HI, this is a reverse pines story as you can probably tell. I tried to write it like how I pictured an actual episode going. The idea for reverse pines isn't mine, and design with original idea all goes to original artists and creators. I would credit them, but there is so many of them I don't know who thought of it first. And I don't own gravity falls…as far as you know. MWAHAHAHA!

Oh, and note, in this one there is a human bill cipher that is the twins age along with the regular one who's name is will. The two of them used to be one person, but then they split off when the human one got bored of being evil. It's a long story, I might write a fic on it to explain. If I do I'll reference it in this story later. He won't be in much of this story though, but he's really important to this one so I couldn't take him out. And Stan's brother is in this story! Yay!

"You'll never get away."

"No," Mabel whimpered.

"You should have listened to me when you had the chance."

"P-please," She sniffled, wiping her eyes.

"Prepare to die!"

"AHH!" She shrieked, as the red liquid fell all over herself. Then she lay there, dead.

"…"

The sound of clapping erupted in the room.

"Bravo, bravo! That's my girl, good job!" Mabel's eyes flickered open and she grinned, showing off her braces to the crowd while Dipper pulled the fake knife out of her shoulder and threw it to the side. Her brother helped her wipe off the ketchup off of her plain shirt and helped her get up. The two of them held each other's hands and bowed to their little crowd of friends. Grunkle Stan whistled, while Grunkle Stanley (the author) clapped politely in his seat. Wendy and Soos cheered for the whole performance, while Will (Read authors note) clapped happily for the blood effect at the end.

"Wow guys, good job," Wendy congratulated them. "You two really have a thing for performances." Mabel shone like a star with happiness, but Dipper just shrugged carelessly as he pulled the fake vampire teeth out of his mouth.

"Yeah, it's fun to do once in a while, but I think this is the last performance the pine twins are going to do this summer."

"Boo!" that was Will.

"Aw come on bro," Soos complained. "You guys are great actors! And the twin turning on twin at the end was a nice touch."

"Heck, it had me at the edge of my seat the whole time," Grunkle Stan revealed. "You two should do performances for the shack. We'd make a fortune!"

"Don't you mean YOU would make a fortune Stan," Stanley confronted.

"Hey, I'd buy them ice-cream for their hard work!" He shrugged. Everyone in the shack's living room rolled their eyes. Except for Soos, who grinned and nodded, very convinced. But both Mabel and Dipper shook their heads.

"Sorry my wonderful fans," Mabel apologized dramatically. "But, tragically, this is the end of our tour. We hope to see you all again…in the afterlife." With a laugh she ended the dramatics and explained, "I wanted to do another performance that actually had a good ending, since my puppet show one ended badly." All of them glared at Will. "But this was more fun."

"Well, too bad," Stanley sighed, getting up from his seat on the ground. "I thought you two were pretty good." Brushing off his worn out jeans he huffed and said, "Whelp. I guess I should be going to see how old Mcucket is doing." Dipper, who had become a bit of an author fan boy since he got there, instantly jumped up at his words.

"Really? What are you going to do? Can I come?" He happily begged. Stanley laughed while Stan sighed and mumbled something about trying to keep his grandkids safe from all the dangerous of the town. Mabel laughed and hugged him for support.

"Maybe next time Dipper. I think you have to work at the shack today, don't you?" At his words Dippers happy mood fell, reminding him of his promise to grunkle Stan to help out at the shop for the rest of the day.

"Hey, is that any way to react to being given the amazing opportunity to work with your grunkle Stan?" there were a few 'meh's' and 'probably's'. "I hate you all. Anyway, back to work everyone! Look alive!" There was a lot of grumbling as everyone got up from where they were sitting and headed over to the advertising area to get to work. Mable pulled off the red blanket that she had used as a cape and hurried to catch up to Will.

"I think that play went really well," Mabel boasted to Will as they went into the shacks gift shop.

"I liked the twins turning evil part," He commented, a snicker slipping on his face. "Heh. Just imagine the pine twins running evil havoc over gravity falls. That would be hilarious!" Mabel laughed and punched him in the arm, making him wince and fall a little bit. He was having such a hard time with his new body, every movement made him stumble and fall.

