Snape's Sorting Hat

The first years always smell like the inside of a trunk. Wool and dust and the faint sourness of fear. I've been doing this for eighteen years and they never change. Small bodies, wide eyes, the occasional tremor in the hands. They file into the Great Hall behind Minerva like ducklings, and I watch them from the staff table with my wine glass and my practiced indifference.

The Sorting Hat sits on its stool, patched and ancient, waiting to do what it's always done. I've never envied it. The thing gets to poke around in their heads for a few seconds and then shout a word. Gryffindor. Hufflepuff. Ravenclaw. Slytherin. Four boxes. Four futures. The children cheer or slump or cry, and the rest of us pretend this isn't the most consequential moment of their young lives.

Tonight is different.

I don't know it yet, of course. I'm too busy cataloging the usual irritations. Potter's brat is somewhere in this crowd, another year older, another year more insufferable. The Weasley clan has multiplied again, I can hear their red heads bobbing in the back. And Minerva is reading names from her list with that particular clipped efficiency she reserves for ceremonies she finds tedious.

"Ashworth, Margaret."

A girl detaches from the line. Blonde, nervous, trips over her own robes. The hat barely touches her head before it shouts "RAVENCLAW" and she scurries off to the blue table, relieved.

I take a sip of wine. The castle's elf-made vintage, nothing special, but it gets me through these evenings. The enchanted ceiling shows a clear night sky, stars wheeling slowly overhead. Someone's charmed the candles to burn a little brighter than usual. Dumbledore's doing, probably. He likes the drama.

"Bones, Susan."

Hufflepuff. No surprise. The Bones family has been Hufflepuff since before the founding. I watch her walk to the yellow table, shoulders straight, chin up. She has her aunt's bearing. That'll serve her well or get her killed, depending on the year.

The sorting continues. I let my attention drift. The staff table is its usual collection of personalities. Flitwick is beaming at every child, bless his tiny heart. Sprout looks like she'd rather be in her greenhouses. Trelawney is pretending to have a vision, which means she's had too much sherry before the ceremony again. And Dumbledore sits in his throne like a benign old lizard, watching everything and revealing nothing.

I've never trusted that man. Eighteen years of service and I still don't know what he actually wants. He says the right things, does the right things, and yet there's always something underneath. A calculation. A plan. I've learned to live with it. We all have.

"Granger, Hermione."

My attention sharpens. The muggle-born girl. I've heard the staffroom chatter, Minerva's quiet pride, Flitwick's excitement. Apparently she's already read all the first-year texts. All of them. The hat considers her for a long moment, long enough that the hall starts to murmur. Then: "GRYFFINDOR."

Of course. Another brave little lion. I watch her walk to the red table, already talking to the girl next to her, already organizing something. That one will be trouble. The good kind, probably, but trouble nonetheless.

The sorting drags on. I finish my wine and consider a second glass. The house-elves have left a bottle within reach, which is either thoughtful or enabling, depending on your perspective. I pour another.

"Lovegood, Luna."

A small blonde girl drifts toward the stool like she's walking underwater. Her eyes are unfocused, her robes slightly askew. The hat touches her head and seems to pause, confused. I've seen that before, with the strange ones. The hat doesn't know what to do with minds that don't fit its categories.

"RAVENCLAW."

She floats off to the blue table and sits by herself. No one moves to make room for her. I file that away. The world is cruel to the ones who don't fit, and Hogwarts is the world in miniature.

More names. More children. More futures decided in seconds. The Sorting Hat has always struck me as a deeply flawed system, but no one asks my opinion. I'm just the Potions master. The greasy git in the dungeons. The one who used to be a Death Eater, which everyone remembers and no one mentions.

I don't mind. Anonymity has its uses.

"Parkinson, Pansy."

Slytherin, obviously. The Parkinson family has been Slytherin for six generations. She walks to my table with a swagger that's already annoying. I'll have her in class tomorrow. That'll be fun.

