~~~~~~~~~Third Person POV~~~~~~~~~

That morning, Dipper was woken up by a very excited Mabel, who forced him out of bed and dragged out of the room, saying she had a surprise.

It was only around seven in the morning, and he was so tired that his vision was blurry, and was having trouble to not fall asleep, but Mabel's screams did a good job of keeping me awake. "Ahhhhhh!!! It's here it's here it's here!!!"

She finally stopped in front of a door, turning to him with a wide smile. "Okay, so I was just opening random doors because I'm a creep when I found something amazing!!! Feast your eyes!!!" She opened the door, revealing a box filled with fireworks.

Dipper's eyes widened, a smile on his face. "Whoahoho!!!"

"Bro, bro, we're both thinking it!"

"Crazy rooftop fireworks party!!!"

"Not so fast, kids!!!" The two siblings froze as they heard Stan's voice from behind, seeing him glaring down at them. "There is no way on Earth you're setting off those dangerous illegal fireworks. ... without me."

Quickly getting dressed, they headed up to the roof with the fireworks, Stan handing the first one to Mabel. "Here you go, sweetie! Set something on fire for your Grunkle Stan!"

"I AM THE GOD OF DESTRUCTION!!!" She let go of the firework, which explodes in the air, all of them laughing as they stared in awe.

That's when they noticed the sheriff and his deputy walking over with serious expression, Blubbs speaking. "Hold on a minute, do you have a permit for those?!?"

"Uh..."

"Do you have a permit for being totally lame?!?" Stan yelled back, all of them laughing, including the police.

"Well, I can't argue with that! Carry on!" And him and Durland walked away.

Stab then let out a sigh. "Seriously though, we should probably clean this mess up."

Mabel paused for a second. "... With water balloons?"

"I don't see why not."

~~~~~~~~~~~~~~~~~~~~~~~~~~

Dipper was running away laughing, stopping to throw a water balloon which gently landed near him, looking down in disappointment. "Seriously?"

Not even a second passed by when a water balloon hit his face, forcing him back as Mabel yelled in victory. "WOOOOO!!!"

Stan simply leaned back against his seat with a smile. "Ah, this is what Saturday's are for. Doing dumb things forever!"

"Dumb things forever!!!" The twins both jumped into a big pile of water balloons, all laughing as Stan avoided the droplets.

Mabel then raised her popsicle with a smile. "To Grunkle Stan!!! Not just a great uncle!!!"

"The greatest uncle!!!" Dipper finished for her before they both threw a water balloon at him.

With a laugh, he stood up. "Alright, alright, I'll tell ya. It's unnatural for kids to get along as well as you do!"

"Haha, don't worry!!! We just still got plenty of summer left to drive each other crazy!!!" Mabel hugged her brother tightly, who pushed her away and caused a water balloon to land flat on her face.

Dipper: *pushes Mabel away causing a water balloon fall on her*

However, Stan's laugh was more forced this time. "Yeah, plenty of summer left.."

A few moments of silence went buy, when Stan walked closer to the twins. "Kids, there's uh... there's something I should tell you. It's um... well, it's complicated..  I.. ... I'm gonna go refresh my soda."

Dipper and Mabel stared as their great uncle walked to the shack, confused to whatever had just happened.

Before anything else could happen, some fancy black cars started to park near and helicopters started flying above the shack. Men in black armor surrounded the twins, a few tackled Stan, and the rest broke into the house.

One of the men had tied Stan's hands together and pressed him against a car, who struggled to be set free. "Hey, hands off, you stooge!!! I-I don't understand!!! What did I do that warrants this much arresting?!?"

Dipper's eyes widened in realization, recognizing two specific people. "The government guys..?! I thought you got eaten by zombies!!"

"We survived. Barely."

"I used Trigger as a human shield. He cried like a baby."

"Hey!! Not in front of the special ops guys..!!" Trigger shrunk back in embarrassment, Power walking over to Stan with an iPad. "This is security footage of a government waste facility. At o-four hundred hours last night someone robbed three hundred gallons of dangerous waste."

"What?!? You think that's me?!?"

"Don't play dumb with us, Pines."

