After arriving in Gravity Falls by literally falling into it, Matt is dazed and confused. He is sent back from 2020 to 2012 with his knowledge of the show and he soon finds himself in the Mystery Shack where Stanley Pines takes him in. How'd he get there? Why are things changing? I guess you'll have to find out along with him. (Self Insert that is not a copy and paste of the original plot!!)
