Nothing Happened

The log said nothing happened. Nakagawa read it every evening and it said so every evening, in Aravena's voice, at the end of the shift's entry, exactly as ordered: Nothing happened. And under it, in the file where only the survey lead wrote, Nakagawa kept the count of how many times that had been true.

It was a plain number and it went up by one a shift. Egede thought it was a joke that had gone on too long. It was not a joke. A survey that has been shown a thing it does not understand has two choices, and one of them is to do something about it, and the other is to write down, carefully, for as long as it takes, that it has not. Nakagawa had chosen the second, and the count was the second, made visible.

But a log that says nothing happened is not the same as a log with nothing in it. Nakagawa read the unit's channels every evening beside the count, and the channels were full.

The boulders, first. The survey had logged them since the first month: a shift of rock somewhere below the margin, felt more than heard, and then, after an interval the party had long since learned to measure, the thermal profiles at the margin gone. The adults withdrawing. The party had logged it so many times that nobody saw it any more, the way you stop seeing a door you go through every day.

Nakagawa laid the shifts out in a row and looked at them for a while.

One on every arrival. Not some. Every arrival of the party in the upper levels had a boulder shift before it, below the margin, before the party was anywhere in sight of the margin — before, Nakagawa checked, the party's light could have been seen from it. And then the withdrawal, by the interval. Two years of it. They announced themselves every single time, and then they left the place to the party, every single time.

And the party had walked in, every single time, without a sound that meant anything, and never once done the same.

Nakagawa did not file that as a finding. Nakagawa filed it as an observation, in the plainest words there were: the party has never announced itself. Then sat with it.

Then the sound channel, which Nakagawa had been reading for some shifts now and had told nobody about. At the end of every shift, after the others' voices had gone up the passage and faded, there was one voice left at the bottom, low, and it said a short thing that went up at the end, and then there was a long quiet, longer than anybody waits for anything, and then footsteps going up.

Was that all right?

Nakagawa knew whose voice it was. Nakagawa had said nothing to Aravena, and was not going to, yet, because a thing said to the dark is not a thing said to the survey lead, and a survey lead who cannot tell the difference has stopped being one.

Egede had noticed. Egede noticed most things eventually.

"You talk to the dark," Egede said, at the junction, not unkindly, while Aravena was kneeling to the unit.

"You talk to the imager."

"The imager doesn't answer."

"Neither does the dark," said Aravena. "Log. Shift fifty-eight. Upper junction. Party of three. Nothing so far." The unit hummed, once, low. "The unit answers."

"The unit's built to."

"So might they be," said Aravena, and did not know why they had said it, and went red, and Egede let it go, which was a kindness, and went back to the far wall.

Later in the shift Egede called them both over to the imager, because there was a thing on the playback worth seeing, and there was.

It was the margin, from the top of the shelving, the way the imager saw it when the party's light was swung that way: broken ground going down into dark, and, at the bottom of what the light could reach, two warm shapes, large, still. Adults. The party had seen the shapes a hundred times and never nearer. On the playback the light swung, and as it swung the rocks on the shelving threw their shadows out across the ground below, long and moving, the way shadows move when a light does. The two shapes did not move when the light's edge reached them. They moved when the shadow reached them. A rock's shadow swung across the ground toward them and they were gone, both, back into the dark, by the time it got there.

Egede ran it again. Same thing. Egede ran the one from the shift before. Same thing: the light could touch them and they held; the moving shadow could not.

"They don't like the shadows," said Aravena.

"Nobody likes shadows."

"They live in a place with none," said Nakagawa.

Egede and Aravena looked at the survey lead.

"None that move," Nakagawa said. "Think about it. The light down there is the fungus, and the fungus has no cycle and does not go anywhere. Nothing below the roof has ever moved a shadow. A shadow, to them, is a thing that stays where it is. Then we come down the passage swinging a light, and every rock we pass throws a shape across the floor that gets up and walks. We are the first thing on this world that has ever done that." A pause. "I would be wary of it too."

Aravena thought of the light held low, at the bottom of the passage, every shift, facing the dark. Held low so it did not throw anything. Aravena had done that without thinking why. It had seemed like the polite way to hold it.

That evening Egede made the argument properly, at the station, with the wind going.

"He brought our unit back and stood it on its feet at the exact place we stopped. That is a courtesy. You don't file a courtesy under nothing happened for sixty shifts and call it caution. You answer it. We take something down to the line and leave it. Something small. Something that says we saw."

"And leave it," said Nakagawa.

"Yes."

"Say the rest of the rule."

Egede said it, because Egede knew it as well as anyone. Nothing stays on this world that the planet would keep if the station were abandoned.

"A thing left at the line," said Nakagawa, "is a thing left. Whatever it says. If we cannot take it back at will, it is not a message, it is the first piece of us this planet keeps, and we agreed there would not be one."

"Then what do we do?"

"I don't know yet. That is what the count is for."

Egede did not like it, and said so, and it went in the file too, because a refusal kept without the thing it refused teaches nobody anything.

Then Nakagawa did the thing that had been waiting some shifts to be done, and turned to the third of the party, who had said nothing all evening, and who had knelt to the unit on the line and filed no reading.

"You were the one who read its log. What did you think it was?"

Aravena took a while. Nakagawa let the while be as long as it liked.

"It wasn't dropped and brought back," Aravena said. "And it wasn't a line. It was put where we would find it. Facing us. On the exact place where we stopped." A breath. "Like a thing at a door."

"And what does one do at a door."

"You knock," said Aravena, and then stopped, and Nakagawa watched the rest of it arrive, the way you can watch a thing arrive in a face. "They knock. Every time. That's what the boulders are. Before we've even seen the margin, every time — they've knocked, and then they've stood back. And we've never — we walk straight in. Two years. We've never once —"

"No," said Nakagawa. "We have not."

The wind went. Egede, for once, said nothing at all.

"So we knock," said Aravena.

"Not today," said Nakagawa, and meant it exactly, and no more than that. "Write it down. The log says nothing happened, because nothing has. And under it, in my hand, that the party has never announced itself. Noted. And then we sleep on it, all three of us, and I mean sleep, and we see what it looks like in the morning, which is the only test this survey has ever trusted."

Aravena wrote it down. Nakagawa wrote the other line, and the count went up by one, and for the first time since the unit was lifted the count had something written under it.

Last up the passage, the next shift, the way it always was now. The light held low.

Aravena turned round at the bottom, where the third passage came in, and faced the dark, and asked it, the way Aravena had asked it every shift since the unit was lifted, whether that was all right. It went up at the end. Aravena waited, for as long as it is polite to and then a little longer, and nothing answered, and the unit on Aravena's back hummed once, the way it did, and stopped.

And Aravena stood there one moment more than usual, because a thing had arrived the evening before and had not finished arriving.

It was this. Aravena had been asking, every shift, whether it was all right — afterwards. After the party had come down the passage swinging its light and walked to the junction and worked and gone. Asking afterwards. Asking from behind their backs, in the dark, when the working was done and there was nobody there to ask. And the ones who lived here did not do that. They knocked before. They shifted a stone before they were anywhere near, so that whoever was in the place knew that someone was at the edge of it, and then they stood back, and left it. And you cannot ask somebody whether it is all right for you to be in their place when you have never once let them know you were coming.

Nobody answers a question you ask from behind their back. Aravena had been asking it for sixty shifts and had never once thought that the dark's silence might be manners.

Aravena went up.

The log that shift said that nothing happened. That was still true. But the party knew a thing it had not known, which is a different kind of nothing, and Nakagawa's line was still there under the count in the survey lead's own hand, and nobody had struck it out.