The sorting winds down. A few more names, a few more children. I'm on my third glass of wine by the time Minerva reaches the end of her list. The hall is full now, four tables packed with students, the noise level rising as friends reunite and enemies pretend not to notice each other.

And then Dumbledore stands.

The hall goes quiet. He has that effect. It's not magic, not exactly. It's presence. The old man knows how to command a room.

"Welcome," he says, and his voice carries without effort. "Welcome to another year at Hogwarts. To our returning students, welcome back. To our new students, welcome home."

I resist the urge to roll my eyes. He says the same thing every year. The children eat it up, of course. They always do.

"I have a few announcements before we feast. First, the Forbidden Forest remains forbidden. I know some of you have been testing that boundary." He pauses, and his eyes flick to the Gryffindor table. "Mr. Weasley, I'm looking at you."

Laughter ripples through the hall. I see the twin Weasleys exchange a look of pure innocence, which means they're already planning something. Those two will be the death of someone, probably each other.

"Second, the third-floor corridor on the right-hand side is off-limits to anyone who does not wish to die a very painful death."

He says this cheerfully, as if discussing the weather. A few first years look alarmed. The older students don't react at all. We've all learned that Dumbledore's warnings are either deadly serious or complete nonsense, and there's no way to tell which until someone gets hurt.

"Third, and most importantly," Dumbledore continues, "I am pleased to announce a new initiative this year. In cooperation with the Ministry of Magic, Hogwarts will be hosting a series of events designed to promote inter-house unity and... let's call it 'social education.'"

I frown. This is new. The Ministry hasn't mentioned anything to me, and I'm on three committees that should have been informed.

"Details will be provided by your Heads of House," Dumbledore says. "For now, I will simply say that participation is mandatory for all students in years four through seven, and strongly encouraged for everyone else. Now, enough talk. Let the feast begin."

He claps his hands and the tables fill with food. Roast chicken, potatoes, vegetables, bread, gravy, the works. The children descend like locusts. I watch them eat and wonder what Dumbledore is playing at.

Inter-house unity. Social education. The words sound innocent enough, but nothing Dumbledore does is innocent. I've known him too long. There's something underneath this, something he's not saying, and I'll have to figure out what before it bites me in the arse.

I catch Snape's eye across the table. He's watching the students with his usual sour expression, but there's something else there tonight. A tension. He knows something.

I'll ask him later. For now, I eat my dinner and watch the children.

---

The feast ends. The students file out, herded by prefects and teachers. I remain at the staff table, nursing my wine, waiting for the inevitable.

Dumbledore approaches. He moves slowly, deliberately, leaning on his wand like a walking stick. The hall is nearly empty now, just a few stragglers and the house-elves clearing the tables.

"Severus," he says. "Walk with me."

It's not a request.

I rise and follow him. We walk through the corridors, past portraits that pretend to sleep, past suits of armor that stand at attention as we pass. The castle is quiet, settling into its nighttime rhythms.

"You're wondering about the announcement," Dumbledore says.

"I'm wondering why the Ministry is suddenly interested in Hogwarts social life."

"Ah. Yes. That." He stops by a window, looking out at the grounds. The moon is rising over the lake, silver light on black water. "The Ministry has... concerns. About the future."

"What kind of concerns?"

"The kind that involve pure-blood families and their attitudes toward muggle-borns. The kind that involve Slytherin house and its reputation. The kind that involve certain students who might be... susceptible to certain influences."

I understand. He's talking about the war. The war that ended eleven years ago but never really ended. The war that's still being fought in quiet ways, in whispered words, in children who grow up hearing their parents talk about blood purity like it matters.

"You want to rehabilitate Slytherin."

"I want to prevent another generation from making the same mistakes." He turns to look at me. His eyes are blue and piercing and utterly unreadable. "I want you to help."

"I'm a teacher, not a politician."

"You're a Slytherin. You understand the house better than anyone. You know its weaknesses, its strengths, its... tendencies."

"And what exactly do you want me to do?"

He smiles. It's not a comforting expression.

