What if in the ‘Not what he seems’ Gravity Falls episode, Mabel had to get sacrificed so that Stanley could come back home. And years later Dipper would try to bring Mabel back and they’re all aged up and Grunkle Stan, Stanley and Waddles are not there anymore because they all passed away. And either Gideon or Bill would take over Gravity Falls. What if that actually happened?! I’m such a horrible person. I’m going to hell for this.
