Zero Day: The Static Protocol

The register beeped wrong.

Not the usual double-chirp when a barcode scanned clean. This was a single flat tone, low and dragging, like the sound itself was being pulled through mud. Kai Osei looked up from the conveyor belt, already halfway through an apology — *sorry, ma'am, let me try that again* — and saw the customer's face freeze mid-blink.

Not still. Not the way a person pauses. *Frozen*, the way a video stutters on a bad connection, one frame stuck and shuddering in place.

Then the skin along her cheek split into a grid of gray squares and fell apart like wet paper.

Kai didn't scream. He'd learned a long time ago, back when his father was still alive and the house still smelled like weekend pancakes, that screaming never bought you time. It only used up the time you had. So he stumbled back into the cigarette rack instead, knocking a carton of Marlboros onto the floor, and watched the world come apart around him one impossible piece at a time.

The ceiling tiles flickered between existing and not existing, strobing so fast his eyes ached trying to track it. The automatic doors up front slid open on a parking lot that wasn't there anymore — just a flat gray nothing stretching out to a horizon that hummed, low and constant, like a fridge left running in an empty house. The chip rack beside him lost its color first, then its shape, then dissolved into a soft rain of gray static that drifted to the floor and simply stopped existing before it landed.

*Static,* his brain supplied, uselessly, the way it did when he was scared and needed something, anything, to hold onto. *It looks like television static. Old TV, no signal.*

He didn't know where that thought came from. He'd never even owned a television that got static — those belonged to his grandmother's era, black and white sets with rabbit-ear antennas. But it was the only word his mind reached for, so it was the word he kept.

A rectangle of pale blue light unfolded in front of his eyes, thin as paper, hovering close enough that he could have touched it if his hands weren't shaking too hard to try. It hummed too, a different pitch than the horizon, higher and cleaner, almost electronic. Text scrolled across it in a font that looked machine-precise, each letter too perfectly formed to have been typed by a person.

**[SYSTEM RECLAMATION PROTOCOL — INITIALIZING]**

**[HOST STATUS: UNCORRUPTED]**

**[HOST DESIGNATION: ADMIN — PROVISIONAL]**

**[WARNING: REGION INTEGRITY AT 41% AND FALLING]**

**[ESTIMATED TIME TO FULL DECAY: UNKNOWN — INSUFFICIENT DATA]**

"Admin of *what*," Kai said out loud, and his voice cracked hard on the last word, betraying him.

The panel didn't answer. It just kept humming, patient in a way that felt almost cruel, like it already knew he'd figure out the wrong questions to ask before he found the right ones.

Behind him, he heard footsteps. Slow. Deliberate. Not the panicked scramble he expected from anyone else who'd just watched a woman's face turn to falling confetti.

"Kai?"

He turned. It was Renata — Renata who'd covered his last two closing shifts without complaint, Renata who kept a photo of her five-year-old taped inside her locker door, a crayon dinosaur the kid had drawn stuck to the break room fridge with a magnet shaped like a taco. Renata, except half her face was still gray and pixelated, the static crawling slow across her cheek like frost spreading on a window, and when she smiled at him her mouth had too many teeth in it now, rows of them, packed in tight and wrong.

"Kai," she said again, and this time three voices came out of her throat at once, layered on top of each other, none of them quite in sync. "Do you want to patch me?"

He didn't know what that meant. Not really. But something in his chest — something underneath the fear, older than it, more stubborn — recognized the shape of the offer the way you recognize a word in a language you haven't spoken since childhood. He knew, without knowing how he knew, that *patch* meant *fix*, and *fix* meant *save*, and Renata with her crayon dinosaur and her extra shifts and her kid waiting for her at daycare was still somewhere inside that static, if there was still time to reach her.

His hand found the box cutter on the belt before his mind caught up to his fingers.

"Stay back," he said, though he didn't move to run.

The blue panel flickered, and new text scrolled fast beneath the old.

**[HOSTILE ENTITY APPROACHING — CLASSIFICATION: CORRUPTED HOST]**

**[CORRUPTION LEVEL: 38% AND CLIMBING]**

**[RECOMMEND IMMEDIATE ACTION]**

"Immediate action," Kai repeated under his breath. "That's helpful. Thanks."

