I’m convinced Sebastian’s a Grower and Ominis is a Shower 🍆
This one just compares the two (and their girlfriends’ reactions), but someday I wanna make a totally silly comic that dives deeper into each—“Grower Sebastian” and “Shower Ominis.”
ominis: put a finger down if you were nice to a girl to use them for your own gain then played yourself, caught feelings, and is now horrendously obsessed with them that you got sick because they chose Amit Thakkar for one charms project
sebastian, on his last finger: i don't like this game
okay not that he needs it but what a ego boost it would be if sebastian stumbled upon mc and ominis talking about the guy she likes and she just like he's so out of my league listing positive traits (cue sebastian getting very jealous) Only for ominis to be like just tell sebastian then I don't have to hear you wine about it all the timee

The stone door of the Undercroft groaned softly as Sebastian pushed it open, stepping carefully inside. He exhaled softly, his shoulders relaxing for the first time all day. He had snuck out after curfew, hoping to release some pent-up frustration with a few dueling spells.
He was halfway down the stairs when he froze. Voices—two of them—floated up from below.
Sebastian frowned, his grip tightening on the banister. He recognized them instantly. You and Ominis.
What were you doing here so late? He edged closer, careful to stay out of sight.
“I just don’t see the point,” your voice echoed softly. “It’s not like anything’s ever going to happen.”
Sebastian froze mid-step, his grip tightening on the banister. His brow furrowed. What wasn’t going to happen?
“It won’t if you keep dragging your feet,” Ominis replied, his tone dry as ever.
“It’s not that simple,” you shot back warily.
Sebastian tilted his head, curiosity sparking to life alongside a strange, uneasy feeling in his chest. You sounded frustrated—almost pained. What could possibly have you so worked up?
“It is that simple. You’ve been in love with him for years,” Ominis said, his tone cutting. “Merlin, I’ve lost track of how many times we’ve had this conversation. Either do something about it, or stop talking about it.”
Sebastian’s heart stopped. In love? You’d never mentioned anyone. Not once.
“There's nothing I can do, Ominis,” you said, exasperated. “He doesn’t see me like that.”
Sebastian’s stomach twisted painfully. Who was this mysterious he? Why hadn’t you told him about this before? You usually told him everything.
“And how would you know?” Ominis challenged.
“Because I know him,” you replied firmly. “We’re best friends!”
Sebastian’s chest tightened, a painful mix of jealousy and confusion swirling inside him. Best friends? You were his best friend. Who could possibly come before him in your life?
“Right,” Ominis said sarcastically. “Because you’re so unremarkable.”
“Ominis,” you groaned, “I’m serious.”
“So am I,” he shot back. “Half the school is in love with you, and you’re acting like you’re some invisible wallflower.”
Sebastian’s jaw tightened. Ominis wasn’t wrong. People were drawn to you—how could they not be? But you’d never seemed to notice, much less care. And now you were sitting here, pouring your heart out about someone who clearly wasn’t him.
You sighed, the sound heavy with frustration and tinged with a hint of defeat. “It doesn’t matter what the rest of the school thinks when he’s completely out of my league, Ominis. With his stupidly handsome face and that ridiculous smile that makes it impossible to think straight…” You trailed off, shaking your head. “Merlin, he’s just… he’s everything. Funny, clever, brave, loyal—he could have anyone he wanted.”
For a moment, it felt like the ground had been ripped out from under Sebastian’s feet. How could you possibly think that? How could you believe, even for a second, that you weren’t good enough for whoever this bloke was? And the worst part—the part that made his chest ache—was that he couldn’t step in. He couldn’t tell you how wrong you were because he wasn’t supposed to be listening this in the first place.
“And?” Ominis prompted.
“And what?” you asked, your voice quieter now.
“You’re always going on about how wonderful he is, which, I’ll admit, I struggle to agree with,” Ominis said with a dry chuckle. “But you never actually tell me how he makes you feel. Isn’t that the important part? Does it matter how... how handsome and funny he is if he doesn't make you feel something special?”
You hesitated, your voice soft and uncertain when you finally spoke. “He… I don’t know. He makes me feel safe, Ominis. Like no matter what’s going on, as long as he’s there, I’ll be okay. And he makes me feel seen. Really seen. Like I don’t have to be the ‘hero of Hogwarts’ or ‘the girl with ancient magic.’ I don’t have to be anything except… me. He knows me in a way nobody else does. And when I’m with him, it’s like—for once—I don’t have to prove anything.”
