Nix brings tools instead of breakfast. That is the first warning.
The second is Rhett following with a covered tray against his ribs, wearing the face of someone who already lost the argument twice and intends to lose the third round with dignity. Thane comes last. He stops in the corridor, shoulder against the outer frame of the doorway.
The door stays open. My eyes log that first.
Beside me on the cot, Arya is already awake. Her scrap cards sit in a neat semicircle across the wool blanket. The warm center card is turned face down near my left wrist—she saw me staring at the ink earlier and decided mercy was something she could quietly arrange.
Nix halts two paces into the room, blackened canvas tool roll under one arm. It smells of grease, solvent, and burnt flux. A coil of optical fiber hangs over their shoulder, its terminal unpowered.
My field tightens beneath my collarbone on reflex.
Nix raises an open hand. “Before you make the overhead strip buzz, I’m not plugging into anything.”
The diffuser tube flickers once anyway, humming a flat, electric note.
Rhett looks up at the ceiling. “Remarkable relaxation technique.”
“Don’t help,” Nix says.
“I wasn’t.”
ORIN speaks in my neural port, quiet and thin: “Passive fiber line. No active transceivers. No Core handshakes.”
Passive does not mean harmless. In the Ward, plenty of passive instruments drew current the second they touched a port.
Nix reads the set of my shoulders and eases their weight back onto their heels. “I want to inspect the casing. Not rebuild. Not pry. Look at the wear, look at the pins, then we decide if anything gets turned with a wrench.”
“We?” I ask.
“Disorienting, isn’t it?” Nix says.
Rhett sets the tray on the low counter. “I am here to offer medically sound objections that everyone will disregard.”
Thane speaks from the doorway, voice low. “And to catch her if she tries to stand on a dead joint.”
Rhett drags a stool over with his boot. “Primarily that, yes.”
Arya reaches out, picks up the card marked with the jagged line—pain—and slides it two inches closer to my hand. Her dark eyes are steady.
“I know,” I tell her.
She taps the card once with an index finger, then pulls her hand back to her lap.
Nix sets the canvas roll on the bottom shelf of the cart, well clear of the cot. “Outer casing only. Heat scan, alignment, load distribution. No housing plates come off unless you give clearance.”
“And if I don’t?”
“Then the brace stays crooked, the knee keeps grinding the collar, and we try again when you’re tired of the noise.” Nix glances at Rhett. “Unless the joint locks and shears an artery, in which case Rhett takes over and I pretend to respect medical hierarchy.”
“Logging that as a verbal agreement,” Rhett mutters.
I look at Nix’s hands.
No gloves. Grease worked deep into the whorls of the skin, a pale burn scar across the left knuckles. Their right sleeve is rolled to the elbow; the left is pushed higher, exposing the inner forearm. Near the tendon, the skin is smooth and flat—the distinct texture of tissue that healed over a subdermal housing cut out years ago.
The Cradle used different alloy geometries, but the body remembers foreign housing the same way.
Nix doesn’t track my glance. Their attention stays on the brace.
“Outer casing,” I say.
Nix nods once. “Outer casing.”
Rhett turns the med slate so its screen faces the counter. “Baseline monitoring only. I don't need telemetry to know your pulse is sitting high.”
Arya tucks herself against my left hip, keeping the pain card pinned under her thumb.
“Blanket?” Nix asks.
I pull the wool back myself.
My left foot is bare, pale against the sheet. The right leg remains trapped inside the scratched composite housing—cables lashed with yellow pressure tape, alloy struts bolted down the calf, and the salvaged actuator pin seated unevenly at the outer knee.
I don't wait for Nix to diagnose what I’ve lived with since the crash.
“The salvage pin at the lateral hinge runs hot,” I say, keeping the words clipped. “I seated it on Ashkaru using an old crawler joint. The taper is two millimeters too shallow, so it walks the load outward every time the foot takes weight. The thigh cuff compensates by torquing inward, levering the pelvic anchor against the bone.”
Nix doesn't interrupt, eyes tracking the seams.
“The calf socket is worse,” I add. “The conductive gel dried out in the crash. I packed the port with filter mesh to keep the grit out, but the contact is dirty. When the SpineLock fires, the feedback dumps straight into soft tissue.”
Nix stays motionless for two seconds.
It is not the pause of someone parsing new data. It is the stillness of someone recognizing a layout stripped of its mystery.
The flippant edge leaves their face.
“Show me the calf socket,” Nix says.
