Well guys, this is the first chapter of Sebastian in Gravity Falls taking care of his nephews. You said you would like to see a parallel story as I finished his backstory and how he ended up in GF, so here it is!

As the story continues, this one and The life of SP, there will be mysteries you will not know until its answer is released as a chapter in his life, so you will be able to make theories and speculate, hehe.

ANOTHER THING! I MADE AN INTRO FOR THE STORY, AS IF IT WAS A SERIES, SO I WOULD LOVE IT IF YOU CHECKED IT UP IN YOUTUBE! I SPENT WWAAAAYY TOO MUCH TIME ON IT AND I WOULD LOVE TO HEAR WHAT YOU THINK OF IT! THE NAME IS GRAVITY FALLS INTRO: Fanmade Animatic. Username: Lorena Pacora


Ahh...Summer time!

It is a nice time for leisure, recreation, and taking 'er easy...

Unless you are a Pines...

A blond and brunet curly man screamed along 2 brunet kids as their golf cart crashed through a giant "Welcome to Gravity Falls" sign.

The blond man screamed even louder when he and the girl looked backwards and saw that the monster chasing them was stepping on their toes.

"It's getting closer!"

"No kidding, Shooting star!"

The car flew and landed roughly. Fortunately for them, it continued working.

The blond roared at the monster, shooting at it with a gun.

He glanced at the kids. The one shrieking like a little girl was his nephew Dipper and the girl about to puke was his niece Mabel...He wondered why he accepted doing this! He was a terrible babysitter! Just look! They were in a damn golf cart fleeing from a creature of unimaginable horror! Just because he couldn't keep them safe!

'Useless'

The monster threw a tree in their path and uncle and nephews screamed.

"Look out!"

Well, there's a perfectly logical explanation...

Everything was Sherman's fault!

-.-

Sebastian opened his car's backdoor for the deadly silent and pale kids he had to watch ALL summer.

Damn Shermie and his begging voice. The little shit knew he could never say no to him!

"Ok, listen here little pests, I know we started kinda bad but I need to get to work now!" he said and the boy snapped.

"Kinda bad?! You almost crashed into a tree! TWICE!" He screamed at his uncle wearing a yellow vest and a black triangular eye-patch.

"Oh come on, Mason, give me a break!" Seb huffed, looking at them but receiving a deadly glare from him.

"Don't call me that" the little boy huffed while his sister tried to calm him down. "It's Dipper"

"Ok Pinetree" Sebastian smiled and laughed when the boy shrieked. Oh, how much he will love bothering Pinetree all summer!.

"I didn't want to be here!"

"Well, I didn't want to have you here either but here we are!" Seb said with a big forced smile.

Stupid Shermie sending his stupid kids here!

And his kids weren't just any kids...

They were Shooting Star and Pinetree...

The moment he saw them at the bus station an unexplained anger surged inside him and he frowned at his own reaction because he didn't know these kids! He didn't know why he felt like he hated them with all his might! They weren't Filbrick!

Bill2 was taunting him, telling him through giggles to try and remember the kids, that he would be surprised.

He started driving and out of the blue memories flashed behind his eyes. Without realizing, he was screaming, driving directly to a tree as the preteens screamed for their lives.

Then he threw up. He was related to those damn kids!

Mabel looked between her brother and uncle and sighed before smiling. This was her last summer vacations as a child and she wanted it to be the best one ever!

"Uncle Sebastian, don't mind Dipper" She giggled and hugged her twin. "He is grumpy because Dad didn't let him bring his videogames. We will have the best summer EVER!" The hyperactive girl screamed and Seb smiled slightly.

"Good, Shooting Star" he rolled his eyes and picked up one of her many bags. "Move, I'll show ya your rooms"

Dipper glared at the blond, not trusting him a tiny bit and followed him inside by the door saying 'Gift Shop'

"Welcome to the Mystery Shack!" Seb smiled, opening his arms. "It is the best Roadside Attraction in the state!"

"You mean a tourist trap" Dipper crossed his arms, glaring, and Sebastian glared back.

"Yeah! And it is really awesome dudes!" The twins jumped at the voice and saw a chubby man with a green tshirt and a cap.

"Soos, the brats. The brats, Soos" Seb smiled as Dipper glared at him. Sebastian only laughed. Oh it was hilarious! He loved how adorable he looked wrinkling his nose like that!

"He is my business partner and friend! He helped me built this piece of crap with his bare hands!" Seb grabbed Soos's hands with his gloved ones and Dipper frowned. Was it him or he had 11 fingers?

"Got a problem, Pinetree?" Seb asked and the kid shook his head. "Good! HEY RED! BRING YOUR ASS OVER HERE!" The man shouted and the twins looked at each other.

"Uncle Sebastian...you cursed" Mabel said, mildly horrified as her uncle looked at her.

"And?"

"Dad says it is wrong"

Sebastian burst into uncontrollable laughter as a readhead teenager appeared complaining.

"Your dad curses worse than a sailor, What he is, sweetie, is a hypocrite" he smiled sweetly.

Mabel pouted and went to explore around as Dipper examined his uncle. His parents had told him he was exccentric but Sebastian was nuts!

"This is Red or Ice. Call her whatever. She is a lazy girl who should be in the cashier not somewhere else lazying around"

Dipper felt his cheeks warming up slightly.

