The planet below was meant to be simple. An away mission, a negotiation, nothing more than protocol and signatures—clean, efficient, forgettable.

But Captain James Tiberius Kirk had learned long ago: nothing in the galaxy stayed simple for him. Not for long.

The underground compound howled like a dying beast, every disruptor blast rattling its bones until the walls shuddered and split. The ceiling trembled above him, coughing down razors of stone that sliced fresh lines across his cheeks. Dust fell in suffocating veils, thick enough to choke on, scouring his throat raw with every breath. Smoke rolled heavy through the corridors—burning, acrid, stinging his eyes—and the metallic tang of ozone bled bitter and hot across his tongue. Somewhere overhead, a conduit screamed apart in a spray of sparks, showering searing heat across his skin before the passage fell back into twitching, uneven dark.

Jim pressed his spine flat against the freezing wall, dragging air into battered lungs that barely wanted to hold it. His ribs shrieked with every inhale, jagged pain spiking like molten glass where a rifle butt had slammed him square across the chest. The ache radiated deep, hollow, as though something had broken open inside him. Still he forced air in, jaw locked, lips cracked and bloodied. His phaser was slick in his grip, shaking with the tremor in his hand. Not fear. Not fear. Never fear. He ground the thought down to ash, clamped his knuckles bone-white around the grip until the weapon steadied. He’d clawed his way out of worse pits than this. He’d survive. He had to.

“Captain.”

The single word cut through the thunder, calm and deliberate. Spock’s voice—measured, anchored, urgency hidden beneath steel—rose from across the archway. “Five combatants advancing from the southern corridor. Their weapons are high-yield. At this proximity—”

“We’ll be vaporized,” Jim rasped, voice torn and raw, dust grating in his throat. He dragged his sleeve across his mouth, smearing blood, coughing hard enough that white fire tore through his ribs. “Fine. Tell me you’ve got something.”

Spock leaned just enough into the corridor. The ruined lamp above him sputtered red, painting his profile in sharp strokes: jaw tight, gaze honed, every line carved with precision. He looked carved from stone, unflinching. Calm didn’t soothe—it cut.

“I will draw their fire,” he said evenly. “You will disable the couplings. Once power is severed, they will be blind. The advantage will be ours.”

Jim’s heart slammed against the knife-points of his ribs. “The hell you will.”

“I will provide distraction.” No falter, no hesitation. The words landed with the finality of stone. A fact, not a proposal. Logical. Inevitable.

Another barrage tore into the compound, rattling stone down in showers, the floor bucking beneath Jim’s boots. Pain stabbed through him sharp enough to turn his vision white at the edges. He lunged forward anyway, seized Spock’s arm, fingers digging bruises into Vulcan flesh.

“Don’t you dare,” he snarled, voice shredded raw with terror he refused to name. “Don’t you dare throw yourself—”

But Spock was already gone.

He wrenched free, breaking cover in a flash of motion. His boots hammered the stone, the sound echoing like drumfire in the cavernous dark. Enemy disruptors shrieked to life, a rain of blistering blue-white bolts tearing into the hall. They screamed past him, chewed through walls, detonated in storms of sparks and thunder. Shards of molten stone rained down. The noise was deafening, rattling Jim’s teeth in his skull.

“Spock!” Jim’s roar split the air, fury ripping raw from his chest until it scalded his throat, tasted like iron. “Goddamn it!”

He forced himself forward, ribs tearing open with every step, pain grinding sharp as broken glass inside him. He slammed his phaser into the nearest panel and fired point-blank. Circuits screamed, shrieking sparks bursting outward, searing his palm to blister. The reek of scorched flesh and ozone turned his stomach. Overhead, lamps spasmed, guttered—then died, smothering the compound in absolute dark.

Chaos erupted like a living thing, tearing the dark apart. Shouts ricocheted through the corridors, boots crashing blind, disruptors shrieking in jagged bursts. Each blast ripped the void open in violent strobing light, freezing the world in shards of white-blue brilliance—walls splintering, stone erupting, bodies flung in half-glimpsed carnage.

