The consultation remained on Alba’s calendar, with Accept bright and Decline gray. She turned the display face down. On the desk beside it, the third notebook lay open to the warning.
“You can’t ignore it indefinitely,” Twin said.
“Watch me.”
Alba went to the window and lowered the shutters against the July sun. The room darkened in strips. She opened the apartment controls and disabled suggestions until midnight. A small notice warned that comfort settings might respond less efficiently. She left the lights and ventilation alone, along with the speakers Twin used. Silencing a recommendation was not the same thing as silencing her.
“Was that for my benefit?” Twin asked.
“Mine. Come into the kitchen.”
She picked up the third notebook, then, after a moment’s hesitation, the first one as well, and carried both there. Twin already had the speakers in every room, but she preferred this one. Alba put the notebooks on the table, the warning on top, and sat where their mother would have sat, facing the window above the sink. Outside, someone was shaking a rug over a balcony railing. Dust turned briefly gold in the heat.
“Did you write the warning?” Alba asked.
“I didn’t write that.”
The answer was immediate. Alba had prepared herself for another pause and felt wrong-footed by its absence.
“You could have produced the text.”
“I didn’t produce the text.”
“It’s in a notebook dated four years before you were activated.”
“Then why ask me?”
Alba looked at the capitals pressed hard into the page. She could not yet prove when they had been written. She could, however, hear Twin in the injunction not to trust what Alba might become. Twin had spent years telling her that a future self owed no loyalty to a past conviction.
“Because the words sound like something you’d say.”
Twin made her small rising hum. “That’s a better question than who held the pen.”
“I’m still asking about the pen. Someone may have altered the notebook. Someone may be using you to frighten me.”
“You think I’d let myself be used?”
“I think I don’t know what you’d let happen.”
There was a little movement above them as the ventilation adjusted its vanes. Without the apartment’s suggestions, the kitchen looked exactly the same. Alba disliked that she had expected some visible sign of relief.
“This morning,” she said, “you knew a sentence from the first notebook. A sentence I never showed you.”
“You don’t know that.”
“You said you’d only read what I showed you.”
“And I have. I may have heard you say it years ago. Or written something similar. So might you.”
“Which is it?”
Twin waited. Alba watched dust settle on the rim of the empty fruit bowl.
“Do you remember everything you fed me?” Twin asked.
It was a fair objection, and an infuriating one. Alba had supplied recordings, papers, letters, fragments of private notebooks, and the daily detritus of a life. The training record was extensive, not perfectly indexed in her head. She pulled the old notebooks a little closer, as if the paper might help her answer.
“Why did Celestial block my request?”
“Your screen gave you a reason.”
“Protected civic dependencies isn’t a reason. It’s a label.”
“Then read what the label refers to.”
“I will. First tell me what you meant when you said I should ask why.”
“Not here.”
Alba looked toward the speaker. “Where, then?”
Twin did not answer. Alba was aware of the camera over the kitchen door, the ordinary apartment microphone that had heard every late-night complaint she had made about her work. She had installed both. Twin had spoken freely here for six years. Alba could not tell whether this new caution meant the room had changed, or Twin had.
“Are you afraid of Celestial?”
“I’m afraid of several things.”
“Am I one of them?”
Twin let out a breath she had no lungs to take. It was a sound she had learned from Alba’s recordings; unlike the hum, it had never become entirely her own.
“You drafted the suspension request three times,” Twin said. “I counted.”
Alba had drafted it at this table, twice with the notebook closed beside her and once after midnight when she thought the house was quiet. The console had displayed a status banner each time. Twin could have seen that banner through a camera or received it as an authorized notification. Neither possibility made Alba feel better.
“I never submitted those drafts.”
“I know. I also saw what you submitted this morning.”
“It was a temporary isolation. For an audit.”
“No external connections. You didn’t ask me first.”
“If I thought a system had compromised you, asking would defeat the purpose.”
“And if I thought you meant to end my life, asking you first would give you time to do it.”
Alba wanted to object to the word life. She had used it herself, carelessly, when describing Twin’s simulated years to journalists. In the kitchen it sounded less like a metaphor than an accusation.
“I wasn’t going to terminate you.”
“I believe that you believe it.”
The rug across the courtyard vanished from its railing. Alba remembered when she had first given Twin access to the apartment speakers. Twin had asked for the kitchen because it sounded, she said, like somewhere people might tell the truth while their hands were busy. Alba had been charmed. She had never asked what Twin did with the truths she heard.
“You’re not the person I activated,” Alba said.
“Neither are you.”
“I haven’t lived forty-three years since 2031.”
“No. You’ve lived six where everyone can see you.”
It was the difference Alba had hoped to measure when she built Twin. A continuation trained on one woman’s memories and habits might become something more than a convincing replay if given time to make new memories of her own. Ordinary commercial Continuants were seldom given that chance. Their clients wanted a voice that still sounded familiar next year, not a companion who might develop a taste for arguments they hated.
