It Chapter 2 isn't actually a sequel to It Chapter 1, but a continuation of the same story--which means it does more than just pick up where Chapter 1 left off, it goes back and weaves all sorts of new information into the events we saw transpire back in 1989. While this is great--and an opportunity to check in with those lovable kids who starred in Chapter 1 all while keeping an eye on their adult selves--it also means that the timeline of events can get a little bit confusing with all the retroactive continuity being laid out.
It Chapter 2 Coverage
But never fear--we're here to help. By cross-referencing the details of the two movies--everything from the occasional month and year title card to the various outfits the characters wear--we've put together a complete timeline of events between It Chapters 1 and 2 to spell out not only the journey the Losers took across all 27 years of their ordeal, but also the history of Pennywise in Derry according to this version of the story, in chronological order.
