The walk back to Sector 12 took forty minutes.
Forty minutes of keeping to shadows. Forty minutes of avoiding main roads where gangs patrolled and guards asked questions. Forty minutes of feeling his new body adjust, settle, become something he didn't recognize.
Kael moved differently now.
He didn't notice at first. Too focused on getting home, on the vial in his bag, on the blood drying stiff on his clothes. But somewhere around the third alley, he realized his footsteps made no sound.
Not quiet. Silent.
His boots touched broken glass and rusted metal and crumbling concrete, and nothing. Not a crunch. Not a scrape. Like his body instinctively knew how to distribute weight, where to step, how to move without disturbing the air.
That's not normal, some distant part of him thought.
He kept walking anyway.
You pass a group of scavengers huddled around a trash fire in Sector 9.
They don't look up.
One of them glances in your direction, squints, then looks away. Like you're not worth noticing. Like you're part of the shadows.
Before today, you would've been grateful for the invisibility.
Now it feels different.
Now it feels earned.
The slums of Sector 12 smelled like rot and rust and too many bodies crammed into too little space.
Home.
Kael slipped through the gap between two collapsed buildings, a shortcut only locals knew and emerged into the maze of shanties that made up the residential block. Corrugated metal walls. Tarps for roofs. Extension cords stolen from Zone 2 power lines, flickering with unstable electricity.
Their shack was at the end of the row. Smaller than most. Cleaner than most.
Seris insisted on that. Even dying, she insisted on dignity.
The door was a piece of plywood held in place by rope hinges. Kael paused outside, looking down at himself for the first time since leaving the courtyard.
Blood. Everywhere.
His jacket was shredded, barely hanging on. The tank top beneath was stiff with dried gore, his own and the beetle's. His cargo pants were torn at the knees, soaked dark. His hands were the worst. Caked in layers of red and black and green, fingernails still dark and sharp even though he'd willed them back to normal.
He couldn't let Seris see this.
There's a water barrel around the side of the shack.
Rainwater collection. Contaminated, technically, but not enough to matter for washing. You strip off the ruined jacket, ball it up, shove it behind the barrel. The tank top follows.
The water is cold. You don't care.
You scrub your hands first. The blood comes off in sheets, turning the water pink, then red, then black as you reach the deeper layers. Your skin beneath is smooth. Unbroken.
Too smooth.
You remember your shoulder being torn open. Remember seeing your own ribs. Remember the beetle's mandibles grinding through muscle and fat.
Now there's nothing. No scars. No marks. Just skin that looks... new. Pale and perfect in a way that doesn't match the rest of you.
You scrub harder.
It doesn't help.
Kael cleaned himself as best he could. Face. Arms. Chest. The wounds that should have killed him were gone, replaced by flesh that felt wrong under his fingers. Denser. Smoother. Warmer than it should be.
He pulled a spare shirt from the hidden cache behind the barrel always keep backup clothes, Seris taught him that and slipped it on. Dark fabric. Loose fit. Hid the changes in his body well enough.
His hands were the problem.
The nails had receded, but they were still too dark. Too sharp at the edges. If Seris looked closely, she'd notice.
He shoved them in his pockets and pushed open the door.
The shack was small. One room divided by a hanging sheet. A cooking area with a portable burner. A table made of stacked crates. Two sleeping mats on the floor.
And Seris.
She sat at the table, wrapped in a blanket that couldn't hide how thin she'd become. Twenty-three years old but looking older now. Gaunt. Fragile. The black veins of mutation visible on her neck, creeping toward her jaw like cracks in porcelain.
She looked up when he entered.
"You're late."
Her voice was steady. Controlled. The voice of someone who'd learned to hide fear behind routine.
"Got held up," Kael said.
"Held up how?"
"Jackals were in Sector 7. Had to take the long way back."
The lie came easy. Too easy. When had lying to his sister become natural?
Seris studied him. Her eyes still warm brown, still human moved over his face, his clothes, his hands shoved in his pockets.
"You changed your shirt."
"The other one got torn."
"How?"
"Climbing a fence."
"Kael."
"I'm fine."
You cross to the table. Pull the vial from your bag. Set it down in front of her.
Her eyes widen.
"You got it," she breathes.
"Told you I would."
"But the cost— how did you—"
"I had enough."
Another lie. You had exactly enough because you spent everything. Because you scavenged for two months straight. Because you took jobs that left your hands bleeding and your back broken.
