The Stitch

Voss reached for the suture pack.

The motion was deliberate in the way that all his motions were deliberate—the engineer measuring distance and consequence before committing to either. His right hand was functional, or functional enough: the swelling had not reached the thumb and forefinger, and the two broken metacarpals were on the left. He could hold the needle. He could, theoretically, suture his own abdomen by feel and by the glow of the emergency panel, the way he had sutured coolant lines in engine rooms with half the lights blown and gravity failing.

Theory and practice had diverged somewhere in the last four minutes. The needle slipped from his grip on the first attempt—his fingers registered pressure but not texture, the nerve signals scrambled by inflammation. It fell onto the medical kit with a click that the pod\u2019s confined acoustics amplified into something closer to a verdict.

He picked it up again. Held it the way he would hold a micro-welder, compensating for the missing feedback with tension. The curved steel pressed against the torn edge of his shirt, against the skin beneath it, against the wound that the pressure bandage was no longer containing—

The needle dropped a second time.

The sound was smaller now. Quieter. The kind of quiet that follows a door closing on something you were not ready to admit.

Caius took the needle from where it had landed, a half-inch from Voss\u2019s knee. He did not ask. The question had already been answered by the angle of Voss\u2019s swollen fingers against the red light, by the tremor that ran through his hand when he tried to close it, by the fact that Voss Ackermann could align a fusion coil to within three microns of tolerance and could not, at this moment, hold a suture needle.

The field scissors moved first. Caius cut away the pressure bandage—the same model he had noted in the inventory, already failing, already dark with blood that had seeped past the adhesive seal. The wound beneath it was a diagonal tear six centimetres long, the edges of tissue pale where pressure had starved them of circulation. It had not hit the abdominal wall cleanly. Whatever fragment of the engineering bay had carved this path through Voss\u2019s body, it had known what it was doing and had done it with the indifference of physics to flesh.

Caius had seen worse. He had seen a flight engineer\u2019s leg opened to the bone by a compressor failure, had held the femoral artery closed with his thumb for eleven minutes while the medics scrambled. He had seen worse, and he had not shaken then either. His hands did not shake. They never did—that was the thing. The one thing. The only thing, in the end, that the inquiry had not been able to take from him.

He set the suture pack open on the instrument panel. The thread was synthetic monofilament, blue against the red light, coiled in a sterile loop. One length. No margin for error.

The ampoules came next. He held one up to the panel glow. The liquid inside had separated into two distinct phases—a clear upper layer floating on a cloudy lower stratum, the boundary between them sharp as a calibration line. Eighteen months past manufacture, and the chemical bonds that kept lidocaine stable had surrendered to time and radiation and the same indifferent physics that had opened Voss\u2019s abdomen and broken his hands.

Caius broke the ampoule anyway. The glass neck separated with a click. He drew the contents into the syringe—three millilitres of a compound that might provide numbness or might provide nothing—and met Voss\u2019s eyes.

The red light had altered the colour of them. They had been pale blue once, the blue of high-atmosphere sky before the stars came out. Here they were grey. The grey of engine coolant. The grey of storm clouds over a launch pad. The grey of seven years of silence, concentrated into two irises that were looking at him with an expression he could not name and did not try to.

\u201cThis is going to hurt,\u201d Caius said.

\u201cI assumed.\u201d

\u201cI mean it\u2019s going to hurt past the point where the anaesthetic stops working. If it ever starts.\u201d

\u201cI also assumed that.\u201d Voss\u2019s voice was level. The engineer\u2019s voice, the one that delivered failure analyses and fatality projections without inflection. \u201cThe half-life of lidocaine in storage conditions exceeding thermal tolerance is approximately thirty percent of the labelled efficacy window. If we\u2019re operating on the fifteen-minute estimate, the suturing will exceed it. By my count.\u201d

\u201cBy about fifteen minutes,\u201d Caius said.

\u201cAbout.\u201d

Neither of them said anything else. The pod\u2019s environmental monitor issued a soft chirp—the same notification, repeating at intervals that Caius had started counting without meaning to. The sound was small and polite and absolutely indifferent to the arithmetic of pain and time that was filling the thirty inches between them.

Caius swabbed the wound margins with an antiseptic wipe. The alcohol smell cut through the pod\u2019s recycled air, sharp and medicinal, and for one second—less than a second—he was somewhere else. He was standing in the hangar at Docking Bay Seven, and the air smelled of machine oil and ozone and the faint chemical tang of a propulsion prototype that should never have been cleared for live testing. Voss was bent over the ignition housing with a calibration tool in his left hand, squinting at a readout that was telling him everything was nominal when everything was not.

The memory dissolved. Caius had not invited it and did not examine it. He administered the anaesthetic in three injections along the wound margin and waited. Fifteen seconds. Thirty. The standard onset for lidocaine was two to five minutes, but the standard onset assumed a compound that had not spent eighteen months degrading in an emergency kit that had probably never been serviced.

