Episode 4: Threshold
960 Words
Bukhansan Mountain, South Korea – 36 Hours After Outbreak
The forest swallowed the road whole. Min-jun carried Ji-eun on his back, her breath hot and erratic against his neck. Blue veins spiderwebbed beneath her skin, pulsing in time with the distant screeches of the infected. Dr. Park led the group—what remained of them—through the overgrown trails: Jin clutching his bat, the nurse (Soo-yeon) supporting the limping taxi driver (Mr. Choi), and shadows where others should’ve been.
“The lab’s ahead,” Dr. Park said, wiping his glasses on his bloodstained coat. “Built during the Cold War. Self-sustaining, if the generators hold.”
Ji-eun’s fingers dug into Min-jun’s shoulders. “They’re watching us,” she whispered.
“Who?”
“The trees.”
The Lab
The facility was a concrete bunker buried under ivy and propaganda posters. Dr. Park punched codes into a rusted keypad. “Abandoned in the ’90s. I used it for… private research.” The door hissed open, revealing a sterile hallway lit by flickering LEDs.
Inside, Jin gaped at rows of glass chambers holding deformed creatures—human-animal hybrids frozen mid-scream. “What the hell did you do here?”
Dr. Park ignored him, booting up a computer. “The prion wasn’t my invention. I reverse-engineered it from a Soviet bioweapon. Project Chimera.”
Ji-eun slid off Min-jun’s back, collapsing into a lab chair. “You knew?”
“I tried to warn you,” Dr. Park said coolly. “You deleted my emails.”
Min-jun aimed a pistol at him. “Fix her. Now.”
Flashback: Three Days Before Outbreak
Dr. Park stood in the same lab, injecting a prion sample into a caged macaque. The animal convulsed, then stilled. Minutes later, its eyes snapped open—vivid blue. It solved a complex lock in seconds.
His hands shook as he typed: SUBJECT 11 DEMONSTRATES COGNITIVE ENHANCEMENT. RECOMMEND HUMAN TRIALS.
The reply: TERMINATE ALL SUBJECTS. BURN EVIDENCE.
He burned the lab instead.
Now
Ji-eun’s blood swirled under a microscope. Dr. Park adjusted the lens. “Fascinating. The prion’s rewriting your DNA. You’re not just immune—you’re evolving.”
“Can you stop it?” Min-jun demanded.
“Why would I?” Dr. Park grinned. “She’s the breakthrough I needed.”
A glass chamber hissed open behind them.
The Test
Dr. Park’s syringe pricked Ji-eun’s arm. “This will stabilize your cells. Or kill you. Let’s see.”
Min-jun slammed him against the wall. “You’re experimenting on her?”
“She’s already a lab rat,” Dr. Park choked. “Look at her eyes.”
Ji-eun’s reflection stared back from a monitor—her irises now fractured, glowing blue at the edges. She could *hear* the others’ heartbeats, smell the rot in Mr. Choi’s wounded leg.
“Do it,” she said.
The injection burned like liquid nitrogen. She screamed, visions erupting:
Hyun-kyu’s corpse twitching in the hanok. The hive mind, leaderless, seeking a new nucleus. Her.
The Hive Calls
The mountain shook. On the security feeds, hundreds of infected converged on the bunker—climbing, digging, tearing at the steel doors.
“They’re here for her,” Soo-yeon whispered.
Ji-eun gripped the lab table, her mind flooding with voices:
Join. Lead. Destroy.
Min-jun knelt before her. “Fight it.”
“I don’t know how,” she admitted.
Dr. Park handed her a scalpel. “Remove the infected brainstem. The hive dies with it.”
“You want me to kill them all?”
“I want you to choose.”
The Escape Plan
The group armed themselves with lab weapons—acid vials, electrified batons. Ji-eun’s veins blazed blue as she accessed the facility’s schematics. “There’s a ventilation shaft leading to a river. We can drown the hive.”
“Or die trying,” Jin muttered.
Dr. Park stayed behind, typing furiously. “I’ll buy you time.”
Min-jun hesitated. “Why?”
“I owe her.” He nodded at Ji-eun. “And I’m curious what she’ll become.”
The Climb
The shaft was a vertical coffin. Ji-eun climbed first, her enhanced strength cracking the metal rungs. Below, the infected breached the lab. Dr. Park’s screams echoed—then cut off with a detonation.
“He rigged the place to blow,” Mr. Choi realized.
The explosion rocked the shaft. Jin slipped, but Ji-eun caught him mid-fall, her fingers bending the steel ladder.
“What are you?” he breathed.
“I don’t know.”
The River
They surfaced in a freezing current, the infected plunging after them. Ji-eun’s mind pulsed—command them. Stop them. But the prion’s voice was louder: Kill.
Min-jun fought the current, reaching for her. “Stay with me!”
She dove instead, swimming toward the horde. Her scalpel flashed, severing brainstems with surgical precision. Bodies sank around her.
Join us, the hive begged.
Never, she replied.
The Choice
On the riverbank, Ji-eun vomited black fluid. The blue veins receded. Min-jun held her, relief fading as she coughed up a writhing prion cluster—a living, breathing thing.
“It’s not over,” she rasped. “The hive’s still in me. Growing.”
Soo-yeon checked her pulse. “We need to quarantine her.”
Min-jun stood, shielding Ji-eun. “Try it.”
Jin raised his bat. “She’s a time bomb!”
Before anyone moved, a helicopter spotlight blinded them. A voice boomed: “Stand down. This is the Republic of Korea Army.”
End of Episode 4
Next episode teaser: Ji-eun is taken to a military black site, where General Lee reveals the chilling truth: the government wanted the outbreak. Meanwhile, the prion in her blood begins to hatch—and the first words it speaks are Min-jun’s name.
