Two things about this AU:

First, Papyrus and Sans are age swapped (Papyrus is the elder.)

Second, Sans has more than one HP, more on that later; for now enjoy.

Chapter 6

Somewhere in the multiverse someone put a stamp on it:

...and shipped it like_™.

The chopper came into view again, bringing with it noise and dust which sent Jerry running for the cover of Undyne's SUV. The aircraft was an early model Sikorsky UH-60 Black Hawk, while the outside revealed its age and combat use; though this had been remedied somewhat, because it had been lovingly repainted the with the colors of the Royal House of Dreemurr, and the Delta Rune Shield had been artfully sketched on the tail, just fore of the serial number. The helicopter hovered over the trio's heads for a moment, before making a graceful landing in the gore; a familiar face jumped out before the aircraft actually hit the ground.

"Wahaha, you whippersnappers call for Justice," the Hammer, wearing a flight helmet instead of his usual pith helmet hollered over the throaty thrum of the engine and the high pitched whistle of the rotors cutting through the air.

"Oi, ol' man, what the hell you doing here," Undyne hollered over the constant beating of the rotors, leaning on her spear.

"King Fluffybuns was concerned you youngins couldn't handle squat. And Undyne, I thought you might be after the mailman again," Gerson guffawed loudly, but it swiftly became a cough. The triumvirate headed for the helicopter: Undyne in the lead spear hefted across her back, its ultramarine glow looking greener than usual; Papyrus, bathed in a glow of orange and titian looking like the reaper himself; Alphys trailing apprehensively behind, carrying her laptop. As soon as they were all onboard, Undyne slid the door closed and gave Monster Kid the signal to take it up.

The interior of the aircraft was much more impressive than the exterior. There was ample seating behind the cockpit, brown leather benches replaced overused cloth; with enough room for six passengers. Though, the cockpit itself was the real gem, outfitted with with the latest in computer technology thanks to Alphys and Sans' efforts. Most of the care put into the interior was all Monster Kid, he really cared about his baby, and it showed as the entire console glowed with his magic; a beautiful golden brown. The joystick had been replaced with foot pedals that gave the craft a nimbleness in the air that MK still, occasionally, lacked on the ground. The young pilot, handicapped though he may be; had upon their arrival on the surface, seen the sky and known somehow he had to soar among the clouds. When Frisk had been kind enough to share her books about aviation with him, there was no going back, he knew what he wanted to do with his life.

"Sure thing Boss Lady," MK shouted over the engine's din while using his foot to toss Undyne her headset, before once more ascending to the sky. Alphys had taken the shotgun position and was feeding the tracking data to the flight computer, before grabbing her own headset. Neither of the female monsters were realistically able to wear a flight helmet, though each of their male companions had one. Of course, Sans and the Ambassador each had their own, which were hanging above their vacant seats.

"That armless kid is one hell of a pilot, is that the same lil weirdo that used to follow you everywhere, 'Dyna," the Hammer asked as soon as her headset was situated on her head.

"Cut the crap ol' man! Squirt what's the ETA?" Monster Kid circled the area where he had picked up his superiors and made sure to buzz the crowd of humans near the edge of the roadway.

"Thanks, I'll take that as a compliment, ya crazy old dude, couple o' shakes o' the King's tail if Alphys' data is correct." Undyne's long arm reached forward to smack the youth hard in the head, through his helmet, his stunts and his mouth were going to get him into real trouble one day.

"Ow," Monster Kid whined, shaking his head gently to clear the ringing in his ears.

"Any idea what type of rig I'm lookin' for Boss Lady," the young pilot asked.

"No idea Squirt, something big enough to hold a few humans, the Clown and the Punk." Undyne offered, her voice loud, the headset ear pieces did little to muffle the engines reverberation, and it was about as helpful as she could be given the circumstances.

"DOUBTLESS, THERE ARE FEW CONVEYANCES HEADED IN THAT DIRECTION THIS TIME OF DAY," Papyrus commented tightening his helmet, so he could better hear through the built in headset.

"I-I think t-that perhaps a camper or a v-van might be more likely than a pick-up," Alphys suggested.

"A-Also, I s-should mention t-that Sans' HP is h-holding at two point one six repeating."

Papyrus said nothing, but he glared daggers at the back of Alphys' head.

"Papy, c'mon let it go, we're all friends here. Heck we're the only friends we've got. 'Sides the Punk says we're a family," Undyne stated hopefully.

"I WILL, LET IT GO, FOR THE SAKE OF FAMILY. IF YOU CAN GUARANTEE I SHALL NOT EVER BE KEPT IN THE DARK AGAIN," Papyrus said folding his arms. Undyne could never understand how he managed to look like a tetchy child and Lord Death at the same time. She reached over Gerson, who was sitting between them, and fearlessly passed her hand through his halo of magic to pat his knee comfortingly.

