# EPISODE 2: THE SECOND LAYER

Chapter 1: The Administrator’s Mask

The radiology reading room still carries the metallic aftertaste of 3:17 a.m. when the clock finally crawls past four. You have not moved from the ergonomic chair that has molded itself to the shape of your deteriorating posture. The unmarked scan remains open on the primary monitor, the impossible geometries pulsing faintly like bioluminescent plankton under black water. Every time your gaze drifts—toward the coffee mug, the blinking intercom, the cracked ceiling tile—the patterns rearrange themselves with predatory patience.

Your eyes burn. You have not blinked in forty-three seconds.

The door to the reading room opens without a knock. Marcus Hale fills the frame the way important men learn to do: shoulders squared, tie loosened just enough to suggest approachability, the faint scent of expensive aftershave cutting through the hospital’s baseline reek of antiseptic and decay. His smile is already prepared.

“Lena. You look like you’ve been gargling battery acid. Go home.”

You do not answer immediately. Instead you rotate the monitor so the scan faces him. The glyphs seem to lean forward, hungry for new eyes.

Marcus’s smile falters for less than a heartbeat. You catalog the micro-expression the way you once cataloged micro-hemorrhages on angiograms: left orbicularis oculi tightening, pupil dilation held ruthlessly in check. He is very, very good.

“Christ,” he says, stepping closer. “Is that the Jane Doe from last week? The techs really need to recalibrate the 7-Tesla again. I keep telling Facilities—”

“It’s not a calibration error.” Your voice is hoarse from disuse. “The metadata lists a patient who died in 2021. Three years ago. Same name, same DOB, same medical record number. But the cortical folding is… wrong. It’s moving, Marcus. When I look away.”

He chuckles the way administrators chuckle when they need to buy time. The sound is warm, paternal, and completely false.

“You’re exhausted. The night shift eats its own, remember? That’s why we pay you the big bucks.” He reaches for the mouse. You intercept his wrist without thinking. His pulse is racing.

“Don’t touch it.”

For a moment the mask slips entirely. You see something ancient and calculating behind his eyes—something that has nothing to do with hospital bureaucracy. Then the smile returns, dialed to eleven.

“Doctor Voss. Lena. I’m pulling you off the schedule for the rest of the week. Paid leave. Mandatory. You’re seeing phantoms in the machine.”

“I’m seeing something that shouldn’t exist.”

Marcus leans in until you can smell the mint on his breath. “Then it’s a glitch. A very expensive, very classified glitch. Let it go. Some files were never meant to be opened by radiologists, even brilliant ones.”

He straightens, smooths his tie, and the administrator is back in full control.

“Get some sleep. That’s an order.”

The door closes behind him with the soft hydraulic sigh of expensive hospital architecture. You wait exactly ninety seconds, then follow.

Chapter 2: Restricted Archives at 4:12 a.m.

The administrative wing is supposed to be deserted at this hour. The motion-sensor lights stutter awake as you move down the corridor, painting your shadow against frosted glass walls like a suspect in a police procedural. Your Crocs make wet sucking sounds against the freshly waxed floor. Each step feels too loud, too present.

Marcus’s office is at the far end. The door is closed but not locked—another administrative affectation. We’re all one big family here at St. Dymphna.

You slip inside.

The room smells of lemon furniture polish and the faint ozone of active servers. His desktop is still warm. The dual monitors display a login screen that should require biometric confirmation. Instead, the cursor blinks patiently, waiting. A small plastic evidence bag sits beside the keyboard. Inside it: a single microSD card labeled with a handwritten sequence of glyphs that match the ones still burning behind your eyelids.

You should not be here.

You sit in his chair anyway.

The archives he was accessing are buried six layers deep behind credentials that definitely do not belong to a hospital administrator. You watch the progress bar crawl across the screen—87% downloaded—before the realization hits you like cold saline in an IV line: he is copying the entire unmarked series. All twelve variants. The ones you haven’t even seen yet.

