Upstairs dipper and mabel were playing cards. "Hey dipper hold on im going to get my shooting star sweater." Mabel said. When she came back they continued playing. "HEY GRUNKLE STAN NEVER GAVE ME BACK MY BOOK!" Dipper said "I am sure he will give it back." And Mabel patted his back. And thats when they were in a flash back. And not only was Mabel and Dipper in the flash back BILL CIPHER WAS THERE TOO! "GET OUT OF HERE I MEAN WHAT ARE YOU DOING HERE YOU MONSTER!" Dipper shouted. "I am here to show you you and your great uncle's past." Bill said with a soothing voice. The flashback started at Mabel And Dipper's house. There was a picture frame with 2 tiny newborns in it next to there mom. Dad and grunckle Stan. But there was someone or somthing in the backround It was Bill. Then in the mirror when dipper was singing like a girl there in the backround was bill making a dirty look. But no person sees him. Because out of gravity falls not anyone can see him. Then it switched to the mystery shack. There were two men there playing bingo. They bolth had brown hair. One man had so brown hair it was almost black. The other man's hair was kind of light brown. The two guys names were Stanferd and Stanley.The twins had surprised faces. "Keep watching." Bill said. Then teen Stan wandered off were the vending machine was. He did not have any cash. He looked sad. He put his arm on the buttons. Then the machine started TALKING! It said "Pick a password." He typed on 4 numbers. "Stanley get over here!" Stan yelled. Stanley ran over. Inside the vending machine there was labs and cameras and then there was a elevator. They hopped in. "How about 3!" Stanley yelled. He pressed 3. There was a lot of weird things. But when the wall ended there was a kind of shelf. Stan reached inside and pulled out a book with a 6 fingered hand on the front with a number 1. Then they appeared in stans mind. were bill's line was "Shooting star. Pine tree. Question mark. I had a hunch i'd meet you?" Then it flashed a picture of the Bill Cipher wheel and 2 symbols flashed. The PINE TREE AND THE SHOOTING STAR! Then the flashback ended.
