anyway more specifically, this takes place sometime after Sock Opera in gravity falls and after season 17 of South Park.

We all know the treatment of Kenny's Special Position varies from fic to fic as it does episode to episode, so I'll just tell you up front: yes, he dies, no, no one remembers, no, he doesn't come back via his mom. he just wakes up in bed. it is a ~mystery~. now you know everything you need to. huzzah!


Kenny McCormick leaned his head against the window of the bus. The shake of the glass would have been annoying if the thick material of his hood wasn't cushioning the jarring vibration as the bus ran over unpaved backwoods roads, so he counted himself lucky to have it. He ran a hand through his sister's hair absently- she had her head in his lap, sitting beside him and totally passed out. The bus ride had taken over fourteen hours, and even though they were nearly there he wasn't in a rush to wake her, or Stan and Kyle, who were leaning against eachother in a way he suspected they would assure him was totally platonic later. Even Cartman and Butters were asleep in the seats across from him- though he wasn't sure how Butters could sleep with Cartman practically suffocating him by using him as a pillow.

He was actually fairly certain he was the only one on the bus other than the driver who was awake. He didn't like to sleep in unsafe places like buses or tents- especially not with his sister so near. He would much rather strengthen his odds of surviving the night with a roof over his head, and preferably a tazer jammed between the mattresses.

The trees passed him lazily behind the glass pane window, the sky growing brighter and pinker with the the sunrise. To be honest, he'd been glad when Stan's mother had suggested the trip. Summer was never a good season for his family- they were always on a budget, and without the free lunches the school provided and with the ever looming electricity bills to worry about, his parents were almost never in a good mood. No one had argued when he'd asked to bring his sister along with them to Stan's great uncle's house in Oregon- his friends had been annoyed, but the adults had just nodded knowingly.

Kenny hadn't actually known Stan had had a great uncle, but Stan had groaned and sighed when they he had asked and told him that he did, in fact, have an aging great uncle Stan- whom he was named for. Someone they had all expected to die before he had gotten old enough to get their names confused at family reunions. This had not been the case.

Stan said he was Randy's mother's brother, and a real cheapskate. Apparently he was also taking care of some other relatives children this summer and when their parents had offered to send him a monthly stipend to take care of them, too, he'd been more than happy to.

Kenny wasn't really concerned. South Park was dangerous, and he rarely regretted getting a chance to stay away from it and its shenanigans for a little while.

The bus slowed to stop beside a sign indicating they were in Gravity Falls, Oregon.

He nudged Karen awake and she slid out of the way sleepily so he could stand on the seats and pulls down their bags. Small bags- a few changes of clothes, basic toiletries, Karen's doll. They didn't have much. Not like Cartman, who had managed to rope Butters into carrying all three of his duffel bags in addition to Butter's own duffel and backpack. He gave Karen her doll, and she crushed it against her chest with one hand, taking his in the other as they stepped off the bus into the dim pink Oregon dawn.

There was an old man waiting for them, along with two brown haired children about his age, but obviously a bit older, that looked entirely unhappy to be there this early in the morning. The old man was asleep.

He must have been Stan's Grunkle Stan.

The girl jumped up immediately, her sleepy demeanor totally lost as she actually stood on the bench and ripped a knitted sweater from her backpack, "You're here! I made you all sweaters! This is gonna be the best summer ever!"

The boy groaned beside her, looking exhausted, "Mabel..." he sighed.

"Shhh, Dipper, be nice. They're from Colorado."

"What does that have to do with anything?!"

She looked like she had a response ready, but Kyle cut her off, "Hey! I guess you're Mabel, then? And that's um- Stan's Grunkle Stan?"

Mabel snorted, "We have two Stans. This is gonna be fun."

The old man hadn't woken up yet, and Kenny wasn't sure if he should do something about that. Before he could decide, Dipper nudged him and he jumped up, startled.