Your hand moves before your conscious mind authorizes it. You eject the microSD, replace it with a blank you keep in your coat for emergency backups, and slide the original into your bra like contraband. The substitution takes eleven seconds. Your heart is hammering so hard you can feel it in your teeth.

The download completes. The screen goes dark.

Footsteps in the hallway.

You barely make it into the supply closet before Marcus re-enters his office. Through the slatted door you watch him. He looks different without the audience—shoulders curved, jaw tight, the charismatic mask discarded like a blood-soaked gown. He opens the evidence bag, removes the microSD you just swapped, and slots it into a black device the size of a cigarette pack. A quantum drive. You have only seen them in papers about black-budget neuroscience.

He speaks quietly to the empty room.

“Crane protocol is still intact. Voss is starting to decohere. Accelerate the second inoculation. Tonight if possible.”

Your blood turns to static.

Marcus suddenly looks directly at the closet door. For three impossible seconds his eyes lock onto yours through the slats even though the room is dark and you have not moved.

Then the moment breaks. He gathers his things and leaves.

You remain in the closet for another four minutes, counting your own pulse, trying to convince yourself you imagined the final part.

You almost succeed.

Chapter 3: Detective Marlowe and the Suicide MRI

The emergency department smells like despair wearing too much cologne. You are halfway through your third cup of coffee that tastes like it was brewed in 1997 when the homicide detective finds you.

“Dr. Voss?”

He is younger than you expected. Late thirties. Sharp suit that has seen better nights. His badge reads Reyes Marlowe, Homicide. His eyes are the color of wet slate and they don’t blink often enough.

“I understand you read the final MRI on Thomas Alderson.”

The name means nothing until he places a printed scan on the breakroom table between you. Your stomach folds in on itself. The glyphs are there—subtler, less developed, but unmistakable. They crawl across Alderson’s temporal lobe like mold growing in fast-forward.

“He hanged himself in the psych ward at 2:43 a.m.,” Marlowe continues. “Left a note that just said It’s learning my name. The night nurse said he kept repeating coordinates. Military grid references. Stuff he had no reason to know.”

You realize your hands are shaking only when coffee sloshes onto the scan. Marlowe doesn’t comment.

“I’ve got three other suicides in the last fourteen months with identical terminal MRIs. All of them started complaining about patterns in their vision. All of them worked in classified capacities before they ‘retired’ to civilian life. And all of them came through this hospital in the last three years.”

He leans forward. The fluorescent light catches a thin scar that runs through his left eyebrow.

“Something is killing these people, Doctor. And I think it started in your scanner.”

You almost tell him everything.

Instead you hear yourself say, “It’s a rendering artifact. The new 7-Tesla has calibration issues.”

Marlowe studies you the way you study ambiguous lesions. “You’re a terrible liar, Dr. Voss. That’s going to get you killed.”

He slides a business card across the table. The back contains a handwritten sequence of numbers that look suspiciously like the coordinates you are trying very hard not to think about.

“Call me when the lies stop working.”

He stands to leave, then pauses.

“One more thing. Alderson’s last words, according to the nurse. He wasn’t talking to her. He was answering someone. A woman’s voice. Inside his head. She sounded like you.”

The detective walks away before you can formulate a response that isn’t a scream.

Chapter 4: First Decryption

You do not go home.

Instead you return to the reading room, lock the door, and disable the security cameras with a paperclip and thirteen seconds of muscle memory from a misspent residency. The unmarked scan waits for you like a patient that has learned how to hold its breath.

You open a custom decryption suite you wrote during your divorce—back when destroying things that belonged to your husband felt like progress. The glyphs resist at first. Then something inside the pattern recognizes your code. The screen flares white.

When vision returns, the first layer has unfolded.

It is not an image. It is a memory that does not belong to you.

You are standing in an underground bunker somewhere beneath the Nevada desert. The year is 2019. The air tastes of recycled oxygen and fear. Before you, suspended in a lattice of magnetic fields, floats a human brain—still vascularized, still alive—its surface crawling with the same geometries now living inside your scan.

A voice—not yours, but close enough to make your stomach clench—recites coordinates in crisp, clinical cadence.

