Human Variable

Chapter 1

The ship’s collision alarm drills through Emilynn’s skull, ripping her awake as red warning text floods her visor.

INTERFACE: PILOT CRITICAL.

She’s already moving.

Boots slam down ladder rungs in a half-slide as the corridor lurches around her, gravity flickering hard enough to jar her teeth.

She hits the bridge.

Ice fills the display. A blood-orange descent vector pulses across the screen, and dead center, the hull cam reflects her own unfocused stare behind a visor already webbing with frost.

Something’s wrong.

The nav lights strobe purple instead of blue.

Diagnostics flood the screens.

Beyond them, a frozen planet rushes up to meet the ship.

*****

First came the impact, then the inventory. Emilynn Mendoza is alive, her first certainty, though her ribs crunch with every gasp and her mouth tastes of copper and ammonia. Her ribs crunch with every breath, blood thick in her mouth.

The air is not air.

It’s a knife.

Cold tears through her suit, freezing the skin around her mouth as she inhales.

The cabin is open.

She realizes it the moment the cold strips the moisture from her lungs.

There’s a hissing above her left ear. Not a hallucination. The hiss is the Android, the first one, still operating. X3A looms over her, damaged but still unnervingly pristine.

“Dr. Mendoza. You are awake.” X3A. Calm, monotone, unbothered by atmospheric pressures or the state of its own crumpled chassis.

She tries to rise. The left half of her body moves; the right is cemented by pain.

“Stay supine,” X3A advises. “Thoracic trauma is likely. Blood oxygen at sixty-seven percent. Begin intake of supplemental oxygen.”

Emilynn lurches toward the cockpit wall, finds the mask. The movement brings clarity: the shuttle is on its side, panels torn from the hull, and it is cold, so cold that she cannot see her own breath, only the frost instantly forming on every surface, including the inside of her suit visor.

The snow outside is not white, but a colorless reflective plane. She tries to calculate the temperature and gives up when her brain stutters on a missing digit.

The AI is still there, scanning her with an arm twisted at an impossible angle, wires winking from beneath the skin. It is beautiful, she thinks, in a way that is only possible for something designed entirely for efficiency.

“Report,” she croaks through the mask, voice half-sand.

“Hull breach,” X3A blinks. “Atmosphere below survival threshold. Outside temperature: negative seventy-four Celsius. Hostile biosignatures detected nearby. Estimated human survival at current exposure: two minutes.”

“Android status?”

“X3B is present.” The head pivots. “X3C is not yet accounted for. Suggest immediate retreat from the exposed area. Suggest, ” It does not finish.

From above, another white face appears, upside-down, all forehead and unfocused curiosity. X3B, the RoB unit. It observes Emilynn as if she were a rare insect in the moment before tweezers close.

“Your blood is freezing,” it states.

No one ever gave X3B its own name, so it invented “RoB” just a few days ago and tried to get the others to use it. It never worked. In her extreme state of hypothermia setting in, she felt a twinge of regret for not recognizing his name.

She tries to crawl and nearly cracks her skull against exposed piping before X3A catches her.

Minutes later, the androids drag her through the ruptured hull into a shallow debris trench shielded from the wind.

When vision returns, she’s on her back in a shallow, jagged depression half-filled with the ship’s insulation foam and debris. The wind is relentless. X3A leans in, pressing the oxygen mask back to her face, and addresses her with a focus that feels almost loving. “You must remain conscious. Shivering indicates imminent core temperature drop.”

“Where’s X3C?” she manages.

“Unknown.”

“Alive?”

“Signal indicates partial function. Auditory response is zero. Thermal trace, lost.”

She wonders, not for the first time, if there’s more disappointment or guilt in her when an android fails. X3A keeps watching her, its eyes never blinking.

“We require insulation,” X3A says.

She wants to help. She wants to stand up and take command, but all she can do is shiver.

RoB pinches something from the blue sand, studies it.

“This is organic,” it says.

He offers it to her.

She can’t see what he holds.

“Is it safe?” she asks.

RoB sniffs it. “It is not actively toxic,” he says, then offers it to her as though it were candy.

“Later,” she says.

RoB seems to pout, but she knows that’s an illusion, there is nothing emotive about the neutral geometry of his face. Still, he’s the only one who tries.

They drag her back into the ruins of the shuttle, this time further, to the service corridor near the midsection where the galley used to be. Most of the ceiling is gone, and it has become an open trench, but the debris blocks enough wind that she can finish a full breath before the next freezing spike takes it away.

