The grocery store still had music playing.
That was the detail that broke something in Kai. Not the empty streets, not the cars abandoned mid-turn with their doors hanging open like the drivers had simply evaporated, not even the dark windows of a thousand apartments stacked above them like dead eyes. He'd handled all of that with the particular focused calm of a man doing long division in his head to avoid thinking about what the numbers meant.
But the music.
Soft. Tinny. Coming from somewhere in the back of the store through a speaker system still running on backup power — an old song, something with piano, the kind of song that existed specifically for the background of ordinary afternoons. It was still doing its job. Playing for a store full of nothing, in a city full of nothing, completely unaware that its entire audience had somewhere stopped existing.
Kai stood in the doorway and listened to it for three seconds.
Then he walked inside and started checking the shelves, because the alternative was standing in a doorway listening to dead air pretend to be alive, and he'd decided somewhere on the landing ramp that there was a version of today where he got through it without falling apart, and he was going to find that version if it killed him.
Arin moved through the aisles slowly.
This was his method — had always been his method, in training and in mission and in the eleven months of close quarters that had given his crew an intimate understanding of how he functioned under pressure. He went slow when others went fast. Not hesitation. Inventory. His eyes moved across surfaces with the systematic patience of someone who had learned, early, that the thing you missed was always the thing that mattered.
Canned goods. Most still present, dusty, undisturbed. Perishable section — dark, the refrigeration dead, but no smell of rot. He paused at that. Opened a case. The produce inside was dried and shriveled but not decayed in the way it should have been after however long this had been going on.
"Lira," he said quietly.
She was two aisles over. He heard her footsteps stop. "Yeah."
"What's your read on timeline? Based on the state of things."
A pause. Lira Chen had a medical background — not a doctor, but the kind of field medic who paid attention to the right details. "At least a year. Maybe more."
"The produce in this case says less."
Her footsteps moved toward him. She appeared around the end of the aisle, flashlight sweeping, and came to look at what he was looking at. She was quiet for a moment. "That's not right."
"No."
"Decomposition should be much further along."
"Yes."
She looked at him. He looked at the dried vegetables. Neither of them said the next part, which was: something preserved them. Because saying it meant asking what, and asking what meant acknowledging that the category of possible answers included things they weren't ready to name yet.
"Keep moving," Arin said.
Professor Ren found the handprint.
He didn't announce it immediately. Arin was watching him — had been watching him since the wall outside, since the turned screen on the shuttle, since the six hours of silence from Mission Control that Ren had apparently known about before any of them — and he saw the moment Ren's light found the shelf near the back. Saw the older man go very still.
Saw him look at it for a full four seconds before he said: "Someone's been here. Recently."
Lira crossed to him. Kai emerged from somewhere in the back, scanner still running, its soft beeping the only constant sound beneath the piano music.
The handprint was on the side of a shelf at roughly chest height. Dark reddish-brown. Dried but not long dried — a week, maybe less, if Arin's estimate was right, and in this city his estimates were already proving unreliable.
"Survivor," Kai said, and the word came out with something almost like hope in it.
"Possibly," Ren said.
Just that. Possibly. With a careful flatness that made Arin look at him directly for the first time since the store.
"What else would it be?" Kai asked.
Ren didn't answer. He moved his light slowly along the shelf, following a trail of partial prints that led toward the back room. His expression was the practiced neutrality of a man who had decided what he was going to say and what he wasn't, and had made that decision before this conversation started.
Arin filed it. He was running a significant file on Ren today. It was getting heavy.
"Movement," Lira said quietly.
Everyone stopped.
From behind the back room door — a sound. Soft. Weight shifting on a hard floor.
Arin moved to the door first, the way he always moved first, the way that was reflex by now and not heroism. He pressed his back to the wall beside the frame. Looked at Kai, who raised his scanner and angled it toward the door and checked the reading and went very still.
"Life sign," Kai said, almost whispering. "Human. Weak."
Arin opened the door.
She came out fast and wrong — stumbling into the light with her hands up in a gesture that might have been surrender or might have been trying to catch herself from falling, it was impossible to tell. Her eyes found them and went enormous, and for one second Arin saw something purely human in her face: shock, relief, fear, all of it arriving simultaneously.
Then the flashlights found her skin.
The veins beneath were dark. Not bruised-dark — dark dark, the color of something that had stopped being blood. They traced her neck, her jaw, the backs of her hands, and they moved. Not quickly. But they moved, the way a river moves — with the slow, indifferent patience of something that has its own direction and no particular interest in yours.
"Help," she said. The word came out careful, deliberate, like she was reading it off something. "Run. They're—"
She stopped.
Her head dropped forward. She caught herself on the doorframe, one hand gripping the metal, and Arin watched her knuckles whiten and then watched the dark veins beneath them pulse once, twice — and then she raised her head and looked directly at him.
Not at the group. At him.
Her eyes were wrong. Not fully — not the total blankness he'd see later, the white-eyed absence of whatever had once lived behind someone's face. There was still something there, something trying to surface, like a voice calling from the bottom of a well.
She said something. It was very quiet, and the piano music chose that moment to swell from the back of the store, and Arin only caught the shape of one word on her lips.
Careful.
Then she convulsed, slid down the doorframe, and stopped moving.
Lira was beside her before anyone spoke. Medical reflex — fingers at the throat, reading pulse, the automatic competence of someone who dealt with worst cases by dealing with them.
"Pulse stopped," she said. "She's gone."
Kai had taken two steps back. He was looking at the dark veins on the woman's skin and holding his scanner in front of him with both hands like it was something solid to hold onto. "What was that in her veins?"
"Don't touch her," Ren said immediately.
Everyone looked at him.