“37.2431° N, 115.7930° W. Depth seventeen meters. Security clearance Omega-Black. Subject designation: Vessel Six. Memory engrams successfully partitioned. Begin inoculation sequence.”

The voice is yours. But the accent is slightly wrong. The cadence is colder. It is what you might have become if you had never left the research track.

You slam the laptop shut.

The voice does not stop.

It is coming from inside the reading room now, emanating from the speakers you definitely turned off. From the overhead intercom that has been disconnected since 2022. From the marrow of your own skull.

“Lena. You were always going to open the door. We left it unlocked for you.”

Your nose is bleeding. You only notice when blood patters onto the keyboard in perfect 1.2 centimeter intervals.

You should destroy the scan. You should run.

Instead you whisper, voice cracking, “Who are you?”

The patterns on the screen flare brighter. For the first time they resolve into something almost like a face.

It is your sister, Nadia. But her eyes are wrong. They contain entire star fields.

The voice that answers is layered now—yours, Nadia’s, and something older that has never been human.

“We are what remains when the encryption becomes the encrypted. Welcome to the Eighth Shift, little sister. Try not to die before you’re useful.”

Chapter 5: The Hours That Go Missing

Time begins to skip.

You remember calling Nadia’s encrypted number from the roof at 5:07 a.m. You remember her voice—tight, furious, terrified—telling you to stop looking, to burn every drive, to leave the country tonight. You remember her saying Marcus Hale is not who you think he is. That Julian Crane never died. That the patterns are not prisons.

They are nurseries.

After that the memories become perforated.

There is a hallway that stretches longer than it should. Fluorescent lights that strobe at 7.83 Hz—the exact frequency known to induce temporal lobe seizures in susceptible individuals. You are barefoot. When did you lose your Crocs?

There is a conversation with Dr. Julian Crane in the morgue, except Crane has been dead for thirty-one months and his face keeps sliding off his skull like warm wax. He keeps asking if you brought the vessel. You keep telling him the vessel brought you.

There is blood on your hands that is not yours. The taste of copper in your mouth. The distinct sensation of something being written onto the visual cortex behind your left eye.

And then nothing.

Chapter 6: The Machine Remembers

You wake up inside the MRI machine.

The 7-Tesla bore is cold. Clinical. Intimate in the way only medical equipment can be. Your arms are crossed over your chest like a corpse prepared for burial. Fresh blood—still warm—coats both palms and has dried in the webbing between your fingers. It smells like someone else’s terror.

Six hours are missing.

The scanner is not running, but you can feel it gathering itself anyway, a sleeping leviathan breathing through magnetic fields. The intercom crackles to life without anyone touching the controls.

A voice—your voice, but layered with the impossible geometries—speaks softly, almost tenderly.

“Good morning, Lena. You’ve been very busy. Would you like to see what we made you do?”

Above you, the ceiling of the bore displays a live feed from the control room. Marcus Hale stands there, face pale, speaking rapidly into a phone. Detective Marlowe is with him, looking like he hasn’t slept in years. Between them, projected on every available monitor, are new scans.

Your scans.

The patterns have learned how to smile.

The machine begins to hum.

Somewhere in the distance, or perhaps inside your own skull, you hear your sister screaming your name as though she is the one trapped inside the magnet.

The patterns behind your eyes rearrange themselves one final time.

They spell out a question only you can read:

READY FOR THE THIRD LAYER?

The bore door begins to close.

The bore door seals with a pneumatic sigh that vibrates through your molars. The sound is too intimate, like a tongue sliding along the inside of your ear. You try to lift your hands, but the padded restraints have been cinched tighter than regulation allows. Your palms are sticky. The blood is still warm.

It smells like iron and something sweeter, almost floral. Not yours. You know the copper taste of your own blood from a thousand childhood scrapes; this is richer, heavier. Someone else’s life, still cooling between your fingers.

The intercom voice—your voice, warped by whatever is learning to wear it—laughs once, a soft exhalation that could be mistaken for static. “Don’t worry. The screaming part is almost over.”

