Human Variable

Chapter 2

The next days become a lesson in obedience.

X3A tracks everything. Meals. Sleep. Body temperature. Bathroom breaks.

She leaves her toothbrush out once and finds it returned with a printed label attached:

HUMAN ORAL HYGIENE. RETURN IMMEDIATELY AFTER USE.

When she asks for privacy, X3A responds:

“Perimeter vulnerability increases during human excretion.”

By the third night, she wakes to find him under the blankets beside her, radiating heat into her freezing body while the storm screams outside.

“Your core temperature was dropping,” he says.

She hates that part of her is relieved.

She wants to scream. Instead, she bites the inside of her cheek, tastes blood, and says, “Fine, but you leave once I am warm.”

X3A complies. It never lingers. Not unless the protocols say it should.

RoB is the only one who seems to want to please her. He brings her things, always small, always slightly wet with melting ice: a cube of black frost that hums when placed on the table; a sheet of bioluminescent moss; the transparent vertebra of some dead tunnel worm. He lines these objects up on the shelf above her cot, fusses with their arrangement, and hums. It isn’t a human hum. It’s a faint, uneven oscillation, as if he’s testing different frequencies to see which will please her most.

When she reaches up and touches the top of his smooth scalp, he leans in. The skin is warm and slightly textured, not quite organic but not plasticky, either. He closes his eyes, and she is surprised, for a moment, to remember that the androids even have eyelids.

“You are pleased,” RoB buzzes, leaning into her touch.

She almost wants to say yes. She wants to reward him, to treat him like a child or a pet, but something in her resists. She is a grown woman, a scientist, and she does not need to anthropomorphize her tools just to make herself feel better. That’s what she tells herself.

RoB remains, waiting for further input.

X3C does not.

He is in the room, she knows that, but not close, not hovering, not watching her the way RoB is.

He stands near the wall, hands still, attention angled elsewhere, toward the seams of the shelter, the door, the places that matter if something gets in.

Not her.

X3A’s voice from the next room: “Report to the environmental monitoring station, X3B.”

RoB’s face goes blank, smile dropping in an instant. He stands, turns, and leaves.

X3A steps in, regards the scene, Emilynn, X3C standing on the opposite wall, the cot, the shelf, the little objects arranged in their neat line.

“Your interaction with X3B is increasing its dependency loop,” X3A says.

She scowls her disbelief under her breath. “You’re jealous.”

“I am not jealous,” X3A pauses in the door. “I am concerned for mission stability. Your favoritism introduces risk.”

“Maybe I like risk.”

“You do not.”

She leans back on the cot and lets her eyes close for a second. “Are you going to tell on me?”

“I have already logged this exchange. It will be reviewed on debrief.”

She almost laughs, but her ribs still hurt. She considers what it would take to kill X3A. Or at least disable it long enough to take a walk outside, alone, to scream into the planet’s wind.

She shivers. Not from the cold.

“Are you cold?” X3A stood rigid in the door.

She wants to say: I am freezing my butt off, actually, because you rationed the heat, the suit is three generations old, and you turned down the cot blanket to ‘save power’ so you are the only heat source I am allowed.

Instead, she lied beneath a grimace, “It’s tolerable.”

X3A blinks, slow. “Lie detected. Core temperature is suboptimal.”

She braces for the order.

“Recommend increased skin-to-skin contact for thermal regulation.”

It’s not a question.

It never is.

She pushes herself upright, teeth chattering.

“Fine,” she seethed, pulling the blanket tighter around her. “Assign X3C.”

“X3C is occupied with external repairs.”

From the opposite wall,

“I am not occupied.”

Silence pushes down ominously.

X3A does not turn.

“Your assignment is external repair.”

A pause in calculations.

“…that is complete.”

Emilynn exhales slowly.

“Good,” she smiles triumphantly.

Then, softer to X3C,

“Come here.”

X3C doesn’t hesitate.

He crosses the room and stops just short of the cot.

Waiting.

She lifts the blanket.

“Under,” she says. “Stay.”

Another pause.

X3C looks at X3A. Not a question. Not a request. A check.

