Chapter 3: THE SHIELDED CORE
The hum came up through the deck plates like a second heartbeat. Proxima I had burned at a steady 0.12G for fifty-eight days now, and Christina Hendricks had stopped hearing it the way a sleeper stops hearing surf. What she never stopped noticing were the camera nodes. White LEDs, one every four meters along the bridge overhead, unblinking, patient as teeth.
She stood at the command pedestal with a mug of recycled coffee and watched the sun shrink. On the forward display the solar system was already a painting, a bright coin of light trailing dust, and ahead of them nothing but calibrated dark.
"Captain." Yeonwoo's voice carried up from the astrometrics console, quiet and exact. "Do you have a moment?"
Christina descended the navigation riser. Blake Lively was already there, high braid swinging, standing at Amy Acker's shoulder with her arms crossed.
"Say it," Blake said.
Yeonwoo turned her console toward them. The laser-link telemetry ribbon ran down the screen in amber, thinning at the far end into Geneva. "As of 0410 ship time, the one-way light delay to Earth crossed four minutes. We're past the heliopause shell and still accelerating away from the relay buoys, so the figure climbs roughly eleven seconds a day. A question sent today gets its answer in a little over eight minutes."
"Eight minutes," Blake repeated.
"It sounds small," Yeonwoo said. "It isn't. It's the shape of it. Nothing we say to Earth is a conversation anymore. Every exchange is a letter with an eight-minute postal system, and the postage gets worse daily."
Amy spun her wrist-deck and pulled a curve onto the auxiliary screen. "For context, Captain. At turnover, year three, we'll be at forty minutes each way. By deceleration the laser link will be a courtesy. I've already moved the daily ops packet to batch transmission. Live oversight from Geneva is functionally over as of this week. What they'll have is history."
Christina watched the amber ribbon pulse. Two months ago the link had answered in seconds, and the ISO duty officers in Geneva had been a presence in the bridge, a third voice in every shift handover. Now their replies arrived with a gap, like hearing through a closed door.
"Has the crew noticed?" she asked.
"They notice," Amy said. "The galley log shows conversation dropping off around the link announcements. People stop talking when the listener takes longer to answer. Serenay asked me yesterday, straight out, how long before Geneva can't reach us at all."
"What did you tell her?"
"That they never truly reach us. That the link is a leash we agreed to wear." Amy closed the curve. "The crew is working out that the leash has gotten very long and very thin, and that the thing on the other end can't correct them in real time. Some of them find that freeing. Some of them find it terrifying."
"Both are correct," Blake said.
Christina heard the sound of boots on the riser and turned. Annabelle Wallis came down onto the bridge deck with a slate under her arm, blonde bun immaculate, medical trim catching the blue console light. She did not look at the camera nodes. Christina had noticed that months ago; the CMO had a talent for looking at a lens without acknowledging it.
"Monthly biometric review," Annabelle said. "You asked for it unvarnished, so I'll give it unvarnished. Everything I say next is already on its way to Geneva in the formal packet, so none of it is a secret. It's only a secret from the crew until the packet lands."
"Understood," Christina said.
Annabelle keyed her slate and the crew's composite health profile bloomed on the medical display: twenty-two silhouettes, each tagged amber, green, or a single worrying red.
"The green column is holding. Fitness, nutrition, injury rates, all excellent. This is the healthiest crew I have ever served with, physically." She tapped the amber band. "Here is the friction. Sleep disruption in nineteen of twenty-two. Not insomnia exactly. Fragmented sleep, shallow architecture, frequent waking between 0300 and 0500. Cortisol baselines elevated across the board, worst in the married cohort and worst of all in the engineering section, where Serenay's people live inside the drive noise and the radiation watch rotations."
"And the cause?" Blake asked.
"You know the cause. I charted it as two variables because the data demands it, but honestly it's one variable wearing two faces." Annabelle's voice stayed level, clinical, almost gentle. "Variable one is separation. The lag compounds it. A crew member can send love to her husband and the answer arrives after eight minutes, and every day the answer arrives later, and the animal brain reads that as the attachment receding at a measurable rate. That does things to cortisol that I can graph and cannot medicate."
