Chapter 8: The Knife’s Edge
The damp earth smell of the tunnel was a living thing, thick and cold, coating Harmony’s tongue. It mixed with the sharper tang of rust from the abandoned tracks snaking away into absolute darkness. Only a single, distant emergency exit sign cast a sickly red glow, painting the hulking shape of a derelict subway car in bloody shadows. The silence wasn’t empty; it hummed with the phantom vibration of long-dead trains and the drip, drip, drip of water finding its way through cracked concrete far above. This was Gotham’s forgotten vein, and Harmony moved through it like a ghost, her sneakers silent on the grit-covered ties.
She’d doubled back. Against every screaming instinct that told her to vanish into the Narrows and never look toward Arkham again, she’d circled like a moth drawn to a dangerous flame. The news reports screamed about the breakout, the carnage. The Joker’s gang had scattered, Harley’s name conspicuously absent from the list of recaptured inmates. Harmony knew. She knew where Harley would go when things went sideways, when the laughter turned sour. A place Joker rarely bothered with, deep under the city’s skin.
A choked sob echoed off the curved tunnel walls. Not loud, but raw. Human. Cutting through the industrial drone. Harmony froze, heart hammering against her ribs like a trapped bird. It came from the broken subway car. The door hung half off its hinges, a dark maw. She approached slowly, every sense screaming danger, every step amplifying the memory of cold steel against her temple, Joker’s rancid breath. But beneath that terror was something else, a gnawing pull she couldn’t name or ignore.
Inside the car was deeper dark, smelling of mildew and old metal. Shapes loomed – gutted seats, dangling wires. Harmony’s eyes strained. Then she saw her. Huddled deep in the corner, curled into a tight ball almost lost in the gloom. Blonde hair, streaked with grime and something darker, matted. The vibrant colors seemed leached out in the gloom. Harley Quinn wasn’t laughing. Great, wracking shudders wrenched through her small frame, the sounds escaping her throat raw and wet, stripped of all its usual manic energy. It was the sound of something breaking.
Harmony crept closer, the crunch of glass underfoot impossibly loud. Harley flinched violently but didn’t look up, pressing her face harder into her knees. That’s when Harmony saw it. The glint of light on polished metal. Nestled high on Harley’s left thigh, buried almost to the ornate, monogrammed hilt – a long, wicked-looking knife. J. Fingerprints undoubtedly obliterated, but the gaudy, personalized handle screamed its ownership. Blood, shockingly dark against the pale skin of Harley’s leg and the grey fabric of ripped fishnets, soaked the area around it, pooling on the filthy floor.
"Harley?" Harmony’s voice was a dry whisper, swallowed by the tunnel’s vastness.
No response, just another choked sob. Harmony knelt, the cold dampness of the concrete floor seeping through her jeans. Up close, the damage was worse. Harley’s knuckles were raw and bloody, a bruise purpling along her jawline. Her breath hitched in shallow gasps between sobs. Harmony reached out, hesitant, her fingers trembling. Not to touch the knife, not yet. Just to brush a strand of filthy hair from Harley’s damp cheek.
Harley flinched again, her head snapping up. Her eyes, wide and bloodshot, locked onto Harmony’s. For a second, there was no recognition, just animal panic, a cornered thing. Then, slowly, focus returned. The blue, usually sparkling with mischief or malice, was dull, clouded with pain and something deeper – a shattered kind of humiliation.
"You," Harley rasped, her voice shredded. A flicker of the old defiance tried to surface but drowned in a wave of agony as she shifted slightly. She looked down at the knife, then back at Harmony, her expression unreadable in the gloom. "Shoulda kept runnin’, rabbit." The words were scraped raw, devoid of the teasing lilt Harmony remembered. They held only bleak exhaustion and a terrible kind of regret. Her eyes rolled back, her body went limp, collapsing sideways like a puppet with cut strings. She landed heavily against Harmony’s kneeling legs, unconscious.
