The first thing was the sky.
Blue. Impossible, offensive blue — the kind that existed before anything went wrong, the kind that didn't know yet what had happened to the city beneath it. Xavier stared at it for a long moment before he understood that he was looking at it, that his eyes were open, that the heaviness pressing down on every part of him was his own body and not the building anymore.
He was alive.
He catalogued this first, the way he always did. Alive. Eyes functional. Sky above him, which meant he was on a roof, which meant he had made it to the roof, which meant—
The smell hit him like a wall.
It was the smell of what happens when the body stops maintaining itself, and it was everywhere, and it was coming from beneath him, and Xavier turned his head to the right and understood in one look the thing his body had already been telling him since he woke up: he had not landed on the roof.
He had landed on them.
The people who hadn't made it. The ones who had fallen from SKYHAVEN when the gravity gave out and the transports weren't fast enough and the options ran out — they were here, a dozen of them at least, scattered across the rooftop in the postures of sudden stops, and Xavier was in the middle of them, and he had survived because of them, and there was nothing to do with that information except to hold it somewhere very still and very quiet and not examine it yet.
He sat up.
His ribs screamed. One, he thought. Maybe two. He breathed through his nose and let the pain peak and recede and peak again, and when he could think past it he inventoried: left arm, torn along the forearm where something had caught him on the way down, dried now, the fabric of his sleeve stiff with it. Head, a deep throb at the back where he'd taken the worst of the impact. Hands — both of them still wrapped around his blades. He hadn't let go. He wasn't sure when he'd decided not to but here they were, his hands and his blades, the same as they'd always been.
He coughed.
Blood. Not much. He spat it to the side without looking at it and filed it under manageable and deal with it later.
Around him, the rooftop was a still life of the worst kind.
He rolled to his side carefully — every degree of movement a separate negotiation with his ribcage — and got his knees under him, and got upright, and stood on the roof of a building he didn't know in a city that had spent two weeks becoming something it had never intended to be. Below the parapet, Luna City spread out in every direction. The streets were moving. They were always moving now. The walkers drifted in their purposeless patterns, drawn toward sound and light the way water found the lowest point — patient, endless, without the mechanism for stopping.
The rooftop door moved.
Tap.....Tap....
Xavier heard it before he fully turned — the particular wet sound of pressure being applied by hands that no longer calibrated force correctly, the groan of door hardware being worked against by something that did not understand locked, only obstacle.Through the gap where the door frame had warped in the fall, fingers appeared. Grey-pale, insistent, belonging to someone who had died in the stairwell and was now trying to continue up.
"Hhrkkk....hhh.."
More hands behind those. More.
They had heard the impact. They had been hearing it this whole time while he was unconscious.
Xavier exhaled.
He stopped thinking about it — the thing he had learned in the first week of the outbreak, the thing that had taken three days to learn and would take much longer to unlearn when this was over, if this was ever over: *don't hesitate.* Hesitation came from the part of the brain that looked at the walker's hands and remembered what hands were for. That part of the brain would kill you. So he put it in a different room and he closed the door and he moved.
SHLK–!
The first one through the gap he took at the neck — efficient, a single motion, weight transferred to the blade and not his injured side. The second was tangled in the door frame, half through, and he ended it quickly while it was still learning to move in this new context of freedom. The third and fourth came together and he stepped left, used the parapet behind him as a reference point, took them in sequence.
The door stopped moving.
The corridor beyond it went quiet.
Xavier stood in the new silence, breathing carefully, and looked at the blades in his hands, and looked at the rooftop around him, and put all of it in the room he was keeping things in and closed that door too.
He went down.
The building had been residential once. Probably still was, technically — the unit he found on the sixth floor still had photographs on the walls, a half-finished cup of something on the kitchen counter, a child's drawing of a yellow dog taped to the refrigerator with a magnet shaped like a sun. The unit was clear. He checked every room the way he checked every room now, without hope or dread, as pure information gathering. Bedroom: clear. Bathroom: clear. Second bedroom, smaller: clear, a child's bed with a green blanket, the pillow still dented from a head that had been there recently.
He didn't think about the child.