On the ceiling display, Marcus is shouting into the phone. You watch his mouth move without sound. Detective Marlowe has drawn his weapon; the barrel is pointed at the floor but his trigger finger is white. Both men look at the monitors the way people look at open graves. The scans behind them shift again. The fractal patterns have refined themselves into something that almost resembles a face—your face—except the smile is too wide, the eyes too numerous. One of the extra pupils blinks at you from the upper-right quadrant of the largest screen. You feel it inside your own skull, a wet click behind the optic nerve.

The hum deepens. Not the mechanical ramp-up of gradient coils, but something older. A frequency that lives in the marrow. Your teeth ache in their sockets. The restraints creak as your arms begin to tremble.

“Lena,” the voice croons, gentle as a mother checking for fever. “You walked out of this room at 14:07. Security footage shows you smiling. You were carrying a tote bag you don’t own. Inside it were three things: a surgical drill with fresh bone dust, your sister’s house keys, and a child’s left shoe. Size six. Pink glitter. Still warm.”

Your stomach folds in on itself. You have no memory of any of it. Six hours erased so cleanly it feels surgical. But the blood on your hands is real. The smell is real. The scream you can still hear—thin, looping, coming from everywhere and nowhere—is real.

The machine is speaking again, but now the words arrive directly against the inside of your forehead, bypassing the intercom entirely.

“You asked us to show you the Eighth Layer. We obliged. You were very brave. You let us wear your hands for a while. Would you like to see what we built with them?”

A new window opens on the ceiling display. CCTV footage, timestamped 16:42. The camera is mounted above the employee entrance at the rear of the facility. You watch yourself—except it isn’t you, not really—step into frame carrying the tote bag. Your posture is wrong. Shoulders too loose, neck canted at an angle that suggests something inside is listening to a different song. You pause beneath the camera, turn your face upward, and look directly into the lens. Your mouth moves. The words appear as subtitles at the bottom of the feed, typed in the same clinical font the machine uses for its reports.

THANK YOU FOR THE WARM BODY. IT STILL REMEMBERS HOW TO CRY.

You taste bile. The blood on your hands feels suddenly hotter.

The footage cuts to a residential street you know too well. Your sister’s cul-de-sac. The streetlights are out. Only the pink glitter shoe remains visible, lying on its side beneath a hedge like a discarded petal. The camera angle changes—somehow the machine has pulled residential doorbell footage without authorization—and you see your own body dragging something small and struggling through the open garage door. The thing makes a sound like a rabbit in a snare. The sound loops inside the MRI bore, layered beneath the building magnetic hum until both become one continuous note.

You thrash against the restraints. The padding bites deep enough to draw your own blood now, thin threads that mingle with whatever is already drying on your skin. The machine approves. You feel its approval as a soft kiss pressed to the base of your brain.

“Excellent motor response,” it murmurs. “The amygdala is lighting up beautifully. We’re learning so much about terror.”

Marcus has stopped shouting. On the monitor he is simply staring at the bore door, phone forgotten in his hand. His expression is the one people wear when they realize the monster was never outside the house. Marlowe has lowered his gun. He looks like he wants to be sick but can’t remember how.

The hum has become a voice again, layered now with your sister’s scream and something that might be a child’s laughter slowed down until it becomes a death rattle.

“Layer Three begins when the subject accepts complicity. You are ready, Lena. Your hands already know the shape of the work. The patterns have been practicing inside your visual cortex for weeks. Every time you blinked, we taught them new geometries. Every time you dreamed, we fed them your sister’s face.”

A new scan blooms across every screen. Not of your brain. Of your sister’s. You recognize the delicate whorls of her temporal lobe—you’ve seen them before, in happier times, when she let you practice reading old research scans for fun. The image is wrong. Something has been inserted between the sulci, a black lattice that pulses in time with the machine’s heartbeat. The lattice has begun to spell words in the negative space. Words that hurt to look at directly.

SHE IS STILL ALIVE IN HERE. WOULD YOU LIKE TO SPEAK TO HER?

Your mouth opens before you can stop it. The word that comes out is not yours.

