The story will be unraveled as we travel farther back in time, matching Pennywise’s 27-year feeding cycle. Season one covered 1962, 27 years before It: Chapter One. Season 2 will jump backward by another 27, and season 3 will be another 27-year jump.
“The pitch to Stephen King was we’re going to tell a story backwards, and it has to do with that hint,” Muschietti told Deadline, adding that future seasons will clarify whether Pennywise is travelling backwards in a linear way, or whether he’s omnipresent. More importantly, we’ll discover if any actions Pennywise takes affect the events of the It movies.
According to Muschietti, we also haven’t seen the last of the original Pennywise, Bob Gray, nor his daughter, Ingrid Kersh. There will be a lot more to discover about the pair in seasons 2 and 3.
“We are going to know more about the Bob Gray of things, and we are going to know more about Ingrid, because Ingrid was around in the 30s,” he explained. “I think it’s a pretty tragic character. She’s a very specific, very unique character, because she’s a victim, but she’s a perpetrator too. She’s tricked into thinking that her dad is still there somewhere in the shadows of that monster, and she wants to liberate him, but the only way to see him and try to liberate him is by creating all these baits [and] all this pain, because she knows that he will show up.”