Sebastian’s chest tightened again, but this time it wasn’t just jealousy—it was something deeper, more painful. Because that’s how he felt about you. You were his safe place, the one person who saw him as more than the brash, reckless troublemaker everyone else thought he was.
And now… now he was realizing that someone else held that place for you.
Ominis huffed a laugh, breaking the silence that followed your confession. “You know, it’s almost tragic.”
You glanced at him, confused. “What’s tragic?”
“That it’s him you’ve fallen for,” Ominis said, his voice laced with dry amusement. “Of all the people in Hogwarts—all the people who would gladly worship the ground you walk on—you’ve managed to lose your head over the most chaotic, reckless, insufferable person I know.”
Your jaw dropped, and a laugh bubbled out of you despite your embarrassment. “Ominis!”
“I’m serious,” he said, smirking. “You could have anyone. Anyone. And yet you’ve decided to pine after someone who probably doesn’t even realize you feel this way because he’s too busy rushing headlong into whatever absurd plan pops into his head.”
You groaned again, shaking your head. “You don’t have to rub it in.”
“Well, I do,” he replied, grinning. “Because clearly, he’s too thick to notice, and you’re too stubborn to tell him. I’m the one stuck in the middle of this ridiculous mess, forced to play mediator while you both dance around each other like idiots.”
Sebastian felt like his chest was going to collapse. The way Ominis spoke so casually about this guy—teasing, almost affectionate—was like a knife twisting deeper into his gut. Whoever you were in love with wasn’t just close to you. They were close to Ominis, too.
Who the hell is it?
Sebastian's mind raced through the possibilities, his thoughts a chaotic mess of jealousy and dread. It had to be someone you spent a lot of time with, someone you trusted enough to feel safe around, someone who was close enough to Ominis that he could make jokes about their recklessness.
And then it clicked.
Garreth Weasley.
Sebastian’s stomach dropped. Of course it was Garreth. It made perfect sense.
Garreth was charming, clever, and funny. He had that easygoing, confident smile that always seemed to draw people in. He was loyal, too—always ready to back up his friends, even if it meant landing himself in trouble. And he had that playful, carefree energy that made everyone want to be around him.
Sebastian felt sick.
Of course she loves Garreth. Why wouldn’t she?
He thought back to all the times he’d seen the two of you together—laughing in the Great Hall, chatting during potions class, exchanging those little looks that he’d tried to tell himself didn’t mean anything.
But they did mean something, didn’t they?
And then there was Ominis. Ominis liked Garreth well enough, didn’t he? He put up with Garreth’s antics, even joined in on the occasional joke. If you were in love with Garreth, it explained why Ominis was teasing you so mercilessly.
It all fit together too perfectly.
Sebastian gritted his teeth. He wanted to hate Garreth—wanted to hate him for being everything Sebastian wasn’t, for being the kind of person you could fall for so easily.
But he couldn’t hate Garreth. Not really. It wasn’t Garreth’s fault that he was so damn likable. It wasn’t Garreth’s fault that Sebastian had been too much of a coward to tell you how he felt.
He pressed his back against the cold stone wall, closing his eyes and letting out a slow, shaky breath.
I’ve lost her, he thought bitterly. I never even had her, and I’ve already lost her.
“It’s not like I have a choice, Ominis,” you continued on, your voice quieter now, tinged with frustration and something far more raw. “If I could stop loving him, don’t you think I would have by now? Believe me, I’ve tried,” you continued, your voice breaking slightly. “I’ve tried everything. I’ve told myself it’s just a stupid crush, that it doesn’t matter, but it does. And no matter what I do, I can’t… I can’t make it go away.”
“Then why don’t you tell him?” Ominis asked, his tone softer now, almost coaxing. “What are you so afraid of?”
You groaned, the sound laden with frustration. “Because it doesn’t matter! He doesn’t like me back, Ominis. I’d destroy our friendship for nothing!”
Sebastian’s heart clenched painfully, the bitter sting of your self-doubt twisting something deep inside him. How could you think so little of yourself? How could you not see what he saw when he looked at you?