"Papy, I already promised that, but I will again if that's what it takes to make you happy." She paused a moment before proffering.

"You know that Punk thinks of you as a big brother, buddy."

"YES, I AM AWARE," Papyrus huffed gently.

"You are the only one she thinks of that way. Sure, the King and Queen are her mum and dad, but at the end of the day who did she come to with her scraped knees, her good grades, her tadpoles and her secrets," Undyne asked.

"ME," Papyrus grinned down at his hands, and remembered holding a little girl who was more scabs than skin. One, who always seemed to be both sticky and muddy, was forever signing his name and climbing on his shoulders, or begging for a story.

"Hecks yeah, you! She's as much your little sister as Sans is your younger brother," Undyne gave him one of her big toothy grins.

"The rest of us are just a bunch of ol' aunts and uncles, or friends and acquaintances compared to you."

"EXCEPT FOR SANS," Papyrus said softly.

"That Nerd is a special case, with serious special needs. Look, I don't know how the punk feels about him yet, but I think it is pretty obvious how he feels," Undyne chuckled.

"IS IT," Papyrus asked awkwardly, slouching in his seat.

"Yes," Alphys answered.

"Yeah, " came the affirmative from MK.

"Geez, youngin' even my old eyes can see that. The only one who don't know it yet, is that slip of a girl." Gerson looked up at Papyrus, wisdom sparkling in his eyes.

"MY BROTHER IS SUCH AN IDIOT," Papyrus groaned, covering his face with his hands.

"Well, s-since it is just us here l-let me be the f-first to declare t-that I-I sh-ship it," Alphys looked over her shoulder at Papyrus, sounding both nervous and a bit giddy.

"T-though, he should at least w-wait until she graduates high school, m-maybe college."

"Well, I used to have a crush on her." MK offered trying to sound brave.

"But... after seeing how your brother dotes on her, I know I can't compete. Not that I'm scared of skelebruh or anything. Anyhow, I ship it too." Undyne scrubbed her hand over her face, her cheeks greening slightly with an undisguised blush.

"Heck, I have a confession Ego; I ship it daily, quite possibly more often. Though, I agree with Alphy, the Punk needs to grow up a bit."

"GOD HELP ME, I WISH TO SEND IT AS WELL," Papyrus uttered from behind his hands.

"THOUGH, I TOLD HIM TO CALM DOWN, THAT THE HUMANS WOULD FROWN ON HIS INTEREST. MY BABY BONES REALLY IS AN OBVIOUS IDIOT." Papyrus shifted to look at each of his friends in turn, they were all smiling on him with understanding

"What the fresh hell are you all mailing? Doncha know 'Dyna here will bite the mailman," Gerson laughed.

"SHUT UP, OL' MAN," Undyne shouted.

"Though, I will say from experience that there is no fighting the heart. That little girl will have to turn him down, with as much frost as all the ice in Snowdin, before that rascal gives up; heck even then maybe he won't," the elder turtle monster continued to snicker.

"Look, if any of you mention this shipment business again," Undyne threatened.

"I'll send ya back to Hotland."

"S-say w-who about w-what now," Alphys queried.

"Anyway, like I was saying, we're gonna have to do some serious chopper maintenance," Monster Kid offered changing the subject.

"Y-yes, complete computer s-system overhaul, especially o-once everyone has t-their trackers."

"PERHAPS, I CAN BE OF HELP WITH THE TRACKER IMPLEMENTATION," Papyrus suggested.

"Y'all scared shitless o' lil' ol', 'Dyna? How did y'all even get these jobs," Gerson wondered while he was by turns laughing and coughing.

"By God ol' man, again I say, SHUT UP," Undyne groused.

"Alright enough of this crap, Squirt any sign of them?"

"No, not a blink Boss Lady, though we should be close," the pilot grumbled, tapping the flight computer screen. Monster Kid banked a hard left bringing the craft closer to the tree line.

"Undyne, they've stopped moving," Alphys shouted, and began typing furiously on her keyboard.

"Pinpointing location… they are just beyond the treeline. MK do you see a clearing where we can take this bird down?"

"I don't think I can land her anywhere near here, sorry."

"WHAT IF THEY PLAN ON EXECUTING THEM," Papyrus' magic flared at the thought. Where his brother's magic was the cold and icy burn of the north wind, Papyrus' magic was hot and passionate like a fiery Arrabbiata sauce which he could control with laser precision; a skill that had helped tremendously when training Sans in order to raise his HP. The glow of his magic filled the cabin of the helicopter, but did nothing more than warm the air slightly around the passengers.

