下山经过面包店时，Clay 让其他人先等，自己进去了一趟。
Passing the bakery on their way downhill, Clay asked the others to wait and went inside.
诺拉正在称明早要用的面粉。秤盘往下一沉，她用勺子舀出一点，抬头看他。
Nora was weighing flour for the next morning. The pan sank; she scooped a little out and looked up.
“又要晚？”
“Late again?”
“今晚在主塔吃。可能还要看档案。你别等我。”
“Supper at the main tower tonight. Then perhaps the records. Don’t wait for me.”
他说完，拿走柜台上那张写着傍晚回来的纸，在背面补了新的安排。诺拉没有追问，只把 Miso 的水碗推给他看。狗喝了不少水，正在炉边睡觉，前爪搭着那双大鞋。
He took the note promising to return by evening from the counter and wrote the new arrangement on its back. Nora asked no further questions. She merely pushed Miso’s water bowl toward him. The dog had drunk plenty and was sleeping beside the oven, his forepaws resting on the large shoes.
“它下午出去过。”她说。
“He went out this afternoon,” she said.
“谢谢。”
“Thank you.”
Clay 弯腰摸了摸狗的头。Miso 睁开眼，看清是他，舔了下鼻子，没有起来。他忽然觉得这样很好。狗不必每一次都跟他走。
Clay bent to stroke the dog’s head. Miso opened his eyes, saw who it was, licked his nose, and stayed down. Suddenly Clay thought that was good. The dog did not have to follow him every time.
Dr. T 站在门外，手里拎着空篮子。诺拉看到他，称面粉的动作停了一下。
Dr. T stood outside holding the empty basket. Nora paused in her weighing when she saw him.
“东岸的新报告呢？”她问。
“Any new report from the east shore?” she asked.
“还没有能确认的变化。”
“No confirmed change yet.”
“上回你也是这么说。”
“That’s what you said last time.”
Dr. T 没有躲开她的目光。
Dr. T met her gaze.
“如果说有希望能回来，我就需要拿出依据。今天还没有。”
“If I say there’s hope of a return, I need evidence. I don’t have any today.”
诺拉的嘴唇抿紧，低头把多出来的面粉倒回袋里。
Nora pressed her lips together and tipped the excess flour back into the sack.
Clay 站在两人之间，没替任何一方接话。出门时，他听见秤砣在柜台上重重磕了一声。
Standing between them, Clay did not speak for either side. As he left, he heard a scale weight strike the counter hard.
主塔门前的台阶修过。旧石头保留下来，中间磨平的地方嵌进新的粗面砖。Clay 走到第三阶时，脚自然避开以前那处松石，低头才发现它已经固定好了。
The steps outside the main tower had been repaired. The old stones remained, with rough new tiles fitted into their worn centers. On the third step, Clay’s foot automatically avoided a formerly loose stone. Only when he looked down did he see it had been secured.
Dr. T 注意到了。
Dr. T noticed.
“有个老人差点摔倒。后来我让人全部检查了一遍。”
“An old man nearly fell. After that, I had them all checked.”
“我记得你以前说那块石头还能用。”
“I remember you saying that stone would do.”
“我以前说过很多不对的话。”
“I used to say a great many wrong things.”
他说得平静，Clay 一时不知道该如何把口袋里的文件拿出来。
He said it calmly. For a moment, Clay did not know how to bring out the papers in his pocket.
门厅有饭菜味。左边以前储存灯油，如今隔成小房间，门上贴着姓名。一个女人坐在走廊尽头给孩子剪指甲，剪一下，吹一吹，孩子则不停地扭头看岚的宇航服。
Food smells filled the entrance hall. On the left, the old lamp-oil store had been divided into small rooms with names on their doors. At the end of the corridor, a woman clipped a child’s nails, blowing after each snip. The child kept turning to stare at Lan’s spacesuit.
“能飞吗？”孩子问。
“Can you fly?” the child asked.
岚看了看自己沉重的鞋。
Lan looked at her heavy boots.
“在这儿走快一点都难。”
“It’s hard enough to walk fast here.”
孩子失望片刻，又问头盔可不可以借。她说今天不行。孩子母亲向她道歉，岚摇头，说这样问没关系。
After a moment’s disappointment, the child asked to borrow the helmet. She said not today. His mother apologized. Lan shook her head and said it was all right to ask that way.
