The mystery surrounding Henry Park’s disappearance becomes increasingly disturbing in Yaga Season 1 Episode 4, as investigators uncover a connection between secret woodland gatherings, an unusual substance and an ancient supernatural legend. Titled “Dance With The Devil,” the latest episode delivers two major developments: Olena Yaha’s shocking final revelation and a mysterious video of Logan’s dead body uploaded to Henry’s social media account.

But the biggest question remains unanswered: Who is controlling Henry’s account, and is the person behind the disturbing video connected to the mysterious Baba Yaga?

The fourth episode takes viewers deeper into the psychological and supernatural world of the series, leaving several important clues for the upcoming chapters.

Pam’s interrogation reveals Henry and Logan’s complicated relationship

Episode 4 begins with detectives Charlie Rapp and Carson investigating the circumstances surrounding Logan’s death. Their attention turns towards Pam, whose relationship with both Logan and Henry could hold important clues.

During questioning, Pam reveals that she and Logan had a romantic relationship when they were younger. However, things became complicated after Henry entered their lives.

According to Pam, Logan gradually developed an unusual obsession with Henry. He wanted to become more like him, copying his personality and appearance. Their relationship was not simply friendship, as jealousy, attraction and manipulation became increasingly intertwined.

The interrogation also exposes an uncomfortable episode involving all three characters. Pam explains that Henry wanted Logan to participate in an intimate encounter with them, but his behaviour suggested that he was more interested in watching the situation unfold than participating emotionally.

This revelation raises questions about Henry's personality and his possible involvement in Logan's death.

Although Pam becomes an important suspect, she maintains that she was elsewhere when Logan died and provides Hunter Nielson as a potential alibi.

What is Villy, and how is it connected to Baba Yaga?

One of the episode's most important discoveries comes when Rapp and Carson investigate a mysterious symbol found during their investigation.

Angel identifies the symbol as a triskele, an ancient three-part design associated with life, death, rebirth and different stages of existence.

She also introduces the detectives to Villy, an unusual substance connected to gatherings held in the woods.

Described as an organic dissociative tonic, Villy reportedly contains ingredients including chicken blood and human bone. It is used during gatherings known as Sabbats, where participants engage in strange rituals and manifestation practices.

The gatherings are associated with an elderly Ukrainian woman known as Laney, whose real name is Olena Yaha.

Angel confirms that both Henry and Logan attended these gatherings.

This discovery changes the direction of the investigation. What initially appeared to be a case involving personal relationships, jealousy and murder now seems connected to a much larger mystery involving ancient folklore and secret rituals.

What did Rapp and Carson discover inside Olena Yaha’s house?

Following Angel's information, Rapp and Carson visit Olena's property. However, nobody answers the door.

After entering the house, they discover evidence of the mysterious gatherings. Someone suddenly escapes through the back of the property before the detectives can identify them.

Inside, they find pottery marked with the triskele symbol and an old journal written in Ukrainian.

The journal contains unusual recipes, including references to Villy, along with illustrations connected to Baba Yaga. One particularly interesting drawing depicts Henry wearing a flower crown while holding a chicken.

The discoveries suggest that Henry's involvement with Olena's gatherings may have been considerably deeper than the detectives initially suspected.

Their investigation eventually leads them to a hospital, where they learn that Olena was admitted after suffering a fall.

Is Olena Yaha dead after whispering Baba Yaga?

The hospital sequence delivers the episode's most disturbing moment.

When Rapp and Carson meet Olena, she appears confused and occasionally struggles to distinguish reality from memory. Nevertheless, she demonstrates an unusual understanding of the symbols and people connected to their investigation.

When Rapp presents Henry's photograph, Olena reacts strongly. She calls him a bad dog and makes cryptic references to Villy, his teeth and something happening to him in the woods.

She also repeatedly mentions that there must always be three, connecting her words to the triskele symbol discovered earlier.

However, the most significant revelation comes when Rapp asks about the devil Henry wanted to dance with.

Olena explains that Henry wanted to dance with the devil just as she had. When Rapp presses her for the devil's identity, she takes his hand, kisses his palm and whispers two words:

Baba Yaga.

Immediately afterwards, her heart monitor flatlines.

The scene strongly suggests that Olena has died. However, the series does not provide a separate medical confirmation, leaving a small degree of uncertainty around her final fate.

Her death, if confirmed, would remove one of the most important connections between the detectives and the secret gatherings.

Who uploaded Logan’s death video on Henry’s account?

The episode's second major twist happens while Rapp is questioning Olena.

Carson receives a disturbing video that has appeared on Henry's social media account.

The footage takes viewers through Logan's bedroom, following a trail of blood towards the window. The camera then reveals Logan's naked body lying outside.

But the most frightening detail comes at the end.

The person recording the footage turns the camera towards a mirror, switches on a lamp and reveals themselves wearing the same mysterious mask that has appeared in Rapp's visions.

The identity of the masked individual remains unknown.

The timing of the upload is particularly suspicious. The video appears while the detectives are visiting Olena, suggesting that whoever posted it may know about their movements and could be monitoring the investigation.

There are several possibilities. The person could be connected to the woodland gatherings, someone close to Henry and Logan, or an individual who understands the secrets surrounding Baba Yaga.

Another important question is why the person used Henry's account instead of publishing the footage through their own identity.

It could be an attempt to expose Henry, manipulate the investigation or communicate something directly to the detectives.

At this stage, none of these explanations has been confirmed.

What does Yaga Episode 4's ending actually mean?

The ending connects the episode's two biggest mysteries.

Olena's final words suggest that Henry was not simply involved in unusual gatherings. He may have actively pursued something connected to Baba Yaga and the supernatural world represented by the show's folklore.

Meanwhile, the masked video indicates that someone still has access to Henry's digital identity and possesses disturbing knowledge about Logan's death.

The recurring triskele symbol, Villy, the woodland rituals and the masked figure may all be parts of the same mystery.

However, viewers should not assume that Baba Yaga is necessarily a literal supernatural character. The series deliberately leaves room for psychological, symbolic and supernatural interpretations.

The bigger mystery is whether Henry became a victim of the rituals, participated in something dangerous or is still connected to the person controlling his account.

What to expect from Yaga Season 1 Episode 5?

Episode 4 leaves the investigation at a crucial turning point. Rapp and Carson now have evidence linking Henry and Logan to Olena's gatherings, but they still do not know who killed Logan or who uploaded the video.

The unidentified figure who escaped from Olena's property could also become an important lead.

With Olena's final revelation pointing towards Baba Yaga, the next episode is expected to explore the mythology and the secrets behind the woodland rituals further.

For now, one thing is clear: Henry Park's disappearance is no longer just a missing-person investigation. It has become a much darker mystery involving obsession, identity, death and the possibility of something far beyond ordinary human understanding.

Yaga Season 1 Episode 4 ends without revealing the masked person's identity, making the mystery surrounding Henry's account one of the biggest unanswered questions heading into the next episode.
