They put Evan in Room 4 because it was the smallest.
Not because anyone said it out loud, but because it was easier to control a smaller space. Easier to seal. Easier to watch. Easier, they told themselves, to keep everyone else safe.
Evan sat on the edge of the hospital bed, his feet dangling just above the linoleum. He still wore his sneakers because no one had thought to ask him to take them off. He was seventeen. Thin. Pale in that washed-out way teenagers get when they haven't slept enough and live on energy drinks and vending-machine food. His oversized hoodie was zipped all the way up, the hood pulled low, like he was freezing despite the stifling, recycled heat of the crowded unit.
He kept rubbing his right side, just below the ribs. Over and over.
The bite wasn't large. That was the problem. It had happened somewhere in the chaos—on the stairs, in the crushing crowd near the ER doors when people had been pressed too close together and no one had been looking down. The skin around the wound was already darkening, a bruise blooming outward in ugly purple and gray tones. The teeth marks were shallow but unmistakable, crescented just below his ribs in a perfect, human-shaped arc of ruin.
Outside the heavy wooden door, a woman's voice was tearing itself raw.
"Let me in! Please, let me see him! That's my boy!"
It was the woman from the hallway, the one who had screamed when Evan's shirt had been pulled up. Two nurses were physically holding her back, her sneakers squeaking against the tile as she fought them with the frantic, adrenaline-fueled strength of a terrified mother. She wasn't a large woman, but panic gave her leverage, her hands clawing at the doorframe.
Sharon stood in the doorway of Room 4, looking back at the woman, and then at Evan, who was shivering on the mattress, his eyes darting like a cornered rabbit.
"Let her in," Sharon ordered, her voice cutting through the noise.
Officer Daniels stepped into Sharon's space, his hand resting instinctively on his heavy leather belt. "Doc, are you sure? If he turns while she's in there—"
"I said let her in," Sharon repeated, her tone leaving no room for debate. "But Daniels, you stand right behind her. If he seizes, if he bites, you pull her out immediately. Do you understand me? You do not hesitate."
Daniels gave a grim, single nod and motioned to the nurses. They released the woman. She practically fell through the doorway, stumbling into Room 4 with a ragged, tearing sob.
"Evan!" she cried, throwing herself toward the bed.
"Ma'am, stop!" Daniels barked, stepping forward and catching her firmly by the shoulders before she could crush her son in a hug. "You can't touch his right side. You cannot get near the wound. Keep your hands where I can see them."
The mother gasped, fighting the officer's grip for a second before the reality of the dark blood and the swelling bruising on her son's torso anchored her. The fight drained out of her legs. She sank to her knees beside the bed, reaching out with trembling, desperate hands to gently cup the unbitten side of his face. "Oh, Evan. My sweet boy. I'm here. Mom's here."
"Mom," Evan whimpered, leaning into her palm, tears tracking through the grime and sweat on his face. "I didn't tell you. I was scared. I didn't want them to leave me behind in the stairwell."
"I know, baby. I know." She kissed his forehead, her lips lingering against his burning skin. She looked up at Sharon, her eyes wide, desperate, and completely shattered. "You're a doctor. You have medicine. Please. Give him antibiotics. Cut it out. Do something!"
Sharon stepped forward, her movements slow and deliberate, keeping her hands visible and her voice as steady as she could manage. "We are going to do everything we can to keep him comfortable. But right now, we need to keep him under observation. We don't have a cure for this, ma'am. We don't even have a name for it."
The mother's eyes darted past Sharon to the heavy nylon medical restraints hanging over the bed rails. Her breath caught in her throat. "No. No, you aren't tying him up like an animal! He's just a boy! He's my son!"
"Mom, it burns," Evan whimpered, twisting on the mattress. His hand tightened around the metal bed rail until his knuckles turned bone-white. "Am I going to die?"
The silence that followed was an answer all its own. It hung in the sterile air of Room 4, heavier than the dying hum of the hospital's backup generators.
They had to move fast. Evan's breathing was speeding up, his chest rising and falling in shallow, panicked hitches. Someone handed Sharon the restraints—thick, soft medical straps meant to keep delirious or combative patients from pulling out their IV lines. Evan flinched violently when he saw the nylon webbing.
"No," he said, scrambling backward on the mattress until his spine hit the wall. "Mom, don't let them! You said you were helping me!"
"We are," Sharon said, though her voice shook now. She forced herself to look him in the eye. "This is for safety, Evan."
"For whose?" he demanded, his voice cracking into a shriek.
His mother openly sobbed, her forehead resting against the edge of the mattress. "Let them do it, Evan. Please. Just let them help. Please, baby, don't fight them."
Officer Daniels approached. He crouched so he was eye-level with the boy, his large frame blocking the doorway. "Evan. I need you to listen to me."
Evan's breath hitched. "You're going to shoot me."