The sudden weight, the warmth of blood soaking into Harmony’s jeans, the complete stillness where there had been frantic energy moments before – it jolted Harmony into action. Panic flared, cold and sharp. The Joker’s knife. Harley’s blood. The echoing silence of the tunnel suddenly felt like a trap closing in.
Think. First aid. Stop the bleeding. Her mind raced, shaky but forcing itself into clinical mode, a remnant of a past life observing symptoms. She couldn’t leave the knife in. Pulling it could cause more damage, make the bleeding worse… but leaving it in guaranteed infection, risked it shifting. Harmony took a deep, shuddering breath, steeling herself against the coppery smell, the unnatural angle of the blade. Her fingers, surprisingly steady now, closed around the cold, intricate hilt – the ‘J’ pressing into her palm like a brand.
She braced Harley’s leg with her other hand, feeling the unnatural heat radiating from the wound. "Okay, Harls," she murmured, more to herself than the unconscious woman. "This is gonna suck." She pulled.
The resistance was sickening, a wet, tearing sensation transmitted through the handle. Harley didn’t wake, but a low groan escaped her lips, her body tensing instinctively against the pain even in unconsciousness. The blade came free with a slick, sucking sound. Harmony dropped it instantly, the metal clattering on the concrete, the monogram now slick with its owner’s blood.
Blood pulsed from the wound in rhythmic spurts. Harmony ripped a strip from the bottom of her own t-shirt, wadding it into a pad. She pressed down hard, directly on the puncture site, using the heel of her hand for maximum pressure. Harley whimpered, a small, broken sound that twisted Harmony’s gut. The fabric soaked through alarmingly fast. Harmony added her other hand, leaning her weight into it. Hold pressure. Just hold pressure.
Harley’s breathing was shallow and rapid. Her skin felt clammy. Shock. Harmony scanned the dark interior of the car. Nothing. No clean water, no bandages beyond what she was sacrificing from her own clothes. The distant red exit sign mocked her. Getting Harley out, up to street level, past Joker’s scattered goons or GCPD patrols… it was impossible. She was trapped underground with a bleeding, unconscious Harley Quinn, and the owner of that knife could be hunting them right now.
The pressure pad was saturated. Harmony peeled back a corner. The bleeding hadn’t stopped. It oozed steadily. Too steadily. She needed to elevate the leg. Carefully, trying not to jostle the wound, she maneuvered Harley onto her back, propping her injured leg up on a lump of debris wrapped in another torn piece of her shirt. It was a pathetic splint, but the best she could do. She reapplied pressure, this time using the last large strip of fabric she could spare from her t-shirt, now just a ragged crop top.
Harley’s head lolled to the side. In the dim red light, her face looked unnervingly young and pale beneath the grime and fading bruises. Vulnerable. The chaotic energy that usually crackled around her was utterly absent, leaving only this broken shell. Harmony remembered the fierce protectiveness in Harley’s eyes back in Arkham, the iron grip on her wrist, the whispered run. She remembered the terrifying, exhilarating kiss against the padded wall, the confusing mix of fear and fascination that had coiled inside her ever since.
She pressed down harder on the wound. Harley needed a doctor. Real medical attention. But taking her to a hospital was a death sentence – either from the law or from the Joker finding out. Harmony looked at the pale face, the blood soaking through her makeshift bandage, the discarded knife gleaming dully nearby. The rabbit hadn’t kept running. She’d circled back. And now, in this dripping, forgotten artery beneath the city, with the scent of blood and rust thick in the air and the echo of Joker’s malice hanging unseen, Harmony Hayes realized the game had irrevocably changed. She wasn’t running from anymore. She was hunkering down. Protecting. The weight of Harley’s head resting against her thigh was a terrifying anchor, binding her to the storm. She pressed down on the wound and waited, listening for footsteps in the dark.
