Breakfast on day five was rice and tinned fish and the specific silence of people who had stopped pretending everything was fine.
Not loud silence. Not angry.
Just — the silence of a room where the math had become visible.
Ren counted the bowls while he was helping Hiro set up.
Seventy-four people. Seventy-four bowls.
He counted them twice.
Seventy-five.
He stood there for a moment. Looking at the extra bowl. Plain ceramic. Chipped on the rim. Sitting at the end of the row like it belonged there.
He looked around the room.
Seventy-four people. He counted them too.
He picked up the extra bowl and put it back in the cabinet and didn't say anything about it.
He almost convinced himself he'd miscounted.
Almost.

The fog protocol argument started at noon.
Not dramatically. Not with raised voices. The way real arguments started — quietly, in a corner, between two people who had been carrying something for too long and ran out of room to carry it at the same time.
The man's name was Daisuke.
Thirty-something. Former office worker from the upper district. He'd come over the bridge with the first group on the morning of the collapse — one of the original seventeen Arcaders. He'd been quiet through all of it. Competent. Reliable. The kind of person you stopped noticing because they never caused problems.
He was causing one now.
Ren heard it from across the community centre. Not the words at first. Just the tone. The specific register of someone who had decided something and was no longer interested in being talked out of it.
He moved closer.
---
Daisuke was talking to Nadia.
Or not talking. Standing. His arms at his sides. His voice flat in a way that wasn't calm — the flatness of something that had been pressed down too many times and had stopped springing back.
"I'm not staying inside," he said.
"Daisuke—"
"I've been inside for five days. I was inside for four days before that in the arcade. I need to—" He stopped. Started again. "I need to go outside."
"The fog hour starts in three hours," Nadia said. Her voice careful. The voice she used when she was managing something that could go either way. "After. You can go outside after."
"I don't want to go outside after. I want to go outside now. I want to walk to the harbor and I want to stand there for twenty minutes and then I want to come back."
"The Changed have been at the northern edge every fog hour for a week. If you're outside when the fog—"
"I know the protocol." His voice went flatter. "I helped write the protocol. I know what happens if you're outside during fog hour."
"Then—"
"I don't care," he said.
Not angry. Not irrational.
Just done.
Nadia looked at him. The practiced efficiency of someone calculating how hard to push and whether it would help.
"One hour," she said. "Harbor and back. Before the fog."
"Thank you," he said.
He left.
Nadia watched him go.
Then she looked at Ren.
"Third one this week," she said quietly.
"Who else?"
"Kenji. Two days ago. And the woman from the harbor ward — Sato — she went outside during the last fog hour."
Ren looked at the door Daisuke had walked through. "She came back."
"Yes." Nadia picked up her clipboard. "She couldn't explain why she'd gone out. She said she didn't remember deciding to."

He found Lena in Haru's room.
Not the kitchen table this time. Haru's actual room — small, at the back of the community centre, the window facing east toward the low hill. Two chairs. A desk with more papers than the clipboard had suggested.
Haru was at the desk. Lena was in the other chair. Both of them looking at something spread across the surface.
He knocked on the open door.
Lena looked up. Read his face.
"Come in," she said.
He sat on the floor. Told them both. Daisuke. The harbor. Kenji and Sato. Sato not remembering deciding to go outside.
When he finished Haru was quiet for a moment.
Then she said: "The forgetting."
"What?"
"That's what my mother called it." She folded her hands on the desk. "When the fog is frequent enough, long enough — people start forgetting small things. Recent decisions. Where they put something. Whether they'd already eaten." She paused. "She said it was the water. The pulse. Getting into the spaces between thoughts."
Ren thought about the seventy-five bowls.
He almost said it.
Didn't.
"How bad does it get," Lena said.
"She didn't say." Haru looked at her hands. "She said the ones who went into the water had been forgetting for weeks first." She paused. "She said they always looked calm. Walking to the harbor. Getting in. Like they were going somewhere familiar."
Silence.
Outside the east-facing window, the low hill was visible. The scrub vegetation. The sky above it going the particular grey of late afternoon.
Three hours until fog.
Maybe less.
"Daisuke," Ren said.
"He's been checking the harbor window every morning," Lena said. "For three days." She said it the way she said things she'd already processed. Filed but not yet shared. "I noticed. I thought it was grief. He had family in the upper district."
"He might still," Ren said.
"He might." She looked at the papers on Haru's desk. "Or it might be something else."
He looked at her.
The thing the diagnostic had named.
*Make Lena wrong.*
She'd filed it as grief.
She might have filed it wrong.
He didn't say that. Not yet. She was already recalculating — he could see it in the quality of her stillness. The specific kind that meant she was revising an assumption she hadn't known she was making.
"I should have—" she started.
"You had eight days of food and accelerating fog and twelve pages of clipboard," he said. "You can't watch everyone."
She looked at him.
Not the recalibration look. Something quieter.
"I should have watched him," she said.
He didn't argue.
She was right.
She was also human.
He didn't say either of those things.