Daniels swallowed hard, his hand resting far away from his holster. "No. I don't want to use my gun. I want you to be safe. But we have to make sure you don't hurt yourself if the fever gets too high."
The first strap went around his right wrist.
Evan screamed. Not a loud scream. Not yet. Just a sound ripped straight from the center of absolute panic—raw, childlike, and sudden. His body bucked as the nurses moved in to secure him, his heel kicking against the metal bed frame with a sharp clang that echoed too loudly in the quiet unit.
"Hold him—gently—" Angela ordered, her hands trembling as she grabbed his other arm, pinning it to the mattress.
"Evan, breathe—" Sharon urged, working the buckle.
The second strap went on. Then the third. By the time they finished securing his ankles, Evan was shaking so badly the entire bed rattled, the metal squeaking under the strain.
"I don't want to die," he sobbed, thrashing weakly against the thick nylon. "I don't want to turn into one of them. Mom, please! Tell them I won't hurt anyone! I promise!"
His mother stroked his sweaty hair, tears streaming down her own face, dripping onto the pristine white hospital sheets. "I'm right here, Evan. I'm not leaving you. I promise. I'm right here."
Evan's breathing changed first. It went from fast and shallow to uneven, hitching in strange, unnatural rhythms. He gasped as if the air in the room had suddenly turned to water. His fingers curled against the restraints, the tendons standing out starkly beneath his pale skin.
"My side hurts," he whimpered, twisting against the straps. "It feels like it's on fire."
Sharon moved closer, pulling a penlight from her pocket and checking his pupils. They were dilated. Too fast. Too wide. The infection was moving with terrifying, metabolic speed. It wasn't waiting for him to die; it was burning him alive from the inside out.
"Temp?" she asked, not looking away from his eyes.
"103.8," Angela said, staring at the digital thermometer like it was a live grenade.
Evan whimpered again, then cried out as his back arched sharply off the mattress. "Make it stop!" he screamed. "Please—please—"
The sound ripped through the unit, tearing through the fragile, glass-thin quiet they had managed to maintain in the hallway. Down the hall, someone knocked over a medical cart in surprise. A baby started crying, a thin, wailing siren. From the barricaded stairwell at the end of the wing, fists began to strike the metal almost immediately—drawn by the noise of Evan's pain like moths to a flame.
The heavy doors shuddered under the sudden, violent impact.
"Sharon," Daniels said urgently, looking over his shoulder. "We can't let him keep screaming. They're going to break the doors down."
Evan's eyes rolled back briefly, then snapped forward again—focused now, frantic, and filled with a terrifying awareness of what was happening to him. "Mom," he sobbed, looking at the woman clutching his hand. "I don't want to hurt you. Get away from me."
"I'm not leaving you!" she cried, kissing his knuckles over and over.
Sharon made the call. The only call she had left.
"Sedation," she said.
The word landed heavy in the small room.
Angela hesitated, a loaded syringe already in her hand. "Sharon, if we sedate him and he... changes while he's under—"
"I know," Sharon said sharply. Then, softer, her medical oath warring with her survival instinct: "I know, Angela. Just do it."
They prepped his IV with shaking hands. Evan watched them, sheer terror flooding his pale face. "What is that?"
"Something to help you rest," Sharon said, leaning in close so only he could hear her over the pounding outside. "It will help with the pain, Evan."
"Am I going to wake up?"
Her throat closed completely. "Yes," she lied. Because telling him the truth would have shattered whatever humanity he had left.
The needle went into the port.
Evan cried out again—a loud, panicked shriek—and the sound set off a chain reaction across the floor. The pounding at the stairwell door intensified into a frantic, deafening rhythm. From the opposite end of the wing, something heavy slammed into the locked double doors separating them from the rest of the hospital. Metal rattled. The building was coming alive with hunger.
Evan's voice cracked and rose, his words slurring as the chemicals hit his bloodstream. "Mom—"
"I'm here, baby," she whispered, her face buried in his shoulder. "I'm right here."
The sedation hit fast. His body slackened abruptly, his head lolling to the side. His breathing evened out into shallow, ragged pulls. His eyes fluttered, then closed.
Room 4 went deathly quiet.
But the moaning outside pressed closer, the building answering the noise with teeth.
Sharon stood there for a long time, staring down at the boy she could not save, only slow. This was the reality of the infection. It wasn't an explosion. It wasn't a sudden moment of cinematic horror where the dead simply rose. It was a waiting game. It was a slow, agonizing, biological theft of the soul.
They turned the lights down further. No one spoke above a whisper. Time stretched thin, pulled taut over the silence.
Evan began to convulse exactly an hour later.
It wasn't violent at first—just small, involuntary jerks that shook the mattress and made the restraints creak. His breath hitched. His jaw worked silently, like he was chewing something that wasn't there.
"Sharon," Angela whispered from the doorway.