He barricaded the front door with the bookshelf and the kitchen table, wedged a chair under the handle, pushed the couch against the window. Not airtight — nothing was airtight — but enough to buy time. Enough to give him the sound of something trying to get in before it got in.
THUMP—!
Then he sat on the floor of the bathroom and dealt with his arm.
The kit in the kitchen cabinet had been put together by someone who took preparedness seriously — proper bandages, antiseptic, gauze, not just the decorative band-aids that most apartment first aid kits amounted to. Xavier used all of it methodically, cleaned the wound on his forearm until the white gauze came back less red, wrapped it tight, tested the tension. Then he stripped off his shirt and assessed his ribs with his own hands, pressing carefully along the left side until the specific point that turned pain into something specific enough to locate.
One cracked. Maybe two.
He put his shirt back on.
He found food in the cabinets — canned goods, a bag of rice that would be useless without a functioning stove, crackers, a jar of peanut butter that was three-quarters full. He ate crackers and peanut butter standing over the kitchen counter without tasting any of it, because the body needed fuel and this was fuel and that was all it needed to be.
He found new clothes in the bedroom. The resident had been approximately his height. The jacket was thicker than what he'd had, which was a practical improvement. He changed, folded his torn shirt out of old habit, left it on the chair.
Then he sat on the bedroom floor with his back against the bed and his blades across his knees, and he let his brain do the thing it had been waiting to do since he opened his eyes on the rooftop.
SKYHAVEN fell.
The words arranged themselves in the proper sequence. He'd felt it starting. He'd held onto the pillar in the stairwell and he'd held onto the beam and he'd made it to the roof and then his body had made the decision about consciousness without consulting him, and now he was here, in someone else's clothes, in someone else's apartment, and SKYHAVEN was not a city in the sky anymore.
*Where is Nana?*
The question arrived like they always did — quietly, under everything else, the way a compass always found north regardless of what direction you were walking. He went through what he knew: she had been in the officers' quarters when he last had eyes on her. Caleb had been in the city. Caleb would have come back for her — that much was not a question, had never been a question since the moment Xavier had watched the man walk back into an active outbreak zone to find a body that turned out to have a pulse.
*Caleb would have gotten her out.*
He held that. It was a reasonable belief supported by available evidence. He had learned, in the last two weeks, to make decisions on reasonable beliefs and available evidence rather than waiting for certainties that didn't exist anymore.
*She is somewhere. She is with Caleb. She is probably not in Luna City.*
*Probably.*
He breathed through his ribs and listened to the sounds outside. The corridor beyond his barricaded door was quiet. The streets below were not, but the quality of the sound — the direction of it, the way it moved — told him the horde that had come for the rooftop noise was dispersing, drawn away by something else, something further south that had more to offer in terms of stimulus.
Good.
He would sleep.
He would sleep because his body required it and his ribs required stillness and tomorrow was a problem that needed him functional. He would sleep and in the morning he would take inventory of what he had and what the building offered and what the city's geometry looked like from the sixth floor, and he would begin the process of making himself effective in this new landscape.
He looked at the blades across his knees. At his bandaged arm. At the jacket that fit well enough.
*I will find her,* he thought, the same thought he'd had on the rooftop before the dark took him. It had the quality of a fact now, the same quality as one cracked rib, maybe two. Certain enough to operate on.
Outside, something screamed and went quiet. The walkers moved toward it.
Xavier closed his eyes.
Somewhere in the space behind sleep, he let himself think about her laugh one more time — the specific, helpless frequency of it, the way it came out of her like it couldn't help itself, like joy was something that happened to her rather than something she manufactured. The way she'd said *whoosh whoosh* with complete seriousness while describing his blade form. The way she'd eaten from his plate and said *it tastes different from yours* as if that were a perfectly logical explanation.
The way she'd said *when we get to the plaza, I was trying to ask you something.*
"Okay," he'd said.
He still didn't know what the question was.
*I will find out,* he thought.
And then, because the body is practical when the mind gives it permission, Xavier Shen slept.