Because you'd do anything for her.
She doesn't need to know that.
Seris picked up the vial with trembling fingers. The liquid inside was pale blue, almost luminescent. Stabilizer solution. The only thing keeping the mutation in her body from spreading faster.
Not a cure. Just a delay.
One week of delay. Then they'd need more.
Always more.
"Thank you," she whispered.
Kael sat down across from her. "You should take it now. You've been off the medication for three days."
"I will." She set the vial down gently. "But first, tell me what really happened."
"I told you. Jackals. Fence. Long way home."
"You're lying."
The words hit like a slap.
Seris's eyes were fixed on him. Not angry. Not accusatory. Just tired. Tired in the way only someone who'd been lied to by everyone she loved could be tired.
"I raised you, Kael. I know when you're lying. You've been doing it more lately. Every time you come home, there's something you're not telling me."
"Seris—"
"I'm dying." She said it simply. Factually. "We both know it. The stabilizers are slowing it down, but eventually they'll stop working. Eventually, the mutation will win."
"Don't talk like that."
"I'm not being dramatic. I'm being realistic." She reached across the table. Her fingers thinner than they used to be, veins too visible beneath pale skin touched his wrist. "I need you to be honest with me. If something's happening, if you're in danger, I need to know. I can't protect you if I don't know."
*You can't protect me at all,* Kael thought.
He didn't say it.
You look at your sister. At the woman who raised you after your parents died. Who fed you when there wasn't enough food. Who held you when you cried and taught you to survive when the world wanted you dead.
She's dying.
And you're changing into something that might not be human anymore.
How do you tell her that?
How do you explain that you killed a D-rank monster with your bare hands tonight? That you ate its core like a piece of fruit? That your body healed wounds that should have been fatal and now you can see in the dark and hear heartbeats and feel hunger for things that shouldn't be food?
You can't.
So you give her a truth wrapped in lies.
"There were Jackals," Kael said slowly. "They caught me on the way back. Wanted the medicine."
Seris's grip tightened on his wrist.
"I fought them off. Got roughed up a bit, but nothing serious. That's why I changed my shirt."
"You fought off Jackals? How many?"
"Four. Five. I don't know. It happened fast."
"Kael, they're a gang. Some of them are Carriers. You're—"
She stopped.
Kael waited.
"You're unawakened," she finished quietly. "You shouldn't have been able to fight them off."
"I got lucky."
"That's not luck. That's—" She stopped again. Her eyes narrowed. "Show me your hands."
Cold spread through Kael's chest. "What?"
"Your hands. You've been hiding them since you walked in. Show me."
"Seris—"
"Now."
You don't want to do this.
Every instinct screams at you to refuse. To make an excuse. To leave before she sees what you've become.
But this is Seris.
This is the only family you have left.
You can't lie to her forever.
Kael slowly pulled his hands from his pockets.
He placed them on the table, palms down.
Seris stared.
His hands looked almost normal. Almost. But the nails were too dark, not black anymore, but a deep charcoal gray that caught the light wrong. The skin on his knuckles was too smooth. No scars from the fight. No cuts from the climbing. Just perfect, unmarked flesh that shouldn't exist on a Zone 3 scavenger.
"Kael." Seris's voice was barely a whisper. "What happened to you?"
"I don't know."
"What do you mean you don't know?"
"I mean I don't know." His voice cracked. "I was dying. The Jackals—no, after the Jackals. There was a monster. A Reaper Beetle. It caught me in a dead end. It..."
He couldn't finish.
The memory was too fresh. Too visceral. He could still feel the mandibles closing on his shoulder. Still taste the blood in his mouth. Still hear the wet tearing sound of his own flesh being ripped away.
Seris moved around the table.
She knelt in front of him, taking his hands in hers. Her touch was gentle. Familiar. The hands of someone who'd bandaged his scrapes as a child, who'd held him through fevers and nightmares and all the small horrors of growing up in Zone 3.
"Tell me everything," she said. "From the beginning. Don't leave anything out."
So he told her.
The Jackals. Coll. The courtyard. The fence.
The beetle emerging from the shadows.
The first bite that took his shoulder. The second that opened his chest. The feeling of being eaten alive, conscious, aware, unable to stop it.
Then the words.
**CRITICAL DAMAGE DETECTED**
**ACTIVATING HIDDEN PROTOCOL**
"Protocol?" Seris interrupted. "What protocol?"