"The initiative will involve a series of events. Dances. Dinners. Group activities. Things that force students from different houses to interact. You will oversee these events for Slytherin. You will ensure that our students participate. And you will report to me on what you observe."

"You want me to spy on children."

"I want you to protect them. There's a difference."

I don't believe him. But I've never believed him, and I've still done what he asked for eighteen years. It's easier than the alternative.

"What else?"

"There is one more thing." He reaches into his robes and produces a small object. A stone. Black, smooth, unremarkable. "This was found in the possession of a student last year. A Slytherin. It's a communication device. Old magic. It allows the user to speak to... certain parties."

"Death Eaters."

"Perhaps. The student claimed he found it. I have my doubts."

I take the stone. It's cold in my hand, colder than it should be. There's magic in it, old and dark. I can feel it pulsing against my palm.

"What do you want me to do with it?"

"Keep it. Study it. And if you find others like it, bring them to me."

I pocket the stone. Another task. Another burden. Another secret to carry.

"Is that all?"

"For now." He turns and resumes walking. "Oh, and Severus? The new Defense Against the Dark Arts teacher will be arriving tomorrow. I trust you'll make him feel welcome."

He says this with a particular emphasis that makes me suspicious. The Defense position has been cursed for years. No one lasts more than a year. Dumbledore knows this. He's been using the position to punish people he doesn't like.

"Who is it?"

"An old friend of yours. Quirinus Quirrell."

I stop walking. Quirrell. The man was a joke when I knew him, a nervous wreck who couldn't teach his way out of a paper bag. He'd been traveling, I'd heard. Some kind of sabbatical. And now he's coming back to teach Defense?

"Quirrell is an idiot."

"Quirrell is... changed. I think you'll find him interesting."

Dumbledore continues walking, leaving me standing in the corridor with a cold stone in my pocket and a growing sense of unease. Something is happening. Something I don't understand. And I'm right in the middle of it.

I don't sleep well that night.

---

The first day of term is always chaos. Students wandering the corridors, lost and late. Teachers trying to establish authority. The castle itself seems to groan under the weight of so many bodies, so many voices, so many lives.

I teach my first class at nine. Potions, first years, Ravenclaw and Hufflepuff. The usual mix of eager and terrified. I stand at the front of the dungeon and watch them file in, taking their seats, pulling out their cauldrons and ingredients.

"Today," I say, "you will learn the difference between a potion and a poison. This is not a philosophical distinction. It is a practical one. A potion saves lives. A poison ends them. The difference is often a single ingredient, a single degree of temperature, a single moment of carelessness."

I pause, letting the words sink in.

"I do not expect any of you to become potion masters. I do expect you to learn enough to avoid killing yourselves or each other. If you cannot manage that, I will personally ensure you never set foot in this classroom again. Is that clear?"

A few heads nod. Most are too scared to move.

"Good. Now, who can tell me the three most common ingredients in a basic healing potion?"

Silence. A girl in the front row, the Granger girl's friend, raises her hand tentatively.

"Yes?"

"Dittany, moonstone, and... and... something else."

"Something else. How specific. I can see you'll go far."

She flinches. I feel a flicker of something that might be guilt, but I ignore it. They need to learn. Softness doesn't help anyone.

The class continues. I demonstrate, I lecture, I correct. By the time the hour ends, most of them look like they've been through a war. Good. That's the point.

The rest of the day passes in a blur. More classes, more students, more of the same. I eat lunch in my office, marking essays from the older students, and wonder when my life became this. A teacher. A spy. A man who spends his days grading papers and his nights reporting to a headmaster who may or may not be on my side.

I think about the stone in my pocket. I haven't examined it yet, but I can feel it. A cold weight against my thigh. It's waiting for something. I don't know what.

The second day is when things start to change.

I'm in the staffroom, grading papers, when the door opens and a woman walks in. She's tall, dark-haired, striking in a way that's hard to ignore. She moves with confidence, with purpose, like someone who's used to being noticed.

"Professor Snape?"

I look up. "Yes."

