Dipper and Mabel vs. the Multiverse

Mabel's legs carried her as fast as they possibly could through the forest. She wasn't thinking about how hard they were working. She only cared that they would take her as far away as possible from the awful thing which made her feel bad. "Summer ends." Dipper had said.

"I don't want it to end. It's not fair. It's not fair. IT'S NOT FAIR!" Mabel thought to herself, as she continued to run, sobbing along the way. Her heart weighed in her chest, and her guts weighed in her stomach, but still, she kept running. She just wanted it all to be good, to all be okay, but she couldn't get that.

After Candy and Grenda said that they wouldn't attend her birthday party, she tried to stay hopeful in spite of that double-betrayal, that one-two punch to her feels. After Wendy had told her about how much high school was gonna suck, she felt even more betrayed. She had no idea that even those awesome Disney movies were also lying to her the whole time. She thought that at least she had Dipper, and even Grunkle Stan agreed; he reassured her that she'd have him forever.

But then Grunkle Ford took that from her, too. And she just couldn't handle it.

Because without Dipper, she had nothing left.

So she ran. She kept running, until she got tired. "There's a tree, over there. Looks comfy," she thought to herself, "Now it's gonnna be my sad-tree." Then, she sat down. When the adrenaline wore off and her pounding heart started to slow down, Mabel was left only with bad thoughts, which intermittently popped up in her head, reminding her of how much her life sucked. Because she wanted to have at least one thing to make her happy, she took off her backpack, hoping to find something that would do the trick.

She reached into the backpack, and said aloud, "Only party chocolate can cheer me up now." But when she reached in, she soon found that the contents were pretty unfamiliar. She pulled our a notebook, and looked at it. Once she realized what it was, she said, "Nerd books?" and when she reached again, and felt pens inside, she pulled them out, and said "Chewed up pens? Ugh, wrong backpack." She plopped-down the backpack out of frustration, pulled her sweater over her head, and said, "Not fair. I just wish summer could last forever." Though there was nobody else to hear this, she felt somewhat calm at the sound of her own voice, solidifying the otherwise messy, mish-mash that usually clouded her brain.

But then, a voice answered: "That might be possible!" The voice was sorta nervous-sounding.

That voice-whatever it was-was an unwelcome intrusion into Mabel's mindspace. She had just gotten accustomed to the depressing-but-calm downer-aura over her thoughts, and then that too got interrupted. It stirred her.

Mabel said, "Sweatertown is not accepting incoming calls right now."

The next thing she heard was, "M-M-M-Mabel, it's me."

Mabel replied, "What? Who said that? " Then, she saw someone familiar to her: the fat time-traveler, Blendin Blandin; he was adjusting his watch, and his suit was going all wacky with pictures of places, like it did before.

"I-I-I can help," said Blendin.

"The time travel guy? What are you doing here?"

"You said you don't want summer to end, right? D-did-did I hear that right?"

"There's no way..." thought Mabel to herself. She began to feel a little hopeful, if still a little confused. She then said, "Yeah... why are you asking?"

Blendin explained: "Look, maybe it's against the rules, but you once did a favor for me, so I thought I could help you out. It's called a time bubble, and it prevents time from going forward. Summer in Gravity Falls can last as long as you want it to!"

Mabel became exited. Curious, she asked, "R-Really? But how does it work?"

"I just need you to get a little gizmo for me from your uncle." said Blendin, activating his watch to show her a holograph of a little globe on some tubes and stuff.

"It's something small. He won't even know it's missing." he continued.

"Huh. Maybe Dipper has something like that in his nerd-bag." said Mabel, feeling clueless as to what she was even supposed to be looking for. Then, her fingers felt a glass thing, and some metal and plastic and rubber around it. She pulled it out, saying, "Huh. That's... odd. This it?"

Blendin looked excited. "Yes, that's it! Just hand it over and I'll do my thing," he said. "Unless you're ready to leave Gravity Falls."

"Just a little more summer." said Mabel. She wanted summer to last forever. She wanted to be with Dipper forever. She wanted to be with Wendy, and Soos, and Grunkle Stan-forever. They made her feel so happy; the thought of staying with them as long as she wanted filled her with such a wonderful hope. She gave Blendin the weird thing-a-majiggy.

Blendin took it. Then, he dropped it, saying, "Oops."

The glass science-thingy fell out of Blendin's hands, towards the ground.

A green, swirly circle appeared on the spot beneath the weird gizmo.

A pale, skinny hand shot up from the swirly green circle. It grabbed the thing.

Mabel didn't know what the thing was, or what it did, so when Blendin dropped it, she actually wasn't as surprised as Blendin was during the instant the green swirly blob appeared on the ground. A man in a white coat with crazy hair, holding a gun flew up out of the blob and kicked Blendin to the ground; then, the chartruse hole in the ground disappeared. Mabel was immediately shocked. She heard Blendin stammer a little, and the old man put the magical space snowglobe and his gun into his white labcoat.

