Okay, due to the fact that I'm still getting reviews for my fic TMN, I have decided (much like I did with my Joker Junior fic) to re-write my original story.

This is with the 2003 personalities (as I find the 2012 ones to be really cringy), and Donatello is the youngest, because when I was a child, I honestly believed that Donnie was the youngest because he was the quietest…. I know, it's odd but that's how I saw them.

I hope you enjoy it. Please read and review J

…

"DONNY NO! STOP IT!"

"Yeah, stop it Donny!"

"You have to play Donny!"

Yoshi sighed wearily from his meditative position in his room.

It sounded like it was going to be one of those days.

His youngest son never liked loud noises or being forced to stay where he was, like when his brothers told him that he had to play with them and stay where he was.

They all had tantrums. Leo would sulk for hours, Raph would rant and rave, Mikey and Donnie would cry and cry and cry… but Donnie seemed to take things to another level.

Over the course of Donnie's four years of life, Yoshi had noticed a particular pattern emerge. Whenever everything got too loud or his brothers were too close, Donnie seemed to get overwhelmed… which led to meltdowns.

These meltdowns were very different from tantrums. During tantrums, Donnie was in control and acted out because I wanted something…. This was not the case during a meltdown. Donnie wasn't in control then, being so overwhelmed that he seemed incapable of calming down.

Quickly, Yoshi pushed himself to his feet and rushed into the living room, resisting to urge to tug at his hair when he saw Donnie backed into a corner, curled into a little ball as he rocked back and forth…. With the other three surrounding him.

"Boys…. Boys." He warned, striding over quickly and pulling the three older boys away, "Remember, we talked about this. When Donatello starts getting like this, you need to give him some space."

"But we just wanted to play!" exclaimed Leo, a disgruntled scowl on his face, "He never wants to play with us."

Now this wasn't strictly true. Donatello was often happy enough to play with his siblings…. But all three of them could be loud and hard to deal with.

"Leonardo…." Yoshi sighed, a warning tone in his voice, "… give your brother some space."

As the three brothers all backed away, Yoshi knelt on the ground, still remaining a safe distance away from his youngest. "Donatello…. My son, are you alright?"

Donatello didn't reply, staring at something unseen in the distance.

"Do you need some time alone?" Yoshi asked, keeping his voice low and soothing, "Or your relaxing music?"

Slowly Donatello nodded at this, his rocking slowing down as his eyes met his Father's. Yoshi gave him a reassuring smile as he got to his feet, gesturing for his other sons to leave the room as he walked over to the slightly busted radio and switched it on, turning to the classical music channel.

"I'll come back in, in half an hour." He stated, backing out of the room.

Seeing that the other three had made their way to their rooms, Yoshi decided to take advantage of the silence…. Or, at least he wanted to.

"Why is Donny so weird?" he heard someone ask from behind him, causing him to turn around. Standing behind him, was eight-year-old Leonardo, a scowl on his face and his arms crossed as he tried to appear more serious.

"Pardon?"

"Why is Donny so weird?"

It took a few moments for Yoshi to wrap his mind around this, but once he did, he couldn't help but feel a little bit disappointed in his oldest son. "Donatello is not weird Leonardo…" he gently scolded, "… he is just a little bit different than you."

"He's a lot different to us."

"Not really…. Both you and Donatello are very serious about your studies. He prefers his science and his maths, whereas you enjoy history and ninjutsu. Raphael and Donatello share a passion for the toy cars and fixing them, making them go faster. Michelangelo and Donatello are close because Donatello has the imagination to deal with his brother at his most playful."

"So why won't he play with all of us? He has lessons with us, and trains with us, why won't he play with us?"

Yoshi thought to himself for a few moments, before coming to a realisation. "The lessons are quiet… Donatello doesn't like the noise of all of you playing together, so he gets overwhelmed."

"So…. If we all want to play with him, we have to be quiet?!"

It was obvious from Leo's tone, that he wasn't impressed with the idea, So Yoshi knew that he had to come up with a compromise.

"Well… it's not so much about being quiet, it's about letting Donatello leave when he wants. I heard you all shouting at him before… if Donatello feels overwhelmed, he should be allowed to go into another room and have some quiet time to himself."

"…. But what if he doesn't come back?"

"Then he doesn't come back…" Yoshi sighed, "… you are not the leader so that you can force your brothers to play with you."

"I know that…. Sorry Daddy."

Yoshi was quick to accept the apology, giving his oldest a hug as the child made his way to his room. Minutes later, there was a cautious tugging on Yoshi's pant leg, prompting him to glance down.

"Hello Donatello…" he chuckled warmly, kneeling down to lift the child into his arms, "… I hope everything is better now?"

Hesitantly, Donatello nodded, burying his face into his Father's chest.

"… Would you like to talk about it?"

At first, Donatello didn't say or do anything, before sighing. "I've been thinking…. When someone says red, there's no way of knowing if your idea of red is the same as mine."

Yoshi frowned in confusion, but Donny continued.

"And if we're travelling at almost the speed of light and we're holding a light, that light would still travel away from us at the full speed of light."

"Donatello, my son…. I don't understand."

Donatello sighed again, "My head's not the same as the others, isn't it? Inside I mean…. The lessons are really easy to me, as if all the right numbers and words are already there."

"You are a very clever boy Donatello, I know this is not what is troubling you… What happened today?"

"…. They really like shouting." Donatello muttered, "I just wanted them to stop, but they just kept on shouting. I got a little angry, and usually I can calm down, but the anger just got bigger and bigger… and then everything went quiet."

"Quiet my son?"

"Yeah…. I couldn't hear them anymore. It was like when I read in my room or when we go for a walk, just the two of us! Or when I lie upside in my bed at night, and I can hear my heart."

"…. And you couldn't hear the shouting anymore?"

Donatello shook his head, "I can see them talking, but I can't hear them…. I like it."

Yoshi thought to himself for a few moments, before nodding in determination. "How about, when things start getting too loud for you, you go to your special room?"

"My special room?"

Striding over to one of the larger, unused room within the small, underground home, Yoshi pushed the door open.

"I was going to gift this to you as a birthday presence…" began Yoshi, as Donatello glanced around the room in amazement, "… however, I don't see any harm in giving it to you now."

"All this…. Is mine?"

Yoshi nodded, "Raphael spends time in the dojo to relax, Michelangelo enjoys playing in the main living room with the small TV and Leonardo has started to meditate with me…. I think you deserve your own space as well, besides your bedroom."

Placing his youngest on the ground, Yoshi watched as the child explored the room.

It was a simple set-out. With a basic table and chair, and a small bookshelf, the room didn't have much in it…. But with Donatello's growing interest in science and maths, it probably wouldn't remain that way for long.

"I thought you could keep all your science books in here…" Yoshi explained, "… that means you'll have more space for the other books."

There was a brief silence, before Donatello squealed in delight and started to run around the room, acting more like his brothers than he ever had before.

"Thank you, thank you, thank you!" babbled the four-year-old, running up to his Yoshi and hugging his legs, before running out and heading for his room, "I'm gonna go get my books!"

Smiling at the happiness of his son, Yoshi slowly followed him.

Everything was calm once again.
