your right, it sucks...hm...Regeneration man? Limitless Limb boy? OH wait how bout..."

Donnie was deliriously laughing hard. It was 3 o'clock and they had been talking since noon, the slap happiness was hitting them hard. It honestly wasn't that funny, but Donnie just couldn't stop laughing at the burping contest that they decided would be fun. It was disgusting, but entertaining. Especially when running on only a few hours of sleep.

"Jeez Mike, if you don't be careful you'll blow up the city!" Donnie giggled.

"Oh you haven't seen anything yet!"

"I fear for the world." Donnie laughed as Mikey's face scrunched in concentration as he tried to force another belch. He held out his arms as if to make way for the oncoming storm, and a loud burp erupted from his mouth and rung throughout the lab. He truly is talented.

"Mikey you are a menace!"

"I do my best."

Their laughs died down a bit and Mikey cuddled into a blanket and hugged his pillow.

"Hey Mike, You know how you said you wouldn't trade me for anyone?"

"Yeah?"

"Well...I think I would trade you for a cleaning turtle; my labs a catastrophe!" Donnie smirked.

"We already have Leo! He's close enough!" Mikey's face looked serious but his eyes always give him away. Donnie chuckled at the thought of his older brother cleaning up his lab, mumbling complaints and comments about living with a bunch of slobs. To be fair the only real slob is Mikey, but Donnie and Raph do sometimes get a little messy.

Donnie sighed and felt the wave of sleepiness hit him; he could feel his eyes getting too heavy to remain open. He shifted in his chair and laid his head on his desk, feeling only seconds away from passing out. He felt good, he felt happy; and it was all because of his loving little brother.

What would Donnie do without him? He always was there from him and always knew how to make him laugh and smile. Even when the goofball came in the lab to annoy him, he loved the company. It was a good distraction to the endless thoughts running through his brain. Even though Donnie loved and prided himself for his intelligence, it was sometimes a burden. Mikey would always be there when Don was going crazy.

" Mikey, Thanks." Donnie felt himself slipping away into the bliss of slumber.

"You're always there to hold me up when I am losing my mind." Donnie yawns out as he gives into sleep. The poor guy was exhausted. Mikey smiled and threw his blanket over Don.

"Always."

If you didn't know the Louvre is a famous art Museum in Paris France. If you are curious, Thomas Edison's IQ ranges in like 145.
