Hello everybody! This is just my contribution to the Gravity Falls fandom. This is just my idea on things, and I don't know where these ideas of mine take place but they do and it's just how things are! Okay, here we go~!

Disclaimer: Okay I don't own Gravity Falls.

Warning: It's Gravity Falls. So blood and stuff.

Here we go~!

Dipper was having a rough week.

First of all, Grunkle Stan suddenly wanted to hang out with the twins more. And by hanging out it was basically Mabel + Stan vs Dipper in an all-out pranking war. Needless to say, Dipper lost. A lot.

Secondly Stan was acting weird. And it wasn't normal weird. It was weird weird.

Like, suddenly the woods wasn't the best place for them to go alone. Together or with all of them was fine, but Stan acted like suddenly the woods was a forbidden place. It put both Pine twins on edge. One day, Dipper had to open his stupid mouth.

"Grunkle Stan, can I ask you something?" Dipper asks, fidgeting in place and messing with the ends of his fraying vest.

Stan raised his eyebrows at his nephew, and slowly nods.

"Is it about the sweat thing? Cause Dipper we already went—"

"It's NOT about the sweat thing!" Dipper quickly intervened. God he wanted to ask a question not relearn what his body was going through. That was torture enough the first time around.

"Then what is it?" His great uncle asks, now looking genuinely interested. The 12 year old sighed, and cleared his throat.

"What is going on, Grunkle Stan?" He asked, and actually saw his grunkle freeze. This alone made him want to push his uncle more, but he held his tongue. Maybe then he'd finally get answers.

Stan sighed, and took off his glasses. Dipper never really saw his uncle look so old, but when those glasses came off, it was like looking into the future.

His grunkle's face looked worn, and he looked his actual age. His mask was slipping off now, and Dipper saw fear there. He was afraid of something, maybe something that Dipper and Mabel didn't know anything about? Dipper wasn't sure, but seeing emotions that weren't anger or humor was frightening enough. Fear was something that did not belong on that strong willed face.

"Dipper, I'm just worried about a few things, alright? Might be my old mind just worrying me but it's nothing you need to worry about. But could you do something that might make me feel a whole lot better?" His Grunkle suddenly asks, causing the young boy to nod.

"Sure Grunkle Stan, what is it?"

"You two still have your necklaces that I gave you?" The question asked was not something Dipper was expecting, but he nodded and pulled out the necklace which was previously hidden under his clothing. The sight of the jewelry calmed the older man greatly. Sighing, he sank into his arm chair.

Dipper examined the piece of metal in his hand. It held the symbol of what looked like Stan's hat, whatever that was called. For whatever reason, Stan was now relaxed and Dipper just needed to go with it.

When Mabel walked into the room, Stan asked her the same question. She eagerly nodded and showed him her "improvements" AKA she put gems or anything that was shiny on the necklace to make it pretty and bedazzled. Stan smiled and ruffled her hair, and all three of them watched poorly mad TV shows for the next few hours, until Mabel and Dipper ended up falling asleep in each other's space.

Stan watched his two great nieces and nephews, until he realized that they were fast asleep. Sighing, the old man felt a smile tug at his lips, and he slowly arose from his chair. It was time to get to work.

Stan popped his back and cracked his neck. Sparing one last look at the twins, he picks up a blanket and lays it on top of them, watching the two reach toward each other underneath said blanket. Thinking back to a different time, Stan quickly and quietly walked to the vending machine.

Scanning the area around him, he quickly pressed in the correct digits to unlock the secret door that lays behind the vending machine. Taking one last look at his what he considered children, he walked into the secret passage way.

Making his was down the secret passage, his thoughts trailed down to the creature that he was currently, shall he saw, "housing". Said creature had a name, but he didn't want to get into that right now. All he knew is that this creature was best kept under lock and key, since it was impossible to kill. And he needed to be careful when around it. If he lost concentration for just a few seconds, that thing would attack his mind.

Reaching the bottom of the steps, Stan had to stop and take a deep breath. Shaking his head, his got rid of all thoughts containing his beloved children and focused on the task at hand. Placing on his mask, eyes giving away nothing, Stan entered the room.

Inside the room, or better yet in the center of the room, lay a container. Inside the container, there sat a small yellow triangle. It was slouched over, but as soon as the door was opened, it up in the air, floating, and all it's features exposed. It had an eye was long lashes in the center of it's body, with a small bow-tie and top-hat to give the object some sort of gentleman-like fashion.

However, when it spoke, it was anything but gentlemanly.

"Welcome back, Fez! It's been a while, yeah? What, like, 12 hours? That seems about right." The triangle mused, it's voice amused and high pitched. Stan gave no look of amusement, and stared straight at the creature.

