A blue pulsing light glows. Then, a shot of the vending machine inside the Shack, which is also periodically back-lit by the pulsing blue light. Stan pulls a lever, and green fluid pumps into large, glass tanks.

"Come on, come on. Should be just enough to finish the job." Stan removes his fez and glove, and without knowing, wipes toxic waste on his forehead, which sizzles and briefly glows green, "Whew. Can't be too careful with this stuff."

Red lights flash and a buzzer goes off. Stan smiles and turns to look at screen. The screen reads "EVENT INITIALIZED" and an eighteen hour countdown begins.

Stan, reading from Journal 1, "Warning," blah blah blah, "Extreme usage could result in minor gravity anomalies." Can it, Poindexter!" He slams the journal shut, "I've come this far. I'm not givin' up now!" He pushes a button, and the portal begins to spin, "Yes, this is it."

Stan's fez floats off of his head. Outside the Shack, rocks float off the ground, along with Gompers the goat. A boat lifts out of the lake. In the scrapyard, broken-down cars and junk lift off the ground, and inside McGucket's makeshift shack, a blue light blinks, illuminating the sleeping and floating McGucket and the functioning laptop which now reads "ACTIVE" under an image of the portal. Back in the Shack, Dipper and Mabel, as well as Waddles, float off their beds, but sleep undisturbed. There is a resounding "thunk" as everything in town touches back down to the ground.

"It's gonna be a bumpy ride, but it'll all be worth it." Stan synchronizes what looks like a large wristwatch with the steadily ticking countdown, still displayed on the monitor, "Just eighteen more hours. Finally, everything changes. Today."

A draft blows the journal shut.

Mabel is running down the halls, followed by a tired Dipper.

Mabel, running down hall, "Ahh! It's here it's here it's here!"

Dipper sighs.

Mabel smiled, "Okay, so I was just opening random doors - because I'm a creep - when I found something amazing!"

Dipper, while rubbing his eyes, "If it was worth waking up at seven AM for, that will be amazing."

Mabel smiled, "Feast your eyes!" She opens the door to reveal closet filled with various types of fireworks in a box labeled "DO NOT TOUCH!" She puts her hand on Dipper's shoulder,

Bro. Bro. We're both thinking it."

Dipper and Mabel cheer, "Crazy rooftop fireworks party!"

Stan marches up to them, followed by Will, "Not so fast, kids! There is no way on earth you're setting off those dangerous, illegal fireworks..." He smiles and bends down to put his arms around their shoulders, "...without me."

Dipper is grabbing a icy-pop from the cooler. Mabel is standing excitedly next to Stan, who is sitting on the lounge chair with a lit sparkler and Roman candle. Will just stands on Stan's other side, looking at the sky.

"Here you go, sweetie." He lights Mabel's skyrocket with a sparkler, "Set something on fire for your Grunkle Stan."

Mabel , aiming the skyrocket, screaming, "I AM THE GOD OF DESTRUCTION!" Skyrocket shoots off.

Sheriff Blubs and Deputy Durland approach the Mystery Shack as the fireworks go off.

"Hold on a minute. Do you have a permit for those?" Bulbs asked.

Dipper frowned, "Uh..."

"Uh, do you have a permit for being totally lame?" He and the twins laugh.

Mabel smiled, "Heyoooo!"

Blubs chuckles, "Well, I can't argue with that." Walking away and waving, "Carry on."

Stan laughs, "But seriously though we should probably clean this mess up."

"...With water balloons?" Mabel asked.

Stan shrugged, "I don't see why not."

Stan is sitting outside on the couch drinking a Pitt Cola, and Dipper running away from Mabel, who is throwing water balloons at him.

Dipper laughs, as he runs. Throws water balloon which goes about a foot before falling onto the ground, "Seriously?"

Mabel hits him with a water balloon, knocking him back. Runs by, screaming in a tribal-like fashion.

Stan sighed, "Ah. This is what Saturdays are for. Doing dumb things forever."

Dipper and Mabel, as they jump onto the pile of water balloons, "DUMB THINGS FOREVER!" They land on the water balloons which all pop into a big burst of water.

Stan, as a splash of water comes at him, "Whoa, there!" He laughed.

Mabel, holding up an icy-pop, "To Grunkle Stan! Not just a great uncle...-" "-The greatest uncle!" He and Mabel throw water balloons at Stan.

