Chapter Text
Dipper Pines was once again reading over the journal for the thousandth time that summer, he had memorized it front to back in normal light and under black light. He had even tried other lights to see if the book had anymore secrets to give up. There was only a few codes that stumped the young boy. No matter how hard he tried he could never figure out the codes. One of these pages was Bill Cipher’s, under the black light a code, it was long and hard to even read. A pained noise spilled out his mouth as he through the journal across his bed, causing it to hit the floor.
“Whats wrong Dip?” His twin chirped from the other side of the room they shared.
“I still haven’t figured out the author and we have two week till we go home.” He flopped on to his back as he spoke kicking his legs out flat on the bed. It was quite in the shake that day, with the summer ending tourist were less abundant.
“Nothing from McGucket?” Mabel questions as she leaves her art project and walks over to her bother.
“Nothing. He says its still all blurry.” The lad sighs covering his face with the brim of his hat. Mabel walks over to the end of the bed to get the journal, as she picks it up she notices a piece of paper had slipped out of the spin slightly.
“Dipper! I found something!” She squeals knowing how this little paper will make Dipper cheer up. Crawling over to her sister Dipper takes the journal and pulls out the paper. On it is a key, leaning back he grabs his dark light to see if there is anything else on the paper. A small message appears.
I have found something out that could change the fate of the world. I have hidden the information all over town in clues. This cipher is the only way of decoding them.
“Mabel this is big!” Dipper jeers.
“I know! Hopefully this leads us to the author.” She danced a little in her spot. Jumping off the bed Dipper walks over to the twins shared desk and pulled out loose leaf. Quickly flipping through the pages to Bill Cipher’s page.
“Mabel can you hold the light for me?” Holding out the black light to his sister, Dipper quickly starts to work on the message the is scribbled all over the pages. It takes the boy twenty minutes to finally having the finished message. “Okay here it is, This demon has been planing something big. As far as I can tell he has been working on this plan for a long time, working things out so that everything falls in to place. I can’t tell what it is though. So that the first part it seems like the second is a clue to the next chunk of information. I have found out more information about his plans, but I will not post them here. I am leaving a clue for me to find it in the future. This clue is hidden outside of the place were the past is shown.” Dipper paused and looked at his twin.
“What’s that supposed to mean?” Mabel questioned.
“The museum.” Quipped Dipper. “It could also be the library, but they also have fiction-“
“To the museum then!” Mabel cheered and ran off out of the room. Dipper quickly grabbed the journal with the key and some paper.
“Mabel get Soos and Wendy!” He called after his twin as he ran out of the room.
“On it!” He could hear her squeal from the first floor. The boy moved quickly down the steps and almost skidded in to a wall as he took a corner to quickly to get in to the shop. Once in the shop he could tell that they were in. The shops hours had been cut down with out as many tourist coming around now so it was perfect for the group to get out and work on this. It took them ten minutes to close up and head out to Soos’ truck.
—————
It was thirty minutes before the group got to the town’s museum. “So it’s outside. Look for anything that might be off.” Dipper told his friends. They split up and made their ways around the building. It was Mabel that found a small hole holding the next chunk of information. Once back together at the truck they moved to a cafe down the street so Dipper could solve it.
This message was easier to read then the one on Bill’s page in the journal. Making it easier for Dipper to figure out and takes less time then before. “I got it!” He interrupted the groups ramble.
“So read it out.” Wendy urges.
After a cough to clear his throat then speaks. “He has been manipulating human history as well as the physical plain to make his plan happen. I still have not yet figured out what this plan is, but as a day ago he has done a small test outside of town. The area is not safe.” Pausing Dipper looks up with some fear. “Okay and this is the clue. The next chunk is so convenient that is hard to believe you could find any real news here.”
“What does that even mean dude?” Soos asked looking over at the paper.
“Okay it has to be some where convenient and you can get news at.” Dipper thought aloud.
“Newspaper stand.” Squeaked Mabel.
“Well whats the oldest Newspaper stand?” Dipper looked up to the two locals.
“Went up in flames last summer.” Wendy commented.
