A few things to know before you read

This is an AU where only Dipper, Mabel, Pacifica, Candy, and Grenda's genders are changed. Every other character remains the same gender they are from the show

In this AU Gideon had a crush on Dipper, and is more controlling than he normally is in the show

Dipper never had a crush on anyone while she was 12 in Gravity Falls

The events of the Last Mabelcorn took place, just again different genders

In this AU the twins never met the Northwests, so when they do meet them it would be their first encounter. So obviously the events of The Golf War and Northwest Manor Noir never occurred

This story takes place 5 years after the actual show, and the twins are 17 and graduated High School

All characters belong to Alex Hirsch and the Disney Corporation

Mark=Mabel, Patton=Pacifica, Cody =Candy, Greg=Grenda, Dipper keeps the same name

Outfits

Dipper wears blue skinny jeans, a black T-shirt, and and orange dress shirt, and instead of a blue and white truckers hat, Dipper wears a beanie with the same color scheme and pine tree

Mark wears elaborate sweater or sweater-vests, (Will be described as chapters go)

Patton wears regular blue jeans, plain white T-shirt, and a Purple Letterman jacket

Everyone else has the same sort of outfits, with Cody wearing brown jeans instead of a skirt

Chapter 1

Dipper and Mark Pines were both looking out the window of the bus as they passed the Welcome to Gravity Falls sign, "Wow, hard to think its been five years since we've been here, eh Dip?", asked Mark as he nudged his sister's shoulder.

"Yeah," sighed Dipper as they came closer to the Mystery Shack. She was ecstatic, their parents had finally let them come back after so many years as their "Graduation Trip". I wonder what has changed since we were gone thought Dipper as the bus slowly acme to a stop. The twins got up and grabbed their bags, as they stepped off the bus they were greeted by two old men, arms wrapped around eachothers shoulders, "Dipper! Mark!" they cried out together. "Grunkle Stans!", cried out Mark as he rushed to give them a hug.

"Hey Mark, great to-", started Stan before he was cutoff by a bear hug from Mark.
"Ford!" cried Dipper as she went to give a hug to her other Grunkle.

"Ha, its great to see you to Dipper", said Ford as he returned the hug. Meanwhile Mark had released Stan as he gasped for breath, "Well, I can see you've clearly been working out." Stan put his hands to his lower back and tried to straighten it.

"That what happens when you cheerlead," said Mark as he put his arms up and flexed.

"I didn't know you were a cheerleader Mark," said Ford.

"That would explain the shirt," said Grunkle Stan. Mark looked down at his blue and white sweater that had pompoms on the front of it.

"Yep, I was captain of the squad, we were awesome! Nobody could out cheer us!"

"But they could certainly out play our school's sport teams," said Dipper sarcastically. Her and Ford laughed to themselves.

"Did you do any sports Dipper?" asked Ford.

"I was apart of my schools quizatholon team, we won the state tournament" replied Dipper.

"Impressive," said Ford with a proud look on his face.

"Thats enough talk, c'mon lets head inside." said Stan as he started towards the Shack. Mark and Dipper picked their bags back up and followed. Once they entered the Shack, they were quickly greeted by Soos.

"Dudes! You made it!" cried out Soos. Mark ran and jumped on to Soos like a monkey, "Soos! Its so great to see you!" The two laughed and hugged as Wendy approached the group, "Dudes, nice to see you again."

"Same to you Wendy," said Dipper as she gave her a fist bump. Mark had finally jumped of of Soos and went to go give Wendy her hug, while Dipper gave Soos a high five.

"So what have you guys been up to?" asked Mark.

"Well dudes, you remember Melody?" said Soos.

"Yeah, why?" asked Dipper, though she already knew the answered. Soos's left hand had already given it away.

"Well dudes, were like getting married," answered Soos. Mark let out a scream that caused everyone to have to cover their ears. "SOOS! THATS INCREDIBLE! WHEN ARE YOU GETTING MARRIED?!"

"We're getting married in like two months, I was hoping that you dudes would come," said Soos.

"Of course we'll go Soos," said Dipper.

"Great! I'll give you more details later, but first hows about you two go unpack your bags."

"Good idea," said Dipper as she picked up her bags and made her way towards the stairs. Mark followed quickly behind. "Once you guys are done, I'll start up some dinner and we can catch up then," said Stan.

"Alright!" cried out the twins in unison. They went up to the attic and put their suitcases on their beds. Dipper went to the dresser and put all her jeans and shirts in their respected drawers, while Mark started to hang up his sweaters and other odd apparel along the raptures of the attic. "Man Dip, this is great! This summers is going to be the best!" said Mark as he started to try and organize his glitter and stickers by color.

"I know Mark, I can't wait to start working down in the lab with Ford and see what he and Stan have been up to since we've been gone." replied Dipper cheerfully. Even though she did enjoy High School, it was noting like the summer she had when she was twelve. She missed being in Gravity Falls and all its antics. She finished organizing the last of the books she brought for the summer and turned around to Mark. "Well, I'm all settled in, you?"
"Yep!", replied Mark with a grin. "Now lets go eat! I'm starving," said Mark as he rushed towards the stairs, Dipper laughed and quickly followed.

Well, thats the first chapter. I know it might be a little slow, the story will pick up, its just difficult to write introductory paragraphs. I'll try to post a chapter or two every week, but with college and sports there will be some weekends I miss. Hope you enjoy, and don't be afraid to leave a comment.
