chapter 1

It was an ordinary day for Dipper Pines until he got the letter, it was an application for a summer internship for one of the world's greatest scientific research centers.

"Finally this is it." he thought a huge smile on his face "This is my chance to make a name for myself,a chance to unravel the greatest mysteries of the world, a chance to…" he cut off as he looked at a picture on his desk. It was a photo of him and his twin sister Mabel, his smile faltered as he looked at the photo and sighed he hadn't seen his sister in years.

Dramatic flashback

"And then Dipper jumped off the cliff and smashed through Mecha Gideon's eye and saved me!" Mabel shouted in the back seat of the car telling the the story for about the fifth hundred time in the six months since they'd been back in Piedmont.

"Thats nice dear." Their mom said not really paying attention as moved down the icy stretch of highway.

"I hope you're both as excited to see Grandpa Shermy as you were to see Great Uncle Stanford erm... Stanley"

their Dad said cheerfully.

"You both know we're not" Dipper said flatly

"aw come on he's not that bad...hey what is that?" Suddenly They're Dad hit the brakes swerving to miss a snow bank and flew off the side of the road skidding to the edge of the cliff. Dipper groaned rubbing his head and the lumber jack hat he was wearing, Mabel lying unconscious next to him gave a little whimper.

"Mabel!" Dipper shouted grabbing her and pulling her out the broken window. He laid her in the snow 15 feet away and ran toward the the wrecked car witch to his horror he saw was slowly starting to slide over the edge

"Mom!, Dad!" he screamed

"Dipp...(cough) (cough)...er he heard his Dad say.

"OhmygodhangonI'llcallforhelp!"

"Dipper the car is going over the side, are seat belt release is busted we can't get out."

"No no no no no no no no no no!"

"Dipper we need you to be strong, we need you to be strong for Mabel, we need you to keep her safe, can you promise to do that?"

"Yes, yes I promise!" For the first time his mom spoke, she smiled and said

"we love you." and that was all she needed to say. "Now go and keep your sister safe." Dipper looked at his parents one last time and crawled back to sister, he held her head in his lap as the car started to speed up, he held his sisters head in his lap as the car finally went over the side, and when Mabel finally regained a portion of conciseness he cradled her head and told her everything was going to be alright as sirens wailed in the distance and the sound of the car smashing at the bottom of the cliff echoed through the silent valley.

End Of Dramatic Flashback.

Dipper sighed as he placed the photo on his desk and looked at the lumberjack hat on the back of his chair

"well time to pack for that summer internship" he thought as he placed all the supplies in a backpack and glanced at the calendar to see how time he had to get there, his stomach flipped his seventeenth birthday was tomorrow! "Wait I thought my birthday was on the last day of summer not the first" he looked puzzled then shrugged "meh" he said then looked at the route he had to take to get there and his mouth fell open

"no way" his route went directly through a sleepy little town called Gravity Falls Oregon.

"Maybe it's time I saw some old faces" he said with a small smile on his face as he looked at a map of gravity falls. At the town of gravity falls at that moment Mabel Pine pulled up in front of the Mystery Hack, sorry Shack and smiled a braces free smile.

"Hey Mabel how's it hanging?" said Wendy passing by,

"Hi Wendy!" she said with a huge grin on her face. Her grin faded as her gaze lifted from Wendy's face to her hat, it was her brother's old hat it made her miss him even more. She sighed, Wendy who was like an older sister by now, knew exactly how she felt.

"You really miss him don't you?" Wendy said giving her a sad look,

"Yeah." Mabel said mournfully "I mean we used never go anywhere without each other, and now I haven't seen him in years I just wish…"

"WENDY why aren't you working!" a loud cranky old voice shouted.

"Oh crap!, its Stan!" Grunkle Stan was eighty something but still had it, which he proved while walking over to them. At the end of that fateful summer Stan had left the Mystery Shack in the capable hands of Soos and his girlfriend (now fiance) Melody. Whose wondrous new attractions in the first week alone caused three vandalism cases, five lawsuits, two attempted suicides, one successful suicide, and ten people losing all traces of sanity and trying to kill everything in sight. After that Soos decided to stick with the classics like the good old "Sascrotch." Grunkle Stan and Great Uncle Ford had an amazing trip around the world until they learned about what happened to Dipper and Mabel's parents. There had been an intense legal battle about the twin's future, in the end Stan and Ford had gained custody of Mabel but Dipper… she didn't want to think about it. When they arrived back at Gravity Falls Stan reclaimed his role as "Mr. Mystery" and Soos went back to being the handyman, but now he had a lovely assistant, which he was fine with.

"Wendy!, you're supposed to be restocking the gift shop!" Stan screamed interrupting Mabel's thoughts.

"Uhh, come on man that takes forever I'll never be done by sundown!" Wendy groaned.

"I'll help" Mabel said eager for a distraction,she and Wendy walked in into the shack and began the long process of restocking the shelves. Soos taking pity on them came to help,fixing a broken pipe behind the counter. They were about a third of the way done when they heard the bell tinkle indicating that someone had entered the shop, Wendy looked up and Mabel heard a sharp intake of breath as she froze. Soos oblivious to Wendy's reaction turned to greet the newcomer

"Welcome to a world of- HOLY TOLITO!" he shouted upon seeing who it was. Mabel shot straight up and whipped around expecting to see some horrifying monster they would have to fight! Instead she saw the last person she thought she would see, it was… it was… it was … him. He looked the same, but different, he still wore an orange t-shirt and that apart from his face (which had only changed a little) was the only thing that looked anything like her memories. He now wore a light grey hoodie that he left unzipped with the hood back,a pair of blue jeans, and some black sneakers. He wasn't wearing a hat anymore, but bangs still covered his forehead and then he spoke

"Man this place hasn't changed a bit." It was the same voice though a bit deeper and it didn't crack anymore. Slowly my eyes began to water as I stared at him "Di-Di-Dipper?" I said shakily, he smiled and set a backpack on the floor

"Hey sis"

"I'm back."
