CHAPTER ONE—Betrayal
The day started out as anything but normal. There was a monster in the house, Grunkle Stan's shorts were on fire (don't ask), and Mabel's pet pig Waddles was wondering around in the forest, lost and squealing. Mabel, of course, was out looking for him, and Dipper was set with the task of simultaneously putting out Stan's shorts and getting the monster out.
He tried fanning the fire, and it just ate more of the shorts.
"You'd better get those shorts fixed, because they're my favorite!" Grunkle Stan yelled from the other room. He was watching some romantic comedy he'd seen a thousand times, and every—every—time the butler entered the room, he'd fall flat on his face, and Stan would laugh for the next fifteen minutes. Dipper didn't even know Stan had a favorite pair of shorts.
He put the pants in the sink and pulled the handle over all the way, and went to go find that mace and get the giant fanged monster out of the bathroom. He was going to clog the toilet and the sink, and Mabel did that enough as it was.
When he got the door open—with the help of Soos—he stared at the monster in front of the mirror. It had put on all of Mabel's 'make-up' and 'perfume.' It smelled worse than Old Man McGucket on a good day. Which was never. Okay, that was once, and his son had forced him to shower—not without the awkward cat hiss—and then he tackled him and forced him into the shower. That was an experience Dipper never wanted to repeat.
After trying a fire extinguisher and the Crotch-U-Later (pun for alligator and Sasquatch and some other thing he honestly didn't ever want to think about), Dipper got the monster out of the bathroom by throwing a foul-smelling bottle of perfume out the window, the monster running after it like an excited puppy.
That was when Mabel came back, totally ignoring the monster and barreling into the house carrying her favorite animal in the world, the pig, Waddles. She exclaimed something and raised him into the air, the large pig snorting and squealing (possibly yelling that it wanted down), and squinted triumphantly at him. (Can people squint triumphantly?)
"Hey, bro-bro!" She looked around the place. "Got the bat out the belfry, I see."
He chuckled hesitantly. "Yeah, Mabel. Got those bats out." It wasn't even one bat. More like a bazillion bats stuck together into some mythical monster that likes the smell of your perfume. He swung his arm in the air like a weak yay.
Grunkle Stan wondered into the room, looking for his shorts. He glanced at Mabel. "Okay, so you found your pig. Now what?" he fished his shorts out of the sink, which had started overflowing. Turning the sink off, he drank more of the Pitt soda.
Mabel smiled that broad, somewhat freaky smile she gave when she was really excited. "Now we're gonna have a party and chug chocolate milkshakes and—"
The normally colorful room burst into grey, and a triangular demon appeared floating in the air. "You're gonna what, Shooting Star?"
Mabel's smile disappeared entirely. "Oh. I forgot about you."
Dipper frowned. "What do you want, Cipher? We've had enough of you!"
The triangle made a face like he was smiling. "Oh, Pine Tree, you have no idea what happened in the forest, do you?" A puff of smoke, and the triangle was now a human, a lemon-yellow tux draped around him, golden hair fluffed up, clean-shaven, with a midnight-black eye-patch, pants, shoes and gloves. The smile was no evident on his face, but that didn't make it any better. A kind of sinister look made it menacing.
The demon threw his hand up into the air and dropped it, a golden cane appearing out of nowhere. He seemed to enjoy the boy's confusion. Mabel looked like she was going to be sick.
Dipper turned to her, a terrified look on his face. "Mabel, what happened in the forest?"
"Oh, nothing," she lied, staring intently at Waddles. "Nothing happened."
"Oh, nothing that doesn't end with you being my servant for the next four years, Pine Tree," the demon replied casually. The boy jumped.
"The next four years?" he turned to his sister. "Mabel, you need to explain something right now! What happened in the forest?"
She looked more sheepish and uncomfortable that seemed possible. "I, uh… Came across a monster eating… eating Waddles…" this time her voice cracked. "And I wanted to save him so bad, he's one of my greatest friends, and I didn't want to loose him, Dipper don't you know what it's like to loose a good friend?"
Dipper's mouth opened a snippet, his eyes wide, his noodle-arms hanging toward the floor. "You did what?"
"I wanted to save him, Dipper! Don't you understand that?"
"So you let me become the evil triangle's servant?" Dipper yelped.
"Ah-ah-ah," the humanified triangle cooed, waving his finger in the air. "She almost sold your soul to me, you know."
Mabel grabbed his vest. "But I didn't!" She said, her face right up in his.
Dipper's face was obscured by his hat. "Yeah, Mabel. That's great."
Mabel pulled away, confused. "Dip, are you all right?"
"Oh, yeah," he answered, "as good as a guy who's been sold out by his sister to an evil demon can get, you know?"
"It's only four years, bro-bro. It's not forever." Ever the optimist.
"Yeah, but do you remember the last time Bill made a deal? He stole my body!"
Mabel smiled and punched his arm. "But this time it isn't forever!"
Dipper flinched. "So you aren't sad that you're sending your brother to live with an evil demon for four years?"
"Why would I be worried, Bro-Bro? Its four years. Nothing bad will happen!" But Dipper could tell from her voice that she regretted what had happened.
Something tore at him to make the wound worse. "Well," he said, "maybe I'll become a demon. We'll see what happens, huh, Mabel?"
The demon smiled, opened a portal, and they both stepped through, leaving Mabel with her emotions.
