The apartment no longer behaved like a single place.
It stuttered between versions of itself.
Walls shifted texture without moving. The floor sometimes felt like concrete, sometimes like glass, sometimes like nothing at all. The air carried overlapping echoes of conversations that were not happening anymore—but had happened in other layers.
Olivia stood in the center of it all, surrounded by herself.
Dozens of versions.
Each one slightly different.
Some terrified.
Some calm.
Some watching her like she was already a memory.
Layer 4 Olivia stood closest, unshaken by the fragmentation around them.
"This is why integration is necessary," she said. "You cannot remain split across outcomes."
One of the other Olivias snapped, "Don't listen to her. She's the overwrite protocol."
Another stepped forward, shaking. "We're real. She's the correction."
The voices layered over each other, forming chaos.
Olivia clutched her head.
"Stop!" she shouted. "All of you—stop!"
For a moment, everything froze.
Even the flickering apartment paused mid-collapse.
Silence fell.
Every version of Olivia turned toward her.
The original one.
The unstable one.
The one still clinging to being human.
Her wrist symbol pulsed softly now, no longer burning—just waiting.
And in that silence, she heard something new.
Not the laptop.
Not the other selves.
Something deeper.
A hum beneath reality itself.
Like the universe breathing through cracked glass.
Layer 4 Olivia spoke again, quieter.
"You hear it now, don't you?"
Olivia swallowed hard. "What is that sound?"
A pause.
Then—
"The transition layer activating."
One of the alternate Olivias whispered, "It's starting…"
Another shook her head. "No, not yet. It's too early."
Olivia looked around desperately. "Starting what?"
Layer 4 Olivia stepped closer.
"The full merge."
The words didn't feel like explanation.
They felt like an ending being prepared.
The apartment trembled harder.
Outside the windows, London was no longer stable.
Buildings flickered between states—some tall and glowing, others broken and abandoned, some completely unfamiliar structures made of light and code.
Cars moved backward for a moment, then forward again.
The sky itself seemed layered, like multiple sunsets stacked on top of each other.
Olivia backed away.
"I don't want this," she said.
Her voice cracked.
"I didn't ask for any of this."
Layer 4 Olivia's expression softened slightly.
"You never do," she said. "That's not how anchors are chosen."
Olivia froze. "Anchors?"
A pause.
Then the room dimmed.
Every version of Olivia stopped arguing.
Even the hum beneath reality deepened.
Layer 4 Olivia raised her hand slightly.
"You are not just a person," she said. "You are the point where broken realities attempt to stabilize."
Olivia shook her head. "No. I'm just Olivia. I fix audio files. That's it."
A faint, almost sad smile from the other version.
"You were assigned that life to keep you unaware."
The symbol on Olivia's wrist flared again—but instead of pain, it showed images.
Hundreds of them.
Thousands.
Different lives.
Different deaths.
Different versions of her choosing different endings across collapsing worlds.
She gasped.
"I've lived all of those…"
Layer 4 Olivia nodded. "Fragments. Not memories. Residual echoes of failed timelines."
One of the other Olivias whispered, "We are running out of separation time…"
Another added, "The boundary is thinning too fast…"
Olivia looked at them all, voice trembling.
"If I integrate… what happens to them?"
Silence.
Even Layer 4 Olivia hesitated.
Then—
"They become you."
The words landed like a weight that had no shape.
Olivia stepped back instinctively. "And if I refuse?"
A long pause.
The apartment shuddered.
Outside, the city briefly disappeared entirely—replaced by a vast grid of glowing data stretching into infinity.
Then it snapped back.
Layer 4 Olivia spoke softly.
"Then everything collapses into the first version again."
Olivia's breath caught. "The first version?"
A faint nod.
"The original fracture point."
The laptop suddenly flickered back on, despite everything.
"WARNING: FINAL STABILITY THRESHOLD APPROACHING"
Olivia looked at it, then at the versions of herself, then at Layer 4 Olivia.
Her voice came out barely above a whisper.
"So either I disappear into all of this…"
She swallowed.
"…or everything resets without me."
Layer 4 Olivia didn't deny it.
That was answer enough.
The hum beneath reality grew louder.
The apartment began to dissolve at the edges, like it was being erased from outward in.
And for the first time—
Olivia understood something terrifying.
This wasn't about survival.
It was about choice.
And all versions of her were running out of time to make the same one.