"Woah, skeledude don't heat up my engines," MK teased, everyone knew that Papyrus was about as dangerous, to those he called family, as a warm summer breeze. Papyrus just rolled his eyes.

"I take back everythin' I said, about this armless weirdo being a great pilot," Gerson rudely gestured at MK's back.

"You can eat it old dude, the hell I'm setting my baby down in this terrain; a vertical landing is risky anywhere, and this bird ain't got the even keel of the newer models. We've only got the one chopper, and old she may be, but she still flies true. Anyhow, I ain't taking the chance that even one of us gets dusted just 'cus you're afraid of a little walkabout." Monster Kid continued to grumble under his breath about crazy old dudes. Alphys ignored him to address the elder Bones brother.

"P-Papyrus, I d-don't think that is t-the case, I-I believe Sans and her Ladyship are perfectly safe. I am, however, getting some w-weird readings coming from Sans," Alphys began typing again grumbling under her breath.

"IS HE INJURED? ALPHYS, PLEASE I NEED TO KNOW WHAT IS GOING ON WITH MY BROTHER."

"C'mon babe, Papy's right no more nerd speak, just give it to us in plain language," Undyne was getting tired of surprises and dinner was starting to sound better and better.

"His HP is d-dropping to one then going up by half, so I have little doubt he's been injured, yet each t-time it happens his HP is d-doubling. So, one, one and a half, one, three, one, six and so on. Like he is using magic before his HP can replenish," the pretty, golden lizard monster answered.

"T-that is about as plain as I can be Undyne." The fish woman's face twisted in frustration.

"Why would that be happening, it doesn't make sense. If Clown's HP is dropping to one shouldn't he be slipping into a near coma state, just like any of us would? Are you telling me, he is slipping in and out of a coma?" Alphys shook her head, cleared her throat and turned in her seat to look at her friends behind her.

"A-as we are all now aware, S-Sans for most of his life lived with an HP of one, with possibly some d-distant d-decimal point after it; his HP often goes into infinite repeating d-decimals when it is low. While he possessed low HP, Sans was well known for two things: one, being extremely t-tired and two, overworking himself. While the latter was not as well known outside his family," here she nodded to Papyrus, "it is true none the less." Papyrus gave her a small smile and nodded back.

"I WAS SUPPOSED TO BE THE ONE WHO TOOK CARE OF HIM," Papyrus gave a solemn chuckle.

"I DO NOT KNOW WHEN OUR ROLES REVERSED. HE WAS SUCH A SMALL BEAN, SO FRAIL, I WAS SO AFRAID THAT HE WOULD NOT LIVE; I WAS… WE WERE ALONE AND DID NOT HAVE ANYONE. SO, WHEN HE WANTED TO HELP I ENCOURAGED HIM. I ALWAYS ADMONISH HIM FOR BEING LAZY, BUT I WAS… NO, I AM SO PROUD OF HIM. I NEVER QUESTIONED HOW HE DID IT."

"Tell me about, it I spent months investigating rumors of an illegal hot dog stand," Undyne scrunched her face in irritation.

"I have to admire the guy, because I never found it; I sure found Sans sleeping on duty a lot. I didn't know he had all those jobs, I might have yelled at him less."

"I-I t-think it is her, s-she may be the only reason he is alive right now… I-I have to check my notes. I h-have a, that is to say w-we found, w-well actually Sans found it and I dismissed it as a myth..." Alphys continued to mumble to herself and returned to her computer screen. Undyne was about to yell at her again when a shout came over the headset from MK.

"Boss Lady, I found a clearing, ya aren't gonna like it though."

"Squirt, tell me one thing about this crapfest of a day that I like, huh? So, where is it?" Undyne rubbed her hand over her forehead and then tugged her ponytail hard enough to make herself wince.

"Well, it's about five clicks west of our current position."

"PERMISSION TO RAPPEL DOWN DIRECTOR," Papyrus was already undoing his seatbelt and reaching for a harness.

"Denied, we don't know what the hell is going on down there, besides the dogs are on their way they can't be that far behind us. With the racket this bird is making Sans knows we're coming. Squirt, are you sure there is nothing closer?" Papyrus made a disgruntled face, but refastened his seatbelt and awaited further orders. So much was he the polar opposite of his brother, that more often than not he went against his instincts; when even now they burned within him, scorching his soul and demanding that he take action to protect what was his.

"No way Boss Lady, we are in the foothills the way it is."

"Damn it, MK this is not what I need to hear right now. Fine take us there,"Undyne commanded and the monster pilot circled the trees once more before gaining altitude and banking toward the west. They had nearly reached their destination when Alphys broke their uneasy silence.

"Undyne, we have to go back, it's Sans."
