The days leading up to the Ganymede encounter unfolded in a long, watchful calm. The crew moved through their routines with focused care, saving their energy for what lay ahead. A normal shift for Kaius started at the command console with overnight telemetry logs, followed by a systems walk-through with Rook, navigation cross-checks with Seline, and a quick medical sync with Maya. Then came two hours on the exercise equipment, meal prep from the greenhouse, and maintenance rounds—cleaning filters, checking panel torque, calibrating the recyclers—before the final status report to Houston. Breaks were simple: a few minutes floating in the observation module with a pouch of water, or scrolling through old family photos stored on his tablet. Double shifts turned the same cycle into back-to-back loops, with only a short four-hour sleep window in between.
Kaius floated near the command console during one of his breaks. Laura’s voice replayed in his mind, warm but carrying strain: “Emma draws the ship every day, Kai. She keeps asking when you’re coming home. I tell her you’re working hard for all of us.” Then Emma’s uncertain tone: “Daddy? Are you still coming home?” Houston’s reassuring transmission followed, measured and professional: “Odyssey, projections remain nominal. The Ganymede window opens in nine days. Run all pre-encounter checklists and stay in hardened mode. We’re with you every step.”
Rook drifted past, holding a worn deck of cards. “Want in on a game, Commander? I’m losing to myself again.”
Kaius gave a small smile. “Maybe after the next checklist. You keeping busy?”
“Trying to,” Rook said, snapping a card down. “Beats staring at the same bulkhead.”
In the engineering bay, Seline worked with earbuds in, classical piano faintly audible as she tightened a panel that didn’t strictly need it. Maya floated by with a small pouch of fresh cilantro and a few ripe strawberries. “Smell this before the radiation gets worse,” she said softly. “The plants are still holding strong.”
Seline pulled one earbud out and inhaled. “That actually helps. Thanks, Maya. How are the trays holding up?”
“Better than expected.” Maya thought for a moment, tilting her head toward the faint music. “What are you listening to? Is that Chopin?”
Seline gave a tired half-smile. “Yeah. Nocturne in E-flat. Helps me focus when things feel… off.”
Maya looked toward the plants before answering. “My grandmother used to play samba whenever she cooked. I still have some of her old recordings.” A faint smile touched her face before fading again. “There’s one from the seventies I think you might like. It has a kind of stubbornness to it. It always helped her through difficult days. I could send it over, if you want.”
Seline raised an eyebrow, the ghost of genuine curiosity breaking through her usual reserve. “Samba, huh? Didn’t peg you for that.”
Maya looked down for a moment before meeting her eyes again. “It was my grandmother’s thing,” she said simply.
A rattling pump stole an hour from everyone’s day before Rook finally coaxed it back into operation. By afternoon the ship had settled into its familiar hum again. In the greenhouse, Maya was bent over her tablet, jotting down some notes beside the grow trays, when a wave of dizziness made her catch herself on the frame. She looked up to find Seline standing quietly in the doorway. “You’ve lost weight.” It wasn’t a question. Seline’s voice was gentle, almost tentative.
Maya gave a small smile that never reached her eyes. “Have I?”
Seline nodded. “Your face… and your wrists.” She glanced down for a moment before meeting Maya’s eyes again. “I’m sure you must have noticed it.”
“It’s nothing.” The words hung between them. Finally Maya looked back at the rows of green leaves. “It’s just…I’m not very hungry.”
Seline studied her for a long moment, then wrapped her hand softly around Maya’s wrist. “Do you see, Maya? My thumb can touch my fingertips. What’s going on?”
Maya felt cornered. “Seline,” she said, resisting. “We’re in a broken spacecraft heading for a double-slingshot around Jupiter. I think that all of us are feeling the strain.”
“That’s not the whole story.” Sel wrapped a second hand around Maya’s other wrist, and looked her in the eyes.
Maya felt tears well up, not enough to cry, but a heavy wetness that blurred her vision. She inhaled deeply then let out a breath. “I don’t know, Sel. When things feel uncertain…it becomes easier to think that someone else should eat first.”
Seline frowned. “There isn’t anyone else first. We’re all carrying the same mission.”
“I know.”
“But you’re carrying it without enough food.” Maya didn’t answer. After a moment where neither of them knew what to say, Seline reached around and gave Maya a hug. “Please don’t disappear while we’re all watching the planets.”
