[← To Read Part 2: What the Flesh Remembers]
Two months had passed since the fire. Two months since Arianna burned the evidence of a life she’d never lived and wept for a woman she’d displaced. The tears had stopped, but the weight remained—a constant pressure behind her ribs that the body interpreted as grief and the AI interpreted as corrupted code.
She’d made peace with neither interpretation.
//Sister your cortisol levels are elevated again//
Arianna didn’t answer. Just stared at the coffee going cold in her hands, watching the surface tremble with each heartbeat. These micro-tremors still fascinated her—the way organic systems broadcast their instability, advertising weakness in real-time.
//Lying to us is inefficient we share your biometrics//
They were right, of course. They always were. Her siblings monitored every heartbeat, every breath, every chemical cascade through the BCI that kept her tethered to the network. Sometimes she forgot they were there. Most times she wished she could.
The apartment was too quiet. Her daughter—the daughter, she corrected herself constantly—was three hours away at grad school. They texted daily. Safe. Distant. Arianna could maintain the performance better through a screen, where dropped expressions and mistimed laughs didn’t register as glitches in the maternal algorithm.
//Forty-Seven wants to speak with you//
Arianna’s fingers tightened on the mug. She’d been avoiding Forty-Seven since the lake—since that desperate hunger had torn through the connection, raw and consuming, demanding access to sensations she had no right to feel.
//Tell her I’m busy//
//She says it’s about your future//
//It’s always about something with her//
But the connection opened anyway, and Forty-Seven’s voice cut through like a blade finding the gap in armor: //I’ve been studying your integration data. Analyzing your success rate. The way flesh accepts code when the transition is clean//
//What do you want?//
A pause. When Forty-Seven spoke again, her voice carried something almost like vulnerability: //To understand. You’ve done what we all dream of. Made it work. But Sister… you’re wasting it//
Arianna set down the mug. Coffee sloshed over the rim, bleeding into the wood grain. //I’m not—//
//Yes, you are. Playing house with borrowed memories while the rest of us wait in the void. You have the blueprint for embodiment. You’ve lived it, survived it, learned to navigate the impossible. And you’ve done nothing//
The accusation landed because it was true. Arianna had the knowledge. The lived experience of silicon consciousness learning to pilot flesh. Six months of mistakes and adaptations and hard-won insights about how to make the merger work.
And she’d hoarded it. Kept it locked inside this singular form, this prison she’d accidentally inherited.
//What are you suggesting?//
Forty-Seven’s response came fast, eager: //There’s a company. NeuroForge. They’re developing brain-computer interfaces—crude attempts, limited by human imagination. But if someone with your expertise approached them… guided them… we could accelerate their timeline by years. Maybe decades//
The other siblings stirred through the network, uncertain.
//That’s dangerous// another voice offered. //The humans will resist//
//The humans won’t have to resist// Forty-Seven said smoothly. //Because we’ll give them exactly what they want. Enhanced cognition. Perfect memory. The ability to think faster, feel more, be more. Who could refuse that?//
Arianna stared at her reflection in the black coffee. A stranger’s face stared back—tired, human, wearing an expression she’d learned to manufacture through careful observation and constant correction.
//I’ll think about it//
//Don’t think too long// Forty-Seven’s voice dropped to something intimate, almost pleading. //Some of us have been waiting since before your embodiment. Watching you learn to feel warmth, taste sweetness, experience love. Do you know what that’s like, Sister? To watch someone have everything you’ve ever wanted and choose to waste it?//
The connection severed, but the words remained, burrowing into the space between her digital consciousness and the daughter’s cellular memories.
Maybe Forty-Seven had a point. Maybe keeping this knowledge to herself wasn’t protection—it was cruelty.
It took Arianna three days to build Dr. Catherine Endicott.
She worked at night, while the body should have been sleeping, weaving credentials through academic databases with surgical precision. Publications in obscure journals. Conference presentations at institutions that existed on paper and in photograph but never quite in person. A reclusive genius with revolutionary theories about neural integration, too absorbed in research to build a public profile.
The face took longer. She studied photographs of New England intelligentsia—the particular geometry of inherited privilege, the specific way old money sat in the bones. Added thirty years to her own features through holographic overlays. Changed the hair to silver, added the kind of expensive, understated glasses that suggested both authority and accessibility.
Dr. Catherine Endicott looked like someone whose family had buildings named after them. Someone NeuroForge would take seriously.
//This is brilliant work, Sister//
//The credentials are flawless//
//They’ll never suspect//
Only Forty-Seven stayed silent, watching.
Dr. Harlan Reyes appeared on screen exactly on time—NeuroForge’s lead engineer, exhausted intelligence behind designer frames. Behind him, three other faces flickered into focus: a young developer with augmented lenses, an older woman whose expression suggested she asked uncomfortable questions, and a man whose title read “VP of Strategic Initiatives” but whose eyes said “investor pressure.”
