The gears inside of Donnie's head whirred at top speeds. He could literally feel steam rising out of his head as his left eye twitched constantly. His face went twenty shades of red in the matter of seconds, and the hand that gripped his wrench trembled. Every single vein popped, and his muscles tensed up.

He was done.

Absolutely done.

"MIKEY!" he shouted at the top of his voice as his eyes locked onto his current project, completely in pieces.

Gears, wires and bolts were scattered all over the table, and even on the floor. Weeks of work, gone. He didn't care how or why. All he cared about was tearing Mikey's head off.

"For the last time, my lab is off-limits. My things are not your toys! Same goes for Raph!" He screeched as he threw his wrench against the wall. A clang echoed through his lab, followed by silence.

Donnie strained his ears for a few seconds to see if he could hear anything. A faint sound of snickering that could be heard when he concentrated hard enough. His eye started to twitch at a more rapid pace.

Now, it was on.

If the two of them were going to be jerks, then he was going to make it very clear that he meant business. That was the fifth invention they destroyed this month, and he wasn't going to let it slide, not when they were off laughing at about it.

He turned and snatched up another wrench from his workbench. Then he stormed out of the lab, slamming the door behind him. Donnie knew they had to be around somewhere, and kept his eyes peeled. As he made his way through the lair, he noticed a lot of things he had recently repaired were already broken. Each step thumped against the concrete, and his anger continued to rise.

Oh were they going to get it.

Again and again, for years his brothers have constantly used him for their needs. Ever since their father died, Karai left for Japan, and April went away for college, he had been stuck with them.

The first two years were hard, but now, it was just unbearable.

Normally, it would have been Leo's responsibility to put the two in line, but at the current moment, he was out of commission. He had been gravely injured during the fight against the Shredder. Then again, being thrown off a building will do that to a person. It was a miracle that he even survived at all.

Now, Leo just struggled to keep himself together. He took their father's death dramatically, and there were times he just couldn't function. Donnie tried to be understanding. He really tried.

However, it had been three years. Enough was enough. The random spells of depression and anxiety needed to stop. They had to move on. He needed to move on.

A drawn-out sigh passed his lips as he marched up to the dojo. Perhaps he should see if Leo would do something about it, rather than just sitting around doing nothing. Once he reached the door to the dojo, he pressed his foot onto it and slammed it open. He nearly kicked it off it's hinges with his anger at an all-time high.

Then he stepped into the dimly lit room and scanned it with his eyes. Sure enough, his brother was in there. Underneath the tree, Leo sat in deep meditation. Donnie stared at him for a moment, but his anger was just too much to handle. If anything in these last three years, he developed a nasty temper that could rival Raph's, or sometimes, even nastier.

With three brothers to look after, two of which always grinding against his nerves, things like that tend to happen. It was just when his brother sat around doing nothing was when things would go sour.

"Leo!" He shouted as he stomped up to him in a fiery rage.

His brother refused to budge, remaining silent. The fact that his brother completely ignored him only grinded against his nerves. Donnie's reddish-brown eyes gleamed with fury as he shifted the weight of the wrench in his hand.

"Leo, I don't have the patience for this. Mikey, and maybe Raph, tore up my lab again. I'm done! Now are you going to do something about it, or am I? They won't like it if I have to deal with it." He ranted on in quick short breaths.

Again, no response.

Donnie wanted to take the wrench in his hand and bash it against his brother's skull, but logically, that would be considered misplaced anger. After all, Leo rarely left the dojo, only to go to his bedroom, or take care of some other necessity.

Of course he's not going to help me, Donnie thought to himself with distaste.

After glaring down at Leo, he couldn't stand the sight of his older brother anymore. With disgust, he spun on his heel and decided to pursue his other two brothers. After all, he could hear them laughing in the distance. His stomach tightened, and his eye continued to twitch. All those gears inside his mind were turning so fast that it made his skull feel on fire. He couldn't wait to get his hands on them.

Donnie made his way to the bedrooms. The ever-so-teasing laughter echoed from that direction. He readied the tool in his hand and sprinted. Once he made it to Mikey's door, he skidded to a halt and kicked it open.

Empty.

He stepped inside and glanced around. His reddish-brown eyes scanned the darkened pig-stye. No sign of his brother, but he could of sworn he heard the laughter emit from this room. A realization hit him, and threw a glare over his shoulder. Raph.

As he turned to head to the next room, he heard the laughter once more, fueling his rage. He picked up his feet and slammed Raph's door open as well. His jaw tightened, and the twitch refused to cease.

Raph's room was empty as well.

Out of frustration, he lifted the wrench and swung it at the door frame. The impact jolted through his arm, but he didn't care. He was going to find them.

He was sick of the games.

Laughter echoed throughout the lair, causing Donnie to twist his head towards the pit. They had to be somewhere close by. Shuffling his feet, he cleared his mind and focused on the sound. It was moving all over the place, and he knew his brothers were hiding in the shadows, taunting him.

However, the rage inside him continued to boil, spilling over the brim. He couldn't take it anymore, so he ran towards the center of the lair.

"Show yourselves. This is ridiculous!" He cried out, cutting the air with the tool.

