Veritaserum or Dare
A Hogwarts Legacy Fic
Pairing: Sebastian Sallow/MC; Sebastian Sallow/reader
Summary: You and a bunch of your friends are at Hogwarts during Christmas break. Garreth overhears you explaining the muggle game truth or dare and decides to āenhanceā it like one of his potion experiments.
Hilarity and confessions ensue
āWhat afraid of the truth Gaunt,ā Imelda taunted.
Ominis chuckled, āItās not me, itās the rest of you I fear forā¦but if itās truth you guys want donāt say I didnāt warn you.ā
Before anyone could protest he had already downed the vial of veritaserum Imelda was holding out for him.
āWell now you will all see what Iāve had to deal with for 6 years,ā Sebastian said smugly before he drank his vial. He grimaced, āGood luck to us all!ā
The odd circle of friends gathered around the fire of the Slytherin common room look at one another with excitement and apprehension. It was Garreth who suggested Veritaserum or Dare after overhearing you explain truth or dare to Imelda, Natty, and Poppy. How he got everyone to agree - specifically Ominis and Amit - was a mystery to everyone. He was the one who suggested to play in the Slytherin common room as well to ābe as far awayā from his aunts meddling as possible.
āThe only reason I agreed to this is because Sebastian is the one who brewed this,ā you admitted.
Sebastianās cheeks reddened at your compliment and in that moment he was thankful he was seated the closest to the fire. His voice portrayed his usual confidence as he teased, āHere that Weasley? Iām the trusted potionier here!ā
āYea, yea,ā the redhead dismissed, āletās get this started before the effects wear offā¦with how strong this is weāve got what an hour or two tops?ā
The game commenced and after a few rounds everyone was frustrated. Not one person had picked truth. As frustrating as that was at least the dares were amusing:
Amit had to use the disillusionment charm and retrieve one of Professor Garlickās undergarments. When he came back red faced and explained she didnāt own any, the roars of laughter echoed throughout the dungeon.
Natty had to run around the faculty tower in her animagus form without getting caught. Watching a gazelle attempting to go up and down the spiral stairs was too much. She was almost caught because the group of you watching couldnāt stop laughing. Professor Onai stepped out of her room at one point and looked around to find nothing there.
āHearing wild animals in the hallways,ā she said as she looked down at her mug and whistled lowly, āI better slow down on the fire whiskey.ā
As soon as she went back inside the lot of you hauled ass back to the Slytherin common room and only then did you start laughing again.
Natty swatted Amit hard on his shoulder, āDonāt you ever try to mount me like Iām some kind of horse when Iām in my animagus form ever again or Iāll shove your precious telescope so far up you-ā
āIāM SORRY I PANCIKED,ā Amit cried running away from Natty, āYOU KNOW I CANāT RUN FAST!ā
Poppy had to down a shot of fire whiskey that Gareth had pilfered and then try to steal Leanderās toad that he left behind while he went home for the holiday. After several run ins with walls and hiccuping pleas that she would be a better owner than Leander, she finally got him.
āIām *hiccup* keeping him. What kind of soulless *hiccup* git *hiccup* leaves a creature behind,ā she declared before she started crying. It took several minutes of soothing and petting the toad to calm her down. She still cuddled him now and randomly reassured him that he was safe now she would treat him better anyway.
Imelda had to āmakeoutā with a portrait - specifically Sir Cadogan - and she did so with gusto and way too little shame.
āYou know as amusing as all these dares Iāve witnessed tonight are,ā Ominis deadpanned at the group, āwhatās the point of downing vertaserum if we arenāt planning on taking advantage of its effects!ā
No one spoke up.
āFine Iāll start: truth ask me anything,ā he sighed in frustration.
āUmm do you have a crush on anyone,ā Natty piped up, unsure what else to ask.
āHow original,ā he sighed but there was no real venom in his voice, āI suppose if I didnāt have a crush on my girlfriend she would be highly put out donāt you think?ā
The group gasped. You giggled furiously. Sebastian whipped his head around to his best friend, āGirlfriend?! What girlfriend? And wait why is y/n laughing? Did you know he has a girlfriend?ā
āYes and itās not my turn,ā you laughed as you answered strategically
āTraitors! The both of you,ā he exclaimed, āwell who is it?!ā
āSorry, my turn is over and itās my turn to ask,ā Ominis stated simply. He smiled as he heard the uptick of Sebastianās heart. It was too easyā¦might as well make him sweat a bit.
āI think I shall askā¦.Imelda, truth or dare?ā
āTruth, bring it Gaunt, I have nothing to hide,ā she said proudly.
āThe other day I was taking a walk outside, right around Kogawaās office and summoners court,ā Ominis started.
Imeldaās face fell immediately and she looked like she was about to be sick.
