#underswap x reader

Undertale (Vanilla) 🍦

•he secretly finds it incredibly comforting that you smell like him, and that his hoodie now smells like you.

•while he may act nonchalant, seeing you in his blue jacket actually sends his soul into a bit of a flutter. just really gud at hiding it behind his grin.

•this is Classic, so expect immediate and terrible clothing puns

•he won’t even ask for it back, he’ll just use it as an excuse to avoid doing laundry for another week since “you’re already keeping it clean.”

•he loves when you wear it out cuz it gives him a quiet sense of pride that everyone knows you’re with him.

•You’re lounging on the couch, wearing his giant blue hoodie. Sans walks into the room with a ketchup bottle, as he stares at you and grins, a faint blue hue dusts his cheekbones. “y’know, if you wanted to be closer to me, you could’ve just asked for a hug. but hey, it looks better on you anyway.” He plops down next to you, pulling the hood over your eyes and chuckling as you bury your face in his shoulder.

Underswap (Blueberry) 🫐

•Blue’s eye sockets will literally turn into giant stars, for him ts is the highest form of flattery.

•he’ll aggressively compliment you. Telling you how magnificent and perfect you look in his battle body.

•Bro would immediately pull out his phone to take a million pictures to send to Papyrus (who will absolutely tease him later).

•Seeing you in his clothes will make him want to go out and buy you a matching set of your own “battle armor.”

•To Blue, wearing his battle body means you want to be a magnificent guardsman just like him.

•You walk into the kitchen wearing Blue’s blue bandana and his fit. Blue gasps when he sees you, his eye sockets turning into literal giant stars. “M-MAIDEN! YOU LOOK ABSOLUTELY MAGNIFICENT! THE ROYAL BLUE SUITS YOU PERFECTLY!” He rushes over, lifting you into a enthusiastic hug, entirely forgetting about the tacos on the stove. (it burnt af now)

Underfell (Red) 🍫

•Red’s entire skull will turn bright, glowing crimson.

•bro will look away immediately and try to act like he doesn’t care. (tsundere ahh)

•he’ll immediately try to cover up his embarrassment by acting annoyed, even though he’s secretly thrilled.

•He loves the visual reminder that you are his and only his.

•he’ll eventually grab you by the waist, pull you close, and complain that he’s cold now, just to share the jacket with you.

•You’re wearing his heavy black and red jacket, hands buried in the pockets. Red walks in and freezes, his face lighting up like a Christmas tree. “the hell do you think you’re doin’ in my gear, sweetheart? take it off,” he growls weakly. When you shrug and start to unzip it, he lunges forward, grabbing your hands. “tch—whatever, just…keep it on. it looks better on you anyway.”

Swapfell (Blackberry) 🍇

•He loves the look of his dark, elegant colors on you.

•Like Vanilla, he enjoys the fact that you smell like him, but he’d rather dust himself than admit it out loud.

•Bro will look at you, scoff, and tell you that you look ridiculous and sloppy in his attire.

•Inside, his soul is doing backflips.

•To hide his blushing, he would meticulously adjust the collar of his clothed, claiming he’s just “fixing your terrible presentation.”

•You’re working at a desk, wearing Blackberry’s high-collared purple capelet and sweater. He struts into the room, and crosses his arms, a purple blush creeping onto his purple cheekbones. “ARE THOSE MY CLOTHES? YOU LOOK ABSURD–THAT BELONGS TO A LORD, NOT A PEASANT.” He walks over, his gloved fingers gently but firmly turning your chin up. “BUT…I SUPPOSE I CAN OVERLOOK YOUR THIEVERY, FOR A PRICE.” He leans down and kisses you deeply. (sly mf)

Ink 🎨

•Ink will stare at you for a solid three minutes without blinking.

•Depending on his vial levels, he might genuinely forget that those are his clothes first.

•Once he finally realizes what’s happening, he’ll get incredibly excited and want to paint a portrait of you immediately.

•Seeing you comfortable in his things gives him a genuine spike of affection that doesn’t even require his vials to feel.

•His clothes are usually covered in paint, so expect him to apologize if you get dirty, but ofc he’ll think it looks cute on you.

•You’re wearing Ink’s giant, stained brown scarf wrapped three times around your neck, along with his oversized undershirt. Ink steps out of a puddle of ink, takes one look at you, and his eyes cycle through a dozen different shapes and colors. “Oh wow! You look…amazing love! Hold still, the lighting is perfect!” He frantically whips out a sketchbook and a paintbrush, sketching you with a massive, giddy smile. (CUTIE PIE I CAN’T)

Error 🧶

•error.exe has crashed

•while he hates being touched, you wearing his clothes is like a loophole he loves.