"Huh? Wha? Oh! You're here. Great. Okay, well, we're really gonna have to squeeze to get you all in the Mystery Cart, but what is it you keep sayin', Mabel? Believe in yourself and you can do anything. Yeah. Sure. Alright, let's go."

Kenny picked his bag back up from the ground, following quietly while Mabel tugged a light blue sweater that looked to be about two sizes too big over Butter's head.


Stan and Kyle had taken the spare bedroom downstairs, and after some goading, had agreed to let Karen stay in their room. He would much rather have her in a room that wasn't his- bad things tended to happen to him when he wasn't paying attention, things he would like to distance her from. Which left him in the basement with Cartman and Butters- which was honestly how he preferred it. Cartman was obnoxious and had been responsible for his injury on more than one occasion, but Kenny was probably the only one other than Butters who could tolerate him in large doses, and he had always liked Butters' company.

Basements were also, usually, safer.

They'd all been ready for breakfast, tiny ten-year-old tummies rumbling when Mabel had suggested pancakes. Kenny was particularly excited about pancakes- actual pancakes, made from real batter with real butter and syrup that he could eat on an actual plate that he wasn't supposed to throw away afterward.

Mabel, of course, refused to let them eat until she'd stuffed them each into a sweater. Stan's was a darker blue than Butters', Kyle's green, Cartman's red, Karen's pink (and distressingly large on her), and his was orange. She'd tried to convince him to take off his hoodie and replace it with the sweater ("How are you going to eat these deliiiiicious pancakes I'm making with your face covered like that, huh?") but he'd just quietly tugged it on over his hoodie. It wasn't that he disliked it- to the contrary, he loved new clothes, especially warm ones, and it was his favourite colour, and it was soft- but he really wasn't comfortable pulling his hood off around these strangers just yet.

"Holy fuck, these are good," Cartman said, face oozing syrup and stuffed full of pancake. Mabel gasped dramatically, flinging a pancake directly into the ceiling from her stepstool in front of the stove.

"Hey! None of that! Your parents told me to break you kids of your weird swearing habit. Keep it PG," Grunkle Stan said, blatantly annoyed but not nearly as alarmed as Mabel had been, before he returned to reading his paper.

Kenny may have taken more than his share of syrup, but he didn't really feel bad about this.


"Kenny, dude, go back to your room, it's like fucking ten O'clock and none of us got any sleep last night."

Kenny frowned and turned toward him, "Jesus, sorry dude, let me tuck my fucking sister in, okay?"

Stan groaned from his bed and covered his head with his pillow. Asshole. He turned back to Karen who was sitting up and looking at him.

He bopped her on the head lightly and she lost the worried look in her eyes with a giggle, sinking back down as he tugged the covers over her. She pulled her doll tighter against her on the cot and smiled, before whispering, "Thanks, Kenny," too quietly for Stan or Kyle to hear from their respective corners.

He just smiled back at her before ruffling her hair and standing to leave.


Kenny leaned out of his "Mysterious Child Who Never Reveals His Face!" display to take a peek at Dipper, who was standing somewhat less than enthusiastically on a stage wearing wolf ears and making pathetic fake howling noises. The crowd took a few pictures and moved on past him- probably to Stan's begrudging fake medium act in the back.

"Psst," he said, and Dipper looked up at him, startled, "This is really fucking boring."

"I, uh- I actually didn't realize you could talk," Dipper said awkwardly, rubbing the back of his head. Kenny shrugged and Dipper dropped his arm, "Yeah, it's... pretty, uh... friggin boring. Yeah."

Kenny snorted, and Dipper's face lit up red.

"Hey! Shut up," he said, crossing his arms, "You can just talk to yourself then, jerk."

He raised his arms and shook his head, "No, come on, it's whatever," Kenny said apologetically, "What do you usually do for fun around here, anyway?"

"Fun?" Dipper repeated, looking up in thought, "Uh, I guess we usually just investigate the woods for weird mystery stuff, or go into town."

"You wanna ditch and go to town?"

Dipper looked at him, "Grunkle Stan'll be mad."