The pressure under Harmony’s palms grew slick and insistent, Harley's blood soaking through the last strip of her t-shirt. The tunnel’s silence pressed in, heavy with the drip of water and the thud of her own frantic heartbeat. She strained, listening for the scrape of a boot, the manic giggle that meant death was stalking the dark. Harley’s breathing hitched, a weak, wet sound that sent a fresh wave of panic through Harmony.
"Stay with me, Harls," she whispered, voice cracking. "Come on, you lunatic. Don't you dare check out on me now." The cold concrete bit into her knees, the metallic tang of blood thick in her nostrils, mixing with the tunnel’s damp decay. She adjusted her grip, applying more weight, desperate to stem the sluggish ooze.
A soft rustle, like dry leaves skittering over stone, came from the shadows near the broken train car’s entrance. Not footsteps. Something… else. Harmony froze, head snapping up, eyes wide, searching the gloom beyond the meager red glow. Every nerve screamed danger. Her free hand scrabbled on the grimy floor, fingers closing around a jagged chunk of broken brick.
"Show yourself!" Her voice echoed, thin but defiant. "I got nothin' to lose, and I will bash your skull in!"
Silence. Then, movement. A figure detached itself from the deeper shadows near the peeling, rust-speckled wall. Not a goon. Tall, poised, moving with an unnerving, fluid grace that seemed detached from the tunnel’s grime. Ruby hair, impossibly vibrant even in the gloom, cascaded like a waterfall over shoulders draped in deep green fabric that seemed woven from living leaves. Her skin held an almost phosphorescent pallor. She stepped into the faint red light filtering from the distant exit sign, her eyes, sharp and intelligent, fixed first on the unconscious Harley, then on Harmony’s blood-stained hands clutching the brick.
"Bashing skulls seems rather… counterproductive," the woman observed, her voice a low, resonant murmur that somehow cut through the dripping silence. Her gaze, cool and assessing, swept over Harley’s limp form, the makeshift bandage, the discarded, gore-smeared knife bearing its damning monogram nearby. A flicker of something complex – concern? Annoyance? – passed over her striking features. "Especially when she’s leaking quite so impressively." She took another step, the scent of crushed ivy and damp earth suddenly overpowering the blood and rust.
Harmony tightened her grip on the brick, shifting her body slightly to shield Harley. "Who are you? Friend of his?" She jerked her chin towards the knife.
The red-haired woman – Poison Ivy, Harmony realized with a jolt, recognizing the description from whispered Arkham legends – gave a short, humorless laugh, like dry twigs snapping. "Hardly. The Clown Prince of Pestilence and I have… divergent views on ecosystem management." She knelt smoothly, effortlessly, beside Harley, ignoring Harmony’s defensive posture. Her fingers, unnervingly deft, brushed aside the sodden bandage Harmony had torn from her shirt. "Pressure’s good," Ivy murmured, her clinical tone at odds with her appearance. "Pointless, but good. Deep puncture. She’s lost too much." Her cool fingers pressed lightly near the wound, making Harley moan softly.
Harmony watched, the brick heavy and useless in her hand. Ivy’s presence was overwhelming, radiating a quiet, terrifying power. "Can you… help her?" The question felt small, desperate.
Ivy didn’t look up. She traced the edges of the wound with a fingertip. Tiny, almost invisible tendrils seemed to stir beneath Harley’s pale skin where Ivy touched. "Perhaps. She’s stubborn. Annoyingly resilient." A sigh escaped her, carrying the faint scent of ozone and loam. "Always stumbling into trouble. Dragging others down with her." Her eyes finally lifted, pinning Harmony with an unnervingly direct gaze. "Like you, little rabbit. You should have kept running."
The echo of Harley’s own raw words sent a shiver down Harmony’s spine. "Couldn’t," she said simply, meeting Ivy’s gaze, the brick lowering slightly. "Not without her."