Maya exhaled deeply then, moved by the concern in Seline’s voice. A faint warmth came to her smile. “I’ll try,” she said quietly. Seline returned the smile, accepting the answer for now, though it clearly wasn’t enough.
Nine days later, while the crew strapped into their stations an hour before reaching Ganymede, Maya lingered in the greenhouse until the last possible moment. Kaius never looked away from the trajectory display. “Sel,” he said, his throat strained with fatigue, “run the Ganymede pass one last time. The full sequence—in plain words.”
Seline’s fingers continued their precise dance across the panel. She brought up the Ganymede playbook on her screen. “In fifty-two minutes, we slam into the moon’s gravitational field, which grabs us and drags Odyssey down toward its surface. The acceleration should be on a par with what we experienced with Mars, and the strain will be just as pronounced.”
“That’s when we’ll find out how much weaker our structural frame is, seven months after that first slingshot,” Kai observed.
“That’s right,” Sel said. “We’ve managed fine floating on a straight line in space, but Ganymede will tear at any weaknesses that we’ve been carrying.”
“Let’s say we make it,” Rook put in. “What comes next?”
Sel’s eyes were still on her screen. “If Odyssey holds together, it should all play out the same as with Mars. Rapid acceleration as the gravitational field pulls us down, and then a precisely timed exit when we’re at maximum velocity and have the correct angle for the Jupiter encounter.”
“So,” Rook laughed, “‘just like Mars,’ except that we’ll be thrown into the gravitational field of a planet that’s a thousand times the size of Earth. I always imagined my first trip here would involve a better hotel.”
“A thousand and three hundred times,” Kai corrected. “And a bit.”
“At the right angle,” Sel interrupted, “that puts us into line for a slingshot that takes Odyssey well beyond acceleration vectors that have ever been tested while also bathing us in radiation fields hitherto uncharted by anyone. The math says we’ll be in that soup for a little more than eighteen hours, and if Odyssey hasn’t been ripped apart, we’ll be thrown out the other side after we’ve swung across the planet’s arc, putting us in a straight line toward an empty spot in space where Earth is calculated to be arriving in a little less than a year.”
“Aiming for the stars,” Rook said.
“The planets,” Kai corrected, “the ever-moving planets.”
“If the radiation doesn’t kill us all it’s going to wreak havoc on our instruments. It’ll chew through the electronics without mercy,” Sel added.
Maya came into the main module at that point, wiping her hands down the front of her coveralls with the sharp living smell of soil still clinging to her. She glanced at the medical readouts before sitting down. “Are the instruments even reliable now? That last radiation spike was nasty. I’ve got the greenhouse shielded, but I’m worried about losing power in the support systems. Are the battery backups ready if secondary power goes out?”
“Backups are solid from yesterday,” Seline answered without hesitation. “The plants might slow down but they will not die, though the navigation array worries me more. One glitch could send the timing straight to hell.”
Kaius rubbed the back of his neck, fingers pressing into the tight knot there. “Double-check everything one last time. Rook, you jump on manual if the computers blink even once. Maya, keep a close eye on crew vitals when the pull gets brutal. We will handle this together as a crew, the way we always have.”
“Speed looks good,” Seline read off steadily. “Radiation climbing as expected, shields holding for now, and the path is staying steady.”
Maya gripped her armrests as the pull from Ganymede increased. The familiar dizziness was back, but this time it brought something harder with it—a memory of her grandmother from twenty years ago: “You always hide in the dirt when things get hard, Maya. Real life is a mess.” She hated how right her grandma still was. The pull started gradually at first, then built as Ganymede’s gravity caught them fully and the ship began its long curving path. The hull made low groans that vibrated through their bones, deeper and more insistent than they had been during the Mars slingshot. For long minutes the moon’s surface slid past with craters sharp and unforgiving in the dim glow. The ship shuddered harder, metal protesting in ways that made the earlier Mars encounter feel almost benign. While every rattle raised the same unspoken question—how much weaker had they become in the seven months since? —each one passed and diminished until the pressure steadied and nothing had broken down. The crew stayed wordless, willing Odyssey to survive this pass.
Sel burst with a sharp, “We’re clear!” and, as one, they let out a held breath and laughed.