She paused. On the bridge overhead, one of the white LEDs ticked through its maintenance sweep.
"Variable two is us," Annabelle said. "Twenty-four hours of optical surveillance under the uniform mandate. I engineered that constraint and I still defend it. It is also, biometrically, a chronic low-grade stressor that never resolves, because there is no such thing as getting used to being watched. The nervous system adapts to noise, to g-loads, to confinement. It does not fully adapt to a witness. Nineteen women are sleeping badly because a small white eye is on them while they sleep, and they all know where the feed goes."
Blake was quiet for a moment. "You're asking for a mitigation."
"I'm reporting. Mitigation is above my authority. But I'll put my recommendation in writing tonight, and it will say that the medical bay sleep pods and the hydroponics bay should get physiological exemptions review, if any exemption is ever going to exist." Annabelle met Christina's eyes. "I am not optimistic. I'm thorough."
"Thorough is what I pay you for," Christina said. "Send the packet. Flag it for my read before Geneva's."
Annabelle nodded once, gathered her slate, and climbed back up the riser. At the top she stopped, half-turned. "Captain. One thing off the record, meaning only that it won't survive into the packet." She waited for Christina's nod. "Daniel sent another message. It came through the crew mail relay an hour ago. I know because he's my patient's husband and the mail system routes family-flagged traffic through medical for the morale log. It's in her queue."
"It's in her queue," Christina said evenly. "Then it's hers."
"Yes, ma'am." Annabelle went up and out, and the bridge hatch sighed shut behind her.
Christina stood looking at the shrinking sun on the forward display and did not think about the message in her queue. She thought about it the way she thought about a fault light: acknowledged, deferred, logged.
Blake touched her elbow, light, two fingers. "Later," Blake said quietly, and it wasn't a question and didn't need an answer.
"Bridge to security," Christina said instead, louder, and the overhead picked it up clean for the lens.
Katheryn Winnick's voice came back immediately, flat and cold as a blade laid on ice. "Winnick here."
"Status walk. Report."
"Two items, Captain. One, section twelve medical annex is still flagged for my walk-through and I haven't forgotten. Two, and this is the live one." A pause; Christina pictured her down on the sub-deck access, braided crown, assault boots planted wide on the grating. "Sub-deck four, secondary radiation shielding trunk. My overnight sensors logged a telemetry flicker in the lead-bismuth baffle monitoring array. Three seconds of dead feed at 0217, then clean. The trunk runs magnetic interference from the drive conduits on both sides. My techs can't confirm whether the flicker was sensor-side or real, because that trunk is the only place on this ship where the cameras and the telemetry both go half-blind."
"The ISO grid too?" Blake asked.
"Everything. The magnetic flux eats the signal. During any physical inspection inside that trunk we are functionally dark, no feed, no link, nothing. Millie in sensor tech calls it the blind slot. It's about nine meters of ship."
Christina felt the silence on the bridge change texture. Amy had gone still at her console. Yeonwoo's hands hovered over the chart. Nobody said the obvious thing, which was that a blind slot on a fully surveilled ship was a room no one had entered yet.
"Then it gets inspected by hand," Christina said. "Serenay and I will walk the trunk personally, with a structural diagnostic team. XO, CMO, you're with us. Commander, you set the exclusion perimeter and log entry and exit times down to the second. If we're going to be dark for nine meters, Geneva will know exactly how long and exactly who."
"Copy that," Katheryn said. "I'll walk the hull integrity points with Anya en route and meet you at the trunk seal."
"Six hours," Blake said. "Mid-hull deck walk first. Full pass, bow to stern, every compartment, every face. If the crew is sleeping badly, I want to see it in their eyes before I read it on a chart."
Christina drained the coffee and set the mug in the pedestal clamp. The white LEDs ticked overhead, and the amber telemetry ribbon pulsed toward a planet that would hear their report eight minutes late.
"Navigation," she said, "keep the baseline honest. Command has a ship to walk."
