Sarina sits in front of Donatello's computer, updating their project log. Her love of organization has led her to keep a running document outlining the projects they're working on and the ones they still need to get started on. It's a great way to help Donatello keep up with her, as she has a near unfailing memory.

"Changing the project log again?" Donatello calls as he enters the lab, a mug of coffee in each hand.

"Yes," she calls. She sighs a little, adding, "I've moved Timothy's retromutagen up in priority and added working on Destiny's hearing aids."

She goes still as she feels Donatello's plastron brush her back. He sets the coffee mugs down, reading over the document with a slightly furrowed brow.

"I wish I had a memory like yours," he says.

She tilts her head. "Your memory is astounding for someone with an organic brain. Do not wish to be different," she says. He purses his lips and she pushes the chair back. "Darling, you know you're brilliant, right?"

"Compared to you, it's hard to feel that way," he admits.

She shakes her head adamantly. "I find your intelligence far more impressive. I have the use of computers. I doubt that if I were human, I would be nearly as adept as you are."

His expression softens and he leans down, kissing her forehead. "You're the best. I'm sorry."

"Insecurities are a natural part of life and I am happy to praise you," she says. She reaches out to skim through the document again, eyes flashing. "In other things, I have the retromutagen for Timothy as the highest priority. Second is Destiny's hearing aids. Third is Pepper's retromutagen."

He groans. "I forgot about Pepper."

"We really should get on that," Sarina agrees. "Perhaps I will move it to the top of the priority list?"

"Yes, let's."

She does so. Donatello leans over her shoulder. "What else have we got?"

"Continue development of human patch," Sarina says, "and...place anti-Leonardo safety measures on the toaster?" She lets out a giggle. "What is that for?"

"I swear, it's for a good cause. I'm thinking either a warning bell that goes off if he tries to touch it, or," he says, "a forcefield generator around the outside that doesn't go off unless it senses Leo's approach."

"I do not understand why the toaster specifically requires such security."

"Because for some reason, Leo can't work that thing without hurting himself and others."

"Ah, I see. I feel his pain, though, as I am just as inept in the kitchen." She eyes the list again. "It's a shame that we must prioritize and focus on one or two tasks at a time. They all seem vital."

"I know, but if we did them all at once, we risk having plenty of unfinished projects," Donatello says as he pulls up his own seat. He eyes the sketches he left on his desk, detailing the human patches. "Human patches were on the list..."

"Yes."

He frowns, propping his chin on his hand. "It took so long just to figure them out, but they come with their own problems," he says. "They're useful, but they effect us in different ways that I didn't account for."

"Indeed," Sarina says, eyes flashing. "Destiny's deafness and general loss of heightened senses, your nearsightedness, and I've found that my memory is not as stellar when I wear them." She pauses. "Do not get me wrong, I am still intelligent, but my access to databases is gone and I dislike that greatly."

"So, basically, the patches work best for us turtles."

"Have your brothers noted any issues?"

"Raph said that his plastron chip shows up as a scar on his collarbone but...otherwise? No."

"Then your statement seems to ring true."

Donatello stares at the sketches, the notes, the dark smears from the multiple times he erased things only to write new ones and erase them again. He reads over the words, searching for any kind of inspiration.

He pauses on the work "cloaking." In the original notes, he said that the patch worked as a temporary cloaking device.

"Sarina," he says.

"Yes, dear?"

"The patches are like...a temporary cloaking device."

"Yes, unless I have misunderstood them."

"Why not find a way to make a permanent cloaking device, but...one that can be turned off and on as we please?"

Sarina slowly looks up from the computer, eyes flashing as she mulls over his words. "Hm," she murmurs. "Perhaps, something like the invisibility shields on the Kraang stealth ships?"

His eyes light up. "Brilliant, yes!" he says, already getting to his feet. He looks about the lab, hands patting aimlessly. "Yes, we...we have some of that tech saved from our scrounging, right? If we can reverse engineer it to create some type of illusion..."

Sarina continues watching him as he flits about the lab, still muttering to himself as he goes, and she smiles. She goes to the project list and adds another bullet point to the project regarding human patches.