“Dam.” Dipper muttered. “What else?”
“What about a convenient store ham-bones?” Soos added to the discussion.
“Well that would leave one convenient store in town then. All the others are about mine or Soos age.” Wendy said standing up from her chair.
“Okay so we’re going back to a hunted building great.” Dipper grumbled.
“Well at least your in the ghost good grasses.” Quipped Wendy.
—————
Dipper and Mabel stood out front of the old abandoned convenient store, they left their older comrades behind at the truck. It was already getting late with the sun moving towards the horizon. “Okay Mabel we should look where they sold news papers.” Dipper explained as they entered the store. It took them a moment to find the magazine and newspaper display but it took the pair two hours to find the note. It didn’t help that they ended up having to entertain the ghosts for a small amount of time. Once they found it the group went back to the shake due to the ever loosing light.
By the time Dipper had figured out the third message it was eight in the evening. “Dam it!” He spat at the paper in front of him slamming his fist on the dinning room table.
“Whats wrong bro-bro?”
“The last chunk of information is in the first journal. Which is bad, let me read this.” He paused to take a breath. “After some research of the ‘test’ zone I have come to the conclusion that his plan is the blend our world with the Mindscape. This would lead to utter chaos throughout the planet. I am still working on when his plan will come together.” He paused to let the others absorb the information.
“So wait, Bill is going to cause the world to be a world of chaos? We have to stop this!” Mabel stated.
“But how? We don’t have the first journal.” Soos stated, “How are we going to find it?”
“Find what?” Stan Pines shuffled in to the room he had his slippers on and a cup of tea.
“Grunkle Stan. Mabel and I found a key in the spine of the journal.” Dipper holds up the journal to show his family member. “It helped me solve a message that lead us to others and we have but to finish figuring this out we need the first journal.”
“Kid it’s not possible.” Stan stated flatly, he held up his cup to his lips as Dipper added the last piece of information.
“Its about Bill Cipher-“ Stan spit out the hot liquid from his mouth cutting off Dipper.
“Dipper. Do not get in to anything with that demon.” Snapped his uncle.
“Stan you don’t understand Cipher is going to merge our world with the Mindscape!” Wendy protested, this was no longer about some adventure any more this was about the world.
“What!?” Stan dropped his cup in shock, it shattered sending hot liquid every where.
“The last clue says that when it’s going to happen is in the first journal.” Mabel added.
“I’ll be right back.” Stan left the room quickly.
“Okay so how do we find the first journal?” Soos asked picking up a cookie and nibbled at its edges.
“Well I found this one in the woods. The second one was in the possession of Gideon.” Dipper stated, he rubbed circles over his eyes with the heels of his hands. The room fell silent no one even noticed Stan re entering the room till he dropped something on the table in front of Dipper.
“Find out when this is going down.” He stated. Looking up Dipper saw a journal much like his own but with a one on the front.
“Wait- you?” Dipper started off.
“I’ve had it for some time, gave me ideas for the shack and helped me understand aspects of this place.” Stan answered his nephews question before he properly asked it.
“Mabel black light!” He ordered as he already tore in to the book looking for a message written in the code he was looking for. After two hours of looking through the book under normal light, he pulled out the black light. Mabel had fallen asleep some time ago, well Stan was pulling out boxes from different areas of the shack.
“I found it!” Cheered Dipper after another hour of looking. Heads spun towards him, Windy took the black light from Dipper to hold it over the page for him. After small amount of time Dipper was able to break the code in to the message. His faced paled as he read over the message.
“Dipper what is it?” Windy asked from the other side of the table, since she no longer needed to hold the light up for him. When he didm’t respond right away Stan stepped in.
“Dipper what does it say? If your not going to read it then-“
Dipper interrupted Stan “It’s happening… tomorrow” He was barely able to get the last part out. “Tomorrow at noon.” The room fell silent, Mabel awake from her nap walked over to her brother and hugged him tightly.
Wendy was the one who broke the silence. “So how do we stop Bill?”
“What do you mean we? I’m getting Dipper and Mabel out of here tonight!” Stan yelled.