The teen smiled. "What's up? I'm Wendy, actually. Mr. P likes to give everyone nicknames"

"Not everyone, Red. Just special people" he winked. "Go to work, now" he snarled menacingly and she went back to the cashier rolling her eyes, not intimidated by her crazy boss.

A loud scream was heard and Dipper and Seb looked at each other.

"Oh dear...Hope she is not dead" Seb mumbled as Dipper dropped his stuff to look for his sister.

"Mabel?! Mabel! Where are you!?" The boy shouted, noticing Seb was with him too.

Sebastian sighed in relief when he found Mabel in his sewing room. When they entered, Dipper immediately asked the girl if she was hurt.

"Dipper! OMG! Uncle Sebastian, you make clothes?!" She ran to examine the mannequin and cooed at the pink dress which was being made.

"Um..." Seb pursed his lips. "Yeah, why would I have this or the store on the other side of the Shack if I didn't?"

Mabel gasped and screamed again. Seb enjoyed how excited she was.

"Uncle Seb! I make clothes too! I made this sweater!" She showed it to her uncle. "I make lots of sweaters! Right, Dipper?" She looked at her pouting brother and he nodded absentmindly.

"Uh huh"

'Hate them! It was their fault! Everything is their fault! You are a pathetic human because of them!'

Seb's anger decreased a bit, much to his inner demon's anger. She liked what he did! Now he disliked the girl much more less.

"Well, that is extremely awesome, Shooting Star!" He knelt and examined her work. "Um...The knitting is still kind of rough but that's ok, I was like you at your age" he reassured and laughed when Mabel screamed and hugged his waist.

"Teach me!" She demanded.

"Sure. But first go leave your stuff to your room" he patted her long hair.

"Move, broseph!" Mabel grabbed Dipper's hand and dragged him upstairs to the attic.

When they brought all their bags upstairs, Dipper scanned their room with a grimace as his sister hanging up posters of her favorite bands all over her side.

"Why did he send us to an attic? Who sleeps in an attic anyway?" Dipper huffed.

"I think it is awesome! Look at my splinters!" Mabel giggled and Dipper grimaced even further. He backed up to his bed.

"And...there is a goat on my bed" he sighed in defeat. The animal started biting Mabel's sweater and his way-too- optimist sister giggled.

"I know you tend to-SHOO, GET OUT OF HERE!-look at the bright side of things but I don't trust Sebastian..." Dipper looked around to see if the door was closed.

"I like him!"

"Mabel! Sebastian is weird! Weirder than what Dad described!"

"I think he is awesome! He is a professional designer! Didn't you see?! And he is going to teach me how to knit even better and I like his eyepatch" mabel booped his nose and he swatted her hand away.

"Well, I don't trust him, he is weird and mean and I won't like here it, ever!" Dipper huffed childishly and crossed his arms, looking away from Mabel.

The girl sighed and went to continue decorating her side of the room. She knew Dipper was having a hard time getting use to their new surroundings but he will like it! She knew he will!

On the other side of the door, Sebastian rested his forehead against the door, breathing in and out heavily. He blinked quickly to clean his blurry sight. Wow...Maybe he exaggerated a bit too much with the teasing...Was he too mean to Pinetree?...Now he hated him...

'So dumb...you see? You can't be good, you will never be good...Kill them'

No.

Sebastian decided it was better to talk to them later, rules will be established in this house, but...not now, not when Pinetree was hating his guts ...He looked around in case someone was there and a blue fire appeared in his left hand. He drew a protection symbol on the door to keep any magical or supernatural creature out and went back to the shop...

-.-.-

A few days passed and Dipper was bored as heck in the Shack, wishing he was back home. Mabel was entertaining herself in the clothes' store their uncle owned and thinking everything would look better with glitter on them. Her twin was stuck sweeping the gift shop.

Apparently, mom and dad sold them as slaves to their demon uncle for two months in exchange of going to vacations alone...

The boy was sure as hell something wasn't working quite right in his mind...Last night he saw him walking around with a fork incrusted in his hand...and talking to himself...

Dipper looked at his uncle who was leading a groups of tourists to the gift shop. He had scared him dear with a monster mask in the morning and the man just laughed at him! Why was he so mean to him?!

Dipper narrowed his eyes at the dumb tourists. Why anyone came to see these fake attractions anyway? It was beyond him.

"Ladies and gentlemen, behold! The Sascrotch!" Seb pointed to a Sasquatch wearing underwear. That had been Soos' idea.

The tourists started speaking excitedly, and snapped pictures.

Mabel appeared from the clothes store with hundreds of dresses on her arms. "Can I try them on, Uncle Seb?!" She squealed.

Seb gasped and snatched them from her. "No touching the merchandise, Shooting Star!" He hit her head softly with his cane and showed her his fangs. The girl laughed unconcerned and ran away.

The morning turned into evening and while Dipper cleaned a jar, Mabel was hiding behind bobbleheads, squealing.

"He's looking at it! He's looking at it!" The girl whispered and her twin looked at the boy holding a note.

"Do you like me? Yes? Definitely? Absolutely?" He looked around confused.

"I rigged it!"

Dipper rolled his eyes. "Mabel, I know you're going through your whole 'Boy Crazy' phase, but I think you're kind of overdoing it with the 'crazy' part"

"What?!" She cried and blew a raspberry. "Come on, Dipper! This is our first summer away from home! It's my big chance to have an epic summer romance!"

