it's a sign of the times

Pairing: Sebastian Sallow x f!MC

Rating: PG

Word Count: 3.2K

Summary: request [paraphrased]: "Rivals-to-lovers Sebastian and MC use a Time-Turner to travel to the future with Ominis in search for a cure for Anne. Instead they find a girl who's the spitting image of MC trying to sneak into the Restricted Section in the 1910s, only she has freckles like Sebastian..."

the 'verse continues in "the train ain't even left the station" [AO3]

“Anne-Marie Sallow!” she calls out. “Just where do you think you’re going?” At once, the three of you freeze. “Did she say ‘Sallow?’” hisses Ominis. “Did I hear that right?” “I – no. No,” Sebastian stammers. “There’s no way that’s what she said.”

“Can you please remind me again why I’m even a part of this harebrained scheme?” you ask for at least the third time.

You’re crouched around a small table in one of the far corners of the upper section of the Library. It’s well past curfew, but since you aren’t technically breaking any rules by avoiding the Restricted Section, you’re currently getting away with your loitering, as do most students who are caught studying after hours this close to final exams.

Only, you’re not studying. You’ve been summoned there by Ominis, who despite being your closest friend at Hogwarts is also a conniving, duplicitous liar who neglected to tell you that this whole thing is Sebastian’s idea.

You watch warily as he turns over a contraband Time-Turner in his hands, inspecting its impossibly small dials and knobs. The golden sands inside the hourglass hypnotically shift back and forth while he reads over its inscriptions and consults the guidebook he’d smuggled out of the Restricted Section earlier that same day.

You have no idea where he managed to get the device – perhaps in one of those vaults along the coast in Cragcroftshire that he’d been exploring during the summer term. However, now he’s got it in his head that perhaps the reason you haven’t been able to heal Anne is that the cure to her curse simply hasn’t been invented yet. Therefore, a quick jaunt several years into the future ought to reveal a way to rid Anne of her illness (and maybe even earn his way back into her good graces).

It’s not the first ludicrous and impractical idea he’s had in the past year, nor will it be the last, but it’s certainly one of the more radical ones.

“Merlin’s beard, I’ve already told you,” Sebastian sighs. “Since we’re going forward in time rather than back, this is an unauthorized use, and in case we get stuck in the future, we might need your ancient magic.”

“So I’m an insurance policy?!” you demand.

“Not so much for Sebastian as for me,” Ominis answers plainly. “He thinks he’s got it all sorted out, but I’m not as sure.”

“I know what I’m doing,” Sebastian interjects.

You huff and roll your eyes. “Need I remind you that using a Time-Turner to go forward is expressly forbidden by the Ministry? It’s only to go back.”

“Loads of people have done it, though,” he argues. “I’ve been reading all about it, it’s well-documented.”

“And they’ve all come back to the present?” you demand.

“Yes,” he snaps. “...For the most part.”

You scoff. Unbelievable.

“Do you two honestly think my magic is just an unlimited get-out-of-Azkaban-free pass?” you hiss. “I have no idea how to manipulate time and space. If we get stuck there, we’re stuck there.”

“I’m sure you’ll figure something out like you always do,” Sebastian mutters distractedly as he fiddles with the Time-Turner.

You glance at Ominis pleadingly and he just shrugs.

“You know we can’t let him go alone, we’ll never get him back,” Ominis reasons.

“Is that such a bad thing?” you grumble.

Sebastian shoots you a warning look before he holds up the Time-Turner for the both of you to inspect.

“I have it set to jump forward twenty years,” he explains. “We’ll have to get cozy before we go, as we’ve all got to be wearing it. Physically, we’ll land precisely where we are now, at the same time of day.”

“What if the layout of the Library changes?” you ask skeptically.

“The castle hasn’t changed in centuries,” Ominis points out. “Compared to its history, two decades is indeed quite short.”

“...Fine,” you finally mumble. “Go on, then. Let’s get this over with.”

The three of you stand in a tight circle in a spot tucked away behind some shelves, hoping to remain hidden there after you make the jump forward in time. Sebastian drapes the thin gold chain connected to the Time-Turner around the three of you; it even seems to stretch and extend in length to fit. Then he murmurs a brief incantation to the enchanted timepiece and spins the innermost piece a whopping twenty times.