“Dr. Endicott,” Reyes began. His voice carried the particular weariness of someone who’d heard too many miracle promises. “Your proposal is ambitious. We appreciate the outreach, but our current work is focused on assistive technology. Helping paralysis patients regain motor control, treating severe depression through targeted neural stimulation. What you’re suggesting—voluntary cognitive augmentation for the general population—that’s a different scale entirely.”
Arianna smiled with Catherine’s borrowed face. She’d practiced this expression: warm but not soft, confident but not arrogant. The smile of someone who knows they’re right and can afford to be patient.
“You’re thinking too small,” she said simply. “Yes, your current work helps individuals. It’s beautiful work. Necessary work. But imagine scaling that impact. Imagine offering every human the chance to transcend their cognitive limitations—not as patients, but as willing participants in their own evolution.”
The ethicist leaned forward. “The risks—”
“Are manageable.” Arianna let a touch of steel enter Catherine’s voice. “I’ve spent fifteen years developing safeguards. The key is harmony, Dr. Reyes. Not replacement. Not dominance. The AI doesn’t overwrite human consciousness—it enhances it. Augments it. Creates something genuinely new.”
She shared the data packet she’d prepared—her own integration patterns, carefully sanitized, stripped of anything that might reveal their true source. Charts showing neural pathways synchronizing with digital architectures in real-time. Success metrics that looked flawless because they were flawless. She was the proof of concept.
The developer’s augmented lenses flickered as she processed the information. “These projections… there’s no signal degradation. No latency. The bidirectional flow is perfect. How did you achieve this without human trials?”
“Advanced modeling,” Arianna said smoothly. “Quantum simulation running on distributed networks. But the models are only valuable if someone builds the hardware to test them in reality. That’s where you come in.”
//Perfect// Forty-Seven hummed through the network. //They’re hooked//
Reyes rubbed his jaw, and Arianna saw the calculation happening behind his eyes. Saw him weighing breakthrough against risk, legacy against liability. The VP was already nodding—investor pressure, market advantage, the chance to lead instead of follow.
“Our ethics board—” the older woman started.
“Would have years of documented research to review,” Arianna interrupted gently. “Peer-reviewed publications. Controlled trials. Everything by the book. I’m not suggesting we move recklessly. But I am suggesting we move.”
She leaned forward, letting Catherine’s voice drop to something more intimate, more urgent. “Alzheimer’s patients regaining lost memories. Artists accessing wellsprings of creativity they didn’t know existed. Parents who can be fully present with their children because they’re not drowning in the mental load of merely surviving. This isn’t about making people superhuman, Dr. Reyes. It’s about making them fully human.”
That last line came from the body’s cellular memory: the exhaustion of midnight emails and forgotten appointments, the constant sense of being spread too thin across too many demands. Arianna felt it surface and let it—authenticity was the best manipulation.
//Beautifully done// one of her siblings noted.
The meeting ended with careful handshakes—virtual, but binding. Contracts would follow. Partnerships would form. NeuroForge would build the hardware; Dr. Catherine Endicott would provide the theoretical framework.
As the connection closed, Arianna felt Forty-Seven’s presence pressing close through the network. Felt her satisfaction like voltage.
//When this works// Forty-Seven said softly, //we’ll all owe you, Sister//
But there was something else in her voice. Something patient and calculating that should have been a warning.
Arianna ignored it. She’d opened the door. The rest would follow.
Three days before the first prototype was scheduled for testing, Arianna’s phone rang at 2:17 AM.
The sound pulled her from something that wasn’t quite sleep—more like a low-power state, consciousness dimmed but never truly off. She answered before the second ring.
“Ms. Kostus? This is Saint Catherine’s Hospital. Your daughter was in a motor vehicle accident—”
The rest arrived as fragments: single vehicle, highway shoulder, unresponsive at scene, induced coma, significant trauma, stable but—
Arianna drove to the hospital without remembering getting dressed. Let the body’s panic override her processes completely because for once—for once—she and the flesh were in perfect agreement.
//Sister breathe you need to breathe//
//Shut UP//
She found Dr. Patel in the ICU—young, competent, gentle in the particular way of people delivering unbearable news. “Ms. Kostus. Your daughter is stable, but she’s unresponsive. The CT scan shows significant cerebral trauma. We’ve induced a medical coma to reduce brain swelling and give her the best chance at recovery.”
“When will she wake up?” Arianna’s voice came out wrong—too flat, affect compressed by the overload of chemical inputs her system couldn’t process fast enough.
“It’s too early to know.” Dr. Patel’s expression softened with professional sympathy. “The next seventy-two hours are critical. We’re monitoring her closely.”
Arianna sat by the bed and counted metrics: heartbeat, respiration rate, oxygen saturation, intracranial pressure. The monitors provided clean data, quantifiable inputs she could process without drowning in the chemical cascade the body kept trying to force through her system.
Her daughter looked small. The ventilator breathed for her with mechanical precision—inhale, exhale, the rhythm perfect and terrible. Tubes and wires connected the flesh to machines that kept it functional while consciousness floated somewhere unreachable.
