‘Welcome to Derry’ Delivers Most Shocking Scene Yet

News Desk 

Los Angeles:  HBO’s IT: Welcome to Derry escalated its horror to shocking new heights in its fourth episode, “The Great Swirling Apparatus Of Our Planet’s Function,” delivering what may be the series’ most and unsettling moment to date.

The prequel, set decades before the events of Stephen King’s It, continues to explore how Pennywise — played once again by Bill Skarsgård, according to IMDb — manipulates the fears and insecurities of Derry’s residents long before his full reappearance.

Although Skarsgård has yet to appear in full Pennywise makeup, the demonic entity’s influence permeates every corner of the town through increasingly grotesque visions and psychological torment.

Episode 4 begins innocently enough in a Derry High School science class, where students watch a film about parasitic flatworms that invade snails and transform their eye stalks into brightly pulsating targets for predators. The lesson proves to be a chilling foreshadowing.

The storyline centers on Marge (Matilda Lawler), a student coerced into participating in a cruel prank orchestrated by school bully Patty (Maya McNair). Marge is instructed to lure her hesitant friend Lilly (Clara Stack) into believing a boy has a crush on her, setting her up for a humiliating public rejection.

The plan unravels in horrific fashion when Marge follows Lilly to the bathroom to confess the setup. Before she can speak, Marge is struck by a searing pain in her right eye — the start of a Pennywise-induced hallucination that mirrors the parasitic lesson from earlier. In Marge’s distorted vision, her eyes begin to swell, elongate and pulsate in multicolored stalks, dripping blood.

Panicked, half-blind and screaming, Marge staggers out of the bathroom and into the school’s wood shop, where she desperately attempts to destroy the imagined stalks. In a sequence that has already drawn alarmed reactions across social media, Marge drives a chisel into her own eye before lunging toward a band saw. Ignoring Lilly’s frantic attempts to stop her, she uses the saw to sever both eye stalks in her hallucination — though in reality, only her right eye is ruptured.

By the time other students arrive, Lilly is restraining Marge to keep her from inflicting further harm, setting up a misunderstanding likely to have consequences in future episodes.

The moment adds to the show’s growing reputation for visceral psychological horror and cements Pennywise’s unseen presence as a terrifying force shaping the past and future of Derry. For viewers, it marks yet another reminder that in Welcome to Derry, the mind is often Pennywise’s most dangerous playground.