Stan laughs, "Alright, alright. I tell you it's unnatural for siblings to get along as well as you do."

Mabel waves hand dismissively, "Ha-ha! Don't worry. We've still got plenty of summer left," attacks Dipper in a hug, "to drive each other crazy!"

Dipper pushes Mabel away with a water balloon, which falls on her face.

Stan laughs nervously and frowns, "Yeah, plenty of summer left..." Rubbing the back of his head nervously as Dipper and Mabel approach him, "Kids, there's something I, uh, something I should tell you. It's um," Scratches chin, "Well it's complicated. I... I'm gonna go refresh my soda." Walks away. "Enjoy it while you can, Stan. They'll find out sooner or later. Today's the day."

A glowing red dot appears on Stan's fez.

"What is that, a ladybug? Stan asked, before slapping it. More red dots target Stan, "What the-? Oh no!"

A masked agent pins Stan down. Agent Trigger approaches.

Agent Trigger, into walkie-talkie, "Target secure! Take the house!"

Several helicopters fly above the Shack.

Dipper, Mabel, and Will are surrounded by a handful of agents.

Mabel frowned, "What the-?"

Dipper gasped.

Agent, into walkie-talkie, "Kids are secure. Roof team! Go!"

Several agents rappel out of a helicopter. Cut to the Mystery Shack attic, where agents crash in and cock their weapons.

Agent 2, "Clear!"

Another couple agents rush through the gift shop, wielding a bat. Another crashes through a window, using a rope.

Agent 3, "Clear!"

Yet another agent breaks through Dipper and Mabel's window. Waddles is seen standing in confusion. He squeals when the agent tackles him.

Agent 4, "Pig secure! We have secured a pig!"

The agents wrap yellow police caution-tape around the Shack. Several police cars are parked outside. An agent leads a struggling Stan in handcuffs.

Stan, being led to the government vehicle, "Ugh! Hey, hands off, you stooge!"

Agent plants Stan's face on the trunk of the police car.

"Aah! I don't understand! What did I do that warrants this much arresting?" Stan asked.

Dipper, Mabel, Will, Agent Powers, and Agent Trigger walk up.

Dipper frowned, "The government guys? I thought you died!"

"We survived. Barely," Trigger sighed.

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

"What? Hey! Not in front of the special-ops guys!" Trigger whispered.

Powers, holds up digital tablet, "This is security footage of a government waste facility." pans in on screen where footage of a person in a radiation suit stealing barrels is shown as Powers continues to talk, "At o'four hundred hours last night someone robbed three hundred gallons of dangerous waste."

"What? You think that's me?" Stan asked.

Powers glared at him, "Don't play dumb with us, Pines."

"But I actually am dumb!" Stan shouts as he is led away by an agent, "Last night I was stocking the gift shop. I swear!"

Mabel frowned, "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!"

Powers, bending down to get at eye-level with the twins, "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!" To Trigger, handing him the tablet, "Trigger, you take the children. I'll talk to the old man." To the twins, "Sorry to break it to you kids" Puts on sunglasses, "but you don't know your uncle at all." He walks away.

Trigger snaps his fingers and points at the children. Two agents approach the twins.

Agent 5, bends down and takes Mabel's icy-pop, holding an evidence bag, "Icy-pop. Clear."

Mabel , reaching up toward her icy-pop, "Hey!"

The other agent leads the twins away. Once they are gone the first agent who took Mabel's icy-pop looks to his left to see if the coast is clear and then licks the icy-pop. Mabel and Dipper are led into a police car, and the door is shut behind them. Looking out the window they can see Stan in a government vehicle.

Stan looks at them and taps on the window with his cuffed hands, "Kids, you gotta believe me! For once I'm actually innocent! Kids!"

Wendy, walking towards the Mystery Shack; In a sing-song voice, "Headin' into work. Doo-doo-doo-doo-doooo."

Agent 6, "Ground team! Move, move, move!"

Agent 7, "Break down the door!"

Two agents break down door to the Mystery Shack and a helicopter flies over the Shack.

Wendy turns around and starts walking away, "...Or maybe not."

Stan is getting his mug shots taken, his prints taken, and then Stan sitting in front of a bulletin board with various pictures attached to strings that all meet up to a picture of him.

