Underswap: Stuck in the middle with you

US! Papyrus x OC

Pacifist 10

As the two Skeletons and humans stepped off the ferry Papyrus suddenly grabbed her wrist then called out to his brother and Chara "hey do you two mind going on ahead I have to talk with Artina for a while." Sans and Chara nodded and disappeared down the tunnel while the tall skeleton led her in the opposite direction she blinked and paused for second feeling dizzy before looking up and seeing the twinkling stones from the wishing room.

"this is the only spot I know Undyne isn't watching." Papyrus stated the tall girl stared at him warily why'd he bring her here for? "I'm sorry." he said bluntly causing Artina to blink she open her mouth the skeleton stopped her,

"I'm sorry I for being a jackass not trusting you and ignoring you, I should have just stuck with what my soul's been telling me, instead of my stupid paranoia." Papyrus held his hand out to her Artina looked at it then at him unsure if this was trick,

"You protected Sans even though you barely knew him, spared Alphys knowing she could've killed you, hell you're even keeping that kid in line." he frowned "you even saved my life and instead thank-you I try to kill you, I under-" he cut off by Artina "If your trying say let's start over and put this behind us you're barking up the tree."

she stated he frowned putting hand down "But." Papyrus looked at her curiously "If it means getting Chara back to his grandfather, I am willing to let bygones be bygones." He held out his hand and she did not noticing the little smirk on the skeleton's face when the orange haired girl check for a some kind of prank objects. Before shaking.

"What? think I rigged my hand?"

"Can never be too careful these days, sometimes it's not just pranksters, most people are likely to kill you then befriend you."

"Yeah, I probably should've got around to asking but what's happened to the surface?"

"Oh, boy let's just say what's going on down here, is small potatoes compared with what's happening up there."

Artina put her hand on her chest "I know first hand on what it does to you." she said drifting off a bit Papyrus out opened his mouth but no words came out, what was he supposed to say? "Hey I saw that scar when I changed your clothes the other night what's that about?" he was snapped out of his thoughts by the human calling his "huh, sorry what were you saying?" the tall girl's mint eyes scanned his face curiously hopefully he didn't say that out loud "I said about twenty years ago a Meteor hit sending the surface back into the dark ages."

he waited for her to continue "the climate shifted drastically causing a super storm that wiped out 60% of the population you might have felt it actually remember any tremors or earthquakes?" Papyrus sockets widened when he recalled a huge earthquake ripping through the underground! everyone was sure the ceiling was gonna collapse then everything went calm and back to normal, he looked at her curiously she was standing in the 'at attention' stance that he recognized from his time as a royal guard arms fixed eyes up front no facial emotion she was definitely was soldier at some point.

"Then of course there are the followers of Kwell."

"The what?"

"We're not really sure who or what they are, Mom told me about an old legend from before the war that there were eight mages not seven. the eighth was a dark mage his soul was contaminated stagnant with magic that brought death and misfortune, anyone who was unfortunate enough to get in his web were turned into husks or chimera; which he used as an army to swarm villages and kingdoms, his sole goal was to watch everything burn, so the monsters and humans worked to together and sealed his soul and spirit into a mystic crystal and hid it away."

"I sense an 'until now' coming."

Artina nodded and sighed "twenty years ago and six months before the meteor my brother's parents were archeologists, they were researching the monster human war, they found Kwell's burial site by accident and brought the box it was sealed in back home with them, they called my mother and asked her what the symbols on the ruins and box meant, She told them for their sakes to return the box and forget about it " The tall girl let out a dry laugh.

"But Eleanor my brother's bio mom couldn't contain her curiosity she opened it and the crystal attached itself to her chest absorbed her soul took control of her body," the skeleton swallowed a lump that formed in his non-existent throat. "And her mate?"

Artina looked him up and down not sure what say "when her husband heard her screams he went to help but Kwell tricked and killed him," The orange haired girl winced as she called the rest of the story "my mother woke up to the commotion and found Kwell standing over her bed they decided not to kill her because her unborn child had yet to know fear and disappeared into night."

she finished her story as Papyrus let it sink then realized something "wait if both your brother's parents are gone how…" the tall girl seem to catch on "tell ya later, for now the others are probably wondering where we are." the tall skeleton nodded then led Artina down a tunnel and found them selves just outside the dummy merchant shop just as Sans, Alphys and Chara came out with a familiar red panda monster "ah, hello again Ione." Artina greeted causing the little girl to perk up when she saw the taller human "Miss Tina!" she used her tail to bounce over to the tall girl who caught the monster child in her arms "She really seems to like you." Sans pointed out surprised to see the child so affectionate to someone other then Alphys.

who was silently observing the humans still a little at odds whether she should trust them or not "Yeah kids love me, because I so lively and colorful" Artina deadpanned causing everyone minus the kids to look at her dumbfounded while the tall girl set the Ione down and gave her a pat on the head.