"YOU!" said Blendin, sounding super-vicious-his face looking as shocked as it did angry.

The old man pulled out another weird-looking gun and said "That's right, Bill, ME!" Then, he shot Blendin sevral timez. The shots weren't loud-instead of "bang", they were more like "pew-pew", and they were bright, so Mabel figured it was a laser-gun. Mabel couldn't keep track of what was happening, really. She had no idea how much time had even passed since she handed over the science-thingy. She had been sad before all of this, but now, she was mortified.

Mabel watched as Blendin stumbled to the ground, falling flat onto his back once more. She wasn't even thinking at this point, since she had long since fallen out of Sweater-Town, and into the strange realm of Science-berg. She let out a little "Um..." as she saw the man start walking towards her. Then, the strange man bent down and grabbed Mabel by the shoulders.

He started to shout: "Hey, h-hey you!" Mabel responded only by looking at his face: a sickly, wrinkled old man-face with crazy pastel-blue hair.

"Do you have ANY idea what the fuck you were DOING?"

Mabel didn't know how to answer that question, but she did instinctively eke out a "No!"

"That was BILL CIPHER! He was trying to-oo use that-that thing to bring the freaking NIGHTMARE REALM into your dimension! Didn't Stanford *urrp* tell you about it?"

Several thoughts raced through Mabel's head at once. She knew who Bill Cipher was, of course, but she had no idea what the Nightmare Realm was, and she definitely wasn't told about that weird portal-thingy by Stanford.

"Look-I get it. I sell shit like this to intergalactic, interdimensional warlords every no-ow and then. Who knows how many dimensions got-got fucked over because I handed over something I knew nothing *urrrp* about?"

Mabel tried to stare past him, or close her eyes, or look away, anything to get away from the nasty smell of hobo coming from his face. She ended up squirming a little. She remembered that she was covered in Blendin-bits.

"But I mean, COME ON! Eternal summer? I mean, what the fuck you were thinking there? You-you really think that guy was gonna give you eternal summer? A-a-aand why the hell would you even WANT something like that? You do realize there's a planet in our solar system with eternal su-uumer, right? It's called Venus, and if we all lived there, everyone's faces would melt off. Is that what you want?"

"NO!" replied Mabel, finally finding some courage from the depths of nowhere. "THAT'S NOT WHAT I WANTED! I just wanted to have my friends around, and they were all leaving me behind! First Candy and Grenda, and then Grunkle Stan... And then Grunkle Ford took Dipper away from me, too! IT'S NOT FAIR, OKAY?"

"Whoa there, sound-sounds like you have some family issues huh, Sweater-Morty?

"What did you call me?" replied a perplexed Mabel.

"Well, you-u're related to Stanford Pines, right? He takes you on adventures and stuff, r-right?"

Mabel felt unusual, as if a weight was being lifted off of her shoulders, by this stranger who had just killed a guy she sorta knew, and was covered in his blood. "What? Well, sort of... Actually, he wanted my brother Dipper to go on adventures. Just Dipper, though..."

"And why's that?" replied the strange science-man.

"Well, he thinks Dipper's a genius, and he thinks I'm too stupid... Like my Grunkle Stan, I guess..."

"W-wow... That, *urp* that sounds pretty harsh..." said the guy, beginning to look concerned, "Want me to tell you a secret?"

"W-what kind of secret?" replied a curious Mabel.

"A science-secret!" he said, but Mabel remained skeptical.

"You're supposed to go-o on adventures with your brother. You two, there's *urrrp* a scientific reason you-u two, specifically, are supposed to go together!"

"Really?" said Mabel, her face now lit up. "What's that?"

"I-it's way too complicated for me to explain to you right now, and I gotta hand this thing over to Stanford. But, let's just say... You two have special brainwaves, and your 'grunkles' probably do too."

"Twin-brainwaves!?" replied an awed Mabel.

"Uh, yeah, some *urrrrp* something like that." said the portal-scientist, "Hey, you wanna go home, right Sweater-Morty?"

"Yeah... But wait, who are you? And how do you know Grunkle Ford?" said Mabel.

The man didn't listen to her. Instead, he took his gun and shot another green circle. The next thing Mabel knew, she was flung face-first into the portal. Just as her mind began to acknowledge the feeling of the thick, swirly, green fluid pressing against her, she was greeted with the sight of a familiar stretch of woods. As she landed, she stumbled a little bit. She turned to the side, and confirmed that she was indeed in front of the Mystery Shack. Then, she sat down, spread her arms out, and just lay on the ground.