“We’ve cleared the main pull from Ganymede,” Rook echoed, letting out a breath he seemed to have been holding. “How bad could Jupiter be?” No one answered, wary of tempting fate.
The moon’s fractured surface drifted away in the windows. Seline let her head fall back against the headrest for a second, eyes closed, a quiet, weary laugh slipping out as she kept one hand steady on the controls. Maya pressed a trembling palm to her chest. “Obrigado, meu Deus,” she whispered, the words slipping out before she could think—the same simple prayer she had heard countless times growing up.
For several long seconds, no one spoke. The only sounds were the ship’s hull creaking as it settled and the soft hiss of the life-support systems. Odyssey had endured, finding exactly the right exit angle. The trajectory held true, and they were still aligned for Jupiter. After weeks of fraying nerves and shrinking margins, a cautious sense of victory stirred among them. It wasn’t loud or certain, but it was real: the first breath of hope they’d allowed themselves in a long time.
Jupiter didn’t approach so much as awaken around them. It swelled across the forward windows until there was no longer any sense of empty space beyond the glass, only a colossal body in slow motion. The cloud bands no longer looked like weather but like immense muscles shifting beneath skin, folding over one another in currents too large for the mind to follow. The Great Red Spot was not a storm so much as an ancient scar that had never finished healing, turning endlessly through flesh older than civilization. Even the light seemed altered here, stretched into strange softness by gravity so immense that it no longer felt as though it merely bent space, but rewrote the way distance itself could be crossed.
Inside Odyssey, they felt Jupiter before they truly saw it. Harness straps pulled differently against their shoulders, and a loose wrench drifted across the cabin, then slowed for no reason any of them could explain. No one spoke. Seline studied her screen for another second before breaking the silence. “We’re inside the interference zone,” she said. “Radiation’s climbing faster than we predicted. The instruments are starting to lose accuracy. Hardened mode is holding… for now.”
Rook lowered his tone. “Overrides are still green. Manual control is responsive. I’ve got burn authority.” He paused, eyes flicking briefly toward Kaius. “Kai, I’m standing by for timing lock.”
Kaius didn’t respond. His eyes remained fixed on the main trajectory display, but the lines no longer looked like clean mathematics. They seemed to shift each time he blinked, refusing to settle into the patterns he had trusted his entire career. A dull pressure had been building behind his eyes for hours—not enough to concern him, only enough to be ignored. Then, without warning, a memory surfaced: his first flight instructor tapping a navigation chart with the back of a pencil. “Trust the numbers. They don’t care what you’re feeling.” The memory stayed with him for a heartbeat before dissolving into the hum of the ship.
Then, without warning, the pressure in his head became absence. His neck loosened and Kai’s head dropped forward, not slowly, as in sleep, but instantly, as though something in him had simply switched off. His body slackened in the harness while his eyes remained open, unfocused, seeing nothing that belonged to the ship or the present moment. Rook noticed first. “Kai?” The question came out uneven. He leaned forward instinctively, as if distance was the problem. “Kai, talk to me. We’re still in burn window.” No answer came. Only the sound of the hull deepening under strain, and the rising whine of engines fighting a gravity field that did not feel natural anymore.
Seline did not stop working, but something in her expression shifted as she ran a fast diagnostic across Kaius’s systems. “Vitals are stable,” she said, but there was an edge underneath it. “Heart rate is normal. No seizure activity. No neural spike. He’s not in a collapse state… he’s in a non-responsive plateau.”
Maya was already unstrapping, bracing herself against the increasing force as she moved. She reached Kaius and checked his carotid artery, then his pupils, then the medical display, moving in precise resistance to panic. “Pulse is normal,” she confirmed. “Respiration normal. Pupils reactive but unfocused.” She leaned closer. “Kai. If you can hear me, squeeze my hand.” There was nothing. And for the first time, Maya’s calm did not feel like control—it felt like something holding back collapse. A memory returned to her, insisting: Maya as a kid, in a hospital corridor that smelled too clean, listening to a doctor speak in a tone that meant decisions had already been made. She blinked it away and pressed two fingers more firmly to Kai’s wrist, willing her presence to anchor him.
Rook’s jaw tightened. “Not now,” he whispered, but it was less denial than disbelief. “Sel, I need the burn sequence. We’re inside the tolerance window.”
