The transition from the dark, cold drainage tunnels of District 13 back to the surface was a slow, agonizing crawl through a literal hell of rusted iron and toxic sludge. Every step Jack Mercer took was a negotiation with his own failing nervous system. His left side was a cage of fire, his bruised ribs screaming with every ragged breath he drew. His left wrist, swollen and purple from the sprain, was cradled against his chest like a dead bird. But the worst of it was the heat. A localized, boiling fever was cooking his brain, a direct side effect of the Splicing Ritual he had performed in the mud of that forgotten alleyway.

On the back of his neck, the fresh, jagged scar where the heavy brass needle of the pneumatic injector had pierced his flesh burned like a brand. When he ran his dirty fingers over it, he could feel the heat radiating from the wound, and in the reflection of the oily puddles beneath his feet, he saw it pulsing with a faint, unstable blue light. Malone’s neural fluid was settling into his brain stem, rewriting his biology, and his body was fighting the foreign tissue with everything it had.

He dragged his boots up the creaking wooden stairs of the tenement building on the corner of 4th and Blackwood. The rain outside was relentless, a heavy, acidic downpour that hissed against the rotting window frames of the stairwell. By the time Jack reached the third floor, his vision was swimming with red and blue static, the distant wails of police sirens still echoing in his ears.

He stopped outside the door with the frosted glass pane. The faded, gold-leaf lettering read *Mercer Investigations*, though the 'M' and the 'I' had peeled away years ago. He reached into his pocket with his right hand—his left was completely useless—and pulled out his keys. His chronic hand tremor was flaring wildly, the metal keys clinking against the brass lock like a frantic telegraph. It took him three attempts to guide the key into the slot, his knuckles scraping against the rough wood as his grip slipped.

He unlocked the door, slipped inside, and locked it behind him with a heavy double-turn of the deadbolt.

He was home. Or at least, in the grimy, cluttered space he called home.

The Mercer Investigations Office was a tomb of dust and old paper. The only light came from the flickering red and blue neon sign of the bar across the street, casting long, bloody shadows across the room. Old physical police files lay stacked on the floor, their edges yellowed by dampness. In the corner stood his case board, a chaotic web of red string, crime scene photographs, and handwritten notes all centered around one name: Sarah Mercer.

Jack didn't look at the board. He couldn't bear to. Instead, he stumbled toward his old leather desk chair and collapsed into it, letting his head fall back against the cracked upholstery. He closed his eyes, hoping for a moment of silence.

Instead, the voice returned.

*"You look pathetic, cop,"* Brick Malone’s voice rumbled inside his skull. It wasn't a memory, and it wasn't a distant echo. It was a physical weight, a coarse, heavy presence that felt like it was sitting right behind Jack’s eyes. *"Look at you. Shivering like a wet dog in a dirty kennel. You think you can carry my skin? You think you're strong enough to keep me locked up in here?"*

"Shut up," Jack muttered aloud, his voice cracking in the empty room. He pressed his palms against his temples, trying to squeeze the sound out of his head.

*"Come on, detective,"* Malone sneered, his psychic laughter vibrating through Jack's teeth. *"Let me out. I can feel those broken ribs of yours. I can feel that limp wrist. If you let me take the wheel, I'll harden us up. We'll go back out there. We'll find some of those pretty boys from the Gilded Sector and we'll break their teeth. I want to hear 'em crack. Don't you?"*

"I said, shut up!" Jack roared, slamming his right fist down onto the desk.

The impact sent his pencil cup clattering to the floor, but it did nothing to silence the enforcer. The voice only grew louder, more aggressive, clawing at the edges of Jack's consciousness like a trapped animal trying to dig its way through a plaster wall. The fever spiked, a wave of intense heat washing over Jack's face, and he felt a warm trickle of blood begin to run from his left nostril.

He was losing his grip. He had to partition the mind, just as Dr. Henry Cole had instructed.

Jack closed his eyes and forced himself to breathe. He visualized the *Mental Partition Method*. In the dark theater of his subconscious, he built a room. It was a classic police interrogation room, cold, sterile, and windowless. In the center sat a single metal chair under a harsh, swinging bulb. He visualized Brick Malone—massive, brutal, caked in concrete dust—strapped to that chair. He built four thick concrete walls around him, block by block, and then he installed a heavy, reinforced steel door. He slammed the door shut and slid a massive iron bolt into place.

The voice instantly muffled, reduced to a distant, frustrated thumping against the mental steel.

Jack gasped, opening his eyes. He wiped the blood from his lip with the sleeve of his trench coat. His heart was hammering, his skin drenched in a cold, greasy sweat. The partition was holding, but it was exhausting. It felt like holding a fire door shut against a raging backdraft; the moment his focus slipped, the door would burst open.

And he couldn't afford to let Malone out. Not now.

He had to learn to use the power he had stolen. If Malone's enforcers—the Concrete Crushers—found him, his father's old service revolver wouldn't be enough. He had exactly three rounds left in the cylinder, and the gang had dozens of men. He needed Malone's *Concrete Hardening*. He needed to understand how to call upon the stone without letting the monster take control of his body.

Jack stood up, his legs shaking from the fever. He walked over to his desk, where a heavy, ceramic coffee mug sat near the edge. It was a simple blue mug, one of the few personal items he had kept after Sarah's death.

He tensed his muscles, trying to channel the density from Malone's memories. He remembered the feeling of Malone's skin—the calcifying of the pores, the rapid dehydration of the epidermis, the mineral-like stiffness that turned flesh into armor. He let his anger rise, focusing on the men who had killed his wife, using his rage as a catalyst to spark the power.

That was his first mistake.

