A new wave of spookiness struck the town of Derry. HBO released a brief new teaser prior to the release of IT: Welcome to Derry Episode 4, and viewers are already buzzing about it: they seem both excited and fearful to some extent. The clip is not about jump scares but rather about creating tension. It displays several dramatic images, a creepy sound, and a solid indication that, finally, more significant things will change in the forthcoming episode 4.To the audiences, who have been enjoying the gradual and ominous buildup of the show, this teaser seems like the point at which you can no longer consider the action to be covert and subtle anymore, but rather poking at the dark roots concealed beneath it all. IT: Welcome to Derry Episode 4 appears like it is going to be a giant revelation to anyone who is a fan of horror with a real story and payoff.What the teaser shows View this post on Instagram Instagram PostThis is an old basic trailer trick: the new IT: Welcome to Derry teaser displays enough to give you chills without revealing the entire story. You have brief glimpses of a dark forest, a primitive carving partly overgrown in the earth, of a child fishing in the middle of nowhere, and two words echoing throughout: “Duck. Cover.”The teaser is aimed at establishing the atmosphere: eerie music, some dramatic shots, and the impression that something ancient has been awakened. It does not expose the monster or any huge plot twists, which obviously indicates that the creators intend the actual fright to be experienced in Episode 4, not in a commercial. And honestly, that works.The fans on X and other social media platforms are already examining each frame in detail, in search of hints about rituals, strange items, or ancient legends. The teaser is not very long, and that is the reason to call it effective; it suggests a point of origin without stating what it is. It gives you a question and leaves the next episode to reply to it.IT: Welcome to Derry Episode 4 View this post on Instagram Instagram PostThe IT: Welcome to Derry Episode 4 is discussed as the one that finally reveals how the origin of the “It” came into being. Indigenous lore that was presented earlier in the season is used in the show to provide a cultural and mythological background to the origin of Pennywise.The episode purportedly revolves around a myth of the Galloo, a primordial evil that arrived on Earth in a falling star. The ancestors were able to capture it and make a dagger from a fragment of that star as a shield. However, as the generations passed, the defense became less efficient, and the settlers did not pay attention to the warnings. As a result, the power of the creature became increasingly stronger, and eventually it gave rise to what Pennywise is today.The series is a continuation of the original story by Stephen King, with Shokopiwah’s addition of a backstory and new visual mythology that were not present in the book. Thus, the viewers will have something that will be both familiar (a concept of an evil coming back every decade) and new (the tribal past, rituals, and more in-depth reasons why they are so dangerous).The fourth episode of IT: Welcome to Derry is more about the atmosphere: scenes of origin, flashbacks about the memories, and the gradual realization that the past isn’t a mere part of the history that Derry lived in, but it is the root of the repeated tragedies in the town. Fans who have been keeping up with all of the hints are referring to this episode as a huge payoff.How to watchHBO released IT: Welcome to Derry Episode 4 on November 16, 2025.