Kenny just smiled, and after a moment, Dipper returned it and hopped off the stage before helping Kenny over the tiny fence.


"What's that?" It was a pretty simple question, but Dipper responded pretty violently, shoving the weird looking horn he was holding back under his vest a little too quickly and staring at him with alarmed, wild eyes.

"What? What's what? Haha, nothing," He giggled, somewhat hysterically, and Kenny took a step back. Odd behavior made him nervous. Odd behavior made his hand itch to grab the tazer he'd shoved down the front of his pants, but he also didn't really think these people would take very kindly to his tazer and he really, really didn't want to lose it, so he refrained.

"Th- the thing. The thing you were literally just holding."

"It's- It's, um..." Dipper's eyes darted around the room nervously, and Kenny decided now was probably a good time to leave the kitchen, even if he had been hungry- weird behavior was never a good sign for him and he was quite determined to survive the summer.

That was when a large, black pegasus with a glowing red horn came smashing through the window, whinnying like a screaming child and beating fire from its massive wings.

Kenny immediately dove under the table, the closest form of protection he could locate (he had, of course, scanned the room upon entering it, just in case something like this happened, because something like this always happened) and grabbed Dipper by the back of his vest and yanked him down and under the table with him.

The shrieking animal shot some kind of blast from its horn where Dipper had just been standing, blowing a cabinet to dust.

Kenny rolled away, behind it, towards the wall it had just made a sizeable hole in and pulled himself over it, ignoring the cuts and scrapes the jagged material was leaving behind. He was already running, looking back, waiting for the creature to reemerge- before he noticed that Dipper wasn't following him. He swore, loudly, and ran back, peaking over the hole. Dipper was still leaning against the table, and the unicorn thing was pacing around the kitchen, sniffing cabinets idly, but menacingly. Dipper looked like he was going to have a panic attack, huffing and puffing.

"Hey, asshole!" Kenny hissed at him, a little louder than he meant to. The unicorn looked at him sharply. "I'm gonna let it chase me, then you run, okay?"

"What?!" Dipper cried, hardly an acknowledgement, but the beast had made up its mind and beat its massive wings against the ground, even as its horn started glowing again. Kenny ducked, and the red blast of hot energy missed him. He was lucky that he managed to roll away from the wall before the horse crashed through it again, and he started running around the corner of the house. Stay out of line of sight- head for the woods where there was more tree cover-

The first shot took out his left arm. The damage was familiar, and didn't take long to assess- he'd lost everything below the shoulder, and there was still quite a bit of splintered bone attached. He had been lucky, though- the blast had been hot and had, for the most point, cauterized the wound. It had left some major burns down his side and up his shoulder, but at least he was less likely to bleed to death immediately. It hurt, but it would hurt a lot more if he stopped running. So, he choked back a sob and stumbled forward, moving serpentine towards the treeline.

So much for surviving the summer.

He actually ran into the first tree he came to, his center of gravity totally ruined by the missing limb- not to mention the pain and blood loss was seriously disorienting. It took him a few extra seconds to slide himself off of it and keep going, and those few seconds were what cost him. The blast actually hit a tree next to him, not him specifically, but while the blast may have missed him, the tree itself did not.

He fell forward as it hit him, and he noted with dissatisfaction that it had likely snapped his spine- or at least ruptured something serious in that general area, but there was too much blinding, searing, white-hot pain to identify too specifically. He was pinned beneath it, unable to move his remaining arm. Probably the spine, then.

Through the roar of blood in his ears and the sound of the animals freakish nickering, he heard Dipper's voice chanting something in an unfamiliar language nearby- far too closee. He wanted to yell at him for being a fucking idiot, but there was a bright light and a popping noise, and the sound of much smaller hoofbeats as a goat trotted up past him and tilted its head, looking at him curiously.

He whined in pain and confusion and moved his head weakly. Stupid. Did the horse thing turn into a goat? What the hell just happened?

He didn't have very long to think about it, because it only took a few more seconds for everything to go dark.