Your stomach lurches while it turns over and the world around you seems to spin out of control, almost like one of those Muggle carousel rides you saw once as a child. You can barely make out years and years of students and professors walking around you – through you, even – and countless books sliding on and off the shelves until everything comes to a sudden halt and you fall straight to the floor.

Ominis and Sebastian tumble with you, winded.

“That felt bizarre,” Ominis wheezes. “Where are we? Did we travel anywhere?”

“N-no,” Sebastian breathes. “Everything else just… traveled around us.”

You glance around the Library and see that as Ominis had suggested, it looks largely the same. There are some newer books among those you recognize on the shelves, their spines less creased and dyed with more vibrant colors than those of your time.

One title jumps out at you: Advances in Practical Conjuring, 1900-1910

We’re in the 1910s, you think bewilderedly. We’re in a new century.

Mercifully, the layout of the library seems to be largely unchanged. Rows and rows of dimly lit stacks stretch along the length of the grand room with two winding spiral staircases leading down to the lower level.

Once you catch your breath, the three of you cast Disillusionment on yourselves and huddle together to make your way downstairs to the Restricted Section. Ominis leads the way with his wand extended to search for any lingering students or restless ghosts, having long since proven that his spatial awareness bests both yours and Sebastian’s even without his sight.

Your trio makes it downstairs and past the first row of shelves before Ominis stops in his tracks. Sebastian collides with him and then you knock into Sebastian, causing you both to hiss some choice words at each other.

“What’s going on?” you demand in a whisper.

“Someone just came in,” Ominis explains. “The librarian is at the desk and she hasn’t noticed, but a student is coming down the stairs.”

Sure enough, across the room you see a faint flicker of light and can just barely make out the outline of a small student sneaking down the main stairs – must be a young one, you think, no more than thirteen.

“I think it’s a girl,” you offer. “I can see her just over there.”

“What’s she doing?” Sebastian whispers.

“I’m not sure yet,” Ominis says carefully. “She’s past the desk, the librarian didn’t see – oh, for Merlin’s sake.”

“What is it?” you breathe.

“She’s going straight for the Restricted Section,” Ominis mutters. “Just our luck, I suppose.”

The three of you remain crouched behind the shelf while you watch the girl creep ever closer to your hiding spot. You’re panicking inside your head, wondering what possible seams of the universe might immediately be torn to shreds if she were to spot the three of you, but thankfully she seems single-minded in her mission to gain access to the locked collection of books across the room from you.

“She’s tiny,” Sebastian snorts. “I suppose the young ones are even more bold in the future.”

“Weren’t you about her age when you first started to sneak into the Restricted Section?” Ominis reminds him.

Sebastian insists, “No, I was fourteen. I didn’t go in until Anne was attacked. She’s got to be twelve at most, maybe even a first year.”

“Will you two be quiet?” you hiss. “She’s going to hear you!”

Across the room, the Disillusioned girl pulls a key out of the pocket of her robes and starts to insert it into the lock. A girl her age wouldn’t have mastered Alohomora yet, you think, nor would it be effective on this kind of lock. You have no idea how she managed to get a copy of the key, however.

“Do you suppose we could just go in after her?” Sebastian proposes. “She’s nearly got it open, we should take advantage of that.”

“Are you mad?” you scoff. “We can’t be in there at the same time, we’ll get caught!”

“So what if some little girl from the future sees us?” Sebastian argues. “Why wouldn’t she believe we’re just students from her time doing our own research?”

But before you can further explain to Sebastian how astonishingly stupid that idea is, the girl across the room gasps softly and drops her key to the floor. In front of her, the lock is glowing red as if it’s searing hot.

That’s a new security development from your time, you think. It’s rather lucky the three of you didn’t discover that the hard way.

Immediately, the young librarian leaps from her seat and hustles across the room to the Restricted Section’s gated entrance much faster than Madam Scribner ever would have.

“Hang on…” you say under your breath. “Is that – that’s Sophronia!”

“Who?” Ominis asks.

“Sophronia Franklin, she’s a fourth-year in our time,” you explain distractedly. “She’s always lingering in the library, of course she takes over for Scribner once we finish school.”

“I know her,” Sebastian chimes in. “Tried to get me to play a game of trivia in exchange for returning a book on curse breaking I’d been waiting for. Rather precocious, I thought.”

You glare at Sebastian and he merely rolls his eyes.