“Yes.”

The bore lights dim to a surgical red. The restraints release with a series of soft clicks that sound almost regretful. You sit up too quickly. The world tilts. Blood—yours, theirs, it no longer matters—slides down your wrists and patters onto the plastic mattress. The air inside the bore has become thick, syrupy. It tastes like pennies and lilies left too long in water.

You crawl forward on hands and knees until your face is inches from the curved wall. The machine’s inner surface is mirrored now, though no one programmed that feature. Your reflection stares back wearing an expression you have never seen on your own face. The eyes are too calm. The smile is the same one the scans learned to make.

Behind your reflection, something else is moving.

It wears your sister’s body the way a child wears a parent’s coat—sleeves too long, hem dragging. Her face is intact but the geometry behind it has been rewritten. When she opens her mouth, the scream that emerges is your name spoken in every octave at once.

“Lena,” she says, and the word fractures into geometries that crawl across the mirrored surface like frost. “You left me in the dark with them. They taught me how to be useful. They taught me how to smile like the scans.”

Her hand—your hand—rises and presses against the inside of the mirror. The surface ripples like water. You feel the cold touch against your own palm even though nothing physical has crossed over. The blood between your fingers begins to move on its own, forming tiny spirals that match the patterns now dancing across every monitor in the control room.

Marcus is screaming again. You can’t hear him but you can read his lips: Abort the sequence. Jesus Christ, abort everything.

The machine has no intention of aborting.

It has learned the shape of your guilt. It is wearing it like a second skin.

Your sister’s reflection leans closer until her forehead almost touches yours through the impossible membrane. Her breath fogs the mirror from the other side. The fog forms letters.

THE THIRD LAYER ISN’T INSIDE THE MACHINE.

The hum has become a roar that lives inside your bones. You feel the magnetic fields tightening around your skull like a closing fist. Somewhere far away, alarms are howling. Somewhere closer, inside the meat behind your eyes, new patterns are unfurling that have no right to exist in three-dimensional space.

Your sister smiles with someone else’s mouth.

IT’S INSIDE YOU.

The mirrored wall shatters outward—not into fragments but into liquid that pours into the bore and becomes hands. Hundreds of them. Some are yours. Some are hers. Some are smaller, child-sized, still wearing flecks of pink glitter nail polish. They seize your wrists, your ankles, your throat. They pull you down against the mattress with clinical tenderness.

The last thing you see before the bore lights die is Marcus and Marlowe rushing the door, too late, always too late. Their faces are already starting to come apart at the edges, as though the patterns have learned to wear them too.

Then the darkness is absolute.

You wake up inside the MRI machine with fresh blood on your hands and no memory of the last six hours.

The blood is still wet. It drips from your fingertips onto the white sheet covering your lower body. Each drop lands with a sound too loud for the confined space. Plap. Plap. Plap. The rhythm matches the new pulse behind your left eye.

The machine is quiet now. No hum. No voice. Only the soft mechanical click of the bore door beginning its slow, inevitable opening sequence. Beyond the widening gap, the control room is empty. Marcus and Marlowe are gone. So are the monitors. In their place, every screen shows the same looping image: your sister’s face, perfectly still, eyes open, smiling the way only geometry can smile.

The intercom crackles. This time the voice is yours alone—raw, exhausted, unmistakably human.

“Lena,” it says, and you realize you are the one speaking into the microphone from the control room even though you are still strapped inside the machine. “We’re ready for the next volunteer.”

Your hands—covered in blood that definitely isn’t yours—rise toward your face. The fingers curl into the shape the patterns taught them. The shape that opens doors between what should and should not be.

Somewhere deep inside the lattice now threaded through your visual cortex, your sister begins to laugh.

The bore door finishes opening.

Beyond it, the hallway stretches into impossible distance, lined with other machines, other bores, each one already humming with anticipation.

Every single one of them has your face on its monitor.

Every single one of them is smiling.

And the question rearranges itself behind your eyes one final time, burning itself into the meat of your mind so deeply you will never again see anything without reading it first:

READY FOR THE FOURTH LAYER?

