Next day, morning in the mystery shack. Dipper,Mabel, (y/n), will and bipper was on the dinning room.

"Woah. These hands are still adorable that i remembered...." bill said looking at his hand which was holding a fork. Dipper was behind bill as he folded his arms. "Just don't do anything that involves pain with my body....."

"Sure...., i'll take care of your body pine tree.... don't worry about a single thing" bill's voice turned into a demon voice on the last part as Dipper winced.

Bill chuckled. "Nah. I'm just kiddin'!"

(y/n) appeared then slapped bill's right cheek. "Ow! Seriously! Why do you keep on doing that?!"

"It's a sign that you shut your mouth up!"

"Then i'll give you a sign..... i'll give you one.... soon...." bill says squinting his eyes.

(Y/n) slapped his left cheek. "Oww!"

"What's wrong triangle man? Are you crying because of pain?"

"What?!! Why would i even~" (y/n) slaps bill's face. "Oww! Seriously! You have got to stop that!"

(y/n) slaps bill again. "Never!"

(y/n) was about to slap bill again but he held (y/n)'s wrist. "Don't. Ever. Do. That. Again." Bill stated with a demon voice.

The others sat on the table eating nachos. Mabel was beside will. Bill was beside (y/n). Dipper was somehow floating in the air. Wishing that someone would see and talk to him. The table had a bowl of nachos, pancakes, syrup, bowl of melted cheese, mabel juice, glass cups and plates.

(y/n) yawned in exhaustion cause she spent the rest of the night trying to ignore bill's talking cause well dream demons don't sleep even if they posses someone. When bill gets bored. He usually annoys anyone for entertainment even his daughter.

(y/n) accidentally lifted up the container that had mabel juice in it without knowing. She poured it on her glassed cup then drank it. Will was disgust, dipper was weirded out, mabel was happy cause she thought someone finally would like her mabel juice while bill sat there looking at his daughter a bit confused and weirded out cause (y/n) accidentally drank a plastic dinosuar.

(y/n) hasn't swallowed it then realized something. She looked at the container revealing the mabel juice. Her eyes wided. She spitted it out on the left side which bill was on. "Ahh! Gross! (y/n)! Seriously?!" Bill says moving away carrying the chair as he moves away. Will laughed as dipper was a bit entertained.

Mabel sighed sadly. "Nobody likes my mabel juice..."

Stan appeared then sat beside mabel on the left. Ford sat beside bill on the right side. "Hey dipper." Ford smiled at bill not knowing that bill was inside his nephew's body. Bill frowned. "Stanford..." he growled. "Dipper. Is something wrong with your eyes? It kinda looks like~" (y/n) covered her father's eyes. "N-nothing's wrong with this meatsacks' eyes. T-there's probably just dusts in his eyes. Nothin' to worry about sixer!" (y/n) grins widely in an innocent way. Ford decided to not mind his nephew's eyes as (y/n) took off her palms.

"You sound a lot like bill. Oh and dipper. I need to talk to you about the infinity sided dice. It's operating weirder than i thought it would be. Probably it's signing an affect that the end is near and i~~~" bill didn't quite pay attention cause he already knows where everything or everyone is and what they're doing. He knows what'll happen in the future because of his power of precognition of potential scenario. And he already knows what's wrong and what an substance or object can do by the power of telekenisis. Believe me. Bill cipher has a lot of abilities that are really shocking.

Bill rolled his eyes in irritation and mumbles. "So this is what it feels like to be..... bored to death."

"What was that dipper?" Ford questions. "Nothing! Oh he said nothing! Just sayin' that he's super Excited! To get the job done!" (y/n) grinned widely. "Oh about your father. I'm sorry but he needs to be destroyed. He can destroy our world by just a flick of a finger. I swear i will destroy him no matter what happens!" Ford gritted his teeth as he clenched his fist. Bill started glaring. "Well i'll like to see you try....." bill mumbled under his breathe.

" Bill is a cunning, eccentric, insane, psychopathic, and physically irreverent demon who finds most things amusing. He's outrageous and outlandish, as well as a quick talker and thinker. Though he may come across as simply annoying, he shouldn't be underestimated; for when he is angered, he's a force to be reckoned with as he will unleash his near-omnipotent powers on those unfortunate enough to make him angry. When accused of being insane, Bill, proudly, agrees with the statement. Bill is not one who believes in rules. Instead, he follows his own selfish philosophy which means doing whatever he wants without care for the consequences. He's a liar. Monster and a snappy dresser!" ford said as bill's heart was screaming in anger and hate as his kids were trying to hold their laugh with the last part. Liar. Monster. Snappy dresser.

