Episode 4 of IT: Welcome to Derry has made the Stephen King fan community explode with excitement by delivering the densest amount of lore since the season began and opening up a series of secrets surrounding the origin of IT. This isn’t just a frightening episode — it’s a deeply symbolic, foundational chapter for the entire Derry universe.

Below is a complete breakdown of why Episode 4 is considered the best, most valuable, and most intense episode of the series to date.

1. The episode reveals the origin of IT – a mystery millions of years old

Episode 4 brings viewers back to the legend of the Shokopiwah tribe, clarifying that:

• IT arrived on Earth millions of years ago.

• It was imprisoned inside a meteorite, and the same meteorite material is capable of repelling it.

• The Indigenous people relied on this ancient “prison material” to push back and control IT for generations.

This is the first time the series dives deeply into this prehistoric lore — something both book fans and movie fans have long awaited.

2. Hallorann’s Shining ability is showcased more impressively than ever before

Hallorann’s psychic power is not portrayed briefly — it is shown vividly and dynamically.

He “hacks” into the memories of Taniel, a young man of the Shokopiwah tribe, thereby:

• Discovering the tribe’s origin story of IT

• Witnessing how they once contained it

• Connecting the spiritual world, memory, and history in a series of chilling sequences

This is the strongest Shining depiction since The Shining and Doctor Sleep.

3. IT symbolizes chaos, fear, and the eternal presence of evil

The episode presents a philosophy that:

• IT cannot be completely destroyed

• Humans can only identify it – restrain it – and live in balance with it

The Shokopiwah tribe maintained this balance for thousands of years — until outside forces interfered.

4. The arrival of Europeans breaks the balance and makes IT stronger

The episode portrays clearly:

• European settlers invading the forbidden forest

• They are hunted and devoured by IT

• Their brutality and ambition feed IT, allowing it to escape beyond the Western Woods

=> A chilling message: foreign evil can amplify the evil already present in Derry.

5. The reason IT appears as a missionary when hunting the female chief

For the Shokopiwah people:

• White missionaries were their greatest fear

• Therefore IT chooses that form to manipulate their psychology

IT also has a primal form: a ferocious deer/reindeer, reminiscent of the Wendigo, and was called Gallo/Gallu by the tribe, meaning “devil” in Babylonian mythology.

6. IT draws power from human ambition and malice

Episode 4 emphasizes this direct link:

• In the past: colonizers → empowered IT

• In the 1960s: the U.S. military seeks a “super weapon” → prepares to tamper with the sacred containment

Human greed is the key that triggers Derry’s disaster.

7. The appearance of Maturin the turtle – the counterbalance to IT

The episode includes numerous turtle-related details, symbolizing Maturin — IT’s cosmic counterpart.

• Shokopiwah children used 13 sacred stones placed inside a turtle shell to create a psychic barrier imprisoning IT

• It’s likely the military will break this barrier

This is peak fan service for those familiar with the Kingverse.

8. The episode also teases iconic locations: Black Spot & Neibolt Street

Episode 4 cleverly hints at:

• Black Spot

• The Neibolt Street house

• The underground sewer network connecting all of Derry

These clues show that the series is heading closer and closer to key events from the original story.

9. Lily’s fate – brutal, but with a glimmer of hope

Lily suffers heavily in this episode, but based on the signs from Maturin:

• She is very likely being protected

• And her chances of surviving are high

A rare bright spot in an episode filled with tragedy.

CONCLUSION: EPISODE 4 IS THE MOST IMPORTANT MILESTONE OF THE SERIES SO FAR

Episode 4 of IT: Welcome to Derry is a flawless blend of:

• Mythology – history – horror – spirituality

• Indigenous legends

• The Shining

• A warning about human greed

• Major symbols in the Stephen King universe

It’s not only terrifying — it’s illuminating, unveiling the grand picture of IT, of Derry, and of the age-long war between good and evil.

A complete, profound episode that truly deserves the title “best of the season so far.”