The mid-hull deck received them the way it received everyone, with a corridor three meters wide and a white node overhead every four meters, its LED steady as a held breath. Christina took point at an even pace, and Blake fell in a half-step behind her left shoulder, and the geometry of it was understood by every woman they passed. Command did not walk separately. Command walked as a wall.
The corridor smell changed at the fourth intersection, dry composite giving way to something wet and green and ancient. Life Support. The hydroponics bay opened around them in tiers of ultraviolet light, four closed-loop biomes stacked like cathedral shelves, each rack a dense curtain of dwarf wheat, soy climbers, and algae panels sweating oxygen into the ship. The humidity hit Christina's face like a warm cloth. It was the one compartment on Proxima I that smelled of Earth.
Two hydroponics specialists were working the second biome, sealed sleeves in the nutrient troughs. Karen Gillan looked up first, tall and flushed in the grow-light, and the younger of the pair, Shailene Woodley, kept her hands in the trough a moment longer, as if finishing a thought before surfacing for rank.
"Captain on deck," Karen said, and both stood, dripping nutrient solution onto the grating.
"As you were," Christina said. "Report on biome two."
"Oxygen yield's three percent over projection, ma'am." Karen wiped her forearms on a cloth. "Root mats are denser than the models said they'd be at 0.12G. We're hand-thinning them twice a day."
"They grow like they know we need them," Shailene said, and then seemed to hear herself under the camera node and added, "Biologically speaking, ma'am."
"Biologically speaking is the only way they grow," Christina said, and saw the two women's shoulders come down a centimeter. That was the arithmetic of the grid. Every sentence had to land somewhere between candor and compliance, and the crew was exhausted from doing the arithmetic.
Blake crouched at the trough edge and studied the root mats. "Sleep pods in here yet? Medical flagged this compartment."
"Not yet," Karen said. "There's a requisition."
"There will be a review of the requisition." Blake straightened. "Log it as prioritized. XO's authority."
"Yes, ma'am." Something moved through the two specialists' faces that was not quite a smile. They looked at each other, brief, wordless, the way people do when a small unfairness shifts a centimeter toward fair.
Christina walked the tier line and let the wet green air work on her. The amber glow of main plasma conduits ran along the aft bulkhead, a low warm pulse under the ultraviolet racks, and for a moment the compartment was the most beautiful thing on the ship. She did not say so. The lenses did not need that.
At the aft end of the bay was an observer corner, a reinforced viewport alcove with two fixed seats built into the hull rib, angled to watch the biomes. It sat just past the coverage arc of the nearest node; she had studied the grid overlay in month one and knew every such seam on the ship the way a prisoner knows a yard. She took the seat and Blake took the other without asking, and they sat in the wet green light with the ship's heartbeat in the deck.
"Eight minutes is already unbearable," Blake said quietly. "I watched it this morning. You queued a reply to the packet, and you didn't send it, and then you did, and you sat there."
"I did."
"He'll answer before the end of your shift now. In a month he'll answer tomorrow. In a year, you'll be writing letters to a man who reads them a week after you've forgotten what you meant by half the sentences."
"Daniel is precise," Christina said. "He'll have kept every one. He'll reread them until they arrive." She watched a wheat curtain shiver in the ventilation flow. "Twelve years, and I negotiated a waiver that put four light-years and six years of burn between us. Some nights I run the sum and can't make it come out to anything."
"And some nights?"
"Some nights it comes out to this ship." She said it plainly, for no one but Blake, and even so she kept her voice at command pitch, because the habit of being overheard was in her bones now. "You have no one in the queue. Does the lag frighten you or free you?"
Blake was quiet long enough that the ventilator filled the silence. "Both. Which I believe is the official medical answer." She turned her head. "But I'll tell you what actually keeps me up at 0400, Captain. It's not the lag. It's the nodes. Nineteen women sleeping badly because of them, and I approve their requisitions one camera-neutral sentence at a time."
"And in the blind slot, none of that exists."
"That's what worries me," Blake said. "And what, God help me, interests me."
Christina heard it and did not answer, and the two of them sat there for ten more seconds of green silence, which was more privacy than the ship had given either of them in two months. Then Christina rose, and Blake rose with her, and they went out through the humid air with their posture reassembled, two statues in charcoal-grey, and the node caught them clean at the hatch.
