"He's looking at me..." Brome heard his sister whisper to herself. She was not so inconspicuously watching Martin, one of the Mystery Shack's teenaged employees, while she cleaned bobbleheads made in the image of their Great Aunt (or Graunt) Polly. The siblings had been put to work helping out around the tourist trap as soon as they'd had some time to settle in.

"Why don't you just, I don't know, talk to him?" he suggested with an eye roll. Rose stared at him.

"After what happened last time?" she cringed. Yesterday, when they'd met him (and the handy-squirrel known as Feldoh), the mouse had introduced himself before saying something about a "rosty nose", which had taken several minutes to decipher. Brome still wasn't sure what that was about, but it had definitely been awkward.

"Well, he's proven that he can speak coherently," Brome observed, nodding his head at the customer Martin was currently ringing up, "so maybe this time you guys can make it through an entire conversation without crashing."

"I... Don't be so pushy, Brome. These things take time. And besides-" Rose's protests were cut off by Graunt Polly's appearance from the back room.

"All right, all right, look alive, everybeast. I need someone to go hang up these signs in the spooky part of the forest," the mole announced, displaying several signs that had advertisements with question marks and directions to the Mystery Shack on them. Rose, Brome, Feldoh, and Martin all glanced at each other.

"Not it," Rose said quickly.

"Not it," Brome followed suit.

"Also not it. You needed me to switch out the lightbulbs upstairs, remember?" It was Feldoh, this time. Graunt Polly looked annoyed.

"Martin, go hang these signs." She ordered.
"Oh, I would, but it's so far. And I just realized I never had my lunch break so..."

"I'd fire all of you if I could," Polly complained, frowning at Martin's lame excuse. Her statement didn't seem to have the desired effect, for she looked rather disappointed when no one took the hint and volunteered as tribute.

"Fine, then. Guess we're gonna have to do this the old-fashioned way," she said, "let's make it.. Eanie, meanie, minie… you," she pointed a paw at Brome. He groaned in dismay.

"What? No. Graunt Polly, there's something off about these woods… they're creepy and I always feel like I'm being watched."

"Noonvale doesn't have much in the way of real forests, Brome. It's gonna take some time for you to adjust to, well, the great outdoors," Polly told him, giving his headfur a ruffle. He looked to Rose for backup, but she didn't offer anything.

"I'm telling you – there's something weird going on in this town. Homesickness can't explain why the mosquito bites on my arm spell out 'beware'." Brome pointed out, rolling up his sleeve to show the others. Feldoh made a gagging noise. Rose raised an eyebrow and said,

"It looks more like 'bewarb' to me, and that's really only if you squint."

"Look, kid, that whole 'monsters in the woods' thing is just a local legend drummed up to attract more tourists," Polly tried to assure him, but Brome wasn't convinced. He had only been in Gravity falls for a day and he'd already seen bizarre glowing lights, heard strange noises, and been accosted by possibly radioactive mosquitos.

"But..." he protested as Graunt Polly plopped the signs into his reluctantly waiting arms.

"Stop being so paranoid and try to have some fun with this, eh, Brome?"

"No one believes anything I say," Brome muttered to himself as he nailed a sign to a tree. It felt like he had been out in the forest for hours. All by himself. With no one to talk (complain) to. Was it even legal to send children out into the forest to perform manual labor without supervision? He'd have to check the local child labor laws once he got access to wifi – yet another thing the Mystery Shack seemed to be lacking in.

"Ugh!" he cried. "Stupid Mystery Shack! Stupid signs!"

Kathunk! Brome kicked the next tree he came to and immediately recoiled. He yelped in pain, then cocked his head. Trees didn't make weird echoey noises… did they?

"Weird…" he commented, dropping the remaining sign on the ground so he could investigate further. Rapping gently on the tree – he didn't want to hurt himself – Brome listened to the oddly metallic sound the tree made on impact. Something was definitely off about it. He took the sleeve of his sweatshirt and rubbed away at the trunk. Textured brown paint and a healthy coating of dirt and grime gave way to old metal. Ahah! The entire tree was fake. In full detective mode, now, Brome examined the tree until he spotted a small handle.

With slight apprehension, for there was always a chance his actions would activate an army of laser equipped robots, he grasped the lever with both paws and yanked it down. Nothing happened. No grand reveal. No explosion. Just the sound of birds chirping in the distance.