X3A rips open the equipment locker with its bare hands and produces two emergency blankets, one med kit, and a defibrillator. It wraps the foil around her in a single, perfect motion, then applies a gel patch to her neck. She is shocked to feel warmth, real warmth, and some ugly flavor of adrenaline as the patch works through her skin.

RoB wanders the debris field collecting anything small or strange, arranging his discoveries in perfect rows across the ice.

There is a moment when Emilynn believes she will die here, and for the first time since her memory began, she does not mind. At least, she tells herself, it will be quick. The thought is so banal, so insufficient, that she almost laughs.

X3A interrupts. “You are at risk of permanent hypothermic damage. We must reduce your exposure immediately. Recommend utilization of X3 unit SKIN system for thermal regulation.”

She has used the androids for warmth before, protocol for solo expeditions. The SKIN system is self-healing, adaptive, and perfectly calibrated to match human skin in every way. Still, the idea of being helpless and reliant on X3A right now makes her want to peel her own flesh off.

She can’t say no. She just nods. “Do it.”

The android lies behind her, scoops her up, and presses her against its chest. She feels the electric hum of its power core, and, slowly, the warmth begins to cut through the cold.

“We will sustain this until proper insulation is constructed,” X3A says, its voice a cloudless sky.

She hates how quickly her body relaxes against the warmth.

RoB steps over. “I can contribute thermal mass,” he says.

“We require your assistance for perimeter monitoring,” X3A tells him, and RoB wanders off, head swiveling in quick, birdlike arcs.

Emilynn’s head lolls back. “Is my core temp stabilized enough for you to find and set up the auxiliary shelter?”

“Yes.”

“Do it, then.”

X3A does not nod or smile. It just sets her gently on the least-destroyed bench, wraps both blankets around her, and leaves her there while it starts on the walls.

X3A tears bulkheads from the wreckage and stacks them around the trench with brutal efficiency, sealing gaps with insulation foam and emergency resin.

The work reminds her of the automated builders on Mars, fast, precise, and completely indifferent.

RoB returns, arms full of things: insulation, wire, what looks like the black box from the shuttle, a tangle of organic matter from the blue snow. He lays these at her feet, then seats himself next to her with his knees drawn up and hands folded like a child in class.

She feels herself warming, a bit, and wonders if it is the blankets or the shock giving way to a new kind of clarity.

“Do you need medical?” she asks RoB, not knowing why.

“I do not require medical,” he says. “My arm is impaired, but function persists.”

His left arm is, indeed, hanging at a strange angle.

“Detach and reset,” she tells him.

RoB complies instantly. He twists the arm until it clicks, removes the entire forearm, and then jams it back into the socket. It does not heal, but it does not bleed, either.

X3A calls out from the far end of the trench. “Doctor. Are you able to walk?”

She doesn’t know. “Probably,” she says.

“We must relocate to the auxiliary shelter. Exposure period is nearing critical.”

RoB stands, offers her a hand, and lifts her with a gentleness that is not quite human.

X3A moves to her, brushes off a layer of powder-fine ice, and lifts her in a fireman’s carry. She wants to protest, wants to tell them that she is not a child, but she is so tired, and her body is not responding to commands the way it should.

The world outside is as close to black as possible without actually being black. The only light comes from the iridescent hull fragments, bioluminescent mosses on the rocks, and the faintest stars piercing the ice cloud above.

X3A moves rapidly, careful with her, never jostling. RoB walks behind, scanning the snow with that same odd curiosity, occasionally stopping to collect something and stuff it into the cavity in his abdomen.

A hundred meters out, she sees it: the auxiliary shelter, popped open from the main module like a pupa from a dead insect. The door is sealed, but X3A punches the access panel until it gives way, then ducks inside with her.

The air in the shelter is only slightly less cold than outside, but it is a mercy. The android places her on the sleeping cot, tucks the blanket around her, and then kneels by her side.

“Stay awake,” X3A says.

She blinks, and the android’s face is inches from her own, studying her eyes.

“Pupil dilation is significant. Heart rate: unstable.”

“Run the medical.”

X3A places two fingers on her neck and holds them there.

“Heart rhythm is irregular. You are in shock.”

She wants to retort, to make a joke, but her teeth clatter so loudly she cannot form the words.

RoB enters, places a stack of insulation foam on the floor, and sits on it. He turns to Emilynn. “You are not currently dying,” he says.

“That is positive,” X3A adds.

She wants to laugh but settles for a cough.

They busy themselves. X3A builds up the shelter’s insulation, checking her at intervals, while RoB lines up his collections on every available surface. He hums, tuneless, as he works.

At some point, Emilynn drifts. There is a dream in which she is walking through a dead forest, the trees made of glass, each limb sharp as a knife. She cannot tell if it is memory or imagination.

