His willingness to confront danger culminates in brutal acts that reveal his capacity for violence when defending Jane.

A psychiatrist connected to Barbara's scheme, who initially reassures Jane but becomes entangled in the web of manipulation. He is murdered after being drawn into the case, illustrating the danger that surrounds those who get too close to the truth.

Leader of the cult, charismatic and dangerous, who presides over the Black Mass and guides Jane deeper into the group's rituals. He embodies the seductive appeal of power that masks a predatory agenda.

The blue-eyed man who acts as an instrument of the cult’s violence, targeting Jane and revealing a family-connected motive for the cult’s reach. He is ultimately slain by Richard, exposing a deeper layer of betrayal.