Sharon was already moving. Evan's mother was dozing in a chair pulled close to the bed, her hand still resting over his restrained wrist. She woke with a start as the bed began to shake.
"Evan?" she murmured, rubbing her bloodshot eyes.
His temperature had climbed again, completely overriding the medication. Sweat soaked the sheets beneath him, turning the fabric translucent. When Sharon lifted his shirt, the bite had turned entirely black at the center. The tissue was necrotic, smelling of swamp gas and old pennies, with angry red veins spidering outward, pulsing faintly in time with his erratic heartbeat.
"Evan," Sharon said softly, checking his responsiveness.
His eyes snapped open.
They weren't right. The white sclera was heavily bloodshot, a cloudy, bruised purple bleeding in from the corners. He looked at Sharon, then shifted his gaze downward to the woman beside him. He didn't look at her like a son looking at his mother. He looked at her wrist, tracing the pulse point with his eyes.
Then, his mouth opened, and a sound came out that wasn't a word.
It was a low, wet, guttural snarl.
"Evan, honey?" his mother asked, leaning closer, her voice thick with sleep and denial. "Are you awake?"
Evan strained against the restraints with terrifying, sudden strength. The metal bed frame groaned loudly as his body fought the nylon straps. Foam gathered at the corners of his mouth. His jaw distended slightly, his teeth snapping together just inches from her arm, hard enough to crack his own enamel.
"Oh God," Patrice whispered, backing out into the hall.
"Evan!" his mother shrieked, jumping back, stumbling over the legs of her chair.
He lunged toward the sound of her fear, the purple in his eyes glowing in the dim light. The restraint across his chest caught him, the thick nylon digging into his skin, but he didn't stop snapping his teeth at the empty air where she had just been.
Officer Daniels moved instantly, lunging into the room and grabbing the mother around the waist, hauling her backward. "Get back! He's turning!"
Evan snarled again, a wet, animalistic roar that tore from his throat.
Sharon backed away, her heart breaking entirely. She turned to the med cart, her hands flying over the vials, reaching for the paralytic. She had to shut him down before the noise brought the barricades crashing in.
But as her fingers closed around the glass vial, the snarling abruptly hitched.
Evan's body went rigid, locking up completely, and then he choked. He coughed violently, his chest heaving as he gasped for air. The terrifying, inhuman growl broke, morphing into a ragged, deeply human sob.
Sharon turned back, freezing.
Evan sagged against the mattress, panting heavily. The cloudy purple in his eyes seemed to recede just a fraction, battling against the white, blinking back tears. He looked at Daniels. He looked at Sharon. Then, slowly, agonizingly, he looked at his mother trembling in the officer's grip.
"Mom?" he gasped, his voice trembling and entirely his own.
The mother let out a strangled cry, trying to push past Daniels. "I'm here!"
"No!" Evan shrieked, straining away from her this time, pressing his head back into the pillow as far as the straps would allow. "Mom, don't come near me! Don't touch me!"
"Evan, baby, it's okay—"
"It's not okay!" he sobbed, the sheer horror of his own mind reflecting in his tear-filled eyes. "I wanted... Mom, I looked at you and I wanted to bite you. I wanted to tear your arm open."
He squeezed his eyes shut, thrashing his head from side to side in pure agony. "Get out! Please get out! I can't stop it! I'm in here but I can't stop it!"
The room fell into a horrifying, suffocating silence, broken only by the teenager's weeping.
Sharon slowly lowered her hand from the med cart. This was infinitely worse than a sudden death. The infection didn't just flip a switch. It came in waves. It was a parasitic tide, pulling the host under, letting them up for a gasp of air just to realize they were drowning, and then pulling them back down again. He was trapped inside a body that was actively betraying him, fully aware that he was becoming a monster.
His mother collapsed against Daniels, wailing in a pitch that made the other survivors in the hall cover their ears.
"I'm sorry," Evan cried, his voice dropping into a ragged whisper as another violent shiver wracked his spine. "I'm so sorry."
He squeezed his eyes shut, and when they fluttered open a second later, the purple had crept further in. The tears stopped. His jaw locked. The low, wet growl started in the back of his throat again.
Sharon sagged against the wall, her knees threatening to give out.
Evan was only the first. And somewhere, somehow, in the chaos of the stairs or the crush of the ER, he had been bitten.
Which meant—
"How did he get bit without anyone seeing?" Patrice whispered from the hallway, voicing the terror they were all feeling.
Sharon closed her eyes as Evan's snarl grew louder, straining against the nylon.
Another voice followed from down the hall, shaking with fear. "And if it happened to him..."
The unspoken question filled the entire 4th floor, settling like ash over the survivors.
Who else?
And where had it happened?
The moaning outside answered with patient, terrifying certainty. The night was far from over, and the real threat was actively losing his mind, locked inside with them.