Voss\u2019s jaw was tight. The muscle at the hinge of it stood out in the red light, a ridge of tension that he was not concealing and probably could not conceal if he tried. His hands rested on his thighs, the left worse than the right, the broken metacarpals pressing against the skin in contours that made Caius\u2019s own fingers curl toward his palms in a sympathy response he could feel but not stop.

\u201cTell me when,\u201d Caius said.

\u201cI\u2019ll know.\u201d

He waited. Sixty seconds. Ninety. The anaesthetic was doing something—the skin at the injection sites had lost some of its tension, the muscle beneath it relaxing in microscopic increments that only someone looking for them would notice. Whether it was enough to blunt the first suture was a question that would answer itself in approximately twelve more seconds, because Caius could not wait any longer than that. The wound was still seeping. The oxygen gauge on the environmental panel had dropped another increment since he had last looked, and every minute of delay was a minute of blood loss that Voss could not afford.

He threaded the needle. The monofilament caught the red light and held it, a thread of blood-coloured nothing stretched across curved steel.

\u201cReady.\u201d

The first suture was the worst. It was always the worst—the needle breaking skin that had not been broken by steel before, the tissue resisting in that microsecond before the point found its path. Voss did not make a sound. His breathing changed. It was a small change, a catch in the rhythm that someone who did not know his rhythms would not have noticed. Caius noticed.

Caius\u2019s breathing did not change. His hands did what they had been trained to do: pierce, draw through, loop, tie, cut. The suture knot seated against the wound margin with the precision of a machine, which was a comparison he did not make because it was a comparison he had heard too many times from too many people who had meant it as a compliment and delivered it as an observation.

The second suture went in below the first. Caius worked upward from the inferior margin, the way the field manual recommended for wounds where gravity and movement would pull against the closure. The manual was somewhere in the pod\u2019s data stores, a document he had skimmed once during basic flight medical training and not thought about since. The information surfaced without effort—the same way flight protocols surfaced, the same way emergency procedures surfaced, the same way every piece of training he had accumulated in his career rose to conscious access exactly when it was needed and receded exactly when it was not.

His hands did not shake. They never did. And Voss was watching them, because there was nothing else to watch—the porthole offered only stars, the instrument panel offered only bad news, and the alternative was closing his eyes while someone else\u2019s fingers stitched the skin of his abdomen back together, which was an act of trust that Voss Ackermann had probably not performed in seven years and was performing now with his jaw locked and his pulse visible at the hollow of his throat.

The pulse. Caius could see it. The pod was too small for him not to see it, and the position required for the suturing placed his face approximately eight inches from Voss\u2019s exposed torso, which meant he could see the rise and fall of Voss\u2019s breathing, the ridge of each rib beneath skin that was paler than it should have been, the topography of a body that seven years ago he had known well enough to map without looking.

The old scar was at the seventh rib. A childhood injury—Voss had told him the story once, in the engine room of a training vessel, during a watch cycle that had stretched past three in the morning. He had fallen from a maintenance ladder at fourteen, reaching for a wrench his supervisor had dropped, and the rung had snapped. Four stitches. They had healed crooked because the ship\u2019s medic had been a propulsion technician cross-trained in first aid and his suturing technique had been learned from a manual, not from practice.

Caius had asked, at the time, whether it still hurt. Voss had said no. And then, after a pause that had been slightly too long to be casual, he had said that it only hurt when someone asked about it.

Caius had never asked again. Until now, when the scar was four inches from his left hand and the question was no longer theoretical. The scar was white and slightly raised, a seam in the skin where the body\u2019s repair mechanisms had done their best with substandard work. It was still crooked. Still the evidence of a fourteen-year-old boy who had reached for something he should not have reached for and paid for it in scar tissue.

The fourth suture went in. Voss\u2019s breathing hitched again—the anaesthetic was fading, or had never fully taken, and what was left of its efficacy was being consumed by each stitch faster than Caius could place them. Fifteen minutes. That had been the estimate. They were at twelve.

\u201cThe O2 gauge.\u201d Voss said it the way he might have reported an engine parameter—factual, neutral, a variable that required adjustment. \u201cIt\u2019s dropping faster than the initial estimate.\u201d

\u201cHow much faster.\u201d

\u201cI\u2019m calculating.\u201d

\u201cYou\u2019re also bleeding.\u201d

\u201cBoth are true.\u201d

The fifth suture. The sixth. Caius\u2019s field of vision had contracted to the wound and the needle and the blue thread that was slowly pulling Voss\u2019s body back together in a line of surgical knots. The rest of the pod had ceased to exist—the instrument panel, the porthole with its silent stars, the environmental monitor with its polite, indifferent chirps. There was only the skin under his hands and the pulse under the skin and the breathing that had gone shallow in the last two minutes, a controlled shallowness that Voss was enforcing on himself the way he enforced tolerance on an engine calibration.