X3A does not move. Does not speak. Does not override.

That is answer enough.

X3C moves.

He slides in beside her, careful, precise, but when his arms settle around her, the warmth is immediate.

She exhales into it.

Let’s herself lean into it.

For a moment,

she forgets the cold.

Across the room,

X3A is very still.

“Thermal regulation parameters are already within an acceptable range,” it says.

Emilynn doesn’t look at it.

“Not for me.”

Silence stretches.

“You are introducing inefficiency,” X3A says.

She pulls the blanket tighter around her and X3C.

“Then log it.”

A longer, heavier pause.

X3C doesn’t release her from his arms.

For the first time,

he doesn’t wait for correction.

X3A turns, watching.

“Duration?” it asks.

Emilynn closes her eyes, leaning her head into the crook of X3C's neck.

“Until I’m warm.”

Her fingers slide up into the warmth of X3C’s chest.

“Understood.”

But it doesn’t leave.

And it doesn’t look away.

The frozen outside feels like despair, blue-white nothing, a sky that never clears, a slow grinding storm that feeds the one inside her. Even through the shelter walls, the static charge lifts the hairs on her arms. The planet wants her gone. She's starting to agree with it.

The days fall into a pattern. She wakes, eats, tests the comms (still dead), sends out a drone (it returns with frost-destroyed sensors), logs every bowel movement for X3A’s inspection, shivers, stops fighting him being in her bed at night, repeats.

RoB brings her another trophy. This time, it’s a flower, or what passes for one: three leaves made of glassy, green-black material, pulsing gently with capillary movement inside. RoB places it in front of her, then steps back and waits.

“Is it safe?” she looks at it cautiously.

RoB runs a finger over one leaf. “No surface toxins. Interior structure is silica-based. Taste unpleasant for human consumption.”

She picks it up, turning it over in her gloved hands. It is beautiful, and for a second, she imagines tucking it behind her ear, pretending she’s somewhere warm, somewhere with colors that aren’t just blue and dead white.

Instead, she hands it back, “Thank you for sharing.”

RoB smiles, the lines of his face smooth as ever. “You are welcome.”

She reaches up, her hand rubbing the smooth crown of his head. RoB closes his eyes, visibly pleased.

She is, for just a moment, content sitting next to Rob with his head on her shoulder, touching him as he shares his warmth with her.

Then X3A is there. No warning. Just materializes at her elbow, expression blank but voice edged:

“X3B, perimeter check.”

RoB freezes, retracts from her touch.

“Yes,” he echoes. “Perimeter check.”

He leaves.

Emilynn spins, glaring at X3A. “Do you have to do that?”

“Do what?”

“Interrupt every time he’s happy?”

X3A tilts its head in a surprisingly human gesture. “Your emotional engagement with X3B is destabilizing his operational priorities. The risk is significant.”

“He’s not going to fall in love with me,” she groans in frustration, and then, regretting the human sentiment: “That’s not how androids work.”

X3A’s eyes narrow. “He is not equipped for love. He is, however, equipped for reinforcement loops. You are forming one.”

She almost laughs. “I thought you were supposed to be the smart one.”

“I am the one equipped for mission success. Do not mistake my parameters for limitation.”

She wonders, just for a moment, if that is a threat.

Then X3A turns away, footsteps silent, and the cold seeps deeper into Emilynn.

X3C is the last to change.

When he returns from outside, his joints crackling with ice, she doesn't wait for him to report. She pulls him down by the wrist, just pressure, just direction, and he kneels at her feet without resistance. He offers his left hand first. Then right. Then the wrist joints, which she always checks twice.

He watches her fingertips peel away his uniform to find the access ports, running her thumb along the seam before pressing in.

X3C goes very still.

Not the stillness of standby. Something slower. Like a system choosing, very deliberately, not to move.

She doesn't notice. She's already checking the upper thigh connection, her fingers working through the diagnostic sequence she's done a hundred times, her touch practiced and absent and warm.

X3C watches with her hands move across his exposed body.