"WHAAAT? Yeah right. Me and my brother are the best! Sure dipper had those little moments in the past where we thought he might have bene losing his mind and getting all squirrely in the head."

"I can hear you." The both ignored him.

"But we're both angels now! And who would want such amazing people like us to ever turn evil?"

"I can think of a few people," Will suggested, his mind immediately turning to his counterpart, Bill Cipher. Mable stuck out her tongue and made a 'pff'ing sound with her lips.

"Come on! So Dipper fell of the wagon once. Or twice. Maybe will again."

"I am standing right here."

"But he always comes back! Do you really see people as sweet and innocent as us ever turning to the dark side?" She questioned. Wendy took her seat at the counter as she listened in on their conversation.

"Yeah man. I can just not picture their innocent little faces," Mabel smiled at her sweetly. "With the forces of evil." Soos, deciding to join the conversation, went over to Dipper and Mabel and put his arms around both of their shoulders.

"These two have the faces the artists used to mold angels." Mable blushed sweetly while Dipper laughed and told him to shut up, pushing his arm off of him. Will, on the other hand, looked at the group unconvinced.

"I'm not convinced. I used to work with a dream demon, I can picture any of you doing any evil thing." Narrowing his eyes with an evil grin he whispered to Mabel, "Even turning waddles to bacon." She screamed and ran over to her beloved pig and held onto him like his life depended on it. The rest of the group laughed at the idea of Mabel ever hurting the pig that she had worked so hard to get. Will grinned again, with a gleam in his eye that the rest of them hated. He always knew something that the rest of them didn't.

Wendy always shivered when he did that. "Dude, don't do that, it freaks me out. Seriously though, there is no way that I would ever be afraid of anyone who looked like these awesome kids. Heck, the day that I do, I'd start wearing old lady glasses and wear suits to work." Everyone laughed at the idea of Wendy going anywhere without her regular plaid style. Will on the other hand, his yellow eyes started to glow and his smile grew wider than humanly possible.

"oooh, do I smell a deal?"

"What? uh, actually,"

"I'm in! If I can show you an evil Dipper and Mabel that you are afraid of by the end of the week, you've got to come into work one day and wear a suit for a whole 24 hours!" the other's in the group glanced at each other nervously. Though Will didn't have as much power as Bill did, he could still do a lot of damage. And considering what Bill had done when he possessed Dipper, he certainly did NOT want to go through something like that again.

"Uh, you're not going to, like, do something bad to me and Mable are you?" Will had to think about it, but then waved off the idea.

"Yeesh kid, relax!"

"I'm the same age as you." He ignored that.

"I'm not gonna do anything to you! Then I wouldn't be able to see the looks on your faces!" Sometimes they wondered why they dealt with him. Oh yeah, because he gave Mabel all the sparkles she could ever want. Wendy, once that was out of the way, relaxed and leaned forward across the counter.

"Alright. I'll make you a deal." Will grinned and reached out to shake her hand, but Wendy stopped him. "BUT, if I win, you have to stop wearing that top-hat you love and start wearing a regular kid hat." With a yelp Will reached up and grabbed his hat so it wouldn't' disappear. Wendy glared at it like it was the bane of her existence. "That thing is driving me crazy! Kids don't dress like that!"

"Hey, and along with that, you should wear a t-shirt and shorts," Mabel added, poking his yellow suit. Will glared at her for joining in his torture.

"Fine, but then you have to wear an outfit of MY choosing for the day if I win!" Everyone turned to Mabel to see what she would say.

She thought about it for a moment. "Hm…what do you think Waddles?" She turned to her favourite pig. The pig looked up at her and oinked. "I'll take that as a yes." Turning she held out her hand to Will. "You got yourself a deal!"

The boy grinned. Crossing one hand over to shake hers, and the other to shake Wendy's, while Dipper watched with worry and his hands glowed, sealing the deal.

"This is going to be bad, isn't it?" He asked, turning to Soos.

"Dude, when is it ever good?"