āAs I walked past the room where the quidditch supplies are kept I couldnāt help but hear your outcries of distress,ā Ominis grinned as he emphasized outcries, āor was it distress? Or rather the true question: what were you doing in there?ā
Everyone looked at her expectantly. She gripped her mouth until her knuckles were white. She felt like she was going to be sick if she didnāt answer soon. āOh come now Imelda, I thought you had nothing to hide,ā Ominis teased mercilessly.
The serum was burning through her forcing the truth out. In one breath she exclaimed, āI was getting myself off on my broom.ā
There was a beat of silence before everyone lost it. āI told you I wasnāt the one who should be afraid,ā Ominis said smugly.
āI knew how much you loved flying but I didnāt KNOW how much you LOVED flying,ā Natty said in between giggles.
āHow does one even do something like that with a broom,ā Poppy asked innocently confused.
āGood question Poppy,ā Gareth interjected, āI dare you to show us how!ā
All the girls threw pillows at him shouting choruses of, āYouāre disgusting!ā and āHow dare you?!ā
Imelda sat a little straighter, āToo bad. My turns over and you know what Sallow youāve been a bit too quiet.ā
Sebastianās eyes went wide, āSo wait, I didnāt say anything like these guys - all I did was laugh - and youāre after me now?!ā
āAfraid of the truth Sallow,ā Imelda dared, knowing Sebastian never backs down from a challenge.
āAbsolutely not, fire away,ā he declared with forced casualness.
āLast year,ā she started slowly.
You, Sebastian, and Ominis tensed slightly and stole glances at one another.
āThere was a rumor that you took the fall for breaking into the restricted section for this one,ā she nodded her head at you, āWhy?ā
You cut in laughing, āEveryone knows he likes having people owe him favors so -ā
āI thought she was gorgeous and I wanted to both impress and protect her,ā he admitted with a red face, not daring to look in your direction.
As a chorus of āooosā and āI knew itās rang out you reached for the fire whiskey so you could blame your deep red body blush on that instead of Sebastianās admission.
āHey thatās not butter beer,ā Poppy whispered knowing you never touch fire whiskey.
āI know,ā you whispered back right before you downed a huge gulp.
āGareth,ā Sebastian said briskly, determined to get the spotlight off him, āwhoās name do you pant when you get off - anyone here?ā
This is when Sebastian finally looks at you. He has a triumphant grin as heās sure his point is about ready to be proven.
āPoppy,ā Gareth said sheepishly.
Poppy immediately spit her butter beer out and it sprayed all over Amit.
āIām sorry,ā Gareth winced, āI didnāt mean for you to find out my feelings for you this way.ā
He shot a glare at Sebastian at the same time you shouted, āHA! I told you he was never flirting with me that weāre just friends!ā
Sebastian gaped open mouthed between Poppy (who had just taken another shot of fire whiskey herself) and Gareth.
āButā¦but I swear he was all over you and flirting all last year,ā Sebastian doubled down.
āYea I was,ā Gareth explained as he scratched the back of his neck, āI thought if I flattered her she would be able to get me an in with Poppy. Y/n is the first person to gain any headway with her soā¦.ā
āWait a minute,ā Amit piped up, āwhy does it matter to you if he was flirting with her or not?ā
Ominis chuckled, but said nothing.
āYea and why is it so important that Sebastian know that he wasnāt y/n,ā Natty asked knowingly.
āAnd those are the million Knut questions arenāt they,ā Ominis said smugly as he raised his glass of butter beer and took a drink.
āWh- wh- whoās turn is it now,ā you asked in a high pitched voice.
āEveryoneās gone but you sweetheart,ā Gareth said.
āKnock that off Weasley or I swear to Merlin I will curse you so badly your future generations will feel it,ā Sebastian barked.
You could hear a pin drop as everyone turned to stare at him. Everyone, except for you, was holding in so much laughter it hurt.
āDARE,ā you screamed to break the tension, āI will take any dare you throw at me right now!ā
The heads that were turned on Sebastian all creepily turned towards you with that same ācat who got the creamā facial expression. You shuddered as you realized your mistake, and braced for what was to come.
āI DARE you,ā Gareth declared with purpose, āto tell your crush that you like him.ā
Sebastian held his breath. He was torn between loudly protesting and begging Merlin that it was him. All those feelings still when he saw a tear stream down your face - then all he felt was anger.
āLook what you did Weasley,ā he said enraged as he pulled out his wand, ācouldnāt give her a break? Or be more original?ā
āItās okay Iām just scared of rejection and I definitely didnāt want to say these words with an audience but if I donāt say it Iām going to explode,ā you explained quietly as you put a hand on Sebastianās arm to lower his wand.
He turned to face you and you looked up at him through your lashes.