•he’ll mutter about how you’re getting your “weird anomaly germs” all over his favorite jacket, but he won’t make any move to take it back.

•like Blueberry, Error might even sew you a matching fit

•he might use his blue strings to gently tug you closer to him just so he can admire how you look in his fit.

•You walk into the anti void, wearing his signature black and blue hoodie. Error immediately glitches violently and crashed. Once he reboots, he glares at you, a heavy yellow blush on his cheekbones. “w-WhAt dO yOu tHiNk yOu’Re dOiNg?! yOu’Re gOnNa…mEsS uP tHe fAbRiC, yOu sTuPiD gLiTcH…” He turns away, but a blue string gently wraps around your waist, pulling you onto his beanbag chair next to him.

X-tale (Cross) ❌

•Cross is surprisingly soft and easily flustered. (CUTIE ISTG)

•Seeing you in his massive, monochrome fluffy jacket will turn his purple cheekbones completely bright violet.

•Cross has lost a lot in his life, so seeing his partner safe and wearing his clothes gives him a profound sense of comfort

•Chara will absolutely roast Cross for how whipped he looks, which only makes Cross blush harder.

•This guy will definitely pull you into a hug just so he can rest his face against the fluff on your shoulder.

•You’re sitting on the floor of your shared room, wearing Cross’s massive black-and-white jacket. Cross walks back from a quick scouting trip with a chocolate bar in hand and stops dead in his tracks, a purple blush spreading all the way to his pinpricks. “I…uh…you look really nice,” he mumbles, rubbing the back of his neck. He clears his throat, and walks over, sitting right behind you and wrapping his arms around your waist. “You…look warm,” he murmurs into your shoulder “Keep it on, please?”

Dream 💫

•Dream will practically glow with positive aura.

•He’ll shower you with compliments like Blueberry, except less aggressive.

•He views the act of sharing clothes as an incredibly intimate, so he’ll feel deeply touched.

•He will playfully treat you like royalty while you’re wearing his golden accents, bowing to you or kissing the back of your hand.

•Dream loves the idea of sharing everything with his partner, bro will happily let you keep whatever you want from his closet.

•You’ve draped Dream’s golden, star-clasped cape over your shoulders while reading a book. Dream walks into the room, and golden warmth immediately fills the air. His eyes soften into pools of pure light, as he walks over quietly, kneeling by your chair, he takes your hand, and kisses your knuckles. “My star…you look absolutely beautiful. If I didn’t know any better, I’d say you’re already my queen”

Nightmare 🌑

•Nightmare would be both smug and possessive once he sees you

•dude is hella possessive, seeing you covered his clothes signals to his entire gang that you are strictly off-limits.

•he tries to feed on negative emotions, but seeing you look so cozy in his sweaters actually brings him a quiet sense of contentment, which he will deny fiercely (tsundere 2.0)

•he’ll use his extra appendages to reel you into his lap, wrapping his dark tentacles around you like a blanket over his clothes.

•bro would smirk and comment on how his dark aesthetic perfectly fits you, treating it as a testament to his good taste.

•You’re wearing one of Nightmare’s regular sweaters. Then you feel a cold, slimy, yet gentle grip around your waist. A cyan eye glows in the dark as Nightmare pulls you flush against his chest. He chuckles, a dark, vibrating sound. “marking your territory love? or just desperate for my scent? either way…it’s a good look on you, don’t take it off.”

Dusttale (Dust) 🌪

•Dust is very attached to his hood, so if he lets you wear his hoodie, then it means he absolutely trusts you more than his own life.

•seeing you in his hoodie makes him feel like his safe space is now your safe space.

•he won’t say much, he’ll just stare at you with a ghostly purple blush, his mind racing with how lucky he is to have you. (bro is down BADD)

•he’ll use it as an excuse to drag you to bed for cuddles, claiming you stole his warmth so you have to replace it. (Red 2.0)

•his loves that your scent mixes in with his clothes (NOT IN A WEIRD WAY) he finds this incredibly comforting, often helping him quiet the manic voices in his head.