Then—
A crash. Flesh against stone. Heavy. Final.

Jim stopped dead. Cold flooded him, scouring his veins to ice.

“Spock?” His voice broke into the comm, raw, strangled. Static answered, hissing hollow, a sound like emptiness itself.

He lunged forward, half-stumbling, one hand scraping jagged walls for balance. Every breath tore him open, ribs flaring like knives, lungs filled with fire. Still he drove on. His boot struck something solid. He pitched forward, crashing down hard, knees splitting raw against stone. His palms shredded open as he braced, fingers sliding across fabric—warm. Wet.

“Spock!” The name ripped out of him, a prayer torn ragged, a curse spat at the void.

The Vulcan sprawled boneless across the floor, uniform blackened where a disruptor blast had eaten deep into his shoulder. The stink of scorched flesh hit Jim hard, acrid and suffocating, bile burning his throat. Spock’s chest hitched shallow, rattling, every breath thin as spider silk, each one threatening to snap.

Alive. The word struck like lightning through Jim’s skull, sharp and blinding—but terror crashed in colder than vacuum. His hands trembled as he clamped down on the wound, and hot blood surged against his palms, thick, slippery, pouring far too fast. The heat slid between his fingers, staining them green. He couldn’t hold it back. Couldn’t hold him back.

“Stay with me,” Jim muttered, words breaking apart, his throat raw and strangled with fear. “You hear me? Stay with me, damn it.”

Spock’s eyelids fluttered. His eyes—usually sharp, steady, grounding—were glassy now, unfocused, darting sightlessly through the dark. His lips parted, shaping soundless words, the silence worse than any scream.

Jim’s pulse hammered in his ears, panic pounding like a second heartbeat. He swallowed it down, forced his shaking arms beneath Spock’s body, and hauled him upright. The Vulcan’s weight collapsed against him, all muscle slack, crushing. Pain flared white-hot through Jim’s ribs, a tearing fire that nearly drove him back to the ground. Still he heaved, teeth gritted, locking his battered body against Spock’s, dragging them both forward, inch by desperate inch.

“Come on. Come on,” he rasped, his voice hoarse, shredded, each syllable raw with need.

They staggered down the corridor together—Spock’s deadweight dragging him earthward, Jim’s own breath coming ragged and wet, copper flooding his tongue. His uniform clung to him, heavy and sticky with his own blood. Still he clutched Spock tighter. Still he refused to let go.

“Almost there,” Jim panted, teeth clenched against the pain, vision tunneling. “Almost there. You don’t get to quit. Not like this. Not on me.”

The walls warped, tilting in his sight, every step a fever-dream blur. Behind them came the hunt: boots pounding closer, shouts echoing sharp, disruptors whining high and lethal. He didn’t look back. Couldn’t. All that mattered was the beacon’s pulse ahead, that fragile flicker of gold slicing through the dark like a promise.

Salvation.

He stumbled into the chamber, knees threatening to buckle under their combined weight. Spock sagged heavier against him, head lolling, and Jim’s blood-slicked hands fumbled at his communicator. His breath hitched in broken, ragged bursts, chest barely expanding.

“Captain Kirk to Enterprise,” he gasped, words ripped from his lungs like a prayer torn raw from bone. “Two to beam up—NOW!”

And then the world shattered around them in a blaze of gold.

The transporter beam fractured them apart and rebuilt them in a blaze of gold, the roar of collapsing stone torn away and replaced by the sterile hum of the Enterprise. The deck steadied beneath Jim’s boots—smooth, solid, immaculate. Too immaculate. It felt obscene. He could still taste grit grinding between his teeth, still hear rock shrieking loose, still feel Spock’s deadweight dragging him down as they were ripped skyward.

For a fraction of a second, silence reigned.

Then chaos detonated.

“Captain on the pad!” Scotty’s voice snapped through the comm, ragged with panic and fear. The doors hissed open. Medics stormed in, boots hammering the deck. The metallic crash of equipment followed—biobeds screeching into place, trays clattering, tricorders screaming their alarms. Antiseptic stung the air, but it was drowned instantly by something darker, fouler: the copper tang of blood, the scorched chemical stench of burned flesh. It rolled off Jim and Spock in waves, smeared down their uniforms, dripping into the grooves of the pad.