Anger wasn't his power; it was Malone's. The moment the rage flared, the mental partition cracked. The steel door in his mind groaned, and Malone's sadistic persona surged forward, seizing the connection.

Before Jack could react, his left hand—the sprained, swollen one—began to twitch violently. The swelling subsided, but not because it was healing. The skin turned a dull, matte grey. Pores fused together, calcifying into rough, jagged plates of dark slate. The grey stone raced up his fingers, covering his knuckles and his palm in a dense, heavy aggregate.

*"Yeah! That's it!"* Malone's voice screamed in his ear, his presence suddenly dominant. *"Crush it! Break something!"*

Jack's left hand moved without his consent. It lunged forward, his stone-hardened fingers wrapping around the blue ceramic mug. He didn't want to squeeze, but the muscle memory of the enforcer was absolute.

*CRACK.*

The mug shattered instantly. Shards of blue ceramic and fine clay dust exploded from his grip, embedding themselves in the rough stone of his palm. But Malone wasn't done. The stone-covered hand slammed down onto the old oak desk with bone-shattering force.

*CRASH.*

The heavy wood splintered, a deep crack ripping through the center of the desk. The vibration rattled up Jack's arm, sending a wave of agony through his sprained wrist that finally broke the psychic connection.

Jack screamed, pulling his hand back. He collapsed against the wall, clutching his left arm. The concrete texture was rapidly receding, the grey stone dissolving back into pale, bruised flesh. The ceramic shards that had been embedded in the stone fell to the floor, leaving deep, bleeding lacerations across his palm. His hand was a bloody, throbbing mess, his sprained wrist screaming in protest.

He slumped to the floor, his chest heaving as he stared at the ruined desk. A fresh wave of blood poured from his nose, dripping onto his leather coat. The mental exhaustion was crushing; his brain felt like it had been scrubbed with steel wool.

"Anger... is his," Jack wheezed, his eyes rolling back. "I can't... I can't use anger. It feeds him."

He realized the tactical error. Malone's power was built on violence and rage, but if Jack tried to use those same emotions, he would only open the door for the parasite to overwrite his mind. He had to find a different path. He needed a clean, disciplined focus. He needed a moral anchor.

With a hand that shook so violently he could barely control it, Jack reached into his inner coat pocket. His fingers closed around the cold, tarnished silver of *Sarah's Silver Locket*.

He dragged it out, his bloody thumb smudging the silver casing. He popped the latch.

Inside, the faded, water-damaged photograph of Sarah stared back at him. Her smile was quiet, gentle, and completely untouched by the violence of District 13. Staring at her face, the chaotic static in Jack's mind began to clear. The heat of the fever seemed to recede, replaced by a cold, sharp clarity.

This was *The Locket Focus*.

He stared at her picture for exactly sixty seconds, his breathing slowing, his heart rate dropping to a steady, controlled rhythm. He didn't think about his anger. He didn't think about the men who had killed her. He only thought about her. He remembered the sound of her voice, the warmth of her hand, and the promise he had made to find the truth.

He was a detective. His weapon wasn't rage; it was logic. It was discipline.

With his mind perfectly centered, Jack visualized the mental interrogation room once more. He saw Malone's persona, quieted by the sudden shift in emotional frequency. Jack calmly closed the steel door, slid the bolt, and locked it.

He stood up, his body still aching, but his mind absolute.

He looked at his right hand—his uninjured hand. He tensed his muscles, not with anger, but with cold, deliberate focus. He recalled the physical memory of the concrete, but this time, he filtered it through his own analytical mind. He structured the calcification, directing the density to form only over his knuckles, keeping the joint movement free.

It worked.

Slowly, smoothly, the skin over his right knuckles turned a dark, polished grey. The transformation was quiet, precise, and completely under his control. The rough, stone-like texture formed a perfect, dense brass-knuckle-like shell over his hand. He knocked his right fist against his left palm; it sounded like two solid blocks of granite colliding. There was no pain, no twitching, and no voice screaming in his ear.

He had done it. He had controlled the stone.

But as Jack turned to look in the cracked mirror hanging on the office wall, his heart froze.

In the reflection, his right hand was hardened into grey concrete, but his eyes... the whites of his eyes had vanished, replaced by a brilliant, unstable, glowing blue light. It was the *Blue Sclera Flash*.

Jack stared at his own glowing eyes in horror. The blue light was intense, casting a pale, cold shadow across his face. It was the undeniable signature of the Subject Zero serum, a physical side effect of activating any copied superpower. To the privatized police force and the advanced scanners of Aegis Corp, those eyes were a beacon. If he used this power on the streets, he would light up their surveillance grid like a flare in the dark.

He let the concrete power recede, his skin returning to normal, and the blue light in his eyes slowly faded back into bloodshot white. He leaned against the sink, his breath trembling.

Every time he fought to survive, he would be inviting them to find him.

Before he could process the terrifying implication, a frantic, heavy rattling shook the office door. The lock clicked, and the door burst open.

Jack spun around, his right hand instantly shifting back into the rough grey stone, his eyes flashing with that dangerous, unstable blue light.

Standing in the doorway, drenched in rain and panting heavily, was Leo. The fourteen-year-old street kid was clutching his modified radio to his chest, his oversized jacket dripping puddles onto the rotting floorboards. His face was pale, his eyes wide with absolute terror.

"Jack!" Leo gasped, his voice cracking as he slammed the door behind him and threw the deadbolt. "Jack, you gotta get out of here! Malone's enforcers... the Concrete Crushers... they found the alley. They know Malone is dead, and they're tearing District 13 apart looking for his missing body. They're checking every PI office, every clinic on the block. They're coming here, Jack!"
