The forest (Prologue)

Welcome to the Future! It's four years later in Gravity Falls, Oregon and the weirdness is there as always. Dipper and Mabel, now 16, are back. Soos and Melody are married and have a kid named Stan. Pacifica is nicer now. Gideon is still trying to be a normal kid. Stan and Ford are adventuring. Everything seems, well, normal for a change. But in the woods, a statue lies. No longer an equilateral triangle, the Bill statue is now human. How? Why? Nobody knows. Will Bill remain a statue, or will they really "meet again" as promised? It's up to Dipper to find out.