The young mouse huffed in disappointment and turned to leave, wishing he hadn't gotten his hopes up. All his Sci-Fi TV shows and books had lied to him. Cool things never happened in real life. The world just didn't work that way. But then, the creaking of a rusty hatch forcing its way open somewhere nearby caused him to stop in his tracks.

Brome circled the area, searching for the source of the sound. The switch must have done something, after all. He checked every nook and cranny, below each bush and on top of every rock and stump. His query remained elusive. Whatever the lever had opened was clearly well hidden. Brome took a step backwards, hoping the action would give him a different view of this patch of forest.

In a way, he got exactly what he wanted; the fallen tree he tripped over certainly forced him to see the area from a different angle. But the unexpected fall wasn't very pleasant and Brome couldn't help but wonder how badly he'd have to hurt himself before his parents would let him come home. He lay on the ground for a moment, half tempted to sink into the dirt and become one with nature. Thankfully, such drastic actions did not end up being necessary.

It was no wonder Brome hadn't noticed the bizarre hole the switch had uncovered. Half buried by the log and built from camouflaged materials, he would have missed it completely if not for the fact that he'd practically fallen right on top of it. He sat up, thoughtfully. Whoever had installed this hidden treasure trove obviously hadn't wanted anyone to find it. How long had it been since someone sat where he now sat? Since somebeast had peered into the hole to examine its secrets? Brome gently removed an object wrapped in old newspapers, bursting into a fit of sneezes at the resulting cloud of dust that had floated into the air.

It was old. Old-old, as in more than just a few years old. The newspapers were from several decades ago. Their edges had curled with age, and some of the lettering was too faded to be legible. Fortunately, Brome had little interest in the newspaper; the item it protected was far more intriguing. A journal. And journals always had juicy secrets written in them – he'd learned that from snooping in Rose's bedroom (though this journal would inevitably be much more interesting than his sister's diary).

The journal's design was simple enough. It was made of thick brown leather with the insignia of a paw print on the front cover. Brome wasn't sure what kind of creature would have an entire extra toe. He also wasn't sure he wanted to find out. What if the journal contained something bad? Something he wasn't supposed to see?

It must have been hidden for a reason, after all. The young mouse sat for a moment, pondering his options. He could, of course, bury the journal and get back to work hanging Graunt Polly's signs. He could also take his chances and open the book regardless of ancient curses or government Intel. It was a difficult choice.

"Alright, mystery beast. Let's see what you've been hiding," Brome muttered when his curiosity finally got the better of him. He hummed thoughtfully and flipped through the first few pages. They were covered with sketches of creatures he had never seen before. Detailed notes and memos accompanied many of the sketches.

"It's hard to believe it's been six years since I began studying the strange and wondrous secrets of Gravity Falls," he read aloud from the page that had the most writing. Six years was a long time to be stuck in this place. The author must have had an awful lot of spare time on their paws to create such an elaborate journal. Flipping through the journal some more, Brome found himself growing more intrigued with each page he read.

Eventually, the writing and sketches grew increasingly erratic and less caretakingly organized. Notes that made no sense lined the margins in some places. One page in particular had the words Trust No One scrawled across its top in large lettering. Brome read the rest of the entry with bated breath, "Unfortunately, my suspicions have been confirmed. I'm being watched. I must hide this book before he finds it. Remember: in Gravity Falls there is no one you can trust." He paused, confused. That seemed… harsh. But if Gravity Falls really did have a dark side-

"Watcha doin?" someone said, sending Brome into a frenzied attempt to hide the journal behind his back. He groaned when he realized who it was. His sister gave him an awkward wave.

"Rose! Thanks for that. I really needed a heart attack today," he stated flatly.

"I didn't mean to scare you," Rose told him, sitting down on the fallen tree, "Graunt Polly sent me to check on you."

"Oh," he said. He felt a little foolish for being so easily shaken. The journal's tone was clearly getting to him.

"So… what were you reading that you didn't notice me coming your way?" she asked.

"It's nothing," Brome said quickly. Rose hummed in response, clearly skeptical.

"Seems like pretty interesting nothingness. You were really invested in it."

"Well… it's not nothing nothing," he admitted, "Just not something I should show you out here where anyone could happen to walk by. Let's go somewhere more… private."

"Alright. But now I'm curious. This better not be evidence of aliens, or I'm going to be very insulted that you didn't show me right away," Rose teased, ruffling his head fur. Brome winked at her and stood up. He waved the journal at her before taking off in the direction of the Mystery Shack as he said,

"You'll just have to wait and see."

After all, surely the book journal hadn't meant sisters when it said trust no one… right?