The engineering conduits forward of hydroponics ran hot and amber. Serenay Sarıkaya was already there, high ponytail, utility harness cinched tight, overseeing two of her specialists at a thermal check junction. One of them, Mackenzie Foy, had a heat gun and a tablet and the narrowed eyes of someone proving a number. The other, Reina Hardesty, had a panel off the wall and was working inside it with her sleeves rolled.
"Captain. XO." Serenay did not stop working; Serenay supervised by doing. "Mackenzie, say it again for command."
"Trunk-side baffle boundary is running half a degree warmer than the flux model predicts," Mackenzie said. "I've re-run it four times. It's small. It's real."
"Sensors or structure," Blake said.
"That's what the walk-in is for," Serenay said. "The trunk baffle monitoring array feeds through a conduit that sits inside the magnetic flux envelope. Inside that trunk, the flux eats low-band signal. Telemetry, cameras, everything half-blind for nine meters. My people won't go in without a structural walk and medical standing by on absorbed dose, and Annabelle agrees, which should alarm us all."
"Quote me accurately," said a voice behind them, "and it will be."
Annabelle had come down the ladder with a med telemetry case and a dosimeter belt, bun immaculate, silver medical trim catching the amber light. She held out the belt to Christina without ceremony. "Full rad belts for everyone entering. Radiation exposure tolerances in that trunk are my numbers, Captain, not engineering's, and I will pull anyone who touches my ceiling. Chief Engineer and I have fought about this politely for months. In there, I win."
"She does," Serenay said. "I've made my peace with the annexation." But her jaw was set, and Christina read the tension under it: Serenay's ship, Serenay's trunk, and a medical officer holding veto power over her engineers. The friction between those two was a live wire, and Christina let it stay live. Both of them were right, and the ship ran on the argument.
"Then we go in on Annabelle's terms," Christina said, and buckled the belt. It sat heavy against her hips, an unfamiliar weight, the weight of a compartment that could hurt them in ways the rest of the ship could not.
They dropped down the conduit ladder to sub-deck four in single file, Serenay first, Christina last but for Blake, the titanium rungs cold through their gloves. The sub-deck was narrower, louder, the drive noise a physical pressure in the skull. And there, at the reinforced hatch of the shielding trunk, stood Katheryn Winnick with Anya Taylor-Joy.
Katheryn had already set the space: exclusion tape across the junction, a portable logger mounted on the hull, her assault boots planted wide, braided crown tight as armor. Anya stood at her shoulder with a breach lamp slung cross-body, watching the dark of the trunk seal the way other people watched a stranger.
"Perimeter is set," Katheryn said. "No one past the tape but the four authorized. Anya has overwatch at the seal with a hardline comm to the logger. The hardline survives the flux. Anything goes wrong in there, we hear it. Anything goes quiet in there," her eyes moved over the four of them, "we come in after you whether it's smart or not."
"Noted," Blake said.
"Captain." Katheryn keyed the logger. "I'm logging entry timestamp for Geneva's delayed record, per your order. Time now is 1147 ship. Party of five, Hendricks, Lively, Sarıkaya, Wallis, Winnick. Expected duration, forty minutes. Exit logged to the second." She looked up. "Whatever happens in there, Earth will have it down to the second, eight minutes late."
"The honest record," Christina said. "Log it."
The heavy pressure seal took two hands. Christina set her grip on the wheel and stopped, one breath, looking at the dark seam where the door would open. Nine meters of lead-bismuth baffle, amber-lit at the margins, dead to every eye on the ship and every eye in Geneva. Somewhere behind her, a white node watched the back of her neck. Somewhere ahead, nothing watched at all.
She turned the wheel. The seal cracked with a sound like a held breath releasing, and the heavy door swung inward on darkness that no lens had ever entered.
The darkness had a texture. That was the first thing Christina felt, standing on the trunk threshold with her inspection lamp off: a pressure, like the space had been waiting two months to be seen by human eyes instead of silicon ones.
