"Come on, Dean. This could be a real lead." Sam sat at his laptop, body slightly turned in his chair. His hands popped up slightly as he spoke to emphasize his point to his brother.

Dean took a large swig of his whiskey. "Too thin, Sam."

Sam shook his head. "It's the first anything we've had in weeks."

Another swig of the whiskey. "It's probably only a few earthquakes and some crazy locals."

"And what if it's not?" Sam did have a point but there was no response from Dean. So the younger brother waited before finally giving up with an exasperated sigh. "Dean, the local paper states that there were gravity anomalies as well as several federal agents who showed up and then just left inexplicably. Sounds like enough to me."

"It says gravity anomalies that were then discovered to be earthquakes." Dean pointed out.

Sam smirked. "Either way it sounds a little, I don't know… supernatural. Doesn't it?"

Dean gave a deep sigh deciding to that entertaining Sam was much easier than fighting him. "Fine, two days." He held up his hand then dropped it back to his side. "Gravity Falls, here we come."

*GFS*

Dipper jumped up on the counter, his legs dangling over the edge and journal 3 in his lap. This was his favorite thinking spot, with Mabel spinning around on the chair behind him.

"Are we going on a monster hunt today?" She attacked his back with excitement.

"I don't know." Dipper shook his head. "Grunkle Ford doesn't want us to get too far away from the shack."

Mabel gaped at him. "Grunkle Stan took us on a road trip. I don't think we can get much farther than that. We'll be fine." When Dipper didn't respond she began shaking him like a rag doll. "We haven't done anything fun for like forever."

"We played mini golf with eyeballs in the attic last night until Stan forced us to go to bed." Dipper continued to flip through the pages of the journal with a pen in his mouth and the black light on the counter.

Laying across the counter Mabel flipped her hands around in Dippers face. "I need to do something fun now or I'll die."

Dipper sighed and smiled at his sister. With a slight nod Dipper began pouring through the pages of the journal. "So what do we want to look for?"

*GFS*

"Sure are a lot of signs." Dean muttered without amusement. "Guess this weirdo really likes his Mystery whatever."

"Mystery Shack." Sam corrected from the passenger side of the Impala.

"Whatever. Anything with the word Mystery in its name is bad news to me." Grumbled the reply.

"Afraid Gabriel is…"

"Don't even start that." Dean cut Sam short, his finger pointing accusingly at him.

A chuckled followed as Sam turned his head to face the window.

They pulled up to an old rundown shack with the S following off the building's roof label, so it now read Mystery Hack.

Dean looked up at the old wooden structure. "I don't know Sam. I mean, you sure this is the place? Kinda looks abandoned."

Just as the words escaped his mouth a teenage girl with fiery red hair and a green plaid shirt walked up a path and into the shack where a man could be heard from inside, truly upset about her being late.

"Yeah I think this is the place dean. The article said the agents were investigating this tourist trap." Sam held up the printout of the article.

"Why would anyone care about a place like this?" Dean leaned forward to get a better look of the rundown shack.

"Let's go find out." Sam opened his door and began walking towards the main entrance.

*GFS*

Dipper glanced over the journal when Wendy walked in and Grunkle Stan began yelling at her for being late. But this was a common occurrence and in a matter of seconds the exchange was over, Wendy went to her usual stool behind the counter with her nose in her magazine and Stan went prepping for whatever poor sap walked through the door next.

Mabel was reading the journal over Dippers shoulder and stopped him on a random page. "Let's go find this one, Dipper!" She yelped excitedly. "His face looks so adorable!" She smashed her cheeks as she spoke.

As Dipper eyed the page two men walked through the door. One extremely tall with long dark brown hair and the other slightly shorter with a slightly lighter shade to his much shorter hair.

"Mabel, this is the Leprecorn. Do you really want to hunt one right after fighting the unicorn?" Dipper must have spoken too loud because the shorter man suddenly turned and began moving towards them.

Raising her fists in the air to fake being in a mighty stance Mabel yelled out, "I'm gonna find the Leprecorn!" And with that Mabel shot off her chair and began running towards the door.

"Wait up!" Dipper jumped off the counter but found himself off balance and ended up falling flat on his face. As he pulled himself up to run after her a hand caught the back of his jacket.

"Where do you think you're going kid?" Grunkle Stan spun Dipper around to face him.

"Mabel…" Dipper pointed out the door Mabel had left open in her rush to get outside.

"You can go play with your sister later. Right now I need you to man the shack." Stan jammed a thumb behind him. "These guys seem like tough customers but I bet they'll buy something if it comes from a young face like yours. Besides I got a tour group to run."

"But Wendy is here." Dipper protested, with Bill out and about he wanted… no, needed to protect Mabel.

Grunkle Stan ignored Dipper's protest and leaned over now to poke Dipper lightly in the chest. "Make me proud." Then hurried off to the Museum portion of the shack.

Dipper sighed and glanced out the door but didn't risk Stan's rage. Instead he gave his attention to the two men. The taller one was wandering around with a metal box with an antenna at the top in his hand, the shorter looking right at Dipper.

"Can I help you find something?" Dipper asked the man, pulling his hat down over is eyes in frustration. He hoped to get this done as soon as possible so he could go after Mabel.

*GFS*

Dean smiled down at the boy, who he had heard the girl call Dipper. "Actually I have a few questions."

Dipper folded his arms uncomfortably. "What kind of questions?"

Dean squinted at the kid. "What do you know about those gravity anomalies a few weeks ago?"

Dipper's arms fell to his side and he took a few nervous steps back. "Gravity what's?" His voice was shaking.

