(Dark clouds rise above sat at a table refereeing a football game between the Tame Gamers (Stan, Ford & Soos) and the Disaster gangs (Wendy,Dipper & Mabel)

Old Man McGucket :The score is 28-28. Next touchdown wins! But who's gonna take it home? The Tame Gamers or the Disaster gangs?

(A storm begins with the clap of thunder and rain pours down on the guys)

Soos:Oh, dude! It's raining!

Ford:Well, I guess that's that. Let's go inside.

(Everybody except Dipper and Mabel retreat to the shack)

Mabel:Oh, so I guess you forfeit?

Stan:And risk getting struck by lightning? Yes, we forfeit.

Mabel:Oh, come on. People don't actually get struck by lightning. That's just an old wives' tale.

Dipper:Yeah,(laughs)Yeah, we got a bunch of old wives over here!(laughs)

(Wendy, Soos and Old Man McGucket take cover in the porch of the shack, while Stan and Ford stay behind to challenge Dipper and Mabel)

Stan:Oh, it's on.

(Stan and Ford walk over to the football. Stan grabs the ball between his legs)

Stan:Hut, hut! Hike!

(Ford hikes the ball to Stan, who backs up and throws it to Stan, who is running ahead)

Ford:I got it! I got it!

(Mabel jumps in the way of the ball and grabs it, running in the opposite direction. She laughs, but is then tackled by Stan, throwing the ball to Dipper. Wendy, Soos and Old Man McGucket gasp, as Dipper brings his arms out to catch the ball)

Dipper:I got it! I got it!

(Dipper catches the ball)

Dipper:Yes!

(Dipper downs the ball on the goal line, winning the game)

Mabel:Whoo! Whoo! Yes!

(Mabel runs over to Dipper, who is laughing and whooping). The two both perform a victory dance)

( The twins high-five each other. As this happens, they are immediately struck by a bolt of lightning. Cut to black. Sometime later, the Twins are awakening bed ridden in the hospital . They are being treated by Dr Matthews, as their co-workers are at their side)

Dr. Matthews:Looks like they're coming out of it.

Mabel:Where...am I?

Dr. Matthews:Don't worry, you're in a hospital. You're perfectly safe...assuming you have insurance. Now, you've suffered a serious shock, so we need to ask a few questions...what's your name?

Mabel: Mabel Pines.

Dr. Matthews:Where do you live?

Mabel: California with my mom.

Dr. Matthews:Good...and your occupation?

Mabel: I became a freshman soon so I didn't have a job yet.

Dr. Matthews:Mmm, looks like everything's normal.

Mabel:I just have one question for you, doc. Who's this guy?

(Mabel points to Dipper , laying in the adjacent bed to him. Everyone gasps)

Dipper:Hi, I'm Dipper. I'm surprised we never ran into each other.

Soos: Whoa, you dude really don't remember each other?

Mabel: What are you talking about, Soos? Why should we?

Dipper: Yeah, I mean, how can I remember someone I just met?

(Ford turns to Dr. Matthews)

Ford:How bad is it, doctor?

Dr. Matthews:They're suffering from a very specific form of amnesia...one that only targets the memories of their sibling ...

Mabel:We're sibling?

(Dipper and Mabel both stare at each other)

Dipper & Mabel:Huh...

Stan:Is it treatable?

Dr. Matthews:It's my medical opinion that you should go home and try your best to help jog their memories.

(Back at the shack, The Stan twins, Wendy and Soos are sat in the living room.)

Dipper: So you're saying we've been twins since we are born?

Stan:Yeah, since I met you and Dipper back in California I can't get hold of you two.

Dipper: Huh, I don't know if I see it.

(Dipper turns to Mabel)

Dipper:No offence.

Mabel:None taken. I feel like I remember falling off the bridge...but not this guy.

Dipper:Hmm, same.

Wendy: You guys really don't feel anything? Any connection at all?

(Dipper and Mabel stare at each other)

Dipper & Mabel:Hmm...

Mabel:Nope.

Ford:Oh, come on! You know how Stan and I have all our things like...

Stan & Ford:King of New Jersey! Pines, pines, pines, pines!

(Stan and Ford high-five)

Ford:And you kids have your things like...

Mabel: paint? Stickers ? I wouldn't advise that.

Stan:How about doing high...?

(Dipper and Mabel stare at Stan and shrug)

Wendy: Going on adventure...?

Dipper & Mabel:Hmm...

Dipper:Not really ringing a bell, sorry.

Stan:Okay, fine, we'll show you!

(Outside, Dipper is doing donuts in the cart while Mabel stands on the roof. Stan and Ford observe them)

Ford:Okay, you kids are doing great! Now see a gnome over there!

(Mabel grabs Jeff and spins it weakly.)

Ford:No, punch him in the face!

