The maintenance hatch groaned, a low, metallic shriek that echoed through the hollow ribcage of the South Building. Kaelen followed the girl into the throat of the facility, his boots crunching on broken glass and spent shell casings. The air here was different—thicker, tasting of stagnant coolant and the cloying, sweet rot of the "Infected."
Kaelen's legs felt like lead. The adrenaline that had kept him upright during their encounter in the Atrium was draining away, leaving behind a cold, hollow exhaustion. He watched the back of the girl's head, her black-red hair swaying with every silent step she took. She moved like a shadow—weightless, purposeful.
"Wait," Kaelen rasped, leaning his hand against the damp concrete wall to steady himself. "How do you know? About the others. How do you know they're coming for us right now?"
The girl stopped. She didn't turn around, but her shoulders squared.
"The air," she whispered. Her voice didn't carry; it seemed to vibrate directly into his mind. "It vibrates. Every living thing has a pulse, Kaelen. A hum. The ones who have turned... their hum is a scream. It's jagged. Broken. I can feel the friction of their hunger rubbing against the walls of the corridors three levels up. They smelled the harvest of Miller. Now, they smell the 'quiet' of you."
She finally turned, her pupils still wide, swallowing the faint amber light of his shoulder-mounted lamp. "My senses are maxed out. To me, this building isn't dark. It is a map of heat and noise. And right now, the map is turning red."
Kaelen tried to nod, but the motion sent a fresh spike of white heat through his neck. He took a step forward, but his right knee buckled. The world did a slow, sickening roll. He reached out to catch himself, but his hand found only empty air.
Before he could hit the floor, she was there.
It wasn't a blur; it was as if she had simply ceased to be in one spot and existed in another. She caught him by the waist, her grip like iron bands. Without a word, she grabbed his heavy, trembling arm and draped it over her small shoulders.
"Hold on," she commanded.
Kaelen stiffened, his heart hammering against his ribs. "Wait—what are you doing? I can... I can walk."
"You are leaking," she said flatly, referring to the blood still matted in his hair. "If you fall, you stay down. If you stay down, they eat. I am your crutch now."
She began to walk, taking half of his weight with an ease that shouldn't have been possible. Kaelen felt the terrifying heat radiating from her skin—the bio-thermal energy of a high-tier Cannibal constantly regenerating its own cells.
"I don't get it," Kaelen muttered, his head lolling near her ear as they shuffled down the darkened service tunnel. "Why truly help me? The 'quiet' isn't a real reason. Not for your kind. You aren't exactly known for having... common sense. Or mercy."
The girl was silent for a long moment. "Perhaps," she said softly, "I am the first."
They turned a corner, the smell of the cafeteria—or what was left of it—drifting toward them. Kaelen's stomach let out a violent, prolonged growl.
"Sorry," Kaelen winced. "My stomach... it's been over five hours since I last ate. I'm a technician, not a bio-tank. I need fuel. Would you mind if we tried to make it to the cafeteria? There might be some sealed rations left."
She didn't answer. She simply adjusted her grip and veered toward the double doors marked RECREATION & DINING.
As they crossed the threshold, the girl went rigid. She shoved Kaelen backward, propping him against a vending machine with a force that knocked the wind out of him.
"Stay," she hissed.
From the shadows near the industrial refrigerators, two shapes detached themselves. They were far gone—"Frenzy" stage. Their skin was translucent and grayish, showing the black, pulsing veins beneath. Their eyes weren't just dilated; they were bleeding, the dark red hue now a weeping, angry crimson.
They didn't scream. They made a wet, clicking sound.
The girl stepped forward. Her black-red hair seemed to bristle. "Back," she warned, her voice dropping into a low, predatory growl.
The two Cannibals lunged.
The violence was surgical. The girl met the first one mid-air. She caught the creature's reaching arm and snapped the radius and ulna like dry kindling. Before it could recoil, she drove her palm into its chest. The force didn't just knock the creature back—it collapsed its ribcage inward with a wet, splintering crunch.
The second one tackled her. They hit the floor in a tangle of limbs. Kaelen watched as the girl's eyes went fully void-black. She reached up, her fingers digging into the Frenzy-attacker's eye sockets. There was a sickening pop, followed by a shriek that sounded like a boiling tea kettle. She twisted, her Uncapped Strength allowing her to literally tear the creature's jaw from its hinges.
She stood up, her chest heaving, the dark red stains under her eyes pulsing with a violent light. She looked at the bodies—at the cells she needed to pay her "Debt"—but she didn't eat. She turned her head back toward the darkness behind Kaelen.
"More," she whispered.
From the ventilation shafts and the shattered kitchen windows, more eyes began to open. Dozens of them. The "Loud Ones" had arrived. The scent of Kaelen's blood was no longer a trickle; to the monsters in the dark, it was a dinner bell.
Kaelen gripped his technician's wrench, his knuckles white. "There's too many."
The girl looked at him, a stray drop of black blood on her cheek. "Then we don't stay for the meal," she said, her voice regaining that fragile tone. "We run."