"Stanford Pines, you stand accused of theft of government waste, conspiracy, and possession of illegal weapons. How do you plead to these charges?" Powers asked.

Stan starts to panic, "Uh, guilti-cent! I mean, inno-guilty! Um, can I have my phone call?"

There is fast food restaurant called "Yumberjacks," where Soos is at the drive-thru.

Soos frowned, "Okay, gimme whatever you got that comes with a free toy."

Stan, through walkie-talky, "Soos!"

Soos, "Mr. Pines?," touches drive-thru lumberjack-speaker, "Is this some sort of... possession situation?"

Stan, through walkie-talky, "Just pick up!"

Soos, picks up walkie-talky, "Mr. Pines, what happened? I heard you got arrested or something? I had to go get some panic food."

Stan, through walkie-talky, "Listen, I need something from you. You know that vending machine in the gift shop? I need you to guard it with your life. No matter what happens, no matter who talks to you, don't let them touch that machine." Walky-talky makes whining sound as Stan cuts out.

"Time for a repair guy," Soos adjusts his hat, "to become a repair man."

Drive-thru employee, sticks arm out to hand Soos his kid's meal, "Sir, your Junior Yum-Yum Baby-Time Kiddo Meal?"

"Just put one in my mouth." Employee opens box, removes a fry, and places it in Soos' mouth. Soos makes munching noises as he chews, "Let's do this."

Tires screech, Soos drives wildly through a hedge.

Dipper, Will, and Mabel are in the car with Trigger.

Powers speaks through a video link at the front of the vehicle, "We've got Mr. Pines in custody. Our men are searching the shack for the device. You take care of those kids."

Mabel gasps, "What're you gonna do to us?"

"We'll be taking you to child services," Trigger informs them.

Mabel frowned, "Boo!"

"In the meantime," Trigger presses buttons, "enjoy some mindless reality TV, designed to pacify you and make you stop asking questions."

Mabel frowned, "Dipper, this is crazy. There's no way Stan was stealing hazardous waste! We gotta clear his name!"

Dipper, thinks, then spots the camera at the front of the car, "Hmm...wait a minute, the security tapes! Didn't Stan say he was restocking the gift shop last night? If we could get the Mystery Shack surveillance tapes, we could prove he's innocent!"

"We just need to think of a way out of here. Think, Mabel...," looking out car window, "Think."

Their vehicle comes up beside a logging truck driven by Manly Dan.

Mabel notices a Sev'ral Timez bumper sticker on the back and knocks on the window to get Dan's attention, writing on the foggy car window, "SEVRAL TIMEZ IS OVERRATED"

Manly Dan gasps, "NOOOOO!"

Veers the logging truck into the government vehicle, which goes into a spin and falls off the road into the forest.

"Mayday! Mayday! Agent down!" Everyone screams, and the car crashes into the trees. Trigger gets stuck between the car and a tree branch, and struggles to get free, "Darn branch!"

Mabel laughed, "Haha, yes!" She opens the door, Dipper, Mabel, and Will leave the car.

"Backup! Requesting backup! Ah!"

Dipper pulls the earpiece out of Trigger's ear and crushes it on the ground.

Mabel smiled, "Come on, Dipper. We're gonna go clear our uncle's name."

"Oh, you poor kids. You really think your uncle's innocent? I've seen it all before." Mabel and Will walk away, but Dipper pauses to listen, "False 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 gonna let him scam you, too?"

"You..." Dipper hesitates, "you don't know what you're talking about." He walks away.

"You're gonna regret this!"

Airbag inflates, Trigger cries out, the car's horn beeps.

Dipper, Mabel, and Will hide on the side of the road. Two government vehicles pass by, and as they do, Dipper, Mabel, and Will disappear from the roadside. The camera angle changes to show them hiding in the trunk of the rear car, and an arrow-shaped sign pointing in the direction they're headed that reads "MYSTERY SHACK".

The countdown now reads roughly five hours. Stan is in the interrogation room, checking his wristwatch device.

"Only five more hours till it happens. I gotta be there! Come on, Stan, you gotta think of a way outta this," he pounds his head on table, "Think! Think!"

Suddenly the device blinks, reading "ANOMALY IN PROGRESS." The coffee on the table floats out of its cup, along with the cup itself and various items, then crashes back down.

