In season 5, Lydia spoke to the entity of the hellhound, who was "beyond life and death", but this entity has yet to reappear after it came to an understanding with Parrish. So what happened to this entity and why couldn't Parrish or Lydia talk to it to gain useful information about the Ghost Riders and Anuk-Ite, two supernatural creatures linked to the hellhound? Also, does the same thing apply to Halwyn? Is he also just a vessel, connected to the true entity of the hellhound?
