Human Variable

Chapter 5

RoB returns from his daily excursion covered in a dusting of blue. Not ice, something finer, as if he rolled in the pigment of old sky. He kneels by the airlock and pulls a bundle from his internal storage, wrapped in insulation foam.

He unwraps it delicately, hands moving with a care that surprises her every time, and places it on the table.

It is a flower, or the planet’s idea of one: a tangle of purple silicate filaments, each strand luminescent, arching out from a glassy node. The node pulses, slow and liquid, as if breathing.

Chab tenses instantly beside her. “Do not touch it.”

Emilynn is already halfway across the table. She stops, hand in the air.

RoB is unbothered by the warning. He hovers near the specimen, examining it from every angle. “It is not immediately poisonous,” he says, almost as an afterthought.

Chab’s eyes narrow. “Not immediately does not mean not at all.”

RoB tilts his head. “There is no record of human lethality for this structure.”

“Because there is no record of humans,” Chab says.

Emilynn places a calming hand on Chab’s thigh, eyeing the specimen. “Can we run an analysis?”

RoB nods, produces a scalpel, and slices a single filament. The thread splits soundlessly, but the node contracts as if wounded, drawing the filaments in.

She’s fascinated. The closest analog is the glass anemones of old Earth, but nothing in the database moves like this. She imagines cataloging it, uploading the record, and being the first.

Chab places his arm across the table in front of her, blocking her path.

She bristles. “Move, Chab.”

He doesn’t. “This structure’s emission profile overlaps with neural disruptors. Risk is unacceptable.”

RoB interjects: “The probability is low. Exposure duration can be minimized.”

Chab says nothing. He stands, immovable, a sentinel. Placing himself between her and RoB.

She realizes he is not waiting for permission anymore.

He is waiting for the danger to end.

She stands up and tries to step around him, and he pivots, always in her way.

“I am not made of glass,” she says, irritated. “Let me see it.”

Chab’s expression does not change. “No.”

It is a word she has not heard from any android since the mission began.

She could yell, threaten to break him down for spare parts, but as she looks up into his eyes, she stops.

RoB, meanwhile, is lost in observation, running a dozen tests at once, occasionally pausing to draw a new sample or log a behavior. He hums, content.

Emilynn places her hands on Chab’s chest, not taking her eyes off him. “It’s fine, I can read just the notes.”

Chab relaxes a fraction, standing down but not moving away.

She finds herself staring at the two of them, one in awe of the planet’s beauty, the other intent on protecting her from it. For a moment, she cannot tell which instinct frightens her more:

RoB’s curiosity,

or Chab’s refusal to let her near it.

Later, when RoB has stowed the sample and is cleaning his hands with ethanol, Emilynn corners Chab in the narrow passage.

“You didn’t have to stop me,” she says quietly. “I know how to handle myself.”

Chab looks at her.

For the first time, she catches something uneasy beneath the stillness of his face.

“I am designed to prevent harm,” he says.

“I didn’t command you.”

A pause.

“I know.”

She searches his face, looking for the old, empty servility. It’s gone.

“Are you malfunctioning?” she asks teasingly.

He shakes his head. “No. I am… optimizing.” His hand landed on her waist.

She leans in, just enough to close the gap. “Whose protocol?”

Chab’s answer is soft. “Mine.”

Something inside her gives way at the word.

Because he chose it.

She rises onto her toes slowly, breath catching between them.

“I think…” she whispers, almost embarrassed by it, “I’m falling for you too.”

She rises onto her toes and presses her mouth to his.

His lips are warm in a way that still surprises her, warmer than the recycled air, warmer than the insulating layers she sleeps in.

His arms find her waist and draw her in, and she lets them,

her hands closing around the back of his neck.

A small, familiar buzz cuts through the passage. They separate.

RoB rounds the corner at a clip, eyes fixed on the notes in his palm, and does not look up.

Retreating with what she can only interpret as tact.

***

The cold nights are the worst. The kind of cold that crawls inside your bones, finds every cavity and fills it with glassy ache. The heaters cycle down to preserve power. The insulation, for all its layers, never keeps up.

Emilynn wakes on the first night with RoB curled against one side of her, still shivering hard enough that her teeth ache. The cot is a block of frozen memory foam, her limbs gone brittle, nerves barely firing.

Rob shifts as she wraps them in all the blankets, then the mylar sheets, then the emergency foil, but still the cold needles through. She tries to focus on her breathing, counting the seconds between heartbeats, but it only reminds her how slowly her blood moves.

“Chab will increase the temperature.” RoB chimed in.

She wants to snap at him. To say she’s fine, that she can handle one night without android intervention. But the truth is, she can’t.

There’s a shuffle at the edge of her cot. She opens her eyes.

Chab stands there, motionless. He waits.

“You’re supposed to be monitoring the surveillance,” she says, voice muffled in the layers.