"Are you willing to talk?" He asked, hands behind his back as he approached the monster. Said monster made a sound that must have been laughter, and wiped a tear from his eye.

"That was a good one, you should tell it at parties Fez." The monster gasped out, as if Stan had told him a funny joke. Maybe to this creature it was, but Stan was only growing irritated. Keeping his anger in check, he tried again.

"You can't stay quiet forever, you know. We both know how much you love to talk." Stan continued, as if he hadn't been interrupted by the rude laughter. The creature hummed, and floated into a circle.

"True, but you forget that my topics are endless, seeing that that's how old I am." The monster said, his voice hinting a smile. Stan rolled his eyes.

"You'll crack, I've already got you to expose half the reason why you were here. I'm a patient man, Bill Cipher. And I'm a man who can wait."

"You and I know that the man who could wait died a long time ago, Stanford Pines." Bill growled out, his voice dropping from it's normal highness to a deep anger. "And you know I am not a force to be trifled with. You want somebody else to get hurt too in this stupid mission for answers?" Bill questioned, and before Stan could push it down, an image of Mabel and Dipper flashed into his mind.

The demon grew still as he stared at Stan, who narrowed his eyes and cursed, kicking himself for being so foolish. How could he have let his guard down?! He was trained for this! Must have been his age…

"Who… Who are those two?" Bill asked, his voice softer than usual. Stan was on alert immediately.

"Not anyone you will be seeing anytime soon." Stan growled on, now placing his body in front of the doorway and the demon. Bill's eye never left him. In fact, it's stare was more intense than before.

"Stanford, I don't care what you think you're doing but you're going to tell me who those kids are and you're going to tell me right now." Bill demanded, his voice dangerously low again, causing Stan to stay where he was. Bill had already taken somebody from him once, he wasn't going to get the chance to do it again.

"Nobody you will ever, and I mean ever, get the chance to meet, Bill Cipher. You will never go near them, you will never be able to speak to them. They mean nothing to you." Stan retorted, and he almost wanted to run upstairs to see if what he was saying was true. That Bill somehow didn't escape and get to his kids. But even if he did, he wouldn't be able to see them. Or sense them, for that matter. He'd already marked them, and hid them… They had to be safe.

Bill remained frozen to the spot, and Stan was suspicious of this. Bill never stopped talking. He never stopped moving either. So why was it that he was frozen in place, unable to speak like he was before? Bill's inhuman growl brought him quickly out of his thoughts, and instantly on edge.

"You will regret this, Stanford Pines. You will regret this."

This was the last thing Stan heard as he made sure Bill was contained, and after doing that made a beeline to the door. Locking it behind him, he quickly made his way upstairs, worry etched on his face. There were only two things on his mind at the moment, and he wouldn't rest easy until he saw that they were alright.

Bill couldn't believe it. She'd actually given birth? But not to one but to two children? And from the brief memory from Fez's mind, they appeared to be twins. Or close in age. Bill had a good feeling about twins though.

What he didn't like was the fact that they were here. Right in the middle of Gravity Falls. Why did she think sending them here would be safest?! Ah, but it might have been that dastardly man's fault. Thinking such a thing. Bill briefly wondered if they were both here, but he discarded that idea with a wave of his hand. He would have sensed her, of all people.

But why couldn't he sense them?! Why did he have to find out that her children were here, right above him, for how long? He had to get to them. He had to make them his. They were almost his children, anyways. He'd watched their mother since kindergarten.

Bill groaned and wanted to bang his head against the glass. Knowing what that would lead to, and the golden wound on his hand served as a reminder, Bill refused to touch the cursed glass again. Seriously, who in the word knew how to make demon-proof glass?! And why would they do that? Demons need glass too. Humans, so very rude…

Back to the point at hand, Bill needed to reach those kids. They were practically family! Well, sort of. For him anyways. He needed that connection again, and seeing that if he can reach into Fez's mind here, he wondered if this damned glass would allow him to reach towards something he couldn't see.

It was a challenge, but Bill was not one who gave up easily. Bill sat down at the bottom on the glace container and concentrated. Closing his eye, his imaged those two children, taking their features in. The female looked so much like her it hurt bill a little, while the mail only had her eyes and hair. Bill, now being able to see them clearly, could conclude that they were indeed twins. And that they were indeed her children. Bill felt a smile tug at the corners of his mouth. Oh finally, he was one stop closer to finding her. And to do that, he needed those kids.