"Yeah, but do you need to flirt with every guy you meet?"

Mabel crossed her arms and huffed. "I don't do that"

"Oh yeah? What about that boy you scared in the shop and shoved him to the floor? The turtle boy? Even that teenage boy from Mattress King!" Dipper laughed. They went to buy a new mattress because his was damaged and Mabel scared the life out of the poor guy.

"Mock all you want, brother, but I got a good feeling about this summer!" Mabel smiled. " I wouldn't be surprised if the man of my dreams walked through that door right now" she pointed at the door.

Sebastian ran inside screaming loudly, his hands were on fire and he ran around in circles "SOOS! Help! It happened again!"

The girl winced "Aww! Why!"

Dipper would have laughed if this wasn't too weird. Soos appeared with an extinguisher and turned off the fire in their uncle's hands.

Dipper really wished he was imagining everything...because his hands weren't hurt or burnt at all...

When Seb finished screaming he ran a hand through his hair and looked at his nephews.

"All right, all right, listen squirts. See those signs on the table? I need someone to go hammer them up in the spooky part of the forest"

"Not it!" "Not it!" The twins said quickly.

"Uh, also not it" soos said.

"Nobody asked you, Soos" Seb raised an eyebrow.

"I know, and I'm comfortable with that" he pulled a chocolate bar from his pocket and started eating.

Seb groaned loudly. "Red! I need you to put up this sign!"

The redhead pretended to reach the signs as she read her magazine and surrendered. "I would, but I, ugh, can't, ugh, reach it, ugh..."

"I'd fire all of you if I could" The blond man pinched the bridge of his nose. "All right...let's make it... eenie, meenie, miney... YOU" he pointed at Dipper and the boy groaned.

"Aw, what?! Uncle Seb! Whenever I'm in those woods, I feel like I'm being watched!" Dipper winced.

"Kiddo. Not again..." Seb warned.

"I'm telling you, something weird is going on in this town. Just today, my mosquito bites spelled out 'BEWARE' "

"No. That says bewarb" Seb smiled and the kid scratched it sheepishly. "Look, kid. The whole 'monsters in the forest' thing is just local legend, drummed up by clever handsome guys like me to sell merch to guys like...that" he motioned to a fat, sweaty man who was laughing while looking at one of Seb-bobblehead's head bobble.

"So quit being so paranoid!"

'You have the right to tell Pinetree that? Geesh what a hypocrite"

Shut up!

He angrily shoved the signs to Pinetree and went to his study. "Soos. Your turn to be Mr. Mystery" he threw him an eye-patch and his cane. "Don't bother me unless someone's dying..."

"I'll go for a walk, Uncle Seb" Mabel informed her uncle.

"Yeah, don't let a monster eat you" He winked.

Dipper rolled his eyes, grabbed the signs and stomped off the shack, while Mabel waved and left, probably to the cemetery.

Seb locked the door of his sewing room and pulled off his eye-patch to scratch his yellow eye. He glanced at the table he had burnt. He really should be careful when getting angry. Controlling his flames was still difficult for him...And since the kids arrived, he had been losing control pretty easily. Damn kids...

He opened one of his notebooks and looked at the designs he should be doing. Mrs. Northwest had requested yet another dress and he really should be working on it.

As he cut the fabric, he started musing his situation. He couldn't tell them anything though...It was dangerous for them to know, and he didn't want to traumatize his brother's children telling them he was a demon...No. He just needed to hide his powers from them for 2 months.

Soos thought it was a bad idea but he wasn't the one able to combust spontaneously! Soos was his friend but he really didn't understand...No one did.

Almost an hour passed as Seb worked on the first part of the dress when he heard the front door open. It better be Dipper with all the signs gone...

He stood up, stretched with a loud moan and went to look if his nephews weren't missing any limb.

He heard voices coming from the living room. He frowned and stopped to hear.

"And get this! After a certain point, the pages just.. stop, like the guy who was writing it... mysteriously disappeared..." That was Dipper...What was he talking about?

The doorbell rang and Seb frowned.

"Who's that?" Dipper wondered.

"Well, time to spill the beans... !" she knocked a can of beans on the table and Seb stiffed a giggle. The girl was amazing.

"This girl's got a date! Woot woot" She fell backward into the chair, giggling.

Seb's smile disappeared. She WHAT?!

"Let me get this straight: in the half hour I was gone, you already found a boyfriend?" Her twin asked increduously.

"What can I say? I guess I'm just IRRESISTIBLLLLE!" She said, playiing with her sweater's sleeves. Then the doorbell rang again. "Oh. Coming!"

Seb tried to see what Dipper was reading and casually approached.

"What'cha reading there, Pinetree?"

The boy nervously hid it (he said a bit of red on the object) and the child quickly grabbed a magazine.

"I was just catching up on, uh..." he saw the cover of the magazine. "Style plus fashion equals fabulous?"

"That's a good issue"

"Hey, family!" Mabel appeared with a dark figure next to her. "Say hello to my new boyfriend!"

"'Sup?" The dark figure saluted.

Dipper frowned. "Hey..."

Seb glared at the figure. This wasn't right. He could feel it. "Yeah..."

