How they act when they're sick - Ominis, Sebastian, Garreth, Poppy

Ominis Gaunt
Ominis insists he’s fine, which is how you know he absolutely isn’t.
He’s bundled far too tightly on the Slytherin sofa, green knit blanket pulled up to his chin like it personally offended him. His wand rests loosely in his hand, tip glowing faintly as it tracks your movement across the common room. You catch the way it wobbles when you stop in front of him.
“You’re hovering,” he says, voice rough around the edges but fond. “If you’re going to fuss, at least commit to it.”
You press the back of your hand to his forehead without warning.
“You’re hot.”
“I know, love,” he says easily, lips quirking despite himself. “But this is not the time.”
“Oh my god—” you laugh, immediately mortified. “I’m talking about your temperature.”
There’s a beat.
Then he exhales a quiet, wheezy laugh and tips his head back against the sofa. “Merlin, help me.”
“You’re burning up,” you say, gentler now, thumb brushing his temple. “Why didn’t you tell me you felt this bad?”
“Because,” he says, turning his face slightly into your touch, “I hoped if I ignored it, it would go away.”
“That is the worst possible strategy.”
“It’s worked before.”
You make a noise of deep scepticism and reach for the potion vial you’d hidden behind your back. “Drink.”
He frowns. “Is that Pepper-Up?”
“Yes.”
“The one that tastes like regret?”
“Drink,” you repeat.
He does, grimacing dramatically, then immediately reaches for you, fingers curling into the fabric of your sleeve like it’s instinct. You sit beside him without thinking, and he leans in, forehead pressing to your shoulder. His wand slips from his grasp, dimming as it rolls against your leg.
“Stay,” he murmurs, already half-asleep.
You wrap an arm around him, careful, warm, and he relaxes fully—breathing evening out, body heavy with trust. His voice is softer now, words barely there.
“You’re very good at this,” he says. “Being here.”
You smile, brushing your fingers through his hair.
“Get some rest, Gaunt.”
“Mmm,” he hums. “I love you.”
Yeah. You’re not moving anytime soon.
Sebastian Sallow
Sebastian is terrible at being sick.
He insists on sitting up even when he’s clearly dizzy, sprawled messily across his bed with a blanket he keeps kicking off and a glass of water he keeps forgetting to drink. His usual spark is dulled, but it’s still there—flickering stubbornly, like he refuses to let it go out completely.
You hover in the doorway for a moment, taking him in.
“I hate seeing you like this,” you say at last, sitting on the edge of the mattress. “Feels wrong when you’re not being annoying.”
He lets out a weak huff of a laugh. “Wow. That’s how you show concern now?”
“You love it.”
“I do,” he admits easily, then coughs and scowls at his own body like it’s betrayed him. “Don’t get used to this. I’m only quiet because breathing hurts.”
You reach out, pushing his hair back from his forehead. He’s warm—too warm—and he leans into your touch before he can stop himself. When he realises, he doesn’t pull away. Just closes his eyes, lashes resting against his cheeks.
“Stay,” he says, softer than usual. Not a demand. Not a joke.
You stay.
He drifts after that, tension easing from his shoulders, fingers brushing yours like he needs the reassurance without wanting to say it. For once, there’s no teasing, no clever remark waiting in reserve.
Just Sebastian, worn down enough to let you take care of him—and trusting you not to make a big deal out of it.
Tomorrow, he’ll be annoying again.
Tonight, this is enough.
Garreth Weasley
Garreth is talking to himself when you walk in.
He’s pacing the Gryffindor common room with a blanket half-draped over his shoulders, gesturing animatedly as he explains—again—why the concoction simmering in a mug would have worked if he’d just adjusted the temperature. He pauses only to cough, then waves it off like it’s an inconvenient interruption.
“Garreth,” you say flatly.
He turns, eyes lighting up when he sees you. “Oh! Perfect timing—I was just thinking, if I add a dash of—”
“Lay your ass down and drink the tea I made you.”
He blinks.
Once. Twice.
“…You made tea?”
“Yes. Normal tea. No experiments. Sit.”
There’s a moment where he clearly considers arguing. Then another cough hits him harder this time, and the fight drains right out of his shoulders. He lets you steer him toward the sofa, grumbling good-naturedly as he sinks down beneath the blanket.
“For the record,” he mutters, accepting the mug, “I was about to rest.”
“Sure you were.”
He takes a careful sip, nose wrinkling. “Okay, yeah. This is actually really good.”
You tuck the blanket around him properly, and his voice softens without him noticing. “Sorry,” he adds, quieter. “Didn’t mean to worry you. I just thought I could fix it myself.”
“I know,” you say.