•You have Dust’s grey, dust-streaked hoodie zipped all the way up to your nose. Dust walks in, murmuring to his Papyrus, then goes completely silent when he sees you, his purple eye lights flicker. “Papyrus, shut up for a second,” he mutters, walking over to you. He grabs the strings of the hoodie, pulling you close to him “you’re crazy, ya know that? stealing a killer’s clothes, guess I gotta keep an eye on you now.”

Killer 🔪

•Killer will immediately start cackling.

•unlike Error, he has zero concept of personal space, bro will immediately throw his arms around you, and slide his hands into the pockets of the jacket.

•his shirt usually has a giant target on it, so bro would use that to his advantage to make cheesy pick-up lines about you ‘targeting his heart’

•thinks it’s both hilarious and badass, he’ll want to take you out to show the rest of the gang just to mess with them.

•he likes the domestic, normal feeling of a partner stealing his clothes.

•You’re walking through the castle hallways, wearing Killer’s target-printed shirt and jacket. Killer turns the corner and spots you, letting out a loud cackle “whoa, mama! didn’t know I hired a stunt double! you look way better in that than I do, babe.” He jogs over, throwing an arm heavily around your neck, dragging you into a messy side-hug. “c’mon, let’s go see if we can trick Nightmare into thinking you’re me.” (ye bruh ts ain’t working)

Horrortale (Axe) 🍴

•for a second, you might think he’s mad, but he’s actually just completely mesmerized.

•he’ll melt inside the moment he sees you snuggled up in his clothes

•bro would become incredibly gentle, handling you like a fragile glass doll so he doesn’t tear the clothes or hurt you.

•Horror is deeply insecure about his gruesome appearance, so seeing you willingly wear his blood-stained or worn-out clothes reassures him that you truly love him. (MY BABY 😭)

•he won’t say much, but he will walk over and sit down heavily next to you, just to bury his face right into your neck, breathing in your scent mixed with his coat. (again, not in a weird way)

•You are wearing Horror’s giant, heavily stained blue jacket. Horror trundles into the kitchen, and freezes when he spots you, his single red eye light dilates to the size of a saucer. He walks over silently, lifts you off your feet with one arm, and buries his face in your hair “…warm?” he rumbles out softly, you nod, and he lets out a deep, rattling purr, holding you tighter.

Epictale (Epic) 😎

•Epic will immediately react with dramatic anime-style poses. ( son 😭)

•he’ll yell out a catchphrase or act like you’ve ascended to a higher level of coolness.

•his purple trench coat is iconic, and he’ll love seeing you twirl around in it.

•he’d insist on turning it into a runway fashion show, putting his cool shades on your face to complete the look while playing hype music from his phone.

•behind the memes, Epic is a smooth talker, he’ll catch you by the waist, dropping the meme persona for a second, and tell you that you look genuinely beautiful (I swear guyz he’s just a silly nerd-)

•You’re wearing Epic’s long, purple and black trench coat, trailing it along the floor. Epic bursts through the door, and drops the cookie in his hand “BRUH! look at the drip! you look absolutely legendary!” He slides across the floor on his knees, stopping right in front of you. He takes off his purple sunglasses and slides them onto your nose. “yep, officially cooler than me. that’s it, we’re getting married, bruh.”

Fresh 🌈

•his 90s-active sunglasses will flash words like ‘CUTE’

•he doesn’t quite understand human romance conventions, but he finds it “totally radical.”

•be careful though cuz his clothes are blinding

•he’ll use his usual 90s slang to compliment you, calling you a “totally rad bae” while blushing a bright rainbow color.

•even though he’s technically a soul-less parasite, being around you when you look so comfortable in his gear gives him a fuzzy feeling he can’t quite explain.

•You’re wearing Fresh’s neon windbreaker jacket. Fresh skates into the room, doing a kickflip before stopping dead. His glasses that spelled ‘YOLO’ quickly changed to ‘CUTE’. “whoa there, babe! you are totally rocking the fresh style!” He skated over, booping your nose with his finger, and plops his colorful snapback hat onto your head sideways. “now we’re matchin’, totally choice.”

Heya Jellies srry for not posting for a while, this is my first time doing this type of fanfic and I tried making it long so I hope you all like it

Do you guys like the random comments? Is it too cringe? AHH idk if I should do more of this ╥﹏╥

UT! Sans ☆

Rises his eyebrows(?) and smirks a bit wider. With a light blue dusted on his cheek bones, Sans start shooting off as many puns as possible just to make you laugh harder. By the end you can hardly breathe and your face is flush, making it feel warm. Which you really only notice when you go up to your face to message out the soreness from smiling to much.

