*Pssst! My sister and I make a cameo in this chapter… can you find us?

Frisk and Chara are 11

"Come on come on come on!" Chara chanted impatiently from their place by the door. "I wanna go get caaaaaandy!"

"In a moment, my child," Toriel said from where she was helping Frisk add some last minute touches to their costume. "Frisk isn't ready yet." Chara pouted.

"So?" They muttered sourly. "Why can't we just leave them behind, they'll only slow us down anyways." Frisk gave their 'twin' a nasty glare, and pulled out their SOUL.

It had changed since they'd left the underground- and the resets- two years ago. It still glowed just as brightly, but it was split down the middle- one half was the familiar vibrant red, and the other was a murky burgundy.

While maintaining eye contact with Chara, Frisk reached out with one hand and delicately flicked the darker side of the SOUL.

Across the room, Chara hissed and doubled over in pain.

"Frisk!" Toriel scolded the dark haired child, who was grinning smugly. "Apologize!" Frisk sighed.

I'm very sorry, Chara, they signed, a look of utter "I'm not sorry" written all over their usually impassive features. Can you ever forgive me? Chara snorted, nursing a spot above their sternum tenderly.

"In your dreams," they muttered. Toriel narrowed her eyes, mouth open to reply, when Undyne and Papyrus came crashing down the stairs- literally.

"UNDYNE, I DON'T THINK YOU SHOULD BE WIELDING THOSE INSIDE!" Undyne laughed.

"Nonsense, punk!" she replied enthusiastically. "If Levi-heichou can do it, so can I!" Papyrus' exasperated sigh was heard even by Chara, who was almost at the other end of the house.

"YES, BUT YOU AREN'T LEVI-HEICHOU- UNDYNE PLEASE BE CAREFUL!"

The duo wandered into the kitchen, and it immediately became clear as to why Papyrus was so worried.

Undyne took her Halloween costume very seriously. So seriously, in fact, that the blades that went with her Levi costume (Shingeki no Kyojin) were actually real- very real.

And very sharp.

The walls bore numerous scars that served as evidence of this fact, Frisk noted with a wince. Undyne would be getting an earful from Toriel later on for that, they were sure of it.

Papyrus, it seemed, had gone for a traditional Halloween costume, a classic if you will:

Dracula.

Frisk had to admit, with his height and skinny frame, he pulled the whole thing off quite well.

"WHAT ARE YOU GOING AS, TINY HUMAN?" Papyrus asked. Frisk looked down at themselves and shrugged.

I'm not really sure, they confessed. I didn't have a lot of time to prepare a costume, so I kinda threw one together last minute. They gave a little twirl. What do I look like, Papyrus? The skeleton put one bony hand on his chin, evidently thinking hard.

"HMMM," he thought out loud. "YOU LOOK LIKE… SUPER-FRISK!" Frisk clapped their hands together.

Super-Frisk! They signed excitedly. That's who I'm going as for Halloween! Across the hall, Chara scoffed.

"Super-Frisk?" They repeated. "Lame." Frisk stuck their tongue out at their 'twin.'

"Chara! Frisk!" Toriel scolded the children. Neither looked particularly remorseful.

"WAIT, WHERE'S SANS?" Papyrus asked suddenly.

"right behind ya, paps."

The taller skeleton stifled a small shriek of surprise and whirled around, coming face-to-face with his… older brother? Younger brother? Nobody really knew who was the elder of the two skeleton brothers.

(Hint: it's Papyrus)

"SANS, WHAT HAVE I TOLD YOU ABOUT SNEAKING UP ON PEOPLE-" Papyrus paused. "SANS WHERE IS YOUR COSTUME?" Sans shrugged.

"i'm going as a comedic skeleton whose talents aren't appreciated by those around him." Undyne coughed into her fist.

"Sans, that sums you up in one sentence," she said.

"exactly."

"Come on, let's go!" Chara interrupted the little conversation the three of them were having. "We've been standing here forever!" Toriel sighed, and turned to Sans.

"Sans, I hate to ask, but could you-"

"take 'em out?" the skeleton finished her sentence for her, and gave her a rare grin. "sure thing tori." The former queen of monsters breathed a sigh of relief.

"Thank you Sans," she said.

Across the room, Chara, apparently tired of waiting, muttered a quiet course of "screw this" and left, door swinging shut behind them. Toriel sighed.

"that's my cue," Sans said. "c'mon, let's go-"

Toriel watched them all leave, a sudden sense of foreboding washing over her, though she couldn't fathom why.

~~wellwouldjalookiethatalinebreak~~

Things fell apart very quickly.

Undyne and Papyrus both ran off in one direction. (Well, let's be honest here, Undyne dragged Papyrus off one direction.)