(y/n) remembered that When Ford accidentally stumbled into a strange cave, he discovered the painting about a "being with answers." Desperate and naïve, Ford ignored the warnings and read the summoning inscription, but was confused when nothing happened. Later that day, while taking a nap, Bill entered the man's dreams. Bill deceived the man, telling him that he was a muse who chose one incredible person every hundred years to inspire. He told Ford that if he sided with Bill, they would unlock the greatest riddles in existence. Blinded by this flattery, Ford believed Bill to be a friend and agreed to the deal.

Ford seemed to idolize Bill and decorated his home with various images of him and a similar symbol, the Eye of Providence, which can be seen scattered across Gravity Falls.

Will remembers that the page of the journals. Reminding him about Stanford's words about hi. " Bill has proven himself to be one of the friendliest and most trustworthy individuals that I've ever encountered in my life. What a guy! I honestly can't trust him more. Not evil in any way, Bill is a true gentleman." However, the latter note is crossed out and below another note reading "Can't Be Trusted!" can be found written in red ink. On the next page, a diagram of a human head and various aspects of its mind is shown, its top being opened up for a drawing of Bill to enter it. In the lower right corner of the page "DO NOT SUMMON AT ALL COSTS!" is written in large, red letters. The rest of the page is spattered with a dark red substance.

"Why you six fingered!~" Bill stood up but his wrist was grabbed by his daughter. He turned to see (y/n)'s pupils changing forms of objects like fire, meteors, stars, planets getting blowned up into blitz and chaos and destruction everywhere.

Bill scoffed. "You do know that doesn't scare me...." bill sats on the chair once again rolling his eyes.

"Yeah i know. Just wanna see if you get frighten.... pine tree....." his daughter grinned widely as she mentions the name. "Hey! We've talked about what's the meaning of pine tree okay?!" Bill said mentioning about what happened ten years ago. When (y/n) accidentally called her father "pine tree".

"What's the meaning of pine tree?" Mabel asks as she shoved a nacho inside her mouth. "Weak and easily can be harmed...." will answered wiggling his eyebrows as he folded his arm as he drapped them on the desktop.

"Hey i'm not a pine tree!"

"Well you are!" Mabel answered dipper grinning widely. "Do you believe in ghost as in real ghosts?"

"Well i believe that you're a dork!" Stan and ford remained confused. "Who are you talking to?"

"Umm.... dipper's new friend! Dippilina!"

"Sorry what now?" Bill asked quirking an eyebrow as he was drapping his hand on the desktop. (y/n) dragged bill to her by gripping bill's shoulders. "Listen. Just play along if you want to keep that body...." she whispered on bill's ear.

"What do you mean? I hate this dumb worthless body!" Bill whispered back. "Well you need to shut up and let me do the talking!" (y/n) whisper/yell as she push bill's back as bill was moved near ford. Ford remained confused.

"What up fordy! How's it going?" Bill asks cheerfully trying to act natural. "Umm... dipper? Are you alright? You act like someone i know...." ford squinted his eyes as he looked at bill. Bill remained wincing. (y/n) popped up on the middle. "Woah. Look at that! Nachos! Now isn't this fun?" She stated chewing the nachos. Bill looked at those things.

"What's a nacho?" Bill questions. "Triangle food." Will answered. "Mortals eat triangle food?" Bill asks as ford was literally confused right now. "Dipper, you're acting strange...."

"What?! No! He's not acting strange! He's tired! He had trouble sleeping!" (y/n) lied grinning widely as she looks at ford squinting her eyes cheerfully. "Are you hiding something from me? What do you think stanley?" Ford asks stan who was reading new paper.

"Nah. Whatever. Let the kids do what they want. It's nature."

"Nature? I'd say it's puberty! Hey shooting star! Wanna know what happens when your brother had puberty when he was about 15 years-old?" Bill asks as he blinked his left eye first before the other one. Ford recodnized him. "Bill?!"

Bill chuckled. "Wow. New record for the six fingered-freak! Didn't think you would figure it out for real.... so what do you think of my look as this?" Bill asks grinning widely. "Will. (y/n). Does your father really have to talk that much?" Stan asks. "Shut that imitating mouth of yours stanley!" Bill death glared at stan.

Ford pulled out a gun then aimed it at bill. Will blocked the way. "No! That's dipper's body! If you cause the body injuries it may affect dipper!" Ford sighed in defeat. "Alright. Remember bill. Today. We're friends.... but by the time the deal's off.... we're enemies.... understand?" Ford says frowning.