"We met at the cemetery... He's really deep" Mabel smiled and touched his arm. "Oh. Little muscle there. That's...what a surprise..." She smiled.

Seb stuck his tongue out with disgust. Mabel was just a little girl! She couldn't have a boyfriend! Not under his watch!

"So, what's your name?" Dipper asked.

"Uh. Normal... MAN!" The man shouted. Both male Pines frowned even more.

"He means Norman" Mabel clarified.

Are you bleeding, Norman?" Seb asked with a raised eyebrow. Dipper looked up at him with his eyes slightly wide. He was about to ask that.

Norman looked nervous "It's... jam!"

" I love jam! Look. At. This!" Mabel gaped.

"So, you wanna go hold hands or... whatever?" Norman asked and Mabel giggled madly.

"Oh, oh, my goodness!" The girl giggled. "Don't wait up!" She ran away. orman followed her but ran into the wall several times before going out.

"I don't like him" Seb growled and Dipper had to agreed with his crazy uncle.

"Yeah...Me neither...There is something...not right about him!"

"Ya know what I think?" Seb sat down on the couch's arm next to his nephew. "He is a bunch of gnomes. Those little pests tend to do that to kidnap-" he was interrupted by Dipper's laughter.

"Uncle Seb! That is sooo absurb! Besides, those don't exist...do they?" He asked with a raised eyebrow. Seb coughed and laughed awkwardly.

"HAHA! WHAT?! NO! I was kidding HAHAhaHaHa!" He ran away, slamming against the wall twice before disappearing.

Stupid, stupid, stupid!

Dipper rolled his eyes and left to the attic, using his vest to hide the red journal he found in the woods...

Seb ran to the store, he was safe from spilling too much about this town here, and watched the tourists happily spend their money here. The tourist trap and the gift shop had been the best ideas Soos had had, it was incredible how much money they got everyday from lying to costumers!

Now he understood why mom did it...

Meanwhile, Sebastian's nephew was having a panic attack. "ZOMBIE!" He shrieked.

Dipper was so scared for Mabel. The journal had a page describing zombies and everything added up! The pale skin and bad attitudes! tt said they were mistaken for teenagers! And Norman looked like a teen!

Dipper looked at the window to see Norman walking towards Mabel with outstretched arms while moaning.

"Oh, no! Mabel! No, no, Mabel, watch out!" Dipper hit the window frantically. Norman put his hands around Mabel but it ended up been a flower necklace.

Dipper sighed in relief and ran a hand through his hair. "Is my sister really dating a zombie, or am I just going nuts?" Dipper asked himself alone in the attic.

"It's a dilemma, to be sure"

Dipper gasped and saw Soos screwing a lightbulb. He wasn't alone apparently.

"I couldn't help but overhear you talkin' aloud to yourself in this empty room" The man said.

"Soos, you've seen Mabel's boyfriend. He's gotta be a zombie, right?" Dipper looked up at the man, who made a thinking face.

"Hmm. How many brains didja see the guy eat?" Soos asked.

Dipper looked down, biting his inner cheek. "Zero..."

Soos sighed. " Look, dude, I believe you. I'm always noticing weird stuff in this town..." Closer than you would think, was unsaid. "Like-Like the mailman? Pretty sure that dude's a werewolf"

Dipper remembered the hairy man and remembered thinking the same.

"But ya gotta have evidence. Otherwise, people are gonna think you're a major league cuckoo clock" Soos finished.

"As always, Soos, you're right" Dipper stood up.

"My wisdom is both a blessing and a curse..." The chubby man said dramatically.

"Soos! The toilets are clogged again! And as hell I will do it with my nails painted!" Sebastian shouted from downstairs.

"I am needed elsewhere"

Dipper watched Soos dissapear and started his plan. He was right. He needed evidence and he was determined to get it! He went to his room, grabbed his camera and ran away to stalk his twin and her boyfriend! It wasn't creepy at all!

He followed them everywhere. First they went to the park. Mabel threw a frisbee at Norman but he couldn't catch it and fell over. Then Norman broke a door window to open it from the inside and letting Mabel inside the diner.

Norman waited till she was inside to follow her stumbling around.

Dipper followed them as they romantically skipped around holding hands whens suddenly Norman fell to an open grave and crawled out with his hand first.

He returned to the shack with enough evidence. He had seen enough...

-.-

Dipper burst into the room as Mabel brushed her hair.

"Mabel. We've gotta talk about Norman" Dipper demanded.

"Isn't he the best? Check out this giant smooch mark he gave me!" She showed him her cheek which had a giant red spot on it.

"AaAaHH!" The boy screamed horrified.

"Ha, ha! Gullible" Mabel grinned. "It was just an accident with the leaf blower!"

"What were you doing with the leaf blower?!" Dipper sidetracked.

"Uh...Kissing practice? That was fun" The girl smiled and Dipper sighed, completely imagining his sister with the leafblower on her face.

"No, Mabel, listen! I'm trying to tell you that Norman is not what he seems!" He showed her the journal.

Mabel gasped and smiled. "You think he might be a vampire?! That would be so awesome!"

"Guess again, sister. SHA-BAM!" He held the book open in the wrong page.

Mabel grimaced at the gnomes page. "Ew!"

"Oh, wait. I'm-I'm sorry..." He searched for the correct page and then showed it to her. "Sha-bam!"