“Grunckle Stan! We are the only people that know this.” Mabel argued.
“Ya and if we don’t stop it, the whole world will be pulled in to chaos. Home, every where. Stan there is no running from this.” Dipper added to his sister’s statement. “We need to do something.”
“If you kids get hurt-“ Stan started but was cut off by Dipper.
“It doesn’t mater if the world gets fused with the Mindscape! Nothing will. We have to try. If we don't it will be our fault for what will happen.” Dipper yelled at his uncle.
“Your right.” Stan sighed. “We are going up the most powerful demon that exists, jest so we’re all clear.” Stan was not happy about this but he understood that it they didn’t do something it was going to get worse.
“Dipper and I have beaten him twice so far.” Mabel stated happily.
“You what?!” Screeched Stan, “I will be talking to you two after all of this about that.” He snapped.
—————
“Alright we have an hour left are we already?” Dipper asked the small group. It had not expand since the night before. They nodded their answer. The plan was for Stan and Soos to distract Bill then for Windy to cause another distraction by trying to injure Bill with entities that harm demons, leaving Dipper and Mabel to stop the spell. “Everyone set your watches.”
60 Minutes
“Lets go.” Over the night they had pinpointed to locations that Bill may cause the spell to start. The first one was struck off earlier that day by the eerie green glow above the second location. The ‘test’ spot as the journals stated.
—————
Bill floated above the ground and watch the sky turn green. “Soon. I have waited so long for this.” If he had a mouth he would be smiling like a small child getting a gift. “It’s going to be great.”
—————
40 minutes
The group reached the spot, they could see Bill watching the sky. They wanted till they had ten minutes left.
—————
20 minutes
Bill started to give off a blue glow, and the sky started to pulse blue out from the eye of the spell above Bill.
—————
15 minutes
Flames spilled away from the demon now being fully engulfed in the blue fire.
—————
10 minutes
Stan and Soos run out and start to distract Bill. It takes them a moment to get the demon’s attention.
—————
7 minutes
Wendy started shooting at Bill with the harmful compounds using a sling shot. This causes the demon to turn red in anger. He lashes out at the teen.
—————
5 minutes
Dipper and Mabel have slipped in position as close as they can get to Bill. They start the counter, it was meant to mess up Bill enough that he couldn’t go through with the spell.
—————
3 minutes
A magical barrier that surrounded Gravity Falls breaks down letting the green-blue pulsing sky to expand.
—————
1 minute
The flames have engulfed the area around Bill the spell has yet to break. With the counter failing Dipper grabs one of the last items that could hurt Bill, a lumps of rock salt with sage tied around it.
“Dipper! Don’t!” Pleaded Mabel.
“The counter isn’t working. If I can get close enough to Bill I’m going to shoot this at his eye. That should break his concentration.” Dipper weakly smiles at his twin, and before she could stop him Dipper runs off towards Bill. Dodging the flames that lick the ground, the boy makes his way to the eye of this storm.
30 seconds
Dipper stands under Bill with a sling shot and the salt. “Hey Bill?” He shouts up at the demon. The demon looks down at him right when he shoots the small projectile.
“Pine-“ A blood curdling scream fills the air and can be heard in New York state, the salt hit him right in the eye. This causes Bill to be caught in a back fire. A massive explosion that causes a pulse of blue flames to cover the entire sky. It quickly cover the earth and then like that it was gone. Mabel, Soos,Wendy, and Stan are thrown back by the sheer force of the explosion.
Bill had no time to spare, the spell had back fired on him because of some kid. But that kid could save his life at this moment. He moved as fast as his broken form could to Dipper and then quickly entered the body.
Dipper’s eyes shot open as his body filled with a burning pain that started in his head and made its way down his body. It was Bill. He was trying to poses the child, and with out pulling out his soul first it gave Dipper a fighting chance of kicking Bill out. The pain became worse the longer the pair fought for control of the same body. They could both tell Dipper was winning in this battle. The body was covered in the blue flames, back was arched and eyes rolled back causing Dipper to black out.