Jim was still on his knees, hunched and unmoving, arms cinched around Spock in a deathlock. The Vulcan’s weight sagged heavy against him, head tipped at a terrible angle, body frighteningly slack. Blood had soaked through Jim’s tunic, scalding hot before it cooled tacky, welding them together in sheets of red and green. Every breath split fire through Jim’s ribs; his vision tunneled with black flashes, but still he crushed Spock closer, fists locked in scorched fabric. He wouldn't—he couldn't—let go.

“Medical team, move in!” someone barked.

Gloved hands reached for Spock’s shoulder.

Jim’s head snapped up, feral. His eyes burned fever-bright, glassy with exhaustion but blazing with fury. “Don’t you touch him!” The words ripped free as a ragged snarl, voice shredded by smoke and grit, but they cut the transporter bay in half. He hunched lower, curling tighter around Spock’s body, shoulders squared, a barricade of blood and bone. “He stays with me.”

“Captain, we have to stabilize—”

“You think I don’t know what you have to do?” Jim spat. His chest heaved, his body trembling, but his voice only sharpened. “You don’t move him until I say. Not one finger.”

Spock’s chest hitched faintly—shallow, rattling, barely a breath. The sound struck Jim like ice through bone, hollowing him from the inside. He pressed his forehead to Spock’s temple, lips brushing the Vulcan’s ear. Words tore out, ragged and breaking: “Stay with me. Don’t quit now. Don’t you dare. Not like this.”

The medics froze, caught between protocol and the raw, suffocating gravity of their captain’s desperation. Instruments hovered, scanners shrieked—but no one stepped forward.

Then the standoff shattered like glass.

“Jim!”

Bones barreled through the chaos, shouldering past uniforms and equipment alike. Gloves gleamed with sterilizer, face pale, eyes blazing with controlled fury. In a single heartbeat he took in everything—the dark, slick red soaking the deck, the waxen pallor of Vulcan skin, the grotesque slack of Spock’s body—and his gaze snapped to Jim, lethal and unyielding.

“You want him alive?” Bones roared. “Then let me treat him!"

Jim’s grip spasmed, fingers clenching, refusing to release. His face twisted, raw pleading splitting every line. “If I let go—” His voice shredded, broken. “If I let go, he won’t—he won’t make it.”

Bones dropped to one knee, seizing Jim’s wrist in an iron grip. “Listen to me, you stubborn son of a bitch,” he barked, voice fire wrapped in steel. “You holding him is killing him faster. You want to save him? Then let me in. Now.”

For a breathless heartbeat, Jim refused. Every muscle locked, arms trembling violently, jaw clenched like stone. Instinct screamed to shield, to never release, even as reason tore at him. Then Spock shuddered—another ragged, rasping rattle dragging from his throat, weaker than before. Jim felt it against his chest, fading. That sound—it hollowed him out, split him in two.

His body betrayed him before his will could. With a strangled curse, he ripped himself free, each movement raw, gut-deep, like tearing open his own ribs. He pulled back, arms slick to the elbows with warm blood, fingers still curling as if refusing to let go.

The medics surged forward, seizing Spock’s weight, lowering him onto the biobed in a storm of motion. Masks sealed over his face, hypos hissed, scanners screamed. The sterile hum of Sickbay was pierced by alarms, the sharp scent of antiseptic mingling with copper and charred flesh.

The emptiness left behind was unbearable. Jim staggered back, swaying as though the deck had tilted beneath him. Blood dripped from his hands in steady, obscene drops. His chest felt hollow, a vacuum where Spock’s presence had been—like a vital organ ripped from his body.

“Captain, you’re bleeding—” a medic started, reaching toward him.

Jim snapped back with feral speed, voice raw and ragged, torn by panic and pain. “I’m going with him!” He stumbled forward, body folding under the weight of agony, yet his gaze never wavered from the stretcher. “Don’t you dare take him without me.”

