Death and Duality

Summary:

Harry's just a boy with a cupboard for a bedroom, a scar he doesn't understand, and an overprotective magical cat who seems to think Harry needs guarding from everything. But when he's pulled into the world of magic, he finds more than spells and flying brooms - he finds people who care, secrets that refuse to stay buried, and a destiny that's far more complicated than anyone expected.

Also, there's an annoyingly persistent blond boy who keeps showing up wherever Harry goes, claiming they should be friends. Or rivals. Or something in between.

Oh - and the cat? The cat has a past. And claws.

Notes:

I've already planned out the entire story, and it's expected to be around 40 chapters long. I post consistently, but I've got a busy life so it could take a month or so to complete. I hope you enjoy!

Edit: This is a little longer than I thought it would end up being lol (It’ll def be 50+ chapters)

Chapter 1: The Boy and the Cat

Chapter Text

He had forgotten his name.

Time had worn it down, like wind against stone. Once, he had been something more—someone more. But now, he was a cat. Or something like a cat. His fur was dark as soot, his eyes a piercing silver that caught the light like moonlit steel. On his front left leg, a patch of fur grew in a strange, unnatural pattern—thicker, darker, as if hiding something beneath. And across his flank and back legs, faint scars curved like claw marks—no, fingernails. A memory of fire and cold water and the dead that did not stay dead.

He had been searching. Searching for a long time. For what, he couldn’t say. A scent, a sound, a feeling. Something lost. Something precious.

The streets here were quiet, lined with houses that all looked the same. But this one—this street—pulled at him. It hummed with something familiar. He padded silently along the pavement, tail flicking, ears twitching. The air smelled of clipped grass and cold stone, but beneath it was something warmer. A memory. A home. A laugh. A child’s cry. A woman’s voice, soft and bright. A man’s hand, warm and calloused. He could almost see them—but their faces were smudged, like ink blurred by rain.

He stopped in front of a house with a perfectly trimmed lawn and a door painted a dull, judgmental beige. Number Four. He sat, curling his tail around his paws, and stared. He didn’t know why. But he knew he had found it.

Hours passed. Maybe days. He didn’t leave. He watched.

And then, one morning, the door creaked open. A boy stepped out. Small. Thin. Pale. His clothes hung off him like they belonged to someone else. His eyes were too old for his face, and there were bruises on his arms that no child should have.

The cat’s ears flattened. Something inside him stirred—something ancient and fierce.

The boy sat on the step, arms wrapped around his knees. He didn’t cry. He just stared at the ground, as if hoping it would swallow him whole.

The cat crept closer. The boy looked up. They stared at each other for a long moment. Then, slowly, the boy reached into his pocket and pulled out a crust of bread. He held it out with a trembling hand. The cat took it gently, then pressed his head against the boy’s knee.

He didn’t know why. But he would stay. 

He would protect.

Time passed, though the cat did not count it in days or seasons. Only in bruises.

The boy—his boy—grew slowly, like a plant kept in the dark. He was always too thin, too quiet. His clothes never fit. His eyes never sparkled. But he was kind. He always shared what little he had. And he always smiled when he saw the cat waiting for him.

The cat began to bring him things. Bits of food scavenged from bins or stolen from careless windowsills. A half-eaten sausage. A crust of toast. Once, a whole meat pie, still warm. The boy had cried when he saw it. Not from fear. From gratitude. The cat didn’t understand why that made his chest ache.

Sometimes, the boy would talk to him. Whispered words, soft and secret. “They don’t like me,” he’d say. “They say I’m a freak.”

The cat would press against his side, purring low and fierce.

Other times, the boy wouldn’t speak at all. He’d just sit on the back step, arms wrapped around himself, staring at nothing. On those days, the cat stayed close, curling around him like a shadow.

And when the fat boy came, the cat would hiss. Loud. Sharp. Once, he leapt at the boy’s leg, claws out. The fat boy screamed and ran, and the cat sat proudly on the step, tail flicking. The large man with the mustache had tried to kick him once. The cat had dodged, then turned and stared, unblinking. The man had gone pale. The woman—sharp-faced and sour—had muttered about “that blasted stray.” But she never touched him.

The cat watched. Always watched.

And sometimes, when he slept curled beneath the bushes, dreams came. A straight stick in a hand. A voice calling a name—his name? No, a different name. A brother’s laughter. A scream. Cold water. Fire. Darkness. He would wake with his heart racing, claws digging into the earth.

