Summary

The Corduroy's carry around silver headed axes that the town believes comes from their lumberjack tournaments, but Stan Pines knows different. They're part of his insurance plan he set up with Manly Dan years ago when he realized his stay in Gravity Falls was going to be a long one. Ford, Mabel, and Dipper find out about this little insurance plan when Dipper's attempt to out the mailman work a little too well and he outs Grunkle Stan as a werewolf as well.

Chapter 1

"Hey dudes, whatcha doin'?" Soos asked the kids as they seemed to be keeping a lookout for something.

"I'm helping Dipper with one of his mysteries. He promised to have a tea party with me and Waddles after!" Mabel cried happily.

"It's a small price to pay for science." Dipper sighed but then smirked when he pulled out a bag full of dust.

"What's that? Some sort of powder that lets you see people's auras depending on their mood?" Soos asked as he leaned down to inspect the silver, slightly rainbow-y colored dust.

"No, not exactly," Dipper said.

"Though that would be totally awesome!" Mabel added.

"True. I'm sure there's something in the forest. Later we can-oh here he comes!" Dipper exclaimed. He and Mabel rushed to their positions.

Soos stood back, normally always itching to be part of the twin's schemes. But it wasn't until it was too late that he realized what that powder stuff was.

"DIPPER NO WAI-"

Dipper blew the powder into the mailman's face and the result was almost instantaneous. The mailman's eyes glew a bright yellow and he let out a low growl. If it wasn't for Soos who pulled the twins back in time, they would have met his sharp claws. Soos did his best to block the werewolf's path from him and the twins but he was running out of things to throw between them and would soon be pressed against the wall...literally.

The werewolf mailman let out an angry roar. From the basement, Ford's voice could be heard.

"KIDS!"

Just as the vending machine opened, and the werewolf was going to lunge at the terrified trio, a blur lunged at the werewolf. It took a moment for the Pines family to realize the thing rolling around with the werewolf was Stan.

"Stanley!" Ford cried in panic as he watched his brother wrestle with the furry beast.

The wolf's claws were dug into Stan's shoulder, blood soaking his suit. Stan was doing his best to keep him at bay while trying to push him towards the door. Ford was going to grab one of the displays to help his brother but the wolf roared again, shook his mane and whatever dust Dipper had thrown on him, fell on Stan, which made the older man freeze.

"Oh no...Dudes, we gotta get out of here! Like now!" Soos exclaimed as he tried to carry the twins out of there.

"What? But Grunkle Stan needs us!" Mabel cried.

"He's hurt, Soos! We can't leave him against a werewolf!" Dipper yelled, guilt coursing through him. Why did he think this was a good idea?

"This could get dicey. Take the children to safety. I'll help Stanley." Ford told Soos calmly, agreeing that he should take the children.

"No, you need to come too, Mr. Other Pines! It's not safe here! We need to call Wendy and Manly Dan!"

"What are you talking about?" Ford ask with a raised brow. He was about to tell him how he knew how to fight things stronger than a mere wolf when he noticed something wasn't right with Stanley.

A moment later he knew why Soos wanted them all gone.

Stan's eyes glowed red. The pressure in the room seemed to drop before an ominous low growl escape the older man's mouth. Before their eyes, Stan shifted into a hairy wolfman beast with claws and fangs and a crazed look in those red eyes.

The mailman whimpered and tried to dislodge himself from Stan, but Stan wasn't going to let it end now. He growled before biting into the other wolf. Their fighting caused them to roll around again, knocking things over and making it hard to see who was clawing into who.

The Pines family watched in horror, not really being able to accept what it was they were seeing. So focused on the fight they didn't see the door open and Wendy step in.

Her eyes widened but she was only shocked for a moment. When that moment ended she got into gear. She hopped behind the counter and pulled out the crossbow she had hidden behind there for this reason in particular. She aimed the crossbow at Stan's shoulder and when she had a clear shot, she fired.

Stan roared as he fell back. The mailman took that opening and burst through the window. Wendy jumped the counter again and reloaded the crossbow. While she aimed, she yelled to Soos, "Soos! Get my dad on the radio and get my brothers after the mailman!"

"Right! S'cuse me, dudes." Soos put the twins down and went for the walkie-talkie and radioed Manly Dan.

