Personified Gravity Falls

As of now, Bill has been playing to be on Gideon's side, Mabel was safe in the shakes basement. However, he didn't plan on one thing, Oregon and America, as well as the Personification of Gravity Falls to find Mable and save her. Much less that the oldest Pines girl had the heart of his comatose reduced brother, watching over her. (Maybe pairings based off of 'A Break In the Dawn')