But the boy would be there. And the cat would remember what mattered: Protect.

Years passed. The boy grew. Not much, but enough. His eyes stayed the same—green and haunted. But he smiled more now. He laughed, sometimes. Especially when the cat chased birds or rolled in the grass like a fool.

The boy was older now. 

The cat watched him from the garden wall, tail curled neatly around his paws. The boy was drawing in the dirt with a stick, humming under his breath. There were new bruises on his arms. The cat’s ears twitched.

Soon, something would change. He could feel it. The air tasted different. Something stirred, faint and familiar.

But for now, he watched.

And waited.

And stayed.

Dust drifted down from the ceiling and landed on Harry’s face. He sneezed, the sound muffled by the thin blanket wrapped around him. His head throbbed. His scalp burned where Uncle Vernon had grabbed a fistful of his hair the night before and thrown him into the cupboard under the stairs. He’d hit the wall on the way down. Hard.

He blinked in the dim light, the only illumination coming from the thin crack beneath the door. He knew better than to cry. Crying didn’t help. Crying made things worse. So he lay still, breathing shallowly, waiting for the pain to dull.

Today was the day.

He didn’t know why, but Aunt Petunia always let him out on Sundays. Maybe she felt generous. Maybe she just didn’t want to cook. Either way, it meant he’d get to see the cat again. It had been nearly a week since he’d last seen it—sleek and dark, with silver eyes that seemed to see everything. Sometimes it brought him food. Sometimes it just sat beside him, warm and silent. But it always came.

He missed it.

The cupboard door creaked open. Light flooded in, and Harry squinted up at the silhouette of his aunt. “Get up,” she snapped. “Dudders wants his lunch.”

Harry scrambled out, ignoring the way his legs ached from being curled up too long. He didn’t say a word. He never did. He just nodded and hurried to the kitchen. He made Dudley’s sandwich quickly—ham and cheese, no crusts, just the way he liked it. He added crisps and a fizzy drink, then placed it all on a tray and set it in front of his cousin, who didn’t even look up from the television.

“Now go weed the garden,” Aunt Petunia said, already turning away.

“Yes, Aunt Petunia,” Harry said, and slipped out the back door.

The sun was bright, the air warm. Harry didn’t go for the weeds. Not right away. He darted around the side of the house, heart pounding, eyes scanning the bushes.

“Cat?” he whispered.

A soft rustle. Then silver eyes blinked at him from the shadows. Harry smiled.

Harry ducked behind the hedge, slipping through the narrow gap between the branches. It was a tight squeeze, but he was small for his age—ten years old and still barely filling out the oversized shirt that hung off his shoulders. The bushes scratched at his arms, but he didn’t care. This was his spot. His and the cat’s.

The cat was already there, waiting in the dappled shade. Its silver eyes gleamed as it turned and disappeared into the underbrush. A moment later, it returned, carrying something in its mouth.

Harry’s eyes widened. It was food. Real food. A half of a meat pasty, still warm, wrapped in a napkin. The crust was golden, flaky. It smelled like heaven.

“Where did you get this?” Harry whispered, taking it gently. The cat didn’t answer, of course, just sat down and began grooming its paw like it hadn’t just performed a miracle.

Harry crawled deeper into the hollow, settling into the soft dirt. The cat curled beside him, its tail flicking lazily. Harry took a bite, then another, chewing slowly, savoring every crumb.

“I had the nightmare again,” he said softly, between bites. “The one I always get when I dream.”

The cat looked up, ears twitching.

“It’s always the same. I’m small. There’s shouting. A woman screaming. A man yelling. Then there’s this green light—so bright it hurts. And then nothing. Just cold.”

The cat bumped its head gently against Harry’s arm.

Harry smiled faintly. “Petunia says my parents were drunk. That they died in a car crash after running a red light. But… I don’t think that’s true.” He looked down at the pasty in his hands, suddenly not hungry anymore. “If they ran a red light, then why is the light in my dreams always green?”

The cat didn’t answer. It just pressed closer, warm and solid.

“Maybe she’s wrong,” Harry whispered. “Maybe they weren’t awful. Maybe they didn’t just leave me.”

He trailed off, staring at the dirt. The cat rested its head on his knee, purring softly. Harry sat in silence, the pasty cooling in his hands, the warmth of the cat grounding him like an anchor in a storm.

The creak of the back door made Harry jump.