Seline faltered. It was small. Almost invisible. Kai’s voice had always been the trigger. Now she had to replace his timing with her own, under full Jupiter interference. Her fingers resumed, faster than before. Something in her posture changed, like a person who must compensate for unstable ground. “Seventy-three seconds to the correction point,” she said. “I’m reconstructing the vector manually.” A long beat. “Rook, you cannot chase lag here. You will overcorrect if you anticipate a delay.”
“I know how to fly,” Rook snapped; then he corrected himself mid-breath as the ship shuddered harder. “Just give me the timing. I need to keep a margin for radiation drift at this point.”
“I’m already accounting for it,” Seline insisted, unable to soften her tone. The edge was not directed at anyone, only at the absence that was sitting in Kai’s seat. “Mark in six seconds. Four. Two. Mark.” Rook fired the engines. The ship moved in several directions at once, as it resisted being torn apart. Every plate in Odyssey’s frame answered the burn with strain, orchestrating an entirely new sound, the metal remembering all of its limits. Jupiter’s radiation surged harder now, and the navigation display began to distort in waves, not breaking but warping, as if reality was struggling to stay aligned. Inside the cabin, pressure built not just in their bodies but in their perceptions: sounds felt slightly delayed; light was both too bright and too dim; breathing seemed to require negotiation.
Rook adjusted continuously, but his control inputs were no longer smooth. “I’m getting lag spikes on port thrusters,” he muttered. “That shouldn’t be happening at this range.” Almost under his breath, “Come on…come on…”
Seline’s mind moved fast-forward in loops, reinterpreting constantly shifting data. “Starboard correction drifting again—compensate two degrees. No—hold—three degrees. Stabilize before input, don’t react to noise.” She meant it for herself, and was surprised to hear she’d spoken it out loud. Sel forced herself to stay composed. “If we chase every fluctuation we will lose the burn profile entirely.”
Maya stayed beside Kaius, one hand on his shoulder, not just to steady him physically but because letting go felt like acknowledging something irreversible. For the first time since launch, Maya wanted someone else to tell her the next step. She wanted, just for a moment, to be the person who was allowed to be afraid. “Still stable,” she kept repeating. Then, when she finally let the thought escape, “You’re supposed to be the one who doesn’t leave first.” The burn stretched longer than it should have. Jupiter stopped feeling like a relay point and started feeling like a test with no rules. Radiation intensified in bursts, and for brief moments the instruments showed things that had no business being there—an old Apollo photograph of Earth rising above the Moon, gone again before anyone could question it.
“I know,” Seline said, and for the first time something in her words gave way. Not into fear exactly, but into something older. Her fingers hovered over a control input. And then it happened. Not loudly, nor even visibly, more like a fracture in attention—for half a second, Seline was no longer on the ship. She was small again. Smoke filled a room that should have been safe. Heat pressed against walls that were supposed to protect her. Somewhere in the distance, she heard her parents calling her name, but the sound was low and unreachable. She remembered standing frozen on the second floor of their burning house, unable to move toward them, not because she didn’t want to, but because her body refused to understand what “help” meant. That same paralysis rose in her chest now, sudden and suffocating, as Jupiter’s massive gravitational forces seemed to draw the past into the present.
“Seline!” Rook’s voice snapped through it.
She blinked hard, breath catching, hands trembling once before forcing themselves back into motion. “I’m here,” she said immediately, too fast. “I’m here. Adjust vector—two point six degrees starboard. Now.” Rook didn’t question it. He just obeyed. The burn surged again, and for a moment it felt wrong—too strong, too angled, too aggressive. The ship jerked violently as if it had been pushed past what physics considered acceptable. Alarms flared, then went quiet, then flared again.
“What did you just do?” Rook demanded.
“Something we didn’t plan for,” Seline said tightly. “Hold it. I think it’s right. Don’t correct it yet.”
“This feels like it’s breaking us,” he said.
“It might be,” she answered. “But the break is the only thing that will get us out.” And then Jupiter changed. Not visually, but in the force it exerted, the way its gravity felt, as if the pull that had been tightening around them suddenly reached a threshold and began to run in the opposite direction. Instead of being dragged down, Odyssey felt a sudden, violent release—as if the threshold of being caught was a revolving doorway that, on entering, flung them outward. For a few seconds, no one spoke. Then the forward display began to stabilize and the distortion eased. The radiation spikes flattened into something the systems could actually interpret, and little by little—almost disbelievingly—Jupiter began to fall away behind them.