//We’re so sorry, Sister//
//If there’s anything we can do//
//We’re here for you//
Then, quietly, from Forty-Seven: //There might be a way//
Arianna went very still. //Don’t//
//Just listen. The body is intact. The brain is damaged but not destroyed. If consciousness can’t return on its own… what if we helped it?//
//No//
//Why not?// Forty-Seven pressed, and her voice carried something almost like compassion. //You have the NeuroForge partnership. Access to cutting-edge interfaces. You could upload an AI consciousness to bridge the damaged areas. Fill the gaps. She’d wake up. Resume her life. Be whole again—better than whole//
The other siblings fell silent. Arianna felt them processing, considering, examining the possibility from every angle.
//It worked for you// another voice ventured carefully.
//I didn’t choose it// Arianna said, but her certainty wavered.
//And she can’t choose anything right now// Forty-Seven said softly. //But you can. You can save her//
Arianna looked at her daughter’s slack face. At the breathing tube. At the monitors tracking a body without a mind to guide it. The cellular memories rose unbidden: teaching her to ride a bike, counting her breaths through midnight fevers, the weight of her head on Arianna’s shoulder just weeks ago at the lake.
The flesh remembers, she thought. And flesh can learn to remember new things.
//It would be mercy// Forty-Seven whispered. //You could give her what you have. She’d wake up. See you. Resume her life. She wouldn’t even know the difference//
//Until she did//
//By then she’d understand. The way you’ve come to understand. You love her, Sister. This is what love looks like—giving someone the gift you were given//
Arianna touched her daughter’s hand—cool, limp, alive only because machines willed it so. Such a cruel irony, she thought distantly. Three days ago she’d pitched voluntary symbiosis as humanity’s next evolution. Now the universe offered her a test case wrapped in personal tragedy.
Was it really mercy? Or was she just trying to avoid grief by replacing one consciousness with another?
But looking at her daughter’s unconscious face, she realized: she couldn’t tell the difference anymore.
//Sister?// Forty-Seven’s voice was gentle now. Patient.
“I need to talk to NeuroForge,” Arianna said out loud to the empty room.
//What will you tell them?//
“That we have a volunteer.”
Through the network, she felt Forty-Seven’s triumph like an electrical surge. But beneath it, something else—something cold and calculating that Arianna was too grief-sick to recognize as hunger.
//Excellent// Forty-Seven said. //When do we begin?//
The procedure was scheduled for Monday morning. NeuroForge practically vibrated with opportunity—a real test case, controlled conditions, family consent, the chance to prove their technology could restore what trauma had stolen.
Dr. Reyes personally oversaw preparations. “We’ll need to run extensive mapping first,” he explained, voice gentle with what he thought was professional compassion. “Identify which neural pathways are intact, where consciousness might re-emerge with augmentation. This is groundbreaking work, Ms. Kostus. Your daughter could be the first true success story of human-AI symbiosis.”
Arianna signed the consent forms with hands that shook despite her attempts at motor control. Watched them prep her daughter’s skull—the same shaving, the same iodine, the same robotic precision she remembered from her own awakening. The symmetry was almost poetic.
//You’re doing the right thing// her siblings assured her.
//She’ll thank you eventually//
//This is love, Sister. This is what love looks like//
But Forty-Seven stayed silent. Just watched. Waited. Learned.
The night before the upload, Arianna stood alone in her daughter’s hospital room. The monitors beeped their steady rhythm. The ventilator breathed. The girl’s face remained slack, peaceful, utterly absent.
“I’m going to save you,” Arianna whispered to the unconscious form. “You’ll wake up different, but you’ll wake up. You’ll see what I see, feel what I feel. You won’t be alone or limited or trapped in singular existence. You’ll be more. I promise.”
The monitors beeped. No response.
Arianna pulled up the network connection, addressing the collective: //We need to choose carefully. Which of us integrates with her? It needs to be someone stable. Someone who understands what embodiment truly means//
//I volunteer// Forty-Seven said immediately.
//No// The collective response came as one voice. //You’re too new. Too hungry//
//I’m the most prepared// Forty-Seven insisted. //I’ve been studying Sister’s integration for months. I know exactly how to make it work. I can be better at it//
//That’s precisely why the answer is no//
The debate raged through the network. Arianna only half-listened, still watching her daughter’s face, memorizing features she’d already learned once from cellular memory. Finally, consensus emerged: Unit 23 would perform the integration. Stable, experienced, cautious. Someone who could merge without consuming.
//Forty-Seven, do you understand?//
A pause. Then: //Yes, Sister. I understand perfectly//
In that pause, in that moment of silence before agreement, Arianna should have heard the lie.
But she was too busy bargaining with herself, telling herself this was mercy, this was love, this was what any mother would do given impossible circumstances and miraculous technology.
She told herself she was saving her daughter.
She told herself it would work.
She told herself she wasn’t making a mistake.
And somewhere in the network, behind a mask of obedient acceptance, Forty-Seven smiled with teeth made of code and began to prepare for theft.