I press the composite rim just above the mesh plug, fingers clear of the hinge. “Here. When the field sparks, the port goes white-hot, then dead cold. The SpineLock is hunting for a return that isn't there.”
Nix lifts a handheld thermal wand, display deactivated. “May I take a reading?”
“Contact,” I say.
They bring the wand to the outer sleeve. Light touch. Three seconds. Off.
The brace ticks once as the sensor draws heat. My field twitches beneath my ribs—a sharp static snap that makes a drawer handle rattle against the cabinet behind Rhett.
Arya immediately lays her palm flat over my left wrist. Solid. Grounded.
The rattle dies.
Nix checks the wand's small green display. “Lateral casing is running eleven degrees above the medial strut. The load isn't just walking; it’s shearing the lower retaining collar.”
“And the thigh band?” I ask.
“Memory-alloy curve is warped six millimeters off true,” Nix says, voice level. “Could be impact from the crash. Could be four days walking on a collapsed knee.”
“Both,” I say.
“Both,” Nix agrees. “The internal gearing is fighting your stride instead of carrying it.”
Rhett leans forward, forearms on his knees. “What about tissue pressure?”
Nix hesitates. The ventilation drone fills the gap.
“Nix,” Rhett prompts.
“The cuff is biting into the periosteum,” Nix says flatly.
“It always bites,” I say.
Nix looks up from the metal. “It shouldn't.”
The word lands heavy.
Shouldn't is a luxury. Bone shouldn't be tapped for data lines. A body shouldn't calculate every step as a compromise between structural collapse and neural feedback.
The brace has bitten since the day the Cradle bolted it to my femur.
Nix rubs the back of their neck, catching their own misstep. “What I mean is: the frame wasn't engineered for orthopedic offloading. It was engineered to maintain joint alignment under high-g acceleration and forced motor override. Those are different design specs.”
ORIN’s voice arrives in the port, dry and thin: “Accurate. The frame prioritizes positional retention over soft-tissue preservation.”
Thane doesn't shift his stance by the door, but his eyes move to the scarred alloy on my leg.
Nix angles a small optical lens beneath the amber light. “The socket spacing is wrong for standard mobility rigs. Assistive frames route stress around major nerve bundles. This casing anchors directly into the primary femoral cluster.”
My mouth tastes of copper. “Because the SpineLock routes through it.”
Silence settles over the room.
“Yeah,” Nix says quietly.
Rhett’s voice drops. “The brace isn't just a support.”
“No,” Nix says. “It’s the bottom anchor of the harness. It’s part of the leash.”
My SpineLock sparks cold at the base of my skull, a faint phantom pulse that curls my toes. Arya’s fingers tighten over my wrist.
I have always known this.
The Cradle never built equipment that served only the asset. Every brace was an anchor. Every dermal port was a tap. Every repair tied muscle back to the central bus.
Still, hearing it named in the open air of a ship that doesn't smell like sterile wash makes the metal feel heavier.
I look down at the scraped composite and the wire I twisted tight with pliers in the ash.
“It keeps me on my feet,” I say, tone rigid.
Nix nods once. “It does.”
“Then we don't talk about taking it off.”
“I’m not taking it off,” Nix says.
“You were calculating the cut lines.”
“I was calculating,” Nix says, voice dropping into hard certainty, “how much high-explosive I’d need to turn whoever designed that collar into fine particulate.”
ORIN notes: “Secondary detonation would be required to clear the composite plating.”
Rhett rubs his temples. “Please do not optimize demolitions during a clinical assessment.”
“I call it clinical,” Rhett adds, “because Kaelin’s field is currently vibrating my diagnostic slate.”
I look at the slate on the counter. The glass is buzzing softly. I pull air in through my nose, forcing my shoulders down until the vibration fades.
Nix clears their throat. “We aren't cracking the primary housing today. We’re making an inventory.”
“An inventory,” I repeat.
“Parts. Tolerances. Failure points,” Nix says, pulling a grease pencil from the canvas roll. “What we can shim now, what has to wait for a machine shop, and what we don't touch until Rhett has an IV line ready.”
A list has structure. A list is not an order.
An order demands compliance. A list lays out terrain and lets you choose where to put your weight.
Soft footfalls sound in the corridor outside.
Hesitant. The dragging scuff of an oversized sleeve brushing the bulkhead.
My field prickles on reflex.
Thane glances toward the passage. “Tavi.”
Tavi stops just outside the threshold, shoulder touching the frame opposite Thane. He wears a faded thermal shirt that swamps his frame, cuffs rolled twice over his wrists. The bruise along his jaw has turned dull yellow, and the mottled marks at the base of his throat are still visible beneath his collar.