"My name is Ariadne Blackwood. I'm the new... assistant. For the initiative."

"Assistant."

"Headmaster Dumbledore hired me. I'm to coordinate the inter-house events, and I'll be working closely with you."

She smiles. It's a professional smile, but there's something underneath it. Something sharp.

"I wasn't informed."

"The Headmaster said he would tell you. Perhaps he forgot."

Dumbledore doesn't forget anything. This is another test, another piece of whatever game he's playing. I set down my quill and study the woman.

"What exactly are your qualifications?"

"I have a Mastery in Magical Sociology from the Sorbonne. I've worked with the Ministry on youth outreach programs. And I'm a former Slytherin, which I believe will help me connect with the students."

A Slytherin. Of course. Dumbledore wants someone in the house, someone to watch and report. And this woman is his chosen instrument.

"When did you graduate?"

"Nineteen seventy-eight."

Two years before me. I don't remember her. The castle was full of people, then and now. But something about her name tugs at my memory. Blackwood. There was a Blackwood in Slytherin, I think. A boy. Arcturus Blackwood. He died, didn't he? In the war.

"Did you know Arcturus Blackwood?"

Her expression doesn't change, but something flickers in her eyes. "He was my brother."

"I'm sorry."

"Don't be. He made his choices." She pulls out a chair and sits across from me, uninvited. "Now, about the initiative. I've prepared a schedule of events. The first is a masquerade ball, two weeks from now. All students in years four through seven are required to attend. I'll need your help with the Slytherin students."

"Why?"

"Because they won't listen to me. I'm an outsider, even if I was in the house. But they'll listen to you. They respect you, even if they're afraid of you."

"They should be afraid of me."

"Perhaps. But they should also be guided. That's what this is about, isn't it? Guidance. Prevention. Making sure the next generation doesn't make the same mistakes we did."

She's echoing Dumbledore's words. That's not a coincidence. She's been briefed, prepared, turned into a tool. I wonder if she knows it.

"I'll help," I say. "But I have conditions."

"Name them."

"I run my house my way. You don't interfere with discipline. You don't question my methods. And you don't report to Dumbledore behind my back."

She considers this. Then she nods.

"Agreed. I have conditions of my own. You don't interfere with my events. You don't undermine my authority with the students. And you don't lie to me."

"I never lie."

"You're a Slytherin. You lie constantly. But you're also smart enough to know when it's not worth it. So we'll work together, and we'll see what happens."

She stands and offers her hand. I take it. Her grip is firm, her skin cool.

"One more thing," she says. "The Headmaster mentioned you have something of his. A stone. He asked me to tell you that it's time."

"Time for what?"

"For the next phase. He didn't explain. He just said you'd understand."

She leaves before I can respond. I sit in the staffroom, alone, with a cold stone in my pocket and a growing sense that I've been played.

---

The masquerade ball is two weeks away. In that time, I learn more about Ariadne Blackwood.

She's efficient. Organized. She moves through the castle like she owns it, talking to students, making notes, planning her events. The other teachers seem to like her, or at least tolerate her. Minerva approves, which is rare. Flitwick is charmed. Even Snape, who hates everyone, seems to respect her.

I watch her during meals, during staff meetings, during the quiet moments between classes. She's always working, always thinking, always one step ahead. It's impressive. It's also suspicious.

No one is this dedicated without a reason.

I ask around. The older teachers remember her brother, but not her. She was quiet, they say. Studious. Kept to herself. Left school and disappeared. No one knows where she went or what she did. Until now.

The story she tells is plausible. Mastery in Magical Sociology. Ministry work. Youth outreach. But there's something missing. A gap. A hole in the narrative.

I don't trust her. But I don't trust anyone. That's not new.

What's new is the way she looks at me. Like she knows something I don't. Like she's waiting for me to catch up.

---

The night before the ball, I examine the stone.

I've been putting it off. The cold weight in my pocket has become familiar, almost comforting. But I need to know what it is. What it does. Why Dumbledore gave it to me.