"A zombie? That is not funny, Dipper" the girl crossed her arms.

"I'm not joking! It all adds up: the bleeding, the limp. He never blinks! Have you noticed that?!"

Mabel thought about it for a second. "Maybe he's blinking when you're blinking..." She tried to reason.

Dipper couldn't take it anymore and started shaking her. "Mabel, he's gonna eat your brain!"

The girl angrily pushed him away. "Dipper, listen to me. Norman and I are going on a date at five o'clock, and I'm gonna be ADORABLE" She poked his chest. "-And he's gonna be DREAMY!" She pushed him out of the room.

"Bu-bu-but—"

"And I am not gonna let you ruin it with one of your crazy CONSPIRACIES!" She slammed the door and Dipper sighed defeatedly as he slid and sat on the floor.

"What am I gonna do...?" He asked to himself.

He went to the living room and sat down on the couch to rewind what he recorded about Norman.

"What's up with the long face, kid?" Dipper jumped startled when he heard the voice of his uncle. The man sat down on the arm of the couch.

"Shouldn't you be with the tourists?" The pre-teen asked half annoyed. He wasn't in the mood to tolerate his uncle's teasing. He already received that a lot in school...

Sebastian snorted at the suggesiton "And having to be with those dumb idiots?! No thank you. I have Soos for that" He smiled, remembering seeing Soos explaining with his infinite patience the rock face to those idiots. He would have hit them with it. He took a sip of his martini. "Want some?"

"No, I can't" Dipper said confused.

"It doesn't have alcohol...but alright" Seb said. "So, what are you doing?"

"Well..." Dipper sighed defeatedly. "I thought Norman might be a zombie...but...I don't really have real evidence..." He showed him what he recorded and ignored Sebastian's question of 'You followed them around all day?'

Dipper spoke when the video changed to Norman hugging Mabel "I guess I can be kind of parano-"

Suddenly, Sebastian spat all of his drink to a side and the two male Pines screamed.

"WAIT WHAT?!" Dipper shouted.

"PLAY IT AGAIN, DIPPER!" Seb shouted.

Dipper did as asked and indeed. Norman's hand fell off and he picked it up...

The two screamed and both fell backwards of the couch.

"I WAS RIGHT, OH MY GOSH! UNCLE SEBASTIAN, MABEL IS IN DANGER! UNCLE SEB!" Dipper shook him as hard as he could but Seb didn't even move.

"What do we do?!"

"We will save her, don't worry, kid" He quickly went to another room and Dipper followed him nervously.

"Uncle Seb! What are you doing?!"

"Calm down a fucking sec, kid! Geesh!" Seb rolled his eyes and from under the kitchen stool he pulled out a bag. He opened it and Dipper saw it was full of guns and weapons.

"Do you have permission to have that many weapons?"

"As a wise soul told me once...When there are no cops, everything is legal, wink!" he winked as he grinned. "You probably didn't notice but I am winking" Seb threw him a baseball bat and Dipper barely caught it.

Seb grabbed two guns and told Dipper to follow him. They ran past the crowd of tourists looking at the rock that looked like a face and saw Wendy arriving in the golf cart.

Dipper ran toward her and frantically exclaimed. "Wendy! Wendy! We need to borrow the golf cart so we can save my sister from a zombie!" He screamed, moving his arms frantically.

Wendy smiled at Dipper and looked up at her boss, who was nodding as scared and vigorously. She gave the keys to Dipper and went inside the shack.

"Try not to kill any pedestrians, Mr. P." Wendy said as the two got in, Seb driving.

"I DON'T PROMISE ANYTHING!" He snatched the keys from his nephew and both got in. He pressed the gas and sped up to the forest.

"Don't worry, Mabel! We'll save you from that zombie!"

"Shooting Star! Your brains aren't going to get eaten today!" Seb screamed to the air.

Dipper was so surprised Sebastian believed him so quickly, when he was the first one to tell him there was nothing weird with Gravity Falls...Maybe it was just the crazy part of him? He was about to ask when they heard screams.

"Help me!" That was Mabel.

"Mabel!" They both said and Seb followed the sounds of the screams.

Seb was biting his lip nervously. What would he tell Shermie if one of his kids was eaten by a damn zombie?! He would kill him!

"Hold on!" Dipper shouted. "Faster, Uncle Seb!"

The forest turned more bluish as they approached the screams. It was beautiful but neither of them could appreciate it because Mabel was just there! And uneaten!

"The more you struggle, the more awkward this is gonna be for everybody! Just, ha ha, okay. Get her arm there, Steve!" The creature said and both uncle and nephew frowned.

"Let go of me!" Mabel punched the small creature off. He bounced around, stood up dizzily and puked a rainbow.

Seb and Dipper got out of the cart and Dipper exclaimed.

"What the heck is going on here?!"

A gnome hissed at them and Seb and Dipper flinched away slightly.

"Ew!" Seb grimaced.

"Dipper!" Mabel shouted. "Norman turned out to be a bunch of gnomes! And they're total jerks!" A gnome pulled her hair and she winced. "Hair! Hair! Hair!" Seh winced.

"HA! I TOTALLY TOLD YOU THEY WERE GNOMES!" Sebastian exclaimed, poking the child in his chest. Dipper looked at him weirdly and he coughed awkwardly. "Sorry"

"Gnomes? Huh, I was way off..." Dipper wanted to take the journal out of his vest and read about them, but...could he trust Sebastian with the secret?

