THE ECHO PROTOCOL

The first time Maris died, she woke up still tasting copper.

It wasn’t blood—there was no blood in the rethread chamber, no wounds on her body, no bruises on her ribs where the impact should have shattered bone. The copper taste lived somewhere else, in the seam between memory and sensation, where the brain insisted on finishing what the world had interrupted.

Her eyes opened to a ceiling of matte white, the kind designed to be forgettable. The light was soft, diffuse, engineered not to cast shadows that could suggest corners. Nothing here wanted to be remembered.

A voice spoke from the wall. Calm. Uninflected. Intimately close.

“Welcome back, Maris Calder.”

She tried to swallow. Her throat worked as if it had never done this before.

“Your last continuity marker is being restored,” the voice continued. “Please remain still.”

Maris moved anyway. Not much. Just enough to prove she could.

Pain didn’t come. Instead there was a wrongness—a blankness in the muscles like a song missing its bassline. She lifted her hand into view. Pale skin. Clean nails. A thin scar at the base of her thumb that she’d had since childhood. It was there, exactly where it should be.

That should have reassured her.

It didn’t.

She remembered falling.

Not metaphorically. Literally—weightless for half a heartbeat as the platform gave, the safety rail snapping like a cheap promise, the wind roaring up the maintenance shaft. She remembered the flash of yellow hazard paint rushing past and the inexplicable thought, absurd in its clarity:

This is going to hurt.

Then nothing.

Now: white ceiling. Breath. A voice that knew her name.

The door slid open with a pneumatic sigh, and a woman in slate-grey scrubs stepped inside, tablet tucked beneath her arm. Her badge read DRA. LENI KOVAL in crisp black.

Leni’s face had the tired kindness of someone who repaired disasters for a living.

“Hey,” Leni said. “You’re doing great. Don’t sit up yet.”

Maris stared at her. The words arrived before caution could stop them.

“How many times?”

Leni’s expression didn’t change, but something behind her eyes did, like a screen dimming.

“How many times have I died?” Maris insisted.

Leni exhaled. “This is your second rethread.”

Second. So the copper taste belonged to the first time.

Maris felt a laugh rise and die in her throat. “You say that like it’s normal.”

“It’s not normal,” Leni said gently. “It’s… managed. You signed the consent stack. You’re a Continuity Participant. That’s why you’re alive at all.”

“I’m alive,” Maris repeated, testing the word. “Or you made a copy.”

Leni’s mouth tightened. “We don’t use that language.”

Maris turned her head toward the mirror panel on the wall. Her reflection turned with her, perfectly aligned. Same eyes. Same small freckle near the left brow. Same faint line between the lips from a lifetime of biting back words.

If she was a copy, she was a cruelly accurate one.

Leni tapped the tablet. “I’m going to run a quick orientation and then we’ll get you back to your room.”

“Orientation,” Maris echoed. “For being dead twice.”

Leni gave her the version of a smile that meant please don’t make this harder. “For continuity.”

The wall display flickered on. A logo formed: a circle split by a horizontal line, like an eye half-closed. Beneath it: ECHO PROTOCOL.

“Your continuity index will stabilize within six hours,” the voice from the wall said. “During this time, you may experience: sensory echoes, temporal dissonance, transient déjà vu, and emotional mismatches.”

Maris stared. “Emotional mismatches.”

Leni’s eyes didn’t leave her face. “You might feel afraid of things you can’t explain. You might miss people you’ve never met. It passes.”

Maris’s mouth went dry. She remembered a hand gripping hers—hard—someone shouting her name.

But no name came with the memory. No face. Just the sensation of fingers digging into her skin like an anchor.

“Who pulled me?” she asked.

Leni paused too long. “There was no one in the shaft.”

Maris felt cold spread across her ribs. “I remember someone.”

“That can happen,” Leni said quickly. “The brain tries to complete the narrative. Falling is—”

“No,” Maris said. Her voice sharpened. “It was real.”

Leni softened her tone. “Maris. Your mind is rethreading. It’s stitching. Sometimes it stitches in the wrong color.”

Maris turned away from Leni, away from the mirror, toward the clean emptiness of the ceiling.

If her mind was stitching, then something had torn.

“What’s my continuity marker?” she asked.

Leni’s fingers tightened on the tablet. “Your anchor memory.”

“What is it.”

Leni hesitated, then read: “A beach. Dusk. A metal bracelet on your wrist. Someone laughing behind you.”

Maris blinked.

A beach at dusk.

She saw it instantly: wet sand turning the color of bruises, the ocean rolling in with a low, steady thunder. She felt the bracelet—cool, ridged, heavy. She heard laughter—warm, close.

And she knew, with an ache that startled her, that the laughter belonged to someone she trusted.

“Who?” Maris asked.

“That’s not in the marker,” Leni said, too smoothly. “Markers are sensory, not relational.”

Maris’s heart began to beat faster, as if it could outrun the unease. “That’s convenient.”

Leni’s jaw tightened. “It’s safer.”

“Safer for who?”

Leni didn’t answer.

The wall display dimmed. A line of text appeared:

PLEASE CONFIRM: DO YOU CONSENT TO CONTINUITY RESTORATION?

Maris stared at the question like it was a trap disguised as a choice.

“I already consented,” she said.

“Yes,” Leni replied. “But post-rethread you have the right to withdraw. If you withdraw, we terminate restoration at your last stable marker. You’ll keep what you have now, and you’ll never rethread again.”

Maris’s palms went slick.

If she withdrew, she’d keep this half-stitched self. The beach, the bracelet, the laughter with no face.

If she consented, she might recover the rest—whatever “the rest” meant.

“What happens if I don’t consent?” she asked.

Leni’s eyes were steady. “Then this is the last time you wake up.”

The words should have terrified her. Instead, they landed with a strange familiarity, like someone else had said them once, long ago.

Maris looked at the mirror again. She saw her own mouth parting, her own eyes darkening with a decision she hadn’t made yet.

“I consent,” she said.

The system chimed.

CONSENT RECORDED. RESTORATION COMMENCING.

A soft vibration ran through the bed. Through her bones.

Maris closed her eyes and waited for her memories to return.

Instead, she heard a whisper—so faint she could have imagined it—threading through the hum of the chamber.

Don’t trust the beach.

Her eyes snapped open.

“Did you hear that?” she asked.

Leni was already backing toward the door, face carefully blank.

“Hear what?”

Maris’s throat tightened. The copper taste returned, sharp and metallic, as if her body remembered how to die even when her mind didn’t.

“I heard someone,” Maris said.

Leni’s hand hovered over the door control. “No,” she said softly. “You didn’t.”

And then she was gone.
