Gravity Falls- Once More

Answer to The Cowardly Christian's 'Shake Up the Falls' Challenge!

Challenge- give a vision of Dipper and Mabel's future to whoever you want: Dipper, Mabel, Wendy, Pacifica, Stan, Ford, Soos, etc- You can have it sent to them at any time in the series, or have them sent back in time, or do a Peggy Sue! And have them use this knowledge to shatter cannon!

Also Bill Cipher's threat needs to be taken more seriously!(I'm talking actual full-on Armageddon preparation after his first appearance!) And they need to take Gideon seriously when he sends the creepy letters and hosts his TV show(You don't have to kill him, but the Pines Family have to at least Neutralize him...or make some kind preparation to fight him when he breaks out). EXAMPLE: Mable is forced to take Dipper more seriously and not mess with him to survive or The realization that she and her loved one's might die at the end of the summer make Wendy not so hung up on the whole 'age gap' with Dipper and goes out with him.

Also, the hero's need to be proactive! When Gideon starts sending creepy letters and making television broadcasts, they need to take care of him(kill or neutralize; either works). All that matters is that they strike first at the first sign of trouble; And don't just have them wait around and do nothing!

This is my first attempt at both a challenge and a multi-chapter fanfic, so if I make a mistake, please just tell me so I can revise it.

Let's do this!

Prologue

Dipper's world was crashing around him. In the past few hours, government agents and attempted to arrest him, his sister Mabel, and is Grunkle Stan. He and his sister also found Stan's stash of fake IDs and video evidence of Stan stealing radioactive waste. Then, they discovered a large lab hidden behind the snack machine in the Mystery Shack. The top it all off, sitting there on the desk were the other two journals. Dipper began to feel frustrated. How could this have happened? Was anything he knew about his Grunkle real?

"All this time? All this time Stan had them? I can't believe it! Was anything he said to us real? Why would he have those journals?" Dipper cried out in frustration.

"Maybe he was the real author" Soos said trying to justify Stans actions.

"Or maybe he stole them from the author! Maybe the reason he has all this fake IDs is because he is a master criminal and this machine is his master plan!"

Dipper opened all three journals to the page with a mysterious diagram on them. He then placed them together to create one complete diagram of a large machine. Shining his darklight on the pages, he, Mabel, and Soos gasped at the word staring back at them.

"I was wrong the whole time. The machine was meant to create knowledge but it is too powerful! I was deceived, and now, it is too late! the device, if fully operational, could TEAR OUR UNIVERSE APART!"

Dipper cried out in shock as he read the page. The next page showed an image of the world split in half with the words "Total Global Destruction" written underneath it. Dipper continue to read.

"It must not fall into the wrong hands. If the clock ever reaches zero our universe is doomed."

The three of them looked up at the clock, only to see that minute-and-a-half remain on the timer.

"It's the final countdown, just like the one they've always sung about!" Soos cried.

Dipper begin to flip through the book, desperate to find a way to shutdown the machine.

"The agents were right! We have to shut it down!"

The three of them ran into the portal room. The entire lab was shaking violently, and the portal was swirling, a red and orange outline along a white circle. Dipper looked around.

"There, quick" he said as he saw a panel that said manual override. The three of them ran over to a large counter, which held three keys in locks.

"Turn these, together". The three of them turn the keys in synchronisation. Behind them, with a loud hiss, a large ball on a staff opened up, revealing a large, red button that was concealed inside it.

"That's it! The shutdown switch!" The three of them ran to and surrounded the button. It continuously flashed, pulsing with a red light.

"This all… stops… now!" Dipper cried out, as he brought his hand down onto the button; only to be stopped when it's Grunkle Stan ran in.

"DON'T TOUCH THAT BUTTON!" Grunkle Stan screeched, gasping for breath. Dipper, Mabel, and Soos turned around and looked at him. Four of them stood there awkwardly, the tension could be cut with a knife.

"Dipper, just back away" Stan said, holding his hands out in front of him. Dipper looked at the button and then back at Stan. "Please don't press that shutdown button, you gotta trust me".

"And I should trust you, why?" Dipper asked before placing his fingers to his temple. "After you stole radioactive waste? After you lied to us all summer?! I DON'T EVEN KNOW WHO YOU ARE!"

"Look I know this all seem nuts, but I need that machine to stay on. If you just let me explain-" Stan was cut off by the beeping of his wristwatch. "Oh no. Brace yourselves!"

They all began to scream is the portal sped up, and all four of them lifted into the air by a lack of gravity.

"T-minus 35 seconds" an automated voice stated. All four of them were flung about different parts of the room.

"Dipper!" Mabel cried out. Dipper turned around to see Maple floating in the air with a cable wrapped around her foot.

"Mabel, hurry, shut it down!" Dipper cry it out as he pointed towards the button. This madness needed to stop. He didn't know what this machine was doing, but he knew the author said was dangerous and therefore needed to be shut down.

Mabel grab the cable and used it the grapple down to the button.

"No!" Grunkle Stan cried out as he attempted to push himself off the wall towards the button. Mabel reached the button. "Mabel, Mabel, wait, STOP!" Maple turned to her grunkle just in time to see him get tackled by Soos. "Soos, what are you doing? I gave you an order!"

"Sorry Mr. Pines, if that is your name, but I've got a new mission now; protecting these kids!" Soos said, half in anger, half apologetically.