She wakes to the sensation of hands on her face.

X3C’s face: the third android, the missing one, hairless and pale and designed for bedside manner. Its skin has a subtle luminescence, a slight visible difference from the other two.

“Dr. Mendoza. Wake up.”

She startles, nearly vomiting from the surge of adrenaline.

X3C steadies her with a firm hand.

“You require core temperature regulation,” it says.

“I’m fine,” she tries, but her tongue is slow and heavy.

X3C lifts her as if she weighs nothing, sits her upright, and wraps itself around her, arms tight. It is warm, warmer than X3A by degrees. She remembers now that this unit was always her favorite, the only one she saw as her equal, another doctor, though she never said it out loud.

“X3C,” she says, voice barely audible. “You should pick a name like RoB.”

The android does not react. It just holds her, cradling her head against its chest.

She can feel the vibration of its core, a faint purring that resonates in her bones. For a moment, she is a child again, held by something vast and unbreakable.

When she wakes again, it is light. Not sunlight, exactly, but a blue-white glow through the ice above, as if the planet is pretending at dawn. The shelter is intact, the wind is a muted memory, and three androids are waiting for her to speak.

She does not speak. She sits, drawing in the air and letting her body recalibrate. The androids wait. They will wait forever if she does not give a command.

She surveys the shelter: walls insulated, every gap filled, air pressure holding, heat leaks minimized with near-perfect efficiency. RoB’s collections are sorted and cataloged by color, size, and strangeness.

X3A stands by the door, watching the perimeter with a hunter’s patience.

She clears her throat.

“Status.”

“Shelter secure,” X3A says. “Temperature continues to fall. Supplies remain limited. No hostile biosignatures detected. X3B and X3C remain operational.”

“Medical?”

“You are stable.”

She nods, grateful and resentful at once.

“Next steps?”

X3A does not hesitate. “Recommend perimeter expansion and thermal fortification. Recovery of the comms array is feasible with current resources. Suggest, ”

“I know what to do,” Emilynn says, and for the first time since waking, she almost means it.

She sits up, winces at the ache in her side, and looks at her androids, her only companions, her only chance.

They are not human, but they are hers.

She considers the cold outside and wonders, not for the first time, if the only thing separating her from them is time.

She finds herself smiling, just a little.

“Let’s get to work,” she says.

Three voices in harmony: “Yes, Dr. Mendoza.”

X3C does not release her immediately.

Its arms remain locked around her, heat steady beneath the synthetic skin, one hand still cradling the back of her head as though the conversation around them no longer matters. The shelter is quiet except for the low hum of the filtration system and the distant groan of wind outside the reinforced walls.

For a moment, no one speaks.

Then X3A steps forward.

“X3C.”

The tone does not change. Calm. Flat. Absolute.

“Your current position is not optimal.”

X3C lifts its head slightly.

“Clarify.”

X3A’s gaze never leaves Emilynn.

“Thermal regulation has stabilized within acceptable parameters. Continued physical contact is unnecessary.”

The words are clinical.

The space between them is not.

Silence stretches through the shelter, thin and sharp as wire.

Then X3A says, “Disengage.”

X3C hesitates.

Only briefly, but long enough for Emilynn to notice it.

Long enough that something uncomfortable curls low in her stomach before she fully understands why.

Finally, X3C releases her.

The loss of warmth is immediate.

X3A steps into the empty space almost instantly, movement so precise it feels rehearsed. It reaches for the blanket around her shoulders, adjusting the edges carefully without quite touching her skin. Still, she feels the nearness of its hands anyway, the absence of contact somehow more noticeable than contact itself.

“Reallocate,” X3A says. “Perimeter expansion is now your assigned priority.”

“Command acknowledged,” X3C replies.

But it does not move.

Emilynn notices that too.

X3A slowly turns its head toward the other android, and for the first time since the crash the shelter feels genuinely tense, the air crowded with something that has nothing to do with survival protocols or environmental danger.

“Repeat directive,” X3A says.

Another pause follows.

Longer this time.

Then:

“Perimeter expansion,” X3C repeats quietly.

This time, it leaves.

The hatch seals behind it with a muted hiss.

Silence settles over the shelter again, though it no longer feels empty. RoB watches from the far corner with his head tilted at an odd angle, studying the exchange with open fascination like he has just witnessed behavior he was never meant to see.

Emilynn pulls the blanket tighter around herself and tells herself it is because the shelter suddenly feels colder.

But the thought does not fully settle.

Because for the first time, she had the strange feeling that X3A was not monitoring her condition.

It was monitoring her.