"But- but I actually am dumb!!! Last night I was restocking the gift shop!!! I swear!!!" Stan tried to argue back.

Mabel quickly yelled at them. "Wait!!! Grunkle Stan!!! You've got the wrong guy!!! Our Grunkle Stan might shoplift the occasional tangerine but he's not some evil super villain!!!"

Power, on the other hand, was more serious than ever. "Listen, kid, we've been watching your family all summer and we've seen some disturbing things. But nothing as dangerous as what your uncle is hiding. Somewhere hidden in this shack is a doomsday device!"

The twins' eyes widened, unable to believe such accusations as the man walked away. "Trigger, you take the children. I'll talk to the old man. Sorry to break it to you, kids, but you don't know your uncle at all."

Trigger snapped his fingers, one of the other man taking Mabel's ice pop. "Icy-Pop, clear!"

"Hey!!"

They were then forced to enter the policemen's car, and watched as Stan was forced to another car, yelling that he was innocent, then was driven away.

As the kids were taken in the car to wherever they were heading, so many questions zoomed through their heads. Stan was innocent, right? There's no way he'd do such a thing!

At the moment, Trigger had called power in the car's computer, who was explaining the situation. "We've got Mr. Pines in custody. Our men are searching the shack for that device. You take care of those kids."

Mabel let out a gasp. "What are you gonna do to us..?!"

"We'll be taking you to child services." Trigger replied, Mabel booing in response. "In the meantime, enjoy some mindless reality tv designed to pacify you and make you stop asking questions."

Neither of them cared for whatever was on the tv, the worry of the situation was far too big to handle at the moment.

Mabel turned to her brother, eyes wide in fear as she whispered. "Dipper, this is crazy..!! There's no way Stan was stealing hazardous waste, we gotta clear his name..!!"

"Hm..." Dipper looked around, his eyes soon landing on a camera. "Wait a minute, the security tapes! Didn't Stan say he was restocking the gift shop last night? If we can get the Mystery Shack surveillance tapes we could prove his innocent!"

"We just need to thing of a way out of here..!"

As they began to think of a place, they noticed a strange (f/c) glow suddenly surround the car. Trigger looked around in a panic, unsure of what was happening as the car stopped moving.

Right beside them was a tree, which started to glow a dark purple and soon slowly began to fall just as the car's back left door opened, the twins running outside just as the tree fell on top. No serious damage was done, and no one was hurt, but the tree was curved in such a way that stopped Trigger from opening the door.

"You guys okay?!" They both turned around at the sound of (y/n)'s voice, seeing her and Leo running over. Mabel quickly wrapped the two in a hug, smiling brightly. "Wow, you guys are like superheroes!!"

"Back up!!! Requesting backup!!!" Trigger yelled into his air piece, only for Dipper to yank it off and step on it.

Leo raised an eyebrow. "Uh, just what exactly did we miss?!"

"Yeah, when we got to the shack, there were tons of government people!" (y/n) added.

Mabel crossed her arms with a small glare. "We'll explain on the way back. We're gonna go clear our uncle's name!"

The four began to walk away, and Trigger spoke once more. "Oh, you poor kids. You really think your uncle's innocent? I've seen it all before."

Dipper stopped in his tracks, a feeling of nervousness going down his spine.

"Fake names, double lives; one minute they're playing with water balloons the next they're building doomsday devices! Your uncle scammed the whole world, you're gonna let him scam you too?"

"You-" Dipper paused, turning to face the man in the car. "You don't know what you're talking about."

