So, sit back ladies and gentlemen the story is about to begin! hiccupandtoothless294 is about to journey into the unknown so who's with me?!

Without further ado let Bill Cipher ' s return commence!

Chapter 1 Return to the Falls

Dipper tossed and turned in his bed mumbling something under his breath.

Dipper found himself running through the woods, but what was he running away from?
That was until he crashed into something. Dipper groaned as he rubbed his aching head.

"What did I hit?" Dipper grunted as he looked up. "Hey there Pine Tree. Long time no see." Bill said. " BILL CIPHER! I-IMPOSABLE! Grunkle Stan defeated you! We defeated you!" Dipper gasped as he tried making a beeline to get away from Bill.

"Pine Tree Pine Tree Pine Tree. Come on know let's not jump to conclusions, I've changed. I learned from my past mistakes. I have had so long to think about it." Bill said deeply. "You...have?" Dipper asked in nuisance.

"Dipper, would I lie to you?" Bill asked as he floated around Dipper ' s head. "Well yeah you would. You're an isosceles triangle who makes deals, possesses people for your own benefit and nearly destroyed Gravity Falls and my family! What makes me believe a guy like you? I don't believe you've changed Bill Cipher because you'll never change!" Dipper snapped as he punched Bill.

Bill flew into a tree groaning. "Look Pine Tree you don't have to believe me. I get it after everything I did to you and your family. But I don't have my magic anymore and I've been so lonely and I just thought that maybe you'd be my friend. But I guess I was wrong. I'll show myself out, sorry for wasting your time." Bill said as he started floating away.

"Bill wait!" Dipper said holding out his hand. Bill looked at Dipper then at his hand. "I'm putting a lot of trust in you Cipher, don't make me regret it. Deal?" Bill took Dipper ' s hand. Then a blue flame wrapped around their hands.

"What I thought you said that you didn't have magic!? You lied to me!" Dipper snapped at Bill who laughed. "You're kidding me Pine Tree how could you be so gullible twice. I didn't have my magic before but know that you've broke my chains I'm free. I'll be back to Gravity Falls Dipper and you'll be my first victim after all you and I make a stronger team then apart. See you soon Pine Tree!" Bill said before disappearing.

"Ahhhhhhhhhh!" Dipper screamed as he sat up straight looking around the room. He was alone. He was in his dorm room at his collage. Years had come and passed without any problems and he had gone on adventures with Ford, Soos, Wendy, Stan and..." Mabel. I should give her a call." Dipper said as he looked down at his clock. It was 3:30 am where he was which meant it was 6:30 pm where Mabel was. He got out of his bed and walked over to his laptop and opened Skype and called Mabel.

"Dipper? What are you doing up at 3:30 in the morning, did something happen? " Mabel asked when she answered. "Also hello."

"Hey there sis, I hope I'm not intruding anything important. " Dipper said giving her a soft smile. "No actually I was just about to order some food and study for an exam. But I've got some time to kill. What is up. You look terrible." Mabel commented. "Mabel...Bill Cipher is alive." Dipper said with a serious tone.

Mabel put down her pencil and paper she'd been holding. "Hold on. Guys if you don't mind starting without me I have to take this call." Mabel hurried out of her dorm room down the hall to a private room. She sat down on a couch and put her laptop on the table in front of her. "Dipper, Grunkle Ford erased Bill from existence. There is no logical way or phenomenon that could possibly lead to Bill being alive." Mabel explained.

"Then why did he show up in my nightmare I just had. And it's because of me he's got his magic back. I-I shook his hand. I've just doomed our family. He's going to come after me Mabel. We have to get back to Gravity Falls. We'll be safer there then when we're in two different parts of the world." Dipper said.

"Dipper we don't even know if that was Bill you saw in your dream. Besides I can't just pack my bags and fly out to meet you in Oregon I have classes and so do you. If you're so worried about it why was I the first one you called? Why not have called Grunkle Ford?" Mabel explained with a frown.

" Because you're my sister and you of all people should kind of figured I'm not lying about what I saw. Besides I can only Bill proof my dorm room so much Mabel." Dipper said uneasy.

"Oh... shit, you're really serious about it, well then, in that case, I'll have to definitely come join you if you're that paranoid about it. I'll see you in a few hours Dipper you'll pick me up at the airport, right?" Mabel said. Dipper nodded. "See you soon Mabel."

They ended the call and Dipper breathed a sigh. 'What the fuck was I thinking in trusting Bill?! Was he controlling my mind? Where has he been all these years? What is he planning?'

Dipper ' s brain wondered over the possibilities all the way to the airport.