Before she noticed Alphys watching her Artina arch a brow at the head guard "Well now yer certainly looking better, that's good." she said a sliver of reassurance slipping in her inexpressive voice throwing Alphys way off "y-yeah I guess s-sorry about your jacket." she stuttered Papyrus rolled his eyes at this it obvious was the yellow lizard was testing the tall girl's feelings and see if she'd react violently so far she hasn't shown any sort of hostility towards monster…well except for him but that was his own fault for not trusting her "It's fine." the orange haired girl shrugged.

"when I collapsed I thought…you were gonna…"

"Let's makes something clear here, I don't fight people who can't fight back."

"…"

"Only cowards kick someone when they're down, remember that."

Suddenly three short figures tackled Artina two hugged her legs and one more hung off her arm she looked and saw Sans, Chara and Ione, hanging off her while Alphys was giving her this star struck look "So, cool!" they all said in synch needless to say the tall girl was a little weirded out by that one fan is enough having whole club, now that's her second worst nightmare come to life! It got even weirder when Papyrus suddenly hopped on her back his only answer to this was "I felt left out…"

suddenly Chara and Sans let go of her legs, caught off guard by this and the surprisingly heavy skeleton on her back caused Artina to fall over she shut her eyes expecting Papyrus to bail only to get caught off guard again when he shifted so he absorbed most of the impact "damn, sorry I shouldn't have jumped on your back," He lifted them both off the ground somewhat alarmed "Are you alright? Does your back hurt?" that caused Artina to look a him muddled "yeah it's fine, why?" the tall skeleton went silent for a second, before coming up with something

"It's your bones are smaller and very different from me and Sans's" He coughed scratching the back of his skull "so I figured they'd be more fragile?" Papyrus explained hoping she'd buy that however it was true he noted as Artina observed him, he pulled his hoodie sleeve up to show her his ulna and humerus "So that explains it, geez you kidding." the mint eyed girl gently took his arm in her hands to examined it.

The abnormally large bone arm was almost like a regular forearm if he were human you'd think he was soldier or MMA, something that involved lots of strength and muscle…or in Papyrus's case magic and marrow? She gently traced a small healed crack along his an odd feeling to settle in Papyrus's chest his soul felt lighter as he felt her finger over his bare bone it caused a slight pulse of magic to jolt down his spine and through his arm causing Artina to arch a brow at him.

"…Did you just flex?"

"Flex?"

"it's this thing guys do, when they trying to show off to a girl."

He snorted "I'm not showing off to you." the tall rolled her eyes "I never said you were." both of them glared at each other till someone cleared their throat, causing them to yell "what?!" Papyrus and Artina looked up to see Gerson standing a foot away from them "hate spoil yer flirting, but I'd like to get passed ya so I can shop." the skeleton turned orange he retracted his arm and readjusted his sleeve,

while the human blushed the wall suddenly seemed more interesting as both stepped away from each other then noticed their friends were gone "Yer friends snuck away while yer were flirting." the turtle teased causing the two to yell "We weren't flirting!?" before running off to look for their friends leaving the old man to cackle at them "Young love reminds me of my younger years." Gerson mused the dummy nodding along looking at the turtle "so are you gonna buy anything or what?"

Meanwhile

Undyne watched the security monitor with hearts and flowers floating around her as she watched her new ship bicker and tease each other through the cameras, the fish monster spun her chair in a circle while happily squealing "Honey Peach is a go!" throwing her arms in the air only to slowly stop when NTT appeared in the doorway; oddly quiet as he observed the former captain of the royal guard getting all cozy with the taller human, the scientist could see the gears turning as bubble of dread formed in her belly.

"Well this certainly giving me some ideas." the robot mused causing his creator to stare at him warily "w-What k-kind of Id Ideas?" she stuttered as the DJ bot waved her off "Nothing for you worry about Doc," NTT turn to leave "now if you excuse me, I've got a date!~" before the stunned Undyne could ask who the robot was seeing her doorbell rang signaling her friend arrival.