Mabel couldn't stay asleep for the life of her. She hated the fact that she couldn't but there was no way of her fixing things, so she might as well stop fighting a losing battle. Mable opened her eyes and saw she was holding her brother in a bear hug, literally crushing him against her. He didn't seem to mind so much, not really. His arms were pinned to his chest, and seeing that he wasn't squirming away, he wasn't totally uncomfortable.

The brown haired girl smiled at the sight, feeling almost motherly. Out of the two, Mable was the not only the oldest, but the strongest. She might not be as smart as Dipper, but she knew where and when to talk freely verses when to hold her tongue. Sadly, her brother never seemed to have learned that lesson. Which often ended with Mable beating up whoever bet Dipper up.

Maybe that wasn't the right way of doing things, but it worked for them. And Dipper was always there for her when she needed a shoulder to cry on when yet another boy broke her heart, or when she and their father got into a huge argument over something concerning Dipper or herself or the both of them. Dipper was always a calming presence to her, and she was his rock, even if he didn't say it.

So Mable grabbed onto him, and he huddled close to her. It was nice, until something of course had to ruin the sibling bonding moment.

Mable felt something, was it wind perhaps? Then she wondered why everybody thought it was the wind when they were clearly inside. But then she had done the very thing and shook those silly thoughts out of her head. It wasn't wind, she decided. It was something magical, of course. Because she couldn't go through one evening without having to deal with people trying to kidnap her or Dipper or even try to take over Gravity Falls. Was just one night too much to ask?

The girl groaned and slowly unwrapped her arms from her brother, who in turn rolled away from her. Mable stretched, stood, and followed where she thought the "wind" was leading her. She didn't know what to call it. Maybe it was a handsome prince awaiting for her?! Eager to find whatever magical creature, prince of no prince, awaited her, Mable walked faster.

It was a short, boring journey to the vending machine. What kind of ghost wanted a snack? She guessed she would do the same thing if she was a ghost, but it still annoyed her. She'd complain that she was tired, but then she'd be lying to herself. When she was about to turn around, she saw a glowing light from what looked to be behind the vending machine. Curious now, she pried the secret door open, to reveal a secret passage. Mable gasped.

"Omg this is totally wack! This needs a graveling hook." Mable whispered, sparing a glance at her brother as she bolted upstairs. Going through her belongings, and finally finding her graveling hook. She of course made she made it better, thinking a few stickers in the needed places was something that made it look better. Nothing bad could come of cat stickers.

Running back downstairs, graveling hook in hand, Mable returned to the door, and started her decent. It was a long decent, straight down. Mable stumbled a few times, she was lucky she didn't fall. She did, however, hurt her ankle after another stumble, and she knew if Dipper found out he'd keep nagging her about it until she gave in and told him about this awesome passage way. But for now, it was her little secret.

Reaching the bottom, she didn't hesitate to open the door. She had her graveling hook in hand, pointed at… a dark room. Dang, this wasn't creepy. And there was probably something totally cray cray waiting for her in that dark room. And it was probably magical.

"Please be a vampire." Mable whispered and walked into the room and searched the door for a light switch.

"Sorry to disappoint, kiddo." A voice said, causing Mable to point her graveling hook at where she thought the noise was coming from. Said voice chuckled at this. "Come now, kiddie, did you really think that little thing would stop me?"

"Where are you? Show yourself!" Mable demanded, standing her ground. She had seen far worse, whatever this things was couldn't possible make the top ten.

Suddenly all the lights were on, and a floating triangle was in the center of the room, surrounded by glass. It's one eye blinked, or was it a wink? She decided to say winked cause it made more sense.

"You're thoughts are running a mile a minute, how do you keep up?" The triangle asked, taking his hat off and fiddling with it. Mable shrugged in response.

"The sugar helps a lot."

"I bet it does."

"So what exactly are you?" Mable questioned, casually walking over to the glass and poking it with her finger. "And why are you trapped down here?"

The creature rolled his eye. "I'm Bill, the demon of dreams and of the mind. Oh, it's nice to meet you."

Mabel looked at him and shrugged. "I guess it's nice to meet you too Billy."

"Billy? Excuse you."

"What? I like Billy. Therefore you will be Billy!" Mabel declared. Bill sighed in defeat. "I'm Mabel, btdubs."

Bill looked up at her, a look of misunderstanding written on his face. "Btdubs?"

"Omg dude how out of time are you?" Mabel looked at him, hummed, and nodded to herself. "I think you'll like my brother, or hate him. But he'd be tots excited to meet you." Mabel stated, a braces-filled grin on her face. Bill stared at the strange things inside her mouth, but shook his head after a while.

"Your brother?" Bill asked, causing the girl to look straight at him. Her appearance changed from happy to serious in a matter of seconds.