Dipper waited at the arrival gate waiting for Mabel to arrive. Thankfully she had been able to grab a ticket for a flight at 8:30 pm her time 5:30 am his time. The door opened and a young girl with a pink zip up sweater and jeans walked outside the door and smiled when her eyes landed on Dipper.

She went over to him and took him into a hug. "It's been to long since we last saw one another Dipper. "Mabel said. Dipper sighed as he hugged her back. "No kidding, college is a pain. Expeally when we're in two different parts of the world. But I have to thank you for coming all this way. We should get going." Dipper said as the twins walked out of the airport to Dipper ' s car.

"What?! Is that really your car Dipper?!" Mabel asked when she lied her eyes on Dipper 's blue Ferrari. "Yeah, I mean what other car would I have? "Dipper asked in question. "I don't know but where did you get the money? " Mabel asked. "Does it matter Mabel?" Dipper grunted as he got in the car. Mabel put her luggage in the car with Dipper's before sitting in the car for herself.

The ride to Gravity Falls was full of questions and stories of how school had been since they left home to go to school. Dipper had stayed close to home for schooling while Mabel had moved out east.

He would always look back at their childhood where they'd go to Gravity Falls every summer after the first time they went. Dipper would spend time with Ford and would learn more about Gravity Falls and other things, Stan and Ford would tell stories of their adventures out at sea. Wendy and Soos would voice crazy comminatory and over all everyone had grown to be great friends.

Life seemed like it was nothing to worry about since Bill had been destroyed but know Bill had returned somehow and now it seemed like all the peace that came to Gravity Falls and their family was about to come to the end.

Why was Bill back? How was he back? What did he mean when he said the things he did in Dipper ' s head?

Dipper hoped to get the answer when he got to Gravity Falls, organ. But something in the back of his head told him: if you return to Gravity Falls Bill gets what he wants. Dipper was nitpicking at the thought and what significance it had to the bigger picture but none of his hypothesise made much sense or didn't connect in any way, shape, or form. So, what did make sense? What was he missing here?

Time passed as the twins saw a familiar land mark. The Gravity Falls water tower. They had made it. "Welcome back Mabel, to Gravity Falls." Dipper said as he smiled.

"You said something about skyping Grunkle Ford back in September, about some weird rock you found?" Mabel said. Dipper rubbed his head. "Yeah," Dipper said hesitantly. "Something like that." He went on to say. When in reality he had actually called Ford about the dreams he had been having about Gravity Falls falling into ruins just like when they faced weridmagedon and about him feeling more tired and weak.

Ford said he'd do some research on it and get back to him and that was a month ago. Well know things had escalated and he had to get back to the falls.

As Dipper put the car in park both twins stepped out of the car and took in the Mystery Shack. They where back. Both took out their suitcases and took each others hands. They looked at one another. "Ready to adventure into the great beyond? " Dipper asked his sister. "No, are you?" Mabel said giving him a quick laugh. As they remembered what they had said long ago.

The twins walked forward and into the Mystery Shack. A young red-head looked up from her book and her expression changed. "Do my eyes deserve me? Dipper, Mabel? "

" In the flesh. It's been awhile since we last saw one another in person, Wendy." Dipper said giving her a warm smile. Wendy raced out from the counter and embraced the Pines twins. "It's been ages guys, how are you here? Don't you have college and jobs of your own? Mabel, shouldn't you be on the other side of the country? " Wendy asked.

" Something happened to Dipper Wendy and if he's right it could mean destination of our family." Mabel hurried to pipe in. Wendy was taken aback at her statement. "What happened Dipper? " she asked looking at him.

He looked up to meet her glance. "Bill Cipher has returned."

"What did you say? " Came a voice from the other room out of the door came Ford. "Bill Cipher, alive? The numbers don't add up."

"Scientifically they shouldn't however this is an evil dream demon we are talking about here. Science can't begin to explain anything about Bill." Dipper explained shaking his head in one soft motion.

Ford moved over to Dipper before lying a hand on his shoulder. "Come we have much to discuss in my lab, I want to hear about it and hopefully we can come up with a hypothesis."

"But Mabel -" Dipper tried to speak. "I'll handle things bro bro don't you worry about it." Mabel said as Ford led Dipper downstairs.

Once downstairs Ford began looking for a pen. "Sorry about the mess, I wasn't expecting company."

Dipper smiled as he ran his hand over the equipment he had learned to use for years. "I missed this laboratory, it meant so much to me when I would come to see you all every summer. Even being in the best college for science and technology in the state it can't compare to your lab and what you've taught me all about down here. I mean...the whole fact of what we've ever learned in science I knew all the answers to the questions and I'm in the second year of college. But with the dreams, withdrawals and now Bill showing up it wasn't just a pure coincidence. I've had the same nightmare for years, the withdrawal into the end of high school and all through college. So, what is your thoughts Grunkle Ford?" Dipper asked.