"You're gonna regret this!!!"

~~~~~~~~~~~~~~~~~~~~~~~~~~~~

They were able to make it back to the Mystery Shack and sneak in unnoticed. (y/n) and Leo now had all the information needed to understand what was happening, and were in with the plan to clear Stan's name.

They entered Stan's office and locked the door, beginning the investigation.

Dipper tapped his chin in thought. "Alright, if I were Stan, where would I hide those surveillance tapes?"

"Bingo!" (y/n) snapped her fingers, the antler of the jackalope on the wall turning, and triggering the wall to switch around, many monitors revealed.

Dipper's eyes grew wide. "Whoa! How'd you know?!"

She simply shrugged with a confident smile. "I've worked with Stan for five years now, his tricks are getting old."

Mabel then noticed a tape halfway into the player, pushing it back in. "It's this week, this is it!"

Once it turned on, the tv showed Soos on the floor doing a worm dance as Mabel, Wendy, and (y/n) chanted Go. Dipper raised an eyebrow, Mabel giving a shrug. "Someone yelled wormy dance, we had to!"

They then fast forwarded a few hours, eventually reaching when it showed Stan restocking the gift shop, Dipper smiling at the results. "Hah, there it is! Stan restocking like he said!"

"And the date shows it was last night!" (y/n) added excitedly. "It's proof! He's innocent!"

"Uh, don't get too excited yet.." They both turned to Leo, who pointed at the monitor, which showed Stan leaving the gift shop.

Dipper fast forwarded a few hours, and Stan still hadn't come back, a worrying look over his features. "Uh-oh..."

Mabel forced on a smile. "Uh, maybe he's just going to the bathroom outdoors! The way nature intended!"

"Yeah, for like three hours..?" (y/n) asked as she crossed her arms.

Dipper fast forwarded some more, and finally a man was revealed wearing a completely yellow full-body suit, carrying a bunch of barrels. The four of them let out a gasp, blood growing cold as the worst appeared in front of them.

You, Dipper, and Mabel: *gasp*

"Stan, you didn't..."

"Don't panic!" Mabel quickly interrupted her brother. "That could be anyone in that suit!"

The man then hit his foot against one of the barrels, gripping it in pain. "Hot Belgian waffles!!! Wait, I'm alone! I can swear for real!!! SON OF A-!!!"

Dipper quickly turned it off at that, the four of them staring at the monitor in disbelief as Leo spoke. "Yep, that's him alright..."

"Okay okay, so maybe Grunkle Stan stole some toxic waste! That doesn't mean he's leading a nefarious double life!" Mabel chuckled a bit, but it was obvious she was trying to convince herself more than the others.

(y/n) then picked up a box, placing it on top of Stan's desk as she searched through it. "M, I'm not so sure about that..."

The others surrounded the box, Mabel taking out a few IDs and passports. "What...? What is all this...? Stenson Pinefield...? Hal Forester...?"

"Andrew "8-Ball" Alcatraz..?!" Dipper asked in anger as he pulled out another ID.

Leo took out a few himself. "I'm no expert, but these are definitely fake IDs.."

"And you wouldn't need these unless you were trying to hide your real identity!" Dipper exclaimed, anger obvious in his gaze.

(y/n) placed the IDs she was holding back in the box. "But why would Stan need to do all this..?!"

A gasp was heard, and the three of them turned to see Mabel a few feet away, her back turned to them. Leo was the first to walk over, placing a hand on her shoulder. "Mabel..?"

She didn't speak, and only handed him a newspaper opened on a certain page. He only had to read the title of the article, eyes widening in terror. "What?!?"

Dipper and (y/n) quickly ran over, Dipper reading out loud as their eyes grew wide as well. "Stan Pines dead?!?"

"Foul play suspected in Pines's death, fiery car crash?!? Breaks cut?!? By who?!?" (y/n) continued to read, her voice shaking a little in terror.

Dipper then picked up a small paper from the ground. "Unnamed grifter at large?!"

"Why would they call him unnamed..?" Leo raised an eyebrow.

However, (y/n) was already putting all the pieces together. "G-guys.. what if Stan isn't.."

Dipper's eyes widened even more, understanding what she was trying to say. "Stan.. i-isn't.. Stan?!?"

~~~~~~~~~~~~~~~~~~~~~~~~~~~~

At the moment, Dipper was pacing around the room, trying to figure out what this all meant as the others watched, just as confused and startled. "Stan Pines is dead?!? Then who have we been living with?!? It doesn't make any sense!!!"

(y/n) gently grabbed his wrist to stop him. "PT, you have to calm down, I'm sure there's some explanation for this..!"

Mabel then put on a smile. "Maybe we're getting ker-pranked!!! Justin Kerpranked is gonna jump up from behind one of these plants any minute now!!" She waited a second before going over to a plant and peeked inside. "Any minute, Justin!!!"

