Summary
Pomni and Jax will not address the elephant in the room. That being that they constantly end up in situations where they end up cuddling. But it’s not intentional, and it's not implicative, and it definitely doesn’t mean anything. So they will continue not addressing it.
AKA 5 times fic for platonic funnybunny cuddle piles.
...+1 for the show's finale.

Summary
He was no stranger to severing ties before they would cut too deeply. It was how he had always operated here; if you don’t let anyone hook into you, you couldn’t be torn.
Did this really sting that deeply for him to reconsider?
---
Jax isn't used to making or keeping friends. Or thinking of anyone else. Or caring about their opinion. Or thinking of himself as worthy of love.
Or possibly receiving it in return.

Summary
“Hey, did Donnie eat his breakfast?” Leo asked, staring down at the dishes in the sink and counting in his head.
“I thought he ate before us.” Miley frowned, sitting at the kitchen table with some paper spread around him and a pink panda plushie in his lap. He’d helped clear the table and wiped some of the syrup and milk splashes up; but beyond that he left Leo to it and instead settled in to sketch, and keep him company in the long arduous task. If Leo was lucky, he’d offer to dry after the first thirty minutes. “It looked like his favorite cereal moved.”
“That was me.” Leo had put the empty box back and everything. Which, now that he thought about it, hadn’t moved since the last time Leo had eaten Donnie’s favorite exclusive mail order only cereal. Which was the day before.

Summary
It was cold. Bone chillingly cold. Mikey wanted someone to reach out and hold him.
He didn’t deserve to be held.
What?
Finally, Mikey could breathe. He craved the sweet relief of oxygen coursing through his veins.
But the breathing was too fast. It was too fast and Mikey couldn’t stop it and- it didn’t sound like him. He didn’t sound like Mikey.
He didn’t feel like Mikey.
He felt fear.
He heard nothing.
He smelled copper.
Heck, he tasted copper.
And he wished he didn’t see.
But he did. And he saw the Kraang. Worse, the Kraang saw him. It’s eyes could shoot straight through Mikey’s skull with how intently it was staring.
Wait, it wasn’t just staring.
It was targeting.
And Mikey was hit with a tidal wave of fear and loss and horror and regret and
relief?
OR Mikey’s always been one to shoulder his brother’s pain. What happens when the family therapist begins to experience mystic empathy? New powers plus old habits die hard.- Language:

Summary
Donnie had always known he was a little off, even for someone who was a mutant turtle living in the sewers with his 3 turtle brothers and rat dad.
Donnie got along with his brothers just fine, for the most part, but sometimes they'd say something and he just wouldn't quite understand what they were talking about, or Leo would make a joke that left everyone in stitches while it flew right over Donnie's head.
He didn't understand why his brothers didn't love and appreciate technology as much as he did. Sure, they thought his tech was awesome and would praise him for his accomplishments, but whenever he wanted to rant and ramble about the latest thing he was working on and all the technical components within it he'd get awkward smiles and strange looks. It made Donnie feel like he wasn't quite right.
Then, of course, there were those awful times when some awful thing would happen, or when everything was too loud and bright and Donnie would just scream and rant and rave because it sucked, and he was hurting. Why was he in so much pain, why did he experience this when his brothers never seemed to have this problem?

Summary
He’d known about it well before Splinter kicked him out of his lab. How far back it went, he has no clear idea. Burnout is tricky. Sometimes he can tell the moment it starts to rear its head, and then he can go and decompress by skateboarding or playing video games, or by falling into the hole of a different hyper fixation until the feeling stops burning at his brain. Sometimes, though, it sneaks up on him and takes him by the throat, and the best he can do is just ride it out and hope he’ll crash before he melts.
“So a while, then?”
“…Maybe.”
______________________
Donnie may or may not be going through burnout. His family may or may not be worried. Who's to say, really?

Summary
Donnie hadn’t misinterpreted it, no, Raph had actually told him to stay away from Mikey. His own brother. For no reason.
Well, perhaps not for no reason…
Donnie turned quickly to his computer, typing in the query that had been bothering him since Raph had first mentioned it.
Alligator snapping turtle biology.
Within minutes, his suspicions — and fears — were confirmed.
The water wasn’t just getting to them, it was drawing out all their base turtle instincts.
It explained everything. His brothers' enjoyment of the water, Raph’s aggression, Leo being extra annoying, even Mikey becoming more possessive. His own longing to submerge himself, the building irritation that itched beneath his skin the longer he denied his instincts—---
During an intense rainy season, the lair begins to flood, and Donnie is the only one who can keep their home from sinking beneath the waters. It would be a lot easier to manage if the rain hadn't triggered their hindbrains to run wild.

Summary
Honestly? None of them take mystic as seriously as they should. Sure they respect it and are fascinated by it (excluding Donnie), but none of them really considered the dangers that it may hold for the four of them.
A fight with a mystic user is going to change that forever.

Summary
“You alright?”
Mikey’s looking at him. His eyes are searching, scanning him up and down, like a watchdog. Donnie’s in the middle of getting to his feet to work, and he can’t possibly open up to him. It’s stupid. Irrational. Deplorable.
Donnie offers back a pathetic grin. “I’m fine.” The words are quick, seamless. Mikey smiles something bright at him, the answer giving no one anything to think about, nothing to consider. Mikey is busy, busy like Donnie is, and he can’t bring himself to throw another thing onto the youngest brother.
He feels his shell pounding. Flesh ticking like clockwork. There’s no pain, not yet, just brass bright growing stains in his flawless techwear. No one notices.
Good. He’s got a lot of work to do.
///
Or, in which Donnie is a worker first and a person second.
(Or, in which Donnie convinces himself he is nothing more than a robot. He’ll work through the pain, work through the slashes on his shell, work through the migraines. His brothers, however, won’t stand for that…
…If they catch onto it, that is.)

Summary
There was nothing that Donatello wouldn't do for his family. They meant everything to him, they were his entire world, they were all he needed. It didn't matter what he had to do to keep them happy. To make sure they were safe.
Unfortunately, that also meant changing parts of himself his brothers didn't necessarily understand. Its what they wanted, so its what Donatello would do.
Or, five things Donatello changed about himself and the one time his family found out. Inspired by the song Perfect Machine by Starset