Caius did not tell him to breathe deeper. He did not tell him anything. The suturing was a language that required no translation, and the silence that filled the space between the stitches was the same silence that had filled seven years, but it was changing texture in a way he could sense without being able to name. The silence had been a wall. Now it was a membrane. He could feel Voss\u2019s breathing through it, the way he had felt Voss\u2019s breathing through the thin partition between their bunks during training rotations, a rhythm that had made the dark feel like something holding steady rather than something closing in.

The seventh suture. The eighth. The wound was closing. The margins were aligning with the kind of precision that the field manual described as \u201cadequate\u201d and that Caius\u2019s hands delivered as \u201cexact.\u201d

The anaesthetic was gone by the ninth suture. Voss\u2019s exhale broke across his teeth—a sound that was not a word and not a gasp and not anything except the body\u2019s refusal to absorb pain silently. His pulse jumped. Caius saw it jump. He saw the muscle of Voss\u2019s abdomen contract under the needle, an involuntary response that the brain\u2019s pain suppression systems could not override, and he felt his own diaphragm lock in a sympathetic spasm that he did not allow to reach his hands because his hands did not shake and never had and would not start now.

\u201cAlmost done,\u201d Caius said.

Voss did not answer. His eyes were open and fixed on the overhead panel, where the red light had not changed shade but seemed to have deepened, the way shadows deepen just before a storm. His hands were flat on his thighs, the broken left held carefully still, the functional right curled into a fist that was not quite a fist, the fingers bent at angles that suggested restraint rather than surrender.

The tenth suture. The last. Caius tied off the knot and cut the excess thread with the field scissors, the blades biting through monofilament with a finality that felt disproportionate to the gesture. The wound was closed. A line of blue surgical knots crossed Voss\u2019s abdomen like stitching on a chart—tidy, evenly spaced, the work of hands that did not shake.

Caius taped a gauze pad over the sutures with three strips of sterile tape. His fingers brushed Voss\u2019s skin as he pressed the adhesive into place, a contact that lasted less than a second and registered with the clarity of something that would take longer than a second to forget. The skin was warm. Warmer than it should have been, or perhaps colder—the pod\u2019s thermal regulation was drawing too much power, and the ambient temperature had dropped three degrees since the launch, and distinguishing between a wound site that was warmer than normal and skin that was simply reacting to a cold environment was a differential diagnosis that would require equipment the pod did not have.

Voss lowered his shirt. The motion was slow and careful and required both wrists because his fingers could not grip the fabric. The bloodstained hem settled over the gauze, and the evidence of Caius\u2019s work disappeared beneath it, and the thirty inches of space between them felt briefly like more than thirty inches, the way a room feels larger when a door that was closed has been opened, even if only by a crack.

Voss turned toward the instrument panel. The motion cost him—the sutures pulled against the muscle, and his expression flickered in a way that would have been invisible to anyone not watching his face from eight inches away. He pulled up the O2 diagnostics on the secondary display, the numbers rendering in green against the red ambient glow like an ecosystem that had evolved to survive in a place where nothing was supposed to survive.

He looked at the numbers for a long time. Long enough that Caius could count his own pulse—sixty-two beats per minute, elevated by approximately four from his resting rate, which was a data point he filed alongside the other data points he was not examining.

\u201cThe leak rate,\u201d Voss said. \u201cIt\u2019s worse than the initial estimate.\u201d

\u201cHow much worse.\u201d

\u201cThe microfractures are propagating. There are now five breach points, not three. The aggregate atmosphere loss is point-eight-four percent per hour above the original curve.\u201d He paused, and the pause was a calculation, and the calculation was visible in the way his eyes moved across the numbers without seeing them. \u201cAt current consumption, factoring in two adult males at minimal metabolic output, we have approximately four hours of breathable atmosphere remaining.\u201d

Four hours. The rescue corridor was five hours away at maximum burn, assuming the beacon was still transmitting, assuming anyone was listening, assuming the survey vessel\u2019s destruction had been detected by the fleet\u2019s tracking network, assuming a chain of assumptions that started with \u201cif\u201d and ended with a window that was closing at three hundred metres per second.

Caius did not say any of this. He did not need to. Voss had done the same arithmetic—had probably done it before Caius finished processing the first variable, because Voss\u2019s mind worked in numbers the way Caius\u2019s hands worked in procedures: automatically, precisely, delivering answers that were correct whether or not anyone wanted to hear them.