"Yeah. Yeah. Don't get too over-excited if i leave this worthless body.... and besides kinda getting used to it...." bill grab a fork then stab it on the pancake nearby. "Almost...." he adds.

"Listen. If the deals off. You leave my family alone!"

"Alright. Yeesh ford. Get a hold of yourself.... i'm not gonna do anything that involves chaos and destruction....."

"Yet." Bill says grinning widely. Ford squinted his eyes. "Fine. But keep out of my sight..... i don't know how much i can handle staying with you..... demon...." ford left. "Pfft. You're no fun sixer!" Bill said as dipper glared at bill. An idea popped inside bill's mind.

"Hey. Wanna know pine tree's real name?" The cipher twins' eyes wided. "Wait. You mean dipper is just his nickname?" Will asks disoriented. "Well duh. So shocking that a demon who knows a lots of things doesn't even know a single mortal's real name...." bill drapped his arms behind his neck as his head rested on the headrest of the chair as he smirked.

"Oh this just got interesting! I know dipper's real name!" Mabel stated happily as her heart wanted to scream in excitement. "Mabel! Don't tell them!" Dipper said. Bill chuckled a bit. "Too late pine tree.... it's sorta like weird of the weird... dopper roderick pines? I think.... never knew the truth.... yours is kinda confusing.... plus shooting star's real name and pine tree's has a similarity! But i'm so not gonna tell ya! Welp! I'm gonna get a soda!" Bill left stumbling as he walked to the kitchen. The others looked at him in an disoriented way.

"You guys' names are nicknames?! Why didn't you tell us that dipper and mabel were nicknames?! Mabel. What's your real name?" Will asks. "Well i'm out of here!" Mabel said then walked away.

"So..... dopper roderick pines i believe? How is that you got your name as dipper?" (Y/n) asks drapping her hands on the table. "Because of this...." dipper lifted up his hair then revealed a birth mark of the big dipper.

"Woah. Cool birthmark...." (y/n) stated as she ate a nacho. "Wait. Really? You don't think it's stupid or dumb?" Dipper asks as he puts down his bangs as it covered his birthmark. "Yeah. Why? At least you don't have a birthmark that can move...." will stated as he lifted his bangs up revealing a closed eye like bill's. It opened as it was glowing blue. "Man. That's creepy...." dipper stated.

Will chuckled as he puts his bangs down. "Yeah i know right? I've born with it. It allows me to see everything and everyone is the whole universe because of this eye...."

"But how about (y/n) and Bill?" Bill appeared then drapped his arms on the cipher twins's shoulders. "Well that's the power of cross-dimensional awareness kid! It allows me to see and hear everything and everyone without even seeing or hearing it in person...." bill grinned widely.

"So who wants to go on a mystery hunt?" Mabel asks coming in. "Sure. Wouldn't mind to see every monster in gravity falls again...." (y/n) answered. Dipper sighed in sadness."I wish i have my body back...." bill laughed like psychopath. "Well wish all ya want kid! Cause this body is mine!" He spoke. "Umm...., let's go...." will spoke removing his father's arms away from his shoulder.

They all headed to the forest. "Woah. The forest is beyond big that the last time i saw it inside my mind!" Bill said in cheerfully. "So which monster are we gonna pick?" Mabel asked. "We'll see about that!" Bill pulled put journal 3. He was about to open it but (y/n) grabbed it by flicking her finger as the book magicly approached her hand. "Nuh-uh. If you're planning to destroy the journal so that ford or the pines family can't stop you. Then forget about it. Cause i'll be holdin' this book until dipper gets his body back....." (y/n) says with the book on her hand.

"Fine. Then you wouldn't mind if i destroy the other journals eh? Eh?" Bill nudges his shoulder at his son's elbow. His son frowned."nope. Sorry dad. But i'm in the good side...."

Bill groaned in despair. "Is any relative of mine was actually always evil?!"

"Nah. We're not evil but we still have that psychopatic, blasphemous and masochistic thing that you have....." (y/n) says crossed her arms with the book on her chest.

"Hey. I'm bill cipher....., it's my way.... i'm creature number 326 in journal 2...., fine... name another demon who's as insane, childish, sadistic, mysteriously demeanor and annoying as me?"

"Well he is right with that. No demon is like bill.... they're all short-tempered and simply evil...., bill's a lot evil than the others.... and plus we're not that insane and we're not annoying...." will says. Mabel groaned in despair. "Come on guys! Don't blabber yourself like what bill always does!"

"Hey! I don't blabber!" Bill yelled."Yes you do! You keep on saying that you have omnipotent powers and always says that you're so cunning than anyone in the universe.... plus you think you're so great!!!"