"They're getting stronger. Of course, that's it!"

In the center of town, where many cars, objects, and people float off the ground and then fall back suddenly.

The laptop shows the countdown that Stan initiated. McGucket is in his shack, packing a bag, "It's happening! The End Times! When that machine activates... I gotta get outta town!" Shoving a raccoon into a bag, "Get in there, raccoon wife! Git!" Runs off while a helicopter flies past overhead.

Cut to overhead view of the Mystery Shack, surrounded by agents. Dipper and Mabel are hiding in a bush near the Shack.

Mabel smiled, "Alright, here's the plan. I'll take out those two guard guys, you karate chop the other dude in the neck and then we'll back flip through the front door!"

Dipper sighed, "Mabel, aren't you forgetting the simpler solution?"

"Oh, right."

Two agents are looking at the Rock that looks like a face rock.

Agent, "So is it a rock, or is it a face?"

Agent 2, "I think, it's... a metaphor."

As they ponder, Mabel's grappling hook shoots overhead through the Shack's, now broken, window. Dipper, Mabel, and Will slide along the rope into the Shack. They dash down the stairs, avoiding detection from the agents inside the Shack, and head into Stan's office, locking the door behind them. Then the twins fist bump.

Dipper smiled, "Alright. If I was Stan, where would I hide those surveillance tapes?" He looks on the bookshelf and in a filing cabinet)

Mabel , seeing a bolt on the Jackalope head mounted on wall, "Wait! The antelabbit!"

"Don't you mean "jackalope"?" Will asked.

Mabel laughed, "Pfft, that can't be right." She fixed the jackalope's bent antler, and the wall turns open to reveal two old-looking TV monitors and a tape player.

Dipper and Mabel cheer, "Yes!"

Dipper smiled, "Ha! There it is! Stan restocking like he said! And the date shows it was last night! It's proof! He's innocent!"

On the tape, Stan sneaks out of the shop at around 7PM.

Dipper fast forwards through till 8PM, seeing that Stan has not returned, "...Uhh-oh."

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

Cut back to surveillance tape. At 5AM, a figure in a haz-mat suit is wheeling barrels of radioactive waste into the gift shop.

Dipper frowned, "Oh no, Stan, you didn't..."

"Don't panic. That could be anyone in that suit!" Mabel grinned.

Stan, on the tape, drops a barrel on his foot, "Gah! Hot Belgian waffles! Wait, I'm alone. I can swear for real!" He takes a deep breath, "SON OF A-"

Dipper shuts off the tape as Mabel covers her ears, "That's him, alright."

Mabel sighed, "Okay, okay, so maybe Grunkle Stan stole some toxic waste. That doesn't mean he's leading a nefarious double life!"

Dipper pulls a box from under the TV screen, "Mabel, I'm not so sure about that..." He takes a lamp from the desk and turns it on, revealing a box full of passports and IDs.

Mabel , She and Dipper looking through the box, "What? What is all this?" Reading from one of the IDs, "Stetson Pinefield"?"

Dipper, Reading from IDs, " "Hal Forrester?" "Andrew '8-Ball' Alcatraz?" These are fake IDs, Mabel! You wouldn't need these unless you were trying to hide your real identity!"

Mabel frowned, "But why would Stan do that?" She picks a newspaper clipping out of the box, whose headline reads, "STAN PINES DEAD." She passes the clipping to Dipper.

Dipper yelps, "WHAT?! "Stan Pines Dead?" "

Mabel, Reading from article clipping, " "Foul play suspected in Pines' death." Fiery car crash, brakes cut...by who?!"

Dipper picks out another clipping that shows a picture of Stan, " "Unnamed grifter at large?" Why would they call him unnamed? Unless Stan..."

Mabel frowned, "Isn't..."

"Stan?!" The Twins look up at the portrait of Stan on the wall behind them.

The countdown clock, now reads under sixteen minutes.

Dipper paces, "Stan Pines is dead?! Then who have we been living with? It doesn't make any sense!"

"There has to be some explanation," Mabel smiled.

Dipper sighed, "I can't believe it. This whole summer I've been looking for answers and the biggest mystery was right under our nose."

Mabel digs through clippings, "Ugh, there's gotta be some kind of explanation in here somewhere. What the... "secret code to hideout?"

