"Gideon Rises"

After Gideon swindles the Mystery Shack away from Stan, everything in Gravity Falls appears to be even more west of weird – Dipper, Mabel and Grunkle Stan are forced to move in with Soos and his grandmother, while the town remains enamored with Gideon's charm. Meanwhile, Grunkle Stan isn't certain he can take care of the twins, and is considering sending them back home. Thus, the kids decide to take on Gideon and win back their home.