Ford looked up at him from looking for a pen. "Well, Dipper, I'm not sure how all of these, " he rolled his wrist as if looking for the right word. "phenomenon's have to do with Bill, maybe not every phenomenon the nightmares are his type of thing. Other than that, I've never heard of the withdrawal symptoms before. Remind me again about them." Ford said. "Ah ha! Found the pen!"

Dipper couldn't help but chuckle at his Grunkle Ford who smiled back at him as he then grabbed his pad of paper and his laptop.

They both sat down in a set of chairs. Dipper went on to explain. "Well to start out with I feel like I lose most contuses and feel like I'm seeing the world from behind glass. The next thing is I get these yellow rings around my pupils. I feel super tired after its over and lastly I don't have control over my body at all when it happens."

Ford looked up from the paper. "You neglected to inform me that you don't have control."

"Didn't I say that to you when we had talked about it?" Dipper asked confused. Ford pulled up some notes on his laptop. "Yes you did, sorry about that." Dipper took a breath. "So what did you learn about it?"

"Not much. I came up empty. Sorry Dipper." Ford muttered sourly. Dipper went to rub his neck when he stopped they both did.

The next thing they knew they where in the woods of Gravity Falls. "How on earth did we-?" Ford said. "RUN!" Dipper snapped as he grabbed his Grunkle. Both ran through the woods. "What are we running from Dipper? !" Ford managed to shout out as they ran.

"I don't now, I never now all I do is run, welcome to my nightmare! " Dipper shouted out over his shoulder. Ford pulled away from Dipper. "What are you doing! We have to keep running! " Dipper cried in destress. "No Dipper the Pines don't run! We stand and fight." Ford said as he pulled his gun.

The sky over head opened. "Well well I got Pine Tree and IQ in one go this is just too good."

Dipper froze solid with fear. Ford whipped around to face Bill. "You're alive, but how!?"

"Don't play dumb IQ you knew I'd be back. I've been busy with getting my strength and power back after that brother of yours destroyed me. But I helped him and myself. But I'm going to leave it there. I look forward to my plan playing out. See you soon, Pine Tree. Hahaha ah hahahaha. "

Ford shot at Bill but it missed its mark as Bill disappeared.

Both gasped as they regained cortisones. "We feel asleep? " Dipper asked. "Bill...what are you planning! " Ford screamed with fury.

Dipper winced away from Ford. "Grunkle Ford we know Bill more than anyone in our family. We know that what ever he's planning has to do with Bipper, his business is with me. For what I am unsure of right now. However, if his intention was to go after me to get my body he's got another thing coming. He can't take my body without me shaking his hand."

Ford shot Dipper a glare. "I'm not sure if that's true anymore. " Dipper tilted his head to the right. "What on earth are you talking about Grunkle Ford? Bill can't take my body without me shaking his hand. Right?" He asked with confusion. Ford's posture slumped. "In this case, I don't think so. I had a feeling that Bill wasn't dead. That he had found a host to seal himself inside. I didn't think it would be you. But it all makes clear sense. Every summer we would practice your skills in spells, potions, the whole thing. Little did I realize that the reason you picked up on several of the subjects impractically was because they were skills Bill possessed, it makes sense why you took his deal in your dream. It's because he had you wrapped around his finger." Ford punched the wall. "I taught the monster. Dame it...dame it! How the hell could I have been so blind?!"

Dipper stood their modified. "B-Bill...was in my head for six years. Learning everything I have ever done, watching every relationship I had growing up?! No wonder why nobody stayed around me long. Bill was there when Mabel and I fought about college. He-" Dipper tried to breath but the anxiety was overwhelming him.

Ford rubbed Dipper ' s back. "We didn't know Dipper, even the smartest of us miss important details. Dipper, Bill doesn't need to shake your hand anymore he's a part of you and there is nothing I can think of that could stop Bill without hurting you."

Dipper grabbed Ford's arm. "I don't care about my mind right know, do whatever it takes to get him out of my body!" Ford frowned. "It's not that simple Dipper, his soul is intertwined with yours. I'd have to look through my research but this never happened before."

Dipper looked down. "I'll help you look." Ford shook his head. "No, judging by the bags under your eyes you haven't slept well. Go get some rest, you can sleep in your room up in the attic or down here." Dipper yawned. "To be honest I think down here for two reasons. 1) it's darker than upstairs, 2) if something happens I can trust you to deal with it." Dipper said.

Ford nodded his head. "Yeah, you can rest on the caught I have down here. Sleep well Dipper."