No one stopped him. Not after seeing the fire in his eyes.

The stretcher lurched forward, wheels screaming against the deck, medics shouting commands, voices slicing through the chaos. Jim lunged after them, fingers clawing at the bulkhead for balance, every step sending white-hot agony through his ribs. Vision flickered in fragmented bursts—light, shadow, blur—yet he pressed on, tethered only to Spock, staggering but relentless.

“Blood pressure crashing—line in, now!”

“Cardiac unstable—charge the infuser!”

The words shredded together like shards of nightmare, a jagged chorus in the storm. Jim clung to the single, precious sign of life: the faint, uneven lift of Spock’s chest beneath the restraints. Too shallow. Too slow. But still moving. Still here.

The Sickbay doors slammed open. Blinding white light poured over the corridor, cutting through the haze of blood and sweat. Medics surged forward in a coordinated storm, hoisting Spock onto a biobed with brutal precision. Monitors screamed red, hypos hissed sharp bursts, hands flew in synchronized urgency, and the sharp tang of antiseptic mixed with the copper bite of blood stung Jim’s nostrils.

Jim lunged forward instinctively, reaching for Spock, but strong hands slammed onto his shoulders, yanking him back. Nurses pressed against him, trying to hold him still. He tore free in a savage burst, crashing against the edge of the biobed. “Don’t you take him from me!” His voice cracked, raw and ragged, dripping with terror. “I’m not leaving him!”

“Jim!” Bones’ voice cut like a whip, sharp, unyielding. “Stop!”

The command hit Jim like a blow. His chest heaved, body trembling on the edge of collapse, yet he refused to release his grip on the stretcher. Bloodied hands curled tight, muscles taut, every nerve alight with defiance.

“Please,” he rasped, stripped bare, no captain left—only a man, raw and exposed. Eyes burning, fixed on Spock’s pale, slack face. “Bones…don’t let him go.”

Bones’ jaw tightened, eyes softening for a fleeting heartbeat, but then his steel snapped back. He stepped forward, voice sharp and absolute. “Jim, you’re not going in. Not now! Not while he’s this fragile. You stay here!”

Jim surged again, desperation fueling him. “I have to—he can’t—” He stumbled forward, body straining, following Bones into the storm of medics and machines.

“No!” Bones barked, grabbing Jim’s arms with iron grip. “You’ll get in the way! Stay outside, now, or you’ll lose him!”

The words cut into Jim’s gut like a scalpel. Nurses pressed against him once more, holding him back as his boots slipped in the spreading pool of blood. Jim’s body trembled, every muscle aching, chest hollow with helplessness, but Bones’ voice anchored him, forcing him to halt in the waiting room just beyond the Sickbay doors.

Through the glass panel, he saw the chaos unfold: medics swarming, hypos snapping, monitors blinking red with urgent alarms, Spock’s body strapped rigid to the biobed. Every second that passed was a jagged shard of panic in Jim’s chest. His gaze never wavered from the fragile rise and fall of Spock’s chest—the proof that he was still here, still fighting.

Jim pressed against the wall, boots sticky in blood, fists clenched so tightly his knuckles whitened. Every nerve screamed to surge forward, to touch him, to make sure he was alive. But Bones’ voice, commanding and unwavering, reminded him of the only thing he could do: wait. Watch. Hope.

He stayed rigid, body coiled and tense, blood still dripping from his elbows, heart hammering like a drum in his chest. And he didn’t move. Not an inch. Not until Spock’s eyes fluttered open—and met his. Not until he knew.

Hours had leaked away like blood into the ship’s veins. Outside the hull the Enterprise drifted calm against the scatter of stars; inside Sickbay, time had been reduced to the small, merciless measures of it—the electronic hiccup of a monitor, the hiss of oxygen, the steady, thin rasp of Spock’s breath. The room smelled of antiseptic and burnt flesh and something metallic that never left Jim’s hands, no matter how many scrub bays he washed them in.

