Summary
Merging with a Technodrome has life altering consequences... or more specifically life ending ones. While dying is uncomfortable, awkward, (and a bit of a chore,) the idea of his family continuing on without his technical skills is unbearable. Literally the pineapple on his pizza. The concept is so grating that Donnie will do anything to make sure his family is taken care of once he's gone: Even if it means transplanting another version of himself from another timeline to take up the job opening.
In Casey's Timeline his Donatello died in an extremely convenient-to-obscure way. A body was never found and his death was never explicitly witnessed. The only reason they know Master Donatello "died" is because his circumstances were "inescapable" but Donnie is sure he can put up some air quotes. Removing this other Donatello from Casey's Timeline wouldn't change the future that has already happened or create a new timeline. So what's the harm in taking someone from a timeline that doesn't need them anymore?
Or: Donnie needs to replace himself before he dies at the young age of seventeen and Master Donatello becomes the candidate for that endeavor... by force.

Summary
“Casey Jones.”
“Yeah?” Casey replied, sounding like he didn't have any broken bones.
“How?” Donnie asked, starting to believe his maps weren't as accurate as he thought.
“How what?” Casey asked.
“How did you get down a twenty foot vertical shaft?” Donnie asked.
“Oh, that,” Casey remarked, like it was old news. An old foe. “A rope.”
Donnie could feel the cogs of his brain turning slowly. Still gummed up by social anxiety. “A rope? You’re laying line in my air filtration system now? Are you a cave explorer? Do you have a YouTube channel that you will one day unceremoniously stop uploading to?” he asked, perplexed.
“Laying line?” Casey asked. “Is that an old person thing, from the past? Like leveling up? What's a YouTube?”
Donnie huffed. “Yes, it’s an old person thing from the past. Cave explorers would wriggle down into cracks in the earth. They would bring a rope that would lead from the exit all the way in. That way they could find their way out by following the rope.”
“What’s the point in doing that?” Casey asked.
“What is the point in what you’re doing?” Donnie countered.

Summary
"I can't differentiate my tones right now," Donnie said, toneless. "I'm irritated but not at you."
Though Leo could have had the decency to wear a shirt given what Donnie was going through.
Leo nodded, like Donnie wasn't eating dinner at eleven at night on a Wednesday and hadn't even bothered to heat up the dehydrated meat dish before consuming it. "What are you irritated about?" he asked, eyes flicking from the plate of food to Donnie's eyes. Knowing he wasn't going to eat it and likely debating how willing he was to fight over it.
As if timed comically his glasses slid a little down his face forcing him to push them back up with a harsh finger. "Having a body."
"Want to elaborate?" Leo asked, sliding his sandal from the inside of Donnie's right ankle up to his knee, "Is there something-"
The sudden jerk, churr, and dropping of his fork perked Leo right up.
A cocky grin spread over the slider’s face. "Oh you're horny," he whispered, closing his eyes and smelling the air.
Donnie clapped his knees together on Leo's pesky foot.

Summary
Cassandra Jones stood before him with the baby held out. Its chubby legs pedaling in the air, eyes wide with curiosity. A gurgling noise came from its throat. Donnie pressed back further in his chair, almost pulling up his old notebook as a shield.
“He has to meet his Uncle Donnie,” Cass said, handing Donnie the baby and grabbing his notebook off his lap. She put it on another chair nearby.
So.
Donnie was holding a baby by the armpits.
First impression was that it was lighter than he thought it would be. Nineteen pounds by his guesstimation. Donnie’s hands were huge in comparison to the baby. He was so fascinated by how small the kid was that when the baby’s hands grabbed his thumbs he couldn’t be upset about the wet saliva feel. He was wearing a jade green onesie with a tyrannosaurus rex on it.
“Where did you even get this?” Donnie asked, turning the baby to look at its small ears. The baby had black hair that kind of stuck up in all directions. “Just curious.”
From across the room next to Leo, Raph leaned down and asked, “Why is he rotating Junior?” To which Leo shrugged.
“He came out of me, you weirdo!” Cass snapped.