His labored breaths filled the harsh silence.

Suddenly, he heard their voices echoing from the tunnel outside of the lair's entrance. A wicked grin spread across his face as fire burned in his reddish-brown eyes. He readied himself, gripping the wrench tightly in his hand as he stared down the entrance.

The laughter grew louder as they neared the entrance. Donnie heard Raph as well, and immediately he knew that he had also been in on it. As they turned the corner, he readied his muscles, preparing to pounce.

The moment they both came into view, he leapt through the air, slicing the wrench towards Raph's head. Just in the nick of time, Mikey pushed Raph out of the way. His brothers stumbled and gave him a bewildered look.

"Woah D, what's your problem?" Mikey asked as he cautiously raised his hands. A look of utter confusion shone upon his face, replacing the previous bewilderment.

Steam rose up out Donnie's head at the question as he regained his footing.

"My problem?" He sneered as he prepared to swing the wrench. "My problem is that you two boneheads trashed my lab and broke the invention I was working on!"

Then he took another swing at his brother, who flipped to the side.

"To make matters worse, you two had to play games with me!"

Mikey continued to evade Donnie's crazed swings. It was a lot of effort to control himself, because he really didn't want to hurt him. Raph on the other hand, he didn't mind making a few strikes at the taller turtle.

"What are you talking about? We haven't been in the lair all day!" Raph barked as he blocked a jab aimed towards his face.

Now all of Donnie's gears were turning so fast, that one actually fell of the track. He stumbled back and cringed. He could feel his mind breaking down as he tried to comprehend the situation. After all, his invention was fine before he left for his scavenge run. Wait, did he go on the scavenging trip? He did want a new bundle of copper wires, maybe a new batch of scrap metals, and even…

Suddenly, his thoughts scattered out and he realized that he needed to focus. Donnie gripped his head with his free hand. Every muscle trembled and he felt like his brothers were just trying to throw him off.

Finally, he snapped.

"You're lying! I clearly heard you two!" Donnie snarled as he lunged forward.

Raph sidestepped him and quickly got behind him. Then using the strength in his arms, he grappled Donnie, and put him in a headlock. The taller turtle tried his hardest to resist, even dropping the wrench to tug at the arm, but Raph's strength exceeded his own.

"Will you calm down?" He growled at Donnie.

"How am I supposed to calm down when you have me in a headlock?" The taller turtle gasped out in spite.

He continued to struggle, pulling and clawing at Raph's arms. Mikey took carefully thought-out steps towards him, his arms raised once more. Donnie's reddish-brown eyes locked onto him as he continued to resist his holder.

"He'll let you go when you calm down. Look D, we haven't been in the lair all day. So let's just calmly talk about it. Okay?" Mikey asked in a light tone with a sincere smile.

However, Donnie eased his eyes shut and continued to fight against the grip. He wasn't going to sit down and do anything with those two. They destroyed his things, played hide-and-seek with him, and now they were trying to deceive him.

Inside his mind, the gears continued to spin; one flew off, followed by another. His brain was literally melting and he couldn't properly string ideas together. What about his scavenge run? Wait no, there was always time for that. His invention that he worked many sleepless nights over? Well, that was in shambles and it was all their fault.

Then, Donnie heard it.

Emitting straight from Mikey was the faint sound of snickering. He knew it. They were messing with him! His eyelids flew open, and his rage energized him.

"Quit laughing at me!" He screeched as he dug into Raph's arm.

Raph could only hold him for so long and he could feel his hold starting to slacken. He tried his best to ignore the pain, but Donnie was relentless. His emerald green eyes shone with concern, but then he blinked as he shook his head.

"Look Mikey, we are going to have to do it again. I know I promised that we wouldn't, but he's just too out of it."

The youngest brother looked at the two struggling turtles and thought for a moment. His mouth became a hard line and he folded his arms across his plastron. Then he nodded with affirmation and sprinted off towards Donnie's lab.

As he waited for Mikey to return, Raph readjusted his hold the best he could and eased their bodies downwards. He was thankful that Donnie was skinnier and weaker than him, else it wouldn't work out so well.

However, his brother thought otherwise. Fear started to mingle with Donnie's rage. He didn't know what his brothers were planning, and frankly, it scared him. His heart rate elevated and his breathing quickened within the hold.

What exactly did he do to deserve this? He just wanted to have a normal day, but no, those two had to go and ruin it for him. Where was Leo? The one time he truly needed his brother, he was off hiding.

"Leo!" He cried in Raph's grip.

Before he could wait for his older brother, Mikey had returned with that familiar black gun. The gun he made. The very weapon he made for their self-defense, and now they were going to use it on him?

As the last gear in his mind struggled to stay on it's track, he felt a sharp pain shoot through his arm. He could feel the very drug he created spilling into his bloodstream, and instead of staying calm, Donnie panicked.

"I'm so sorry, D," his younger brother whispered.

Honestly, he didn't believe it.

Donnie moved his lips and tried to speak out, but his speech was slurred as he struggled to keep his eyes open. He just felt really exhausted, and he felt his weight pull downwards as Raph eased up on his hold. The last thing he knew, he was falling to the ground.