Ivy studied her for a long moment, a calculating look in her green eyes. Then, a hint of dry amusement touched her lips. "Sentiment. How… human." She turned back to Harley, her hand hovering over the wound. "This will sting, Harleen. Try not to scream and attract every rat in Gotham." Ivy’s fingertips pressed down, not on the wound, but on the inflamed skin around it. A faint, verdant light, barely perceptible, seemed to emanate from her touch, sinking into Harley’s flesh.
Harley jerked, a gasp tearing from her throat. Her eyes flew open, wide with confusion and pain. The haze cleared slightly, focusing first on Ivy’s face inches from her own. "Red?" Harley rasped, her voice a wrecked whisper. A weak, lopsided smirk tried to form. "Didn't... order... room service..."
"Quiet," Ivy commanded, her concentration intense. The faint green luminescence intensified subtly around her fingers. The oozing blood seemed to slow, the angry flush around the puncture receding fractionally. "You’re making a mess of my tunnels."
Harmony watched, awestruck and wary, as Ivy worked her strange, botanical magic. The immediate, pulsing threat of Harley bleeding out ebbed, replaced by the potent, unsettling energy of Poison Ivy’s presence. Harley’s eyes fluttered, struggling to stay open, drifting past Ivy to find Harmony. A flicker of surprise, then something softer, warmer, touched her exhausted features before her eyelids sank shut again, her breathing deepening into something resembling sleep rather than unconsciousness.
"She’s stabilized. For now." Ivy withdrew her hand, the subtle light fading. She wiped her fingertips fastidiously on a large, waxy leaf that seemed to unfurl from her sleeve. "The knife was… personal. He won't be pleased she’s still drawing breath. Or that someone pulled it out." Her gaze rested on Harmony again, speculative. "He’s close. Like mold on damp stone. Smelling the blood."
The scent of old blood hung heavy in the tunnel’s stagnant air, a coppery lure Ivy insisted would draw him like a carrion crow. Harmony’s gaze snapped towards the jagged hole in the train car, heart hammering against her ribs. Every distant drip sounded like a footstep. Every rustle was a goon.
"Close," Ivy confirmed, her voice a low thrum that vibrated in Harmony’s bones. She slid surprisingly strong arms under Harley’s limp shoulders and knees, lifting her with unsettling ease. Harley moaned, a thin thread of sound. "Move, rabbit. Or become fertilizer." Ivy didn't wait, turning towards the deeper gloom beyond the derelict train, Harley’s head lolling against her shoulder.
Harmony scrambled after them, leaving the monogrammed knife glinting dully on the filthy floor. Ivy moved with preternatural grace through the oppressive dark, navigating crumbling debris and slick patches as if the tunnel were her living room. Harmony stumbled, her sneakers sliding on wet concrete, breath catching. The thought of that purple suit materializing behind them was ice in her veins.
They plunged deeper, the air growing thicker, damper, smelling less of decay and more of rich, wet earth and something green and sharp. The distant red exit sign vanished, swallowed by absolute blackness that pressed in like velvet. Harmony reached out, fingers brushing slimy tunnel wall, panic fluttering. "Ivy?"
"Quiet." Ivy’s voice was a command. Ahead, an impossible patch of deeper darkness resolved into a narrow fissure in the curved concrete wall, almost hidden behind a cascade of thick, rubbery vines Harmony hadn’t noticed. Ivy ducked, sliding through with Harley, vanishing.
Harmony squeezed in, the rough concrete scraping her arms. The passage sloped sharply down, twisting. The tunnel’s chill vanished, replaced by a sudden, startling warmth. The air changed completely; damp earth, yes, but layered with vibrant scents – loam, ozone, crushed herbs, the heady perfume of unseen flowers. It was humid, alive.
