Journal #3 is the canonical journal that the author had and that Dipper discovered—as best as we could create it. And many lingering Gravity Falls trivia questions, whether it’s about what happened to Ford when he went into the portal, or what Dipper’s real name is, will be addressed. It has interesting significance to the lore of Gravity Falls, but that didn’t directly affect or alter the characters’ choices or actual plots in the series. So it’s this really cool companion piece full of secrets and riddles. I will say this: Gravity Falls is a show about mystery, that itch you get when you’re curious. That itself is a really cool, inspiring thing. It’s a thing that drives forward curiosity, that drives momentum and adventure and exploration, and to answer every single question would be counter to the spirit of the series. Even though Journal #3 will have plenty of new answers and surprises, there are some things that we will never know. That’s just the way I like it.
