Welcome to Derry finale packed in several revelations that tie into the two IT movies, the last one released in 2019.

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.

Ingrid Kersh's appearance in Welcome to Derry isn't the first time we've seen her. Obviously we get much of her story in this series, including her working at Juniper Hill, and her childhood history with Bob Gray and as Periwinkle, his apprentice.

It: Welcome to Derry introduces Elfrida Marsh, linking the movie to the Andy Muschietti films. Read on to know more.

IT: Welcome to Derry co-creator, director, and executive producer Andy Muschietti has no plans to leave Stephen King's fictional Maine town anytime soon.

IT: Welcome to Derry Season 2 has not yet been renewed by HBO, but Pennywise's story suggests it will definitely happen.

Welcome to Derry has just ended, but creator Andy Muschietti is already teasing prospects for further seasons.

Elfrida Marsh is not a main character in IT: Welcome to Derry, but her presence in the post-cred scene is what drives the story forward 27 years later for the Losers Club. She is Beverly Marsh’s mother, and the show finally places her in the timeline in a way we understand.

Pennywise was always going to slither away for another 27-year slumber, but boy did he wave good-bye with gusto.

Next year, you’ll get a chance to experience the haunted town of Derry once again when Warner Bros. Discovery Home releases It: Welcome to Derry: The Complete First Season. Arriving on a 4K UHD in a Limited Edition Steelbook,