"I can't believe it!" Dipper pinched the bridge of his nose. "This whole summer I've been looking for answers and the biggest mystery was right under our nose!!"

Leo hopped off the chair he was sitting at. "There's gotta be some kind of information here somewhere. We just haven't looked hard enough."

(y/n) gave another quick scan around the room, her eyes soon landing on a tiny piece of paper that was under a few books, pulling it out. "What the..? 'The secret code to hideout'..?"

"Let me see that!" Dipper shined the black light over the paper in (y/n)'s hands, reading what was now in view. "I see a 1, C, B, 3, I've never seen a code like this..!"

"Wait, I have!!" Mabel perked up, turning to the others. "Guys, it's the vending machine!!"

And so, they waited until the guards left and went to the vending machine. To their surprise though, Soos was there in front of it as they ran over.

"Soos!!!" Dipper called out as they stopped in front of him.

Soos looked over, smiling at the sight. "Oh, kids!! Where have you been?"

"Wha- What are you doing here?!?"

"Stan gave me a mission to protect this machine! Hah, and I thought I loved snacks!"

(y/n) then began to explain. "Soos, listen, something huge is going on here! If Stan is hiding some dangerous secret, we need to find out what it is! I need you to step aside!"

Mabel's smile was obviously forced as she spoke. "Yeah, just let us through so we can prove that this is all just a big misunderstanding!"

However, Soos wasn't on board of their plan, scratching the back of his neck nervously. "Guys, this seems crazy, but I promised Stan that I'd guard this with my life!"

That's when Leo gave a nod to Mabel, who let out a sigh and took a step forward. "I'm sorry, Soos.." She then blew a handful of glitter on Soos's face, who stumbled back at the pain.

"AH!!! ATTACK GLITTER!!! IT'S PRETTY BUT IT HURTS!!!"

The four of them tries to sneak past, but Soos did a good job of keeping them away. "Aw, c'mon, I don't wanna fight you guys! This hurts me more than it hurts you! Seriously, it hurts me way more than it hurts you!!"

Leo was the one who managed to type in the code into the vending machine, and to everyone's surprise, the vending machine opened with a swing, forcing everyone to fall back.

They coughed at the dust that, eyes growing wide as they saw the opened passageway on the wall. One after the other, they walked into the passage.

A shiver went up Soos's spine at the sight. "It's like something from a video game..!"

Mabel followed behind her boyfriend. "Or a dream..!"

"Or a nightmare.." Dipper was the last to go in.

At the end was an elevator, and although the nerves were too much to bare, they stepped inside and went to wherever it led. It took them deeper into the bottom, into a room filled with many computers, monitors, and strange buttons.

Mabel was the first to break the silence. "Guys, are we dreaming..? Somebody wake me up..!"

"This can't be real.." Dipper muttered to himself, walking forward.

(y/n) followed along, searching for anything in the room with her eyes alone. "Why would Stan have all this..?"

"It's just like that bunker in the woods.." Leo pointed out, the others quickly noticing the similarities between the two places.

Soos fiddled with his fingers. "But what is it doing underneath the Mystery Shack?!?"

"Okay okay, so he's got a huge gigantic lab!! That doesn't mean anything bad..!! Everyone's got secrets!!" Mabel took a picture of her and Dipper. "It's still Stan, and he loves us! And we love him, right..?!"

A gasp was then heard, everyone turning to (y/n), who was staring at the desk in front of her. Dipper quickly ran over, and his eyes grew wide in shock as he saw Journals 1 and 2. "It can't be... It's impossible..!"

"Dipper.." (y/n) quickly tried to calm him down, but it was too later as he took out the third journal.

"The other two journals..?!? 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?!?"

Soos stepped forward, trying to fix the situation. "Maybe he's the author!"

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

Filled with rage, Dipper took the journals and opened them in the pages that showed a different portion of a machine that was at the other side of the glass wall, places them together to reveal one complete machine, then shined the black light on the pages to read.

"I was wrong this 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 is fully operational- Could tear our universe apart!!! It must not fall into the wrong hands, if the clock ever reaches zero our universe is doomed!!!"