Bones had fought like a man possessed. His gloves were slick with green blood, edges crusted with coagulated grime; his voice was raw, shredded from barking orders over alarms that screamed themselves hoarse. He had corralled chaos into strict, ruthless precision—lines, scans, hypos, regenerators—forcing the impossible into motion, until the work gave shape to the senseless. Against every grim calculation, Spock had survived.

But survival was a fragile, glittering thing, trembling on the edge of ruin: ribs rising and falling on a knife’s edge, lungs drawing breath like a man dragging himself across a canyon of pain. Spock’s skin, usually warm bronze, had drained to waxen pallor, tinged faintly green, life seeming to seep from him with every shallow gasp. His lips were thin, almost paper-white, trembling slightly with the effort of holding on. Each rise of his chest was a private war—a battle Jim could feel echoing against his own heart.

Jim hadn’t moved from the chair at the bedside. He was a map of hurt and refusal—ribs tightly bound with field tape so hard they throbbed with each breath, one arm in a sling, bruises spreading black and purple under his uniform. Bones had shoved a cot at his feet and told him to lie down; Jim had sat like a man keeping a post on the front lines. His jaw was set as if welded. His eyes were hollow, the edges rimmed with blood and lack of sleep. He looked like someone living on the raw edge of endurance.

He heard the change before he saw it—Spock’s breath stammered, a micro-falter in a rhythm they’d both learned to read. Jim was upright in an instant, a soundless violence in the way he slammed his hand onto the bedrail, knuckles gone white.

“Spock?” His voice came out as a ragged rasp. He sounded younger than he had in years, stripped to marrow.

Spock’s lids slid open like stone being pried free. At first his gaze wore the glassy haze of someone dragged back from the brink, then it focused and found Jim with that inevitability of a compass finding north.

“You should not be here,” Spock said, voice coarse with disuse, the words gravelly as if scraped from some dark throat.

Jim laughed, and the sound cracked—half relief, half rage. “Don’t you dare start with that.” He wiped his mouth with the back of his hand; the motion smeared a faint line of green. “You nearly gave me a heart attack.”

Spock’s breath rattled like wind through a ruined corridor. “You were never in danger. I ensured—”

“You’ve got a lot of nerve to dredge up all my fears.” The words punched out of Jim before he could swallow them. They were sharper than he’d planned, a blade slipped between them. His voice broke on the next line, raw with heat. “Don’t you give me that line. Do you think watching you go limp in my arms was not dangerous? Do you think I just watched and walked away?”

The room dimmed into a silence big enough to hold the scream of an alarm. The monitors ticked on, pitiless.

Spock’s face changed—something so small it could have been missed. Jim saw it: the faintest fracture in the Vulcan composure, like a crack in glass. It was the only thing that made his chest unclench a degree.

“I acted according to logic,” Spock said, voice thin around the edges. “It was the only means to preserve—”

“No.” Jim’s voice cut through like a blade, sharp and splintered, the word hurled with the weight of a weapon. “Don’t you dare bury this behind logic—not when my hands still reek of your blood, not when I felt your life slipping out from under my grip. Say it plain, say it as a man—you did it because you chose to. And don’t you ever think you can decide you’re expendable. Not to me. Not ever.”

For a long moment Spock said nothing. Then, with a motion that felt like confession, he lifted one hand. His fingers brushed Jim’s wrist—no more than a breath of contact—but to Jim it thundered like the sudden strike of a drum.

“I… had not sufficiently considered the impact of my choices upon you,” Spock murmured, the barriers in his voice lowered as if by force. The Vulcan control was gone; there was only the blunt, tremulous honesty in the words. “I will endeavor to amend my actions. For your sake.”

Relief slammed through Jim like a physical blow—sharp, dizzying, nearly enough to make him laugh until he choked. He managed a crooked, exhausted smile. “That’s a start.” He kept his hand on the rail a moment longer, holding on to the featherlight touch as if it were a lifeline. “Now rest. I’ll—I'll be right where I can see you.”

Spock’s eyes narrowed with a look that was not suspicion but a careful study, as if he were filing each scar, each freckle, every line around Jim’s mouth into memory. Then he inclined his head, slow and deliberate.