Dr. T 给几个人介绍，住在这里的多是外围街道断联后搬来的居民。楼下用餐，楼上睡觉，洗衣和热水按时供应。有人正把一盆洗净的萝卜拿进厨房，另一个人追出来说还少了一把刀。
Dr. T explained that most people living here had moved in after losing connections to the outer streets. They ate downstairs and slept upstairs. Laundry and hot water were provided at set times. Someone carried a basin of washed radishes into the kitchen. Someone else followed, calling that a knife was still missing.
Clay 认得里面两张脸。他们也认得他，一个走过来握了握他没受伤的手，说原以为再也见不到。Clay 心里突然一松，随即又觉得这种松快有些难堪。
Clay recognized two faces. They recognized him too. One man came to shake his uninjured hand and said he had thought they would never meet again. Clay felt a sudden relief, then felt ashamed of it.
同一天，有人已把他当成陌生人，也有人只是以为老友来得太晚。
On the same day, some people already regarded him as a stranger. Others merely thought an old friend had come back too late.
餐厅里摆着几张拼起来的桌子。Dr. T 没把他们安排进单独房间，而是让他们和住客一起盛饭。锅里是豆子、根菜和一点肉，另一口锅煮着米。每人先拿一勺肉，吃完还有可以再添。
Several tables had been pushed together in the dining room. Dr. T did not take them to a private room; he had them serve themselves with the residents. One pot held beans, root vegetables, and a little meat. Another held rice. Each person began with one spoonful of meat and could return for more if any remained.
Dr. T 自己盛得少，给一个坐轮椅的男人把碗推近。那人说不够，他便去添，没有说什么营养或份量的道理。
Dr. T took a small portion himself and pushed a bowl closer to a man in a wheelchair. When the man said it was not enough, he fetched more, offering no lecture about nutrition or portions.
伊沃坐下后仍把工具袋放在脚边。岚找到靠墙的位置，头盔搁在膝上，始终没有放远。Clay 看见她盯着桌上那把叉子，过了几秒才拿起来。
Ivo kept his tool bag by his feet when he sat. Lan chose a place against the wall, her helmet on her knees, never far from her. Clay saw her stare at the fork on the table for several seconds before picking it up.
“不习惯？”他轻声问。
“Unfamiliar?” he asked quietly.
“我知道怎么用。”她说，“只是这把很轻。”
“I know how to use it,” she said. “This one’s just very light.”
他们安静吃了一阵。Dr. T 回来坐下时，粥已经凉了一些。他搅了搅，让众人先说今天取回了什么。
They ate quietly for a while. By the time Dr. T returned and sat, his porridge had cooled. He stirred it and asked them to begin with what they had recovered that day.
Clay 把船长的信放到桌子中间。
Clay laid the captain’s letter in the middle of the table.
Dr. T 先看人数，看完闭了下眼睛，才继续往后读。
Dr. T read the head count first. He closed his eyes briefly before continuing.
“我早上派出去的信号没有回应。”他说，“这个好。至少知道他们在外侧。”
“No response to the signal I sent this morning,” he said. “This is good. At least we know they’re outside.”
伊沃指着那两束交叉的灯。
Ivo pointed to the crossing beams.
“但他们不敢回来。主塔的指向不对。”
“But they’re afraid to return. The main tower’s pointing the wrong way.”
“现在的主塔首先保证镇内的连接。”
“Its first task now is to maintain connections inside the town.”
“所以船看不懂。”
“So the ferry can’t read it.”
“是。”
“Yes.”
这次 Dr. T 没有用别的词。他将信放回原处，夹了一块根菜，似乎想等自己咽下去再继续，最后又把筷子放下了。
This time Dr. T used no other word. He replaced the letter and picked up a piece of root vegetable, apparently intending to swallow before continuing. Then he set his chopsticks down again.
“我知道这样不能一直维持。可你们刚才从门口走到这里，看见的每一个人，都得有地方站着。我把灯完全转向海，内侧会发生什么，不能靠希望。”
“I know this can’t last forever. But every person you passed between the entrance and this room needs somewhere to stand. I can’t rely on hope about what happens inside if I turn the light entirely toward the sea.”
伊沃把自己的测量纸铺开。它比餐桌小，边缘还沾着泥，他怕弄脏桌面，底下垫了张餐巾。
Ivo spread out his measurements. The sheet was smaller than the table and still muddy at the edges. Worried about dirtying the surface, he laid a napkin beneath it.