He was standing further back than the rest of them. He'd been standing further back the whole time, Arin realized — since they entered the store, since the handprint, since the back room. Always slightly outside the circle. Always with a clear path to the door.
"Ren," Arin said.
"It's an infection vector. We don't know the transmission method. Don't touch her, don't touch anything she touched, and we need to leave this location." He was already moving toward the front of the store. "Now. Before—"
The sound came from outside.
Low. Wet. The particular register of something large moving through narrow space with no concern for the space it was moving through. Then more of the same sound, from a different direction. Then a third, and the piano music finally, mercifully, stopped — as if even it understood that this was the wrong moment for an ordinary afternoon.
Lira killed her flashlight. Kai killed his. Arin stepped to the store window and looked out through the dust-filmed glass into the grey morning street.
They were coming from the far end of the block. A dozen of them. Maybe more — it was hard to count because they moved with a strange coordination, not the lurching stumble of the woman inside but something more deliberate, a pace that was almost comfortable. Their eyes caught no light. Their veins, even from here, were visible.
"Back exit," Arin said. Not loud. Not quiet. The register of a man who has decided.
"Agreed," said Lira.
Kai was already moving. Ren was already gone.
They came out into an alley that smelled of old rain and mineral air and ran parallel to the main street. Arin took the rear, the way he always took the rear, watching the corner they'd turned as they moved. Nothing followed. The figures outside had not reacted to the store door opening, had not changed direction, had continued their slow and deliberate progress down the far end of the block.
Which was almost worse.
Because it meant they hadn't been running from them. They'd been moving toward something. Something further up the street, past the store, past the alley. Something that held more interest for them than four people emerging from a building.
Arin kept that observation to himself. His file on today was very full.
They found a defensible position four blocks south — a parking structure, third level, concrete walls and two entry points they could monitor. The kind of space that had nothing a person would want and therefore nothing the figures outside seemed interested in.
Kai set up his scanner at the entry ramp. Lira inventoried the supplies they'd pulled from the store — four cans, two liter bottles of sealed water, a flashlight with working batteries that wasn't theirs. Someone else had been here too, recently. The light was still warm to the touch.
Arin sat with his back against a concrete pillar and looked at the city through the structure's open side.
The wrong-blue sky was brightening slightly. Not dawn — the sun was already up, somewhere behind the ash and cloud — but a grudging increase in grey that passed for day in this city now. Below, the street was empty again. Whatever the figures had been moving toward, they'd reached it or moved past it. The silence had come back, complete and mineral and patient.
He looked at his watch. 7:42 AM. The second hand frozen. 3:14.
He wound it.
Something was wrong with his hands.
He noticed it the way you notice something at the edge of your vision — not the thing itself but the shadow of it, the shape of an absence. He looked at his palms. Nothing there. He turned them over. Nothing. He pressed his fingers together and felt the familiar geography of eleven months of manual work, the calluses and small scars of a working astronaut's hands.
Everything normal.
But when the woman had convulsed and slid to the floor and Lira had pronounced her dead — Arin had felt nothing.
Not the shock of watching someone die. Not the sick lurch that he knew from experience, from the two crew losses in his second mission, from the training accident he'd witnessed at twenty-six that still visited him occasionally in dreams. He knew what it felt like when a person stopped being a person in front of him. He knew the specific weight of that knowledge in his chest.
He had felt none of it.
He had looked at her and run a threat assessment and moved his team to the exit.
It was the right call. It was absolutely the right call. You did not stop to grieve in an active threat environment, that was not protocol, that was not leadership.
But he had not felt it. Not even beneath the assessment. Not even in the part of him that usually ran underneath everything else, the part that kept the score of what this cost.
It was as if that part of him was simply quiet.
He told himself he was in shock. That the numbness would arrive properly later, in waves, the way it always did when the crisis gave you enough space to feel it.
He told himself he believed that.
He wound the watch again. It didn't need it. He'd wound it thirty seconds ago.
Lira appeared beside him and sat down without speaking. She had a habit of doing this — arriving in proximity and waiting, not filling the space, just making herself available. He'd always found it one of her better qualities.
"She said something," Lira said after a while. "Before she fell. What was it?"
Arin looked at the city. "I didn't catch it."
This was the first lie he told anyone since they landed.
It would not be the last.
Kai's scanner beeped once — a sound it made for routine readings, not for alerts. He checked it. Frowned.
"Arin."
"Yeah."
"You're running warm."
Arin looked over. Kai had turned the scanner toward him, the readout showing biometric data — the kind of ambient scan the device ran constantly, cataloguing the crew. Standard equipment. They'd all been scanned ten thousand times.
"How warm?" Lira asked.
"Point eight above baseline." Kai looked at the device, then at Arin. "It's not a fever. The distribution's wrong for a fever. It's like your peripheral temperature dropped to compensate your core going up."
"That sounds concerning," Arin said.
"Yeah."
"Or it's re-entry stress on the body."
"Yeah," Kai said again. Differently.
He put the scanner back in his kit. He didn't turn it off.
Arin looked out at the city and thought about a woman's lips moving around a word she shouldn't have known to say to him. He thought about a frequency that had nothing on it producing a voice. He thought about the produce in the case, preserved past its time, dried but not decayed.
He thought about how calm he was.
He wound the watch a third time.
It doesn't run, you know, his mother had said once, watching him with the careful amusement she reserved for his more stubborn habits. Winding it doesn't do anything.
I know, he'd told her.
Then why?
He hadn't had an answer then. He didn't have one now.
He sat with his back against the pillar and watched the wrong-colored day grow slightly brighter over a city full of figures that moved like they knew exactly where they were going, and he felt — not fear, not grief, not the appropriate weight of what he was seeing.
He felt patient.
That was the first wrong thing.