"What about him?" She asked, and Bill didn't think it was wise to mess with these two. Not just yet anyway. He wanted to play with these two, but he didn't want to spoil the fun early all the same. Time would come when he could start playing for real. Now he had to wait.

"Nothing, just was wondering if he was as cool as you." Bill says, causing Mabel to laugh. Puzzled, Bill looked at her, his face reading confused.

"He's really lame, but he knows a lot about the supernatural stuff, so many he knows how to get you out of there, or maybe he knows something about you? Maybe you just need a different color… Pink! Pink would look good on you. And sparkles! Oh my gosh if Dipper can get you out I am totally giving you a make-over. Oh and give you a new—you can change colors too?! Do purple next! No, wait, do rainbow!" Mable cut off, in mid-ramble to notice Bill had changed from a bright yellow to a nice shade of pink. Bill just stared at her and started sputtering.

"Ex-Excuse ME?! I am N-NOT a play thing! I'm an all-powerful demon! You should fear me!" Bill spat out, when he was able to speak again. Mabel just giggled and twirled in a circle.

"Bill, I was almost married off to a bunch of gnomes. Your little demon rant? Or even the all-powerful one? I was expecting more from you." Mabel sighed, actually looking pretty disappointed. Bill gasped in surprise. Was this child really that much like her? Was her brother like this too? Oh this was going to be so fun!

"Well, I should probably go soon, or wake Dipper to show you…" The girl with the long brown hair stopped there, and gave Bill a hard look, before making a noise. Bill blinked. What was the noise for?

"I'll introduce you two tomorrow, I'm actually kind of tired now! So later gater! Goodnight." Mabel says, and steps out of the room. She waves and gives Bill a smile, before closing the door behind her. Without looking back, she walked up the secret passage stairs, and arrived at the secret entrance. Mabel grinned and slowly closed the door, but not all the way. Man, was Dipper in for a real treat tomorrow! She grins to herself and lays back down next to her brother, who clings to him instantly rolled over towards her. She automatically wrapped her arms around her twin and before she knew it she was in dream land.

Dipper woke up pushed against something. It was warm, but not unpleasantly so. It reminded him of when he and Mabel used to sleep in a mini dogpile when they were younger. Slowly opening his eyes, he saw a mass of pink and sparkles and knew exactly who he was pressed up to. Mabel and he must've dozed off while watching those terrible TV shows. Seriously, Gravity Falls needed better cabal.

Not daring to move until Mabel woke up, he move his head as slowly as possible to see if Grunkle Stan was still in the room. He was greeted with a giant eyeball right in his face. He had to bite into his cheeks to hold in his scream. The eye seemed to be looking for something, since he never actually made eye contact. He heard it make a humming noise.

"I know that they're in this area… Why can't I see them?" A voice groaned. Dipper tensed, and prayed that Mabel slept through this. He didn't need another incident that was like the pixies. That was a wild ride from the beginning to the end. But Dipper snapped back to reality when the eye moved to where Mabel was currently sleeping, and made a frustrated noise.

"I know they're here, but where are they?!" Dipper gulped. This eye was looking for him and Mabel? What did they do this time? Dipper didn't think they pissed anybody off… No, not recently anyway.

Dipper built up enough courage and slowly stood up, and stared at the giant eye, who was now looking intensely at the couch. Dipper cleared his throat and the giant eyeball turned towards him, a pupil trying to find him.

"What exactly are you?" Dipper asked, slowly walking away from where Mabel was if it suddenly decided to attack.

The eyeball laughed. Which puzzled Dipper, seeing as it had none. "Who am I? Who are you, little boy?" This creature asked, making Dipper roll his own eyes. Great, it was going to play this game.

"I don't have to tell you anything." Dipper replied, with fake bravo. He looked directly at the giant floating eye, and it might have been the fact that the monster couldn't see him, but he felt brave for one in his young life.

However brave Dipper felt was instantly gone when he heard the monster start to laugh. It started soft and low, which sent shivers down his spine. That laughter started to increase, until he was sure that whatever monster was in this house was shaking the walls with it's crazed laughter.

It must have shook the house, because before he knew it Dipper was on the ground next to a half awake Mabel, and with a cranky pissed out Grunkle Stan standing in front of them.

"Leave, now." Stan growled out, and the enormous eye just rolled said eye.

"I'll be waiting to talk to you two very soon~!" Was the final thing the demon said when there was a blinding light, and the demon had vanished from sight. Stan slowly turned around to face the Pine twins, who slowly met his gaze.

