The fire was paranormal energy that attracted a poltergeist.
- According to Missouri, Azazel came into Mary's house, slashed her stomach, pinned her to the ceiling and then set the whole house on fire. The fire represents the paranormal energy in the house that attracted an invisible, telekinetic poltergeist.
The poltergeist was born out of Mary's wound.
- Since Azazel killed Mary and left behind an infected wound, it created a poltergeist, but the paranormal energy is what actually attracted a poltergeist.
Mary's wound gets infected with paranormal energy.
- While Mary's wound Azazel left was infected with paranormal energy, it created poltergeist and won't rest until all of the others who came into the house after Mary's death are dead.
Azazel is the one who created the paranormal energy in the house.
- When Azazel arrived at Mary's house, he left a wound behind on her. As it gets infected, Azazel created a bunch of paranormal energy in the house.