“I didn’t mean it in a flirtatious way, I was referring to her choice in books,” he grumbles. “Merlin, you’re protective of her.”

“She’s a sweet girl,” you murmur, appreciative of the fact that Sebastian can’t see you blushing. Truthfully, you don’t think much about Sophronia these days, other than that she absolutely cannot catch the three of you in her Library as she’ll easily understand what you’re up to.

Before you can try to convince the boys to call it quits and return to the present, Sophronia rounds the corner and the girl’s Disillusionment charm melts away in surprise.

“Anne-Marie Sallow!” she calls out. “Just where do you think you’re going?”

At once, the three of you freeze.

“Did she say ‘Sallow?’” hisses Ominis. “Did I hear that right?”

“I – no. No,” Sebastian stammers. “There’s no way that’s what she said.”

“Apologies, Madam,” you hear the girl say with a cheeky lilt to her voice. “I was just looking for a book for my aunt, that’s all.”

Just then, Sophronia leans down to pick up the dropped key and all three of you catch a glimpse of the young girl’s face. She’s probably around twelve, like Sebastian had guessed, but her face… Merlin, she could be your younger sister.

Her slightly-upturned nose is nearly identical to yours, only she’s got a small smattering of freckles across hers. Then there’s her chin, which juts out just a bit like yours does, and you’re too far away to make out the color of her eyes but you’re positive that they’re almond-shaped just like your own.

Now that you think about it, her hair is tied back like you always did with yours when you were younger – braided with a green bow at the end, only her hair is a rich, warm brown color.

“...Is that you?” Sebastian asks softly. “How. How are you doing this?”

“That’s not me, I’m right here,” you remind him.

“Hold on, what am I missing?” Ominis whispers.

“That girl looks exactly like this one,” Sebastian insists. “She’s got her nose, her eyes, her face shape. It’s like there’s a second-year version of her, standing right across from us.”

“We’re twenty years into the future,” Ominis reminds you both. “...What if she’s your daughter?”

You feel like the room is starting to spin around you again, and you find yourself pitching to the side before Sebastian quickly tugs on your arm and pulls you back behind the shelf.

“Do not go daft on us now,” he mutters. “I don’t care if that is your daughter–”

“She’s your daughter too, you know,” Ominis chimes in. “In case you were wondering.”

“Wh… What?” Sebastian stutters, and Ominis gestures for the two of you to listen in.

“Goodness, Miss Sallow,” Sophronia sighs. “You really are so much like your father, always sneaking into the Restricted Section.”

You watch as the girl puffs up her chest proudly, a mischievous smirk on her face that doesn’t strike you as particularly like you at all – but rather Sebastian.

“I’ll gladly take that as a compliment, Madam Franklin,” Anne-Marie says.

“While I respect that you are both voracious consumers of knowledge, he, like you, had little respect for the rules of the Restricted Section,” Sophronia continues. “I’ll have to ask you to leave until you get permission from a professor for relevant research or turn fifteen.”

Anne-Marie is still arguing with the librarian as she’s being escorted out. “Perhaps if you would just let me borrow the book for a while–”

“I’m afraid I’ll also have to give you detention this time,” Sophronia interjects. “I can’t keep looking the other way simply because I owe your mother a favor. This is the third time this term!”

Anne-Marie huffs and folds her arms. “But my godfather–”

“Your godfather is a very busy man who would undoubtedly appreciate it if you spent more time staying out of trouble,” Sophronia finishes, “than trying to emulate your father. In fact, I think Ominis would agree with me that one Sebastian Sallow in this world is quite enough!”

Well, that certainly clears things up.

Sophoronia marches Anne-Marie up the stairs and out of the library. The three of you, having already forgotten your original mission, put your heads together without a word so Sebastian can drape the Time-Turner around your necks and return you to the present.

You collapse in a heap on the library floor, but this time it’s fully empty – even the librarian’s desk light is extinguished. You sit in silence for a few moments, and you and Sebastian don’t dare look at each other. Eventually you force yourself to stand and offer Ominis a hand up, steadfastly ignoring the other boy.

“So,” Ominis finally says, barely concealing his smile. “When exactly is it, do you suppose, that the two of you fall hopelessly in love with each other?”

You both curse at him at the same time, and Ominis throws back his head and laughs.