He scrambled out of the bushes, heart pounding, wiping crumbs from his shirt. The half-eaten pasty lay forgotten in the dirt. The cat stayed hidden, silver eyes watching as Harry stumbled into the garden just in time.

Aunt Petunia stepped outside, arms crossed, lips pursed like she’d just bitten into something sour. “You haven’t weeded a single thing,” she snapped. “Ungrateful little brat. We take you in, feed you, clothe you, and this is how you repay us?”

Harry ducked his head. “Sorry, Aunt Petunia.”

She wasn’t finished. “That doddering madman who left you on our doorstep said you were ours to do with. Ours. We could’ve left you out in the cold, you know. Let you rot. But we didn’t. So you’d better be grateful.”

“Yes, Aunt Petunia.”

She huffed and slammed the door behind her.

Harry let out a slow breath and dropped to his knees in the dirt. He started pulling weeds, hands moving automatically. The cat emerged from the bushes and settled beside him, tail flicking, eyes alert.

“Thanks for not running off,” Harry murmured.

The cat bumped its head against his elbow.

When the garden was finally cleared, Harry brushed the dirt from his hands and went inside. The house smelled like grease and vinegar. He moved quietly through the kitchen, trying to be invisible.

From the sitting room, he heard Uncle Vernon’s voice—low and urgent. “They’re still coming,” he muttered. “More of them. Every day. I’ve burned the lot, but it’s mad, Petunia. Absolutely mad.”

Harry paused, ears straining.

“Just keep destroying them,” Aunt Petunia hissed. “He can’t know about the letters. He mustn’t know.”

Harry frowned. Letters?

He didn’t have time to wonder. He had dinner to make. He fried sausages, boiled potatoes, and steamed peas. He served the plates without a word, placing them carefully in front of each Dursley. Dudley didn’t even look at him.

When they were done eating, Harry slipped back into the cupboard. His stomach growled, but he didn’t ask for food. He never did. Maybe tonight would be a food night.

It wasn’t.

He curled up on the thin mattress, listening to the sounds of the house settling. The cupboard was dark, but he wasn’t alone. He could still feel the warmth of the cat’s fur against his side, even if it wasn’t there.

He closed his eyes and tried not to dream.

— — — 

A week later, Harry woke to the sound of footsteps overhead and the faint creak of the floorboards. For a moment, he lay still, blinking up at the underside of the stairs. Then he remembered.

The letters.

He sat up too fast. The cupboard spun around him, and he pressed a hand to his forehead, waiting for the dizziness to pass. His scalp still ached from where Uncle Vernon had grabbed him last night, but that pain was familiar now—almost expected.

He remembered the first letter he saw. The way it had slipped through the mail slot, thick and heavy, with his name written in curling green ink. Mr. H. Potter, The Cupboard Under the Stairs. He hadn’t even had time to open it before Uncle Vernon had snatched it from his hands.

The shouting. The panic. The way Aunt Petunia had gone pale as milk. Vernon had burned it in the fireplace, muttering about lunatics and freaks. Then more letters came. Dozens. Hundreds. They came through the mail slot, under the door, even down the chimney. Vernon had boarded up the mail slot, nailed planks over the windows, and still they came.

Harry had never seen his uncle so afraid.

He crawled to the cupboard door and eased it open just a crack. The hallway was quiet. No letters on the floor. No rustling paper. Nothing. He sighed and closed the door gently. He was going to have to get creative if he wanted to read one.

He sat back down on the thin mattress, pulling his knees to his chest. He waited in the dim light, listening for the sound of Aunt Petunia’s voice. She’d call him soon. She always did. And when she did, he’d be ready.

Two hours passed before Aunt Petunia’s voice sliced through the silence like a knife.

“You useless boy! Get up and clean the windows—inside and out!”

Harry opened the cupboard door and stepped out, blinking against the light. He didn’t argue. He never did. He just nodded and went to fetch the cleaning supplies.

He started with the inside windows first. He knew her routine—she always checked early in the task, just to make sure he hadn’t snuck off. If he worked quickly and thoroughly now, she’d be less likely to check again later. That meant more time outside. More time with the cat.

He scrubbed the glass until it gleamed, careful not to leave streaks.

He could still remember the last time she’d caught him with the cat. She’d called it the devil and hurled her tea mug at it. The mug had shattered on the patio, porcelain shards flying everywhere. She hadn’t even looked twice. Just told Harry to clean it up before Dudley stepped on a piece.