Jim hauled himself up with a groan that tore through muscle and bandage. Pain flared as he pushed from the chair, but he moved—because standing still felt like surrender. His boots made a dull scrape on the deck as he went for the door.

Bones intercepted him there, arms folded, jaw set like a stone barricade. He wore the exhaustion of a man who had watched too many die and still called each loss by name. When he spoke it was with a brittle edge.

“We need to talk,” Jim said, barely a question.

“Like hell we do,” Bones snapped. He stepped into the doorway and planted himself like a boulder. “That Vulcan stays right here. Not today. Not tomorrow. Not until I say he’s fit enough to dance. You hear me?”

Jim’s shoulders squared despite the fire dancing along his ribs. His voice dropped to something hard and small. “Bones, you know he won’t heal here. Machines and monitors won’t soothe him. He’ll starve himself awake in this room. You know that.”

Bones jabbed the air with a finger so hard it rattled Jim’s chest. “The hell he doesn’t. He stays here where I can keep him alive. And you—” his voice cracked, the iron splitting with helplessness—“you need to stop trying to kill yourself by proxy every time the universe gets inconvenient.”

Spock watched them both, silent and precise, an unblinking weight in the doorway between them. The Vulcan’s gaze took in everything and compensated for nothing; it was clinical and, in its way, intimate.

“This isn’t about dragging him into danger,” Jim said, the struggle of breath flattening his words into a confession. “This is about me asking you to trust me. Not to trust my rank. Trust me as—” He swallowed, feeling the word reverberate down his chest. “As his partner.”

The single word landed like a bomb.

Spock’s eyes softened, the change so small it might as well have been invisible, but it carried seismic force. His fingers moved against his knee—one tiny motion, a claim. He had heard. He had chosen.

Bones’ face cracked then. Fury bled into something rawer—fear, loss, the years of patching men together and watching them walk away. He sagged, the lines of his face suddenly worn with the cost of letting go.

“You’re both the most stubborn sons of bitches I’ve ever patched up,” he muttered, rubbing his face with a hand that smelled of disinfectant and determination. “Fine. Take him. But let me be absolutely clear—if he so much as twitches wrong, I’ll beam you back here and strap you both down myself.”

Jim let out a laugh that was nearly a sob. “Deal,” he said, and the word was soft, fierce with promise.

They moved then—not as captain and subordinate, not as med and patient, but as two men cementing a choice. Spock rose with a careful grace that belied the pain threading through his bones. Jim slid an arm around him, not as a gesture of command but of covenant: close enough to feel the slight tremor under Vulcan skin, close enough to share the breath that came with effort.

Bones grumbled about lunatics and early graves the whole way to the door, but his tone had lost its edge. He watched them cross the threshold and though he would never say it aloud, the set of his jaw told Jim all he needed to know: go, and bring him back to me alive.

Step by slow, deliberate step, they crossed into the corridor. Jim’s arm steadied Spock’s shoulders; Spock leaned into the support he’d so often supplied to others. They walked like men who had both been broken and found the parts that fit—battered, true, dangerously whole.

Inside Spock’s quarters, the air hung heavy, almost tactile, as if the Enterprise herself pressed for quiet, holding her breath along with them. Dim amber light pooled across the walls, molten and molten-gold, twisting shadows into long, sinuous shapes that slithered into corners. On the desk, a tablet lay open, Vulcan script etched with precise, almost obsessive care—unfinished equations frozen mid-thought, like the intellect itself had paused in contemplation.

Ritual objects stood in meticulous order: polished medallions catching the light like miniature constellations, an incense bowl empty but expectant, a meditation lamp dark and patient. Each object seemed to hum with latent purpose, waiting for the touch that might awaken it. Beneath it all, the ship’s quiet pulse thrummed through the deck, steady and unyielding—a reminder of motion, of survival, of the relentless world outside, turning even as they lingered on the knife-edge of thought and memory.