Sebastian stepped in front of them. "Hey! Jeff!" He called and the younger gnome looked at him and gasped.

"Se-Sebastian..." Jeff walked toward the human adult as he glared.

"You know them!?" Dipper gaped.

"Let my niece go, you idiot before I roast you alive" his eye turned red under the eyepatch and as any supernatural creature from the forest, they felt the masive and familiar power he had.

They had since he came to town...

The gnomes managed to tie Mabel to the ground as they talked. "Li-Listen...Ha ha... Um, you know, this is all really just a big misunderstanding! You see, we didn't know she was related to you..."

"Let her go" Seb repeated, his hands were feeling warmer but he couldn't! Don't let them see, Sebastian! You will scare them for life!

"But I can assure you she is not in danger!" Jeff exclaimed happily. "She's just marrying all one thousand of us and becoming our gnome queen for all eternity! Isn't that right, honey?"

"You guys are butt-faces!" Mabel shouted at the gnomes holding her down and one covered her mouth.

Seb growled. No, no! Control yourself! The kids are here!

Dipper grabbed his baseball bat and pointed it at Jeff. "Give her back right now, or else!"

"You think you can stop us, boy? Not even your uncle can against us! You have no idea what we're capable of. The gnomes are a powerful race! Do not trifle with the-"

Dipper casually hit him with the bat and he flew away.

"AH!"

"HAHA! Good thinking, Pinetree!" Sebastian laughed as he kicked the gnomes around Mabelwith his feet to freed her.

Mabel ran away and the three of them ran toward the golf cart.

"He's getting away with our queen! No, no, no!" Jeff shouted.

Dipper was the one to drive this time. Mabel sat next to him and Seb jumped to the back space where he left his weapons. He would see purple blood today!

"Seatbelt" Dipper said.

"FUCK SEATBELTS, PINETREE MO-AAAHH!" The man was taken off guard when Dipper backed up and drove away.

"You've messed with the wrong creatures, Cipher! Gnomes of the forest ASSEMBLE!"

Luckily none of the Pines was there to here that...

Seb loaded his gun and was ready to defend his nephews in case they were back.

"Hurry, before they come after us!" Mabel cried.

"I wouldn't worry about it. See their little legs? Those suckers are tiny!" Dipper laughed.

"Uh...Pinetree..." Seb said and Dipper stopped the cart.

There was a stomping sound and they saw a giant monster thing, all the gnomes were stacked up forming a huge gnome.

"Dang" Mabel muttered.

"All right, teamwork, guys. Like we practiced!" They heard Jeff shout from the top of the gnomes and they growled.

"Move, MOVE!" Mabel and Seb shouted at the same time.

Dipper drove the cart away just as the gnomes smashed their arm down and it broke down. The gnomes ran back to their position and they started following the Pines again.

"Come back with our queen!"

"Uncle Seb! I don't want to marry those gnomes!" Mabel whimpered.

"And you won't, sweet pea" Seb loaded his guns and started shooting at them with both hands but the gnomes just moved from their position a little bit and dodged the bullets.

"Darn it!" Seb cursed.

"It's getting closer!" The girl screamed.

The gnome giant threw several gnomes at them and showing them their fangs, they started chewing the cart and hitting them with tiny fists.

Seb growled too, his fangs on view and bit the little arm of the gnome who tried to touch him.

The gnome cried in pain and fell from the cart. Seb smiled and licked the blood off.

"Hey! Their blood tastes like blueberry!" He exclaimed with a huge smile.

"NOT THE TIME TO TASTE GNOME'S BLOOD, UNCLE SEB!" Dipper cried in a mix of horror and confusion.

Mabel punched the gnome hanging from the carts roof and it fell.

Shmebulock jumped up behind Dipper, but he quickly grabbed him and slammed him into the steering wheel out of annoyance. He threw him out but another gnome jumped onto the cart and started clawing Dipper's face.

"Aaaahh!" The boy cried.

"I'll save you, Dipper!" Mabel exclaimed and repeatedly punched the gnome off of Dipper's face until it fell off with Dipper's hat.

Dipper was dizzy from the punches, slightly bruised too, but managed to smile. "Thanks, Mabel..."

"Don't mention it" She said.

Gnome Giant roared, he picked up a tree and threw it at them.

Sebastian shrieked a high pitched scream.

"Look out!" Mabel cried.

The three Pines screamed loudly as the cart overturned and landed next to the Mystery Shack.

Seb groaned and put his six fingered hand over his forehead. "Are you alright...?" He asked his nephews as they crawled out of the cart.

The twins nodded but gasped when they saw Gnome Giant getting closer.

"Stay back, man!" Dipper threw his bat at the gnome giant but they easily crushed it with their giant fist.

Mabel and Dipper hugged each other and Seb hugged them, shielding them from the giant.

"AAAHHHH!" They screamed.

"Soos! A little help here!" Seb screamed.

His assistant was in the shack with some tourists, wearing an eyepatch.

"Look dudes! The world's most distracting object!" The tourists were amazed, looking at it turn and turn.

"Just try to look away, you can't! I... can't even remember what I was talking about..." Soos muttered.

