He leaves Dipper Pines in Reverse falls and Dipper Gleeful into Gravity falls. They both must find a way home. In the meantime Gleeful gets to deal with the crazy and Goody Two Shoes Pines family, While Pines learns he is dating Pacifica and his sister is apparently sorta evil and insane. Great.

Definition of Semblance: The state of being somewhat like something but not truly or fully the same thing.
