The northern sector burned on the fifth day.
The Hellions had become routine—their pilots knew the choreography by now. Sweep low, ignite the nests, roll out. The infested hardly fought back anymore. Most were too degraded to move, their nervous systems more hive-network than independent thought. They writhed and pulsed in the fire, and the marines stood guard to ensure nothing escaped the perimeter.
Jake moved through the ruins of the Meinhoff Central Hospital. He needed only a moment here—Raynor wanted confirmation that nothing remained alive, nothing remained infected. The structure was ancient, predating the colony by generations. Its corridors were now tombs.
Through the haze of thermal imaging, he extended his senses into the building. There were infested here. Dozens of them, maybe more. But they weren't moving. Some were too weak to rise. Others were conscious enough to know what was coming. Jake felt their awareness like static in his mind—fragmented, drowning, the last echoes of human consciousness trapped in bodies no longer their own.
An old woman. Once, anyway. She was in what had been the surgical ward. She could still think, somewhere in there. She was terrified.
Jake keyed his comm. "Building is clear for firebombing," he reported.
Raynor's voice came back steady. "Do it."
The Hellions came in a minute later. Jake was already clear. He watched the hospital burn from the ridge line, its silhouette etched against the orange glow. The fire would last for hours. Deep down, in the places that used to be flesh, those still-aware remnants would feel it. He didn't look away from that knowledge. There was no point.
Dr. Ariel Hanson was waiting in the hangar bay when Jake's dropship touched down. She had that look—anger, exhaustion, and something underneath it all that looked like determination. She motioned him toward the medical bay, away from the other soldiers.
They stood in her lab, surrounded by the tools of her research. Culture dishes. Genetic sequencers. Tissue samples in suspension fluid. Maps of the virus's mutation pathways.
"I've found something," Hanson said without preamble. "In the tissue samples. The infection doesn't have to be irreversible. In the early stages—first seventy-two hours—we might be able to interrupt the neural takeover. The zerg doesn't have the resources yet to completely override the host's synaptic structure."
She was angry—not at him, Jake realized. At the virus. At the situation. At the fact that she hadn't found this solution before.
"What you sensed in the hospital," she said. "The ones that were still thinking. Could they have been saved?"
Jake didn't hesitate. There was no point in lying to her. "Some of them. The ones who'd just turned. Maybe the ones from yesterday." He paused. "Most of them were too far gone. Five days in this environment, and the zerg structures have too much control. The personality, the self—it's not suppressed, it's buried under layers of compulsion."
Hanson's jaw tightened. "The next outbreak," she said, her voice low. "If there is one. We'll be ready. We'll have the cure before it spreads. They won't have to burn this way again."
She looked at him with something like gratitude, though Jake couldn't quite feel the weight of it. It was there, visible in her expression, but his emotional response was muted. He nodded anyway. It was the right response.
"Come up to the bridge," Raynor said over the comm.
Meinhoff hung in the viewport like a scarred stone. The radiation signatures were fading now. The virus was dead, burned out of the biosphere. The camps had been sterilized. The Agria refugees would be loaded onto transports within the hour, bound for Haven, a colony world in the Koprulu Sector that had offered to take them in. Meinhoff itself would be barren for years. Nothing would grow there. Nothing should grow there.
Raynor was standing at the viewport when Jake arrived, one hand resting against the glass. The commander looked older than he had when they'd arrived five days ago. The weight of the decision to burn that hospital was written across his shoulders.
"Mission's a success," Raynor said quietly. "Virus is contained. Colony's cleared."
Jake nodded.
Raynor turned to face him, and for a moment, there was silence. The commander's blue eyes were sharp, assessing. Taking inventory.
"You still in there?" Raynor asked.
It wasn't a casual question. Jake understood that. This was the one thing Raynor wouldn't hear a lie about.
"I'm changing," Jake said. "The zerg biology—it's optimizing me. I'm faster. Stronger. The detachment I use in combat, the emotional suppression—it's not just a coping mechanism anymore. It's becoming the default state."
"That's a problem."
"It might be. I'm aware of the trade-off. I can think about it. I can recognize that I should care more than I do. But the caring—it's becoming harder." Jake paused. "I'm still functional. Still effective. I can still take orders, make strategic decisions."
Raynor didn't look satisfied, but he nodded. He wouldn't push—that wasn't his way. The concern was visible on his face, though. Visible and real.
In his quarters, Jake tried to feel something about Meinhoff.
Grief. That's what he should feel. The weight of responsibility, the burden of what they'd had to do. The old woman in the hospital, one among dozens. The children who'd turned and burned. The ones who'd been conscious at the end.
He tried to access the emotional response, to dredge it up from somewhere in his mind. There was a recognition of the pattern—yes, this should be sadness. Yes, this should be guilt. Yes, this should be horror at what he'd participated in.
But the feeling itself was distant. Like hearing music through a wall. Present, but muffled. Separated from him by layers of neural restructuring and zerg-enhanced optimization.
The Zerg was making him better at killing. Better at efficiency. Better at compartmentalization. Worse at everything else.
Jake sat on the edge of his bunk and felt nothing about that, either.
And then—
There was a pulse in his chest. Not his heart. Deeper. Structural. A flicker of something that wasn't the heavy, efficient numbness of zerg optimization.
Something pulsed once beneath the Zerg architecture and the human baseline—faint, almost familiar, gone before he could locate it. The Protoss trace. Still there. Still threading itself through him, quiet and patient, like something that knew it had time.
The Hyperion's FTL drive engaged with a sound like distant thunder.
Jake stood in the observation lounge, watching Meinhoff shrink to a point in the viewport, then vanish as the stars blurred and stretched. The Agria refugees were in the hold below, secured in transport pods. Hanson was in her lab, already deep in her work, documenting her findings, building the framework for a cure. Raynor was on the bridge, plotting the course to Haven. Tychus was probably in his quarters, grinning about whatever credits the next mission would bring.
The ship accelerated. The stars became streaks of white light.
For the first time in five days, Jake allowed himself to feel one thing clearly: exhaustion. Not the emotional kind. Physical. The kind that came from five days of combat, of burning nests, of sensing the dying thoughts of creatures that had once been human. It was a small thing, tiredness. A simple thing.
But it was real.
