Chapter 1

Hello everybody! (I'm sure no one will actually read this...) This is just a little idea that one of my best friends and I came up with. You see, we dressed up as Bill and Will for Halloween (I was Bill, she was Will) and we were thinking "we need a backstory on why" and thus this amazingness was born. This is not our first fanfiction, but it is our first "published" one. We hope you enjoy! I would love any feedback, even if it is slightly harsh. Oh, and of course we don't own Gravity Falls. We do, however, own the story as well as Liz and Lex. If you would like to mention them or use them pm me? I don't know why you would, but I mean, whatever. This is rated T just to be safe for now. However, it may live up to, or possibly exceed that rating and be changed to M. I would just like to warn you now, in case that's not your cup of tea. (also, I'm only saying that because though the whole thing is planned out, it's not all written. So yeah. I don't know what else I was supposed to say other than this... so yeah...) Oh! The characters will most likely be OOC... I'm sorry if you don't like that... also our OC's are a thing... so same with that I guess. Anyways, here is chapter 1 folks!

Please, enjoy!

"Bill… I'm really scared those twins will find us here…" Hesitation was clear in Will's voice. He knew his brother wouldn't yell at him -he never had- but hesitant in asking for things. Even from his brother. "Maybe we could… switch dimensions…?" Will added in an attempt to get his twin to move with him for Will to keep him company and for his twin to keep him safe. Little did Will know, Bill had already been planning to bring up that same point to his brother later that day.

Bill wanted revenge on the Pines' family for banishing him from the universe that contained Gravity Falls. He quite liked it there.

"Well, brother, I think that's a fine request! It has been getting rather boring around here." Bill finally replied. Bill didn't know all his twin had gone through in the grasp of the Reverse Pine's hands, but he knew enough to want to keep them alive long enough to be sorry for what they did to his twin. And then some. His "twin" was actually him from another universe, but since they had such different personalities, and they didn't go by the same name, they had a long conversation about how they could live together, rules they both had to go by, and that, though they were technically the same being, they were not, in fact, the same person. Or demon, whatever.

"Really? I … didn't think you'd be so gung-ho about it right away. I was sure I'd have to convince you or make a deal or something crazy. Don't get any ideas." Will could be a sarcastic ass when he wanted. Will was soft spoken, well, to anyone who wasn't Bill. He was shy, and, from his time with the Reverse Pines, he was paranoid and skittish. He often had nightmares and panic attacks.

Bill had agreed to let Will live with him, until they thought of something better, but, though neither would admit it, they rather enjoyed living together.

They were polar opposites. Unlike Will, Bill was very outgoing, loud, and overall highly obnoxious. He was stubborn as all hell and if he had an opinion you'd know it. However, though they did have their differences, (major differences), they were inseparable.

For all their differences, they also had many similarities. Both were sarcastic, -when Will is in a good mood, of course- both posses a terrifying amount of power, they were both stubborn with each other, and they were very protective of one another. Though they'd never admit to it.

"Well, brother. As I said, it's boring here. I want revenge on almost every version of the Pines' family and staying here will do nothing to further my plans. In fact, if you hadn't just brought it up, I'd have suggested it myself." Bill stated, his eye scanning across the pocket dimension they called home at the moment. There was no use lying. They practically were the same being and they would know if the other was being untruthful.

"Oh...Okay, brother…Well what do you have in mind?" Will asked.

"We make some deals, my good brother!" Bill replied with what was sure to be a grin if he had a mouth.

"Oh… Who do you have in mind?" Will asked, slight trepidation could be heard in his voice. Bill savored this time talking to Will because he knew that Will would talk even less when they left their cozy pocket dimension. Will may even just use the mental link and not talk out loud at all, it was to be expected, and Bill mentally prepared himself. Bill could also be a slight pessimist. He just liked to plan for the worst. Then, he was either always prepared, or always right. So it was a win-win.

"Well, brother dear, I do believe twins would be appropriate don't you think?" Bill said, no doubt smirking in his mind.

"Yes…I think that would be best…" Will agreed, glad that Bill already had a plan for when they left. They couldn't stay here forever, the Reverse Fall twins were trying to hunt him down as they spoke so the sooner they left the better.

"Then let's be off, brother! Pack what you need. We won't back here for a while, if ever." Bill popped away in a huge cloud of smoke, presumably to pack his own whatever. Through the mental link they shared he added, "We leave within the hour!"

Will sighed, then smiled. His twin always had to be dramatic. Oh well, at least they were going to gain more distance from the Reverse twins. But moving wasn't going to stop them from tracking him down. It was only a matter of time before-

Will quickly pushed the thought out of his head, now wasn't the time for a panic attack. Will poofed to his room to pack his few belongings.

How was that? I hope you enjoyed! anyway, I wont do the "I need 5 reviews to post the next one" however, I would love a review/ your thoughts on this chapter! I'm sure my co-writer would as well! we are open to suggestions as well if you are so inclined! Have a beautiful day/night/whatever.