Thinks its adorable. Probably makes a couple puns about it but would never make fun of you.

UF! Sans ☆

"Damn sweetheart, didn't mean to tickle your funny bone."

His smirk grows into a shit eating grin, showing his sharp teeth a bit more. He goes on for another 10 minutes, wanting to hear what other noises he could possibly get from you. Its only until he's worried that you might pass out from lack of oxygen that he starts to lay off.

He one hundred percent snorts too, doesn't mind it at all. Doesn't mean he won't tease you a little bit though, its just in his nature.

US! Papyrus ☆

Pauses for a second before laughing with you, hard. Don't take it as an insult, Papyrus just thinks its cute. Makes sure to tell you this with a wink too. For the rest of the time spent, he stares with you with a orange glow on his face and a gentle look in his eyes. Makes it a challenge for himself to make you snort as much as possible for the foreseeable future. (Be prepared for a lot of bad puns.)

Alternatively....

Papyrus:

THE GREAT PAPYRUS IS GONNA BE A DAD?? He cannot wait. Absolutely will start researching just like a few other skeletons looking at everything he needs to know about you being pregnant and when the baby is born. Expect long evening s with him. He's quite an active skeleton but he'll do his research and let you snuggle against him. He realizes that you need rest and a lot of it! He will remind you of upcoming appointments you need to go to. He will be the best father ever. He is The Great Papyrus after all. "Sweetheart we don't need all of this..." "YES WE DO I READ IT IN RESEARCH ABOUT FOOD CRAVINGS... WE MUST GET ALL THIS FOOD."

Red:

What did you just say? Your... pregnant? He's happy to have a kid with you but definitely out of everyone he feels the most unprepared to be a dad. He didn't come from the best life and is scared. He doesn't want the baby to grow up like he did only knowing 'kill or be killed' Que in protective Red. He makes sure you don't eat anything you're not supposed to. He reads up about human pregnancies for some help and of course asks you his gorgeous s/o. You will always be taken care of by this secret softie. "Red babe... how many times do I have to tell you that everything will be okay?" "uh.. yea' i know it will. just worried..."

Edge:

He's shocked like some other skeletons. He's happy to have a child with you. He will raise them to be strong and mighty and not fear anything! But for right now the baby is still inside you... for another few months. He'll schedule you any appts you need ultrasounds, prenatal to talk to your doctor or midwife. He will make sure all of your cravings are satisfied no matter how weird they can be! He can sense your anxiety when your anxious about something, so he'll happily help you if you need it. "AH YES WHEN OUR BABY IS BORN, THEY MUST WEAR THIS!" "Baby... we are not putting a collar on our newborn child..." "AND WHY NOT? A COLLAR IN MONSTER TERMS THAT THEY ARE PROTECTED!" "Papy... I'm not putting a collar on my newborn baby and that's final"

Blue: 

He's so excited to be a father! He has experience thanks to raising his little bro Papyrus. Have you guys got everything? Diapers? Check! Bottles? Check! All the other essentials items needed? Check! He needs to make sure nothing goes wrong during your pregnancy. He's heard of the things that can happen when a human is pregnant, and he doesn't want them to happen. "Blue baby... I'll be fine carrying these inside..." "NONSENSE I MUST MAKE SURE MY PREGNANT S/O DOESN'T HURT THEMSELVES!"

Stretch:

He's gonna be a dad? His eye lights would instantly soften as he smiled. He's excited but doesn't exactly show it right away. He'll show it in his actions. Since he's naturally very caring expect him to ask every once in a while, if you need anything. He'll make a lot of dad jokes and stock up on snacks just for you. He loves ya and hopes his actions show that. Expect more cuddles than usual with his phalanges caressing your belly. He'll sing lullabies to your belly as he held it. Yes, he might not be the most energetic partner, but he'll be one hell of a father. "Baby...? what are you doing?" "oh, you know just humming... a lullaby to my baby.."

Bear:

He'll be a little quiet for a bit at first. He's not sure what to say. He's happy and will show in his actions. Throughout your pregnancy you'll find more baby items appearing in your guy's house. If you get discomfort or cravings, he'll give you anything you need. He's more anxious than others and may get anxiety hearing all the bad things that can happen during a human pregnancy. He'll most likely get Papyrus's help building the nursery and crib. He doesn't have the best memory sometimes, but he'll always try his best to remember for you. "Sweetheart I have an appt to go to are you coming with?" "huh..? we have an appt to go to? uh.... yeah i always come don't i?"