“现在也在断。下周四那次潮以前，外圈几处会碰到一起。你收到过。”
“It’s breaking now. Before next Thursday’s tide, several outer gaps will meet. You received this.”
Dr. T 看着表格，点头。
Dr. T looked at the table of figures and nodded.
“我收到过。也在做补偿。”
“I did. We’re compensating for it.”
“补偿以后有人不记得人了。”Clay 说。
“After the compensation, people forget other people,” Clay said.
邻桌的谈话停了一瞬。Dr. T 低声请他们吃完后到旁边的小屋谈。Clay 想拒绝，却看见刚才那个孩子正盯着他，手里的勺子停在嘴边。
Conversation at the next table briefly stopped. Dr. T quietly asked them to talk in the little room next door after eating. Clay wanted to refuse, but saw the child staring at him, spoon suspended at his mouth.
他收起纸，没有继续。
He gathered the papers and said no more.
小屋以前是茶水间。墙上留着杯子架，下面挂满不同颜色的杯子。有的刻了名字，有的只画一个容易认的小图。桌上铺着一张小镇模型，几盏细灯沿模型边缘排列。玻璃罩内的桥和房子以很慢的速度变化，像有人正在从另一面轻轻挪它们。
The little room had once been the tea room. The cup rack remained on the wall, crowded with cups of different colors. Some bore carved names, others simple, recognizable pictures. A model of the town covered the table, tiny lamps arranged around its edge. Beneath its glass dome, bridges and houses shifted very slowly, as though someone on the far side were nudging them.
岚停在模型前，没伸手。
Lan stopped before the model without touching it.
“它是记录，还是控制？”
“Does it record, or control?”
Dr. T 将椅子拉出来。
Dr. T pulled out the chairs.
“这里这套只记录。真正连接灯区的在楼上。”
“This one only records. The equipment connected to the light sectors is upstairs.”
“你怎么知道它没把同一个错误记两次？”
“How do you know it hasn’t recorded the same error twice?”
他看了她一眼。那不是被冒犯后的眼神，反而像终于听见一个一直在等的问题。
He looked at her without offense, almost as though he had at last heard a question he had been waiting for.
“所以有两个观察口。”
“That’s why there are two observation ports.”
他指向玻璃罩两侧。一个开着，另一个被金属片盖住。伊沃立刻想起什么，看向 Clay。Clay 也记起后街烧黑的第二接槽。
He pointed to opposite sides of the dome. One port was open; a metal plate covered the other. Ivo suddenly remembered something and looked at Clay. Clay remembered the scorched second slot on the back street too.
Dr. T 没有让他们继续看。他将模型上方的防尘布盖好，坐下来。
Dr. T did not let them keep looking. He spread the dustcloth over the model and sat.
“你想问自己的许可。”他说。
“You want to ask about your permit,” he said.
Clay 把副本摊开，推到他面前。
Clay unfolded the copy and pushed it toward him.
“我同意过一次试灯。这里后来写的不是一次。”
“I agreed to one lamp trial. What came after this isn’t one trial.”
“第一次试验出了事故。”
“There was an accident in the first trial.”
“我知道。我在场。”
“I know. I was there.”
Dr. T 用拇指压住纸角。那只手的关节有些变形，Clay 记得事故后包扎过很长一段时间。
Dr. T held down a corner with his thumb. The joints of that hand were slightly deformed. Clay remembered the long weeks of bandages after the accident.
“事故留下的裂缝没有按我们预想的关闭。临时方案成了维持镇子的方法。当时我没有新的选择。”
“The fractures it left didn’t close as we expected. A temporary measure became the means of keeping the town going. At the time, I had no new choice.”
“七年？”
“For seven years?”
“不是七年都毫无进展。”
“It wasn’t seven years without progress.”
“我的通知寄到一间空值班室。买铜接头时你们知道外港地址，续我的签名时不知道？”
“My notice was sent to an empty duty room. You knew the outer-harbor address when you wanted copper connectors, but not when renewing my signature?”
Dr. T 沉默了。
Dr. T was silent.
隔壁有人洗碗，陶瓷碰撞声清脆。Clay 发现自己想把那声音关掉，好让屋里没有任何东西替眼前的人分担沉默。
Someone washed dishes next door, ceramics clinking clearly. Clay found himself wishing he could switch off the sound, leaving nothing in the room to share the other man’s silence.