Renata took another step. Her sneakers — the same beat-up white ones she wore every shift, the left one held together with a strip of silver duct tape — scraped against tile that wasn't fully tile anymore, more like tile remembering what it used to be. The static under her feet rippled outward with each step, small gray ripples like she was wading through shallow water instead of walking on solid ground.

"It doesn't hurt," she said, and her voice cracked into a fourth register, higher, almost a child's. "Being static doesn't hurt at all, Kai. It's *quiet*. You should try it."

"No thanks," he said, and his grip tightened on the box cutter.

He thought about the door. He thought about running for it, out past the frozen parking lot and into whatever gray nothing waited beyond, and some part of him — the part that had spent six years since his father's funeral learning exactly how far a person could run before their legs gave out and reality caught up with them anyway — already knew that running wouldn't work. Not from this. Not from something that ate ceilings and parking lots and turned a woman's kindness into too many teeth.

So when Renata lunged, he didn't run.

He swung.

The box cutter caught her across the forearm, and it didn't draw blood — of course it didn't, there probably wasn't real blood left in her anymore, not in any way that mattered — it drew *pixels*, a spray of gray squares scattering off her skin like sparks kicked up from a grinder, tumbling through the air and winking out before they hit the floor. Renata shrieked, three voices climbing over each other in a sound that had no business coming out of a human throat, and staggered back half a step, clutching at the wound.

The blue panel surged brighter, crowding his vision edge to edge.

**[HOSTILE ENTITY DETECTED: CORRUPTED HOST — RENATA M.]**

**[OPTION A: NEUTRALIZE — REWARD: 15 XP]**

**[OPTION B: PATCH — REWARD: 40 XP, SURVIVOR RECOVERED]**

**[WARNING: PATCHING REQUIRES PROXIMITY. RISK OF CROSS-CONTAMINATION: HIGH]**

**[SELECT OPTION TO PROCEED]**

Kai stared at the words *survivor recovered* until they blurred.

He didn't know what XP was. He didn't know what cross-contamination meant, not really, not in any way he could picture happening to his own body. But he knew Renata's kid's name was Mia, because Renata talked about her constantly, complained good-naturedly about juice-box negotiations and bedtime stalling tactics, and Kai had listened to those stories on slow Tuesday closes because they were the closest thing to warmth this job had ever offered him.

He was not going to be the reason Mia's mother never came home.

"Patch," he said, loud enough that his own voice startled him. "Do the patch. Do it now."

The panel pulsed once, like something exhaling, and a thread of pale blue light shot out from his open palm — he hadn't even realized he'd extended his hand — and speared straight into the center of Renata's chest. She screamed again, but this time it was one voice, just one, human and raw and terrified in a way that was almost a relief to hear. The gray static crawled backward off her skin like a tide pulling out to sea, retreating from her collarbone, her jaw, the last patch of it draining from her cheek and leaving behind skin that was just skin, pale and sweat-slicked and *hers*.

Kai's own right arm went numb to the elbow. He looked down and watched, with a kind of distant horror he didn't have room to fully feel yet, as tiny flecks of gray static crept up under his sleeve, blooming across his skin like frost on a window from the inside out.

**[CROSS-CONTAMINATION: 6% AND RISING]**

The panel didn't tell him what happened at one hundred percent. He had a feeling — cold, certain, sitting low in his stomach — that he didn't want to find out.

Renata dropped to her knees on the broken tile, whole again, gasping his name over and over between sobs that sounded like relief and terror braided together. Kai crouched beside her, his numb hand hovering uselessly, not sure if touching her again was safe, not sure of anything except that it had worked, that she was *back*, that whatever this system wanted from him, it could apparently give as much as it took.

Then he heard the front doors.

Not sliding open on empty static this time. Footsteps — real ones, boots on broken glass, three sets, unhurried, patient in a way that made his skin crawl worse than Renata's had. Kai lifted his head and saw three shapes walking in out of the gray, silhouetted against the humming nothing where the parking lot used to be.

They weren't corrupted. He could tell that much even from here — no static crawling across their skin, no wrongness in the way they moved. They walked like people who had done this before, who had walked into a dozen static-choked stores just like this one and always walked back out again.

And every one of them was carrying a weapon.

They were looking directly at him.
