It is evident that something is going on between the two because, after an argument between Terrence and Joan, Gabriel Case tells the servant, "See she forgives him."

Terrence opens a door to find a family and two priests who throw holy water at him, burning him.

When Anna and Joan go for a walk, they notice they can no longer see any lights coming from the city even though it is just across from the island.

Terrance also has trouble remembering if he brought his dogs along with him, and the other members of the group get strangely confused when he asks them.

In the story's climax, a paranormal entity attacks Joan and Terrence while they're in a room together, banging on the door furiously as it tries to get inside.

It is revealed that Gabriel and the Servant were actually the doctor and his wife who had haunted the house before Joan, Terrence, and Anna showed up.

Anna Trawley – a psychic that gained her powers in a car accident that killed her daughter, she is very much aware of the haunting of Elsewhere.

Gabriel Case – although he passes himself off as a paranormal investigator for much of the book, he is actually the ghost of the doctor that murdered his wife and haunted Elsewhere.