“这部分是我的责任。”Dr. T 最后说，“我不能拿事故解释那张通知。”
“That part is my responsibility,” Dr. T said at last. “I can’t use the accident to explain that notice.”
“那就把完整记录给我。”
“Then give me the full record.”
“与你本人有关的原始同意和运行变化，我明天给你。其他居民的资料要先遮掉。”
“Tomorrow I’ll give you your original consent and the changes in operation that concern you. The other residents’ details must be redacted first.”
“谁来遮？”
“By whom?”
“档案员可以在场。”
“The archivist can be present.”
Clay 看着他，没立刻答应。
Clay watched him without immediately agreeing.
岚把头盔放在自己脚边。
Lan set her helmet beside her feet.
“我的那份也要。”她说。
“Mine too,” she said.
Dr. T 转向她。
Dr. T turned to her.
“你做过的两次检查都可以看。还有些推断，现在不能当事实给你。”
“You can see both examinations. Some conclusions are still conjecture. I can’t give them to you as facts.”
“就写推断。我会读这两个字。”
“Label them conjecture. I know how to read that word.”
他说了一声好。
He said yes.
伊沃在纸上记下：明天中午，原始同意、续期变化、岚的两次检查，档案员在场。写完推过去，让 Dr. T 看。
Ivo wrote: Tomorrow, noon. Original consent, renewal changes, Lan’s two examinations. Archivist present. Then he pushed the note toward Dr. T to read.
Dr. T 在下面写了自己的名字。
Dr. T signed beneath it.
Clay 没有因这个签名放心。他只是把纸收好。
The signature did not reassure Clay. He simply put the paper away.
“诺拉的事呢？”
“What about Nora?”
Dr. T 轻轻搓了一下右手关节。
Dr. T gently rubbed the joints of his right hand.
“我知道有人出现认知上的缺口。”
“I know some people have developed gaps in cognition.”
“她不是忘记钥匙放哪里。她看着合照，记得那天所有人的事，就是不记得我。”
“She hasn’t forgotten where her keys are. She looks at a photograph of us and remembers everyone else that day. Just not me.”
Dr. T 的目光移到 Clay 脸上，又很快移开。
Dr. T’s eyes moved to Clay’s face, then quickly away.
Clay 看见了。
Clay saw it.
“你以前见过。”
“You’ve seen this before.”
“我见过类似的。”
“Something similar.”
“为什么不告诉我？”
“Why didn’t you tell me?”
“因为还没有把它和每一次分区恢复准确对应。也因为你不在这里。”
“Because we hadn’t matched it precisely to each sector restoration. And because you weren’t here.”
“我不在这里，不是个理由。”
“My not being here isn’t a reason.”
“是。”Dr. T 说，“不是。”
“Yes,” Dr. T said. “You’re right.”
他说完，没有继续请求理解。那让 Clay 更想发火，却又找不到能够当场证明的东西。他把手压在纸上，手心伤口被桌沿顶得发疼。
He did not go on to ask for understanding. That made Clay angrier still, yet he could find nothing he could prove then and there. He pressed his hand onto the paper, the table edge hurting the wound in his palm.
岚忽然问：“如果我想离开观测站，你会拦吗？”
Lan suddenly asked, “If I wanted to leave the observatory, would you stop me?”
“不会。”
“No.”
“如果我不再做检查？”
“If I stopped having examinations?”
Dr. T 看着她，回答比刚才慢了一点。
Dr. T looked at her. His answer came a little more slowly.
“我会告诉你可能错过什么，然后由你决定。”
“I would explain what you might miss, then let you decide.”
“那明天就照这个做。”
“Then do that tomorrow.”
房门外响起敲门声。一个值班的女人探头进来，说楼下热水管又开始响，东面两间房的人不敢用。Dr. T 立刻站起来，向她询问声音从哪里开始，有没有人被烫到。
Someone knocked. A woman on duty looked in and said the hot-water pipe downstairs was making noises again; the people in two east-side rooms were afraid to use it. Dr. T immediately stood, asking where the sound began and whether anyone had been scalded.
Clay 跟着起身，手已经伸向工具袋。伊沃先把袋子拿了起来。
Clay rose too, already reaching for the tool bag. Ivo picked it up first.
“我去。”他说，“你把答应的事先谈完。”
“I’ll go,” he said. “Finish what you promised to discuss.”