I clear my desk, light a candle, and place the stone in the center of the table. It's black, smooth, about the size of a walnut. It doesn't reflect the candlelight. It absorbs it.

I cast a diagnostic spell. Nothing. I cast another. Still nothing. The stone is inert, or it's hiding from me.

I try a third spell, one of my own invention. A probe, designed to reveal hidden magic. The stone shudders. A crack appears on its surface. And then it speaks.

"Severus."

The voice is familiar. Too familiar. It's my own voice, recorded somehow, preserved in the stone. But I never made this. I never spoke these words.

"You're wondering what this is. You're wondering why Dumbledore gave it to you. You're wondering what it means."

The voice pauses. I don't breathe.

"This stone is a key. It unlocks something. Something you've been searching for without knowing it. The next phase, as the Headmaster said. The next step in your journey."

"What journey?"

The stone doesn't answer. The crack widens, and the stone splits in two. Inside, there's nothing. Just empty space. Just a hollow.

I sit there for a long time, staring at the broken pieces. I don't understand. I don't understand any of this.

But I will.

---

The night of the ball arrives.

The Great Hall has been transformed. The tables are gone, replaced by a dance floor and a stage. The ceiling shows a starry sky, and the walls are draped in silver and green, the colors of Slytherin. Ariadne's doing, no doubt. She's been planning this for weeks.

The students file in, dressed in their finest. Robes and gowns, masks and jewels. They look like adults, or like children playing at being adults. Either way, they're nervous. I can smell it.

I stand by the entrance, watching. The Slytherins arrive in a group, as always. Pansy Parkinson, Draco Malfoy, the usual suspects. They're wearing masks, literal ones, but their identities are obvious. They move through the crowd like predators, looking for weakness.

The other houses keep their distance. Gryffindors on one side, Ravenclaws on another, Hufflepuffs scattered throughout. The segregation is instinctive, ingrained. This is what Dumbledore wants to change. This is what Ariadne is supposed to fix.

Good luck to her.

I circulate. I watch. I listen. The students are awkward, uncertain. They don't know how to interact with each other. The war is over, but the habits remain. The distrust. The fear.

Ariadne finds me by the punch bowl.

"Enjoying yourself?"

"No."

"Neither are they. But they're trying. That's something."

"It's nothing. They'll go back to their corners as soon as the music stops."

"Maybe. Or maybe some of them will make connections. Friendships. Something more."

I look at her. "You're an optimist."

"I'm a realist. I know how this works. You plant seeds, you wait, you see what grows. Some of it will be weeds. Some of it will be flowers. But you have to plant."

"And what are you planting?"

She smiles. That sharp smile again. "Possibilities."

She walks away, leaving me with the punch and my thoughts. The music starts. The students begin to dance, awkwardly, hesitantly. I watch them and wonder what Dumbledore is really after.

And then I see her.

A girl. Fourth year, maybe fifth. She's standing alone by the wall, watching the dancers. Her mask is silver, her dress is green. A Slytherin. But there's something different about her. Something that catches my attention.

She's not nervous. She's not awkward. She's observing, like me. Calculating. Waiting.

I move closer. I want to see her face, her eyes. I want to know what she's thinking.

She turns, and our eyes meet.

And I feel it. A jolt. A recognition. Something I can't explain.

She smiles. It's not a friendly smile. It's a challenge.

And I realize, with a certainty that surprises me, that everything is about to change.

---

The ball ends. The students return to their dormitories. The hall is cleaned. I go to my office and pour myself a glass of firewhisky.

I think about the girl. The silver mask. The green dress. The smile.

I don't know her name. I don't know anything about her. But I know she's important. I know she's part of whatever is coming.

The stone in my pocket is cold. The broken pieces are in my desk drawer, waiting. The next phase, Dumbledore said. The next step.

I drink my whisky and wait.

The night is long. The castle is quiet. And somewhere, in the darkness, something is stirring.

Something old. Something new. Something that will change everything.

I can feel it. I can feel it in my bones.

And I'm not afraid.

I'm ready.
