PATIENT ZERO -The lone survivor

The memory always began the same way. It started with the rhythm. Clack-clack. Clack-clack. The rhythmic lullaby of steel wheels rolling over the rails, cutting through the pitch-black darkness of the Southern Highlands.

It was midnight. We were on our way to Mbeya.

I was only eight years old then, small and curled up against the cold window glass, watching my reflection ghost over the passing trees. The cabin was quiet, filled with the soft breathing of sleeping passengers and the low murmur of adults talking in the corridor. It was peaceful. It was the kind of silence that usually precedes the end of the world.

Then, the air changed.

It wasn't a sound at first—it was a pressure. My ears popped, a sharp, painful sensation as if the atmosphere inside the train had been sucked out in a violent vacuum. Then came the light. It wasn't the yellow beam of the train’s headlight; it was a blinding, searing violet-white flash that turned the night into a terrifying noon.

Then came the bang.

It didn't sound like a crash. It sounded like the earth itself was cracking open. The world tilted violently sideways. The screech of tearing metal drowned out my own thoughts. I felt weightless for a horrifying second as our carriage lifted off the tracks, flipping through the air like a discarded toy.

When we landed, the silence was gone.

The darkness returned, but now it was thick with dust and the acrid smell of burning ozone. Then, the screaming started. It began as a low moan and rose into a cacophony of terror. I heard them all—from the youngest infants wailing for mothers who would never answer, to the guttural, desperate prayers of the elderly. I tried to move, but I was pinned. I tried to call out, but my throat was filled with ash.

I saw people reaching out in the twisted wreckage, hands grasping for salvation that wasn't there. No one came to save us. No heroes. No sirens. Just the fire, the screams, and that strange, pulsing violet light fading into the dark.

I was the only one who opened my eyes when the sun rose.

"Hey! Earth to you, man."

I blinked, the memory shattering like glass. The sterile fluorescent lights of the classroom flooded my vision. The smell of burning ozone was replaced by the scent of chalk dust and floor polish.

Ten years. It had been ten years since the Mbeya Incident.

I was in Form Six now. I was supposed to be focusing on my upcoming National Exams, supposed to be worrying about university applications and combinations. But my mind was always there. Back in the wreckage.

I looked down at my phone, hidden under the desk. On the screen was a grainy, digitized scan of an old newspaper article I had downloaded from the library archives.

MBEYA TRAIN DISASTER: MECHANICAL FAILURE OR SABOTAGE?

Official reports cite brake failure on the steep incline, but local witnesses report a flash of light moments before derailment...

"What was it?" I whispered to myself, scrolling past the official government statement. "A nuclear test? A weapon?"

It didn't make sense. If it was nuclear, why wasn't the land irradiated? Why didn't I have cancer? Why was I the only one who walked away without a scratch, while everyone else was buried in mass graves?

"Hey, what’s up?"

I jumped, quickly sliding the phone into my pocket. My friend, Juma, was standing over my desk, his backpack slung over one shoulder. He was looking at me with a frown creasing his forehead.

"I'm good," I lied, forcing a smile. "Just tired. What’s up?"

Juma didn't buy it. He leaned in closer, his voice dropping. "There is something wrong with you, bro. You’ve been zoning out all day. The teacher called your name three times during the Physics lecture and you didn't even flinch."

"I was just thinking," I said, packing my books with trembling hands. "About the exams."

"Mmh," Juma grunted, skeptical. "You look different today. Your eyes... they look heavy. Like you haven't slept in a week."

"Listen to me, I'm fine, man," I snapped, harsher than I intended. The stress was leaking out. "Just let it go."

Juma held up his hands in surrender. "Okay, okay. Never mind. Just take it easy, alright? See you tomorrow."

"Yeah. See you."

The school bell rang, a shrill sound that echoed too much like a scream in my sensitive ears. I grabbed my bag and headed for the door, desperate for fresh air.

The walk home was usually my way to decompress. The streets were alive with the chaotic energy of the city. Daladalas honked aggressively, weaving through traffic with reckless abandon. Bodaboda drivers shouted from street corners, revving their engines. The air was thick with red dust and diesel fumes.

Normally, I was careful. I was the kid who survived a train wreck; I knew how fragile life was. I checked both ways. I waited for lights.