Jim moved carefully, each step a deliberate act of will. His right arm clung useless in its sling, and his left bore the weight of Spock, steadying him with a grip that was equal parts necessity and defiance. His ribs burned with every breath, jagged edges grinding together like broken glass beneath his skin. The pain was a living thing, tearing him apart from the inside, but he welcomed it—it anchored him. His shoulder screamed when he shifted, nerves sparking like live wires, but he refused to loosen his hold. The grip he kept on Spock’s wrist was ironclad, not just to keep him upright, but to remind himself that he was here, alive, and would not let Spock fall.

Spock’s body was rigid, his posture as composed as Vulcan discipline could muster, but Jim could feel the truth of him. The faint tremor in his balance, the shallow rhythm of his breath, the fraction of weight leaned into him—the cracks in his armor. Jim bore it silently, as though his own breaking body was a price worth paying to shield Spock’s faltering strength.

When they reached the bed, Jim lowered him down with reverence. Every movement was measured, as if Spock were something both indestructible and impossibly fragile. Spock sat stiff at first, shoulders squared, jaw locked, but the lines etched deep around his eyes betrayed him. Only when Jim’s hand lingered at his shoulder did he finally yield, lowering against the mattress with the smallest of surrenders. His breath left him in a controlled exhale, quieter than a sigh but heavy enough to shiver through the silence.

Jim lowered himself beside him, his own body screaming in protest. The shift of weight was agony—white-hot knives driving into his ribs, his vision sparking for an instant—but he did not flinch away. Pain was nothing compared to the need to stay close. Their shoulders brushed, their silence thick with everything unsaid. The quarters seemed to close in around them, shadows drawing tight like a cocoon, pressing them together in the dimness.

For a long time, their only language had been breath and survival.

Jim’s breath came ragged, each inhale scraping raw, tearing through his throat like glass shards dragged over steel. His chest heaved in violent, jagged rhythm, every expansion grinding splintered ribs together with the soundless agony of breaking wood. Lungs clawed and tore inside his ribcage, desperate for air, too damaged to hold it without fire lancing outward. Pain was not confined—it coursed through every fiber of him, relentless, corrosive, a white-hot current that tunneled into bone and marrow.

Spock’s breath was the counterpoint: shallow, measured, a discipline hammered into flesh and mind. Each inhale carried the stillness of ritual, each exhale the illusion of control. But beneath that precision, the faintest tremor threaded through, as if his body betrayed what his mind locked away. The discipline was a mask; the storm pressed hard against its edges.

Around them, the Enterprise hummed, the low vibration of her engines filling the transporter room like the heartbeat of a leviathan—steady, eternal, a tether keeping them both from vanishing into void.

When Jim finally forced sound through his ruined throat, it was no longer a voice but wreckage. Frayed by shouting, scoured by fear, it grated like twisted metal sparking against stone.

“I don’t want a first officer who throws himself in front of every knife meant for me.”

The words fell jagged, breaking against the silence. He wrenched the rest out from somewhere marrow-deep, torn and splintered like shrapnel being pulled through flesh.

“I don’t need a shield, Spock. I need—”

The truth caught, convulsed in his throat like something too vast to pass through. His chest spasmed, his ribs flaring agony as if the words themselves cut him. But he dragged them forward, bleeding them out raw.

“—I need a partner. Someone who stands with me.”

Spock turned then—slow, deliberate, a motion thick with ritual, as though each fraction of movement carved away layers of distance. The dim amber glow caught his face in planes of fire and shadow, stripping command away until only the unmasked man remained. His gaze locked to Jim’s—not dissecting, not measuring.

Recognizing.

He saw the truth: the heart beneath bravado, stubborn and terrified; the grief coiled tight behind swagger; the impossible weight of survival carried alone. He saw the raw, unshielded soul Jim had never let anyone bear witness to. Not a captain. Not a legend. A man, asking not for protection but for equal ground.

Spock lifted his hand. Fingers hovered in the fragile space between them. The pause stretched, heartbeat into heartbeat, silence trembling with unspoken vows. Then, with the precision of one who knows the edge of restraint too well, he crossed the final inch.

Two fingertips brushed Jim’s. Bare contact. A whisper of skin.

It detonated.

