I don't own GF.

Returning from town Dipper was greeted by Mabel dressed in bright pink dress, and angry scowl. "Where were you?" she asked. "I thought you'll be home." she pouted.

"I just went out to eat." Dipper shrugged. "What is this whole fuss about?" he asked.

"Pacificas birthday party. I told you earlier that she invited us both." Mabel explained.

"I forgot." her twin lied. "And I'm really busy, but… you can bring her present from me." he decided remembering that he has few copies of his latest book, published just two days ago. After quick signing he ran down and passed it to Mabel.

"Are you sure you don't want to go?" Mabel asked once again packing it with box of chocolates she bought earlier.

"You know we don't get along. Besides I have to finish draft of my next book." Dipper shrugged.

"I guess you're right. Don't go to sleep too early, I might need you to pick me up." Mabel agreed and left. Pacifica send a limo for her. Going to his room Dipper shook his head at it. Well, what else could he expect…

After that Dipper got so invested in his work he noticed time when his obnoxious ringtone sounded loudly making him jump and curse. Looking shortly at clock Dipper cursed once more and picked up his phone. Screen was showing picture Mabel send him few weeks ago.

"Yes?" He yawned.

"Were you sleeping?" Mabel asked. Loud sounds of party could be heard, including far too familiar voice chanting 'pine tree'.

"No, I just noticed how late it is." he said ignoring it. "Need me to pick you up?"

"Me and Bill. He's drunk and Pacifica send her driver away. He live far from here." Mabel explained. "He'll be staying over… he..."

"Fine, but it all goes on you if Ford sees him." Dipper agreed and started looking for his keys.

Club wasn't all that far away, but far enough to make drunk walk home a bad idea. Entering Dipper was instantly greeted by hug from Bill who was, mumbling something about his book. Demon was completely drunk, but Dipper was guessing that it was his plan. Once he can talk with him one on one Bill instantly sober up.

"Get off." he groaned pushing demon off. Annoying as he remembered.

"I love how all your… books… have pines…. I luv pine… trees." Bill mumbled not moving an inch. "And… where is…hic… your hat?" he asked and giggled like teenage girl.

Mabel, Pacifica and other girls were no help to Dipper, who was trying to get Bill to sit in car for long enough to buckle him up and get Mabel in. They were just whistling and awing.

Finally, successfully seating the two, Dipper could drive trough empty town back to shack, thinking where will they room Bill. He preferred to not think about most logical solution.

When they arrived Bill was already starting to doze off mumbling. Mabel just said 'good night' and quickly left letting Dipper know that he had to share his bed with Bill. Along dragging half asleep demon up the stairs, all the way to attic bedroom. "If you plan to instantly sober up once in MY bed, you could do it now and walk on your own." All complains were ignored, and not wanting to wake Stans Dipper gave up and just dragged Bill upstairs.

With demon taking half of the 'bed' Dipper sighed and turned 'round to get himself some coffee but was stopped by long thin fingers grabbing his arm. "No all nighters for you, Pine Tree. We've got to talk." Bill said. Completely sober but a little tired. "It's serious on 'end of the universe' level." looking at him Dipper got feeling that it was indeed serious.

"Speak then." Dipper sighed turning to his desk.

"Mindscape. It's not safe to talk about it here." Bill said dragging him to the 'bed'.

"Fine, fine. I can go to sleep on my own." Dipper rolled his eyes lying down.

In just a second both of them were asleep in just a couple of minutes.

In mindscape Bill was already waiting for Dipper with tea. Seeing it teen in question rose one brow. "So?" he asked taking a seat. Bill was fidgeting.

"I'm not going to lie. We're in a deep shit, Pine Tree." Bill started. "Do you remember that six years ago I needed that rift to travel freely between dimensions? Well, in normal circumstances I don't require it." he continued. "Some years ago, long before Sixter got interested in supernatural certain someones kind off bound me to Mindscape away from ME."

Hearing way Bill said ME, Dipper understood that he got his model of universe wrong. Bill wasn't between dimensions. "You mean you're..."

"Call it how you want. Point stands that using you those someones can seal me again, along with certain parts of my memories and knowledge, Like ones regarding them." Bill said.

"What does it have to do with me?" Dipper asked. How was he involved in something that happened so long before his birth?

"Isn't Shermy Pines your grandfather? He is one of two someones and you and your sister are here just so he can seal me. Since shooting star was stronger they used her for second seal after one connected to some uncle of yours broke with his death. You're their safety measure, a back up plan. But if they do it shooting star will die." Bill was speaking faster and faster at this point to avoid any interruptions. "I'd guess they don't know about weirdmageddon." Bill stayed silent for a while.

"Yet..." Dipper said shocked. For someone reason he believed Bill, to some degree. "Grandpa is visiting in few weeks." he added. "And why should I even believe you?"

"Stopping me then you removed the seal. If I wanted world domination I would just rip the rift open and do it." Bill simply said calmly drinking his tea. "If Shermy is coming SHE has to be on her way as well." he noted. "I'm certain forest is feeling it already. Not to mention people having nightmares more often even without my intervention."

"Without your intervention?" Dipper asked confused. How?

"To begin with, I'm on a completely different level compared to most demons." Bill started. "Every small dream demon has his own task or specialisation. Call it how ever you want. Demon in charge of nightmares is gone so I'm taking her work." he finished as if he was talking about work in convenience store.

Dipper didn't know what to make of it. At least he had time. Three weeks of time, which in Gravity Falls wasn't always much. "I'll think about..."

"And I happen to have a free room in my house. And normal meatbaggy job at restaurant, where I have to be tomorrow, so if you'd excuse me, I'll just sleep. You can call me once you make up your mind, kid." Bill rambled and vanished not letting him finish.