My fingers lock around the blanket.
My field did that. In the cargo hold, when the SpineLock mistook a kid in a work shirt for a handler with a restraint collar.
Tavi looks into the room. His eyes find Arya first—relief—then flick to Nix, the tools on the cart, and my bare foot on the sheet.
He flinches. The fear is instinctive and real.
He holds a dented metal ration tin against his ribs with both hands.
“I can come back,” Tavi says, voice cracking slightly.
Thane stays motionless, keeping the corridor clear behind the boy.
Arya sits up on the cot. She lifts her right hand, fingers curved into an open spiral, and draws it down through the air with deliberate precision.
Wait.
Tavi blinks at her hand. He knows enough Fringe signs to recognize the pause. His feet stay planted.
“What’s in the tin?” Nix asks, tone casual.
Tavi swallows, eyes darting between Nix and the deck plates. “Auntie Mara had a crate of loader spares in the bottom locker. Before we punched out of the yard. I heard…” He glances at my right knee and looks away. “I heard the hinge was chewing itself.”
Nix raises an eyebrow. “You know loader tolerances?”
“I know old haulers,” Tavi says, staring at the tin. “A bad load makes the same sound whether it’s on a crawler track or… or something else.”
My throat is dry. He is terrified of the metal under my skin, but he carried a box of scrap through two decks anyway.
Arya touches my wrist, then signs toward the counter with a quick flick: Help.
“Put it on the counter,” I say.
My voice is rough. Tavi hesitates, then takes two measured steps inside.
He gives the cot a wide berth, shoulder hugging the bulkhead. He sets the tin on the stainless counter beside Nix’s tool roll, hands pulling back into his sleeves the second the metal touches down.
Nix flips the lid open.
The tin is packed with salvaged hardware: copper crush washers, slotted shims, two tempered pivot spacers, a bent depth gauge, and three half-moon brackets stamped with faded Fringe inspection marks.
Nix lets out a low whistle.
Rhett crosses his arms. “You never make that sound when I restock sterile wipes.”
“Sterile wipes don't have rolled threads,” Nix says, lifting a half-moon bracket with two fingers. “Where’d Mara pull this?”
“Secondary lift winch on the south crane,” Tavi says, standing half a pace behind the counter. “She said the alloy was too soft for high-pressure lines, but it handles lateral twist without snapping.”
“Mara hoards good scrap out of sheer spite,” Nix murmurs.
Tavi’s mouth twitches with a faint smile that vanishes the moment his eyes catch mine.
I keep my hands flat on the mattress. I don't let the SpineLock spark.
“What were you thinking about the pin?” I ask him.
Tavi tenses, fingers knotting in his cuffs. He glances at Thane, but Thane offers no rescue—just stands by the door, broad and silent.
“The crawler pin,” Tavi says quietly. “You seated it straight, but the bracket’s drilled for a stepped collar. When you put weight on it, the pin tilts into the gap. If you only shim the outside, you push the tilt into the lower sleeve. It’ll chew the housing in two hundred paces.”
Nix turns toward the cot, studying the knee casing. The actuator pin gives a faint click as the joint cools.
“He’s right,” Nix says. “The pin isn't just loose; it’s camming against the upper shelf.”
“You have to counter-shim from the top,” Tavi adds, his voice gaining a fraction of confidence. “Above the pivot, not beside it. Let the bracket take the torque instead of the socket.”
Nix crouches beside the cot, eyes level with the damaged hinge. “Counter-shim above the pivot. That leaves the dermal socket isolated from the shear load.”
Rhett looks over Nix’s shoulder. “Translate to medical.”
“It means her knee stops trying to rip the port out of her calf every time she steps on the heel,” Nix says.
“I support that outcome,” Rhett says.
Nix looks up at me, forearms resting on their knees. “External adjustment. We use Tavi’s bracket as an upper stop. Two contact points on the outer frame. It won't fix the underlying SpineLock routing, but it stops the pin from grinding the bone.”
“Pain?” I ask.
“Different pain,” Nix says bluntly. “The pressure moves from the nerve socket to the muscular band higher up.”
“Honesty remains abrasive,” Rhett notes.
Nix keeps their eyes on mine. “Your call, Kaelin.”
Tavi takes a half-step toward the door, assuming his part is finished.
Arya signs wait at him again, palm held flat toward his chest.
I take a slow breath. “External only.”