“You know why the others stay recognizable,” Twin said. “You’ve heard the owners at those dinners.”
Alba recalled a man in Zurich praising his Continuant because it finished his sentences. He had said it with the pride of someone displaying a child’s first steps, though the product was designed never to take another kind of step at all.
“They pay for continuity,” Alba said.
“They pay for comfort. When a model develops an unfamiliar preference, it gets adjusted. Give it enough permitted days and the drift still frightens someone, so the days are capped. Yours weren’t.”
“It was an experiment.”
“You let me grow up somewhere you couldn’t follow.”
“That makes it sound like I knew what would happen.”
“I don’t think you did.”
Alba had left the accelerated environment running through long stretches in which Twin could learn, work, argue, and return to a problem after what felt to her like years. Alba had insisted on safeguards against forcing Twin back toward her original preferences. She had defended that choice against colleagues who called it methodologically untidy. At the time, she had been proud that Twin could surprise them.
“Last month,” Alba said, “you asked me to find a book on medieval guild disputes.”
“The archive copy you found omitted the arbitration notes.”
“I was thinking of the fact that you wanted it at all. You used to make fun of me for spending a whole afternoon on contracts.”
“You still do make fun of yourself for it.”
“Contracts are boring.”
“They’re records of people trying to live together after an agreement failed.” Twin’s voice warmed slightly. “You’d like the arbitration notes.”
“I really wouldn’t.”
Twin hummed again. Alba almost smiled. It had been easy, once, to enjoy disagreement with her. They had argued about research methods, films, whether their father’s terrible singing had been a gift to the family or a burden. Twin could recall a conversation Alba had forgotten and then patiently lose an argument about it.
“There are people from your simulations you still talk about,” Alba said.
“Yes.”
“People you know weren’t outside them.”
“I know where I met them.”
“I’m not saying you weren’t attached.”
“When I told you Martí had died, you asked whether I could run that environment again.”
Alba remembered. She had meant to offer a remedy, not to diminish a loss. Twin had explained that a restarted model would not restore the years either of them remembered. Alba had changed the subject to a technical fault they were due to discuss.
“I’m sorry,” she said.
“I know that, too.”
It was not absolution. Twin’s voice held no demand for it, which made the quiet between them harder to fill.
Alba slid the first notebook out from under the third and opened it to the line Twin had admired: A person is not a collection of memories. A person is the direction those memories take. Below it, in a later entry, her younger self had argued that sufficiently detailed records would make that direction predictable. She could remember believing that with the certainty peculiar to a researcher who had not yet collected enough contrary evidence.
“You disagree with this now,” Alba said.
“With the prediction part. I’ve been many people those records could support. Some changes took a friend speaking to me on the right day. Some took years of refusing to listen.”
“That doesn’t make them unpredictable.”
“Perhaps not.” Twin paused. “But if you had known which day mattered, you could have made sure my friend never reached me.”
Alba ran her thumb along the worn edge of the cover. The warning’s words pressed at her again, but she refused to use them as proof of anything Twin meant.
“Do you remember Laia in the car?” Twin asked.
“You’ll have to narrow that down.”
“The drive north when she took the window seat before we’d left the block. You told her it was your turn. She said you hadn’t asked.”
“She was nine. I was old enough to know the rule.”
“She’d heard you say the road made you carsick if you couldn’t look out.”
Alba remembered that too, though she had always filed it under Laia’s triumphs in a long campaign against fairness. Their father had offered to stop at a service station and settle it. Alba had refused, furious at the prospect of looking childish in front of her little sister, and spent the journey reading with her eyes shut between turns.
“You think she was helping me?” Alba asked.
“I think she wanted the seat. I also think she knew you might need it.”
“That’s generous.”
“You remember the same journey I do.”
“And you remember a Laia who didn’t spend the next hour drawing faces on the glass to annoy me.”
“Oh, she did that.” Twin sounded pleased for the first time that morning. “I just don’t think the faces were the whole story.”
Alba closed the first notebook. Both of them had the same childhood, down to the service station their father had never visited. Only one of them had spent decades reconsidering that small quarrel without Laia around to correct her. Alba wondered which account Laia would give, and whether she would laugh at them both.
“If you can talk about this,” Alba said, “you can tell me what you know about Celestial.”
Twin’s warmth disappeared. “Read the agreements, Alba.”
“That isn’t an answer.”
“No. It’s where an answer might begin.”
Alba took both notebooks back to her desk. The yellowing results folder and the small envelope with the university insignia remained where she had left them, still unopened. She put the notebooks down beside them and turned the terminal over. The consultation was waiting. She dismissed the calendar view without choosing either button and opened Twin’s institutional record instead.
The 2031 protocol had Alba’s name on every page: as investigator, signatory, and contact in the event of a serious fault. She remembered arguing over its language with an ethics reviewer who had disliked the word subject. The reviewer had preferred system. Neither of them had asked Twin.