āI love you Sebastian,ā you said in a small voice, āIāve loved you from the moment I saw you in our common room, pacing in concentration nose deep in a book. When you called me a kindred spirit I thought for sure you could see I was a goner. I come with a lot of baggage and weāre so close as friends. I understand if this puts you off and you want space from me.ā
Sebastian just stared open mouthed back at you. He did so a beat too long and you start walking to your dorm while furiously wiping at your face, āIām off to bed. Happy Christmas guys!ā
When you were completely out of the room everyone turned their eyes to Sebastian who was still frozen in place.
āSALLOW YOU ABSOLUTELY ARSE! I MAY FUCK MY BROOM ON OCCASION BUT THATāS NOTHING COMPARED TO HOW BADLY YOU JUST FUCKED UP RIGHT NOW,ā Imelda screeched and cringed at her own admission. Her anger for her friend overriding her embarrassment.
āImelda is spot on Sebastian,ā Ominis sighed in judgment as he pinched the bridge of his nose.
Suddenly he stood up and announced, āSebastian: youāre not allowed back in our room until after youāve fixed this, you utter imbecile. Garreth, you donāt deserve Poppy, but she seems to be into you despite your revelations. Donāt. Muck. It. Up. Sheās not a potion to be experimented with. Natty, Poppy - you two are lovely, never change. Amit: good luck not picturing Professor Garlick naked from now on. Imelda: you fuck your broom, enough said. Now goodnight!ā
Everyone was silently holding their breath as he headed towards his room. Right before he walked out of eye sight he turned around and said, āOh yes, and Sebastian? Iām courting Anne, because I am a man who can express his feelings and do something about them. Iām blind not dumb.ā
After a few moments of silence Garreth shrugged and spoke up, āHe did warn us about him joining in. He was not kidding.ā
āIām - regrettably - a Gaunt. We donāt kid,ā Ominis shouted from the hallway, āand before you comment Iām blind not deaf and you have the shrillest voice Iāve ever heard from a man Garreth!ā
āWhat are you still doing here,ā Amit questioned the still frozen Sebastian.
āI think heās still in shock,ā Natty giggled.
āHEY SALLOW! HAVE YOU BEEN PETRIFICUS TOTALUSED?! NO? THEN GO FIX THIS NOW OR SO HELP ME I WILL HEX YOU MYSELF,ā Poppy threatened.
That snapped Sebastian out of it and he turned to look at Poppy. When he saw the dangerous look in her eyes he scrambled tripping over his feet and took off for your dorm.
āThatā¦was incredibly sexy,ā Gareth said as he slid closer to Poppy, āI knew you had a little Gryffindor inside youā¦.would you liked some more?ā
He wiggled his eyebrows suggestively as Imelda yelled at him and Poppy giggled.
āBuy me a butterbeer first and then weāll talk,ā she said flirtatiously.
Sebastian could barely hear the roar of his friendsā laughter over the rapid beating of his heart. He knocked on your door a couple times before coming in. You were sat on the side of your bed with your back to him.
āGo away Sebastian. I donāt want your pity,ā you said tiredly, āI know Iām a lot to deal with so Iām not surprised and you donāt have to worry I wonāt fawn all over you.ā
Hearing your self deprecating side hurt him to his core and gave him the strength he needed. In a couple quick strides he made it over to face you. Then he said something you did not expect:
āI know you didnāt take the veritaserum,ā he said softly.
āWhat are you talking about,ā you said defensively.
He gave you a knowing look and you sighed, āHow did you know?ā
It was his turn to sigh as he sat next to you on your bed tilting his body to face you.
āBecause I know you. Youāre so caring and responsible I know that there is no way that you would ever risk accidentally letting out theā¦how shall I sayā¦more confidential details about last years events. Which is something I didnāt even think about, no surprise there,ā he reasoned before giving you that lopsided grin that made you weak in the knees, āand I might have definitely seen you put the full vial in your pocket when you thought no one was paying attention. And if thereās one thing I do thoroughly is pay attention to you.ā
āSebastian donāt say things you donāt mean just to make me feel bet - OH MERLIN WHAT ARE YOU DOING,ā you exclaimed as he bent over you to root through your right pocket.
āSee I pay attention,ā he said with a grin before he downed the serum, āJust in case the first batch wore offā¦I need you to know Iām being completely honest.ā
He waited a moment and then stood up to move in front of you. You couldnāt stop the billions of butterflies that fluttered around in your stomach as he crouched down and gently took your hands in his.
Youād never seen him look this serious - well other than his frustrated and angry seriousness from last year. This was different. This was softness and so very vulnerable.
āThe day you came bursting in the great hall out of breath but still maintaining a confidence that showed us all you belong hereā¦I just knew you were special. I was hoping desperately youād be sorted in Slytherin. I chided myself for that. See I know everyone thinks Iām a big flirt but itās not on purpose. I canāt help how naturally charming I am,ā he visibly cringed after he said that last sentence.
