The first frame is a concrete room.
No windows. Medical cart in the corner. Camera angle says ceiling mount, institutional gray. The timestamp reads three years ago, two months before Celine's supposed drowning accident.
Her mother is sitting in a folding chair.
Celine's hand goes numb on the trackpad.
Evelyn Zhao. Silver bob, tailored blazer, the same slim reading glasses she wore to every board meeting. She's smiling at someone off-camera. Relaxed. Excited, even.
Celine hasn't seen her alive in three years.
The angle cuts. Now there's a second chair. A younger woman in scrubs adjusting an IV stand. And standing behind the camera rig, arms crossed, tablet in hand—
Celine.
Or the woman who used to be Celine.
Same hair. Same posture. But the expression is different. Sharper. Clinical. She's watching her mother the way you'd watch a test subject.
"Ready when you are, Dr. Zhao," Old Celine says.
Her mother nods. "Let's not waste time."
The nurse steps in. Swabs the inside of Evelyn's forearm. Slots in the IV needle. Evelyn doesn't flinch.
"Interface sequence loaded," someone says off-screen. Male voice. Celine doesn't recognize it. "Activation in sixty."
Old Celine taps her tablet. "Vitals?"
"Stable. BP one-twenty over seventy-five. Heart rate sixty-two."
"Good." Old Celine moves closer to the chair. Looks down at her mother. "Any nausea? Vertigo?"
"I'm fine, Celine." Evelyn's voice is steady. Warm, even. "Stop fussing."
"You're the primary."
"I volunteered."
"That doesn't mean—"
"It means exactly that." Evelyn reaches up, squeezes her daughter's wrist. "If this works, we rewrite the entire sector. If it doesn't, I'd rather it's me than some grad student with a family."
Old Celine pulls her hand back. "Thirty seconds."
The nurse steps out of frame. The countdown starts. Celine can hear it in the background, a flat digital chime every five seconds.
Evelyn closes her eyes.
The chime stops.
For a moment, nothing happens.
Then Evelyn's shoulders lock. Her head tilts back. Not violent. Just—sudden. Like someone yanked a wire taut.
"Vitals spiking," the off-screen voice says. "Heart rate ninety. One hundred. One-ten."
"Expected," Old Celine says. She's still watching the tablet. Not her mother. "Neural load is parametric. She's integrating."
"BP one-forty over ninety."
"Still within threshold."
Evelyn's breathing changes. Shallow. Fast. Her hands grip the armrests.
"Mom?" Old Celine finally looks up.
Evelyn doesn't answer.
"Dr. Zhao, can you hear me?"
Nothing.
"Heart rate one-thirty. Oxygen saturation dropping. Ninety-two percent."
"Shutdown sequence," the nurse says, stepping back into frame. She's reaching for the IV line.
"No." Old Celine's voice cuts flat. "We don't have another primary cleared for a month. Let it stabilize."
"She's hypoxic—"
"She's integrating."
"Celine—"
"I said no."
The nurse freezes.
Evelyn's mouth opens. A thin sound comes out. Not words. Just air.
And Old Celine stands there. Tablet in hand. Watching.
The oxygen saturation number drops. Ninety. Eighty-eight. Eighty-five.
"Manual override," the male voice says. "Now."
Old Celine doesn't move.
"Celine, for fuck's sake—"
She taps the tablet. Once.
The countdown reverses. The chime starts again. Evelyn's body jerks forward. She gasps. Coughs. Her hands shake on the armrests.
The nurse is already at her side, pulling the IV, checking her pulse.
Evelyn looks up. Her face is pale. Sweaty. But she's smiling.
"I saw it," she whispers.
Old Celine crouches down in front of her. "Saw what?"
"The map. The whole map. Celine, it works."
Something flickers across Old Celine's face. Not relief. Not joy.
Satisfaction.
"Good," she says. "Then we go to full trial next week."
The footage cuts.
Celine sits back. Her chest is tight. Her hands are cold.
She wants to stop. She wants to close the laptop and throw it in the trash and walk out of this apartment and never think about Blackwater again.
But she doesn't.
She clicks the next file.
This one is shorter. Same room. Different date. Two weeks later.
Evelyn is back in the chair. But this time there are five other people. Three men, two women. All in identical medical gowns. All sitting in a row.
Old Celine is standing at the front. Holding a tablet. Talking.
"—minimal side effects in the primary trial. Dr. Zhao experienced temporary hypoxia but full cognitive recovery within six hours. Neural mapping exceeded projection by forty percent. We're cleared for Stage Two."
One of the men raises his hand. "What's the dropout protocol?"
"There isn't one."
Silence.
"You signed the waiver," Old Celine says. "You knew the terms."
"I thought that was legal boilerplate."
"It's not."
The man looks at Evelyn. "Dr. Zhao?"
Evelyn nods. "The interface requires full integration. If we abort mid-sequence, the neural damage is permanent. It's all or nothing."
"And if we say no now?"
"Then you leave." Old Celine's voice is flat. "And you don't come back."
The man stands. Walks out.
No one else moves.
"Anyone else?" Old Celine asks.
No one answers.
"Good. We start in ten minutes."
The footage cuts again.
Celine's throat is dry. She doesn't remember any of this. Not the room. Not the volunteers. Not the waiver.
She clicks the third file.
This one has no date. No timestamp. Just a black screen and audio.
Evelyn's voice.
"If you're hearing this, I'm already gone."
Celine stops breathing.
"I don't know if it'll be the interface or something else. But I know I won't make it to the end of this project. I've seen the math. The neural load is cumulative. Every session degrades another percentile of synaptic function. By the time we hit full integration, I'll be a vegetable or dead."
A pause.
"I'm doing it anyway."
Another pause. Longer.
"Celine, if you're listening—and I hope you are—you need to finish this. Not for me. Not for Vault. For everyone who comes after. The interface is the only way forward. You know that. I know that. The cost is irrelevant."
Evelyn's voice cracks.
"I'm proud of you. I've always been proud of you. Don't let them shut it down. Don't let them waste what we've built."
The audio cuts.
Celine stares at the screen.
She wants to cry. She wants to scream. She wants to reach through the laptop and grab her mother and shake her and ask her why the fuck she thought any of this was worth it.
But her mother is dead.
And Celine killed her.
She closes her eyes. Her hands are shaking.
She clicks the next file.
The title makes her stop.
DIVER—DON'T TRUST ETHAN.mp4
Her finger hovers over the trackpad.
She clicks it.
The screen stays black.