WHUP—WHUP—WHUP
The helicopter came down out of a sky that didn't know it was supposed to look different yet — still blue, still clean, the same sky that had been above everything for as long as the sky had existed, indifferent to what happened underneath it. It touched down on empty land an hour and forty minutes outside Luna City, and before the rotors had fully stilled Caleb was already out, already moving, already talking into his earpiece with the contained urgency that his team had learned to recognize as serious in a way that panic never quite achieved.
"Perimeter first. Medical tent second. Fire — controlled, low, not visible from the road. Water inventory. Who's injured, who's mobile, who needs immediate attention."
The land was flat, scrubby, the kind of terrain that wasn't good enough for anything and had therefore been left alone. Good cover in the tree line to the north. A natural depression to the east that would channel wind and offer shelter. He'd chosen the landing site from the air in forty seconds and didn't second-guess it now.
His team moved.
They had learned, in two weeks, that Caleb Xia gave an order once.
Nana stayed close.
She hadn't let go of his sleeve since they'd disembarked — one hand gripped in the fabric of his uniform, the other on the hilt of her sword, and she was scanning the treeline with wide eyes that hadn't fully decided whether to be afraid or angry yet. He knew that look. He'd watched that look evolve since she was eight years old and the world had offered her something she didn't have language for yet.
"He's not here," she said.
Not a question. A statement of a fact she was still deciding whether to accept.
Caleb closed his eyes for exactly one second.
He was very good at this — at the specific discipline of not examining certain thoughts in the middle of doing necessary things. He had gotten better at it over the last two weeks. He had a great deal of practice with it over the last twenty years. The chest pocket of his uniform held three objects: a star necklace, a butterfly phone case, his father's gun. None of those things required examination right now. None of the feelings behind them did either.
He opened his eyes.
"He's not here yet," he said.
Nana looked up at him.
Her face did something complicated. He watched it happen — the fear cycling through and coming out the other side as something quieter, something that was not hope exactly but was the architecture that hope was built on. She trusted him. She had always trusted him, since she was five years old and learning that trust could be a thing you extended outward without losing it.
It was the thing that made him most proud of her. It was also the thing that was hardest to hold right now, with the weight of what he'd seen on the way out.
"How do you know?" she asked.
"He's S-Class," Caleb said. "Best record in the division. I read his file."
"You read his file?"
"Three times."
She stared at him. Something flickered in her expression — not quite a smile, but its first cousin. "Gege."
"He's resourceful," Caleb continued, as if she hadn't said anything. "He's practical. He knows how to operate alone in hostile terrain — his solo record is longer than most hunter teams' combined. If anyone survives in that city until we can get back in, it's him."
He said it evenly. He said it because it was true and because it was what she needed and because the distance between *saying something because it is true* and *saying something because it is needed* was something he had stopped examining a long time ago.
Nana held his sleeve a little tighter.
Then: "Okay," she said.
The same way she'd said okay in chapter fifteen, in the apartment, not hope but the structure that held you while you waited for hope to catch up. He recognized it. He had always recognized the specific language of her.
"Okay," he agreed. "Come on. I need your eyes on the eastern treeline while I get the medical station set up."
She straightened. The hand on the sword shifted into a grip that meant business.
"What am I looking for?"
"Anything that moves wrong."
"Got it."
She moved to his left. Three steps ahead of him, already scanning, already useful. He watched the back of her head — the red hair, the starfish clip sitting slightly off-center the way it always was, the way he'd never once told her because she never seemed to notice and he liked the small imperfection of it — and then he looked at the treeline and got to work.
They set up camp in forty minutes.
Emergency tents in a cluster tight enough for body heat, far enough apart for multiple escape routes. A fire that burned low and produced minimal smoke, positioned in the depression where it would be least visible from the road. Water rationed and logged, the count precise, Caleb keeping the numbers in the same part of his mind where he kept all the numbers. Medical tent at the northern end, staffed by the two people in the group who had medical training, and Nana who had a level of fearless practical competence with bandaging that Caleb suspected came from years of minor hunting injuries she had cheerfully not mentioned to him.
She moved through the medical tent efficiently, handing supplies, talking to the people who were badly enough scared that they needed someone to talk to them. He watched her from the entrance when he could spare the attention — the way she crouched to be at eye level with a child who wouldn't let go of a stuffed frog, the way she said something quiet that made the child's grip loosen slightly. The way she looked up between each person and scanned the camp with eyes that were doing two jobs simultaneously.
