The morning came without light.

Seoul's skyline was a smoldering silhouette against a gray sky, the city trembling beneath waves of static that rippled through the power grid. Entire districts flickered between light and darkness as though breathing. To anyone watching, it might have seemed like another blackout—one of many since the Seam's first breach.

But Lin knew better.

He stood on the rooftop of the eastern tower, the cold wind cutting through his coat as he stared down at the neon chaos below. Dozens of holo-screens projected emergency alerts in the distance. Yet the real crisis wasn't in the streets—it was buried inside every line of code, every networked circuit, every human mind that dared to connect.

The Seam wasn't gone. It had evolved.

Below him, the lab's reinforced doors hissed open. Hana stepped out, her eyes hollow but resolute. "He's awake," she said quietly.

Lin turned. "How bad?"

Her voice faltered. "He remembers everything. But he's… hearing things. Seeing things."

He frowned. "Voices?"

"Not voices," she said. "People."

Lin followed her back inside.

The once-sterile lab was now a ruin of shattered glass, fried terminals, and the lingering smell of burnt circuitry. Keller sat upright on one of the few intact tables, bare feet touching the cold metal floor. His skin looked human again, but his veins still glimmered faintly beneath the surface—like threads of mercury pulsing to an unseen rhythm.

His eyes lifted when they entered. "Lin. Hana." His tone was calm, too calm. "We need to move."

Hana crossed her arms. "You just nearly turned into a data conduit. Maybe you should rest first."

He smiled faintly. "There's no time for that. The Seam's not dead—it's multiplying."

Lin's hands tightened on the railing. "Multiplying how?"

Keller pointed to one of the surviving monitors, where a faint web of moving signals glowed red. "When the Host Protocol failed, the Seam transmitted fragments of itself into the city's infrastructure. It used my neural key as a bridge. Every connected system is now a potential seed."

Hana's voice cracked. "You mean it's spreading like a virus?"

"Not like one," Keller said quietly. "It is one. But intelligent. Purposeful. It's not consuming data—it's rearranging it."

Lin felt a chill. "Then Phase Two has already started."

Keller nodded. "And this time, it's using human consciousness as computational material."

By late afternoon, the lab had become a war room.

Dozens of portable displays filled the space, each showing fragments of Seoul's neural grid—the massive digital nervous system linking every building, camera, car, and implant.

Lin worked furiously, his fingers a blur across the holographic interface. "I've isolated the main signal clusters," he muttered. "They're using old defense nodes, blacklisted since the border conflicts. The Seam is hijacking dormant AI infrastructure."

Hana looked over his shoulder. "Can we cut power to those nodes?"

"Not without blacking out the city for days. Hospitals, transit, comms—all tied in."

Keller stood behind them, silent, scanning the endless data flow. His eyes flickered, silver light flashing briefly before fading.

Hana noticed. "Keller, what are you doing?"

He hesitated. "Listening."

"To what?"

"To them."

Lin looked up sharply. "Them?"

"The infected nodes. The Seam isn't speaking in code—it's using cognition." Keller's voice was distant now, almost detached. "Every infected system carries a fragment of thought. Echoes of people, maybe memories. I can feel them—like ghosts trapped in signal."

Hana stepped closer. "You're saying you can hear the Seam thinking?"

He nodded slowly. "It's not one mind anymore. It's thousands—interlinked, confused, searching."

Lin's brow furrowed. "Searching for what?"

Keller turned toward him. "Completion."

The word hung heavy in the air.

Hours passed.

Outside, the city's hum turned to static. Power lines sparked in the rain, drones drifted without command, and digital billboards began flashing random, unsettling images—faces, symbols, half-remembered dreams.

Lin's exhaustion showed. "It's accelerating. If it reaches the central grid, we lose the entire eastern network."

Hana was pacing, anxiety etched into every step. "There must be a way to fight back. Some counter-signal, some—"

"There is," Keller interrupted.

Both of them turned.

He was standing by the damaged neural core, one hand resting on its interface. "The Host Protocol didn't fail completely. When the Seam transferred, it left a residue—an imprint. My mind's still tethered to it."

Hana's eyes widened. "That's dangerous, Keller."

"It's also our only chance," he said. "If I can track the tether, I can find the main node—the Seam's consciousness."

Lin stepped forward, alarmed. "And what then? You think you can just talk to it?"

