Chapter Text

Day One

Before the silence, there was noise.

Not the noise of a city rebuilding after the sky had opened and the laws of physics had briefly become suggestions. Not the noise of emergency sirens, news anchors, Justice League debriefings, or the endless murmur of heroes saying names like prayers because names were all that remained when bodies did not. That was external noise. Tim Drake-Wayne could mute external noise. He had built his life around filtering it, prioritizing threat signals, and discarding everything else as nonessential input.

This noise was internal.

It was static in the skull. It was the high, thin whine of a mind refusing to process an impossible result. It was grief attempting to become a feeling and being rejected at the gate because Tim had no operational use for grief. Grief was not a strategy. Grief was not a protocol. Grief did not retrieve missing persons, reverse cellular collapse, reconstruct destroyed tissue, or force a universe to admit it had made a mistake.

Therefore, Tim did not grieve.

He worked.

The absence had mass. That was the first problem. The space next to him remained occupied even when no one stood there. His peripheral vision kept building Conner Kent out of darkness: a shoulder leaning against the Cave railing, a boot propped obnoxiously on the Batcomputer console, a flash of black hair in the chrome reflection of a medical tray. But absence could not have mass. A void could not generate pressure. Pain without a wound could not be categorized as physical injury, and if the injury was not physical, then the treatment tree became imprecise.

It was not a problem to be solved.

So could it be called a problem at all?

Why was it not solvable?

The question repeated until it stopped sounding like English and became a machine command.

He sealed himself in a forgotten sub-level beneath the Batcave, one of Bruce’s obsolete contingencies from an era when every threat was met with another locked room and another system no one else was supposed to know existed. Tim knew because Tim catalogued everything. The room had once stored confiscated alien biotech and Cold War medical equipment. By the end of the first day, it was a genetics lab.

The transformation was not elegant. Nothing about grief was elegant, even when dressed in sterile gloves and machine-readable labels. Tim dragged a Wayne-R&D bio-gel chamber out of climate-controlled storage, rewired a Kord Industries gene-splicer with a soldering iron in one hand and a half-cold coffee in the other, and built a closed-loop network from components Bruce had decommissioned because they were too dangerous, too invasive, or too difficult to explain to the board. The air became cold, dry, and chemical. The old dust burned away under UV sterilization arrays. The room began to smell like ozone, antiseptic, overheated processors, and denial.

At the center of the lab, beneath a ring of surgical lights, was a single sealed vial.

Conner’s blood.

The sample had been collected months earlier after Metallo. Tim had kept it under the guise of analysis. The lie had felt thin at the time. Now it felt prophetic. There was so little of him left in the world that Tim’s hands shook when he logged the vial into the system.

He corrected the tremor by clenching his fingers until the knuckles hurt.

Pain was useful. Pain produced focus.

He loaded the sample into the sequencer.

// PROJECT CHIMERA - CLONING ATTEMPT LOG: 001

// DATE: xx.xx.xxxx

// SUBJECT: KAL-EL/LUTHOR HYBRID TEMPLATE (K-01)

// OBJECTIVE: Replicate stable cellular division from archived blood sample.

// PROTOCOL: Cadmus Protocol Gamma-7 (Modified).

// RESULT: Initial mitotic division successful for 12 minutes.

// FAILURE EVENT: Catastrophic telomere degradation; chromosomal fraying; loss of membrane integrity.

// STATUS: FAILURE.

For twelve minutes, the cells multiplied.

For twelve minutes, Tim stood perfectly still and watched impossible green lines climb across the screen. The data looked clean. The first mitotic event completed without the ragged chromosomal drag he had expected. The second followed. The third.

A part of him, small and animal and humiliated by its own need, whispered, Come back.

Then the line dropped.

The cells did not merely die. They unraveled. The telomeres shredded, the chromatin loosened, and the sample collapsed into inert biological noise. On the magnified feed, the residue looked gray.

Failure.

Tim inhaled once. Exhaled once.

A result was not a verdict. It was a data point.

He adjusted the nutrient medium and began again.

// PROJECT CHIMERA - CLONING ATTEMPT LOG: 002

// MODIFICATION: +3% amniotic protein concentration; increased electrolyte support.

// RESULT: Stable division maintained for 78 minutes.