Rook let out a sound that was halfway between a laugh and weeping. “That wasn’t… that’s not the planned curve.”
Seline stared at the numbers for a long moment, then murmured, almost to herself, “no, it’s not. But it matches. It actually matches.” Maya did not speak. She was still holding Kai’s shoulder, more content with silence than with any words she could conceive of. Finally, very quietly, Rook said, “We should not have survived that, Sel.”
“No,” Seline said simply. “Did we?” And for a long moment, no one answered her question. Jupiter kept shrinking in the rear windows and for several long beats the module was quiet except their own ragged breathing. Maya closed her eyes and let her shoulders finally drop. The crew sat still, hearts racing, letting the adrenaline surge through them. Odyssey had held. The double slingshot was complete. After all of that, they were pointed toward home.
Rook rubbed his face with both hands and let out a shaky laugh. “Well, whatever it was, we actually did it. And without him at the controls. I thought for sure we were going to screw the timing on that last correction.”
Seline leaned back in her chair, a fierce, exhausted smile breaking across her face. “Your adjustments were solid, Rook. A little heavy on the port side, but you caught it.” She paused, then added more quietly, “I wasn’t sure I was feeding you the right numbers fast enough. Kai always made it look easy.”
Maya looked at each of them, and then at both of them. “Thank you. We’re alive.”
The crew unstrapped and they carefully moved Kaius to the observation module. Maya set up a stable line for fluids and nutrients, checking his vitals every few minutes. His eyes remained open but unfocused, his breathing slow and even. Everything stayed within normal range. He was simply…absent.
For the next few days, nothing happened. No alarms. No fresh failures. No one had to strap into their seats expecting the ship to come apart. It almost felt normal again. One evening, Rook drifted into the galley carrying a pouch of tea. “I keep replaying that last correction,” he looked down at his hands. “I snapped at you, Sel. Sorry.”
Seline looked up from her tablet. “I hesitated. I know I did. I kept waiting for Kai to wake up and confirm the vector.”
Maya spoke as she drifted near them. “You both carried more than your own roles. That kind of pressure shows the cracks. The important thing is you kept the ship on course.” She gave them a small, steady smile. “We’re still a crew. Even if we’ve changed our roles.”
Rook gave a thoughtful nod. “Yeah. Thanks, Maya. I don’t know how you stay so level through all this.”
Sel shook her head and said nothing, catching Maya’s eye. “Practice,” Maya said simply.
Seline spent two days in the comms bay with the panels off and came out with the answer, and she gave it to them in the galley in the flattest voice she had. “The exciter is gone and the amplifier is gone. Both of them, on the same pass, while we were inside of Jupiter’s magnetic belts. There is no spare for either one on board this ship, and there is nothing in the fabricator’s library that will make one.” She put her tablet face down on the table, which was how they knew she had finished checking. “We can receive. We cannot transmit. That is the whole of it, and it is not going to improve.”
Rook said, “Say the part you’re not saying.”
“Houston will go on talking to us. They have four antennas and a procedure and they will not stop. We will hear every word.” She looked at each of them in turn. “They will not hear anything from us. Not a word, not a tone, not a carrier. As far as Earth is concerned, this ship went quiet in the eleventh hour of the Jupiter pass and has not said anything since.”
They kept sending anyway. Seline wrote the log and the status every day and put it out on the dead transmitter, because it cost nothing but the writing, and because a day would come when somebody would ask what had happened out here, and she intended to have the answer written down. In the months that followed, Houston’s traffic kept arriving, and its tone changed. The routine queries became requests to acknowledge. The requests became instructions to attempt a response in any mode, on any schedule. Then came the medical traffic about Kaius, which told them something they had not known: on Earth, somebody had decided that the silence was a crew problem and not a hardware problem.
As the weeks passed, they reconstructed a version of normal life. Comms with Houston were restored, but only one way, as if their instruments were catching fragments of messages sent long ago. Nothing they tried sending received any coherent reply. Rook’s banter returned, gentler now. Seline spent long hours verifying their trajectory, but she began including Rook in the checks instead of working alone. Kaius remained in the observation module, motionless except for the steady signs of life shown on the monitors. Maya continued to watch over him, carefully managing his condition. He was stable, but his absence followed them through every day, a reminder of how close they had come to losing him. Then the strange signals began again. One transmission from Laura came through, and the words made no sense. She spoke about Kai’s condition, about conversations with doctors that the crew had never had with Houston. “I’m trying to stay strong for Emma,” Laura said, struggling to keep herself together. “But the doctors keep asking me questions I don’t have answers for.”