Daisuke came back from the harbor forty minutes later.
He came in through the community centre's main door, took off his shoes, put them neatly against the wall, and sat down at one of the tables.
He looked better.
That was the thing. He looked genuinely better — some of the flatness gone from his face, a quality of having exhaled something he'd been holding.
Ren watched him from across the room.
Better was good.
Better was also what Sato had looked like when she came back from outside during fog hour.
He filed that.
---
The fog arrived at 6:39pm.
Eight minutes earlier than yesterday.
The community centre went through its ritual. The dimming. The quieting. The movement toward interiors.
But something was different tonight.
Ren felt it before he could name it.
A quality to the silence that was — off. Not the disciplined quiet of people following protocol. Something underneath it. The silence of a room full of people who were all thinking about the same thing and not saying it.
He looked around.
Daisuke at his table. Looking at his hands.
The woman from the harbor ward — Sato — near the window. Her back to the room. Her face toward the glass.
Two of Haru's original eleven sitting together, not speaking, their postures subtly oriented toward the north wall. Toward the harbor.
A boy — one of the three children, maybe ten — standing near the community centre's side door. Just standing. Not playing. Not talking to anyone.
Just standing.
Looking at the door handle.
Ren stood up.
Crossed the room. Sat beside the boy. Didn't touch him. Just sat close enough to be a presence.
"Hey," he said.
The boy looked at him.
His eyes were normal. Focused. Present.
"I was going to get some water," the boy said.
"Kitchen's over there," Ren said. "I'll come with you."
They went to the kitchen.
The boy got his water.
By the time they came back the side door moment was over — whatever it had been.
Ren sat with him until he went back to the adult he'd been assigned to.
Then he looked across the room at Lena.
She'd been watching.
She'd seen the boy at the door.
Her expression — not the recalibration look. Not the calculation look.
Something he didn't have a name for yet.
Something that looked like the moment before afraid.
---
The fog hour ended at 8:51pm.
Seventy-two minutes.
He wrote it down on the back of his hand. Didn't have Petra's notebook. Didn't have Lena's clipboard.
Just his hand.
*Day 5. 72 min.*
He was still looking at it when Axel appeared beside him.
Sat down without being asked.
Didn't say anything for a while.
Then: "Daisuke."
"Yeah," Ren said.
"I've been watching him since day two." Axel's voice was quieter than usual. The forward momentum sitting still. "He stands at the harbor window every morning for exactly the same amount of time. Seven minutes. I counted."
Ren looked at him.
"Every morning?"
"Every morning." He looked at his hands. "I didn't say anything because I thought—" He stopped. "I don't know what I thought."
"You thought it was grief."
Axel was quiet.
"Yeah," he said.
Ren looked across the room. At Daisuke, still at his table. At Sato, still near the window. At the side door where the boy had stood.
"How many," he said.
Axel understood the question.
"Six," he said. "That I've noticed. Probably more I haven't."
Six people.
Out of seventy-four.
Ren thought about the seventy-five bowls.
He thought about telling Lena.
He thought about her expression when she'd watched the boy at the door. The moment before afraid.
She already knew something was wrong.
She'd filed Daisuke as grief and she'd been wrong and she already knew that.
Tomorrow, he thought.
Tell her tomorrow.
Tonight she needed to sleep.
He looked at his hand.
*Day 5. 72 min.*
Then he looked at the cabinet where he'd put the extra bowl.
He thought about going to check if it was still there.
He didn't.
Some things you didn't check.
Because if the answer was wrong you couldn't unlearn it.
And he needed one more night of not knowing.