Chara vanished suspiciously not five minutes after they'd left the house. (Sans had a horrible feeling the night was gonna end in mass genocide.)

And Frisk, ever the quiet child, had elected to stay by his side.

He peered down at them.

"d'ya wanna go find everyone, or get candy?" He asked bluntly. There was no point in beating around the bush with Frisk, which was one of the kid's best qualities, if he was being honest.

Frisk sighed.

We should probably find Chara before they mutilate something, they admitted. How long do we have till Papyrus and Undyne light something on fire? Sans casually checked his non-existent watch.

"oh, i'd say we have a few minutes at most," He said. "more than enough time anyways. now c'mon, let's go find a demon."

He paused.

"i know a shortcut."

Meanwhile, across the street (and this was very far, mind you, it was a very long road) by the forest, a group of teenagers materialized out of seemingly nowhere. One would assume that they'd come out of the forest, though if they'd been watching they would know that was not the case.

"Man!" one of the teenagers surveyed the streets with wide eyes. "Did the human population double when I wasn't looking, or have we been slacking on our jobs?" A raven (*referring to hair color) snickered ominously.

"Oh, we have not been slacking," he said, a note of malice hidden in his tone. "Trust me. I made sure of that." the only blond knit his eyebrows.

"You sure Jeff?" He asked. "If anything, it looks like you've taken a break."

Nobody batted an eye as the raven, dubbed "Jeff" swung at the blond boy with a knife, rusted with blood, and nobody seemed to care when it passed through the blond.

"Jeff" grinded his teeth together.

"Stop fucking around, BEN!" He growled. The green-clad teen stared at him, eyes glinting crimson in the light.

"I'm not doing anything," he drawled. "I just lost control of my form temporarily." Angered, Jeff made to swing at him with the knife again, only to be stopped by a figure in a blue mask.

"Calm it Jeff," he said quietly. "It won't do us any good to get arrested this early on in the night." Any passerby, if they hadn't called the cops already, would've expected this Jeff to try to stab this figure in the blue mask as well.

Much to their nonexistent surpirse, Jeff simply stowed his knife away in his pocket, grumbling all the while.

"C-C'mon, l-l-lets get *tic* c-candy!" a brunette to the left of the group said, ticcing spasticly the entire time. Out of everyone in the group, next to Jeff and the figure in the blue mask, he had the place for third or fourth "Most Unnerving." He wore a smiling facemask that hid the bottom half of his face from the world, and a pair of bright orange goggles that currently rested over his hair, though it was balantedly clear that when worn properly, they would hide his amberish eyes as well.

Then there were the hatchets at his sides, one with an orange gleaming handle, the other rusted with age. Both hatchets were coated with a suspiciously dark red liquid.

"Relax, Toby," the one in the blue mask said. He seemed to be the leader of the little group. "You'll get your candy eventually." the blond, BEN, if you remember correctly, floated up onto his back.

"So let's go then," he said. "Why are we waiting around?" The masked one sighed.

"You know why…"

There was a moment of silence, then Jeff drew in a sharp intake of breath.

"You sure that's a good idea, EJ?" he asked. "I mean, I'm all for murder, 'don't think I need to prove that, but he nearly took out the entire neighborhood last time!" The masked one, dubbed "EJ" hummed thoughtfully.

"LJ'll be fine," he said dismissively. "Slender and I went to… special measures to ensure no genocide took place." The twitchy not from earlier frowned.

"Wh-what kind of *tic* m-m-measures measures?" He asked.

"They took away my chemistry set," a new voice interrupted moodily. Jeff rolled his eyes, not bothering to look away.

"Only you could make poisonous candy with a kid's chemistry set," he muttered. The newcomer, (presumably LJ) pouted.

"At least I know how to use a chemistry set," he muttered sourly.

EJ, seeming to sense and incoming fight, quickly redirected their attention.

"Ok, everyone remember the rules?" He asked the group, but he was looking at LJ. The clown pouted again.

"No mass genocide," he muttered. EJ nodded.

"Killing's allowed though, obviously," he added. Jeff snorted.

"We'd have an uprising on our hands if it wasn't," he said, before running off into the night, the others close behind him.

Trick or treat! Frisk signed excitedly, holding up their pumpkin. The brunette who had answered the door smiled slightly.

"I'll be the first at admit I don't know a lick of sign language beyond the alphabet," she admitted. "But even I know what that means." She held out a cauldron of candy. "Take your pick?" Frisk gave her a toothy grin, and picked out a Coffee Crisp. The girl nodded approvingly.

"Good choice," she said. "My personal favourite." Frisk giggled, just as a blonde came running up, and grabbed a handful of candy, then ran away, giggling the entire time. The brunette sighed.