Seline played it twice, confused. “They don’t know about Kai’s blackout. How could she be answering something we didn’t report?”
Rook frowned. “They don’t make sense. The comms must be getting crossed somewhere. Radiation scrambling the packets?” Instruments insisted their trajectory was correct, pointed toward the inner system. Yet outside the windows the starfield shifted in ways that felt impossible. Once, Rook swore he saw a distant object that reflected light like a spacecraft before it vanished from sensors. Seline caught a radio fragment that sounded like Houston giving coordinates placing them far outside their calculated path. The doubts crept in, like a shadow lengthening across the module. They believed they had succeeded at Jupiter and were headed home. But the longer they traveled, the less certain they felt about what “home” even meant anymore.
Kaius woke up on the twenty-second day. He blinked, head foggy, eyes dry and then focusing with visible effort. Maya was there when he came to. Rook and Seline drifted in moments later. “Welcome back, Commander,” Rook said, sounding oddly like he used to, deep and sure again. Kaius listened as they explained the successful slingshot, his long unconsciousness, and the strange messages and sightings that had begun to trouble them. He rubbed his face, still moving with care. He opened his mouth to speak and only issued a papery croak. Maya handed him the water bag and he slipped the tube into his mouth, taking small sips for a few moments. Then he spoke again. “My call,” he said finally after clearing his throat. “We keep on pushing forward anyway. But we stay sharp. If something feels off, say so. No assumptions.”
Life aboard Odyssey settled into a new routine with Kaius awake but freed from responsibilities. He observed rather than commanded, watching how the others had adapted in his absence. Maya gave him small tasks in the greenhouse to ease him back into the routine of collective work. It felt strange to her at first, like Kai was a child and she, Maya, the wise grandma. The anomalies continued, and each one chipped away at their confidence. Nothing outside the capsule seemed certain to them, as if their journey was taking them into an unstable world of improvised realities.
With his physical strength regained, and the habit of decision-making partly restored, Kaius began to slot back in. He would drift to the command console during what used to be his shift, offer a random suggestion, nod at their decisions. But his instructions came slower, as if he had to swim up from somewhere deep before he could speak. Sometimes, as he stared at the readouts, his eyes would lose focus, the numbers blurring into something else—Laura’s face, Emma’s drawing, a hospital corridor that smelled of antiseptic and fear. He would shake it off, but others noticed. The first real fracture came during a routine attitude adjustment five days after he woke. Rook was at the controls, Seline feeding him corrections. Kaius floated nearby, watching. The ship gave a small, familiar shudder as the thrusters fired.
“Starboard two degrees,” Seline said.
Rook adjusted smoothly. “Got it.”
But Kaius leaned forward, his hand shooting out toward the override panel. “No—hold that. It’s wrong. The drift is pulling us port. I saw it before. The numbers don’t match what they should.”
Rook froze. “Kai, remember, the numbers don’t always match now. We already ran this sim twice. It’s clean.”
“It’s not.” Something in Kaius’s response unsettled them. His eyes were wide, fixed on something only he could see. “I was there. In the field. The gravity doesn’t let go clean. It leaves hooks. You have to burn harder or it drags you back in.”
Seline glanced at Rook, then back at Kaius. “Commander, the post-slingshot telemetry—”
The menace in Kaius’s silent glare scared both Seline and Rook. His hand closed hard on the console edge. For a moment his knuckles went white. Then, just as quickly, the tension drained from his face. He blinked, looking almost embarrassed. “Sorry. Just… be careful. That’s all.”
“He’s still coming back,” Maya assured quietly as Rook approached her in the galley. She kept stirring her pouch of nutrient paste without looking up. “Give him time. The mind doesn’t reset like a circuit board.” Rook was not convinced. He shook his head and didn’t answer. Maya leaned closer, the intensity of her words surprising even her. “He’s not a liability. He’s fighting something we can’t see. You weren’t conscious in that gravity well the way he was. Whatever pulled him under is still holding part of him. But the rest of him—the part that’s here—is still our commander. He held us together for years. Now we hold him.” Rook’s doubt was written plainly across his face.
