The blue stripe led them down, and the facility opened around them like a held breath.
It was half-empty — the diversion had pulled the day shift toward the fire, and the night skeleton crew moved in distant pairs, their boots echoing off concrete. Ethan navigated by fragments: left where the stripe bent, past the cold-storage doors with their frost beards, through a lab with its lights off and its machines sleeping. Every corridor smelled like disinfectant and old fear.
At a junction, the stripe split — blue going left, a faded yellow going right — and Ethan stopped cold. He'd stood here. Five years old, small hand in a bigger one, and the bigger hand had tugged him left, toward the blue, and a voice had said, "Follow the blue, kiddo, the blue's the way back —"
His chest seized. Kiddo. Whose voice was that?
"Ethan." Marlene's hand on his shoulder, steady. "Left?"
"Left," Ethan whispered. "The blue's the way back."
"How much further?" Hale breathed.
"Close," Ethan said. He didn't know how he knew. He just did — the way you know your own house in the dark.
They ghosted past a patrol at a stairwell — four sets of lungs held still in a doorway recess while two guards passed arguing about the fire.
"— saying it's the Fireflies again —"
"Fireflies are dead, man, Denver proved —"
Their voices faded down the corridor. Nobody breathed until the echoes died. Marlene's hand was steady on Ethan's shoulder. Joel's rifle never wavered.
The workup wing doors were white. Everything else in the facility was grey concrete, but these doors were white, like a hospital, like a promise.
The isolation ward was six rooms off a central corridor. Five stood open and empty, stripped bare.
The sixth was locked.
Ethan had the lock open in twenty seconds — spoon-handle years, paperclip months — and the door swung in on a boy curled on a cot, maybe eleven, thin wrists, the dark mark on his forearm. Sedated, half-aware, his eyes finding Ethan's without focusing.
"Hey," Ethan said softly. "Milo, right?"
The boy's eyes widened — his name, in a stranger's mouth, in this place.
"We're getting you out," Ethan said. "Can you walk?"
Milo nodded, slow, and swung his legs off the cot. He stood. He swayed. Joel was there before he fell, one arm around the boy's shoulders, and Milo leaned into him like he'd been waiting years for someone to lean on.
"The harvest list," Marlene murmured, moving to the ward's desk. She found the schedule — and went still. "Nine days. It's all here. Vane's initials on every page."
Ethan looked at the pages. Neat handwriting. Clean hands.
The detention level was two floors down, past the labs, behind a door marked MAINTENANCE that wasn't.
Ethan's fragments went quiet here. He'd never been this deep. This was where they'd kept the adults — the ones who'd fought back, the ones who knew too much.
Six cells. Five empty.
The sixth had a man in it.
He was skeletal, grey-bearded, his hands folded in his lap like he was waiting for something that had stopped coming years ago. But his eyes — when the door light hit them — his eyes were sharp. Soldier's eyes. Nightingale eyes.
Marlene made a sound like she'd been punched.
"David," she whispered.
Ethan couldn't move. Couldn't breathe. The man looked up — and his whole body went rigid, and then he was on his feet, stumbling, catching himself on the bars.
"Ethan?" His voice cracked on the name. "Ethan, is that — is that really —"
"Dad." It came out of Ethan like something torn. He was at the bars, and David's hands were through them — rough, shaking, warm — on his face, and they were both crying, and Ethan — who had died in another life, who had been D-09, who had carried all of it alone — was fourteen years old and held by his father for the first time in nine years.
"I counted," David kept saying, his forehead pressed to the bars. "Every day. I counted every day since they took you, and I told myself —" His voice broke. "I told myself the counting was the same as keeping you. It wasn't. It wasn't, but it's all I had."
"I've got you," Ethan said — and realized David had been saying it too, the two of them trading the words back and forth like a rope. "I've got you, I've got you —"
Hale had the cell open. Joel was checking the corridor. Marlene stood frozen, staring at the cell across the hall.
It was empty. Stripped. But on the wall, scratched into the concrete at eye level, in small precise letters:
MIRA — 12.14
And below it, fresher, the concrete still pale where it had been gouged:
THEY MOVED ME UP. DON'T FOLLOW.
"Mira," Marlene breathed. "She was here. Two weeks ago, she was here."
Ethan turned, David's arm around his shoulders, David's weight leaning on him — and read his mother's words on the wall.
THEY MOVED ME UP. DON'T FOLLOW.
Don't follow. Even now — even scratched into concrete in a cell — she was protecting him. Telling him not to come. And he was here anyway, in her mountain, under her warning, because some things you don't get to choose.
"Up," he said, his voice rough. "Where's up?"
Marlene's face had gone white. "Vane's level. The principal's floor." She looked at him. "She's with them, Ethan. Whoever they are."
The alarm started as they reached the stairs.
Not the fire alarm — a different tone, climbing, urgent. Someone had done a headcount. Someone had found the empty isolation room.
"Move," Hale said.
They moved — Joel half-carrying Milo, Ethan half-carrying his father, Marlene on point with her pistol, up the stairs toward the blue stripe and the tunnel and the mountain's dark throat.
Behind them, boots. Shouts. The facility waking up.
Ahead: the stripe, the vents, the way out.
Ethan ran, and didn't look back.