"Soos, you idiot, let me go!"

Dipper launched himself off the wall towards Grunkle Stan and Soos, and together, the two of them attempted to restrained Stan. Dipper then turn towards his twin sister.

"Mabel, press the red button. Shut it down!"

"No, you can't! You gotta trust me!"

Mabel looked conflicted.

"Grunkle Stan! I don't even know if you're my Grunkle!" She cried out tearfully, hugging the pole in despair. Dipper, Soos, and Grunkle Stan stopped fighting as they saw Mabel begin to cry, her tears floating upward in the Anti-gravity. "I wanna believe you, but-"

"Then listen to me" Grunkle Stan interrupted. "Remember this morning when I said I wanted to tell you guys something?"

"T-minus 20 seconds" the automated voice stated. The four of them screamed again as the portal flashed white. Then, Dipper, Soos, and Grunkle Stan were flying against the wall. Mabel barely hung on to the pole. She raise the perfect and was about to bring it down on the button.

"I wanted to say that you were going to hear some bad things about me, and some of them are true, but trust me. Everything I've worked for, everything I care about, it's all been for this family!"

"Mabel, what if he's lying? This thing could destroy the universe! Listen to your head."

"Look into my eyes Mabel. Do you really think I'm a bad guy?"

"Mabel he's lying! Shut it down now!"

Mabel look back and forth between her brother and her Grunkle.

"Mabel, please!" Her Grunkle beseeched as the automated voice begin to countdown the seconds.

Mabel put her hand on the button, and then looked into her Grunkles eyes. "Grunkle Stan" she said, turning her head away, "I trust you." She let herself float away from the button.

Dipper was devastated. Mabel, his twin sister, had shows in the man who may or may not really be their Grunkle over him. The portal was about to activate, potentially going to destroy them all, and she trusted Stan over him.

With a shout of defiance, and strength he didn't know he had, Dipper pushed himself off the wall and flew over towards the button. He reached it, and that's the counter hit "One," he slammed his fist down onto the button.

Now, Dipper had no way of knowing this, this caused your paradox within the portal, wanting to activate and deactivate at the exact same time. The portal glitched, and, to everyone's horror, Dipper was pulled into the portal.

"Dipper!" Mabel's cry of anguish was the last thing he heard before he fell unconscious.

….

A forty-something year old Dipper enters his parents house and takes off his fast-food uniform with a sigh as he looks down at his meager paycheck.

A forty-something Mabel (wearing a crazy sweater and surrounded by dozens of cats); looks up.

"Hey Dipping sauce! Guess what!? I made a 50 ft butterfly made of comics...which I then set ablaze! I'm still the goddess of destruction!...also the police are here again to fine us for burning stuff without a permit...also for unintended arson damage to the neighbors house"

"Wait, what!?" Shouts Dipper just as a policeman steps out of the shadows and snatches up Dipper's paycheck.

"Ah, come on man! I worked overtime the whole week at the drive-through to earn that!" Shouts Dipper. But the Officer had already left.

Dipper feels a drop of water on his head...the ceiling was leaking...

"I also created a new water slide for Waddles!"

CRASH!

The ceiling gives way as a giant hog crashes down and breaks the floor; water soaking everything!

The cats scatter in panic; breaking various household objects as they do so.

Mabel laughs at this. "Ah, they're cute when their crazy!" She shouts as she takes a picture of them.

Dipper sighs as he goes to check the emergency fund...only to find it empty...

"Hey Dipping sauce! Can we have Pizza tonight!? Duck-tective will be on!" Shouts the ever cheerful yet oblivious Mabel.

Dipper just hangs his head...and cries…

….

Dipper gasped for breath is he suddenly sat up. He looked around, only to see that he was on a... bus?

"Rise and shine Dipping-sauce!" Dipper snapped his head to the side to see me both sitting there, in the same sweater she wore on the first day of summer, smiling at him.

"Mabel! What happened! Where are we! Did we deactivate the portal in time! Where's Grunkle Stan!"

Mabel smiled at him, confused. "Dipper, are you alright? Don't you remember? It's the first day of summer, we're on a bus heading to Gravity Falls, where Grunkle Stan is. What portal? Are you sure you're completely awake? Whatever dream you had must have been cray-cray!"

To say Dipper was confused was to say that water was wet. Somehow, instead of being in the lab, attempting to shut down the portal, he was now on the bus heading to Gravity Falls. He must have somehow travelled in time! And that vision… what did it mean?

"Dipper?" Dipper remember that Mabel was still there, and expecting an answer.

"You're right Mabel" Dipper said slowly "it was one crazy dream." Only he knew it wasn't just a dream. He had a second chance at this summer, and he wasn't going to waste it. First, he was going to think of what that vision was, and what it could possibly mean. Then, he was going to figure out everything Grunkle Stan knew, and find out who that man really was.

He seriously needed the think.

Hey guys, TheReaper51303 here, and that's the first chapter of my new story. In this story, I'm going to be fixing many of the things I thought went wrong, or could be improved on, the Dipper is going to be stronger and more independent, less willing to give into his sister, it more willing to treat others as a threat. I haven't completely decided on the pairings, but I'm leaning towards Dipper x Wendy and Tyrone x Pacifica, but that'll come later. Peace out, guys!
