The phone buzzed in her pocket.
Celine didn't pull it out right away. She was still watching the woman with her face walk into the glass tower across the street, still trying to map the impossible onto something that made sense. The cafeteria behind her smelled like burnt coffee and dish soap. Her hands were shaking.
The phone buzzed again.
She glanced down. Unknown number. A text.
**You're outside the north entrance. Purple jacket. Stolen phone. Smart move, terrible posture.**
Celine's stomach dropped. She looked up, scanning the street, the scaffolding, the tinted office windows. Nobody was watching her. Everybody was watching her.
Another text.
**Relax. I'm not with them. You want answers? Check your old intranet account. Access code: BW-73-SUNDOWN. Then delete this thread.**
She typed fast. **Who is this?**
Three dots. Then:
**Someone who knows what you forgot.**
The thread disappeared.
Celine stared at the screen. Her pulse was hammering in her ears. BW-73-SUNDOWN. She didn't recognize it. But the phone in her hand still had Chen Lin's login cached in a dozen apps, including the Vault Bio VPN client.
She opened it. Typed in her old email. The system asked for two-factor. She didn't have her old device. But there was a backup option: security question.
**What was the code name of your first major product pilot?**
Her fingers hovered. She didn't remember a code name. She didn't remember most of last year. Just the lake. The burn in her lungs. The cold.
She typed: **Blackwater.**
The screen blinked. Access granted.
Her breath caught. She was in.
The intranet loaded. Her old dashboard was still there, archived under FORMER PERSONNEL. She opened it. Most of the files were grayed out, permissions revoked. But one folder sat at the top, marked RESTRICTED ACCESS ONLY. The timestamp read: 2:17 AM, four days ago. Someone had added her back to the share list.
She tapped it.
The folder name was **Blackwater Human Trial / Volunteer Records / SEALED.**
Her mouth went dry.
She opened the first file. A consent form. Standard legalese, neural-interface trial, assumption of risk, right to withdraw. The volunteer signature was a clean digital loop.
She scrolled down.
The second file was a video. Thumbnail showed a sterile white room, a medical chair, electrodes. A woman sitting in the chair, older, maybe sixty, with short gray hair and a calm smile. The timestamp read eighteen months ago.
Celine tapped play.
The woman on screen looked at the camera. "This is Dr. Evelyn Zhao. Volunteer One. Blackwater trial, session one. I'm proceeding of my own volition. No coercion. Let the record show I designed half of this."
Celine's hand went numb.
That was her mother.
Her mother had been dead for two years. Cancer. That's what they told her. That's what she remembered. A hospice room. Morphine. A long goodbye.
But here she was. Alive. Strapped into a neural chair with Vault Bio's logo on the wall behind her.
The video kept playing. Her mother's voice was steady. "If this works, we're looking at full memory indexing within six months. If it doesn't, well. Someone has to go first."
A man's voice off-screen. "Dr. Zhao, we can still use the primate data for another quarter. You don't have to—"
"I'm not waiting another quarter. Start the sequence."
The video cut.
Celine's chest felt tight. She opened the next file. Another consent form. This one had a dozen signatures. Volunteers Two through Thirteen. None of the names meant anything to her. But at the bottom of the page, under PRINCIPAL INVESTIGATOR, there was a signature she recognized.
Hers.
Her hand. Her loop on the capital C. The date was sixteen months ago.
She scrolled faster. More files. Incident reports. Seizure. Cerebral edema. Volunteer Five unresponsive. Volunteer Eight declared dead on site. Volunteer One—status unknown, removed from trial facility by family proxy.
Family proxy.
She opened the last file. A scan of a handwritten note on Vault Bio letterhead.
**Per COO Zhao: if I go under, keep the trial running. The interface works. We just need better containment. Don't let them shut it down. I didn't come this far to stop now.**
The handwriting was shaky but unmistakable. Her mother's.
Celine sat back against the cafeteria wall. Her throat burned. She couldn't breathe right. Thirteen people. Her mother. A trial she didn't remember approving. A trial she signed off on.
The phone buzzed.
Another text. Same unknown number.
**You done reading?**
She typed back, hands shaking. **What the hell is this?**
**That's what you built. That's what they erased. You drowned in the lake because someone wanted you gone before you could pull the plug. Or maybe because you wouldn't.**
She stared at the screen.
**Who are you?**
Three dots. Then:
**Diver. I was there when they pulled you out. I'm the one who copied these files before they scrubbed the servers. And I'm the only one who knows the woman wearing your face is Volunteer Twelve.**
Celine's vision blurred. Volunteer Twelve. She opened the consent form again. Scrolled down the list. There. Mira Soh. Age twenty-nine. Neural engineering PhD candidate. Signed up four weeks after Volunteer One.
Four weeks after her mother.
Another text.
**You want sunrise? You want to know why you're still breathing? Meet me at the south pier. Midnight. Don't trust that face. She's not trying to steal your life. She's trying to burn it down. And you're the only one who can stop her.**
Then:
**Or let her. Your call.**
The thread disappeared again.
Celine sat there, staring at the empty screen. The cafeteria was closing. Someone was stacking chairs. She could hear the hiss of the espresso machine shutting down.
Her mother's face was still frozen on the phone. Volunteer One. Calm. Certain. The woman who taught her to code. The woman who told her to build things that mattered, no matter the cost.
The woman who went into that chair knowing she might not come out.
Celine closed the video. Cleared the cache. Deleted the VPN client. She stood up, legs unsteady, and walked out into the night.
The south pier was ten blocks away. She had six hours.
She didn't know if she'd go. She didn't know if she wanted the rest of the answer.
But the phone was still warm in her pocket. And somewhere in this city, a woman with her face was walking into board meetings, signing off on budgets, smiling at investors.
A woman who survived what her mother didn't.
Celine started walking.
