My theory: In "The Society of the Blind Eye" there is the scene when Dipper scrolls in the journal to show OldmanMcGucket the page with the Blind Eye so that he may remember at it. In this seconds you have to press the stop button and then you're able to see a page with 3 People that  have a rope tied around the belly and one of them jumps into a kind of portal. Maybe you know it ;) So I think in the next episode Grunkle Stan's brother will goes back into the portal without a "Good Bye" and Dipper Stan Mabel and Soos will try following him.
