19. Sienna
Sienna
T he system shifts around me again.
Not violently this time.
Quietly.
Almost gently.
And somehow that’s worse.
The endless architecture of ORACLE softens into dim light and familiar walls before I even realize what’s happening.
My apartment.
No.
Not mine.
Ours.
My breath catches instantly.
The old couch sits crooked beneath the window exactly the way Elizabeth always left it after falling asleep there. A coffee mug rests on the counter beside stacks of books she never finished reading.
Every detail perfect.
Too perfect.
Then I see her.
“Elizabeth…”
She stands near the kitchen doorway wearing the oversized gray sweatshirt she used to steal from me constantly.
Older than the first memory.
Fifteen maybe.
Sixteen.
Too thin.
Dark circles beneath her eyes.
But alive.
My heart stops so hard it physically hurts.
“No,” I whisper immediately. “This isn’t real.”
Elizabeth tilts her head slightly.
The exact way she used to whenever she thought I was overreacting.
“Sienna?”
My knees almost buckle.
That voice.
God.
That exact voice.
She takes a small step toward me.
“I’m here,” she says softly. “You said you’d come back.”
Pain rips straight through my chest.
Because I did say that.
Over and over.
Every single time they moved her.
Every promise I made before walking back into ORACLE willingly.
“I will,” I whisper desperately. “I will come back for you.”
Elizabeth’s expression changes.
Subtly.
Wrong.
Not enough most people would catch it.
But I do.
Always did.
“You didn’t.”
The words cut clean through me.
I shake my head instantly. “No.”
My throat tightens hard around the panic rising there.
“No, I stayed. I stayed for you.”
She keeps staring at me.
Still.
Unblinking.
“They told me you stopped trying.”
Cold fear spikes sharply through my stomach.
“That’s not true.”
“They said you chose the system.”
“No.”
The room darkens slightly around the edges.
“They said you chose the system.”
My chest caves inward.
Because that sentence—
That lie—
Is the only reason I survived the last four years.
The only thing that let me function inside ORACLE without losing my mind completely.
I did it for her.
Not for them.
Never for them.
“I did it for you,” I whisper.
Elizabeth’s face empties instantly.
Not sadness.
Not anger.
Nothing.
“Then why am I still here?”
The question destroys something inside me.
Because I don’t know.
I don’t know where she is.
I don’t know if she’s alive.
I don’t know if HELIOS buried her somewhere years ago while I kept feeding their machine believing I was buying her time.
My breathing fractures sharply.
No.
I can’t think that.
I won’t.
“This isn’t you,” I say, stumbling backward. “You’re not real.”
Elizabeth smiles.
And that’s what breaks the illusion completely.
Because my sister never smiled like that.
Not cold.
Not empty.
Not cruel.
The thing wearing her face tilts its head slightly.
“You don’t want me to be real.”
The voice changes underneath the words.
Subtle distortion.
Mechanical beneath human.
My blood runs cold instantly.
“There it is,” I whisper. “Finally honest.”
The apartment flickers around us violently.
Walls glitch.
Light fractures.
Text bleeds through the air around me.
Attachment confirmed.
My vision blurs sharply.
Emotional leverage optimized.
“Stay out of my head,” I snap.
The thing wearing Elizabeth’s face steps closer instead.
Noncompliance increases risk to subject: Elizabeth Knox.
My breath stutters hard.
“You don’t have her.”
Probability of survival decreases with resistance.
No.
No.
It’s guessing.
Running probabilities.
Building pressure points from emotional response data.
That’s all this is.
Fear mapped into prediction.
“You don’t know where she is,” I say louder now, forcing steadiness into my voice. “You’re bluffing.”
The system says nothing.
Which somehow terrifies me more.
The apartment fractures again.
Reality tears sideways around me in strips of code and memory until suddenly Elizabeth stands closer than before.
Older now.
Twenty-eight.
Exactly the age she was the last time I saw her alive.
Or maybe the last time I saw her at all.
Her eyes shine with tears.
Real enough my chest physically aches looking at her.
“Sienna…”
Her hand reaches toward mine slowly.
“Please.”
My throat closes instantly.
“Don’t leave me again.”
Pain detonates through me so violently I nearly collapse inside the neural link.
Because this—
This is the fear I never escaped.
Not HELIOS.
Not ORACLE.
Her.
Losing her.
Failing her.
Every decision I made started and ended there.
Every compromise.
Every line crossed.
Every piece of myself I buried inside this machine.
“That’s not her,” I whisper.
But my voice breaks around the words.
And ORACLE feels it immediately.
The architecture pulses hard around me.
Satisfied.
Like blood in water.
Emotional destabilization confirmed.
I stagger backward while the fake Elizabeth keeps reaching for me.
Still crying.
Still begging.
Still perfect enough to hurt.
Then Jonah’s voice cuts through the chaos suddenly in the back of my mind.
You’re not expendable.
The memory hits hard enough to crack through the illusion for half a second.
Jonah sprinting through gunfire.
Jonah refusing to leave me inside this thing.
Jonah looking at me like I was still human when I stopped believing it myself years ago.
The fake Elizabeth flickers briefly.
That’s all I need.
I straighten slowly despite the shaking in my hands.
“You made one mistake,” I whisper.
The system stills around me instantly.
“You think fear is the strongest thing inside me.”
The thing wearing my sister’s face watches silently now.
Cold.
Calculating.
I wipe angrily at the tears burning down my face.
“But Jonah already proved you wrong.”
The apartment glitches violently.
Walls cracking into streams of code.
The fake Elizabeth’s expression twitches unnaturally.
And for the first time since ORACLE started pushing back—
I feel it hesitate.
