Chapter 2

Day Zero started with a traffic accident.

Marcus watched it on Feed 7, the camera covering the dirt road approach. A Ford pickup—Derek's neighbor, Calhoun—swerved at 6:12 AM, hit a ditch, and didn't get out. The driver's side door hung open. The interior was dark.

At 6:23, Calhoun emerged.

His gait was wrong. The coordination was missing, the purposeful stride replaced by a lurch that suggested neurological damage. His head tracked movements with the delayed response of a predator processing unfamiliar prey.

He walked toward the farmhouse.

Marcus checked his other feeds. State news: "Rabies outbreak reported in three counties. Residents advised to avoid contact with aggressive individuals." Social media: videos of attacks, being removed almost as fast as posted. Military chatter on shortwave: coded, urgent, escalating.

Same as Iteration 47. Same as 46. Same as every loop since he'd started paying attention.

The virus was always rabies at first. Always localized. Always containable—until it wasn't.

By noon, the official narrative would collapse. By dusk, the National Guard would deploy. By midnight, the power grid would flicker and die.

Marcus had twelve hours of infrastructure remaining. He spent them watching Derek.

The family woke at 7:30, unaware. Derek made coffee. Elena complained about the well water. Kyle demanded cereal that they'd forgotten to buy.

At 8:15, Calhoun reached the farmhouse porch.

Marcus could have warned them. He had the speaker system. He had Derek's phone number. In Iterations 1-15, he had warned people—neighbors, friends, strangers. Sometimes they listened. Sometimes they didn't. Always, they died.

Warnings didn't change outcomes. Data did.

Calhoun pounded on the door. Derek opened it—chain on, cautious but not cautious enough—and stared at his neighbor's blood-stained shirt.

"Cal? You okay, man?"

Calhoun lunged. The chain caught him, snapped his teeth six inches from Derek's face. Derek stumbled backward, slammed the door, locked it.

Elena's scream was high and thin. Kyle's was higher.

Marcus noted the timestamps. Subject D. Exposure Event 1: 08:17. Response time: 2.3 seconds. Correct defensive action. Previous iterations: inconsistent.

Derek was learning. Or he was lucky. Either way, the data was useful.

By noon, the family was barricaded. Calhoun had wandered off—attracted by distant gunfire, Marcus assumed—but Derek had seen enough. He'd watched the news. He'd tried to call the sheriff, gotten no answer. He'd tried to leave, found the road blocked by abandoned vehicles.

At 12:47, Derek made his first mistake. He called Marcus.

Marcus let it ring. Four times. Five. Six.

On the seventh ring, he answered.

"Marcus! Thank Christ. Listen, something's happening here. Something bad. Calhoun—he attacked me. He's sick. The news says rabies but—"

"I know," Marcus said.

Silence. Then: "You know?"

"I know what it is. I know what's coming. And I know you're sitting in a farmhouse with six hours of food, a well that doesn't work, and no weapons."

"How do you—"

"Because I sold you that farm, Derek. Because I chose it. Because every window is ground-level, every door is single-point, and the nearest neighbor is the man who just tried to eat your face."

Marcus could hear Derek's breathing accelerate. Panic, or anger, or calculation. In previous iterations, this was when Derek demanded entry to the bunker. When he threatened. When he begged.

This time, Derek said: "What do you want?"

Marcus smiled. Subject D. Behavioral variation detected. Iteration 48 anomaly?

"I want you to survive," Marcus said. "For now. I'll send coordinates tomorrow. Come alone. No Elena. No Kyle. Just you."

"Why?"

"Because I need to see if you've changed, brother. Or if you're still the man who opens doors."

Marcus hung up. Checked his water reserves. Checked his ammunition inventory. Checked the perimeter sensors.

Then he opened a new file on his laptop. Labeled it: THE GAMBIT. Began typing Derek's probable responses, branching scenarios, probability matrices.

At 6:00 PM, the power died. Right on schedule.

Marcus switched to solar. The monitors flickered, stabilized. The farmhouse feeds continued, now running on the generator Derek had found in the barn—a generator Marcus had left there, filled with exactly four hours of fuel.

At 8:30, the generator died. The farmhouse went dark.

Marcus sat in his bunker, surrounded by light and warmth and the humming of independent systems, and watched his brother stumble through the darkness with a flashlight and a kitchen knife.

At 9:15, Derek found the smoke detector camera.

He didn't destroy it. He stared into it. Directly into it. As if he could see Marcus through the lens, through the darkness, through the iterations.

"I know you're watching," Derek said. His voice was steady. Too steady. "Tomorrow. I'll come alone. But not because you ordered it. Because I have a better offer."

He reached up, gripped the camera, and didn't pull it down. He adjusted it. Pointed it toward the living room, where Elena and Kyle huddled on the couch.

"Watch them," Derek said. "While you can."

He walked away. The feed showed only the empty living room, the frightened family, the dark windows.

Marcus didn't blink. He reached for his keyboard and typed:

SUBJECT D: AWARENESS ACHIEVED. ADJUSTING PARAMETERS. THREAT LEVEL: ELEVATED.

Then he opened the hidden compartment beneath his desk, removed the pistol he kept there, and checked the magazine.

Fifteen rounds. Enough for Derek. Enough for Elena. Enough for Kyle.

Enough, if necessary, for himself.

The experiment was proceeding. But the variables were fighting back.