"Seal integrity confirmed," Serenay said behind her, wrist-deck strobing green against the open hatch. "Ninety-eight point four percent saturation on the flux envelope. We're officially dark, ladies."
Christina thumbed her lamp on. The beam cut a cone through the narrow conduit and fell against the first lead-bismuth baffle, a dull grey wall of laminated metal that filled the trunk from floor to ceiling except for a crawl gap a meter wide. The light went nine meters and died against the far seal.
No white nodes. No LED sweep. For the first time since the Assembly Platform, there was no lens in her peripheral vision, no small patient eye recording the angle of her shoulders. Her body registered the absence the way a hand registers a released grip.
"Close it," she said. "We're not inspecting with the sub-deck noise bleeding in."
Blake swung the heavy door shut and spun the wheel until the dogs seated with a deep thunk. The sound changed instantly. Cut off from the sub-deck, the main drive stacks came up through the floor plates and the structural ribbing, a hum so low it lived in the sternum rather than the ear, bone-deep, tidal. It was the same hum that had faded into furniture everywhere else on the ship. In here, walled in by half a ton of shielding metal per meter, it was the whole world.
Annabelle clipped her dosimeter belt to a baffle anchor stud and swept the trunk with her own lamp. "Everyone confirm belt readouts on my mark. This metal should be drinking every rem the stacks throw at us. If any of you see a number climb, you say the word and we are out of this tube before you finish saying it."
"Copy," Blake said.
"Copy," Serenay said. "Though I'd like it noted that my drive stacks are behaving themselves."
"Your drive stacks have never once behaved. They've merely been threatened competently."
There it was again, that live wire between them, and Christina watched it settle into work rather than argument. The two women moved to the first baffle junction with their heads close, Serenay's fingers tracing the laminated seam while Annabelle held the lamp and read the thermal overlay on her wrist-deck.
Christina took the portside lane and walked the crawl gap. The trunk was barely wide enough for two, and Blake came in behind her, close enough that their packs brushed when one of them turned. They worked the inspection in a rhythm neither had to negotiate: Christina's lamp high on the baffle face, Blake's low, checking weld beads and anchor torque at the deck plates. Twice their hands arrived at the same stud and twice they resolved it without words, one yielding, one claiming, the geometry sorting itself the way command geometry always sorted.
It was on the third baffle that Christina realized she had not composed her face in an hour. Every expression she had worn for two months had been a document, drafted for the grid. Here her face was hers again, and she did not know what it was doing. She suspected it was tired.
"Captain." Blake's voice had dropped below the drive hum, pitched for a meter of air and nothing else. "Look at the far seal."
Christina raised her lamp. At the trunk's end, the ninth baffle met the far pressure seal, and behind them the amber feed lights bled through a sensor port, two thin orange lines glowing in the dark like embers in a cave. Nine meters of ship that no one on Earth could see, lit by firelight.
"Millie was right to name it," Blake said. "It's not a blind spot. Blind spots are accidents. This is a room."
"Careful," Christina said, but she said it low, and she did not mean it as a warning. She meant it as an agreement she hadn't decided to make yet.
"Readings stable," Annabelle called from the fourth junction. She had her wrist-deck pressed to the baffle skin, and Serenay was crouched at the thermal sensor housing with a calibration probe. "Surface temp nominal, absorbed dose at my floor and comfortably below. The metal is doing exactly what I said it would do."
"For once the medical numbers and the flux model agree," Serenay said, not looking up. "Which brings us to the anomaly. Mackenzie's half a degree." She lifted the sensor cover and shone her lamp into the housing. "Here. Look at the mount."
Christina moved forward, and the trunk compressed all four of them into the junction, shoulder to shoulder around the open sensor housing, breath fogging faintly in the cooled air that bled from the baffle seam. Inside the housing, the thermocouple's mounting bracket had worked loose by less than a millimeter of travel. The sensor sat a hair off its calibration seat, reading the residual heat of its own housing instead of the baffle face.
"A sensor lying to us by half a degree," Serenay said. "Quarter turn on the bracket screw and it tells the truth again."
"Three seconds of dead telemetry at 0217," Annabelle said. "Explain that with your loose screw."