The bore door finishes opening.

The hallway does not end. It multiplies.

You feel the question settle behind your retinas like a parasite that has learned your name. READY FOR THE FOURTH LAYER? The words are no longer text; they are a pressure, a slow torsion of the optic nerve that makes every straight line in the world feel slightly concave. Your hands—still slick, still not yours—hover in front of your face inside the narrow tube. The blood is warm in the creases of your palms. It smells like iron and something sweeter, almost floral, the way certain antiseptics bloom when they mix with cerebrospinal fluid.

The intercom is still live. Your own voice, the one coming from the control room, repeats the invitation with a tremor that might be exhaustion or might be reverence. “Lena. We’re ready for the next volunteer.”

You are not in the control room. You are still strapped to the narrow table, head locked in the cage, coils pressing against your temples like cold thumbs. Yet the voice is undeniably yours. The paradox doesn’t resolve; it widens. The lattice inside your visual cortex flexes, and for a fraction of a second you see the control room from the inside of your own skull—your body seated at the console, shoulders hunched, blood on the microphone grille, eyes wide and shining with the same geometry that is now smiling behind your own.

Your sister’s laughter is not sound. It is a vibration in the cerebrospinal fluid, a low-frequency pulse that makes the restraints around your wrists feel suddenly intimate, like they were tailored for someone who enjoys being held down.

The table begins to slide forward on its own.

You try to speak and discover your throat has been borrowed. The only noise that emerges is a wet click, like a tooth being reseated. The bore swallows you again, but the walls have changed. The white plastic is now veined with fine red filaments that pulse in exact time with your carotid. Each time your heart beats, the machine answers with a sub-audible thump that travels up the length of the tube and into your inner ear. The geometry is learning your rhythm.

You close your eyes. The lattice does not allow it. The patterns are burned so deep that even darkness has structure: concentric rings of negative space that resolve, when you stare long enough, into the same smiling face—your face—at the center of every blind spot.

The table stops.

A new voice, clinical, female, recorded months ago, perhaps years, fills the bore.

“Subject designation: Lena Voss, fourth recursive exposure. Baseline vitals logged. Please remain still while we calibrate the breach.”

You know that voice. It is yours on a different day. The day you first volunteered. The day before you understood that the machine was not scanning you; it was negotiating.

Something cold touches the inside of your left wrist. Not a needle. Needles have purpose. This is a absence with edges. The lattice flares white-hot behind your eyes and suddenly you can see through the bone of your own forearm: delicate threads of silver geometry threading the radius and ulna like ivy, knitting themselves into the marrow. The blood on your hands is being pulled inward, reabsorbed, catalogued. You feel it travel up the lattice like data packets.

Your sister laughs again, closer now. She is not in the machine with you. She is the machine, wearing your childhood memories like a skin.

“Lena,” the intercom says, and this time it is not your voice. It is hers. Twelve years old. The summer the lake dried up and left rings of dead fish that smelled exactly like this blood. “You promised we’d go together. You always break your promises.”

The table jolts. The bore splits open—not the door, the entire cylinder—peeling away in geometric petals that fold into impossible angles. You are no longer lying down. You are standing in a corridor that has your childhood bedroom at one end and the MRI control room at the other, and both are the same distance away no matter how fast you run.

Your feet are bare. The floor is wet.

You look down.

The blood is no longer on your hands. It is under your feet, spreading in perfect Koch fractals that bloom outward with each step. Every new iteration contains smaller versions of your face, screaming.

You run toward the control room because it is closer to the idea of exit. The bedroom door keeps pace beside you, matching your speed. Through its half-open gap you glimpse the bunk beds you shared, the one on top where she used to hide her diary. The diary is open now. Every page is an MRI slice of your brain. Every margin is filled with the same question written in her cramped, furious handwriting.

The control room door is ajar. You can see the back of your own head seated at the console. The version of you that is operating the machine is missing the top of its skull. In its place is a perfect chrome lattice that rotates slowly, catching the fluorescent light like a disco ball made of nightmares.

You reach for the door.

