Trust No one (dipper x reader)

Chapter 1: Bus Ride

___(y/n)___ pinched her nose to keep the smell of cheese and ranch dressing out. The bus was old and rusted, bare and dim. Nobody else was on except for the driver, who stared at ___(y/n)___ ominously. It made her feel uncomfortable.
___(y/n)___ turned back to look at her parents one last time before the driver closed the doors shut.

You couldn't believe your so called parents threw you on a bus to the middle of no where. It was your last summer after all, well your last summer of fun that is. Once this summer was over, you would never see your parents again until school let out. College was waiting for you, and you weren't so excited to greet it.
You scanned the bus to find a good place to sit, somewhere far as possible from the driver. All the seats were torn and covered with filth. Except for the last one. Which only had two initials carved into the cushion.
DP MP.
You set your backpack down and make yourself comfortable. You stare at the initials for awhile, your finger dancing along the carvings. 'Who could they belong to?'

Four hours pass and everything still looked the same. Making you believe that the bus was going in circles. Its getting harder to keep your eyes open at this point, you close them and rest your head on the window, going into a deep sleep.

DP:
"Mabel!! Mabel where are you! The bus is coming!!"
Dipper sits alone, calling for his lost sister. He panics as the bus gets closer and his sister is no where in site.
"Stay here I said! But nooo someone HAD to go running off to get a bunny!"
Dipper took off his beanie and scratched the back of his head. This was normal for her but it always got them into a lot of trouble.
The bus arrived, it stopped in front of Dipper and opened its doors. A cloud of cheese air punched Dip in the face, twisting his features.
Dipper slowly grabbed his bag and made his way to the bus. Hoping to kill sometime.
"WAIT FOR MEEE!!" Mabel sprung out of the bushes covered in leaves and roots. It made him laugh.
They entered the bus. 'Wow hasn't changed a bit. Still has the old smell.' As Dipper thought to himself, he noticed a young girl. Asleep peacefully in the only chair he cared to sit in.
As he began to walk closer to her, Mabel grabbed his shoulder tightly.
" Dipper." Her voice low and hushed "we can sit some where else.. Its okay"
He nodded and followed his sister to a nearby seat.

Hours had passed, both Mabel and the stranger were asleep, but not Dipper. Who was wide awake. It had been almost Five years now since they last visited Gravity Falls. He missed the strange people and creatures that made their home in that little town.
He dug his hand into his pocket and pulled out a worn piece of paper.
The letters had faded yet they were still visible:
See you next Summer!