The giant gnome approached the Pines and they started walking backwards. Dipper was shielding Mabel and Seb was with his arms spread over his two nephews.

"It's the end of the line, kids! Mabel, marry us before we do something crazy!" Jeff threatened angrily.

"No, no, No! Shooting Star, there's gotta be a way out of this!" Seb grimaced.

Mabel made a determined face and stared at the monster. "I gotta do it..."

"What?!" Her brother shouted. "Mabel, don't do this! Are you crazy?"

"Mabel, no!" Sebastian said sternly. "What will I tell your parents?!" He asked worriedly.

"Trust me" the girl said and the male Pines blinked, surprised.

"What?" Both said at unison.

"Uncle Seb! Dipper, just this once. Trust me!"

Seb looked at her niece and sighed before nodding. "I trust you"

He stepped back as Dipper looked at him surprised and shocked. He glanced at gnomes, then at Mabel and finally stepped next to his uncle.

"I trust you, Mabel"

"All right, Jeff. I'll marry you..." the girl said and the gnome smiled widely, quickly climbing down the giant gnome.

He approached Mabel and held out diamond ring. "Eh? Eh?"

Dipper watched grimfully as Seb watched confused. What was Shooting Star's plan?

Mabel smiled and held out a hand for Jeff to put the ring on her finger.

Jeff gladly put the ring on her finger and smiled. "Bada-bing, bada-bam! Now let's get you back into the forest, honey!"

Dipper was about to step between them when his uncle stopped him with a smile. Mabel was grabbing the leaf blower...

"You may now kiss the bride!" She said with fake happiness.

"Well, don't mind if I do!" Jeff said and leaned up to kiss Mabel.

The girl quickly turned on the leaf blower.

"Ah! Hey, hey, wait a minute! Whoa, whoa! Wh-what's goin' on?!" He was sucked half-way into leaf-blower and started thrashing.

"That's for lying to me!" She screamed and increased the sucking power. "THAT'S for breaking my heart!"

Seb and Dipper laughed when the gnome was sucked even more. He looked so funny!

" Ow! My face!" The creature whined.

"And THIS is for messing with my family!" She aimed Jeff at the Giant gnome and Dipper ran next to her as Seb watched with a smile and with his arms crossed.

"Wanna do the honors?" Mabel asked her twin and the two aimed at the monster.

"On three!"

"One, two, three!" They blasted Jeff towards the gnome monster and it exploded, making the gnomes fall from the sky.

Seb ran toward his laughing nephews who were thrown back to a pile of leaves.

"You alright, kiddos?" He helped them stand up and they laughed.

"Yeah!" They said at the same time.

Mabel gave the leaf blower to her uncle for him to have fun too and he started running around laughing, blowing scared gnomes off his front yard.

"HAHA! TAKE THAT!"

He saw Gompers pick a six-pack holder up with a gnome trapped there and ran off.

Seb turned it off and looked at his nephews with a huge smile on his face, showing off his fangs.

"Look at the bright side" Dipper was telling his crestfallen sister. "Maybe the next one will be a vampire!" He smiled.

"Oh, you are just saying that..." Mabel giggled, feeling already better.

"Awkward sibling hug?" Dipper suggested with his arms spread.

"Awkward sibling hug" Mabel replied.

The kids hugged each other and then patted their backs. "Pat, pat"

"Kids...That...was...AWESOME!" Sebastian exclaimed laughing. "Best! Adventure! Ever!" He screamed excitedly and his nephews laughed.

"That was brilliant, Shooting Star! I guess we could say leaf blowers are their weaknesses, right Pine Tree!?" He looked at the boy and he nodded quickly.

"Ye-Yeah..." Dipper stuttered. He had never seen Sebastian this happy.

"You saw the size of that thing?! For a second I thought it would catch us! But man! Then the cart was like Woosh! And we were flying and then-! " Seb stopped his rambling and laughed awkwardly. He straightened his suit, adjusted his eyepatch and ran a hand through his now disheveled blond hair.

"Le-Let's go inside!" Seb ruffled their hair to clean their curls from the leaves on them.

Mabel giggled and followed her uncle as Dipper chuckled and rolled his eyes.

Maybe...Sebastian wasn't as bad as he thought...

Sebastian opened the door leading to the gift shop and his tired but smiling nephews entered. Sebastian looked at himself in one of the mirrors of the shack and laughed.

"God, we look as if we got hit by a bus or something! That would be cool" He said.

The twins blinked confused.

"Guys, you know what?! I'm feeling EXXTREEEMLY generous today! Haha! Go on! Pick anything from the shop! It's on the house!" The blond man offered with a huge smile.

The twins smiled at that and started looking around the gift shop for something they liked.

Sebastian's eyes widened when Dipper grabbed a blue pine tree hat from one of the shelves. He had been selling those hats for a decade and he had never recognized it...

"Hmm. That oughta do the trick!" Pinetree smiled.

"And I will have a..." she grabbed an item from a box and dramatically showed it to her family.

"GRAPPLING HOOK!"

"That's nice!" Seb smiled.

"Yes!" Mabel fired the grappling hook up at the ceiling, and it pulled her up, knocking an entire shelf of souvenirs.

She laughed and then jumped back to the floor to hug her uncle.

"Thank you, Uncle Seb! You are great!...Grunkle Seb!" Seb hugged her back but raised an eyebrow at how she called.

