It has been been 4 years since Ford used the memory eraser on his twin brother, Stan, to get rid of Bill Cipher, a triangular dream demon, once and for all. The young twin, power duo, Dipper and Mabel Pines, had went home from Gravity Falls, where their Gruncles Stan and Ford, lived.

"Mabel, I'm so excited to go see Gruncle Stan and Gruncle Ford again. Aren't you?"

Dipper and Mabel were driving from there home town of Piedmont California, to the town where they spent their summer as 12 year olds. The little known place, full of weird things, called Gravity Falls.

"Yup, and I cant wait to see Candy and Grenda either," replied Mabel.

As they pulled up to the Mystery Shack, they saw a lot of tourists. "Well, I guess we still have customers," Dipper chuckled, "and lots of them."

After Dipper parked their truck, they went inside, where they saw Wendy, at the cash register, and Soose, picking up fallen merchandise. "Dipper!" Wendy exclaimed when she saw the twins. She rushed over to Dipper and Mabel, and drew them into a tight hug. "Man am I glad you 2 are back. It's been non stop busy around here since, well, since Bill."

Soose heard Wendy talking to Dipper and Mabel, and also rushed over to greet the twins back. "Dudes, I have great news! Melody and I are married now."

"Oh my God, thats great!" the twins congratulated simultaneously.

Gruncle Ford walked into the gift shop, and he saw the two twins. He went over to them, and helped them carry their stuff up to their rooms. This time they had separate rooms, now that they were 16, and not 12. When he was in Dipper's room, he said to Dipper, "Stan is acting a little, weird. When I ask him if he wants to talk, he says he doesn't want to talk to anyone but you about it." He was talking quietly when he said that. But as soon as he was about to say something else, he heard Stan, in the hallway, "Welcome back to the shack Dipper. You know your way around here."

After he walked out, Stan walked in. "Dipper, we need to talk," he said nervously as he shut the door behind him. "Have you ever seen, this thing... in your dreams? It's a triangle, like, thing, with a, bow tie, and a black hat."

At this question, Dipper pulled out his pencil, and got a sketch book out of a bag of his. When he quickly drew the only thing it could be, Bill. "Like this, but yellow?"

"Yes! Exactly like that!" Stan almost yelled, if he hadn't caught himself getting loud. "EERT ENIP ELLOH!" Stan couldn't help himself from saying this.

Dipper handed his Gruncle a piece of paper and his pencil, and asked him to write what he said, realizing that it sounded familiar. When he read it forwards, it read, 'Hello pine tree'. There was only one person that ever called him Pine Tree, AND spoke backwards. "Bill," he muttered. He then grabbed a piece of paper with something that Stan didnt understand written on it. He grabbed nine candles, put them in a circle, lit them, and said to his Gruncle, "Do you trust me?""

"Something tells me I should trust no one," he started, "but yes, I do."

Dipper nodded, placed his hand on Stan's forehead, "Videntis omnium. Magister mentium. Magnesium ad hominem. Magnum opus. Habeus corpus. Inceptus Nolanus overratus. Magister mentium. Magister mentium. Magister mentium."

At this Stan fell to his knees, which Dipper had to follow with his hand. "SIHT OD TNAC UOY!" Stan's eyes glowed blue, as he arched his back.

When Stan's eyes went back to normal, Dipper exclaimed, "SEMIRC SIH ROF YAP NAC EH OS MORF NAMUH A ONTI LLIB NRUT LTOLAXA EHT EKOVNI I!"

At this Dipper's eyes glowed blue, and his hand was engulfed in a blue flame. He moved his hand around the circle of candles, until he felt something in mid air. Upon contact, this thing glowed blue, and showed bill, as his triangle self, turn into a human like figure. "Pine tree! What have you done?" Bill's voice was audible for anyone around, he was also visible. He was no longer the triangular dream demon that he was. He was now human, living, breathing, and susceptible to pain, tiredness, and anything else that humans are.