"Thanks Grunkle Ford. See you when I wake up." Dipper said as he walked over and laid down. Within seconds of his head hitting the pillow Dipper was out cold.

Meanwhile

"Okay let me get this straight kid, you think that Bill Cipher, the isosceles triangle that wares a top hat, bow tie and has one eye is back?" Stan said as he asked Mabel to clarify her statement. " I'm about 50% sure no make that 90% sure Dipper doesn't lie Grunkle Stan." Mabel said.

Just then Ford came out from his lab. "I don't have very long because I need to get back downstairs however I wanted to inform you all of what was going on and the news isn't good. It seems when Bill was destroyed he hopped into Dipper's body instantly making Dipper a host body for him seeing as his original was destroyed and turned to stone. He's been here for 6 years and we didn't even know he's been there in Dipper's mind the entire time. We don't exactly know what he's planning but it has something to do with Dipper and Bill's puppet form of him Bipper."

Wendy, Soos, Stanley, and Mabel all just stared.

"Impossible, Mr. Pines destroyed him." Soos cried outraged. Ford put up his hands. "I am aware of this, however that didn't stop bill. I need to get back to make sure Dipper's alright however no one is to come downstairs. I don't want to risk something happening. Does everyone understand? "

"But I-"Mabel tried. "Sorry Mabel it's to keep you safe and same with your brother." Stanford said in a serious tone. "Okay Grunkle Ford." Mabel reply reductively.

Ford turned and closed the door.

Mabel looked at Stan. "You want me to tell you where the secret camera is for downstairs don't you?" Mabel smiled. "Okay fine, its in my office. Be gone with you child I have a business to run, and you two get back to work." Stan said.

"Yes Mr. Pines." Wendy said with a grunt while Soos nodded. Both went off to do their respective jobs. While Mabel headed off to Stan's office. Once she was there she pressed a blue button which moved up a panel and reveled screens with the downstairs lab. Mabel saw her brother sleeping while Ford read through several books. His new journals being among them. Ford had re written the journals after bill had destroyed them. In fact, he had made a forth book as a second copy of journal 3 strictly for Dipper for their 14th birthday. Dipper was so excited to have his own copy of the journal 3 and he couldn't stop smiling about it. Know in retrospect it seemed as though it was a bad thing, if bill had been in Dipper this whole time he'd know everything about Gravity falls and what had been hidden in journal 3's pages.

Dipper started to fuss and thrash in his sleep. Ford looked up from his books before racing at him there was no sound. Suddenly a blast of blue flame engulfing the lab blinding Mabel.

"DIPPER!" Mabel shouted. She jumped from her seat as she raced to the door to the lab. She tried heaving it open to no success.

Downstairs

Dipper fussed and thrashed in his sleep. "Hitro metria siloti,"

Ford looked up from his books upon hearing speaking. Once he realized that it was Dipper he shot up from his seat. "Noooo!"

"Hitro metria siloti, Hitro metria siloti." Dipper chanted. A blue flame engulfing the lab shallowing both Dipper and Ford.

Ford shied his eyes as the flames licked at his body burning him. He had to get to Dipper. This magic felt all to horribly familiar to him. "Let him go, Bill!"

The flames stayed but cleared enough so Ford could see. Bill floated next to Dipper's body. He had yellow eyes. Behind them ways a still body of Dipper who was see through.

"Hi there IQ, just wanted to pick up my puppet then get out of your hair. Thanks again oh and so that way pine tree is safe I'll do him a favor." Bill shot a bolt of energy at Dipper which made him disappear. "Dipper! Where did you send him!?" Ford snapped. " To the nightmare realm where else. Bye for now IQ." Bill said as he and Bipper disappeared.

Ford fell to his knees as his body smoked before hearing cries before the world slipped away. "Dipper, forgive me." Ford whispered as he passed out from pain.

A/N: Hey there guys, so yes some things maybe spelled incorrectly, I have issues with my spelling and grammar, even though I can read and write very well, I just struggle with spelling words correctly. So yes, you can point them out but do it in a way that it's like "YOU SPELT THIS WORD WRONG." Kind of thing, just say: "Hey this is how you spell this word."

I also can get side tracked very easily when I write stories because I feel like dragging things out, if I start doing that let me know.

If anything is confusing I will do my best to explain however I'm not good with time zones in the states sooo yeah if any of that seems weird it's because I was lazy not to look stuff up while planning this opening chapter. If you guys feel I should do more research and also use the information that I have from my journal 3 book I own let me know as well.

Feel free to make suggestions to this story, what needs fixing or what you would like to see added to the story.

Let me know what you thought about this first Gravity Falls story.

Thank you guys please review this story.

Until next time, I'm hiccupandtoothless294 signing off to go hang out with Bill.