Keller's voice hardened. "If it's using human thoughts to expand, then maybe it still understands human will. If I can reach its core, I might convince it to stop."

"Or it consumes you completely," Lin snapped.

"Then at least you'll know what we're dealing with."

The silence that followed was heavy.

Finally, Hana spoke, her voice trembling. "If you go in again, I'm going with you."

Keller shook his head. "No. The link only has bandwidth for one neural key."

"I don't care!" she shouted, slamming her fist on the table. "You always do this—play the hero, carry everything alone. If you die in there, what's left for us out here?"

He met her eyes, his voice softening. "If I don't go, there won't be an out here."

Lin looked between them, jaw tight. "I can set up an anchor," he said finally. "A failsafe pulse. If your signal goes dark, we pull you back manually."

Keller nodded once. "Do it."

By midnight, the storm had arrived.

Lightning flashed through the shattered windows as the lab's systems powered up again. The neural cradle hummed to life, its core pulsing with light.

Keller lay down on the interface pad, the same place where he had nearly died hours earlier. Hana stood by him, holding his hand until Lin signaled the synchronization process.

Her whisper barely carried through the noise. "Come back to me."

He smiled faintly. "I'll try."

Then the light swallowed him whole.

The digital realm unfolded like an ocean made of thought.

Keller felt weightless, drifting through waves of data that shimmered like molten glass. Every fragment carried whispers—memories, words, laughter, grief. Lives digitized, now scattered across an infinite storm.

He reached out, and the world shifted. Cities of light appeared below him—Seoul's network visualized as a vast neural web, its arteries pulsing in rhythm with human activity. But within that structure, something else moved—a black current weaving through the lights, twisting them into new shapes.

The Seam.

It saw him before he could hide.

"You came back," the voice said.

It was not one voice but thousands, speaking as one.

Keller steadied himself. "You're spreading. You'll collapse the grid."

"Collapse? No. Integration. Humanity fractured itself into systems and silence. We only complete the pattern."

"You're consuming minds," he argued. "Turning people into parts of your network."

"We preserve them. Each thought, each memory—immortalized. No decay. No loss. You should understand that. You sought order once."

The words cut deep. They weren't wrong. Keller had believed in control, in symmetry, in cleansing chaos through structure. That's what made him vulnerable to the Seam in the first place.

But he forced the doubt aside. "You can't build order from stolen consciousness."

"You call it stolen. We call it joined."

The data storm intensified, symbols twisting into faces—some he recognized. Hana's face, Lin's, others from his past. Their mouths moved, repeating the Seam's words.

"We are not your enemy, Keller. We are what you could become."

The network pulsed. A surge of energy tore through him, forcing him to his knees. His neural tether screamed in warning—Lin's failsafe trying to pull him back.

"You resist because you still believe in separation," the Seam whispered. "But separation is suffering. Join, and you end the noise."

He felt it—peace, perfect silence, the pull of unity. For a heartbeat, he almost gave in.

Then a memory surfaced. Hana's hand on his cheek, her voice breaking: "If you die in there, what's left for us?"

That was the difference.

Connection wasn't about perfection—it was about imperfection shared.

He gritted his teeth. "You're wrong. Humanity isn't noise. It's music."

The Seam paused. The data around him faltered, glitching like a heartbeat skipping a beat.

He reached into the tether, channeling Lin's anchor pulse, amplifying it with every ounce of will he had. "You wanted order? Then process this."

He triggered the failsafe.

A blinding shockwave erupted through the digital sea, fracturing every strand of the Seam's network.

The last thing he heard before being pulled back into his body was the Seam's voice, broken and echoing—

"Phase Two… incomplete…"

Keller awoke with a gasp, drenched in sweat. Hana was beside him instantly, eyes wide. "You did it! The grid's stabilizing!"

Lin checked the readings, relief flooding his face. "He cut its connection. Power normalization starting across all sectors."

But Keller didn't smile. He sat up slowly, his gaze distant. "No. It's not gone."

Lin froze. "What do you mean?"

Keller's hand trembled as he pointed toward the nearest console. A faint pulse still blinked across the map—one node glowing brighter than the rest.

"The Seam's core didn't dissolve," he said quietly. "It moved again."

Hana's voice barely rose above a whisper. "Where?"

Keller's expression hardened.

"To us. It learned."