"Well that was the least clever thing that mabel always says...." dipper said beside (y/n). "Don't toy with me shooting star! You don't know what i'm capable of!!!"

"You know you sound a lot like jeff the gnome...." mabel says. "Seriously? So you think arguing is just one of your weird games?" Bill argued.

"Well you think that concering the universe is just one of your stupid games! You're childish plays are so over the top little man!!!" Mabel yelled.

Bill chuckled a bit. "Little? Little man? Try looking at the mirror you preposterous dumb worthless life form!!!"

"Woah. Stop!!! You're arguing will disturb the forest!!" Will yelled cutting in the arguing as he sensed that the forest was getting upset. He can talk to nature's organsims. "Well i'm sorry if the forest doesn't like our yelling!" Mabel yelled. They started arguing.

Dipper shrugged as he scoffed entertained. "Well so much for helping the two stop arguing....." Dipper heard a bellow between the trees as he turned to (y/n) who was reading the journal. She really got an interest with the description of every being inside the journal. "(y/n)! (y/n)! There's something on the bush!" Dipper said infront of (y/n). (y/n) tilted her head up. She looked behind then she saw a giant pair of glowing red eyes. "Is that..... what i think it is....?" Dipper asks staring at the eyes. "Yep. You got the hint. Red glowing eyes. Near a dark spot.... it's a monstrous beast...."

"We should run right?" Dipper asks still looking at the pair of red eyes. "No. Don't move. The beast will only get even more angry if we move...." the beast roared as it's breath reached the two beings faces. (y/n) pinched her nose. "Man. Two words beastie! Breath mints!" The beast roared in anger.

"I think you just made it angry....." dipper winced as (y/n) removed her hands away from her nose.

"You think?!" The two began slowly backing away. "You chose (y/n). Stay here or run?" The beast left the trees revealing it's white scales. And snake body. "Just to say to you dipper. It's a venomous viper.... one of the dangerous creatures...."

"And what do we do right now?"

"Run. Definetly run." They grabbed their friends. They dragged them away from the giant snake. They runned as the white cobra with glowing red eyes crawled behind. (y/n) recodnized bill getting tired. He was sweaty. He fell down. (y/n) towards him as she helped him up. "I can't move these noddle legs!"

(y/n) slapped his right cheek. "Oww! I thought we agreed that you'll never do that!" (Y/n) slapped his cheek once again. "Well i'm not stopping! Move! Move!"

"I can't! This stupid noodle legs won't let me!" (Y/n) slapper bill's cheek."SHUT UP AND BE A MAN!" (Y/n) yelled. "Why are you yelling if you're right beside me?" Bill asks caressing his painful cheeks. Bill's cheeks got slapped again. "SNAP IT TRIANGLE BOY!!!! ARE YOU A CIPHER OR ARE YOU A WIMP?!!?!?!?!?"

"WHY ARE YOU SHOUTING REALLY REALLY LOUD?!!?!" Bill yelled. "IT'S BECAUSE THE VENOMOUS VIPER IS RIGHT BEHIND US!!!"

Right now. The giant snake was behind them. The two looked at the snake's jaw in a suprised way. They don't feel fear because they're demons. Bill can't use his powers and (y/n)'s not powerful enough to defeat this thing.

It was about to bite either (y/n) or bill but it suddenly shrunk as it turned into a baby. It was a size of an worm. They turned to behind them to see will holding his watch which was glowing blue. "Woah. So that's what this watch can do....." will spoke looking at the watch as bill smirked and chuckled a bit."Ah my old pocket watch.... that can whether stop time or turn a being into it's old age or younger age or possibly any age.... kinda missed that watch.... but you can keep it...."

Will shoved his pocket watch on his pocket then lifted the little snake up then placed it inside a jar that he just made by the power of illusion manipulation. (y/n) and Bill stood up then approached the others. "So what are we gonna do with it?" Mabel questions. "I'd say. I'm gonna observe and add some details about it in the journal..... once i get my body back...." dipper says.

Bill saw the sun sunk down as it was now night. Bill smiled normally for the very first time. "Well you can have your dumb body back!" Bill flew out of the body as dipper got forcefully sucked inside the body. Bill revealed on his human form. Floating above the ground."Wait. All this time? You can get out of my body?!" Dipper asked. "Well duh. Powerful demon pine tree.... i just wanted to be a regular human body for a day.... and i lied about that three weeks thing.... you could've thought that through...."

"So wait. You did all of this. Just to be a human boy for a day??" Will asked confused. "Yeah. Just wanted to feel what it's like to be the old bill cipher who was still a human back then...." bill mumbled under his breathe. Unfortunately will, mabel and (y/n) head what he said.