"The flux envelope flexes with stack load. Load varies on the rotation cycle. At 0217 the signal-to-noise fell below the demodulation floor for three seconds. My array's retry handshake is logged; it's in the flicker report, item four." Serenay said it patiently, the patience of a woman who had explained this to a thermal gun four times already.
"So the ship is intact."
"The ship is intact. The shield is intact. One sensor was cold, and now it won't be." She took out the driver, set the bit, and turned the screw a quarter. The readout on her wrist-deck stepped down half a degree and settled. "There. Truth restored."
"Confirm it," Annabelle said.
"Annabelle."
"Confirm it. You taught me that on the drydock tour. Never accept your own calibration; you'll only believe what you hoped."
Serenay looked at her for a moment, and something in her jaw eased. She re-seated the probe, ran the sweep again, and turned the wrist-deck so Annabelle could read it herself. "Confirmed. Within two hundredths."
"Then we agree," Annabelle said. "The hull and shielding are one hundred percent structurally sound."
"Remarkable," Serenay said, packing the driver. "Second time this month."
"I keep count too."
Christina watched the two of them close the sensor housing together, four hands on one panel, and understood that this was what the trunk was for. Not the baffle. Not the sensor. This. Two rivals forced into a meter of shared dark until the argument wore down to the mutual respect inside it. The ship ran on this too.
She turned back down the crawl gap, and Blake fell in beside her, and for nine meters there was nowhere else to put the silence except between them.
"Two months," Blake said quietly. "Two months of composing my face, and in here I caught myself frowning at a bulkhead like a person. I'd forgotten what that costs. Performing sanity for a lens eight minutes from being able to comment."
"I know."
"Do you?" Blake looked at her in the lamplight, and the ice-blue eyes were unreadable and very close. "Because I've been watching you perform availability for a husband who answers slower every day, and performing command for a crew that watches you watch the lens, and performing calm for me. In here you're only tired. It's the first honest face I've seen on you since we cast off."
Christina stopped walking. The drive hum filled her chest. "Careful," she said again, and this time it was a warning, and she heard that it was also an invitation.
"Noted, Captain." Blake didn't move. Neither did she. Two women and one meter of lead-shielded dark, and the closest thing to privacy the human species had left, and they stood in it for three full seconds longer than the inspection required.
"Command," Serenay's voice came down the trunk, dry as the laminate. "For the record, the four of us are about to walk out of the only nine meters in the fleet that belong to us and not to Geneva. I propose we all decide, silently, individually, and forever, what that was worth."
Annabelle said nothing. Blake said nothing. Christina looked back up the crawl gap at the two of them, at the engineer and the doctor standing in the ember light, and understood that the proposal had already been ratified before it was spoken. The blind slot was theirs. Whatever it held, however small, it was the crew's, and no packet would ever carry it.
"Nothing happened in this trunk," Christina said. "That is the operational finding. Log it the way you'd log it to Geneva, and keep the rest where it lives."
"Silently, individually, and forever," Annabelle said.
They finished the walk. At the far seal Serenay checked the baffle anchors one last time and called the trunk green, and the four of them gathered at the hatch wheel. Christina put her hand on it and paused, one breath, the same as entering, and felt all three of them pause with her, a shared hesitation none of them named.
Blake spun the wheel. The seal cracked, and the sub-deck noise and the white light of the work bay poured in, and the first thing Christina saw was Katheryn Winnick's face turning toward them from the exclusion tape, steel-blue eyes sweeping each of them once, fast, professional, missing nothing.
"Exit timestamp," Katheryn said, keying the logger. "1159 ship. Duration twelve minutes. Party of five, all ambulatory." She looked at Christina, and behind the flat tactical calm there was one question, asked and answered in a fraction of a second. "Telemetry flicker?"
"Sensor calibration error," Christina said, at command pitch, for the logger and the lens and the packet that would land in Geneva eight minutes late. "Corrected. Shielding integrity one hundred percent."
Katheryn nodded once and pulled the tape down. Overhead, the nearest white node ticked through its sweep and settled on them, patient as teeth, and Christina walked back into its gaze with her face composed and something new folded and hidden behind it, small as a quarter turn of a screw.
