"Pancakes are almost ready!" Stan called from the kitchen. Dipper and Mabel were laying the table, casting glances at the woman sitting in front of the TV and watching the news. For Dipper, this was far too awkward a situation; were you supposed to talk to the random stranger, or would that be rude?

Mabel on the other hand, had no such inhibitions.

"So what's your name? I'm Mabel!" She leaned right over the woman, hair falling into the stranger's face. "Why'd you come to Gravity Falls? Know any cute boys?"

"Mabel!"

The woman laughed, brushing hair out of her face. "You're an energetic one. Is that your brother?"

"Yeah, this Dipper! We're twins." She waved him over. "Come say hi, Dipper!"

Dipper nervously waved. "Um, hi."

"He's kinda dorky, but I love him all the same."

"And the bloke in the kitchen is your..."

"Great uncle. We call him Grunkle Stan!"

She nodded. "So your parents, where are they?"

"At home! We're just staying for the summer. Now, it's my turn to ask you some questions!" She poked the woman's fur coat. "Ew, is this real?"

"Mabel!"

"Hey, animal coats are mean!"

The woman laughed. "Don't worry, I'd sooner wear a human coat than one of those. I just like how soft it is."

Mabel gave the garment a proper stroke, and her eyes went wide. "Ooooohhhh, so soft! So... soft..."

"Alright, who wants pancakes?" Stan burst into the living room. "Mabel, stop stroking that poor woman and come sit down."

The woman smiled. "Oh, I don't mind. She's a wonderful young lady, Stan."

"Ehhh... thanks?"

Dinner passed well enough, with most parties absorbed in their food. The woman kept glancing at the TV. One could had to wonder why; Sandra Jimenez going on about woodcutting wasn't terribly interesting, to say the least.

Stan gulped down a mouthful of pancake. "Lookin' for something?"

The woman nodded. "Does this television have any national news channels?"

"No, the damn thing's only local. Why?"

"I had an interview recently. I was wondering if I could catch it."

Mabel leaned forwards. "You're famous?"

"You could say that."

"Oh my gosh, really? Why?"

The woman smiled. "Maybe tomorrow, you could switch on the telly and find out. Right now, I think I'm headed to bed. Goodnight!"

"Goodnight, Miss..." Stan blinked as she walked off. "Hey, did we ever get her name?"

"No, but I like her!"

"You like everyone, Mabel." Dipper crossed his arms. "Was it just me, or was she a bit... weird?"

Stan nodded. "Yeah, she's weird. All that stuff about being famous? Ha, fat chance! But don't worry, I've glued down anything she thinks about taking, so I'm not worried." He patted the chair and then stood up. "Right, so who's up for some Ducktective?"

It was midnight. Stan, Dipper and Mabel were snoring before a dimly lit TV, some program quietly droning in the background. All in all, a peaceful scene.

A furry figure entered from the side, lit a muted blue from the television. She moved silently across the room to Mabel, happily snoozing on the arm of the chair. Mabel, who had her arm wrapped around Stan's chest and her head resting on his shoulder.

The woman smiled down at her with glistening teeth. She took the fur coat off of her shoulders, gently wrapping it around the girl. Once she had done so, she removed Mabel's hand from her uncle's – incurring a groan and frown from her in the process – and leaned over it.

One second passed, then two.

The woman then straightened, still smiling, and walked back to the spare room. Three hours later, police sirens stirred Stan from his sleep.

"Huh... what?" The conman jumped at the sight of a fleet of police cars blazing up to his door. His hand instantly went for the smoke bombs stashed under the couch, only to find them glued to the frame. "Dammit! Why did I glue these in the first place? You're losing it, Stan!"

Mabel raised her head. "What's happening?"

"Grunkle Stan, why are the police here?"

"Kids! Don't worry, I'll handle this. As long as nobody mentions a black truck, we should be good." He raised an eyebrow at the sound of a helicopter. "Though I gotta say, this seems a little overkill for pug smuggling."

"Police!" The door was kicked down, and the three suddenly found themselves blinded by a half-dozen blazing flashlights. "Hands in the air! Now!"

Stan moved in front of Dipper and Mabel, holding his hands up. "Hey, hey, there are kids here! What's with the SWAT team?"

"The residents are safe." One officer was saying into his radio. "Extracting now."

"Huh?" He blinked in confusion, letting himself be led outside. "Wait, who're you arresting then?"

They said nothing, ushering the three outside and running right back to the house. Stan watched in confusion as the helicopter spotlight swept across the Shack.

"What's going on?" Mabel moved to take her brother's hand, but instead winced in pain. "Oww..."

"You okay?"

"Yeah, my hand..." She held it up to the light, where one could clearly see bite marks and dried blood. "When did this happen?"

Stan looked down and took notice. "Mabel, sweetie, what happened to your hand?"

"I don't know!"

"Police! Open up!" A shout came from the house. "You're surrounded!"

Stan had had enough. "Right, well, I'm gonna find somebody in charge and ask them what the heck is goin' on. You kids stay here."

Before he could do so, however, the team suddenly came out, two firmly holding the B&B guest in a night gown with her hands behind her back. She winced in pain as the team shoved her along, but otherwise kept an easy, peaceful smile on her face.

"It's you they're after?" Mabel's eyes widened as she was led past them. The woman turned, shooting her a cheeky grin, and spoke.

"See you in a week."

Then she was gone, surrounded by the SWAT team and loaded into a police vehicle. Dipper, Stan and Mabel stared after her, dazed and confused until a man with a clipboard came up to them.

"Hi. I'm Detective Weathers, and I just want to ask you a few questions..."

That morning, they turned on the local news.

I'm Sandra Jimenez, and today we have actual, exciting news! The serial killer and kidnapper Jane Smith, otherwise known as 'The Dog Terror' was apprehended at the Mystery Shack in the early hours of this morning. Smith escaped police in a lengthy car chase yesterday, fleeing to Gravity Falls until somebody recognised the car and alerted the authorities. Both the Dog Terror and her car are in police custody, where they are already discovering disturbing secrets about this mysterious killer. The trunk of her car was discovered to have been full of the bodies of her kidnapping victims, all of them brutally-

Stan shut off the television, turning to his pale grandchildren with an equally blanched complexion. "Hot Belgian Waffles, she was in our house. I served her dinner!"

Dipper shuddered. "And the car with all the bodies... it was parked right outside!"

"And she bit me! Who does that?"

There was a long pause, and then: "Kids, I'm giving Soos his break room back."