But today, my mind was consumed by the newspaper article. A flash of light.

I stepped off the curb.

I didn't hear the horn until it was too late.

The sound was deafening—a blast of compressed air that vibrated in my chest. I turned my head, and time seemed to slow down into a frame-by-frame nightmare.

It was a semi-trailer. A massive, metallic beast of a truck, carrying a shipping container. The grille looked like the teeth of a monster. The driver was standing on his brakes, smoke billowing from the tires, but physics was a cruel master. A machine that heavy doesn't stop for a sack of meat and bone like me.

WHAM.

The impact didn't feel like pain. It felt like being hit by a collapsing building.

I was thrown from the tarmac like a ragdoll. The world spun in a dizzying blur of blue sky and grey road. I flew through the air, clearing the drainage ditch, and slammed violently into the trunk of a massive Mwarobaini tree on the side of the road.

The crunch was sickening.

I hit the ground and rolled, coming to a stop in the dirt. For a moment, there was no pain, only a cold, numbing shock. I stared up at the leaves of the tree, swaying gently in the wind.

Am I dead? I thought. Is this it? Finally?

Then, the pain arrived.

It hit me like a tidal wave of lava, washing over my entire nervous system. I opened my mouth to scream, but only a gurgle of blood came out. I tried to push myself up, to tell the crowd gathering around me that I was okay.

I looked down.

My scream finally found its voice. "AAAAAGH!"

My right leg was gone. Severed just below the knee, it lay a few meters away, a twisted lump of shoe and denim. But that wasn't the worst of it. My left arm had been crushed against the tree, detached completely at the elbow, hanging by a thread of skin before dropping into the dust.

Blood was pooling around me, turning the red dirt into mud. It was too much blood. No one survives this.

I saw a woman in the crowd cover her eyes. I saw a man vomit. Someone was shouting for an ambulance, but their voice sounded underwater.

"Help me..." I wheezed, my vision turning black at the edges.

And then, the itching started.

It began deep inside the marrow of my severed bones. It wasn't the cold of death; it was heat. Unbearable, white-hot heat.

CRACK.

The sound came from my leg. It sounded like a dry branch snapping, but louder.

I watched, horrified, as the bleeding stopped instantly. The blood seemed to boil and recede. Then, from the stump of my knee, something erupted.

It looked like raw meat moving on its own. Muscle fibers shot out like angry red snakes, weaving together in a frenzy of motion. They twisted and tightened, forming the shape of a calf.

"What... what is happening to me?" I shrieked.

SNAP. CRUNCH.

White bone shot out from the center of the muscle, lengthening, hardening, and locking into place. The sound of my own skeleton rebuilding itself was nauseating. It was agony—worse than the accident itself. It felt like invisible hands were stitching me back together with needles of fire.

My arm was next. I watched the radius and ulna bones shoot out from my elbow. Nerves reconnected with blue sparks of bio-electricity. Veins spider-webbed across the new flesh, pumping fresh blood. Finally, skin grew over the raw muscle, smooth and unblemished.

It took less than thirty seconds.

Where there had been a mangled corpse, I now lay whole. My clothes were shredded, soaked in blood that was no longer leaving my body. My shoe was still on the severed leg a few meters away, but my new foot was bare, pink, and perfect.

The crowd had gone silent.

I looked up. The horror on their faces had changed to something else. Fear. Pure, primal fear.

"He's a jini!" someone shouted. "Did you see that?"

"A demon!" another woman screamed, backing away.

Smartphones were out. Flashes were going off. I saw the unblinking lens of a camera pointed right at my face. They were recording everything.

I scrambled to my feet. My new legs felt powerful, springy, charged with an energy I had never felt before. The exhaustion from the morning was gone.

"Wait!" I yelled, reaching out with my newly grown hand.

The crowd recoiled as if I were radioactive.

Panic seized my chest. I couldn't be here. I couldn't let them see me. I didn't know what I was, but I knew I wasn't human anymore.

I turned and ran.

I didn't just run; I flew. I sprinted faster than any athlete, my bare foot pounding the pavement, the wind tearing past my ears. I left the accident scene behind, I left the truck driver staring at his bumper, and I left my old life in the dust.

But as I ran, the question burned in my mind, hotter than the fire that had just rebuilt my bones.

What is happening to me?

I know you want to know.

I do too.