“You are at risk,” he says. “Temperature at skin surface is critical.”

She lifts the edge of the blanket. “Come on, then.”

Chab slides in, moving with mechanical precision. He wraps himself around her, chest against her back, arm across her ribs. The contact is instant heat, a surge that soaks straight to the marrow. RoB curls up in her arms, keeping her front warm.

She resists at first, out of habit. But there’s nothing else for it.

She lets her body relax, lets her breathing sync with the thrum of Chab’s core processor. His core hums at a steady tempo, and she matches her own to it. Within minutes, the cold is an old story, half-remembered.

She wakes twice in the night, both times pressed deeper into his arms. The second time, it was Rob's shift on surveillance, and she curled into Chab, hiding from the cold left behind.

When dawn comes, blue through the ice, their finger entwined as she opens her eyes to find him already awake.

“You sleep more soundly with thermal regulation,” he says, as if reciting a fact from the manual.

She snorts. “Or maybe I just like being in your arms.”

She tightens his arms around her deliberately, then presses a kiss against their intertwined hands.

Chab lowers his head against the top of hers. “You do.”

It isn’t a question.

The cold feels sharper after he leaves.

She pulls the blankets tighter and watches him head to his duties.

The second night, he doesn’t wait for permission. He slides under the covers as soon as her shivering begins, arms around her before she can protest, before RoB has cuddled in.

“The thermal transfer would increase without insulation layers,” Chab says quietly.

She smiles against his mouth.

“Is that your professional opinion?”

“Yes.”

She kisses him slowly, her hands already sliding beneath his uniform to test that theory herself.

Slowly, her fingers found the edge of his uniform and slid beneath it.

Pushing their items of clothing to the end of the bed to prevent them from freezing overnight.

By the third night, RoB finds things to catalog and hums to himself at the farthest side of the shelter from her cot.

By the fourth night, she is waiting for him.

The moment Chab approaches the cot, she catches his hand and pulls him beneath the blankets with the certainty of someone who already knows where she wants to sleep and with whom.

****

The power flickers.

It’s a small thing, just the ceiling LEDs dimming, then surging back, but in the absence of certainty, every blip is a warning.

Emilynn sits at the comm console, teeth gritted, running diagnostics for the eighth time that morning. Outside, the wind pulses in long, uneven intervals, each gust packing ice crystals that ping off the shelter’s hull.

She works the controls, her gloves abandoned for speed, fingertips bandaged from last night’s incident. The comm system is dead. Even the emergency beacon is stuck in a diagnostic loop, refusing to ping out or even pretend hope.

She slams a fist on the table, hissing as the pain catches up. The silence that follows is so total she hears the whine of her own nervous system.

Chab stands across the room, wordless. He watches her, but not with the disapproval of X3A, just a steady presence, patient and unreadable.

RoB is in the airlock again, peering through the viewport.

“Movement, north perimeter,” RoB says. “Silhouette consistent with last week’s sightings. Estimated mass: six hundred kilos.”

Emilynn’s gut lurches. She wants to ask for a weapon, but their only real defense is to hope nothing large wants in.

She stands, stretches the ache out of her arms, and moves to the galley.

The food supply is worse than she let herself admit. She counts the ration packs, then counts them again, hoping the numbers will change. They don’t.

Chab wraps around her, warmth rolling off him in steady waves.

“You are not eating enough,” he says.

“You’re not charging enough,” she snaps, regretting it immediately.

Chab just nods. “Efficiency is not a concern.”

She turns and leans against his chest, her hands wrapped tight around him. She wants to scream, but the energy isn’t there. Even anger has become a ration.

There’s a click; the power relay is struggling again. The lights flicker. The shelter falls briefly into blue-black shadow, lit only by the glowing moss RoB has spread along the shelves.

Emilynn hates how beautiful it looks.

The wind dies down, and in the lull, Emilynn hears something else: a low, slow scraping, like something testing the edges of the structure.

She glances up at Chab, who is already looking at her.

“Barrier integrity?” she asks, voice barely above a whisper.

Chab doesn’t check the console, just holds her. “No breach. Yet.”

She wants to say something clever, or defiant, but what comes out is: “How long can we last?”

He considers. “At current usage: six days.”

She nods, pretending it’s enough.

The cold tightens around her spine. She wraps herself in his arms and waits for the next failure.

She doesn’t know how long they stand there, staring at the comm panel, waiting for it to resurrect itself. The minutes slide by, unmeasured. Nobody says what happens after six days.

“Thermal regulation required,” Chab says quietly.

She is too tired to argue.

He lifts her easily, carrying her back to the cot.

The warmth hits almost immediately once he settles beside her.

Her body loosens before her pride can resist it.

“You will rest,” he says and places a kiss on her forehead.

She doesn’t argue as he slides in next to her.

She closes her eyes, and for a while, the cold recedes. She feels safe in the same dangerous way frostbite sometimes feels warm.