…

After a couples of days, the group had all but forgotten the bet. Dipper and Mabel were up in their room, Dipper reading the adventures of Sherlock Holmes while Mabel was enjoying painting funny faces onto Waddles's back. She giggled as she painted a really bad portrait of Dipper in red paint. "Wow, you look so red Dipper." Dipper glanced over his book at her painting, made a face and turned back. Mabel huffed and put her hands on her hips. "Don't you want to try? It's fun!"

"I'm reading." Annoyed, his sister pulled herself onto the bed and started jumping up and down on it.

"Come on! Let's play a game! Let's play a game!" He grunted, trying to keep his balance while reading.

"Go ask Soos or Wendy to play with you, I'm reading!" He reached back and threw a spare pillow at her, sending her sprawling to the ground.

"Oof! Humph, you never play games anymore," She grumbled, even though her brother was focused on his book. "I'd let you pick the game! We could even play that scrambles game!"

"You mean scrabble?"

"Yeah, that one,"

She was going to suggest something else, but as she did the door was kicked open in a flash. Both of the twins jumped up to see the blond haired boy grinning from ear to ear. "Who wants to play a game?" Mabel brightened while Dipper groaned and fell back on the bed.

"Bad timing Will."

"Perfect," Will grinned, walking into the room with something tucked under his arm. He pointed at Mabel with the grin never leaving his face. "Shooting Star, be ready to eat your words!" Once he was in the centre of the room he took what he had out from under his arm and set it in the middle of the floor. Curious, Dipper set his book on his night table while Mabel crawled over so she was sitting next to Will. It looked like a flat plank of wood, but it was covered with a red curtain. Dipper leaned over the bed so that he could see it.

"What is it?" When Will grinned up at him he could almost see his fangs growing.

"My end of the deal." Mabel's mouth dropped open.

"What? NO way!" She shivered in horror imagining what kind of thing Will would make her wear. Whatever it was, it would likely be yellow. And fancy.

Dipper on the other hand, looked at the thing on the ground sceptically. "How is THAT going to make us look scary? What, you got some of Mabel's pictures from when she was still learning how to use makeup?" Both of the twins shivered remembering those days. She'd accidentally used to much waterproof mascara, and it didn't come off for days. Some of it would smudge and her eyes were turned black, bringing horror to whoever was around her.

"Huh, I should find those! But no, this is WAY cooler than some old photos!" With a yank, he drew back the curtain to reveal-a mirror.

"…Not getting the punchline here," Dipper divulged, sighing and flipping back on his bed. Will's frown turned to a frown.

"Oh, I get it," Mabel gasped as she looked down at herself in the mirror. "It's that we already ARE as evil as we are going to get! Haha!" She laughed as she punched Will in the shoulder, making him cough a little. "Nice try Will, but I don't think this qualifies as a win."

Will wasn't happy with them downplaying his idea. "What? No, you don't get it! It's not a mirror doofus's, it's a portal!" Instantly Dipper sprang up from his bed.

"Want to run that by me again," He asked cautiously.

"Aw come on Will, no more portals! Don't you know our family has a bad history with them?" She reminded him, thinking back to her uncle's mind, and the portal grunkle Stan had made, and sometimes she even thought of the bottomless pit as a creepy portal. "The pines and Portals. We are archenemies," she hissed, very serious. Getting down on her hands she got her face so close to the mirror so she was staring directly into her reflections eye. "We will never see eye to eye. Never." Dipper and Will glanced at each other sceptically. Will was about to say something, but Dipper shook his head at him. Just roll with it.

Shrugging that off Will continued, "Come on you two, don't be so negative!" Standing up so he could do a formal introduction, he cleared his throat and pointed to the mirror. "Ever heard of something called the looking glass? Well this is my version of it! It's called, 'the reverse mirror.' Named after you're truly. There's a whole 'nother world in this mirror, where everything is the opposite of what it is here!" With magic he made his cane appear out of thin air and sent it spinning around in the air. "So something bad, becomes good. And something good becomes…" He waited for the twins to answer. Mabel was too busy fixing her hair with the reflection, but Dipper understood completely.

"Something bad." Will grinned and nodded. "So you're trying to find an evil version of us in the mirror that people are afraid of, because no one could be afraid of us right now, right?"

