Mabel carefully stuck a toe into the bathtub. She sighed with pleasure, noting it was the perfect temperature. She shut off the water, and lowered herself in. She submerged herself to her chin, and let the warmth overtake her. There was nothing more relaxing than a warm bath, and she needed some relaxing. She hadn't wanted to burden Dipper (who was clearly going through some stuff), but she was starting to get a little worried. Last night she had strange, unwelcome dreams. Mabel didn't normally have nightmares, so when they did come they were especially disturbing. She couldn't remember the details, only that someone had been watching her. It hadn't helped that, for some weird reason, she didn't like the carpet in her room. It seemed idiotic, but she was careful not to walk on it barefoot. She wasn't scared of it, it just made her uncomfortable. Seeing Waddles had helped her though. She couldn't believe she had forgotten about her pet. She remembered getting him from the fair, thinking he was so cute and cuddly. If she was staying with anyone other than Grunkle Stan, she might have had to send Waddles back. But Stan hadn't cared. She had spent the whole summer with the pig, practically attached at the hip. Soos was an awesome guy, taking care of him like that. She made a mental note to get him a thank you gift. Maybe she would knit him a sweater. And she was also thankful to Robbie. Jesus, Robbie. Mabel knew she had a tendency to fall head over heels way too fast (she had a line of irritating ex-boyfriends as proof), but there was something about Robbie that revved her engine. It wasn't even his looks (although he was a stud.) He had developed some sort of aura. It was almost supernatural. He exuded confidence. A feeling that if he wanted you, he could have you.

Mabel closed her eyes. She didn't normally like sleeping in the tub, but her restlessness last night was making her groggy. She started to sink into dreamland, the warmth of the tub fading. Things began to get hazy. There was a loud noise, and Mabel opened her eyes. She was still in the tub, but it was in another room. The walls seemed way to high, stretching into infinity. They were slate grey, splattered with red. She looked around. The massive room was almost empty besides her. The only other thing was a chair. A robed figure sat in it, facing away from Mabel.

"Hello?" said Mabel.

"Ah, you're here," the figure said. "Welcome. I suppose it's time we met."

"I recognize your voice," said Mabel. "I used to know you."

"No!" the thing shouted. Mabel jumped. The voice had so much anger in it. The figure was silent for a second, then it continued.

"No, no. You knew me before I ascended," the figure said. Its voice was calm. "I am different now. No longer the person you once knew. Thanks to the two, I have become something greater. Much greater. I'm no longer a human. No longer one of you."

"What... what's the two?" asked Mabel. The figure chuckled.

"Oh, that's right. You've forgotten," said the figure. "It will come to you soon enough. Your memories will return." The figure chuckled again. Mabel realized she was shaking with terror. "I guarantee you will wish they hadn't."

"Gideon," Mabel whispered. "You're Gideon." This time the figure laughed. Mabel gasped. It wasn't at all human.

"No. The Gideon you knew is dead," the figure said.

"But your voice..." said Mabel.

"Enough!" shouted the figure. Mabel could barely control herself. She was more afraid then she had ever been in her life. "I come here with a warning. I shouldn't, but you are owed one. You are pure of heart, pure of intent. It may not seem it, but I am not completely evil. It would bring me no joy to corrupt you." The figure cracked its neck, and continued. "Leave town. Get in your brothers car, leave, and never come back."

"But... but this is me and Dipper's-"

"DO NOT SAY THAT NAME!" roared the figure. The entire room shook with the force of it. "Do. Not. Speak of him." Mabel thought her heart would stop. The once warm tub was now ice cold. The chill seemed to seep into her bones. "He stays. You may leave, but he must stay."

"I'm not leaving without my brother," said Mabel.

"Fine," said the figure. "I did not think you would heed my warning. But now I can do what must be done." The figure slowly started to turn. "It begins, Mabel Pines. Gravity Falls will be destroyed." The figure was almost facing her now. "I regret that you must be destroyed with it." She looked down, desperate to avoid the figure's gaze. When she did, her last facet of calm faded. She was no longer in water. She was bathing in blood. She screamed.

"Mabel!" someone shouted. Mabel snapped awake, looking around. She was back in the bathroom. "Mabel, are you okay?" She was too overwhelmed to say anything. The dream was still fresh in her head, vivid like a recent memory. "Mabel! Mabel, I'm coming in!" The door swung open.

"Grenda?" Mabel stared at her friend. The look of worry on her friends face brought her back to earth. "It's okay Grenda. I was just having a bad dream."

"Oh, okay," said Grenda. They stared at each other for a second. "So, I'm gonna leave now," Grenda said. Mabel looked down, and covered herself.

"Yeah, I'm kinda naked and stuff," Mabel said. "Let me get some clothes on, and we'll hang out. It's nice to see you."

"Nice to see you too," said Grenda. She gasped. "Not like that. I don't mean that I like seeing you naked, although you're pretty, but-"

"Grenda!" Mabel shouted.

"Right, sorry." Grenda left the bathroom, and closed the door. Mabel leaned back against the porcelain. She wasn't embarrassed (they were both girls, it was whatever), but she was still scared. That hadn't felt like a dream. It had felt real. She felt like she needed to talk to Dipper. Maybe he had been on the money about Gravity Falls. Maybe something terrible was happening here. But that was later. Mabel got out of the tub, dried off, and threw on some clothes. She walked out, and saw Grenda sitting near the gift shop.

"Hey girl!" she shouted. Grenda lit up, and the two ran at each other. The hugged, Grenda lifting Mabel off her feet. She put Mabel down. "It's been forever."

"I know," said Grenda. "When I heard you were coming up, I had to see you."

"Thanks!" said Mabel. "Where's Candy?" Grenda frowned, and explained that she was in Korea for school. "Oh man," said Mabel. "That's too bad."

"Yeah," said Grenda. "But at least I got you." Grenda punched Mabel's shoulder, and almost knocked her down.

"Wow," said Mabel. "You're crazy strong now."

"Yup," said Grenda. "Started doing bodybuilding. It's been a lot of fun." As the two talked about what they had been up to the past five years, they wandered outside. As they did, Soos came back into the house. He walked around, sweeping and tending to some of the exhibits. After a few seconds, he felt a pressure in his bladder.

"Oh crud," he said. He set down the broom, and sprinted to the bathroom. He opened the door, and felt numbness envelop him. He fell to the floor, unable to accept what he was seeing. The bathroom was covered in blood. It was like someone had bathed in it. He closed his eyes, shook his head, and reopened them. The bathroom was clean. He did a double take. "What the heck," he muttered. He got up, and inspected the bathroom. It had the normal bathroom dirt, but nothing out of the ordinary. He shrugged, and put the incident out of his head. He went, washed his hands, and closed the door behind him.