Sweets:

He's gonna be a father? He can't wait! He's gonna make sure he gets everything you need for your pregnancy. He wants you to rest as much as you can and please sweetheart eat if you're hungry. He might've come from a world where food was a rarity but if you need anything he'll get you it. Just no sushi. Sorry. He'll build the nursery for you and crib. Expect this big guy to want to touch your baby bump almost every day to keep progress. He'll talk to your belly hoping the baby can hear their father's voice. He's invested for the long run. "DADDY LOVES YOU... SO SO MUCH... LITTLE MIRACLE" "Papy... our baby isn't here yet" "I KNOW... I JUST WANT TO TELL THEM BEFORE THEY'RE HERE"

Dream:

As being the guardian of positive feelings, he is overjoyed to learn that you are pregnant. He would offer any emotional support you needed. Need a hug? He's happy to give you as many as you need. Need some lovings? He'll give you everything you could ever need and want. You would watch him accidently knock over some items in the nursery you guys are making together. He doesn't mean to! He swears! He's just so excited! He's gonna naturally be protective over you and your guy's unborn child. "Dream... will I be a good parent to our child?" "Of course, sweetheart! I believe you will be... you're already the best s/o a skeleton could ever ask for..."

Nightmare:

He's completely shocked. He didn't know a... child could happen but as soon as he knows he gets protective. Welcome in protective Nightmare! Most protective of them all in my case. If Nightmare can't be around then his second closest skeleton he trusts most, Killer is standing nearby you and protecting you. Nightmare makes sure to do his research about human pregnancies after he learns about you being pregnant. He makes sure you get all the rest you need and eat healthy. "dear... what did I say about not too much?" "I'm sorry Nightmare... I just wanted to make myself some food." "couldn't you have made something at least healthier?" "No"

Ink:

He was super shocked and first. Now he's so excited that he ends up throwing up black ink. 100% he is going to have ideas of how to decorate a nursery room and even how to paint the walls. Yes, he can be a bit forgetful at times so you might need to remind his of upcoming appts. He's gonna be the best dad he possibly can be for your child. He's another one who'll be a bit protective over you and making sure you don't hurt yourself. He may not have a soul and need to drink paint to feel emotions. He loves and adores you so much and the same will go with your guys baby. "So.. what should we name the baby Ink?" "Oh! I don't know there's so many to choose from!"

Error:

How and when? Just like classic Sans he didn't know that humans and monsters were compatible. Error doesn't really like being touched a lot so how did this happen between you and him? Well, you're special to him. It took a loooong time before you and Error were physical with each other. Error may be evil but once he learns you're pregnant you're staying with him. No, you cannot go to other AU'S to talk to the other Sans and Papyrus's. Ink may be able to visit but Error is standing close by making sure nothing ever happens to you. He treats you like your glass that'll easily break. "Error... please? I wanna go see the others" "No... YoU'rE mInE... gOtTa PrOtEcT oUr LiTtLe OnE"

Nova:

Acting similar to classic Sans. He's gonna joke around a little more. He can't wait to have a mini him or a mini you running around. He'll start baby proofing the house very early on. He'll joke about sleeping in the nursery. Anything you need from the store? He'll go and grab it for you! He'll read into prenatal things you need. He's not a public display kinda skeleton more private. He'll buy baby clothes for you if you're feeling a bit emotional! He's there for you always and always will be. "what if i mess this up... bein' a father i mean?" "You won't Sans... i just know you won't. You'll be the best dad ever"

Apollo:

He's gonna have a baby! Expect this skeleton to come up with stellar baby names to name your baby. Callisto? Juno? Sol? Orion? All the names he can think of will be named! He'll make baby blankets and clothes to match his outfit. Are you hungry in the middle of the night? That's alright he'll wake up and grab you something! Another skeleton that'll talk to your belly. This baby means everything to him just like you do! He will protect you and your future baby from any cosmic harm or any threats at all. "Baby... are you make another outfit...? We already have 10.. and the baby isn't even here yet." "WE CAN NEVER HAVE TOO MANY MY LOVE!"

Nox:

Now Nox would be a little rough on the outside. Being like kids? Just what I needed. He promises he means no harm by what he said! He does care and he can't wait to have a kid with you. Once he's over the surprised part he'll get protective seeing the world he came from. He had to protect his little brother Rus from other monsters. Hey! Where do you think you're going alone? If you plan on going to the store alone that isn't going to happen anymore. Nox will be beside you at all times. He'll do what he needs for you making sure everything he's doing is right. He might've needed to look up at times how to handle his pregnant s/o mood swings. "BABY I THINK YOU ARE OVEREACTING... ITS JUST BABY CLOTHES" "B-But... look how small they are... I have a baby inside me" Cue the crying s/o as they look at small baby clothes. 

