IT: Welcome to Derry Showrunner Explains Pennywise’s New ‘Birth’ Scene & Its Impact On Chapter 2’s Ending

The first season of IT: Welcome to Derry ended with Pennywise revealing he experiences all of time at once – his past, present, and future, even back to his very beginning. This means he’s aware he will eventually be defeated by Richie Tozier and the Losers’ Club in IT: Chapter Two, and it confirms Stephen King’s idea that this evil entity exists eternally, both before and after its death.