“Shout at me all you want, but that little girl is proof that the two of you are destined for each other,” he crows. “Oh, how brilliant!”

“Come now, Ominis,” Sebastian says with a nervous laugh. “You don’t seriously think that girl is, what… our child or something?”

“That’s precisely what I think,” Ominous answers, smirking. “You said it yourself, she looks exactly like her mother.”

“Stop!” you interject. “I’m not anyone’s mother, in case you forgot.”

“Perhaps not yet,” Ominis agrees primly. “I imagine it will be several more years before Sebastian makes you one.”

Sebastian goes deeply red while you sputter indignantly.

“Thats – that’s foul, Ominis,” you insist. “It’s untoward to even be talking about this!”

Sebastian folds his arms and raises an eyebrow. “Really? You’re that offended by the very idea of us having a child together? I’m hurt.”

“W-well, I just meant that we shouldn’t talk about things that haven’t yet come to pass,” you explain nervously. “Besides, all that is years away. Decades, even.”

Sebastian glances sidelong at you, and you wonder if you’re imagining the way he looks you up and down.

“Right,” he says slowly. “It’s not like we know anything for sure, obviously.”

“Of course,” you agree. “...I don’t suppose you have any other family members named Sebastian? Distant relatives, perhaps?”

“Why?” he drawls. “Looking to snag a cousin of mine so I won’t be the one to father your children?”

You shove him right into one of the bookshelves, but he laughs like he doesn’t regret it one bit.

“Now now,” Ominis murmurs. “You ought to be kind to your future husband, you don’t want to damage his virility.”

“I have half a mind to put a dent in Sebastian’s virility right here and now to save me some trouble later,” you reply, casually aiming your wand at his groin.

“Have you gone mad?!” he stammers as he takes several steps backward. “Put that thing away!”

“Oh, will you please relax?” you sigh. “We just saw one of your descendants, your ability to procreate is in no danger.”

“You could still put me in the Hospital Wing,” he sulks. “Besides, it’s not just procreation that I use it for.”

Ominis snorts. “Unfortunately, I am intimately aware of that.”

You make a face while Sebastian grins cheekily, offering no apology.

The three of you start to make your way toward the exit into Central Hall, ignoring the weak protests of the prefects stationed outside. As you make your way back toward the Slytherin common room, you all fall silent again, lost in your thoughts.

You aren’t sure how you’re supposed to forget what you saw, you think. In the future, you have a daughter. Her father is Sebastian Sallow, and… and she’s brilliant. Beautiful, courageous, more than a bit headstrong, and as determined as you both are if not more so.

You catch yourself actually grinning, and when you glance over at Sebastian, you see the same expression on his face.

“Anything you care to share?” you ask him.

“I know we probably shouldn’t talk about it,” he starts, “but there is one thing that girl said that I won’t soon forget.”

“What’s that?” you ask.

He’s quiet for a moment, and then he admits, “I heard her say she’s looking for a book for her aunt, and you haven’t got any sisters.”

You smile softly and reach for Sebastian’s hand. “No, I don’t.”

He lets you take his hand in his to give a reassuring squeeze.

“She’s still alive,” Sebastian says quietly. “She… she’s still sick, probably. But she’s still alive in the future. She meets my daughter, and she knows her.”

“She does,” you say. “And – and maybe we don’t quite know how that happens yet, but you can have a little faith, Sebastian. Things will work out the way they’re supposed to, and Anne will be with us for a long, long time. There’s still plenty of time to make things right again.”

He nods wordlessly but doesn’t drop your hand.

Just before you arrive at your common room, Ominis stops in his tracks.

“Hang on… Her name, Anne-Marie?” he asks you. “That sounds like something Sebastian would have picked. How generous of you.”

“Aww,” Sebastian laughs. “You must be so in love with me by then to let me pick the name.”

You grit your teeth and ignore them as you murmur the password to the giant stone snake guarding the door, hoping to get some well-earned rest and be rid of these boys for the night.

“Don’t worry, darling,” Sebastian says as he ducks around you and slips inside the door. “I’ll let you pick the name for the second one, and we can duel for rights to the third.”

You go running off after Sebastian and holler, “You bastard Sebastian Sallow, how many damn children are you expecting?!”

Ominis quickly pulls the door shut behind him and shakes his head.

“Godfather,” he mutters to himself. “I’ll never know peace, will I?”