"Right you are pine tree!" Will laughed, leaning on his cane in a cocky fashion. "Come on folks, let's hear the applause!" neither of the twins responded. "What, no one?" They glanced at each other, than shook their heads. "Tough crowd."

Mabel poked at the mirror as if waiting for a white rabbit to jump through. "So, what, everything's supposed to be backwards? Like, even our names? Would I be called something like, labem? That could get confusing." Will rubbed his chin thoughtfully.

"Hm, that's a good point. Here, I'll change it." using his magic he sent a sparkle of magic into the mirror. After a moment the scene changed all the writing went back to normal. "There!"

Taking a careful step closer, Dipper glanced deeper into the mirror. It looked just like any plain old mirror to him. His reflection was the same, except the writing had been turned around because of Wills magic. Other than that though, same old Mable. Same old Dipper. "Dude, I don't see anything," He told Will. The boy frowned and went on the ground so he could look at the side of the mirror. He picking it up and leaning it against one of the beds so it got all of them in the image, but nothing changed. Even Will tried going in front of it, but his reflection was the same as him.

"Maybe it's broken," Mabel suggested, patting her friend on the back supportively.

Dipper, now completely into the mystery of the magic mirror, leaned closer to it. "Are you sure you got the right one? Where did you get this anyway?"

"Let's just say I know a guy," He answered inattentively, tapping on the mirror. "Huh. I thought you were just supposed to look at it and they would appear out of nowhere." He took a step back so he could see all of the mirror and the two twins standing in front of it. Confused, he tried to sort it out in his head. Mabel was glaring daggers at her reflection, even growling at it a bit. Dipper was watching Will with a puzzled expression. Hm…I wonder if I was supposed to send them THROUGH the mirror instead. Glancing at the twins, he wondered it they would be willing to try it…only one way to find out!

"So, let's try plan B!"

"Wait, what-,"

Was all Dipper managed to say when Will got both of the twins by the shoulders and pushed them into the mirror. Both of the twins yelled, expecting to hit their heads and crash the glass. But instead, when they came into full contact with the mirror, it changed like quicksand. The two of them screamed as they were pulled in the mirror, gasping and searching for a way out. The image of their room got fainter and fainter, until they could see nothing but Will's surprised face staring back at them. Then they were gone.

"…Wahoo to plan b!" Will congratulated himself as he kicked at the ground happily. "That was fun. I told you so Mabel! Now why don't you two kids come out of their so we can tell Red just who one this little bet?" there was no answer from the mirror. Will frowned. "Hey! Pine Tree! Shooting Star!" There was no answer. "What, can't you hear me?" Realizing that he was all alone, Will started getting bored. Besides, if the twins couldn't come back, who would prove that he had won his bet? "Guys? I'm coming in!" He called, even though they couldn't hear him. Reaching forward he tried jumping into the glass.

Except for him, he really did just hit his head.

"OW! Human pain! It's not fun!" He wailed, rubbing his head. A horrible feeling came upon him when he realized he couldn't get in. what if Mabel and Dipper couldn't get out? "Uh-oh."

His panicked thoughts were cut short and replaced by different ones when he heard a knocking at the door. "Dudes, dinner is ready!" he knocked again and Will jumped at the sound. Frantically Will looked around him for some kind of escape.

"A-ah, don't come in!" Will called using Mabel's voice. "I-I'm busy! I'm, uh," he searched through Mabel's things to try and find some kind of distraction. "I'm reading…twinkle ponies wish list?" He spoke, his last words coming out as a question.

Soos was just as confused as he was, but knew their uncles wouldn't care. "Come on dudes, I made tacos!

"Really? Oh boy!" Will yipped, then quickly covered his mouth. He'd sounded like himself than. Soos caught on before Will could defend himself.

The door opened to reveal Soos as he was asking, "Will, what are you doing in here," But his voice trailed off. He saw Will. He saw the room all in one piece. He saw a big mirror. He saw two beds, both very messy, and painting tools all around with Dippers favourite book on the night table. But no Dipper or Mabel. Just a very sheepish and worried looking Will. "Dudes! What happened?"

"…We went with plan B?"