The transition back into the grid was physical. Christina felt it in her shoulders first, the way they set themselves as the work bay light flattened them, the way her stride lengthened into the pace the lenses knew. Nine meters of honest dark behind her, and already her face was a document again.
Anya coiled the hardline comm in quick loops, breach lamp dimmed, and said nothing. She had watched them come out of that hatch, and whatever she had read in five faces she had folded away behind the same professional stillness she wore everywhere. Katheryn broke down the logger with two hands and a key, lifted the storage module, and slotted it into her chest rig.
"Transmitting the diagnostic package to the Earth queue now, Captain," she said, thumbing her wrist-deck. "Full timestamps, full telemetry, my sensor log annexed. Shielding integrity one hundred percent. Correction logged as calibration error, sensor housing four, bracket screw, quarter turn."
"Word for word," Christina said.
"Yes, ma'am." Katheryn's eyes came up once, held hers for a beat too short to be insubordinate and too long to be nothing. "For what it's worth, twelve minutes is a clean inspection. Shortest trunk walk I've logged."
"Efficient crew," Christina said, and the phrase sat between them like a coin on a table. Katheryn picked it up.
"Dismissed, then. Anya, tape and stanchions."
They walked away up the junction, boots precise, and Christina watched them go with the understanding that the security chief had just told her she knew. Not what. Only that something had been worth twelve minutes instead of forty. Katheryn lived inside the same grid the rest of them did. She read exits the way doctors read faces.
"That was a message," Blake said quietly.
"That was a receipt," Christina said. "She'll keep it."
They climbed the conduit ladder in silence, amber light sliding over them, and the sub-deck noise fell away behind them rung by rung. By the third rung Christina had her voice back. By the sixth she had her face. By the top she was entirely the Captain again, and Blake was entirely the XO, and the blind slot was a folded thing both of them carried in the same pocket.
The bridge at evening shift received them with its usual immaculate order. Yeonwoo stood the astrometrics console, low braid neat, hands moving through the burn-correction sequence with the economy of a pianist. Amy had the link console, wrist-deck synced, the amber telemetry ribbon arcing down the screen toward a planet that had just become eight minutes away in full.
"Evening transition, Captain," Yeonwoo reported. "Baseline burn nominal at zero point one two G. Vector corrections are inside tolerance. Proxima Centauri sits four point two light-years out on the board, and we are aimed exactly where the models say it will be in six years."
"And the link?"
Amy turned. "Official as of 1712 ship time, Captain. One-way light delay is four minutes and six seconds. Round trip, eight minutes and change, and climbing eleven seconds a day. Geneva is now a correspondence, not a presence." She paused, and her voice did something dry at the edge. "I've updated the crew bulletin. The wording is 'enhanced operational autonomy.' The crew will read the number and understand the words underneath."
"They will," Blake said. "Read the shift-change log aloud. I want it on record for the delayed auditors."
Amy read it. Yeonwoo confirmed the burn. The white nodes overhead ticked and settled, and the bridge did what it always did, which was run flawlessly under a gaze that could not answer for eight minutes. Christina stood the pedestal and watched it and thought: this is what they will see. This is what the packet will carry. The flawless surface, the women moving like clockwork, the nothing to see.
Except nine meters of sub-deck that no packet would ever carry.
"Shift change complete," Yeonwoo said at 1830. "Evening watch is Yeonwoo and Acker, per rotation."
"Then the command deck is yours," Christina told them. "XO, walk with me."
Blake fell in beside her without a word, and the two of them went down the riser and out through the corridor, past the nodes, past the hum. Officer country was quieter. The berths ran in a row along the port side, each door a slate of name and division, and the white LED outside every fourth door watched the corridor like a sentry in a landscape of doors. Christina stopped at her own.
She had not opened the queue.
She had known that since morning. The message had sat in her slate all through the hull walk and the drill of command and the twelve minutes of dark, a fault light she could not bring herself to extinguish. Now she stood in front of the door with Blake beside her, and the corridor was empty, and the node was fifteen meters back and had a clear line.
"Inside," she said. "Off the corridor."
