Honestly it looks like a lot is going to diverge at those coordinates, which may happen next episode as I believe next episode is October 2nd in the timeline, and the title, "Let's Rock!", would fit if what seems is going to happen will actually happen. The Twin Peaks Sheriff's Department, the FBI Group of Gordon, Albert, Diane, & Tammy, as well as Mr. C and the Cheese Queen, are all headed for those coordinates on October 2nd, 2:53 PM, as that's when something is supposed to happen at that location (what is going to happen is left ambiguous, but it's implied it's when the two worlds intercede with each other or something).
To be seen what happens once they all get there, but if it plays out how it's being built up to as, it'll probably be a pretty huge moment in the series.