"Let me see that." Dipper takes out Journal 3 and his portable black light, "A1, B, C3"... I've never seen a code like this."

Mabel gasped, "Wait! I have! Dipper, it's the vending machine!"

Stan checks the wristwatch device, which reads about thirteen minutes now.

Powers, enters interrogation room with two other agents, "Alright, Pines. Playtime is over. Chopper's ready to dust off to Washington. I'll enjoy putting you away."

"What? Um, can't we stick around for maybe one minute? Uh, one minute thirty seconds?" Stan asked.

Powers frowned, "We're not falling for your games, Pines. You've been running your whole life. Your time is finally up."

Stan looks at a clock on the wall, "Bathroom break? Just give me... fifteen seconds!"

Powers, as he unlocks Stan's handcuffs, "Sorry, but you've got a flight to catch."

Stan's watch begins to beep; he grins, "Oh, yeah? So do you."

"Huh?"

Everything floats up from the floor. Stan kicks the table into the agents.

"Whoa-whoa-whoa, hey! Aah!"

Stan hits Powers with the back of his chair, turns over, thrusts away from the wall, catches the cuff key in his hands and un-cuffs himself.

"Hey! Dang it, get back here! Men, get him!"

Stan kicks one of the agents in the chest, catches his wallet and hops from agent to agent out of the room.

"No! You won't get away with this!"

Stan slams the door in Powers' face, locking it behind him. His watch beeps and gravity is working again. Behind Stan, Durland falls out of a room next door, followed by a blindfolded Blubs, swinging a bat at a piñata, "Gon' getcha, gon' getcha!"

The agents in the interrogation room slide to the floor with a squeaking sound.

"Ow!"

Outside, everything hits the ground again, and Stan runs out of the station to a taxi.

Stan, panting; To taxi driver, "Do you know where the Mystery Shack is?"

"Uh, yeah?"

Stan sighed, "Okay. Here's a hundred bucks. Drive as far away from the Shack as possible, and don't stop when the cops start chasing you!l The driver shrugs and speeds away, while Stan hides behind a wrecked car as the agents come out of the station.

"He's getting away!" Powers sees the taxi, "Obviously, follow that cab!"

Trigger drives up to order the other agents.

Trigger scowled, "Stanford escaped! He's at large! We need to sweep the town!" As agents disperse from the Shack, "Move! Move! Move!"

Soos sneaks in to guard the vending machine, "Alright Soos, remember the plan. Protect the machine, earn Stan's trust, legally get adopted by Stan, change name to Stan Junior."

"Soos?" Dipper asked.

Soos yelps, "Ahh! Oh, kids! Will! Where've you been?"

"What are you doing here?" Dipper asked.

Soos smiled, "Stan gave me a mission to protect this machine! Ha! And I thought I loved snacks."

"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," Dipper ordered.

Mabel nodded, "Yeah, just let us through so we can prove this is all just a big misunderstanding."

"Guys, I know this seems crazy, but I promised Stan I would guard this with my life."

Mabel , Dipper nods at her, "I'm sorry, Soos." She blows a handful of glitter directly into Soos' face, getting it in his eyes.

"Aah! Attack glitter! It's pretty, but it hurts!" Soon shouts.

Dipper and Mabel jump on Soos, "C'mon Soos... c'mon... c'mon... please."

Soos holds them back as they try to get past, "Aww, c'mon, I don't wanna fight you guys! This hurts me more than it hurts you!" As he is getting kicked in the face by Mabel, "Ah! Seriously, it hurts me way more that it hurts you!"

Dipper reaches for the number pad and enters the code. All shout as the vending machine swings forward, shoving them to the floor. All cough, then gasp at the secret passage behind the machine.

Soos, leading the way down the stairs, "It's like something from a video game..."

Mabel smiled, "Or a dream..."

Dipper frowned, "...Or a nightmare."

Stan races back to the Shack. Soos, Dipper & Mabel head down in the elevator. Stan checks the watch.

"I gotta be there when it happens!" Stan runs through the woods, ripping part of his suit on a branch, "Aah!"

Soos, Will, Dipper & Mabel enter Stan's lab. All gasp.

Mabel frowned, "Guys, are we dreaming? Somebody wake me up."

"This can't be real..." Dipper mumbled.