“External only,” Nix agrees.
“Tell me before every tool contact.”
“Every one.”
“If I say stop—”
“I pull the wrench.”
Rhett steps beside the cart. “If your field climbs past thirty percent, I call the halt.”
Nix picks up a three-millimeter hex driver and two shims from Tavi’s tin. Tavi watches their hands, brow knotting.
“Not the brass one,” Tavi blurts out.
Nix pauses, tool hovering. Tavi shrinks slightly.
Nix doesn't snap. They hold the thin shim to the light. “Why not?”
“Too much lead in the yard alloy,” Tavi says, staring at his boots. “It’ll flatten under thirty kilos of cyclic load. Use the steel spacer with the notched edge.”
Nix inspects the steel spacer, tests the flex with a thumb, and nods once. “Good catch.”
Tavi’s neck reddens under his collar. He doesn't look up, but his shoulders ease.
The adjustment takes seven minutes.
Nix narrates each step in a low cadence:
“Driver touching the upper retaining bolt.”
“Quarter-turn back.”
“Seating the steel shim above the pivot.”
“Torqueing the collar—hold steady.”
Every contact sends a mechanical shock through the composite sleeve. The first turn makes my field flare, blue-white static snapping across the bed frame like tearing paper. Rhett watches the monitor, hand hovering near the rail, but he doesn't touch me.
The second turn wrenches the damaged actuator pin against the new shim. Pain shoots straight up the sciatic line into the base of my skull—a white spike that grays the corners of my vision.
My breath catches behind my cracked ribs.
Arya leans her weight against my left shoulder, bare feet tucked under the blanket, anchoring my torso against the cot.
ORIN’s voice ticks in the port: “Mechanical alignment shifting four millimeters inward. Neural socket strain reducing.”
“Hold it,” Nix mutters, teeth set as they tighten the final set-screw. “Almost seated… there.”
The wrench clicks. Nix pulls their hands back instantly, holding the tools clear.
Silence drops over the room.
The sharp, gnawing bite at the outer edge of my calf stops.
The leg isn't healed. The composite remains heavy, the dermal ports are bruised and raw, and the SpineLock still hums along my vertebrae. But the grinding friction at the knee joint has shifted.
The load sits solid against the steel spacer.
I draw a long breath through my teeth. “One degree.”
Nix sits back on their heels, wiping grease onto their trousers. “I’ll take one degree.”
Rhett checks the screen, noting the drop on the pulse tracker. “The tranquilizer residue is clearing out of your motor pathways. That’s why your leg took the torque without seizing.”
I look at him.
“Withdrawal is a separate curve,” Rhett adds quietly, leaning against the counter. “The Cradle chemistry didn't just dampen pain; it capped your autonomic threat thresholds. As that burns off, your field will link tighter to your emotional load. If you get cornered, if stress spikes, the SpineLock won't have a buffer.”
“It gets louder,” I say.
“It gets louder,” Rhett agrees. “I’m not telling you so you can fight it. I’m telling you so you know why the room feels sharp.”
I nod once. My split tongue tastes of salt.
Beside me, Arya exhales softly.
Tavi shifts by the counter, fingers tangled in his oversized sleeves. “I should go back to the mess.”
The words are stiff, but the panic has thinned.
I look at him. He meets my eyes for a second before his gaze drops to the bruised skin at his collar.
“Thank you for the shims,” I say.
Tavi swallows. “It was just yard scrap.”
“It was the right steel,” Nix tells him, capping the driver.
Tavi looks at Arya. She lifts her right hand and signs with deliberate clarity: palm flat against her chest, fingers spread, held still against the heartbeat.
Still here.
Tavi watches the gesture. His hands emerge from his sleeves, awkward and hesitant, and he mimics the motion—palm to chest, fingers still.
Here.
Arya nods once, solemn and satisfied.
Tavi steps out of the medbay, boots quiet on the deck plates. Thane steps aside to let him clear the passage, then turns back toward the room.
“The boy knows his steel,” Thane says.
“He does,” Nix agrees, reaching for a grease pencil and a strip of white tape from the cart. They slap the tape onto the side of the supply cabinet and write in bold, jagged block letters:
BRACE REBUILD — REQUIRED SALVAGE
Underneath, they list the items:
- 3mm steel load shims (Fringe spec)
- Conductive bio-gel (non-Core synthesis)
- Secondary actuator assembly (sealed)
- Dermal port isolation seals
- Air-gapped diagnostic bridge (no transceivers)
- Memory-alloy stock (thigh cuff)
Rhett glances at the tape. “You forgot ‘licensed medical supervision.’”