Dean jutted his lip out slightly and nodded before speaking. "I guess they were reclassified as earthquakes."

"Oh. Haha." Dipper gave a fake laugh and put his hand behind his head. "I don't know much about earthquakes. I'm sure you could google them."

Shaking his head Dean chuckled and turned to look for Sam who was attempting to question the red head but she didn't seem to be paying much attention. He turned back to talk to the kid again when the vending machine suddenly burst open.

*GFS*

Grunkle Ford stormed out of the hidden door to see Dipper leaning away from a tall man who was now staring at him. An even taller man stood a ways off trying to talk to the girl who always sat behind Stan's gift shop counter. Ford immediately moved between Dipper and the shorter man.

At first Ford wasn't really sure what to say. He didn't usually come out during the day but he hadn't retrieved food to the basement the night before and now found himself hungry and there weren't usually people in the shop when Stan was running tours.

Ford stood as tall as possible so his height was similar to the man, he did not like the sight of this man evidently interrogating Dipper. "May I help you?"

The shorter man stood a little straighter and extended his hand. "I'm Dean and that's my brother Sam. We're just going through town, wondered about the gravity anomalies you experienced a few weeks back." As Dean spoke Sam came to stand by his side.

"Didn't you read the papers? They were nothing more that earthquakes." Ford retaliated. "Now if you would kindly leave my grandnephew alone I'm sure his sister is getting into all kinds of trouble." Ford looked down at Dipper and gave him a nod.

Dipper took this as his chance and bolted out the door to look for Mabel.

"Sorry to have taken your time, Mr…?" Sam was trying to get anything to prove to Dean that this wasn't a wasted trip.

"Pines. Now if you would kindly leave." Ford pointed to the door.

The brothers gave one another a look before leaving without anther word. They climbed into the impala and drove down the road.

*GFS*

The brothers were silent for several minutes.

Finally Dean spoke. "I still really don't think this is our kind of thing but I will admit that that kid was lying through his teeth."

Sam made a sour face before responding. "There was no EMF but that place really was weird. I still think this is a job."

Dean scoffed.

"I'll do some research on the family and the town when we get back to the motel." Sam was knew if nothing came out of this he would never live it down.

*GFS*

Dipper found Mabel out in the woods yelling up into a tree.

"What… are you… doing?" He had run all the way to her and now was entirely out of breath.

"That squirrel took my crackers!" She screamed, waving her arms above her head wildly.

A slight chuckle slid from Dippers throat before he grabbed her shoulder. "Come on, let's go back to the shack and I'll get you a new crackers." Mabel always had food of some kind on her.

Mabel turned and pursed her lips out. "What about the Leprecorn?"

With a shake of his head Dipper began pulling his sister along behind him. "The two guys at the shack were asking weird questions. I think Ford will want us back as soon as possible."

The twins arrived in the gift shop to see the older twins arguing.

"They were paying customers!" Stan yelled.

"And they were interrogating Dipper." Ford had his arms folded and was as if Stan was lower than the dirt of the earth itself.

"He's a weird kid and it's a weird town. People can tell." Stan retaliated, obviously not knowing Dipper and Mabel had reentered the shop. "And it's all because of you and those stupid journals of yours."

Dipper let his mouth drop open but before he could respond Mabel had grabbed the back of his vest and pulled him around the edge of the room. They were on the other side of the room by the time they were noticed.

"Kids!" Stan sounded truly shocked.

"Ah, Dipper. I need to talk to you about those men." Ford called out before coming to kneel before Dipper and Mabel. "What did they want? And how much did you tell them?"

Dipper looked slightly to the side before responding. "They just asked about the anomalies. I didn't know what to say but we didn't talk much before you showed up."

"Hmm." Ford tapped his chin. "They couldn't have been possessed by Bill, he can't enter the shack. But they might have made a deal with him." He sighed and stood, turning to face the opposite direction as he thought.

Stan stepped up to the kids. "You two had better get to bed, it's getting late."

*GFS*

"Hey come check this out." Sam beckoned Dean over. "According to this article Stanford Pines owns the Mystery Shack. He lived there for a while before his twin brother came to visit and a few days later his brother died in a car accident. Signs pointed to sabotage but nothing was ever proven. Then just after that Stanford suddenly went from all brilliant scientist to crazy criminal with a tourist trap, practically overnight."

Dean stared at the computer screen. "That doesn't make any sense. The guy that greeted us claimed to be Stanford Pines and the guy who came out of the hidden door looked just like him but there was no way it was him. Was there another sibling?"

Sam scrolled around on the page for a few seconds. "Yeah, there is a sister but she's several years younger and lives in California."

"Anything else we should know about this family?" Dean took a chug of the beer he had previously retrieved from the fridge.

A small laugh from Sam followed. "Apparently about a month ago the two kids were attacked by a giant robot controlled by another little kid. He's currently locked in the Gravity Falls prison."

With this news came Dean almost spitting the beer from his mouth. "Did you say giant robot?"

"Yeah, I guess I did." Sam scrolled the page a little more.

Dean gave a fake smile with a slight shake of his head. "Alright. What's this kid's name?"

"Gideon Gleeful." Sam read aloud then leaned in closer to the screen to insure he had read the name correctly.

"Rock, Paper, Scissors?" Dean gave Sam a sideways glance before promptly losing the game.

"Okay." Dean raised his eyebrows a little as he spoke. "I'll go interrogate Gleeful, you see what more you can find out about that family. You'll probably get more out of the kids, the old guys are a little…" Dean trailed of but brought his hand up and shook it a little.

"Sounds good." Sam checked his watch. "We'll start bright and early tomorrow."