Soos frowned, "I don't understand. Why would Mr. Pines have all this?"

"It's just like that bunker in the woods..." Dipper realized.

Soos asked, "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!" She sees the picture of her and Dipper, picks it up, "It's still Stan, and he loves us. And we love him. Right?"

"It can't be... it's impossible. 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?!" Dipper kicks desk, "Why would he have those journals?!"

"Maybe he's the author," Soos suggested.

Dipper frowned, "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!" He opens each journal to the page with the portal on it, lays them accordingly, and turns on his black light, before gasping.

Mabel is surprised, "Whoa."

Dipper, reading from the journals, "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! It must not fall into the wrong hands. If the clock ever reaches zero, our universe is doomed!"

All look at the countdown clock, now reading one minute, thirty seconds.

Soos starts panicking, "It's the final countdown! Just like they always sung about!"

Dipper flips through journal to a page reading "MANUAL OVERRIDE", "The agents were right! We have to shut it down!" They all enter the portal room, gasp, ground begins to shake, "There! Quick! Turn these, together!" Soos, Dipper, and Mabel turn three keys, a device near the center of the room pops open to reveal a large red button, "That's it! The shutdown switch! This all stops... now!"

Stan screamed, "DON'T TOUCH THAT BUTTON!" He stands in the doorway, panting, "Dipper, just back away." Dipper's hand remains suspended inches over the button, "Please don't press that shutdown button, you gotta trust me."

"And I should trust you why?! After you stole radioactive waste? After you lied to us all summer?! I don't even know who you are!" Dipper shouted.

Stan sighed, "Look, I know this all seems nuts, but I need that machine to stay on! If you'd just let me explain-" Wrist device beeps, ground begins to shake again, "Uh-oh, oh, no! Brace yourselves!"

They are lifted off the ground and float toward the machine. All over town, things are lifted high off the ground. Gompers "baaa"s. Powers screams as his car flies into the air. Lazy Susan is lifted off her feet in a store. Bud Gleeful grabs onto one of his cars as he and his customers float into the air. The sky darkens and the sun appears red over Gravity Falls.

Computer, "T minus thirty-five seconds."

Stan, spinning in mid-air, "Wh-whoa-aaaah!"

"Aaah!" Dipper screams, before hitting a wooden support, grabbing on to it.

"Dipper!" Mabel shouts. Her ankle is hooked onto a wire over the stand the button is on.

Dipper shouted, "Mabel! Hurry! Shut it down!"

Mabel crawls along the wire toward the button.

"No! Mabel, Mabel, wait! Stop! Aah!" Soos knocks him away from Mabel," Soos, what're you doing?!" Stan hits Soos on the head, "I gave you an order!"

"Sorry, Mr. Pines - if that is your real name - but I have a new mission now! Protecting these kids!" Soos shouted.

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

Dipper pushes off from the support beam, hits Stan and Soos, "Go! Mabel, press the red button! Shut it down!"

"No, you can't!" Stan shoves Dipper away, "You gotta trust me!"

"Grunkle Stan," Mabel cries, "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?" Stan asked.

Computer, "T-minus twenty seconds."

All scream as the portal flashes and pushes Dipper, Stan, and Soos against the opposite wall. Mabel prepares to push the button.

"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!" Stan shouted.

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

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

"He's lying! Shut it down NOW!" Dipper shouted.

"Mabel, please!" Stan shouted.

Computer, "Ten. Nine."

Mabel , "looking away and lowering hand to the button, then looks at Stan, "Grunkle Stan..."

Computer, "Six. Five."

Mabel , lifts hand, "I trust you."

She lets go of the stand, floating up.

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

Computer, "One."

Dipper, Stan, Soos, Will, and Mabel all disappear in an explosion of light as all of them scream.

Light engulfs all of Gravity Falls. Then, everything comes down to earth. The portal, now a mess of tangled wires and metal, glows bright blue. A figure emerges from the portal. The blue light fades behind him. He walks forward, placing a six-fingered hand on the cover of the first journal, then picks it up and places it into the inside pocket of a long, dark coat.

"What...? Who is that?" Dipper asked.

Stan gasped, "The author of the journals..."

Ford pulls off his goggles, revealing his face. He looks nearly identical to Stan.

Stan smiled, "...my brother."