When the last of the inside windows was done, Harry slipped out the back door with the bucket and rag. The outside windows were worse—splattered with dirt, grime, and what looked like owl droppings.

He frowned. There had been a lot of owls lately. More than usual. They perched on rooftops, on fences, even on the garden shed. He didn’t know why. All he knew was that Aunt Petunia hated them. She hissed and waved her arms whenever one got too close. As Harry worked, he got close enough to a few to pet them. They didn’t flinch. In fact, they leaned into his touch, feathers soft and warm. One owl, a tawny one with bright amber eyes, extended a leg toward him. A small bundle of something was tied to it.

“I don’t have any food,” Harry whispered, gently brushing the owl’s wing. “Sorry.”

The owl hooted softly and flew off. Harry watched it go, heart pounding. Something was happening. Something strange.

He set down the bucket and turned toward the hedge. Time to find the cat. Harry ducked into the hedge, brushing past the branches until he reached the hollow space where the cat always waited. Sure enough, the cat was there, lounging in the shade like it had been expecting him.

“Hey, you,” Harry said, dropping to his knees. “Miss me?”

The cat blinked slowly, silver eyes gleaming in the dappled light.

Harry sat cross-legged in the dirt, brushing a leaf off his shoulder. “You wouldn’t believe the week I’ve had. Letters. Loads of them. They just started showing up out of nowhere. I didn’t even get to read the first one before Uncle Vernon snatched it away.”

The cat’s ears twitched.

“They kept coming, though. Through the door, the chimney, even the fireplace. He burned them all. Boarded up the mail slot. Screwed wood over the letterbox like a madman.”

The cat tilted its head.

“I just… I need to read one. Just one. I need to know what they say. What if they’re from someone who knew my parents? What if they’re important?”

At the word parents, the cat's head perked up sharply, ears forward, eyes alert.

Harry blinked. “What? You understood that?”

The cat stared at him.

He laughed softly. “No, of course not. You’re just a cat. Aren’t you?”

The cat didn’t move. Harry leaned closer, lowering his voice like he was sharing a secret. “Still… if you could understand me, I’d ask you to save one. Just one letter. Bring it to me before they burn it.”

The cat blinked again. Slowly, deliberately, it moved its head up and down.

Harry tilted his head. “Did you just nod?”

No. That was ridiculous. It just looked like it.

He reached out and scratched behind the cat's ear. “You’re a weird one, you know that?”

The cat purred, then stood and hopped out of the bushes, tail flicking behind it.

Harry sighed and sat there for a moment longer, then grabbed the rag and bucket and crawled back out into the sun. Time to finish the windows.

By the time Harry finished the windows, his arms ached and his shirt clung to his back with sweat. He put the bucket and rag away, then slipped inside, careful not to track dirt on the floor. Aunt Petunia would notice.

Uncle Vernon had requested dinner tonight. That was never good. Harry stood in the kitchen, staring at the ingredients Petunia had laid out. Pork chops. Mashed potatoes. Gravy. Steamed carrots. Vernon’s favorites—when they were made exactly right. Harry’s stomach twisted. If Dudley didn’t like it, he’d get teased and chased around the house. If Petunia didn’t like it, she’d yell. But if Vernon didn’t like it…

Harry shuddered and got to work.

He peeled and chopped and stirred, trying to remember everything he’d seen Aunt Petunia do. He didn’t taste anything—he wasn’t allowed—but he tried to make it look good. Smell good. Be good. When it was done, he set the table carefully, placing each plate exactly where it belonged. Then he retreated to the kitchen, standing just far enough away to be ignored, but close enough to be watched.

He waited.

Two bites in, Vernon grunted. Then he set his fork down with a clatter. “This is awful,” he said, voice rising. “Boy!”

Harry flinched and stepped into the doorway.

Vernon stood, face red, jowls quivering. He grabbed Harry by the ear and yanked him forward, shoving his face toward the plate. “Does this look satisfactory to you?” he growled.

Harry whimpered, the smell of gravy and scorched carrots filling his nose.

“That’s not an answer,” Vernon barked, dragging him closer. His breath was hot and sour. “You think you’re clever, don’t you? Think you can ruin my dinner and get away with it?” 

He muttered the rest, low and sharp, just for Harry. Threats. Promises. Low enough that Dudley wouldn’t hear. Then he dragged Harry through the kitchen, not caring when Harry bumped into the counter, the doorframe, the wall. He threw the back door open and shoved him outside.