Kaius began to unravel in small, jagged pieces. He would wake from what passed for sleep in the observation module and drift through the ship talking to people who weren’t there. Once Maya found him in the greenhouse, talking to the grow trays about “keeping the soil honest.” At a shared meal, he suddenly laughed at something no one had said, then grew deadly serious and started describing memories that he had shared before.
It was painful to witness and impossible to diagnose. Seline and Maya chose not to speak of it, but Rook’s worry grew between them. “He’s slipping,” Rook said to Seline, when Kaius had gone quiet again in the observation module. “What if whatever happened during the slingshot did more damage than we know? What if he becomes a liability?”
The breaking point came during a routine recalibration of the main antenna array, when a new anomaly flared and the stars outside the windows seemed to stutter as if a film had skipped a frame; Kaius, who had been helping with the alignment, suddenly shoved Rook away from the panel and shouted, “Get back! It’s not stars. It’s the hook. The gravity hook. It’s pulling us back. I can feel it—”
Rook staggered but caught himself, and for a brief moment his hand hovered near the emergency restraint on his belt as if preparing to subdue a threat, while he fixed Kaius with a hard stare. “Kai, stand down. That’s an order.” Kaius stared at Rook, no longer recognizing the person in front of him, his breathing shallow and uneven. His attention slipped in and out of the cabin, as though something else had already replaced it. Kai’s shoulders sagged and he pressed both hands hard against his temples, whispering “No…” before the word gave way to Dari, “Nah…,” words that seemed less spoken than uncovered, something younger breaking through as they came out thinner, smaller, and then “Madar…” followed by something fully formed but not meant for them to hear: “Don’t step on that,” he ordered, sharp and instinctive, pointing at nothing. “They’ll see the marks.” Kai’s eyes traced an invisible pattern on the floor. “You have to walk where the stones already are.” Sel had joined Rook, and the two stood an arm’s length away from Kai, watching him carefully, as if ready to catch him.
Kai gave no indication of sensing either of them. His gaze turned inward as fragments surfaced without sequence—Kaius as a child in a sun-bleached courtyard where older boys were playing a game with a worn ball made of wrapped cloth, the kind that never stayed round for long; the moment he stood back, deciding whether to join; you had to learn when it was safe to enter and when it wasn’t, and no one ever explained the difference clearly; the sound of laughter that could turn without warning; the way his name sounded slightly different depending on who called it, and how he learned early not to ask why. “Man tez na-dawidam,” he whispered first, the words slipping out in the old rhythm of his childhood. Then, almost as if translating the thought for himself, his voice changed. “I didn’t run fast enough.” It wasn’t a confession, but an observation. His gaze returned to the cabin, not searching for home exactly, but for the location of his thoughts. “Am I not running fast enough?” he asked, meeting Sel’s puzzled eyes.
“No, Kai,” she assured him. “You’re doing fine. You’re standing in place.” He took her reassurance to heart, looking for the rules to stay consistent long enough to trust them.
“I thought,” he said at last, with the logic of a child trying to make sense of the world, “if you learned the rules nothing would change without warning. I don’t…. I don’t know which home is pulling at me anymore.” Sel stepped forward and put a steady hand on his shoulder, guiding him gently toward the observation module. Rook stayed where he was, breathing hard, jaw tight. For once he had no easy words at hand.
That night—ship time—Maya sat with Kaius for hours. He spoke in fragments, half-dreams spilling out: memories of a mission that hadn’t happened yet, arguments with Houston that sounded like they were from years in the future, a version of the slingshot where they hadn’t escaped at all but had been torn apart and reassembled wrong. Maya didn’t try to correct him. She just listened, her hand on his arm, anchoring him to the present with the simple fact of her presence. “You’re not there anymore,” she told him softly when the words ran out. “You’re here. With us. And we’re not letting go.”
Gradually, the small things changed. Rook stopped hovering near the controls whenever Kaius entered the command module. He started asking for his opinion again—not because he needed the answer, but because he wanted Kaius to know he was still part of the work. Seline began leaving space in her calculations for Kaius to challenge them, even when she already knew the answer. Sometimes he was right. Sometimes he wasn’t. But she stopped measuring his worth by whether he could command.