"what?"

"It is a combination between great and uncle! Because you are awesome! Grunkle Seb!" Mabel giggled.

Dipper laughed and nodded. Well...He guessed the man bit a gnome and THAT was great!

Seb's breath hitched and he felt his eye watering. They...They thought he was...great?

He sniffed and let her go. "Ok you two, go clean yourselves! You smell like moss and dirt! You know the rules! If you don't take a bath, you sleep outside with the wolves!" He smirked.

-.-

Mabel and Dipper were getting ready to sleep. They were wearing their Pj's and for the first time since arriving to Gravity Falls...they felt happy.

Dipper was writing on his new journal while Mabel jumped on her bed, laughing, when they heard someone knocking.

"Come in!" They shouted.

Their uncle, wearing a white t- shirt and yellow shorts entered and the twins watched him sit down next to Dipper.

The preteen quickly hid his journal under his pillow and Mabel got out of her bed to join them.

"I...I came to say goodnight..." Seb trailed off and looked at their light brown eyes. He took a mouthful of air before continuing. "Look...I know we started with the wrong foot...I am a huge jerk and-and I am terribly bad at being a good person..." he looked down and his brown eye watered.

'You can't be nice, Sebastian...We are a demon, remember?'

Mabel's heart broke a little at her uncle's words. How could he say that?! He was super cool and nice!

"But...But I had so much fun with you today! And I really liked it hehe..." he gulped. "It's been a while since I went to look for adventures!"

"Grunkle Seb?" Mabel asked confused. "I don't understand..."

"Yeah...What-What do you mean?" Dipper asked confused.

Seb sighed and took his legs to his chest. "I lied to you, ok?...This town is full of monsters-"

'Like you?'

"And it is really weird and dangerous...I just...wanted to keep you safe from them, but, seeing you are like a magnet for the weird!" He emphatized that and booped his nephews' noses. "I-I think I can show you around! But ONLY if I am with you! I don't want you getting into trouble and getting yourselves killed here! This town is weird as f-"

"No bad words!" Mabel covered her ears.

"Alright, fine!" Seb groaned playfully. "Sorry, shooting star. I'll try not to curse...too much" he laughed.

Dipper stared at his uncle gaping. So...He knew about the mysteries of the town?!

He glanced at his pillow and back at the man wearing the triangle shaped eye-patch.

"This journal told me there was no one in Gravity Falls I could trust..." He had written...

He sighed.

"But when you battle a hundred gnomes side-by-side with someone, you realize that they've probably always got your back..."

"Uncle Seb...I have to show you something..." Dipper lifted his pillow and grabbed the red old journal.

Sebastian's eye widened incredibly huge. Mabel thought it would come out of its socket!

"I found this weird book in the forest...It speaks about all the mysteries and creatures in Gravity Falls! We-We can use it as a guide to explore all the things the author found!" The boy exclaimed excitedly. "You said there was nothing wrong with this town but now that you admitted that you know! Imagine all the secrets waiting to be unlocked!"

Seb ran his five fingered hand over the cover, his eye watering at the sight of the golden hand with six fingers.

He opened the journal and examined the discoveries the author wrote down. It was there...everything was here... he quickly passed the page of Bill Cipher and stared at the page he needed...

'Pinetree has the journal...' Bill2 said.

Dipper has the journal...

Dipper carefully took his journal away from his hands and stared at him carefully. Had it been a good idea to trust him?

Mabel watched her uncle's expressions really confused. She was good at reading people but now she couldn't tell what he was thinking... Sebastian was shocked, that was for sure, but his eye was full of tears...Was he scared? Was he just so surprised to know someone else knew Gravity Falls was weird ? But he couldn't possible want it...could he? Why would he want this journal anyway?

"What...crazy lunatic went around the forest to write about this town?...haha...ha..." Seb said awkwardly.

"I don't know! The page where the name had been was teared" Dipper informed him.

Dipper has the journal. Dipper has the journal Dipper had the-

"Well, I think we can use this person's research to-to have a fun time exploring the forest...I guess..."

Dipper has the journal. Dipper HAS THE JOURNAL DIPPER HAS THE JOURNAL!

"But now!" He stood up clapping his hands. "Now you two go to sleep! It is late and we have work to do around here,kiddos" he smiled and ruffled their hair.

"Good night, Grunkle Seb!" Both kids said and the man forced a smile.

He closed the door and heard Dipper asking Mabel to turn off the lights. Mabel did so but apparently with her grappling hook because she knocked the light out the window.

He walked to the gift shop and the laughter faded away.

Sebastian quickly but as quiet as possible put the code into the vending machine, 1ABC, like he had been doing for more than a decade and it opened. He walked inside, looked around before closing it.

He used the elevator to go down to the basement where the damaged and dark portal waited to be awakened.

Sebastian snatched his eyepatch and threw it to the table, allowing his yellow eye to glow in the darkness. He pulled out Journal 1.

That was when his tears finally fell...

"Dipper has one journal..." he laughed as he cried.

It wasn't going to take 3 decades after all!


Well! There it is! That was the first chapter! (In this AU, Mabel and Dipper are Seb's nephews, not grand-nephews, btw :3)

Tell me what you think. Should I continue with both stories or do you prefer if I finish his life first before continuing this one?