"I don't know. It just... appeared. In my head. Like words burned into my brain. It asked if I wanted to proceed. If I wanted to live."
"And you said yes."
"Of course I said yes."
"Then what?"
You describe the pain.
The transformation.
The way your body rebuilt itself from the inside out, cells rearranging, mutations activating, something dormant in your DNA finally waking up after sixteen years of sleeping.
You describe killing the beetle. How your hands changed. How your teeth changed. How you tore into it like an animal and didn't stop until it was dead and you were holding its core.
You describe eating the core.
And you describe the changes that came after.
Seris listened in silence.
Her face was unreadable. The face she used when processing bad news. When absorbing something too big to react to immediately.
When Kael finished, she didn't speak for a long moment.
Finally, she asked: "Can you show me?"
"Show you what?"
"The changes. Your hands. You said they... transformed."
Kael hesitated. Then, slowly, he focused.
He wasn't sure how it worked. There was no manual, no instruction. But something in him understood instinctively, the same way he understood how to breathe or how to blink.
He willed the change.
His nails darkened. Extended. Curved into black chitinous claws, sharp enough to punch through beetle armor. The skin on his hands rippled, and beneath it, faint outlines of subdermal plates became visible.
Seris drew a sharp breath.
"That's enough," she whispered. "Change them back."
He did. The claws receded. The plates faded. His hands looked almost normal again.
Almost.
"Mom and Dad," Seris said quietly.
Kael blinked. "What?"
"The protocol. The hidden DNA. The... whatever this is." She looked up at him, and her eyes were wet. "This is their work. It has to be. They were geneticists. They worked for Helix Corporation before..."
Before they died.
Before the "accident" that Seris never believed was an accident.
"You think they did this to me?"
"I think they gave you something. A failsafe. A way to survive if..." She trailed off. "They knew something. They were scared before they died. I remember. They kept looking at you like... like they were sorry."
"Sorry for what?"
"I don't know." Seris wiped her eyes. "I was twelve. They didn't tell me everything. But I remember Mom saying once that you were special. That you had to be protected at all costs."
Special.
The word felt wrong. Kael didn't feel special. He felt broken. Changed. Wrong.
But also...
Alive.
You remember the system notifications. The ones that appeared during and after the transformation.
**STRAIN TYPE: ADAPTIVE CHIMERA**
**PRIMARY ABILITIES UNLOCKED**
**HUMANITY INDEX: 87%**
You don't tell Seris about the humanity index.
Don't tell her that number scares you more than anything else.
Don't tell her that some part of you, a part that's growing larger by the hour, doesn't care about being human at all.
Some things are better kept hidden.
Even from family.
"What do we do now?" Kael asked.
Seris was quiet for a moment. Then she stood, moving to the small shelf where they kept their few possessions. She pulled out a metal box battered, locked, something she'd kept since their parents died.
"This was theirs," she said. "I've never been able to open it. The lock is genetic. Keyed to their DNA."
She brought the box back to the table and set it in front of Kael.
"Try opening it."
"Why would I be able to—"
"Because whatever they did to you, it changed your DNA. Maybe enough to trick the lock." She pushed the box toward him. "Try."
The box was cold under your fingers.
Old metal. Pre-collapse quality. The kind of thing that cost more than most Zone 3 families earned in a year.
There's a small panel on the front. A scanner of some kind.
You press your thumb to it.
Nothing happens.
Then—
The panel flickered. A soft beep. The lock disengaged with a click.
Kael stared.
"It worked," Seris breathed.
The box was open.
Inside, carefully preserved in protective foam, were three items.
A data chip. Small, military-grade, the kind used for classified research.
A photograph. Faded, cracked. Their parents, younger, standing in front of a building marked with the Helix Corporation logo. And in their arms, a baby.
Kael.
And a vial.
Not stabilizer solution. Something else. Pale gold liquid that seemed to glow faintly in the dim light. A label on the side, handwritten:
**SERIS, WHEN SHE'S READY**
Seris's hand trembled as she lifted the vial.
"They... they made something for me?"
Kael looked at his sister. At the mutation spreading across her skin. At the death sentence she'd been living with for years.
At the vial in her hands that might change everything.
"I think," he said slowly, "we have a lot to learn about what our parents really were."
Outside, the contaminated wind howled through Zone 3's streets.
Somewhere in the distance, a monster screamed.
And in a small shack at the edge of the slums, two siblings stared at the secrets their parents had left behind.
Secrets that would change everything.
