The Cipher's Curse

After Ford returns and settles in to live with the mystery shack gang, Dipper starts to hang out with Ford more than his own twin and drifts away from her. One day, Mabel decides that she's had enough and confronts her brother, trying to tell him how she was feeling. All of that only resulted in the two fighting and splitting up. In a rage, she steals Dipper's journal and runs off into the woods, where she runs into Bill Cipher. There, he bribes Mabel into making a deal with him and vanishes soon after. She thought the small deal was nothing, but what she didn't know was that it would lead to death, destruction, and complete disaster.
