A lot happened during that first summer in Gravity Falls. Dipper and Mabel moved in with Stanley and Stanford. Mabel overcame her differences with Pacifica. Wendy and the gang went to college, except for Thomson. Oh and Robbie randomly left without saying a word to anyone. It's now three years later. The Pines twins are now sixteen. Robbie finally returns. And Dipper is more than happy to hear this. But what if he returned with an eternal curse and a darito shaped demon sending him after an important book? (Dipper x Robbie and slight Mabel x Pacifica)
