Welcome to Derry Episode 4 tightens its grip on the viewers with a far darker tone, deeper revelations of characters, and a fresh sense of looming dread. With Pennywise’s presence growing stronger each week, Episode 4 marks a turning point for the series, as it blends psychological horror, small-town secrets, and meticulously placed clues that hint at what’s still crawling beneath Derry’s surface.
Packed to the gills with emotional intensity, chilling encounters, and a narrative pace that amplifies the terror of what’s to come. Today’s review breaks down every major moment, hidden clue, and possible foreshadowing, plus why the internet is abuzz with theories involving Jaden Smith.
The Episode’s Rising Tension: Derry Is Getting Darker
Welcome to Derry Episode 4 gets right down to brass tacks: Derry is unraveling. What began with scattered weirdness and unobtrusive disappearances now feels like an all-out atmospheric shift. The lighting, sound cues, and camera work all present a sense of “something watching” near enough to every scene, which mirrors the growing paranoia among the characters.
The townsfolk are acting diversely. Some parents seem overprotective. Others seem too calm, and that is no accident. Derry has a history of collective denial—a behavior the show seems to be replicating with unsettling accuracy.
Character Arcs: Vulnerability, Trauma, and Foreshadowing
Episode 4 focuses a great amount on the emotional states of the core group. By this point, each character has his or her individual version of fear: memories resurfacing, nightmares worsening, and the feeling that something is wrong, even when no threat is visible. These emotional threads are important, most likely, because Welcome to Derry plays into the core concept of fear as a weapon.
Pennywise doesn’t only attack physical beings; he manipulates psychologically. Episode 4 illustrates this strategy quite distinctly. One striking aspect is how the fear in each of their characters starts to align with the gradual return of Pennywise. It seems the show is mapping a slow psychological bridge from their personal struggles to the supernatural threat that’s hunting them.
Return of Pennywise: Fleeting Glimpses, Resounding Impact
While Pennywise does not visually dominate this entire episode, the short scenes he is in are extremely effective. His presence is disturbing not because of jump scares, but due to the eerie build-up that precedes him. It feels as if the makers are using Pennywise sparingly, with almost mythical power. And when he does appear, the moment is indelible.
Episode 4 is full of scenes where the presence of Pennywise can be felt without him even having to be there, stretching shadows too far, echoing laughter down empty corridors, characters suddenly acting out of fear.

Hidden Clues You Might Have Missed
Episode 4 is full of hidden details leading into future conflicts and deeper mysteries. Here are the most important clues to pay attention to:
1. The Red Balloon Placement
The red balloon only appears twice in this episode, and neither of those times is by accident. Both scenes involve characters dealing with unresolved trauma. It says, almost explicitly, that Pennywise is targeting people first who are emotionally vulnerable, which is what the original lore stated.
2. Background Voices and Whispers
Several scenes include faint whispers that don’t belong to any characters in the shot. These whispers match patterns from earlier episodes, suggesting they may originate from the sewers—or from Pennywise directly.
3. Missing Poster Patterns
The missing children posters contain sequences of repeating numbers and formatting inconsistencies that are odd. Whether it is intentional or an Easter egg, it could hint at an underlying timeline anomaly or repeating cycle.
4. The Town’s Reaction
Adults in Derry continue having signs of selective awareness. In one scene, a parent reacts to the fear of a child not with concern, but instead with dismissive calm. This might indicate that Pennywise’s influence affects adults differently, or that some adults already “remember” but choose to suppress it.
5. Foreshadowing Symbolism
Now, pay close attention to the colour changes throughout the episode. Pale blue or grey tinted scenes almost always precede an event involving Pennywise. Warmer tones are used during moments of brief safety. This language of colours is not only consistent but also probably intentional.
The Sewer Scene: a Time of Change for the Series
One of the real highlights of Episode 4 has to be the tense sewer sequence, which dramatically shifts the story. The atmosphere is unbearably suffocating with its dripping pipes, distant humming, and slow camera movements that clearly show a nightmare. This scene gives not only some disturbing imagery but also key information: strange markings on the wall look like symbols connected with Derry’s ancient mythology; they are older than the town itself, which means that Pennywise isn’t just a monstrous clown.
Fan Theories Explode: Why Jaden Smith’s Name Keeps Coming Up
Although Episode 4 does not include Jaden Smith, his name has continued to pop up during speculation by fans. Some believe that, given early rumors of casting and the show’s proclivity for surprise guest appearances, he might have a secret or cameo role in episodes further down the line. Everything from the plausible to the wildly imaginative theories are out there. Some think he might play some kind of character involved in the history of Derry, while others believe he will show up for some sort of flashback sequence. None of this has been proven yet, but it’s just adding to the overall hype in the name of his speculated involvement.
Best Moments of the Episode
Episode 4 had a few scenes that have already been declared iconic by fans worldwide. These include:
The Mirror Hallucination
A character sees their reflection smile back at them long before they actually do. It’s quick, disturbing, and beautifully shot.
The School Hallway Sequence
Lights blur on and off in a kind of rhythmic Morse code pattern. It’s intentional, symbolic-almost unsettling-and adds another dimension to the mystery at hand.
The Clown Sketch
One character is shown drawing a clown without realizing it; this accidental piece of art reveals that Pennywise is able to control the thoughts, not just the actions, of others.
The Final Scene
The last thirty seconds of Episode 4 take a darker turn and end with a cliffhanger of laughter through a storm-drain grate. It sets up Episode 5 and ensures that the events of Pennywise’s appearance are only going to increase.
Does Episode 4 hold up? Absolutely.
In many ways, Episode 4 is the strongest episode so far, abandoning the non-stop jump scares in favor of psychological tension. It leans deeper into the mythology, while slowly pulling the main characters into the horror. It allows just enough of Pennywise to make audiences terrified, without sacrificing an ounce of his mystique. With this episode, Showtime’s Welcome to Derry proves it’s more than a simple prequel; it’s building its own identity, blending emotional storytelling with immersive dread.
What to Expect in Episode 5
With the pace and clues shown in Episode 4, viewers will expect:
- More direct encounters with Pennywise
- Character backstories converging
- A revelation regarding the symbols present in the sewer
- Rising tension between adults and children
A possible change in the timeline or the impression of events If that trend holds, Welcome to Derry Episode 5 promises to deliver one of the biggest reveals of the season.

Final Thoughts
Welcome to Derry Episode 4 is a master class in atmospheric horror. The emotional weight, deeper lore, and chill of suspense-it all fits, and there are subtle hints throughout that reward attentive viewers. The return of Pennywise feels inevitable and unstoppable, and the show is clearly preparing for a much darker, more intense second half of the season. Whether here for the psychological thrills, the mythology, or the fan theories-yes, even the Jaden Smith ones-Episode 4 sets the bar high and keeps the series compelling.