"Wait. Wait. Wait. You were a human back then?" Mabel asks. "Okay i'll spill the beans! I was sad!" bill says crossing his arms. "Woah. Bill cipher? Has feelings? And i thought you were all heartless....." (y/n) teases smirking.

"Hey. I'm still the original bill cipher! I just m-missed what it feels like to be a original or normal or average human! Yeesh. You people don't get it!"

"So you're happy that you finally knew what it felt like?" Dipper asks smiling.

"Yeah. You're right.... dipper..." bill says which led them to shock. Bill never calls dipper his name. Just pine tree or meatsack. And bill never tells that someone was right.

Their jaws dropped. "Why? I just called pine tree dipper for the very first time.... how is that suprising? And.... umm.... sorry or something...." bill mumbled on the last part.

"What was that?" Will teases. "I said. Sorry. Sorry for being rude to you and all. But we're still enemies and also..... thanks for helping me what it feels like to be an ordinary boy! As in run along. Dealing with monsters and stuff....." their jaws dropped one again leaving bill really disoriented. He but his lip.

"Okay.... awkward situation.... A darkness approaches. A day will come in the future where everything you care about will change... Until then I'll be watching you! I'll be watching you... so bye ya!" Bill disappeared in a flash.

"Did he just said that everything we care about will change?" Dipper asks."That's probably what he meant when the rift gets destroyed..... everything will change and the day of the end will come...." will says with glowing blue eyes.

Dipper winces. Will chuckled. "Sorry. But seriously it's true....." will says as his eyes turned back to normal.

"D-did bill just apoligized and thanked us?" Dipepr asks. "Yeah he did.. guess even though a demon like bill.... needed some life as an ordinary boy..... in reality...." (y/n) spoke as they walked away from the forest.

They got to the shack as they made their way to the door."So is your dad really evil?" Mabel asks confused (y/n). "Yeah. He justs misses his body. I mean he hasn't had his body for trillion....."

"Wait. Trillion? I thought it was thousands?"

"Yeah might have dodged a bullet there.... i lied.... so taht you weren't gonna be that shock.... you see will and i are a thousand and sixteen.... bill's a trillion something..... i never knew his birthday.... never even asked in my entire existence...." (y/n) answers. "Wait. Trillion?"

"Yeah. Bill is older than the Universe. In fact, he is older than time itself, as he is at least 1 trillion years old. Why?"

"I mean--- older than time? Is that even possible?" Dipper stated cuts in.

"His exact age is unknown, although Ford describes him as "older than your galaxy, and just as twisted" (y/n) says.

Mabel nodded as she went inside the shack.

Will gave dipper the jar that the little snake in it. "Hey. Dipper.... here's the jar.... have fun with it...." what will called dipper leaved them to a shock. "Oh so now even though my voice is familiar with bill, i look just like bill, i act like bill, doesn't mean i'm bill...., i just called ya dipper okay?! Now i know how my dad feels!" Will stormed inside the shack.

Dipper turned to (y/n). "Umm..... (y/n)? Can i have my journal back?"

"Oh. Sorry forgot about this thing." (Y/n) gave the journal back to dipper as dipper said thank you. "Oh dipper. I forgot to tell you how to summon bill...."

"What?! Why would i even wanna know how to summon that demon?"

"Hey you wanna know that secret or not?"

"Oh fine."

"I'll write it in a paper. Can't say it out loud or else he'll seriously appear!"

"Alright." Dipper stated. He gave (y/n) the journal. she wrote it on the journal. Dipper readed it inside his mind. "Triangulum, entangulum. Meteforis dominus ventium. Meteforis venetisarium!" Translation: Your eyes will glow blue. The sky will turn grey as you enter the mindscape. You'll say "backwards message" backwards 5 times (Asetnoheptus Asetnoheptus Asetnoheptus Asetnoheptus Asetnoheptus).

"Woah. Didn't know even summoning bill would have a meaning. Well i'll try to erase that on my memory!" Dipper says then walked inside the shack. (Y/n) giggled. MY TIME HAS COME TO BURN I INVOKE THE ANCIENT POWER THAT I MAY RETURN"

She turned her head side to side. Then saw no one. What was that? A sign in the future?

She opened a portal to her room then entered it. Behind a pine tree. Reveals bill spying on his daughter. "Well humans emotions. Gotta tell ya. It feels weird. But i like feeling those emotions when i'm inside pine tree's body!" Then he disappeared grinning widely as a flash of wind appeared.