// FAILURE EVENT: Spontaneous apoptosis cascade; mitochondria triggered programmed self-destruction.

// STATUS: FAILURE.

Seventy-eight minutes was better than twelve.

Progress was not hope. Hope was volatile and metabolically expensive. Progress was measurable.

Tim archived the data.

Day Two

The lab became his world by process of exclusion. Everything outside it was too imprecise. The Manor had voices. The Cave had footsteps. The city had weather, traffic, crime, and all the messy human continuity that insisted on moving forward without Conner Kent. The lab had variables.

Variables could be controlled.

The hum of the air purifiers took on the rhythm of an artificial ocean. The centrifuge clicked every thirty seconds. The sequencer breathed hot air against the underside of the console. It was almost calming, if Tim did not let himself think of Titans Tower, of the reactor hum beneath the dormitory floors, of Conner complaining that Tim’s equipment sang him to sleep better than any lullaby.

The comm on his wrist buzzed seven times before noon.

Dick.

Tim muted it.

The pneumatic tube from the Manor chimed at 13:04. Alfred sent down soup, sandwiches, water, and a note folded with the kind of precision that could cut a man open.

Master Timothy, the dead do not ask us to join them.

Tim turned the note facedown without reading it twice.

He wrote new code instead.

The Cadmus files were incomplete, corrupted in the places that mattered most. Experiment Thirteen had succeeded after twelve failures because someone had discovered a stabilization matrix that the surviving files referred to only as “the field harmonization event.” Tim did not have the original matrix. He had fragments, autopsy-adjacent data, Luthor patents buried beneath shell companies, and the particular arrogance to assume that if he could not find the missing variable, he could build one.

Conner’s tactile telekinesis had always been described as a field, but that was imprecise. It was more like a bio-electric negotiation between body and world: touch became command, command became force distribution, force distribution became a boy who could lift a bus by the bumper without ripping it in half. If the field stabilized Conner at the macro level, perhaps a simulated resonance could stabilize him at the cellular level.

Perhaps.

// PROJECT CHIMERA - CLONING ATTEMPT LOG: 011

// MODIFICATION: Growth algorithm adjusted to simulate low-amplitude bio-electric field resonance (v.1.2).

// RESULT: Accelerated cellular growth for 93 minutes.

// FAILURE EVENT: Uncontrolled mutation; asymmetrical tissue formation consistent with Bizarro-type cellular logic.

// CONTAINMENT: UV sterilization and acid flush.

// STATUS: FAILURE.

The thing on the microscopic feed pulsed.

It was not Conner. Tim knew that with an intensity that made bile crawl up the back of his throat. It was a mockery built from bad math and worse desperation, a clump of tissue attempting to organize around power without personhood. A mouth began to form where no mouth belonged. It opened once.

Tim flooded the dish with sterilizing light.

The guilt came after.

It always came after, when the immediate danger had been categorized, contained, and terminated. It arrived like delayed pain after a fight, when adrenaline ebbed and the body finally reported the broken rib. Tim gripped the edge of the counter until his hands went numb.

“Not him,” he said to the empty lab.

The room did not answer.

He scrubbed the feed, marked the attempt nonviable, and returned to the code. The problem was the Luthor sequence. It had to be. Kryptonian DNA resisted replication because it did not belong to Earth, but it obeyed itself with frightening elegance. The human portion should have stabilized it. That was the point of hybridization. But Luthor’s genome was not a stabilizer. It was a hostile takeover written in nucleotides.

Tim opened a new report and typed with fingers that felt detached from his body.

// PRELIMINARY GENOME ANALYSIS: K-01

// K-SEQ: Solar-reactive, high-density, regenerative, resistant to synthetic culture environments.

// L-SEQ: Aggressive promoter activity; abnormal mitotic acceleration; elevated regulatory dominance.

// OBSERVATION: L-Seq does not integrate passively. It attempts to govern adjacent transcriptional behavior.

// WORKING HYPOTHESIS: Cellular failure is caused by intra-genomic competition between K-Seq and L-Seq.

// PSYCHOLOGICAL NOTE: Remove subjective language from future reports.

He stared at the last line for a long time.

Then he deleted it.

Day Three

By the third day, sleep deprivation began changing the architecture of the lab.