Rus:

Now since you're forgetful, he'll start leaving notes for you everywhere. Reminders for things, times to eat, medicine if you take it. Even notes about how much he loves you! If you don't understand something, blue will explain it to you in a way he'll know you'll understand. You also probably do understand half of stretches jokes, but he doesn't want to explain those to you. That way you both don't have to suffer from puns.

"STAR, DID YOU REME-, OH SO YOU SAW MY NOTE, GOOD!"

Nox knows immediately when you are spacing out, he doesn't mind that you do it at all. He knows that you have a lot on your mind and are always overthinking stuff. However if you are doing it in the middle of something important or something dangerous that could hurt you, he will snap you out of it. Usually nudging your side gets you to snap out of it or just saying your name, if that doesn't work he'll pinch you softly.

Nox is a live you learn type of guy, so at first he thinks you'll learn from being clumsy all the time. Once he realizes, you're not going to, well he starts to take little precautions here and there for you. Though not too many because he doesn't want to treat you like a child. Also one to leave notes for you, once again not as many but ones he knows are important. Maybe a special one once and a while. He'll also double check that you found his notes at the end of the day, just so he knows you got done what you needed to.

Note: "DARLING MAKE SURE TO CHANGE THE LAUNDRY OUT AND TO FOLD THE CLOTHES ON THE BED! MAKE SURE TO EAT ALSO!"

you had gotten in a little tussle with a fallen branch walking home. you were completely oblivious, and tripped right over it. it hurt to walk on, and you soon noticed it swelling. it wasn't... sprained, right? nah, of course not! you brushed it off, thinking that it would be just fine in a day or two.

but until then, you might want to put some ice on that.

and so you did. for three days, with no sign of improvement. you tried keeping it a secret, but then your s/o came home while you were putting ice on it, right on the couch beside the door, and...

UnderTale:

Sans:

-he walks into the house, immediately heading for the couch.

-"hey, y/n, i'm ho- you alright? what happened to you?"

-"oh! sans, hi, i didn't expect you home so early!" you wave frantically to draw his eyes away from your ankle.

-"yeah... work was slow, so i came home. whats going on? you're acting weird."

-"pshh, don't be silly, nothing's wrong! absolutely nothing!"

-he sighs.

-"my whole shtick back in the underground was that i can see peoples stats. your HPs lowered, you're acting really awkward about your leg, and you're trying to hide an ice pack from me. i know, i saw it when i walked in. so, im gonna ask you again. whats going on?"

-you sighed. he caught you, he always did.

-"i dont know what's up. I tripped a few days ago and my ankle just started swelling. I'm gonna give it a few more days before I see a doctor, just to see if it heals on its own."

-"alright then," really? that's it? not going to insist you see someone? well, that's great for you! "I'm going to grillby's. wanna come?"

-you nodded your head.

-"cmon, let's take a shortcut."

-he took you to the fucking ER.

Papyrus:

-you look up after hearing the door open and you heard a crash.

-he had gone grocery shopping, apparently, because his bags were sprawled on either side of him on the floor.

-his jaw was only half hinged, that's how bad you scared him.

-as in it dropped. almost fully.

-he suddenly runs to your side (re-hinging his jaw on the way) and kneels by your side.

-"HUMAN, what ever is the matter? is it serious? does it hurt? will it need stitches? should i take you to-"

-"Paps! i'm okay. i think it's just sprained, i'll be alright," you tries to reassure him.

-"SPRAINED? oh, HEAVENS no, i must take you to the doctor right away!"

-you sigh. "Papyrus, it isn't that big of a deal. i'm sure it'll be alright in a few days."

-"absolutely not! what if it's worse than you think? it could kill you!"

-he really thought a sprained ankle could kill you? he may be clueless about human injuries, but at least he cares!

-you don't have too much time to reply before he picks you up, puts you in the car, buckles you up (because heaven forbid something ELSE happen to you, ESPECIALLY under his watch) and brings you to the ER.

UnderFell:

Sans:

-he literally did not notice.

-he grumbles a quiet, "hey," before trotting upstairs into his room.

-it isn't until several days later when the pain has worsened and you cannot walk on it that he asks what the fuck is going on.