He looks at you then—really looks—and smiles, tired but genuine. “Thanks for stopping me before I blew something up.”
“Anytime.”
He drinks the rest of the tea without complaint, eyes fluttering shut as the common room noise fades into the background. For once, Garreth Weasley lets someone else take over.
Even if it’s just for tonight.
Poppy Sweeting
Poppy doesn’t mean to disappear when she’s sick. It just… happens, so she says.
You find her in the Hufflepuff dormitory with the curtains drawn wide, sunlight spilling across the floor in warm stripes. She’s curled beneath a mess of quilts, hair loose, cheeks flushed in a way that has nothing to do with embarrassment this time. There’s a faint, earthy smell in the air—dried herbs, something floral you can’t quite place.
“You look cute, all bundled in the blankets,” you say softly.
She peeks at you over the edge of the quilt, eyes bright despite herself.
“Hehe, yeah.” She coughs immediately after, turning her face away as if embarrassed by the sound.
You sit beside her without comment, smoothing the blankets back up around her shoulders. She relaxes at once, like she’d been holding herself together out of habit rather than comfort.
“I didn’t want to worry anyone,” she admits quietly. “The Puffskeins seemed fine this morning. I thought I could… manage.”
You brush your thumb over her knuckles. They’re warm. Too warm.
“Managing doesn’t mean being alone,” you murmur.
She nods, slow and thoughtful, then leans into your side like it’s the most natural thing in the world. Within minutes, her breathing evens out, lashes resting against flushed cheeks. Her hand stays curled around yours, gentle but certain.
Outside, the castle hums on—students laughing, footsteps echoing—but here, it’s just warmth and sunlight and the steady comfort of being found.
This time, she lets herself rest.
a/n: I may or may not be dwelling into headcanons more often than I should because I enjoyed writing this a lot AUGDASHASJDA

Ominis Gaunt
ଳ You don’t remember when it started, exactly, just that one day Ominis began resting his head in your lap when he got tired. It was easier there, he said, quieter, and you didn’t think much of it because you’ve known each other since the first year, and that’s just how things are between you.
ଳ He naps easily with you, breathing evening out quickly while you read, your fingers slipping into his hair without conscious thought. You’ve done it so many times now that you don’t even look down anymore, just automatically comb through the soft strands while he sleeps.
ଳ Imelda notices once. She pauses, watches the way he leans into you, the way your hand doesn’t stop moving, and tells you that friends don’t usually look like that. You laugh, shrug it off, say you’re just close, but the comment sticks in the back of your mind in a way you don’t like.
ଳ The next time he falls asleep on you, somewhere quiet and hidden away from the rest of the castle, you become painfully aware of how much space he takes up in your life. The weight of his head, the trust in the way he relaxes fully, the fact that he never does this with anyone else.
ଳ Your hand stills mid-motion, and your chest tightens without warning. The realisation doesn’t crash, it just settles, soft and terrifying and undeniable: you’re in love with him, and you might have been for a very long time.
Sebastian Sallow
ଳ Professor Binns is talking, droning on about dates and goblin rebellions, and Sebastian isn’t even in class. You’re half-awake, scribbling nonsense on your parchment just to look busy, trying not to fall asleep.
ଳ Your thoughts drift anyway, landing on Sebastian like they always seem to. You imagine him grabbing your hand and dragging you somewhere reckless, laughing, choosing you without hesitation like he always does.
ଳ You think about what it would be like to go somewhere with him without a plan, without an excuse, just because you want to be together. The idea feels warm and dangerous in equal measure.
ଳ The bell rings and jolts you back into your body, heart racing for no apparent reason. Ominis taps your desk to get your attention, and you blink at him, disoriented.
ଳ It hits you then, sharp and unwelcome. You weren’t daydreaming to pass the time. You were wishing, and that realisation settles in your chest like a secret you’re not sure you’re ready to admit.
Garreth Weasley
ଳ You only agreed to help because he promised to treat you in Hogsmeade if the potion went wrong. Butterbeer, Chocolate Frogs, the usual bribes, and you pretend it’s purely transactional even though you’d have probably said yes anyway.
ଳ Garreth doesn’t actually need much help. He mostly just talks while he works, glancing over every so often to make sure you’re still there, smiling when he catches you watching.
ଳ You sit by the cauldron, chin in your hands, listening to him mutter and fuss and adjust things with careful concentration. There’s something different about him like this, focused and earnest and completely absorbed in what he’s doing.
ଳ The thought sneaks up on you when your guard is down. He looks good like this. Not in a flashy way, just in a quiet, domestic, I like being here with you way.
ଳ Realising you’re in love with him doesn’t feel loud or dramatic. It just feels like acknowledging something that’s been true longer than you’re willing to admit.