You chuckled and gave him a deadpan look.
āOkay yea, maybe youāre right and I am a but arrogant, I heard it then,ā he admitted and shook his head, āregardless, love and those kind of relationships just werenāt on my priority list. Anne and I went through so much. When I wasnāt at Hogwarts I was just trying to survive being around my Uncle and how he treated me. Then when I was here I had my sister and Ominis and my studies - and yes okay being generally popular has been fun. Yep heard it that time too - Merlin I didnāt know I thought so highly of myself!ā
āGo on,ā you encouraged through your soft laughter, ābefore the serum wears off and I donāt believe a word youāre saying.ā
āI know youāre teasing but ouch. Youāre right though. When you came over and spoke to me I called you a kindred spirit because I knew if I said soulmate I wouldāve scared you away. It didnāt make sense to me I didnāt even know you but you felt like home almost immediately. Then you knocked me on my ass and I was done for, I had to do whatever I could to be close to you. I do pay attention. I look for you everywhere when weāre not together. I come up with any excuse I can to be near you. Then when everything went sideways you stayed by me even when I was nasty to you, when I cursed you, when I took more than I gave. I was horrible and I donāt deserve you. You. Beautiful. Incredible. Kind. Feisty. Witty. Intelligent. Wonderful you. I love you darling, Iāve been yours since I laid eyes on you.ā
Tears spilled from your eyes as you lunged forward to capture his lips in a kiss. He responded in kind and as the kiss deepened you grabbed a hold of his shirt and pulled him up onto the bed with you. Neither of you broke the kiss during this, each of you needing the other more than air.
He caged you between his arms and the bed. Then just as suddenly as it started he pulled away looking confused and slightly upset.
Your mind started racing: did you go too far, did he change his mind now that youāve kissed, were you a bad kisser?!
āWait a minute,ā he said slowly processing something as he looked towards your door, āDid Ominis say that heās dating Anne - as in my twin sister Anne?!ā
You burst out laughing underneath him, āYouāre slow, but you get there!ā
While he was distracted you used your legs to flip him over on his back so you were on top straddling him. You smirked as you took in his shocked and reddened face. Thank Merlin for all that galavanting in the highlands, you were a lot stronger than you looked
āNow that Iāve knocked you on your ass again, how about we put Ominis and Anne on hold and focus on you and me, huh,ā you said lowly causing Sebastian to shiver.
He reached a hand out to tuck some of your hair behind your ear and whispered, āMerlin I love you!ā
His face broke out in a devilish grin, āI could get used to this view you know.ā
Normally youād blush and turn into a puddle at his words. Not tonight, not now that you know he feels the same.
āWell then letās experiment and see how many āviewsā we can come up with,ā you said suggestively.
Sebastian gulped but maintained his confidence when he spoke, āI am a sucker for research and experiments. And we do have a lot of time to make up for, donāt we darling?ā
As you both got lost in one another you didnāt hear what was going on outside your door.
āWell I guess Iām not sleeping in my room tonight,ā Imelda sighed, āI mean good on them - about time honestly. However I donāt even want to sleep in this house tonight, Sallow seems like a screamer to me.ā
āYou would know,ā teased Poppy referring to Ominis hearing Imelda having fun with her broom
āThatās it youāre never touching firewhiskey again,ā Imelda scolded as her cheeks heated up, ācan I stay in your room Natty, since Poppy here is being a jerk.ā
Natty put an arm around Imelda and smiled warmly at her.
āOf course you can, my friendā¦just uhā¦leave your broom behind please,ā she joked and then bolted before Imelda could hex her.
āOH COME ON, YOU TOO,ā Imelda shouted as she took off after her back to the common room where Garreth and Amit were still lounging.
āDo you think she gets splintersā¦you knowā¦.there,ā a wide eyed Amit asked Garreth.
āWeasley. You. Are. DEAD,ā Imelda yelled as she pulled out her wand.
āWHY ME,ā he shrieked.
āBecause this game was your damn idea to begin with now stay still you rotten bastard,ā she ordered.
āPOPPY SAVE ME! YOUāRE SCARY ENOUGH ON FIREWHISKEY TO TAKE HER! HELP!,ā Garreth screeched as he ran.
In that moment you broke your kiss with Sebastian. You looked absolutely panicked as you whisper yelled, āOh no Professor Weasley! I can hear her voice coming from the common room she sounds horrified! Merlin sheās going to kill us if she finds us like - Seb why are you laughing? Seb come on this is serious! Sheās got that shrill upset tone she gets when sheās livid.ā
āJust trust me, weāre safe. Now kiss me,ā he promised.
āScrew it, youāre worth all the detentions!ā
With that the two of you became lost in one another once more. It was a Happy Christmas indeed!