Summary
Purple chomped and yanked their head side to side. Their skull was grabbed and their jaw popped open. Another Hand squeezed their arms down and before Purple knew it they felt something squirt out of their tail.
“Seriously? Not you and the snapper!”
“Oh I'm going to pee myself! Great job! Super soldiers that can musk on their enemies!”
“Erg..”
Purple's breathing had rapidly increased. They released something else from between their legs. Something belonging in the trash corner of the cage with Blue. The Hand made another noise and this time Purple was dropped, landing on firm ground with a slight give.
“I was just moving you and your emotional support defect to a new, larger cage. And you poop on me? You poop on the great Baron Draxum?”
“Stop, stop, my sides hurt, ha ha ha ha HA!”

Summary
By eight thirty the lair was running on generator power and Donnie’s ears were ringing so loud he couldn’t even hear the baritone of the motor thrumming out in the open sewers. Note vibrating on the handle because no twin had returned home to rip it off with a roll of his brown eyes before depositing the original propane tank nearby. Donnie couldn’t hear Mikey’s voice as he asked about Leo, he couldn’t feel Raph’s hand as they brought him into the lair to warm up his frozen fingers.
Someone else moved Donnie’s mouth and made his vocal cords vibrate into the open air of their home. Someone else stood in the doorway of their father’s room begging their dad to get out of bed because Leo was missing. Someone else felt the world caving in because all the things that were supposed to be unimaginable were happening right now.
As if panic could knock back a respiratory infection Raph and Mikey hooked the TV up with Donnie’s numb help. The weather report was worse than they last knew. That blizzard that was originally projected to hit tomorrow by one in the afternoon would be here at their doorstep much earlier.

Summary
“While this has really inflated my ego,” Leo said, sitting down on the sofa next to him, “Giving you head so good that half our camp goes down with you- what the hell D?”
“I tried to say something but too much blood was in the wrong head and not enough was left in the right head.” He tilted to the left and leaned against Leo.
That big clunky metal arm wrapped around his shoulders. Protective, and worse; Concerned. “So I'm prescribing you food and water.” Leo's voice was airy and not to be argued with. “I shouldn't have to but I am enlisting Mikey and Casey to pester you to eat. Got it? You know how much time Casey spends with me he is trained in Annoying Donnie 101.”
“Understood,” Donnie sighed.
It seemed like the news was spreading that Donnie was okay. People and Yokai weren't standing over dead in their tracks Metalheads with pinched expressions.
Leo hooked his finger under the mug clutched in Donnie's hand. Helping it along to his mouth. He had the common sense to wait until Donnie swallowed to add, “And I'm prescribing weekly blowjobs.”

Summary
“You may have felt special because Leo is skilled in that- but you were not, you were easy,” Donnie snarled. “I selected you for that reason-”
“Now hold on you sick fucker-”
“No,” Donnie said louder, looking down at Travis now and opening his faceplate to show he was there in the flesh. The reaction was gold. Donatello was performing this live, no longer in stereo from the hanger and speaking through a metal zombie. “See if I was a sick fucker,” Donnie spat, “I might derive some sort of sexual gratification watching my brother fuck only those I allow him to. I might watch him complete that act through one of my many cameras without his knowledge.”
This was what he wanted to spread. His hatred for Leo and their fucked up dynamic. Travis wasn’t mad now, he was scared. Donnie was not angry because Travis landed a hit on his drunk brother, Donnie was angry Travis got in the way of him getting off tonight. “So now that I have made it clear I am essentially the one that pursued your partner through a mindless drunk puppet for my own amusement- where do we stand?”

Summary
Leadership training, in a jungle, alone, because that’s a set of circumstances that will make a better leader. What if Leo was sent away for a different reason? What if he was sent away to heal under the guise of “leadership training”? A year and eleven months ago Leo started acting strange. A year and nine months ago he was sent to Central America. A year and three months ago he was supposed to come home. A year ago he stopped writing. Two weeks ago he returned.
Now Leo’s back and his brothers question how he will fit into their lives now that he’s home and whether they should try and integrate him into their relationship. The only problem is the brother that left for training wasn’t the brother that returned, and now the story of why Leo was sent to Central America isn’t as cut and dry as they previously thought.