Dr. T 停了停，点头，给他指了隔离阀的位置。伊沃又问一句，确认那是最新位置，才跟着女人出去。
Dr. T paused, nodded, and told him where the isolation valve was. Ivo asked once more to confirm that it was the current location, then followed the woman out.
岚走到模型边，借侧面的反光看了一会儿。防尘布没有完全盖住玻璃，里面一段小桥正在轻微颤动。她拿起桌上一只普通手电，照向被遮住的观察口边缘，桥影暂时不动了。手一偏，颤动又回来。
Lan went to the model and watched it in the reflection along its side. The dustcloth had not quite covered the glass. Inside, a small bridge trembled. She took an ordinary flashlight from the table and aimed it along the edge of the covered observation port. The bridge’s image briefly held still. When her hand shifted, the trembling returned.
“只是模型。”Dr. T 说。
“It’s only a model,” Dr. T said.
“我知道。”她回答，“所以不用先让人站上去。”
“I know,” she replied. “So we don’t have to put anyone on it first.”
Clay 看向她。她把手电放回原处，没有要求立即开启任何东西。
Clay looked at her. She returned the flashlight without asking to switch anything on immediately.
伊沃回来时，袖口湿了。问题不大，一只回流阀被杂物卡住。他洗了手，拿走自己的袋子，说外面快起雾，得陪岚回观测站。
Ivo came back with wet cuffs. The problem was minor: debris had jammed a return-flow valve. He washed his hands, took his bag, and said fog was coming in, so he needed to walk Lan back to the observatory.
Dr. T 从篮里拿出剩下的饭，让她带着。岚接过，说谢谢，没有因此撤回自己明天要看记录的要求。
Dr. T gave her the remaining food from the basket. Lan accepted it and thanked him. She did not withdraw her demand to see the records tomorrow.
走到门厅，那个想借头盔的孩子已经睡着了，母亲正把他抱回房间。Dr. T 替她开门，抬手挡住门框，免得撞到孩子的头。
In the entrance hall, the child who wanted the helmet had fallen asleep. His mother was carrying him back to their room. Dr. T opened the door and held a hand against the frame to protect the child’s head.
Clay 等他回来。
Clay waited for him to return.
“如果你答应的记录明天还是只有一部分呢？”他问。
“What if the records you promised are still only part of it tomorrow?” he asked.
Dr. T 看向楼上。
Dr. T looked upstairs.
“你可以自己核对目录。”
“You can check the catalog yourself.”
“我会。”
“I will.”
出了塔门，海上的雾正贴着台阶爬上来。岚走得慢，厚鞋踩在湿砖上不稳。伊沃把手提灯放低，照着每一级边缘。
Outside the tower, sea fog was creeping up the steps. Lan walked slowly, her thick boots unsteady on the wet bricks. Ivo held the hand lamp low, lighting the edge of each step.
岚回头问 Clay，上午有没有空。
Lan turned to ask whether Clay was free in the morning.
“中午看原件。”他说。
“Original records at noon,” he said.
“上午先找一座没人的小桥。不是通人的那种，模型那么大也行。带两个互不相连的灯。”
“Before that, find an empty little bridge. It needn’t carry people. Model-sized is fine. Bring two lights with no connection between them.”
“你想试刚才那一下？”
“You want to try what you did just now?”
“我想知道我看见的，是不是我想看见的。”
“I want to find out whether I saw what was there, or what I wanted to see.”
Clay 点头。
Clay nodded.
三个人在坡道分开。回到面包店时，他没有再去摸门铃的布，直接用钥匙开门。Miso 听见声音，慢慢从炉边爬起来，尾巴扫过地板。
They parted on the slope. Back at the bakery, he left the cloth on the doorbell alone and opened the door with his key. Miso heard him and slowly rose from beside the oven, tail sweeping the floor.
Clay 在柜台上留下一张纸：已回来。明早出门前再说。
Clay left a note on the counter: Back. We’ll talk before I leave tomorrow morning.
然后他坐到窗边，把两份有签名的纸并排放好。七年前那一份把他留在了一件自己不知道的事里；今晚这份，至少不能再被放到空屋里，替另一个人说已经听见。
Then he sat by the window and laid the two signed papers side by side. The one from seven years ago had kept him inside something he knew nothing about. At least tonight’s paper could no longer be left in an empty room to say, on someone else’s behalf, that he had heard.