Poppy Sweeting
ଳ You’re paired with Poppy again in Beasts class, like you always seem to be. She kneels in the grass without hesitation, sleeves brushing the dirt as she murmurs softly to a nervous Puffskein, all patience and warmth and care.
ଳ You watch the way she smiles when it inches closer, gentle and genuine in a way that makes your chest ache unexpectedly. She looks at creatures like they’re something precious, something worth protecting at all costs.
ଳ It’s then that you realise you’ve been watching her longer than necessary, that your attention hasn’t drifted once. The thought slips in quietly, almost embarrassed, you want her to look at you like that.
ଳ Not just notice you, but care for you with the same tenderness she gives the creatures under her protection. To choose you gently, the way she chooses them.
ଳ She glances back at you then, smiling softly like she’s just noticed you’ve been there all along, and something in your chest stutters. The realisation settles warm and terrifying all at once, and you look away quickly, because once you understand it, you know there’s no going back.
just a quick little set of rainy-day headcanons for some of my favourite hogwarts legacy characters—soft moments, bad jokes, shared umbrellas, and that specific kind of yearning that only seems to happen when it’s raining 🙂↕️🙂↕️🙂↕️

Ominis Gaunt
ଳ He notices the rain first by sound: the way it sharpens, how the air cools, how the cobblestones shift underfoot. Before you can even comment, he’s already adjusted his grip on the umbrella.
ଳ He walks closer—not abruptly, just a careful recalibration. His shoulder brushes yours. Then again. Then stays.
ଳ His hand finds your sleeve because he needs a reference point. Then your wrist. Then his thumb rests at your side, anchoring himself with quiet confidence.
ଳ You tease him—“Not you getting all touchy-touchy with me.”
ଳ He lets out a low chuckle, warm and private, like it’s meant just for you. “You could move away,” he says mildly.
ଳ You don’t. He knows you won’t.
ଳ The rain dulls the world for him; it always has. But your warmth cuts clean through it, a steady presence that makes navigating feel effortless.
ଳ When you finally reach cover, the umbrella dips—but his hand doesn’t move. He only lets go when you do.
Sebastian Sallow
ଳ The rain hasn’t even properly started before he’s grinning, eyes bright like he’s been handed a gift.
ଳ He tilts his head up, squints at the sky, and says, “Is rain like God’s way of orgas—”
ଳ “SEBASTIAN.”
ଳ He howls, genuinely delighted with himself, nearly slipping on the stones as he laughs. “I was going to say release, actually.”
ଳ He was not.
ଳ He runs ahead, spins around, walks backwards just to keep talking, rain plastering his hair to his forehead.
ଳ When thunder cracks, his bravado falters for half a second, just long enough for his hand to grab yours.
ଳ He doesn’t comment on it. Keeps talking like nothing happened. Doesn’t let go either.
ଳ Later, when you’re soaked and complaining, he says, “Worth it,” like it’s obvious. Like you’re obvious.
Garreth Weasley
ଳ The rain hits, and he laughs like it’s been personally sent for him.
ଳ “Oh this is perfect,” he says, already shrugging out of his bag, already spinning you once just because.
ଳ He doesn’t ask before lifting you—just does it, rain splashing up around his boots as he twirls you like the world’s ended and this is all that’s left.
ଳ He kisses you mid-laugh, clumsy and bright and rain-cold, like he can’t help himself.
ଳ Everything about him is excess: the grin, the spin, the way he presses his forehead to yours and declares this a core memory.
ଳ You’re both drenched, hair ruined, robes heavy—and glowing.
ଳ When you finally stumble under cover, he’s breathless, eyes shining, like he’s just lived out a childhood dream.
ଳ His aunt will absolutely scold him for this later. He will not regret it.
Poppy Sweeting
ଳ You both bolt for cover at the same time, laughter cutting off as the roof shields you from the downpour.
ଳ For a moment, there’s only breathing. Rain crashing just beyond reach.
ଳ Your clothes cling, cool and damp, the air charged with something unsaid.
ଳ You glance at her. She’s already looking at you.
ଳ She looks away immediately, cheeks pink, fingers curling into the hem of her sleeve like she’s grounding herself.
ଳ The rain feels closer now—louder. Your heart thuds like it’s trying to be heard.
ଳ When your shoulders brush, she inhales sharply, then lets it out slow.
ଳ Neither of you moves. Neither of you speaks.
ଳ It’s not a kiss. It’s not even a touch. It’s the moment before something changes—and you both know it.
LOOK I know I just posted earlier, but I can't stop writing!!! god forbid a girl waits to post LMAO but seriously I'm not running out of ideas and I might post more headcanons later HASKJDHGASD