The jolt tore through Jim like the collapse of a star, annihilating and infinite. His lungs seized, ribs blazed white-hot, muscles convulsed under the surge. Pain sharpened into brilliance, but beneath it something older surged awake—wild, boundless fire, searing every nerve, every synapse, down to marrow itself.

This was not touch.

This was communion.

Ash and rebirth collapsed into a single instant—nothing and everything fused in one annihilating pulse.

Spock’s voice followed, low and inexorable, each syllable dropping like iron hammered into stone:

“Then we are in agreement.”

Not logic. Not compromise. A vow, weighty and unbreakable.

Jim’s throat convulsed, a jagged half-sob, half-gasp tearing free. No medkit, no hypo, no human comfort had ever steadied him the way the whisper of Spock’s fingers did. His body shuddered, ribs grinding, breath stuttering, as he leaned forward and pressed his mouth to Spock’s.

The kiss burned—not frantic, not desperate, but fierce, defiant, carved from ruin and made into promise. Fire poured into ash, vow made flesh. A pledge never to fracture, never to flee, so long as breath existed in either of them.

Their breaths tangled. Pain still raged through Jim—every inhale slicing his lungs, every exhale scraping ribs raw. His body spasmed under the strain, every nerve flaring white-hot. He felt flayed, stripped to the bone—yet alive, tethered.

Spock’s breath remained measured, but tremors threaded the cadence now, each one betraying the quake inside him. Amber eyes held Jim’s, unflinching. They saw not command or bravado but the man beneath—scarred, reckless, terrified, burning. Sacred.

Jim convulsed again, ribs grinding as the bond pulled tighter. Pain lanced, searing brilliant white across his chest—but beneath it, connection roared. Fire older than fear, older than pain, blazed unrestrained.

Spock shuddered, feeling every echo of Jim’s agony through the link—phantom blades tearing across his chest, nerves thrumming under the strain. Yet he did not waver. He anchored himself, an immovable wall, a harbor for the storm Jim unleashed.

Time fractured. Pain ripped. But certainty burned through the fractures, heavy as gravity itself. A single truth lit in Jim’s chest like a star: Not alone. Never again.

A sound broke from him, raw, guttural, half scream and half sob. His hand clenched Spock’s, bruised knuckles scraping, desperate for tether, for anchor, for life itself. His mind roared through the bond: I cannot lose you. I cannot.

Spock answered—not in English, but in Vulcan, the words vibrating in Jim’s marrow, searing nerve and bone alike:

“K’diwa nash-veh, Thyla. Nash-veh t’veshaya. Nash-veh t’nash-veh.”
(You are mine. I am yours. Wholly. Always. No shadow will touch us.)

The vow branded itself into Jim’s chest like molten steel. His reply broke free without thought, raw and unrestrained, pulled from the marrow of him:

“K’diwa nash-veh, Thyla. Nash-veh t’veshaya. Nash-veh t’nash-veh.”
(I am yours. Completely. Always.)

The bond ignited into a supernova. Pain shattered, bodies and minds colliding, fusing in fire. Every heartbeat, every pulse of air, every nerve-end blazed shared. Control and chaos, logic and instinct, Vulcan and human—no longer separate currents but a single roaring tide.

Spock absorbed Jim’s agony. Jim absorbed Spock’s certainty. Terror became devotion, pain became anchor, chaos became fire that burned steady and unbreakable.

Spock’s vow rang through Jim’s blood, every syllable a brand of eternity:

“Thyla, k’diwa nash-veh. I claim you wholly. You are mine, and I am yours. Forever.”

Jim trembled, body shuddering against pain and fire, and answered in kind, fierce, ragged, unshakable:

“K’diwa nash-veh, Thyla. I am yours. Always.”

The bond locked.

Not tentative. Not fragile.

Reforged in fire and agony. Tempered into steel. Eternal.

No longer two broken men staggering under ruin, but a single flame—bound by marrow, blood, fire, and infinite love.

The conflagration blazed, terrible and luminous, an indestructible tether stitched into bone and nerve. A fire that would burn until the end of stars—and beyond.