-you explained that you had tripped a few days ago, and it got swollen, and you thought that it would just go away, but it's been getting worse and worse since it happened.

-"fuckin' idiot," he groaned. "i'm dating a goddamn moron! alright, get in the car. i'm takin' you to a hospital."

-he's groaning the entire way.

Papyrus:

-as soon as he lays eyes on you, he sighs.

-"what did you do this time?"

-what the hell did he mean, 'this time'? he CANNOT be holding you accountable for that one time you got a concussion! that was HIS fault!

-"hey! you BETTER not be talking about-"

-"about the concussion," he cut you off. "yes, yes, i'm aware, you believe that incident to be my doing. however, i can GUARANTEE that this is not! now, tell me what happened. i expect a full explanation."

-you rolled you eyes and told him, feeling a little pissed off about his crossed arms and tapping foot, although you couldn't fully blame him. the whole situation WAS a little silly, now that you have to say it out loud.

-he scoffed when you finished talking. such a silly thing! why the HELL didn't you immediately see a doctor? swelling is NEVER normal!

-how did he, a skeleton monster who had gone most of his life without so much as seeing a human, know more about human anatomy than a fully grown human adult?

-and how did he, an esteemed member of the royal guard, end up in a relationship with such a fool?

-"get yourself looking decent. we are visiting the hospital to get you proper treatment."

-'looking decent', you looked fi-! no, you didn't, nevermind.

UnderSwap:

Sans:

-"hey, y/n, Alphys let out training early, so i'm back! what are you doing?"

-you scrambled to hide the ice pack and hike your pants back over your ankle. "oh, uh. . . nothing," you said sheepishly in reply, a fake grin appearing on your face.

-"oohhhh, no no no. i know that look. you're hiding something. best be honest now."

-damn him! how DARE he know you so well!

-"i think i did something to my ankle," you muttered.

-"hmm. . . let me see."

-he walked over and inspected your ankle for a few moments.

-"it looks sprained. when did this start?"

-"a few days ago. i tripped and it started swelling."

-he gave your ankle ankther quick look.

-"and why didn't you tell me?"

-"well, i thought it would go away at first. i was going to tell you, if it didn't. i was just going to wait a few days."

-"well, there's no need! i'm taking you to a doctor."

-he helped you stand and let you use him as something like a crutch, so you wouldn't have to put too much weight on your injured foot.

Papyrus:

-you look up to see him standing, eyebrows furrowed (you know what i mean sans does it in the main game) looking at you.

-"anything you want to tell me?"

-"ah, nothing. . . i'm just gonna go to a doctor if this doesn't start getting better."

-you knew the look he was giving you. he wanted to know what happened.

-"i tripped a few days ago and my ankle started swelling. nothing major. it's just a little sore."

-"mmm. i'm sure. you have five minutes, then i'm taking you to a doctor," he said as he laid on the couch beside you.

-"no, Paps, there's really no need-" you were interupted by snoring. but you knew that didn't mean you were off the hook. he would be awake in five minutes EXACTLY, whether you were ready to go or not.

HorrorTale:

Sans:

-he kinda just stands there for a few moments after he sees you with the ice pack.

-ice pack means something's wrong, because he doesn't see food around, but his skull injury makes figuring anything else out difficult.

-ice pack. . . on your ankle. . .

-it doesn't matter what's wrong. he just knows something is. so, he comforts you! in the only way he knows how!

-which is a BONE-CRUSHING hug.

-and because you're sitting, and he's standing over you, leaning down to hug you, it's a very awkward angle. leading to a lot of bones jabbing into uncomfortable places.

-you know you can't really do anything to get him off of you, so you just wait it out.

-"i'm alright, Sans. it isn't anything major. i'm about to go to a doctor!"

-he was going to tell you to anyway. you just got that part out of the way.

-his time in the underground under Undyne's rule made him very paranoid about the health of those he loves, so no matter how big the injury, you MUST see a doctor.

-it's not up for debate.

-he drives you because he doesn't want you to have to put any more strain on your ankle.

-(should he even have a drivers license? questionable...)

Papyrus:

-he has a puzzled look on his face.

-that. . . he suspected that wasn't a good sign.

-"y/n. . . i don't suppose you want to tell me what is going on?"

-"oh," you nervously laughed. "no biggie. just tripped a few days ago, it kinds hurts. if it doesn't feel better tomorrow i'm seeing a doctor."