(Mabel punch Jeff in the face.)

Jeff: OW! I hope she remember the left blower.

(Where as Mabel seems to be enjoying herself, Dipper grabs Stan and Ford's attention)

Dipper :Are you guys sure this is okay? We're really doing some damage to the lawn out here.

(Stan and Ford glance at each other, worriedly. Later at Greasy's Diner Mabel is scoffing down a load of ice cream, sat with Dipper, Stan and Ford)

Mabel:Yeah, yeah! This is great!

Stan:Nice! How about you, Dipper? You feeling it?

Dipper:I guess it's just not for me. No offence.

Mabel: None taken.

(Mabel continues eating ice cream)

Stan & Ford:Hmm...

(Back at the Shack, Stan, Ford, Dipper and Mabel are walking back to the shack)

Mabel:Man, what an awesome day! This guy must be the greatest brother.

Stan:How about we try some of your stuff, Dipper? Some of what you like to do?

Dipper:Okay, cool! You mean like going to an adventure , or hanging with Ford or taking my Esperanto class?

Ford:Uh, well actually...you didn't do any of that with Dipper, so...

Dipper:Oh...

(Suddenly, Wendy appears on the house's porch with Soos, who is holding a VHS tape)

Wendy:Hey, we made something that might help!

Soos:A film!

Wendy:A fi- well, a video. We made a video of you two together.

(In the living room, the gangs gather around the TV)

Old Man McGucket :We went into the archives and put together this film as best we could.

Wendy:Video! It's really more of a -

(The video starts playing on the TV)

Wendy:Oh, it's starting!

(First up, a video clip of Dipper and Mabel on their 13th birthday day plays out. Mabel is sat at a table.)

Mabel (video):As your twin sister , it's your job to put gummy worm up to my nose 'til I pass out!

(Dipper approaches Mabel with a "Gummy Worm" bucket.)

Dipper (video):(laughs)You got it!

(Dipper starts puting gummy worm . In the present, the gangs are watching awkwardly as Mabel smiles)

Muscabel:(laughs)Nice.

Dipper:Hmm...

(In the video, a clip of Dipper sleeping is shown. Mabel has squirted cream into Dipper' hand and is tickling him with a feather. This causes Dipper to sneeze and shove his hand into his face, getting cream all over himself. The twins both laugh. Back in the present day, Mabel laughs at the video)

Mabel:Aw, yeah! Now that is funny!

Dipper:Hmm...

(Mabel laughs, then notices that Dipper isn't quite as amused)

Mabel:Oh.

(Back in the video, a clip of Dipper on the ground covered in tanning oil is shown)

Dipper (video):Mabel, I put on too much tanning oil and now I can't get up!

Mabel (video):Don't worry bro bro , I'll help!

(Mabel tries to pull Dipper up but just ends up flipping her over. she tries everything to lift him up. Back in the present day, the atmosphere within the living room is quite awkward as they struggle through the rest of the video)

Soos:(awkwardly)Wow, what wonderful memories!

(Mabel cringes)

Dipper:I, uh, I think I'm gonna call it a night if that's okay. Thanks.

(Dipper leaves the living room.)

Mabel:(sighs)Man, after watching that,I wouldn't even be my twin brother with me. I want you to give it to me straight, Grunkle Ford...am I not cool?

Ford:Well, it never really mattered. Dipper was there, so you were always cool to someone.

Mabel:Brutal.

(Mabel sighs as she walks over to the window. She puts her hands on the pane and sobs slightly)

Mabel:Without him, I'm just a loser. I gotta start taking this seriously. I can't let this slip through my fingers.

(Mabel brings her to her face, as another bolt of lighting strikes, appearing by his hand from her vision)

Mabel:Hmm!

(Meanwhile, at the Corduroy' residence, Dipper is playing a tune on his tuba in Wendy. He begins to sing)

Dipper:Animal ol-

(Dipper clears his throat and continues singing)

Dipper:Animal olives were packed in a jar.

(Dipper hears a knock on Wendy bedroom Wendy lets herself in)

Wendy:Hey, Dipper. Cool song. Mabel's at the door.

(Dipper sighs and makes his way to the front door. where Mabel is stood in the pouring rain)

Dipper:Yes?

Mabel: Bro, I know I don't seem very cool, but there's gotta be a reason we were such good sibling, and I don't wanna lose that. There's one thing to save our sibling-ship we haven't tried yet.

(Mabel brings up her hand, signaling a high-five)

Dipper:Listen, it's been a long day and I really need to recharge right now.

Mabel:Please, this is the last thing! Just slap me some skin!

(Mabel backs away into the middle of the road, still with her hand out)

Dipper:Hmm...

Mabel:Come on! Don't leave me hanging, bro!

Dipper:(sighs)If it's the last thing.

