Anything To Stay With You (Editing)

It's Dipper's and Mabel's third summer in Gravity Falls, but things don't go as smoothly as their second one. Weirdmaggedon has started all over again ; much worse than before. There are more hench-maniacs, more terror - more deaths. And when Dipper gets taken by Bill, everything changes drastically. Why does Dipper feel like he's growing fond of the demon? What happened to Mabel's optimistic world? Will Both siblings be able to fix their past in hopes of a better future? Or will it all crumble down in flames?
