In Star Scattered au, what will happen with the Pines Parents? DaMvtF takes place only a week before Dip and Mab have to go home. Would rescuing Ford only take a few days, or would they have to come up with a way to stay in GF longer in order to rescue him?
Oooh, good question!
Ultimately, I don’t think Dipper and Mabel’s mom will never notice anything was awry. The kids will return home on the bus exactly when they were supposed to. Rescuing Ford, and then trying to come to a solution on how to dispose of/mend the rift would definitely take waaaay longer than a week, (and would send them searching through planets in the far reaches of the Milky Way in the process), but they do have the help of Blendin. So once everything settled… Once they rescued Ford and neutralized Bill’s threat… they’d just return to the proper time and spend their last few days in Gravity Falls without worry.