(Dipper makes his way over to Mabel and high-fives him in the middle of the road, where they are instantly struck by lightning again. Cut to black. Back at the hospital, Dr. Matthews is treating the twins again)

Dr. Matthews:Hospital again! So tell me, do you two remember each other yet?

(Dipper and Mabel stare at each other)

Dipper & Mabel: No.

Mabel:But we can't give up, we gotta do whatever it takes.

Dipper:I don't know, Mabel. Maybe this is all a sign that our sibling-ship isn't meant to be.

Mabel:Don't say that, Dipper!

(Dipper gets out of the hospital bed and makes his way out of the ward)

Mabel:Hey, what are you doing? You can't leave!

Dipper:Actually, I was thinking about going on a road trip. I have a lot to think about, like - what is a sibling really? What does any of this mean? Are we all alone on this big, blue pebble?

(Dipper heads out)

Mabel:Wait! Please, wait.

(Dipper leaves. Later, Stan is restocking some shelf inside Mystery Shack, when Mabel bursts through the door crying hysterically)

Stan:Kid?

(Mabel runs into her and Dipper room sobbing. Stan walks over to their bedroom door and knocks, as Mabel continues to sob uncontrollably)

Stan: Mabel?

(Stan opens the door slightly to look inside)

Stan:Mabel sweetie?

(Mabel is sat on her bed as a bolt of lightning strikes outside her window. She is holding a photograph of herself and Dipper with their arms around each other by the Cliff when Gideon was arrested)

Mabel:What's it gonna take for you to be my brother?

Stan: Kid I'm sorry, I don't know how to get your brother to remember you.

(Mabel continues to cry until he notices the Cliff in the background of the photo. She gasps and runs over to Stan)

Mabel:Grunkle Stan, you're gonna have to record Ducktective tonight, 'cause I'm not coming back without my twin brother.!

(Mabel runs off. Mabel is seen pushing the doorbell of the Corduroy Residence, and is greeted by Wendy, holding a plate with a bagel)

Wendy:You just missed him. He went to the bus station.

(Moments later, Dipper is heading to the bus stop as Mabel drives by in h the golf cart. Dipper notices her)

Dipper:If you came to change my mind, you're wasting your time.

Mabel:No, Dipper . I just wanna give you a ride to the bus station.

Dipper:Really?

Mabel:Really, it's the least I could do.

Dipper:Well...okay, yeah. Thank you.

(Moments later, Dipper is now riding shotgun in the golf car. Sad music plays on golf cart radio, and Dipper clears his throat)

Mabel:Uh, if you don't like the music, you can change it or whatever.

Dipper:Oh, no. It's okay.

(Dipper notices a sign for the bus stop)

Dipper:Well, looks like my stop's coming up.

(Mabel drives past the bus stop)

Dipper:Oh, uh, I think you just passed the bus station. Well, that's okay. I'm sure we can make a legal U-turn at the next light.

(Mabel, frustrated, steps on the accelerator and begins to speed along the road at almost 70mph, almost hitting a pedestrian attempting to jaywalk)

Pedestrian:Hey, I'm jaywalking here!

(Back in the cart, Dipper realizes that Mabel's intentions are not to drop him off at the bus station)

Dipper:Oh, no...oh no, we're not going to the bus stop? Where are you taking me!?

Mabel:I figured it out, bro. It all came together...in here.

(Mabel points at her head)

Mabel:They said that's where it all started. And now, that's where this ends!

Dipper:You're going off the rails, man!

(Dipper try to escape but Mabel glue Dipper seat on the cart.)

Mabel:You'll see...

(Mabel, now in the bridge when she and Dipper fall from robot Gideon , She drives through as Dipper screams, leading them to the bridge. Mabel brings her hand over to Dipper)

Mabel:Do you trust me, bro bro?

Dipper:No! No, I don't! Look at what you're doing, this is crazy! Please stop!

(Mabel drives the cart into the cliff as Dipper screams. Classical music, "Jesu, Joy of a Man's Desiring" plays as the twins fall into the bridge in slow-motion. Mabel still has her hand out in hopes of Mabel holding it. The twins both close their eyes tightly, and their memories of each other start to come back.

Mabel: Nope. Let's do it. (They get on the bus. Both Dipper and Mabel open their eyes and remember Dipper and Mabel 13th Birthday party, as well as their victory dance near the start of the story. They start laughing in slow-motion and face each other. Dipper holds Mabel's hand, as the speed of the story returns to normal)

Dipper & Mabel:I remember everything!

Dipper:Too bad we're gonna die!

Mabel:Not on my watch grappling hook!

(Mabel pulls out her grappling hook and fires a hook out of the cart to reach a nearby rock at the top of the bridge, pulling Dipper and Mabel back up to safety.