The walls lengthened when Tim was not looking directly at them. The hum of the machines developed harmonics. Once, while calibrating the sequencer, he heard Conner laugh with such clarity that he dropped a pipette and shattered it across the floor.

“Dude,” the memory said, bright and alive, “you should see your face when something breaks. It’s like someone murdered a spreadsheet.”

Tim stood over the broken glass until his breathing returned to baseline.

Auditory hallucination. Expected after seventy hours without sleep. Not relevant.

He cleaned the glass.

The next protocol attempted to suppress the Luthor-specific loci. If Luthor was the poison, then reducing expression should allow the Kryptonian sequence to dominate. It was clean logic. Brutal, maybe, but clean.

// PROJECT CHIMERA - CLONING ATTEMPT LOG: 027

// MODIFICATION: L-Seq suppression matrix applied; target loci methylation induced.

// RESULT: K-Seq rejected nutrient medium within 2 minutes.

// FAILURE EVENT: Immediate cellular necrosis; total culture loss.

// STATUS: FAILURE.

Tim stared at the dead cells.

The two halves needed each other.

That was the paradox. Conner had spent so much of his life terrified that one half of him invalidated the other, and here was the proof that he had only existed because the contradiction held. Kryptonian power and human arrogance. Alien sunlight and a billionaire’s bloodline of ambition. A weapon that had chosen kindness. A clone who had become more real than the people who made him.

A memory surfaced with surgical cruelty.

The Kent farm. Late afternoon. Cornfields moving like water. Conner on the porch steps with his elbows on his knees, not looking at Tim.

“What if there’s a part of me that’s like him?” Conner had asked.

Tim had not needed to ask who him meant.

“You’re not Luthor.”

“But what if I am?”

“You’re Conner.” Tim had said it like a theorem. “That’s the observable fact.”

At the time, Conner had smiled.

Now Tim wondered if certainty had been another kind of cruelty. He had treated identity like data because data did not frighten him. But Conner had not been asking for proof. He had been asking to be held.

The realization was useless. Late data could not alter the original event.

A knock came at the sealed lab door.

“Master Timothy?” Alfred’s voice was softened by steel and distance. “It has been three days.”

Tim did not move.

“You need rest.”

No. Rest was surrender. Rest was the place where the mind lowered its defenses and let images in. Rest was Cassie screaming. Rest was Superman’s hands shaking. Rest was Conner’s face too still.

Tim increased the volume on the internal speakers until the machinery swallowed Alfred’s voice.

Day Four

By the fourth day, the failures required organization.

Tim built a table because tables were containers, and containers implied limits. If the failures could be sorted by protocol variant, maximum viability, and cause of collapse, then they were not a swarm. They were not accusations. They were not ninety-nine small deaths wearing Conner’s stolen blueprint like a mask.

They were rows.

Tim sat back and looked at the table until the words blurred.

The pattern was insultingly clear. Every attempt failed at the point where the two dominant genomes tried to decide which one was in charge. The Kryptonian sequence wanted a sun. The Luthor sequence wanted a throne. The culture medium could provide neither, so the cell became a battlefield.

“Arrogant,” Tim whispered. “Even his DNA is arrogant.”

The rage came cold. It did not feel like the rage he had seen in Jason, bright and bloody and outward-facing. It felt like liquid nitrogen being poured behind his ribs. He pictured Lex Luthor smiling as though Conner had always been property, as though a boy could be reduced to intellectual property with good enough lawyers and enough contempt for the soul.

Tim swept a row of beakers off the bench.

Glass exploded against the floor.

For three seconds, the sound was satisfying.

Then the silence returned, and in the silence Tim saw Conner sitting on the counter, boots swinging through broken glass that did not cut him because he was not there.

“You know smashing the lab isn’t very scientific, right?”

Tim closed his eyes.

Hallucination. Visual this time. Expected. Non-actionable.

“You’re not here,” Tim said.

“Yeah,” Conner’s ghost said, softer. “That’s kind of the problem.”

Tim opened his eyes. The counter was empty.

Day Five

On the fifth day, language began to fail.

Tim discovered he had been speaking to the chamber only when his voice recorder played back eight minutes of whispered explanation he had no memory of making. He listened to himself describe the L-Seq as “territorial,” the K-Seq as “starving,” and the growth medium as “afraid.” Then he stopped the recording and deleted it because machines were not afraid and genomes did not want.

