The moment the door opened fully, the room stopped being a room.
It became a decision.
Ethan felt it hit him first—before sight, before sound. Like something inside the air had shifted its opinion about him and was now finalizing the result.
The space tightened.
Not around his body.
Around his identity.
Lina was still inside the doorframe, but now she wasn't just trapped.
She was being used as structure.
Her shape held the edges of the opening together like a hinge that refused to break.
Her eyes locked onto Ethan.
This time, there was no confusion in them.
Only urgency.
"…Ethan…" she whispered.
But the voice cracked halfway through again.
And something else answered through her mouth immediately.
Soft.
Patient.
"You keep trying to separate what the house has already merged."
Ethan's fists tightened. "Stop speaking through her."
A pause.
Then—
The voice responded gently:
"She is speaking through us too."
The walls shifted.
Subtly at first.
Then all at once.
The room widened sideways, revealing layers that should not have existed—like reality peeling back to show older versions of itself underneath.
Ethan stepped back instinctively.
The younger Ethan moved beside him.
Calm.
Too calm.
"This is the point where most of you stop resisting," he said.
Ethan shot him a sharp look. "Most of me?"
The younger Ethan didn't answer directly.
Instead, he looked at the door.
At Lina.
At the corridor behind her.
"You're not the first version to reach her like this."
Ethan's stomach dropped. "What are you talking about?"
A faint sound came from inside the doorway.
Like pages turning inside water.
Lina's voice broke through again.
Stronger this time.
Desperate.
"…Ethan, listen to me properly—"
The voice cut in immediately.
Not loud.
Not aggressive.
Just certain.
"He will not listen properly."
The corridor behind Lina flickered.
And Ethan saw something impossible:
Other versions of himself standing inside it.
Still.
Watching.
Some with wounds.
Some without faces.
Some already partially dissolved into the walls.
All of them looking at him like he was the newest attempt.
Ethan staggered back. "No… no, that's not real."
The younger Ethan finally turned to him.
And for the first time—
There was something like pity in his expression.
"It's not a memory room," he said quietly.
"It's a selection room."
Ethan froze. "Selection for what?"
The door creaked open wider.
And Lina's fingers dug into the frame harder, as if trying to hold the structure of reality together through pain alone.
Her voice came out sharp now.
"Ethan—if you step in, it will decide what you are!"
Ethan hesitated.
Just for a fraction of a second.
And that hesitation changed everything.
The room reacted instantly.
The floor beneath him softened slightly.
Not collapsing.
Accepting.
The walls leaned in closer.
The corridor behind Lina extended outward like a lung expanding.
The other Ethans inside it shifted.
Not moving.
Updating.
The voice behind Lina spoke again, quieter now.
Almost satisfied.
"Decision detected."
Ethan's breath quickened. "No—wait—what does that mean?!"
The younger Ethan stepped back slowly.
That alone made Ethan's blood run cold.
Because the younger Ethan had never stepped back before.
Inside the door, Lina screamed—
Not from pain.
From realization.
"…Ethan, don't let it label you—!"
Too late.
The corridor behind her blinked.
And something inside the house spoke for the first time without using any voice at all.
A single concept formed directly inside Ethan's mind:
DEFINE: ETHAN
The air stopped.
The walls stopped.
Even Lina froze mid-struggle, eyes widening in terror.
The other Ethans in the corridor turned their heads at once.
Synchronized.
As if they had been waiting for this command since the beginning.
Ethan felt his body go cold.
"No…" he whispered. "No, I'm me."
The house did not argue.
It simply began the process.
The room darkened.
And one by one—
The versions of Ethan inside the corridor began walking forward.
Not toward Lina.
Not toward escape.
Toward him.
The younger Ethan spoke softly, almost apologetic:
"You were always going to reach this step."
Ethan turned sharply. "What step?!"
The younger Ethan looked at him.
And said the worst possible thing in the calmest voice:
"The moment the house decides which version survives."
The first alternate Ethan stepped through the doorway.
And smiled.
Just slightly.
Like he already knew the outcome.
Lina screamed again from inside the frame—
But her voice was swallowed halfway.
Not by darkness.
By classification.
And the room began to choose.