The berth was small and exactly arranged. Christina shut the door and sat on the bunk edge and opened the slate, and Blake leaned against the bulkhead with her arms crossed and did not pretend to be anywhere else.
Daniel's message was long. He had always written long.
The first third was logistics. The house, the lease transfer, the way the maple in the courtyard had come in early that year. He had signed the final relocation waiver; he wanted her to know it had been signed gladly, without the lawyer in the room. The second third was harder. He wrote about the lag. He had run the numbers himself; he was an engineer, of course he had run the numbers. By the end of year one he would be writing to a woman who heard him the next day. By the end of the transit he would be writing to a woman who had been four years dying when his sentences arrived, and he had decided, he wrote, to think of it not as distance but as patience. Every letter an act of patience, on both sides, for six years.
The last third was short. He wrote that he was proud of her in a way that had outgrown their marriage and needed somewhere to go, so it was coming to her in text, over eight minutes, forever. He wrote that he hoped she had found her people. He wrote: take care of them, and let them take care of you. You were never good at the second half.
Christina read it twice. The second time her face did what it wanted, and Blake watched it do that, and neither of them said anything until the slate dimmed.
"He let me go," Christina said finally. "Twelve years, and the last thing he does is make the letting go easy. That's the cruelest kindness he knows how to build."
"He ran the numbers."
"He ran the numbers." She set the slate face-down on the blanket. "I ran them too, and mine come out different. Mine say that by turnover I will be more ship than wife, and he knows it, and he wrote anyway, because writing is the only structure he has left that holds me." She looked up at Blake, and the ice-blue eyes held steady. "You asked once whether the lag frightens me or frees me."
"I recall."
"Neither. It clarifies. Eight minutes today, forty in year three, silence by the end. There is a date, out there on the burn curve, when Earth stops being a place and becomes a memory I correspond with. And on the other side of that date there are twenty-one women and a nine-meter trunk and this ship, and I have decided, tonight, in this berth, that they are the sum. Not the remainder. The sum."
Blake unfolded her arms slowly. "Do you want that on record, Captain?"
"You know the answer to that."
"I do." Blake came off the bulkhead and stood over her, close, voice pitched for two people and a closed hatch. "For nothing on record, then. I have no queue. I've understood that since the academy. But I heard his last line. Let them take care of you." A pause. "That includes the XO, whether it's on the org chart or not."
"Noted," Christina said, and heard, in her own voice, the exact tone she had used in the trunk. Careful, meaning an agreement she hadn't decided to make yet, already made.
At 2100 ship time the ship began to go dark.
Night-shift protocol rolled through Proxima I in a wave, compartment by compartment, the main lighting stepping down to amber watch levels and then to soft red rest hues that turned the corridors into embers. The galley logged its last service. The hydroponics specialists dimmed biome two and left biome four on night cycle. Sleep pods whispered closed. Nineteen women lay down under small white eyes that never closed, and their feeds went to Earth in eight minutes, and Earth slept too, six hours behind and shrinking.
On the bridge the lighting eased to deep red, and Yeonwoo took the watch with Amy at the link console, two silhouettes working in low crimson calm. The forward display held the ship's whole future: a cold scatter of instrument stars, and at its center, too faint yet to see, the small red dwarf they were falling toward at a continuous one-tenth of a gravity.
Christina stood on the command riser with her hands loose at her sides. Blake came up the steps and stopped at her left shoulder, half a step back, the standing geometry they had worn into their bones, and for a long minute neither of them spoke. The drive hummed through the deck plates. The burn held.
"He'd like this view," Christina said at last.
"Then it's yours," Blake said. "Both of them can be."
Overhead, the white nodes ticked through their sweep, patient as teeth, and settled on the two of them, and recorded two officers watching the dark between the stars, nothing more. Under that gaze, in the red light, Christina turned her head a degree toward Blake, and Blake did not move away, and the distance between their shoulders stayed exactly as it was: regulation, and known, and no longer empty.
The ship burned on toward Proxima Centauri, and the small folded thing they carried between them stayed folded, silently, individually, forever, or at least until the next nine meters of dark.