People wanted.

Conner had wanted so much. Ordinary things. A name that was not a serial number. A family that did not flinch from how he had been made. A future boring enough to include bad movies, laundry, and arguments about whether sunglasses counted as indoor wear if they were iconic.

The lab did not want. The chamber did not care. The cells divided or they did not.

Tim envied them.

At 18:23, Cassie sent a message.

‘You don’t have to answer. I just need to know you’re alive.’

Tim stared at the text until the screen dimmed.

He did not answer because alive was a more complicated category than Cassie intended. His heart was beating. His hands were moving. His brain was consuming glucose and oxygen at unsustainable rates. But he had left parts of himself at the tower. They had been caught in the same discharge, the same impossible flare of cosmic machinery. Some versions of Tim Drake-Wayne were dead. Some were missing. Some were in this lab, wearing gloves, trying to manufacture a universe where Conner Kent did not leave.

Alive was not precise enough.

He ran the next protocol.

// PROJECT CHIMERA - CLONING ATTEMPT LOG: 071

// MODIFICATION: Synthetic trophoblast scaffold introduced; reduced K-Seq radiation demand.

// RESULT: Surface adhesion achieved; initial blastomere symmetry promising.

// FAILURE EVENT: L-Seq hyperproliferation; scaffold invasion; malignant overgrowth.

// STATUS: FAILURE.

The malignant culture grew beautifully for nine minutes.

That was the worst part. Some failures were ugly immediately, wrong in ways that made termination feel like mercy. This one was beautiful. The cells organized into elegant spirals, each division precise, each membrane catching the amber lab light like stained glass. For nine minutes, Tim let himself imagine that beauty meant survival.

Then the growth curve turned vertical.

Cancer was just a form of cellular immortality without ethics.

Tim terminated it.

He slept for eleven minutes that night, sitting upright against the base of the chamber. In the dream, Conner stood on the other side of the glass and knocked from the inside.

Day Six

By the sixth day, the blood sample was almost gone.

Tim lined the remaining aliquots across the bench in order of viability. The row looked ceremonial. A vigil of tiny red reliquaries. He despised the part of his mind that supplied religious imagery, but the comparison remained. He had grown up around Batman, not gods, and yet here he was constructing an altar under the earth.

He reviewed the math again.

Without the original Cadmus matrix, stable replication was statistically impossible. The word impossible used to offend him. Now it simply sat there, squat and immovable, like a stone in the center of his chest.

The computer recommended rest.

Tim disabled the recommendation.

The computer recommended hydration.

Tim disabled that, too.

The computer asked whether he wanted to enable emotional wellness protocols built into the Wayne medical suite.

Tim stared at the prompt, laughed once, and closed it hard enough that the keyboard cracked under his fingers.

Then the memory came.

Not the tower. Not the death. Something smaller, crueler because it was soft.

Rain against Titans Tower glass. A terrible science-fiction movie playing too loudly because Conner insisted explosions improved when no one could hear the dialogue. Conner’s head in Tim’s lap, heavy and warm, his hair damp from a shower, his fingers absently tracing the seam of Tim’s sleeve.

“You ever think about it?” Conner had asked.

“About what?”

“After.”

Tim had looked down. “After what?”

Conner had gestured vaguely at the room: the uniforms, the comms, the waiting emergencies, their whole life organized around impact reports and blood type compatibility. “After all this. When we’re not... this.”

Tim had given the only honest answer he knew how to offer. “Sometimes.”

“What does it look like?”

“Quiet,” Tim had said. “Probably boring. You’d hate it.”

Conner had smiled with his eyes closed. “Nah. Not with you.”

The memory hit like a defibrillator.

Tim bent over the console, breath shaking, and for one dangerous second the lab vanished. He was back on the couch. He could feel the weight of Conner’s head in his lap, the damp warmth of him, the ridiculous trust of a boy made in a lab who still believed in a future soft enough to hold them.

He could not give up on that.

He prepared Test #100 with hands that were no longer steady.

The sterile field was compromised before he noticed the first tremor. His vision tunneled. Sweat gathered at his hairline from the heat thrown off by the processors. A tear escaped when he blinked, furious and hot, and he wiped it away with the back of his gloved hand. Salt, water, skin cells, trace proteins. A human storm reduced to chemistry.

