Oddly, Waddles seemed to like Pacifica a lot, settling comfortably on her lap as Mabel, Dipper and Pacifica were driven by her chauffer back up to the mansion. As Mabel chatted away about her daring escape from Ford, Pacifica tried, and failed, to ignore the cuteness which was Waddles.

Despite the severity of the situation, she couldn't help but giggle as the pig shoved its fat face into the window, looking out into the forest around them.

Dipper idly wondered how things would be different if he had let Waddles go with Pacifica instead of his sister. There really wasn't any use thinking about that though. He wouldn't admit it to anyone else, but Dipper still had feelings for Wendy, even if he knew they wouldn't be reciprocated as more than friendship. However, because he knew that they wouldn't be reciprocated, he also knew that stopping Robbie in that moment would be pointless.

Dipper shook his head, clearing his thoughts. He couldn't let himself be distracted.

Reentering the manor, Dipper stopped the butler for a moment, obtaining the last piece of his plan.

"Would you be able to deliver two cans of Pitt Cola to the room where we will be working?"

Pacifica raised an eyebrow, but didn't countermand him, and so the butler trotted off towards the kitchens.

Dipper nodded, "Then everything is ready."

Before they could enter the room, however, Pacifica stepped in front of the door.

"Dipper," she said, her voice firm. "Whether I trust you or not, I have to know what you are going to do. No matter what else, the man behind this door is my father."

"My bro-bro already told us his plan," Mabel answered as Dipper considered Pacifica's statement. "He is a good guy who wouldn't hurt a fly!" Mabel snickered at the rhyme.

Looking at Pacifica, Dipper knew she had seen through him. And knowing his sister as he did, even a half truth at this point would reveal everything he had kept hidden. And really, he couldn't blame her. If it had been his sister behind that door he wouldn't have let anyone through, not even his Gruncle's, without knowing exactly what they planned.

"I am going to summon Bill Cipher."

Dipper winced slightly at the flash of hurt in his sisters eyes, she really had thought Dipper had told her everything. But the look was gone quickly as Mabel grabbed his arm.

"You mean the evil triangle dream demon who possessed your body?" Mabel's voice was more serious that it almost ever was, even Waddles was startled by it. "Bill Cipher as in the guy who attempted to invade our Gruncle's thoughts?"

Dipper nodded, "It is the only way."

Mabel started shaking her head. "No. Just no. Bill is bad news Dipper, his last deal hurt you enough."

"What are you talking about?" If anything Pacifica looked more determined to hold her place at the door, Mabel's unusual seriousness and concern clearly shocking her.

Dipper sighed, and began to explain what he knew about Bill Cipher. He only wished he knew more.

"Bill Cipher..." He shuddered slightly, his last encounter with the triangle less than pleasant. "I suppose you could call him a dream demon, as much as 'he' is a 'he.' But it isn't completely true."

Dipper looked Pacifica right in the eye as he told her about the twins experiences with Bill. while he had to keep this from them as long as possible, she really did deserve to know all he did before they went forward.

Or most of it anyway.

"Dipper," Pacifica sounded slightly shaken, uncomfortable with the idea of Dipper being possessed. But she pushed forward regardless, "How will summoning this... creature... help my father?"

"He wont." Dipper was blunt and to the point, "However, I can use Bill as a bridge into your father's mind. Once I am there... Well, I will have to see what is going on first." He didn't mention that he would have no clue how to go about freeing Preston Northwest from whatever was gripping him, but he was sure that the answer lay in the man's mind.

Pacifica hesitated than stepped aside, but Mabel's grip just tightened on his arm.

"Dipper..." She said softly, "Don't do this."

"I have to Mabel," Dipper smiled lightly at his twin, "Don't worry, my plan is perfect. Trust me."

Mabel nodded and let go of his arm, and Dipper stepped into the room with the wild Preston Northwest.

"First things first." Dipper withdrew his last bag of fairy dust and tossed it over Preston Northwest, silencing his rambling and putting the man to sleep. He almost would look peaceful if he wasn't in his underwear surrounded by a disaster of a room.

With chalk, Dipper drew out a circle, complete with the image of Bill in its center and began to chant. The hair on the back of Mabel's neck stood up as she heard her brother utter the same words Gideon had as he had sent Bill to invade Stan's mind. Her heart nearly stopped as his eyes glowed blue with an otherworldly light.

Pacifica was likewise terrified. She had hoped that Dipper could simply cast some spell and fix her father, but she knew better than most that live is never easy. But even though it was for her parents, Pacifica couldn't help but wonder what this was costing Dipper.

The room drained of color... and then...

"Well well well well well well. I must say I didn't expect you to summon me Pine Tree."

-notes-

I originally planned to make this longer. But I didn't, for reasons. The next chapter will likely be a longer one, simply because I am thinking that will be the best way to tell that part of the story. But it might not be, I'm not much of one to commit to this type of thing. I should mention that Dipper was lying last chapter about the fairy dust killing pain. It might, or it might not, I don't know. However, the only actual thing that we see fairy dust do is knock out the unicorn, and I prefer to keep as much of my work as canon as possible. A note on chronology as well, this fic is set between "The Stanchurian Canidate" and "The Last Mabelcorn." This will become important later, unless it doesn't. Oh and fair warning, the next chapter will likely start to earn that M. and not for sexy reasons.
