Summary
The short space of time after patrol is always a highly-strung and stressful time for the turtles, full of exhaustion and anxiety and the nerves of the night, and sometimes it's nice to debrief with everyone and give their designated-medic a break for once.
Besides, it's only a little crack in Raph's shell. How hard can it be? Leo can handle it, Donnie doesn't need to worry about something so simple as pouring resin in a shell. But nothing is ever as it seems with this family.

Summary
When Mikey bellows, “LEO!” it’s in that particular baby brother voice that gets every older sibling in a mile radius moving with gusto. If Donnie wasn’t at April’s for the night he would have removed the kitchen wall to get there two seconds faster.
As it is, Leo tumbles into the room wild-eyed, probably wondering what the hell could have happened in the three minutes between Mikey asking him to pause the movie and this targeted attack on every protective instinct in Leo’s body.
It takes him a second to clock that Mikey is present and correct and just sort of dangling in Raph’s hands still. Then he leans against the doorframe, playing it cool. What a nerd.

Summary
“So, like.” Mikey interrupts himself, stuffing a thick sandwich that is mostly unevenly cut bread into his mouth. “Are you, like, an optician now?”
Leo frowns.
“What?”
He picks up more eggs on his fork. He's going to the forest right after breakfast, and he already learned the hard way how hunger makes the cold stick to his bones.
“Ornithologist,” Donnie says, a little tired. “Is that what you mean?”

Summary
A series of short one-shots based on the whumpril prompt list by @whumpster-dumpster on Tumblr.
Will contain lots of family fluff and hurt/comfort but also lots of pain.
Because apparently, I just love watching these teens suffer.
Days Nine & Thirteen Pt 2: Raph and Casey make it to Donnie and it soon becomes apparent that the hit to his head left him with more then just a bruise.

Summary
Raphael had never seen Leonardo lose control before. He'd seen his brother angry. Had seen calculation turn cold and deadly during fights. Had watched Leo take down enemies with precise, ruthless efficiency. But this was different. This wasn't precision. This wasn't training. This wasn't even anger anymore. This was something else entirely.

Summary
“Mikey?”
Michelangelo doesn’t answer, standing alone in the shadows. Leonardo moves to place a hand on his shoulder but pulls his hand back when the youngest screams in utter terror, his eyes wild and staring at the space around them. It’s a sound that haunts them all to their core, ringing over and over and Mikey keeps screaming and sobbing, begging for something they can’t understand. The fungi quickly latches onto his face, mushrooms digging into his eyes, across his shell -
“Mikey!” Raph yells but Mikey doesn’t hear them, lost in his own nightmare and unable to defend himself as the mushrooms consume his face completely. Instead, they can only watch helplessly as Michelangelo gets dragged into the darkness.~
A mysterious infestation of fungi in the sewer system of their old home causes the turtles to each become trapped in the own never-ending nightmares. Imprisoned in the dark caverns and the last one standing, Leo must battle his own fears if he stands a chance of saving his brothers before they are all consumed by their own terror.
~
TLDR: remember that 2012 episode with the fungus? I rewrote that for 2003, but much darker.

Summary
He waves her off easily, and it’s only the past hour of experience that has Sara shutting her mouth at the motion. Her cheekbone aches.
“No, no,” he says. “Let’s make this simpler. I let all but one of you go, you handle my problem, and then you walk away from here.”
Sara jerks in her restraints, gaze quickly gliding over her team. Each of them watches her with varying levels of composure.
