Mabel and Dipper are put in the care of Stan due to an accident that killed their parents.
One day 5 year old Mabel runs into the forest. Stan leaving Dipper in the care of Soos follows her. When he catches up to her he sees a wormhole. In the wormhole he sees Ford fighting Bill. Just before the wormhole is closed by Bill, Mabel walks into the wormhole.
When Dipper turns 12 Stan tells him the truth. Dipper starts helping Stan with the portal. Dipper also finds Jornal 3 around this time.
Mabel and Ford come back when the twins are 14. Mabel struggles to adapt to life on earth and starts to miss her life pre portal incident. Bill uses this to manipulate Mabel into causing Weirdmageddon. Mabel then struggles with telling anyone that she wasn't fully manipulated by Bill. Bill obviously decides that this should be the first thing he tells Ford when they next meet.
Dipper is still really passionate about the supernatural and the jornals. Ford starts spending a lot of time with him. Mabel at first is ok as she recently got Waddles but as time goes on she starts feeling like she has been forgotten.
It is a mix between Drifting stars and Reunion falls.
Don't worry I haven't forgotten about Deal Distortion
Ford has a habit of leaving young Mabel alone. Mabel being Mabel will often go out and explore (there main base is in the nightmare realm) this leads to Bill having to return Mabel to Ford. Young Mabel sees both Ford and Bill as her family.
Dipper actually befriends Gideon and Pacifica by the time Mabel comes out of the portal
Mabel walked through the forest. This world would always be strange to the 14 year old. Everyone told her that this was home, were she belonged, even Ford. This place was to peaceful. She decided to head back to the Mystery Shack before her thoughts overwhelmed her with homesickness.
He laughed to himself. Ignorant Fordsy, Shooting star feels so out of place. He knows if he plants doubt within her mind she would release the rift. She is alone, out of place. All he needs to do is wait for the right moment. Poor Shooting star.
