[ You're a good bro, Hiro. ] Yeah. My grunkles used the old bait-and-switch and we erased Stan's mind and Bill along with it - long story, he got better. [ Abbreviation of the century. ] Gravity Falls was trapped inside this...weirdness bubble. I guess it explains why all the crazy stuff happened right in that town. When we erased Bill, we erased the Weirdmageddon, too, and all the damage basically reversed itself. Everything went back to normal.

[ Maybe a little too tidily, but hey, Dipper wasn't complaining. ]
