Other Dipper turned the coin over and over in his hand as he and his counterpart walked back to the shack, several yards away from Mabel and Ford. It felt strange to him, being this close to the other him. It also felt... wrong. This was never meant to happen. They were supposed to stay in their own respective universes, but this one and his sister had completely disregarded that fact and strayed in anyway.

Other Dipper shook his head. Or, technically, Bill had disregarded this fact. Despite never actually seeing or meeting this Bill character, Other Dipper had the feeling that Bill wasn't really one for rules. He couldn't really blame him.

Dipper kept glancing suspiciously at the other Dipper. At the moment he didn't seem to be plotting anything malicious, but that could just be a disguise, or him just biding his time. Anything could be going on in that twisted mind of his. Dipper shivered as he remembered the more gruesome memories the other Mabel had implanted in his mind. They were slowly fading the longer he stayed in his home dimension, so that was a relief, but the gory ones still held on fast.

Other Dipper sighed. "Alright, I know we said we weren't going to talk about our times in the other dimensions, but I have to say, your sister is crazy." He said blankly. Dipper turned to look at him. "Seriously? You think my sister is crazy?! You should take a look at your sister before making any statements like that."

Other Dipper breathed fiercely through his nose. "Okay, my sister is not that crazy." "Really? Your sister knocked me out and tried to make me your replacement." Dipper replied. "Not to mention her fascination with knives, her general creepiness, and her absolute hatred towards Paz." Dipper added. Other Dipper opened his mouth to reply, but found that he had nothing to reply with, so he closed it.

"Whatever," He grumbled. "It's not like you'll ever see her again, anyway."

Dipper snorted. "Doubt it." He said. Other Dipper crossed his arms. "What do you mean?" "Well, Tad said that the only way to get you home is for your sister to come here as well." Dipper explained. "That means she's going to pop up here at some point."

"No, it just means I'm going to be stuck here for the rest of my life." Other Dipper replied. A beat of silence. "Wow, aren't you a negative nelly." Dipper responded. "It's not being negative, it's being realistic. I can't create a portal on my own, just like my sister can't." Other Dipper explained. Dipper shook his head. "That doesn't mean she's never going to show up here. Sometimes unexpected things happen." He shrugged.

Other Dipper sighed. "I guess..."

Mabel Gleeful paced throughout the living room, the fire in the fireplace being the only source of light. It gave the room a fiery orange glow. She mumbled curses under her breath and went from one side of the room to the other, making long, furious strides.

There were three other occupants in that room. Will stood by the doorway, fighting to stand without swaying as blue blood dripped down from his newly made wounds. His face and arms were bruised and his cheeks glistened with tears.

Gideon and Pacifica were gagged and tied up next to him, sitting on the hard wooden floor. They struggled to escape their bonds, but didn't dare make any noise. They were also slightly bruised, a black eye forming on Gideon's left eye, and Paz's sweater being slightly ripped, revealing a few bleeding cuts on her sides and arms.

Mabel fought to keep her breathing steady. She fought to keep her emotions under control, for once in her life. Her brother made it look so easy, how did he remain so stoic all the time? She knew if she grew angrier than she already was, she'd probably end up hurting Will more than she already had. Not that she cared, but she preferred he didn't lose consciousness from so much blood loss.

In fact, Mabel looked at Will's wounds and drew a circle in the air. Suddenly, bandages appeared on all of his cuts, on top of the ones that the counterpart had placed before he suddenly went missing.

Will looked at her in surprise. She glared back at him and he immediately went back to looking at the floor. She resumed her pacing, her brain struggling to find any way she could get her brother back. She had tried to go through the journal her brother always looked at, but nothing about jumping dimensions was mentioned. She'd even gone through the one Gideon held, but still, nothing.

She had no idea where the first journal was, but she assumed that there anything helpful in that one either.

She quit pacing and turned to her captives fiercely. "What did he last say to you?!" She yelled, finally speaking after almost an hour of pacing. Her legs were starting to get tired and her feet began to cramp up.

Paz and Gideon muffled incoherent explanations through their gags. Mabel exhaled heavily and ripped them off with her telekinesis. Gideon was the first to speak. "All he said was that he had some sort of deal to make with a demon. I have no idea what he meant." He added before Mabel could ask. "Oh. I just remember him asking me if I could share my cookies with him." Paz replied.

Mabel groaned. "Not helpful whatsoever." She resumed pacing, even though her legs were screaming at her to sit down. She couldn't bare the thought of sitting still. "Well, how can you expect us to help?! And why would we even want to help you? So far, you've broken into our home, you beat and tied us up, and now taken us prisoner in your home." Gideon responded. "Would you have come willingly?" Mabel retorted. "No, definitely not." Gideon said firmly. "Also, I think the beating us part was a bit of overkill." Paz added.

"Just be glad I don't overkill you." Mabel growled. "If I may," Will started timidly. Mabel turned quickly and threw a knife that landed two inches from his left ear, causing him to shriek. He went silent. She sighed after a few moments and curiosity won over. "What?" She asked impatiently.

Will cleared his throat and stepped away from the knife in the wall. "Uh, I may know who Dipper made a deal with." "Who?" She demanded. "W-Well, he said... he said that he had a deal to make with a demon. Then he disappears. So, I'm assuming that whoever he made a deal with was also the one to bring him here in the first place."

Will explained. "And who would that be?" Mabel asked.

Will shivered. "It was probably Bill." He mumbled, just loud enough so they could hear. "My counterpart." He clarified, seeing the confused faces that followed his statement.

Paz's eyes lit up. "Oh! He's that demon dude that Mabel and Dipper told us about! Wow, I kind of expected him to have a more threatening name than Bill." She said. "Wait, and Dipper made a deal with this guy?" Gideon asked. Will shrugged. Mabel shifted her wait to her left hip as she thought this through.

Will had a counterpart. And Dipper had made a deal with him, most likely one that sent him home. So... if she wanted to get to her brother and the counterpart... she'd have to go find this Bill, and make some kind of deal with him as well.

She stood straight and crossed her arms, staring at Will, her jaw set firm. "How do we summon this demon?"

—————————————————————

Uh oh. Looks like Mabel will be visiting Gravity Falls much sooner than Dipper Gleeful thinks, and much sooner than Dipper Pines would like.

Anyway, wow, would you look at that, posting so soon? Nice.

I literally just had this burst of creativity and got this done in one sitting. Also, if it's not clear, I'm leading up to the big climax. The whole boom, pow, ka-boom thing.

Anyway, I hope you enjoyed it, and I'll see ya later, entertainers!