“Think about what you’ve done,” Vernon snapped. “And maybe—maybe—we’ll be generous enough to let you back in before dark.”

The door slammed shut.

Harry’s eyes burned, but he didn’t cry. He just sat down on the back step, arms wrapped around his knees, staring at the cracks in the concrete. The sun was sinking lower, casting long shadows across the garden. The air was still, heavy.

After a while, he felt a familiar brush against his leg. The cat. It rubbed against him once, twice, tail flicking, trying to get his attention. But Harry didn’t move. He didn’t even register it, not really. He felt too numb, too hollow. Like all the air had been sucked out of him.

The cat disappeared into the bushes.

Harry didn’t look up. A part of him wondered if that was it—if this was the time the cat wouldn’t come back. Maybe it had finally had enough of him too. But then, a few minutes later, he felt it again. A soft nudge against his leg. He looked down.

The cat was back—and it was holding something in its mouth.

Harry blinked. “What…?”

The cat dropped it gently onto the step beside him.

A letter. Thick parchment. Green ink. His name.

His heart stopped. He stared at it, then at the cat. “How… how did you know?”

The cat just blinked at him, silver eyes calm and steady. Harry reached out slowly, hesitantly, like the letter might vanish or the cat might snatch it away. He half-expected to be bitten. But the cat didn’t move. He picked it up.

Mr. H. Potter, The Cupboard Under the Stairs, 4 Privet Drive, Little Whinging, Surrey .

He turned it over. The wax seal was deep red, stamped with a strange crest—something with a lion, a snake, a badger, and a bird. His fingers trembled as he slid one under the flap. He had just started to pull the letter out when the door behind him slammed open.

Uncle Vernon stormed out, face purple, eyes wild. Uncle Vernon’s shadow fell over him like a stormcloud. “Give me that!” he bellowed, lunging for the letter.

Harry stumbled back, clutching it to his chest. His foot caught the edge of the step, and he tumbled backward, landing hard on the ground. The letter fluttered in his hands, crumpling slightly. Vernon was on him in an instant, reaching down with a furious snarl—but before he could grab the letter, a blur of black fur launched itself at his face.

The cat.

It hissed and clawed, latching onto Vernon’s cheeks, scratching wildly. Uncle Vernon shrieked, stumbling back, swatting at the cat as it clung to him like a shadow with claws. Harry scrambled to his feet, heart pounding, and ran. He didn’t get far. A hand grabbed his arm and yanked him back. Aunt Petunia. He hadn’t even seen her behind Vernon.

“Give that to me!” she screeched, ripping the letter from his hands. Her nails dug into his skin, and her grip was rougher than it had ever been before. Her face was twisted with something between fear and rage.

Vernon finally managed to throw the cat off. It hit the ground with a thud and hissed, darting toward Harry. Vernon raised his foot to kick it, but the cat was faster. It ran to Harry’s side, fur bristling, teeth bared, hissing at Petunia.

She recoiled, eyes wide. “That thing—get it away from me!”

In her panic, she shoved Harry forward—right at the cat. He hit the ground hard, elbows scraping the concrete. The cat was beside him in an instant, pressing close, purring low and protective.

Harry wrapped his arms around it, shielding it with his body. “It’s okay,” he whispered. “You’re okay.”

Then a hand tangled in his hair and yanked. Vernon. He didn’t let Harry stand. Just dragged him across the ground, through the back door, down the hall, and to the cupboard. The cat was still in Harry’s arms, hissing and growling, but Vernon kicked the door open and shoved them both inside. The door slammed shut. The lock clicked.

Darkness.

Harry lay on the floor, the cat curled against his chest, both of them breathing hard. They were trapped. Together.

Then Vernon’s voice, low and thick with fury, came through the door. “You’re never coming out.”

Harry froze, curled on the floor, the cat pressed against his chest.

“You’ll never see the light of day again, boy,” Vernon growled. “You’ll get just enough food to keep you breathing. Less than your usual rations. And that thing in there with you—there won’t be enough for both of you.”

Harry didn’t answer. He didn’t move.

“I’d sooner let you starve than let you out. You hear me?”

He heard. He believed every word.

The footsteps retreated. The hallway fell silent. Harry stayed where he was, arms wrapped around the cat, who purred softly against his ribs. He didn’t cry. He didn’t speak. He just lay there, eyes wide in the dark, heart pounding.

He believed it all.

And for the first time in a long time, he felt truly, utterly hopeless.
