Mabel was sitting in her bed, texting with Dipper. She let her guard down while she talked to Dipper. She realized that she judged him way too quickly. She found out he was actually really funny and smart.
Someone then knocked on the door. "Come in," Mabel called out. Pacifica then entered the room and sat on the bed.
"Hey Mabel," Pacifica said. "I came to inform you that we're watching a movie downstairs."
"What film?" Mabel asked.
"Sunset," Pacifica said. "It's about a hot werewolf and a vampire who fight over a hot chick."
"No thanks, I'm going to go to bed soon," Mabel said. That's when Mabel's phone vibrated. Pacifica then grew a playful smirk.
"I see," Pacifica said. "You're texting a boy."
"No I'm not," Mabel lied. She didn't want her friends to figure out Dipper was her brother yet. She knew there was a big possibility that if she told them, she would be back to being a loser again. She had worked too hard to get to where she is today to go back now. "I mean, I'm texting a boy, but not like that."
Pacifica then snatched the phone from Mabel's hands. "Give it back," Mabel demanded.
"You're texting that boy from the Mystery Shack?" Pacifica asked.
"Yes, but-" Mabel said, before Pacifica interrupted her.
"I didn't know you two were dating," Pacifica said. "Sorry if my comment back there made you uncomfortable. I'll back off. I don't want to ruin whatever you guys have going on."
"We're not dating," Mabel sighed. She noticed the door was closed. "He's my twin brother."
"Wait what?" Pacifica asked.
"Yeah," Mabel said. "I just found out today. When we were babies, he was stolen from the hospital."
"That must be a lot for you to take in," Pacifica said.
"Yeah," Mabel said. "Can you not tell the others yet? I don't want things to change just yet."
Pacifica made a motion to gesture zipping her lips. The two girls then share a pleasant smile. "Goodnight," Pacifica said.
"Goodnight," Pacifica said, leaving the room.
The next morning, Dipper and the rest of the boys in his cabin went for a nature hike. It was lead by the camp counselor, Alex. Dipper had noticed strange things while they were on their hike.
While Dipper was examing a bush that he thought he had seen a gnome in, the biggest boy in the cabin, Levi, pushed him into a hole that was about to feet deep. Dipper let out a scream as he ate dirt. "Alex there was a misplace," Levi said. "We seem to have gotten a little girl."
If looks could kill, Levi would be dead. Levi then walked off. Dipper then noticed he was sitting on something. He pulled it out from under him. It was a journal with a hand with six fingers and a three on it. "What is it?" Dipper murmured. He opened it and saw weird supernatural things, like zombies or living gnomes. As he looked threw the pages, he saw a message that stuck out to him.
In Gravity Falls, TRUST NO ONE!
For some reason, that made his stomach twist. He got up, tucking the journal into his shirt. He continued carefully, unknown to him being watched by a living triangle.