"That'll be my sister," she drawled. "If you'll excuse me…" putting the cauldron to the side and pulling out a sign that read "Take one and ONLY one, or I will smite thee with mine magic powers!" The girl jumped down off the porch and ran off into the night, yelling something that sounded suspiciously like: "BLONDWAD! GET BACK HERE YOU PLONKER!"

Sans and Frisk watched her go, identical looks of bemusement playing on their features.

"she's got character, i'll give her that," Sans broke the silence. "c'mon kid, plenty more houses to hit." Frisk nodded happily and jumped down the stairs.

The skeleton and human walked down the road, then up a driveway.

Trick or treat! Frisk signed.

Sans watched the neighborhood absentmindedly as Frisk did their trick-or-treating. He liked Halloween, he decided, even if some of the costumes gave him reason to bleach his non-existent eyes. The atmosphere lifted his mood, and the cool night air was refreshing.

It was nice.

Less nice, perhaps, when a flying wad of toilet paper lodged itself in his eye (he didn't even want to know) but he could appreciate it all the same.

~~~backwithourprettylittlepsychos~~~

"Go to sleep!" Jeff hissed as he dragged the serrated edge of his knife along the jugular of the man who's been foolish enough to question where he'd gotten his makeup done. (It wasn't makeup, you fool, he was the real effing deal.)

"Again?" BEN asked from where he was floating behind him. "This is your third kill in the last half hour, Jeff. Calm the fuck down." The smiling killer sighed.

"I can't expect you to understand the joys of bloodlust," he said melodramatically. "After all, you're usually playing the part of the coward behind the screen, eh?" BEN bristled.

"I know what bloodlust is!" He said hotly. "And I can appreciate the thrill of murder just as much as anyone else, thank you very much!" Jeff opened his mouth to reply, when two girls came tearing down the street.

"GET BACK HERE YOU LITTLE PIECE OF SHIT!" The one in the back screamed. The blonde child she was chasing laughed manaically and poured on more speed.

"I SWEAR TO GOD, IF YOU DO ANYTHING THAT HARMS MY YAOI, I WILL GUT YOU LIKE A FISH AND DANCE ON YOUR ENTRAILS!"

Jeff whistled appreciatingly.

"It's always nice to see someone with a natural bloodlust," he said. BEN hummed in agreement.

"Yes, it is, isn't it?" He agreed. "Very refreshing."

The two watched the girls run around for a bit (from what they managed to deduce from in between threats of quartering and other medieval torturing devices, the blond had stolen some candy and the brunette's phone) then decided to get a move on, before they were noticed and had to kill the girl. (Because really, that would just be wasted potential.)

~~~~letimeskip~~~~

"Got any Reese's?" Jeff asked when they met up at the mansion later that night. Toby nodded.

"Mhmm," he said as he popped one in his mouth. "And now-now I *tic* d-don't." Jeff scowled.

"You motherfucker…"

~~~anothertimeskipbecausetheauthoristiredandwantstosleeobutpreallyneedstogetthisdone~~~

"we're back!" Sans announced as he and Frisk walked through the door. Toriel came out to greet them.

"Did you have fun?" She asked. Frisk nodded and held up their pumpkin.

I got a lot of candy! They signed. Toriel laughed.

"I can see that my child," she said, then turned to Sans. "Sans, again, thank you so much for…" her voice trailed off. "Sans, where's your brother?" Sans shrugged.

"dunno," the skeleton said. "we kinda got separated. we looked for him, of course," he added upon seeing the Mom Glare Toriel was wearing. "but gave up after half an hour." Toriel chewed her lip.

"That's not exactly reassuring," she muttered. Sans shrugged

"relax, tori, i'm sure he's fine- he's with undyne." Toriel's eyes widened.

"You left Papyrus and Undyne alone? Together?" The pinpricks of light vanished from Sans' eyes as he realized what he'd potentially doomed the world to.

"oh shit," he muttered. "c'mon, we gotta find them- if we hurry maybe we can postpone the apocalypse to next tuesday."

*In case it wasn't clear, Toriel had to stay to hand out the candy

So BAM, first special done! How'd I do, didja guys like it? I know I had fun writing it even though I kind of left it to the last minute *cough*at the time I'm writing this it's 11:27 pm on the 30th of October*cough*

Also, what are you guys going as for Halloween? I'ma gonna be a mad scientist. :) (I've even got a real lab coat for the occasion- and I totally forget the name of the university where I got it.)

Anyways, have fun on Halloween, and if you don't do Halloween have fun doing whatever the hell you're doing!

Au revoir, little biscuits!

PS- how many of you found my sister and me? It's kinda obvious, I'll admit, but shaddup, I had fun writing it.