She was looking for silver hair.
He knew. He always knew what she was looking for, in the same way he always knew when she was about to tip over from tired into exhausted, or when she was holding something in instead of saying it, or when she'd eaten and when she hadn't. Twenty years of paying attention accumulated into a kind of fluency.
He pressed his hand to his chest pocket.
He went back to work.
Night came in stages, the way it always did here — the light changing first, then the temperature, then the quality of the silence shifting from daytime silence to the particular nighttime quiet that made the sounds within it more present. The camp settled into a watchful version of rest. His team cycled through perimeter shifts. The civilians slept with the heavy blunt sleep of people who had spent everything they had and needed their bodies to reset.
Nana sat at the edge of the camp, her back to a tree, the pink bunny in her lap and her sword unsheathed beside her. She had her knees drawn up and her chin resting on them and she was looking at a point in the middle distance that was not the treeline and not the fire and not any of the people around her.
Caleb brought her a ration pack and a blanket and sat down beside her without asking.
She took both without looking at him.
For a while they just sat.
"Do you think he's cold?" she asked eventually.
He knew who 'he' was.
"He'd find shelter," Caleb said. "First thing. Defensible position, supplies, then treat injuries."
"He has injuries?"
"Anyone who was in SKYHAVEN when it fell has injuries."
She went quiet. Her fingers found the bunny's yellow ribbon and turned it slowly.
"He had his blades," she said. Not a question. A piece of comfort she was building, piece by piece, from available materials. "He always has his blades."
"He had his blades," Caleb confirmed.
"And he knows how to— he's good at surviving. He was a solo operator for years. He knows how to—" She stopped. Swallowed. "He knows how to be alone."
Caleb looked at the fire. At the low clean flame of it, burning exactly as hot as it needed to and no hotter.
"He does," he said.
She leaned her head against his shoulder, the way she'd been doing since she was small enough that he had to lean considerably further down to make it possible. Now she barely had to reach.
"We're going to go back for him," she said.
"Yes."
"When the route is clear enough—"
"Yes."
"You're not just saying that."
"Nana." He said her name the same way he always said it — with the specific weight of twenty years of meaning it. "When have I told you something I didn't mean?"
She thought about it. Genuinely thought about it, because she was honest even when honesty was inconvenient.
"Never," she said.
"Then."
She exhaled. Long, slow, the kind of breath that carries something with it when it leaves.
"Okay," she said. The third time today she'd said it, each one slightly different in weight. This one was the heaviest and the most certain.
She kept her head on his shoulder.
He didn't move.
Above them, the sky that had been blue was now fully dark, scattered with stars that had been there long before Luna City and would be there long after, indifferent and permanent and beautiful in the way that things are beautiful when they don't know they are.
He pressed his hand once to his chest pocket.
He looked at the fire.
He did not examine any of the things that lived in the room he kept them in. He simply sat beside her, in the cold, at the edge of the camp, and was present in the way he knew how to be present: completely, quietly, without requiring anything in return.
Far away, through the dark and the distance and the city that moved between them—
Xavier lay on a stranger's bedroom floor, his blades across his knees, his ribs negotiating with every breath, the sounds of the corridor cycling through the stages of night outside his barricade.
He was not asleep yet.
He was looking at the ceiling — water-stained, ordinary, the ceiling of someone's ordinary life — and he was thinking about the question she'd said she wanted to ask him.
"When we get to the plaza. When this is over."
He thought about her face when she'd said it. The specific quality of her voice. The way she'd looked at him like she was deciding whether the timing was right and had decided it wasn't, not quite, not yet.
*I know what the question is,And I know what my answer is*
Outside, the walkers moved through the corridor and moved on. The city made its nighttime sounds. Something fell somewhere distant, the structural settling of SKYHAVEN finding its final shape in the streets below.
Xavier closed his eyes.
Stay alive, he thought, in the direction of wherever she was. Not a prayer — he wasn't built for prayer. A statement. An instruction. A fact he was making true through the force of intending it.
"Stay alive. I'm coming."
He breathed through his ribs.
He slept.