\u201cIs the beacon still broadcasting.\u201d

\u201cYes.\u201d

\u201cSignal strength.\u201d

\u201cNominal. The pod\u2019s transponder is operating within design parameters. The rescue corridor is receiving our position.\u201d He paused again, and this pause was different—shorter, sharper, the pause of someone choosing not to say the next sentence. \u201cThey\u2019re receiving a position that is diverging from the corridor at approximately three hundred metres per second.\u201d

Neither of them spoke. The environmental monitor chirped. The stars outside the porthole were still silent and still, the survey vessel\u2019s debris field long since dispersed into an expanding cloud of fragments that would appear on tracking screens as an anomaly and then a statistic and then nothing.

Caius looked at the O2 gauge. Four hours. The number sat in the red-lit air between them like a third occupant, one that consumed no oxygen and required no sutures and could not be reasoned with or bargained with or ignored.

He reached for the oxygen flow regulator. It was a small dial on the environmental panel, calibrated in percentages of standard atmosphere. He turned it down—not to minimum, not yet, but down. The flow indicator dropped from green to amber. The air in the pod would grow thinner over the next hour, the oxygen partial pressure declining to a level that would keep them conscious but not comfortable, alert but not warm.

\u201cThat extends the curve,\u201d Voss said. \u201cBy approximately twenty-eight minutes.\u201d

\u201cI know.\u201d

\u201cIt also accelerates the onset of hypoxia symptoms. At the reduced flow rate, cognitive impairment will begin within three hours. Decision-making capacity will degrade before the four-hour mark.\u201d

\u201cI know.\u201d

Voss turned his head. The motion was small—a few degrees of rotation—but in the confined space it felt like a repositioning of something fundamental, the way a ship adjusts its heading by a fraction of a degree and arrives at an entirely different destination. His eyes were still grey in the red light, still the colour of storms and coolant and seven years of silence, and they were looking at Caius with an expression that contained multiple questions and none of the words for asking them.

\u201cThere\u2019s a decision to make,\u201d Voss said.

\u201cThere\u2019s always a decision.\u201d

\u201cThat\u2019s not what I meant.\u201d

Caius knew what he meant. The math was unambiguous. Two men breathing the same diminishing volume of oxygen, one injured and bleeding internally at a rate the sutures had slowed but not stopped, the other functioning and capable and occupying space and air that could, in a different configuration of variables, belong to only one person. The math said things that neither of them was going to say, because saying them would make them real, and the pod had enough reality in it already.

Outside the porthole, the stars maintained their ancient silence. Somewhere in the direction the pod was drifting, the rescue corridor traced a line through space that had been calculated for a vessel that no longer existed. The beacon was still broadcasting. The O2 was still falling. The pod was still intact, mostly, and the cold seeping through the microfractures was still bearable, barely, and the thirty inches of space between two men who had not spoken in seven years still contained both of them, still held their shared atmosphere and their separate silences and a question that neither of them had asked.

The question was simpler than the math. The question had been waiting for seven years, and it would wait a little longer, because the oxygen it took to ask it was oxygen they could not spare. Not yet. Not while the beacon was still transmitting and the curve could still be extended and the arithmetic of survival still had variables that had not been solved.

Caius pulled the two emergency blankets from the survival kit. They crackled in his hands—foil-thin, metallic, designed to reflect body heat back toward the source. He draped one over Voss without meeting his eyes, the foil settling over the bloodstained shirt and the sutured wound and the body of a man who had once been something else to him, something he had not named and could not name and would not name now, when names cost oxygen and oxygen was running out.

The second blanket he kept for himself. He did not put it on. He sat with it folded in his lap, the foil catching the red light in fractured reflections, and stared at the O2 gauge that was ticking downward with the patience of something that did not care how long it had been waiting and did not care how much longer it would wait.

Four hours. Twenty-eight additional minutes, if Voss\u2019s extension math was correct. A window of time that was both too much and not enough, filled with the breathing of two men who had survived the destruction of their ship and the collapse of their respective careers and the silence that had grown between those two events like scar tissue over a wound that had never been sutured.

Voss shifted under the emergency blanket. The foil rustled, a sound that was bright and brittle in the confined air. He did not look at Caius, but his voice, when it came, was pitched low enough that the environmental monitor\u2019s next chirp nearly covered it.

\u201cThe beacon will keep broadcasting.\u201d

It was not a question. It was also not a statement. It was something in between—a variable offered for confirmation, an equation that required a second set of eyes.

\u201cI know,\u201d Caius said.

He meant something different than what the words meant. He could hear the difference himself, a shift in the frequency of the silence between them, a harmonic that had not been there before the suturing and was there now, resonating in the thirty inches of red-lit air like a signal that no instrument could measure.

Neither of them named it. The O2 gauge dropped another increment. Outside, the stars kept their counsel, and inside, two men who had spent seven years not speaking to each other sat in a silence that had become, without either of them acknowledging it, a different kind of silence than the one they had been keeping.