They emerged. Harmony gasped. She stood not in a tunnel, but a vast, hidden grotto bathed in an eerie, shifting light that seemed to emanate from the very walls and ceiling. Glistening roots snaked across surfaces, pulsing faintly with verdant energy. Impossible ferns unfurled fronds wider than her arm span. Strange, luminous mushrooms clustered like tiny lamps on shelves carved into the rock. In the center, fed by a trickle of clear water, stood a large, natural stone basin filled with dark water. This wasn't a hideout. It was a subterranean jungle heart.
Ivy crossed to a wide, moss-covered ledge near the water, laying Harley down with surprising gentleness. The moss seemed to sigh beneath her weight. Harmony rushed to Harley’s side, falling to her knees, her hands instinctively hovering over the blood-soaked bandage. Harley’s skin was still too pale, her breathing shallow. The reality of the wound, the sheer amount of blood Harmony’s ruined shirt had soaked up, crashed over her. "She needs a doctor," Harmony whispered, her voice raw.
Ivy was already moving, plucking leaves and stems from nearby plants with swift precision. "She needs me," Ivy stated, her back turned, her tone leaving no room for argument. She crushed a cluster of deep purple berries in her palm, mixing the paste with water scooped from the basin. The mixture fizzed faintly. "Doctors ask questions. Questions get answered. Answers get people killed." She turned, holding the dark paste. "Hold her leg. Firmly."
Harmony pressed her hands down on Harley’s thigh, just above the wound, feeling the weak pulse beneath her fingers. Ivy peeled back the makeshift bandage. The puncture was an angry, dark hole, oozing sluggishly. Harmony swallowed bile. Ivy smeared the paste directly into the wound. Harley jerked awake with a strangled cry, eyes flying open, wild and unfocused.
"Easy, idiot," Ivy murmured, holding her down with surprising strength. Her other hand pressed flat against Harley’s stomach, a sudden intensity in her posture. That subtle verdant glow bloomed again beneath her palm, flowing outwards, sinking into Harley’s skin like water into parched earth. Harley gasped, her back arching off the moss, then slumped, the tension draining away. Her eyes fluttered, finding Harmony’s face inches from her own. A weak, dazed smile touched her cracked lips.
"Heya, Doc," Harley rasped, her voice a threadbare whisper. Her hand, trembling, lifted slightly, fingers brushing Harmony's bloody knuckles where she held her leg. "Told ya... shoulda run..." Her eyes drifted shut again, but her breathing deepened, steadier than before. The angry flush around the wound visibly receded, the oozing slowing to a mere seep.
Harmony stared, numb. She looked from the impossible, glowing plants to Ivy, whose expression was tight, focused, radiating controlled power. Here, deep beneath Gotham in a place that defied logic, with a woman who commanded plants and another who laughed while bleeding out, Harmony felt utterly unmoored. The sterile intake room at Arkham felt like a lifetime ago. The scent of disinfectant was replaced by loam and blood and Harley's faint, familiar sweat beneath the grime. Ivy meticulously cleaned the wound with water and a pungent-smelling leaf, then applied a thick poultice of mashed, glowing green moss, securing it with broad, flexible leaves she bound with sinewy vines. "He won’t find this place," Ivy stated, finally sitting back, wiping her hands on more leaves. "The roots hide us. They smell only stone and water."
Harmony slumped back against the cool, living wall, the adrenaline crash hitting her like a physical blow. Her hands, sticky with Harley’s blood, trembled uncontrollably. She looked at Harley, unconscious again but breathing easier, then at Ivy, a being of terrifying power who’d just saved them. "Why?" Harmony asked, the word scraping out. "Why help her?
Ivy studied her for a long moment, her green eyes unreadable. She glanced at Harley, a flicker of something complex – exasperation? Affection? – crossing her face. "She’s chaos," Ivy said finally, her voice low. "But she’s my chaos. And sometimes... chaos needs shelter from the storm." She stood, brushing moss from her dress. "Rest. The storm is still raging up there." She gestured vaguely upwards. "He’ll tear the city apart looking." Ivy moved towards another section of the grotto, her form merging with the vibrant shadows. "Try not to bleed on the moss."