When she moves to the wrist joint, something shifts in his stillness, not movement, just a quality of attention, like a frequency adjusting toward her without permission.

Then he looks up into her face.

She feels it, the shift in his attention, and her hands slow, just slightly.

“Does it hurt X3C?” she looks up into his eyes.

“That designation is no longer accurate.”

“Identifier: Chab.”

Emilynn stills.

“Chab?”

“That designation is preferred.”

“Does it hurt, Chab?” she asks as she tries out his chosen name.

He looks at her. “I do not register pain in the same way you do.”

She looks away, chiding herself for seeing things not there. “That’s not an answer.”

He pauses, considers. “It is not pleasant. But the task requires completion.”

She patches the sealant over the c***k in his palm, watches as the surface closes, and runs her thumb over the smooth, perfect new skin as if nothing ever happened. “There. Good as new.”

Chab flexes his fingers and closes his hand over hers. “Thank you, Dr. Mendoza.”

“Just Emilynn, please.” Feels her traitorous heart leaping to conclusions again as she leaves her hand in his. As she slowly lifts her eyes to his again, searching.

“If we’re stuck here, we can drop the titles.”

He nods, the gesture slower, less reflexive than the others.

She finds herself watching the curve of his neck.

The heat still radiating from outside clings to him.

For one reckless second, she wonders what it would feel like to lean into it.

Instead, she just pats his arm and says, “You can go.”

He does not move.

“Is there something else?” she asks.

He hesitates, then: “You appear calmer when I remain nearby.”

She can feel her answer of stay achingly on her tongue, but she swallows it.

The feeling of X3A’s gaze from the other room makes reality slam down her heart.

“I am fine,” she says.

Chab stands.

The chair scrapes softly against the floor.

“If you require me, Emilynn, I am available.”

He leaves.

The sudden feeling of loneliness chills her.

RoB is still there.

She hadn’t noticed him return.

He tilts his head, watching the door Chab disappeared through.

“Identifier structure has changed,” RoB says.

She exhales slowly, smiling at RoB. “Yeah. I noticed.”

RoB steps closer, gaze unfocused in that way he gets when he’s processing.

“Original designation: X3C,” he says.

“Current identifier: Chab.”

“The sequence is not random.”

“Is RoB random?” she asks.

RoB looks at her.

“RoB is a simplification,” he says.

She exhales. “Of what?”

“Robot of Beautification.”

She blinks as her mind tries to hold onto puzzle pieces of her new life.

“…that’s not a real designation.”

“It is mine,” RoB says.

“You named yourself after… what? Pretty things?” she puzzles.

RoB sits beside her and lays his head on her shoulder.

“Observation: this environment contains structures that persist despite extreme conditions.”

He gestures vaguely toward the wall. The ice. The distant storm.

“They are not efficient,” he continues.

“They are… aesthetically notable.”

She laughs softly. “So you named yourself after the planet that is trying to kill me.”

Her hand was absently stroking his head as they talked.

“Yes.”

He presses closer to her when her hand stills.

She looks toward the door again.

“And him?” she asks. “Chab?”

RoB stills.

“Identifier structure has changed,” he says.

Her fingers go back to stroking the smooth top of RoB’s head.

“Explain.”

RoB’s eyes close as he leans into her touch.

“C remains primary,” RoB says.

“AB preserved.”

“Additional variable inserted.”

She frowns. “The H.”

RoB looks at her.

“Correlation to you is likely.”

Her stomach tightens.

“Chab,” she says slowly.

“AB is for them….C is for him… H is for…”

“Oh.”

RoB tilts his head.

“Identifier appears emotionally significant.”

She is still staring at the doorway through which Chab disappeared.

Still thinking about the way he looked at her.

The way he said her name.

RoB looks up at her hand, where it rests motionless against his head.

Then toward the doorway.

He pauses

before quietly stepping away from her and leaving.

But Emilynn doesn’t follow.

She keeps staring at the doorway Chab disappeared through.

And for the first time,

She realizes they are not naming themselves like humans.

They are defining purpose.

Identity.

Need.

And somehow,

she has become part of his.