Ominis let out an exasperated sigh. “I don’t think he deserves you,” he muttered. “Merlin knows he’s well aware he doesn’t deserve you. But you can’t decide his feelings for him. That’s not how it works.”
You scoffed. “Your point?”
“I’m just saying,” Ominis replied, his tone exasperated, “that you’re doing both of you a disservice. It’s… it’s getting to the point where something has to give. Either you tell him how you feel, or—”
“Or what?” you interrupted, glaring at him.
“Or I will,” Ominis said firmly, his expression unyielding.
You gasped. “You wouldn’t.”
“I would,” Ominis said, his smirk returning. “I’m tired of watching you both suffer in silence. Merlin knows Sebastian’s too dense to work it out on his own. Maybe hearing it outright will knock some sense into him.”
Sebastian’s heart stopped.
It’s me.
The thought hit Sebastian like a stunning spell, freezing him in place as the pieces of the conversation finally fell into place. Every word, every hint, every exasperated sigh from Ominis—it all pointed to the same answer, one that he’d been too blind, too self-critical, to see.
You were talking about him.
You were in love with him.
His breath hitched, and his grip on the banister tightened as his heart pounded so loudly he was certain you and Ominis would hear it. The jealousy, the doubt, the sharp ache in his chest—all of it melted away, replaced by a dizzying mix of disbelief, relief, and something far brighter: hope. Because you loved him.
“I mean it,” Ominis was saying now, his tone both firm and teasing. “If you won’t tell him, I will. Frankly, I’m tired of sitting through these endless heart-to-hearts when the solution is so obvious.”
You groaned, your frustration evident. “Ominis, I swear—”
“Do it, or I’ll make it the most public confession Hogwarts has ever seen,” Ominis threatened, though the smirk on his face made it clear he was only half-serious.
Sebastian couldn’t stay silent any longer. His feet moved before his mind caught up, carrying him down the remaining steps until he was standing in the open, his gaze fixed on you.
“Ominis won’t have to say a word,” he said, his voice steady despite the storm of emotions churning inside him.
You and Ominis both turned toward him, your expression contorting into shock while Ominis grinned.
“Sebastian,” you breathed, your eyes wide.
Ominis crossed his arms, looking entirely too smug. “Ah, there you are."
Sebastian ignored him, his focus entirely on you. “Is it true?” he asked, his voice softer now, almost hesitant. “Everything you just said… is it true?”
Your mouth opened, but no words came out at first. Your gaze flickered to Ominis, as if silently cursing him, before returning to Sebastian. “How much did you hear?”
“Enough,” he admitted, taking a step closer.
You flushed, your hands twisting nervously at your sides. “Sebastian, I—”
“Just tell me,” he interrupted gently, his eyes searching yours. “Please.”
You hesitated for a moment, your breath hitching, before finally nodding. “Yes."
For a moment, Sebastian couldn’t speak. He just stood there, staring at you, his heart so full he thought it might burst. And then, without thinking, he reached for your hands, his grip firm but gentle.
“You’re in love with me?”
Your cheeks burned, but you held his gaze, your voice trembling as you said, “I am."
“I love you, too,” he said simply, the words spilling from his lips like they’d been waiting years to be spoken. “I’ve loved you for as long as I can remember."
Tears welled in your eyes as you stared at him, your expression a mix of disbelief and overwhelming relief. “You… you do?”
He smiled, his thumb brushing lightly over the back of your hand. “I do. More than anything.”
Ominis cleared his throat loudly, breaking the moment. “Well, now that that’s settled, perhaps you two can finally stop making my life so unbearably dramatic.”
Sebastian shot him a look, but there was no real anger behind it. For once, he was too happy, too relieved to care about Ominis’ meddling.
For a moment, neither of you moved, the weight of everything left unsaid finally lifted. And then, with a soft, almost hesitant smile, Sebastian tilted his head and closed the remaining distance, his lips meeting yours in a kiss that was as gentle as it was certain.
When the kiss broke, Sebastian rested his forehead against yours, his smile soft but unshakably certain. “You’re stuck with me now,” he murmured, his voice low and full of promise. And as you laughed, the sound light and filled with a joy you hadn’t felt in years, you knew there was nowhere else you’d rather be.