1:30 minutes

Soos let out a gasp. "It's the final countdown!!! Just like they always sung about!!!"

"The agents were right, we have to shut it down!!!" Dipper yelled as he desperately searched through the journals, looking for an answer, or anything at all!

1:15 minutes

The five of them ran to the other side of the wall, Dipper's eyes quickly landing on a machine into he side. "There!!! Quick!!!"

They all ran over, turning the four keys that were placed in the machine, a red button coming out of the floor.

"That's it!!! The shutdown switch!!!" Without thinking twice, Dipper ran to the button, a hand raised to push it. "This all stops now!!!"

"DONT TOUCH THAT BUTTON!!!"

The room fell into a complete silence as Stan stood by the doorway, catching his breath after running all the way here. 

Dipper had a sharp glare on his face as Stan tried to walk over, his expression one of shame. "Dipper, just back away..!! Please don't press that shut down button..!! You gotta trust me..!!"

"And I should trust you why?!? After you stole radioactive waste?!? After you lied to us all summer?!?"

"Look, I know this all seems nuts, but I need that machine to stay on!! If you just let me explain-!!"

beep

beep

beep

Stan's eyes quickly widened. "Oh no, brace yourselves!!!"

At his words, everything and everyone began to float around as if there was no gravity. Everyone did their best to hold on with whatever was near, pressed against the walls.

t-minus 35 seconds

"Dipper!!!" Mabel yelled, her foot tangled with a string to keep her in place.

When he noticed how close she was to the button, he yelled. "Mabel, hurry, shut it down!!!"

Mabel looked down, grabbing the string and pulling herself closer to the button.

"NO!!!" Stan yelled, tried to float towards her, yelling for her to stop, only for Soos to tackle him to the side. "Soos, what are you doing?!? I gave you an order!!!"

"I'm sorry, Mr. Pines, if that is your real name, but I have a new mission now: protecting these kids!!!"

"Soos, you idiot, let me go!!!"

"Mabel, hurry!!!" (y/n) yelled at the top of her lungs, followed by Dipper.

"Shut it down!!!"

"No, you can't!!!" Stan yelled back. "You gotta trust me!!!"

There were tears heavily streaming down Mabel's cheeks as she stared at her family. "Grunkle Stan I-... I don't even know if you're my grunkle...!!! I wanna believe you, but-!!!"

"Then listen to me!!! Remember this morning when I said I wanted to tell you guys something?!?"

t-minus 20 seconds

A bright light began to shine from the machine, pushing everyone except for Mabel to the back wall, screaming in terror.

Stan quickly managed to look back at her. "I wanted to say that you're gonna 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 for this family!!!"

"Mabel, what if he's lying?!?" Dipper yelled back, anger burning in his eyes. "This thing could destroy the universe!!! Listen to your head!!!"

"Look into my eyes, Mabel!!! You really think I'm a bad guy?!?"

"He's lying, shut it down NOW!!!"

"Mabel, please!!!"

Mabel stared at her great uncle, her head filled with so many thoughts, and her heard aching worse than she had ever felt before. "Grunkle Stan, I..."

Finally, she made a decision, closing her eyes and letting go.

"I trust you."

"MABEL, ARE YOU CRAZY?!? WE'RE ALL GONNA-!!!"

As the light completely covered the room, the only thing heard for five minutes were the screams of fear from the people who were about to face the unexpected.

However, to let the relief sink in, they were all unharmed, just on the floor as they adjusted to the dim lights once again. Everything in the room was destroyed, including the machine, but the portal was still on and working.

Their eyes widened once again as a strange man took a step into the room from the portal. He had a heavy jacket with a hook on, and large goggles, his face hidden from everyone. He first walked over to journal 1, and placed his six-fingered hand over it before then picking it up and placing it inside his jacket.

Dipper stared in disbelief. "W-what...? Who is that..?"

"The author of the journals.." Stan answered, the strange man taking off his hood and goggles.

"My brother."

Silence fell upon the room, everyone expect Stan staring in pure shock at what just happened in front of them.

Mabel was the one to break the silence. "Is this the part where one of us faints?"

Soos let out a chuckle. "I am so on it, dudes." And fell back.
