Another plot twist that I came up with for the final episode of Gravity Falls, Weirdmageddon. Instead, Dipper is the one to do the suicidal mission to take down Bill by himself. As said demon traps his family (Ford, Stan, and Mabel) in the triangular prison. Bill captures Dipper and notices that the deal they made back then during the sock opera still exist. Dipper is still Bill's puppet and has access to his mind. The demon finds out that Dipper has been keeping alot of secrets after the sock opera incident. I do not own Gravity Falls sadly. Billdip, don't like don't read.
