HBO’s Stephen King adaptation delivered plenty of Pennywise, but we have some lingering thoughts about what happened and what’s next.

"We can only say the stuff that's already known, like it's in 1935, 27 years before season 1 and it involves the massacre of the Bradley Gang from the books," Muschietti told Variety. "It takes place during the Depression in Derry, and there are some new characters and some characters from this season as well, but younger versions of them."

Welcome to Derry finale may not reference The Mist on purpose — but its final Easter egg changes IT lore forever.

The Stephen King adaptation wrapped up its first season Sunday night on HBO with a little slice of fan service.

The video clip is taken from the final episode, "Winter Fire," from the first season of HBO Max's prequel show, IT: Welcome to Derry. This last episode shows the concluding battle between Pennywise and the youth from Derry.

IT: Welcome to Derry's finale episode reveals just how and why Seasons 2 and 3 will be set in new time periods.

Welcome to Derry" shows Charlotte Hanlon, portrayed by actor Taylour Paige, confronting a group of boys in town.

Elsewhere in the interview, Kane explained that the fog in “It: Welcome to Derry” is a direct call back to the final scene in King’s “It” novel, in which a flash flood occurs when the Loser’s Club duke it out with Pennywise for one final time.
