This is just a fandiction an online friend and myself came up with for the ending of gravity falls that we both hope happens. It is not detailed, but more of a simple outline from notes and points in a short story format. Please enjoy and feel free to tell us how you thing it will all end!
That was it. Bill was defeated and gravity falls was left in a mess. Nothing that couldn't be fixed within time though. Everybody, Stanlee, Stanford, Dipper, Mable, Wendy, and Soos all decided it was time for bed. All the camotion and saving Gravity Falls made them tierd and hungry.
Dipper and Mable the next day played like it was any other with their water balloons and popsicles. Laughing, running adound, and enjoying their last day of summer vacation. Not long after Grunkle Stan came out to where they were playing and handed them their bags, "Your bus is here kids. Say goodbye." The old man said in his scruffy voice. Dipper and Mabel hughed everyone and they even cried, even though Dipper tried to hide it while Mable didn't, and gave extra long hugs to Stanlee and Stanford. After saying their goodbyes they got onto the bus that would take them away from Gravity Falls and back home. The bus ride was long and bumpy and Mabel hummed or slept most of the way, but adventually they got back home where their parents met them to pick them up. From that moment to after supper and it was time for bed once again, the children wouldn't stop talking about their adventures how Grunkle Stan was fraud, the portal, the jurnals, waddles, summer crushes, and new discoveries! They even told them all about Bill and the caos he created and how they saved Gravity Falls in the end. Thwir parents assumed it was another made up adventure they had and laughed it off. They put the kids to bed and tomorrow was school again. End of the summer. Mabel fell fast asleep, but Dipper was thinking of Gravity Falls still and how exiting it all was. Dipper dug into his backpack to recall the memories and his favourite parts, and he also found a bobble head of Grunkle Stan from the Mystery Shack. Dipper put that bobble head on his shelf and thought of how Grunkle Stan must have snuck that into his bag. Dipper whispered, "I'll see you guys next summer." And shortly after fell asleep.