"Wendy! What are you doing!?" Dipper cried as he and Mabel ran in front of her and blocked her from shooting Stan again.

Wendy pushed them behind her. "I'll explain later. Get upstairs, now!"

When she steadied her aim again, Ford grabbed the bow and lowered it. "You're not going to shoot my brother again!"

Before she could explain anything, Stan lunged at them with a growl. Soos managed to tackle Ford out of the way while Wendy shot another arrow into Stan. He whimpered like a wounded animal and took a few steps backs.

"GRUNKLE STAN!" Mabel shrieked.

"Wendy, there's gotta be another way!" Dipper yelled.

"Stanley, stop this!" Ford begged. He tried to meet his brother's eyes. To find any glimpse of the Stanley he knew and loved. But in those red eyes and hairy face, there was only beast, no man. "I know you're in there Lee! You have to be! A monster didn't bring me back, my brother did! Stanley!"

Stan was panting, crouched low, growling softly so it was more of a rumble.

"I think it's working Grunkle Ford," Mabel whispered.

Stan's eyes then narrowed and his stance changed. He was about to pounce. Ford pushed the twins behind him but held his ground though his hand reached for his lazer gun.

Wendy reached for something in a drawer behind the counter and threw it at Stan's feet. When he lunged, he was met with a circle of black powder that created a force field. No matter how hard Stan pushed against it, it wouldn't let him through.

The door chime rang and they looked over to see Manly Dan enter with a few tools. One of them being a dog muzzle leash dog catchers use on dangerous dogs.

Dan nodded to Wendy, who nodded back and went to help him with the tools he brought. The lumberjack then looked to Soos and said, "You best get these kids outta here…"

Soos nodded and pushed Dipper, Mabel, and Ford towards the door that led into the house part of the shack.

"What are they going to do to Grunkle Stan?" Dipper asked, voice full of worry and guilt. In his mind, it was all his fault.

"Don't worry dudes, it's gonna be totally fine. Okay? Okay. Hey! Let's go to the kitchen and make some grub, huh?" Soos said with forced cheerfulness as he rushed the rest of the Pines into the kitchen. He pulled out a pot and placed it on the stove and started the fire before grabbing a pitcher and filling it with water from the sink to pour it into the pot. "How bout some mac'n'cheese? Huh? That's good, right? Food for family night. A normal family night where everything is okay because nothing is wrong. Nope, nothing is-"

"Soos!" Dipper and Mabel both called out his name.

Soos stopped and sighed, pulled himself together and faced the family. "They know what to do, dudes."

"How?" Ford demanded. He was trying to wrap his head around all of this. Trying to determine when Stan could have been bitten. How he could fix this.

"We got it under control," Wendy said as she came into the kitchen. She looked around before pulling a twenty out of her pocket and handing it to Dipper. "Look...it's a long story. And you'll get it. But for now, how about you take Mabel and Soos to get some ice cream and other junk for Stan?"

"Huh? How's that going to help?" Dipper asked.

"Well…" Wendy struggled to find the words for a bit. "After episodes like this, Stan's going to wake up feeling achy and tired and moody. Junk food helps him feel better. There's not much you guys can do here, so this is something. I promise he'll be okay."

"You shot him. Twice." Mabel deadpanned, not really happy with Wendy at the moment.

Wendy frowned at that but nodded in acknowledging it. "I know. But I promise dudes, I know what I'm doing. It wasn't lethal...but Stan is...powerful. Now go. I promise you'll get answers later." She nodded to Soos and got a shaky nod back.

Soos ushered the kids through the door and into his truck.

Wendy watched them go. She knew Soos hated when this happened. It always shook him up bad.

"Now that the children are gone, can someone please tell me what the hell is going on? Where's Stan?" Ford demanded as he tried to head back to the gift shop. His way was blocked by Dan though.

"Go check in on your brothers, kiddo. Mr. Pines and I are going to have a talk." Dan said. He grabbed a Pitt Cola before sitting down.

Ford wanted to go check in on Stan.

"He's going to be out for a few hours," Dan commented, sensing the torn decision in the other older Pines twin.

Hearing that, Ford sighed before taking a seat across Dan.

"When was my brother bitten?"

"'Round 35 years ago, give or take."