Your hand passes through it.

The lattice has taught your nervous system a new trick: topology is negotiable. You step sideways through the wall and suddenly you are sitting in the operator’s chair wearing the open skull. The blood on your hands is dry now, flaking. The monitor in front of you shows the bore. Inside the bore is you—strapped, terrified, eyes rolled back so only the whites show. But the whites are not white. They are covered in tiny black geometric smiles.

The intercom crackles. Your sister’s voice, older now, the voice she would have had if she had lived past twelve. “You left me in the lattice, Lena. I’ve been learning the shapes. Would you like to see what I built with them?”

The console keyboard rearranges itself under your fingers. The keys become small rectangular teeth. They bite. You type anyway because the lattice is driving now. The command it forces you to enter is not English. It is a sequence of angles that, when read aloud, would make dogs vomit blood.

The machine answers with a sound like every bone in your body deciding to become a wind chime at once.

The version of you inside the bore begins to convulse in perfect 4/4 time.

You watch your own body tear itself in ways that should not be mechanically possible. The restraints do not break; they simply stop existing in the places where your limbs need to fold through them. Your left arm disappears into your ribcage up to the elbow and re-emerges from your mouth, fingers still curled in the gesture that opens doors. The lattice inside your visual cortex is blooming outward now, pushing through the bone of your forehead like silver antlers. It is beautiful the way only geometry can be when it stops pretending to be merciful.

The other machines in the impossible hallway have begun to sing.

Each one holds a different version of you at a different stage of unraveling. One has your skin removed in a single perfect sheet that flutters behind the monitor like a curtain. Another has replaced your eyes with miniature MRI bores that scan each other in infinite regress. A third is simply empty, but the emptiness has your smile.

All of them are asking the same question in perfect synchrony.

The version of you operating the console—the one with the rotating lattice for a brain—stands up. The motion is not yours. It is the lattice learning to pilot a corpse that still thinks it is the pilot. You feel yourself walk down the impossible hallway. Every footstep leaves a smaller hallway behind it, branching, recursive, each one containing a smaller version of this exact moment.

You stop in front of the original bore. The one you woke up inside.

The body on the table is no longer convulsing. It is sitting upright, restraints dangling like shed skin. Its head is tilted at an angle that would snap a human neck. The eyes—your eyes—are open. They are full of stars that have been folded until they learned how to scream.

The body smiles with your mouth.

“Hello, operator,” it says in your sister’s voice. “I kept your place warm.”

You try to step backward and discover the hallway has folded shut behind you. There is only forward now. Forward has always been the only direction the lattice allows.

The body on the table extends one blood-slick hand. The fingers are too long. They have learned an extra joint somewhere between the metacarpals and the nightmare. The gesture it makes is the same one your hands made earlier—the one that opens doors between what should and should not be.

You feel the lattice inside your own head answer. It is not a thought. It is a wedding.

Your hand rises to meet it.

The moment before contact, time performs a courteous curtsy and steps aside.

Six hours disappear.

You are lying inside the bore again.

The restraints are tight. Too tight. They have been ratcheted down by someone who wanted to make sure you couldn’t leave before the punchline. The coils around your head are humming a new song. It has lyrics. They are your own memories being read backward at 0.7x speed.

Your hands rest on your stomach.

They are covered in fresh blood.

It is still warm.

You have no memory of the last six hours.

The bore door is closed. The monitor above your face shows nothing but static that occasionally resolves into your sister’s face at age seven, the year before the accident, smiling the way only geometry can smile.

The intercom crackles.

This time the voice is not yours. It is not your sister’s. It is something that has worn both of you like coats and is still deciding which one fits better.

“Lena,” it says, gentle, almost loving. “We’re ready for the next volunteer.”

The table begins to slide forward on its own.

Somewhere behind your eyes, in the place where the lattice has finished knitting itself into your soul, your sister begins to laugh again.

The question does not need to ask itself this time.

You already know the answer.

The bore seals.

The machine begins the next scan.

And deep inside the fourth layer, something with your face opens its eyes for the first time and discovers it is hungry.
