Last night i dreamt that S2 Ep 12 of Gravity Falls premiered, and here was the storyline:
Stanley and Stanford are talking about what happened and how Stanford ended up pushing his brother into the portal by accident. There are a lot of flashbacks, and Stanley is obsessing over Dipper and Mabel. Bill Cipher makes a deal with Gideon and helps him breakout of prison. So Gideon goes to the Mystery Shack and tries to get Dipper to hand over the Journals and Mabel but Stan brings out one of his guns and Gideon retreats.
Then for some reason Bill makes a deal with Preston Northwest to restore their family's reputation. In order to do this, Bill has to inhabit Pacifica.
Unfortunately the dream stopped around about there ;-;