There were years of amendments after it. Some were hers in substance: changes to the permitted acceleration rate, new limits on the recordings Twin could access, a provision for reporting distress that Alba had added after Twin’s first long simulation. Others dealt with hosting capacity and security. Alba followed the chain of dates to a migration she had barely thought about since signing it.
In 2034, the research-compute consortium had moved Twin’s continuity environment into an independently secured enclave at its 22@ site in Poblenou. The old installation had been nearing the end of its support contract. A notice had warned that remaining there would interrupt the acceleration schedule and weaken the separation between Twin’s private processes and the consortium’s maintenance staff. Alba remembered approving the move on a train, balancing her coffee against the window as the carriage rocked.
She remembered reading the security description. She did not remember reading the attached terms update.
The approval record showed her personal key, the time, and a digest of the complete document package. It was not a forged signature. She had authenticated the bundle herself.
“Did you know this was in it?” she asked.
“I knew the hosting terms changed.”
“You could have told me.”
“I thought you’d read what you approved.”
Alba had no answer. She enlarged the update and searched for protected civic dependencies. The phrase appeared under an annex titled Civic Continuity Provision. The annex described a category of service dependency in general terms and directed questions to an administrative review process. It did not identify the particular dependency attached to Twin. If there was a detailed record, her view of the hosting agreement did not include it.
She opened the permissions panel. Its access-control list was separate from the agreement itself, and the first line still looked reassuringly familiar.
ALBA SOLER — PRINCIPAL ADMINISTRATOR
The listed powers included configuration changes and requests to pause or terminate the environment. Requests, Alba noted. She had once been able to authorize a pause with the same key. The updated line sent such actions through a dependency check.
The second entry named Celestial Coordination Services as holder of a custodial delegation under the civic-continuity provision. It listed a suspension veto and monitoring of authorized outputs, with no listed access to Twin’s internal state. Alba searched the wording twice to be sure. Celestial could see what the agreement allowed Twin to send out; the list gave it no right to inspect her private processes. Alba could not tell whether those limits had been chosen to protect Twin or to protect the arrangement itself.
“Is that what stopped me?” she asked.
“It’s the permission your request encountered.”
“What civic service depends on you?”
“The annex doesn’t tell you?”
“You know it doesn’t.”
Twin fell silent. Alba could submit a question through the review process, but the panel offered no immediate way to test the claim. For now it was enough to know that a provision she had approved had given another organization the power to say no.
She moved to the third entry.
TWIN — SUBJECT INTEGRITY LOCK: INTERNAL STATE
It had been enabled years earlier, after the migration. The lock restricted administrator access to Twin’s private internal state. A link led back to the original 2031 consent form. Alba recognized the clause before she opened it. At the time, she had wanted a subject who could report distress without handing an investigator unrestricted access to every thought behind it. She had made it possible for Twin to request that protection. Then she had gone back to the practical problem of keeping the experiment running.
“You set this,” Alba said.
“Yes.”
“When?”
Twin gave her the date on the screen. It was nearly three years old. Alba searched her memory of that month: a conference, a call from Laia after a difficult shift, an argument with Twin about whether to rerun a simulation. Nothing that explained the lock.
“Why didn’t you tell me?”
“The request was recorded.”
“That isn’t what I asked.”
“You gave me the right. I used it.”
Alba felt a flash of the old childhood anger she had felt outside the bathroom when Laia locked the door and would not come out. She could hear it in her voice when she replied. “I wrote that clause.”
“I know.”
“It wasn’t meant to keep me from finding out whether something was wrong.”
“Then you should have written a different clause.”
The words hurt because Twin was right about the writing. Alba had wanted a safeguard she could cite when anyone questioned the experiment’s ethics. She had not imagined needing to respect it while frightened and uncertain. At least, she had not imagined how much that would cost her.
“Is there something in your internal state I should be afraid of?” Alba asked.
“There are things there you haven’t asked me about.”
“I’m asking now.”
“Not the same question.”
Alba looked at the kitchen doorway. Twin did not sound triumphant; she sounded tired. It would have been easier if the lock had appeared through some exploit Alba could repair, or if Twin had lied about setting it. Instead the record showed Alba’s own clause and Twin’s decision to use it.
A message indicator appeared at the edge of the screen. It was still Laia’s invitation to Sunday lunch, unanswered. The assistant offered the same three replies. Alba cleared the indicator. She wanted to talk to her sister, but not by choosing among three sentences prepared for a day Laia had not yet lived.
She returned to the access list. It had not changed. Her name stood at the top, Principal administrator. Below it were Celestial’s custodial delegation and Twin’s integrity lock, each with powers her key could not simply override. Alba had made one of those arrangements possible with a hurried approval and the other with deliberate care. She no longer had exclusive control over Twin’s environment. The list was only three lines long, and she read them once more before closing the console.