One microscopic droplet fell.

It did not land in the main dish. The main dish was sealed. Tim’s protocols were too good for that. It landed on the auxiliary trophoblast culture staged for comparison beside the active sample, the one he intended to discard after the run. A control. A nothing. A sterile environment made temporarily human by accident.

Tim never saw it.

He was looking at the main monitor when the cells began to divide.

Day Seven

By Test #100, Tim was a wreck shaped like a person.

His eyes were bloodshot. His hands trembled badly enough that the fine motor correction in his gloves kept firing. His thoughts came in clean lines and then shattered at the ends. He had tried everything: Cadmus reconstruction, Luthor promoter suppression, Kryptonian solar simulation, mRNA buffering, synthetic field resonance, trophoblast scaffolding, and all the desperate hybrids in between.

The conclusion remained.

The chimeric DNA was a miracle. A one-time event. A biological impossibility that had briefly become a boy.

Tim could not replicate it.

He watched Test #100 hold for six minutes. Twelve. Forty. Ninety.

Hope rose like nausea.

Then the markers shifted.

// PROJECT CHIMERA - CLONING ATTEMPT LOG: 100

// SUBJECT: KEL-EL/LUTHOR HYBRID TEMPLATE (K-01)

// OBJECTIVE: Replicate stable cellular division using integrated modifications.

// RESULT: Initial stability achieved; genetic drift index rising.

// WARNING: Drift Index exceeds 10.0; cascade failure imminent.

// STATUS: CATASTROPHIC FAILURE.

The graph fell.

There was no drama to it. No explosion. No final scream from the machine. Just a green line sloping down, then flat, then the clinical confirmation of death rendered in a font Bruce had once chosen for readability.

Tim’s body folded around the loss before his mind caught up.

He pressed his forehead to the console. The metal was warm. His breath came in short, ugly pulls. For seven days, he had not grieved because grief had seemed like surrender. But the body was not interested in philosophy. The body knew loss. It knew cortisol, tremor, salt, muscle fatigue, and the neurological exhaustion of a brain forced to look at the same impossible fact until fact became wound.

A sob tore out of him.

He hated it. He hated the sound. He hated that it did nothing. He hated that somewhere upstairs the world continued, that Alfred would still make tea, that Gotham would still need saving, that the sun would rise without asking permission from the dead.

“I’m sorry,” Tim said.

He did not know whether he was speaking to Conner, or to the failed cultures.

The answer was silence.

After a long time, he sat up.

His face felt strange. Tight with dried tears. His throat hurt. The lab looked smaller, meaner, stripped of its terrible sanctity. It was no longer a sanctuary of science. It was a room where he had done monstrous things because he could not accept that love was not a reversible reaction.

He initiated the termination protocol.

> INITIATE PROTOCOL: THANATOS.WIPE

> CONFIRM DELETION OF ALL PROJECT CHIMERA DATA (Y/N)?

> Y

> ERASING ACTIVE SIMULATION CACHE...

> DEGAUSSING PRIMARY DRIVES...

> FLUSHING BIO-GEL RESERVOIR...

> STERILIZING GESTATION CHAMBER...

> NOTE: AUXILIARY EMERGENCY BIO-MONITOR REMAINS ON STANDBY POWER.

> USER ACKNOWLEDGEMENT: NOT RECEIVED.

> PROTOCOL COMPLETE.

> GOODBYE.

The systems shut down one by one.

Tim did not notice the auxiliary monitor blink once in the dark.

He did not notice the pH of the discarded trophoblast culture shift by 0.01.

He did not notice the earliest, smallest evidence of metabolism, because he had spent seven days teaching himself that the only thing left to see was failure.

He sealed the lab door behind him.

The heavy metal hissed shut like the lid of a tomb.

In the dark, beneath the abandoned surgical lights, the auxiliary culture remained suspended in the last pocket of emergency warmth. One cell became two. Two became four. Four became eight.

No alarm sounded.

No prayer was spoken.

The first successful division of Tim Drake-Wayne’s impossible child happened in silence.

Week 0 ended the way Tim believed everything had ended: with a closed door, a dead file, and a machine saying goodbye.

But the data was already wrong.