"Does anybody want to tell me what exactly just happened?" Stan demanded, crossing his arms. Mabel responded by standing up, stretching, and cracking her neck. When questioned by their grunkle's eyebrow, Mabel rolled her shoulders and gave him a small smile, her eyes now narrow.

"I think we need breakfast first before trading secrets, don't you agree, Grunkle Stan?" Mabel asked in her sweet voice, but Dipper knew better. Mabel was using something she knew to get answers out of Stan, and he knew it too, by the way he stood up and grumbled over to the kitchen. Mabel turned toward her brother and smiled at him, but it was less intense.

"This is it Dipper!" She softly exclaimed, grabbing onto her brother and jumping up and down. "We might finally get some answers around here!" She squealed, and hugged her brother tightly. Said brother was at loss of words, and hugged back just as tightly. If that was at all possible.

"Mabel that was amazing!" Dipper exclaimed quietly as he could when he finally found his voice. A grin plastered on his face; he was so proud of his sister, but he wasn't sure how she'd done it. She must've taken something out of those movies she watched. But right now Dipper wasn't about to complain. He was finally getting these answers, the answers he'd longed for since the day he'd arrived to Gravity Falls.

Mabel just gave Dipper a wink. "Don't worry Dippin Dots, just know that Mabel here'll always know how to handle situations from now on. Plus, if I can convince Stan into making some of his mean pancakes, then I'd withhold information every time." Mabel says, and the thought of pancakes makes both of their stomach rumble.

Grinning at her brother Mabel nudges him and challenges him to a race to the kitchen. Never one to back down from one of their sibling challenges, Dipper accepts and their off, racing toward the kitchen where Stanford Pines was making his niece and nephew some of his homemade pancakes.

Little did the Pines Family know that their peace of mind was going to be disrupted.

Mabel liked using her innocent face to get what she wanted. And right now she wanted answers. There was some creepy thingy named Bill that lived in their basement. Their secret basement. And she might have another side to her, who knows? She was told at a young age that a women should never revel too much about herself, so Mabel just didn't tell others she knew things.

Dipper knew she knew, though. Lol, that was a weird sentence. Anyways, back to the present moment. The two mystery twins made their way to the kitchen, preparing to confront their super-secretive-great uncle.

Turning toward the kitchen, Mabel saw Stan flipping jacks, and she felt her mouth start to water. Quickly shaking her head as to clear it of distractions, Mabel sat down in her chair, Dipper following his twin's lead.

Stan was quiet, which made everything tense and awkward. But Mabel didn't care; she wouldn't let a little tenseness and awkward conversations stop her. If she did, would she truly be Mabel Flipping Pines? Humming to make noise, Mabel kicked swung her feet under the table, a perfect picture of ease. Her brother, on the other hand, looked like somebody had told him to disable a bomb.

He was sweating way more than usual, and his eyes stayed glued to Stan's back. Maybe her twin thought that he could simply stare the answers and secrets out of their care giver.

When the jacks were done, the tension in the room went up in levels. Mabel didn't know why, so she frowned and made an annoyed noise in the back of her throat. That got her uncles attention, and he turned around to face the two children. A forced smile plastered on his face.

"Who wants syrup?" Stan asks, and Mabel's eyes narrowed. She was laser focused right now, not even a syrup race would distract her. And did she love winning those.

"Stan, come sit." Dipper's voice said, quiet but the command wasn't hidden. Looks like Dippin Sauce is finally in action too, thought Mabel, as their grunkle awkwardly walked over and carefully placed the jacks on the table. Unable to resist the deliciously smelling flap jacks any longer, the twins dug in.

When they were all settled, the air went back to being just as tense as it was before. Stan watched as Mabel shoved three flap jakes in her mouth, either in horror or in amazement. Dipper copied his sister, but to a lesser extreme. When all was settled and done, Mabel cleared her throat.

"So, Grunkle Stan?" Mabel asked, her voice croaking slightly. Stan frowned, maybe hoping that Mabel would have forgotten. Dipper's face was set in a determine look, but it might have been ruined with the bits of syrup and crumbles of flap jacks covering his face. Mable had the same issue, but she could let Waddles lick it off later. Business time was now time.

"Kids, I think it's about time we talk about family history. There's a few things I need you two to understand first." Grunkle Stan started, shifting in his seat. "You two better get comfortable. It's going to be a while." With a deep breath, the two twin's great uncle began to tell them everything.

How was that? I hope you enjoyed! It's a long piece of work lemme tell you. With school and everything I finally found a place and time where I can work on this! YaY! Meaning: Hopefully more chapters!

Please R&R~! It means a lot and is great encouragement.

See you, little devils~!