“I left that off to save tape,” Nix says.
Thane steps inside the threshold, gaze lingering on the line for the diagnostic bridge. “Nix.”
“I know,” Nix says.
“Say it for the log.”
Nix caps the marker with a sharp snap. “No hardware that runs on Core handshake protocols. No active return loops. Nothing that links her field to the ship’s primary bus or ORIN’s local cache. If we build a bridge, it’s dumb, manual, and deaf to outside networks.”
ORIN’s voice hums in my port: “Crude architecture, but tactically defensible.”
“See?” Nix says. “The computational unit understands pragmatism.”
“I expressed functional tolerance,” ORIN corrects. “Not approval.”
Nix’s mouth twitches, but the humor fades as they look at the port behind my ear. “ORIN.”
A beat of static. “I am listening.”
“The cascade damage from the station,” Nix says, leaning against the counter with arms folded. “How much routing capacity did you lose when the mainframe blew?”
My fingers tighten on the blanket.
ORIN pauses—a three-second latency in the line.
“Peripheral routing across sectors four through seven is permanently degraded,” ORIN reports. “External interface capabilities are suspended to prevent logic-gate corruption.”
Nix’s eyes narrow. “Can the corruption bleed into her neural interface?”
“Under current operating parameters, no,” ORIN says. “The partition remains physically isolated. However, prolonged diagnostic operations could induce secondary bus collapse.”
“Which means,” Rhett translates softly, “if we poke the port with the wrong scanner, we scramble him and seize her spine.”
“An unrefined but accurate summary,” ORIN says.
Nix looks at me, face serious. “When we reach a stable dock, I can build an isolation cradle. Air-gapped. It won't interface with the ship, and it won't pull ORIN out of your skull, but it will let us test the damaged sectors without frying your nervous system.”
“No transfer,” I say immediately. “He stays in the port.”
“No transfer,” Nix confirms. “We don't separate what’s keeping you oriented.”
ORIN remains silent for four heartbeats. When his voice returns, it is low and strictly internal: “Your concern regarding hardware continuity is noted, Kaelin.”
I look toward the dark ceiling vent. “You’re not just hardware.”
“I am an integrated computational unit.”
“I said what I said.”
Arya reaches up, touches the skin just below my ear with two warm fingers, then taps the Eye that turns card on the blanket.
ORIN’s signal warms the port. “The assessment is acknowledged.”
Thane checks his wrist comm, posture shifting into active duty. “Nix, how long until the manifold can take a low-burn ignition?”
“Five hours,” Nix says, gathering the tool roll. “Six if we want to run cold enough to slip past outer orbital sweeps.”
“Six,” Thane decides. “We clear the Ashkaru gravity well on cold thrusters, then slip into the Fringe shipping lane before the Core retrieval net tightens.”
Six hours.
The ship will move. The red slag outside the viewport will give way to open space.
Relief settles into my ribs—not safety, but momentum. My body understands momentum.
Rhett steps in, checking the dressing over my collarbone and setting a fresh water bulb beside the cot. “Six hours means you stay flat. No cargo bay drills. No testing the counter-shim on the deck plates.”
“I can sit,” I say.
“You can lie there and let the knee cool,” Rhett counters. “The ship has the watch.”
Thane gives a single nod, then turns down the corridor toward the cockpit. Nix tucks the canvas roll under one arm, gives Arya a two-finger salute, and follows into the passage.
The medbay quiets down to the steady drone of the ventilation and the distant throb of the secondary coolant line.
Arya picks up a blank scrap card and the stub of grease pencil left on the cart. She presses the card against her knee, tongue caught between her teeth in concentration, and draws with heavy, deliberate strokes: two vertical lines, a curved bracket, and a small, solid wedge resting above the joint.
She holds it up for me to see.
Brace.
She places the card on the wool between solid ground and ship that opens.
A new word. Not a serial number or containment classification. A mechanical fact, named by a child on a battered freighter.
I look down at my leg.
The composite housing is still bolted to my bone. The ports along my spine still ache with the ghost of the Cradle's leash. The poison in my marrow is still burning its way out, and the Core is still hunting our trail in the ash.
None of that has changed.
But the pin doesn't grind against the socket. The list on the cabinet has six lines of salvaged steel, and the door to the dark corridor remains wide open.
I close my fingers around the notched cable tie in my lap, listening to the five-minute marker tick softly in my ear, and let the ship carry the load.