-"hmm. i shall hold you to that."

-you laughed. you bet he would.

-spoiler alert, he did.

Clay (Swap Papyrus) doesn't realize he has feelings until they're either pointed out or it hits him in the middle of another task. Once he realizes those feelings he reanalyzes every interaction you've ever had with him to pinpoint when it happened. He confesses casually, no flare or pizzazz. Hell you'd probably barely even notice it if it didn't come out of left field.

Clay is kind of weird when it comes to actually being in a relationship. While he's open with his emotions he's not exceptional at picking up yours. It's a relationship that involves a lot of communication about things that might upset you, you can't just huff around and expect him to know whats wrong or even pick up that you're upset because of him.

Clay isn't jealous at all, nor is he really possessive in any way. He'll step in if somebody is bothering you but its more in a casual "we may or may not be dating" way. He's not super into PDA either but holding hands or having his arm around your shoulders is fine, though he does have a preference for hand holding so he can feel the joints under your skin (he is 100% stimming).

He does want to have Lar's approval before the two of you can actually date, mainly because he knows Lar's is a good judge of character and while Clay believes he's a good judge it never hurts to have an extra pair of sockets looking out for him. You getting along with Lars is either the best case scenario or worse case scenario depending on how many puns and shitty jokes come out of it.

Clay actually really enjoys cuddling, especially if you lay on top of him. He isn't fragile so don't even worry about putting your full weight on him, you're just a really warm weighted blanket. You WILL relax and take a nap with him.

His ideal date is the Aquarium but specifically the underwater tunnels with seating, so you can both just watch the fish go by.

Charoite (Swapfell Sans) is the type to realize he has feelings, come to terms with it, and then ignore it. Hell he never actually confesses. He just wakes up one day and you're sharing a bed and a life together and he goes "Wait a fucking second." Big "do you like me" "we've been married for 10 years" energy in this guy.

Charon likes to make sure you're well fed and taken care of. He'll neglect his own health (often on accident) but he ensures both you and his younger brother are healthy. This ranges from making sure you have breakfast, lunch, and dinner, to reminding you to take a shower or a bath. He is extremely good at balancing greasy indulgent foods with healthy foods, so your meals are always enjoyable.

He's a little bit on the jealous side, though that can be attributed to his life underground, where having a defined romantic relationship often ended in tragedy unless you both were powerful. He tries not to let the jealousy win over reason, but if somebody ignores your boundaries even once they are on his shit list. Possessive as fuck when somebody is trying to flirt with you.

While he loves his brother, he is fully aware that his brother would probably remain uncomfortable around you for a long while. Charon uses his own judgement to decide if you're someone to keep and can get along with his brother or if he should cut his losses as soon as possible. If you do end up getting along he is over the moon.

Charoite loves affection, but any kisses on his face should only be given to the side of his face he actually has feeling on. While he understands the empathetic need to kiss his scars, he'd prefer the kisses be somewhere he can feel them. He also adores nuzzling into you at any possible moment, reputation be damned.

His ideal date is stargazing with a picnic. He's used to constantly being stressed and on the go so something relaxing and low energy is fantastic.

Rust (Swapfell Papyrus) is the type to be afraid to realize and commit to his own feelings. Once he accepts them, however, he'll confess in an extremely romantic way. He's anxious and might be shaking a little while doing it, but he wants to do it properly.

Rust is more of a landscape and environmental artist, but started branching out when he arrived on the surface. He often draws your face specifically in an attempt to get past his face blindness and commit you to memory. It hasn't worked so far, but he's hoping it will someday. Regardless of his ability to remember your face, he has your scent memorized to SOUL.

Rust is absolutely on the jealous side. He's always been an outlier Underground in that he was more passive so once he has something important in his claws he's not letting go. He still tries to keep it under control, but if he even smells the slightest romantic intent from somebody else towards you he'll get possessive. He does try to keep that under control as well, but half of the humans that approach you that way smell absolutely foul and he just can't help himself from resource guarding.

He absolutely wants his brothers approval when it comes to dating you, but is also willing to argue with him. He trusts his brother's judgement but is also well aware of the fact Charoite doesn't trust easily or willingly. It'll be a long long string of awkward family dinners before things relax.

Rus HATES PDA. It makes him extremely anxious and it makes him feel like literally everybody is staring, though this is a bonus when he's feeling possessive. In private he's practically glued to you, hanging off you or playing with your hair or clothes. He is touch starved and even just sitting next to you on the couch makes him happy.
