John Roberts is the father who tries desperately to hold things together. He works a lot and at odd hours in an effort to distance himself emotionally from his children though he loves them with all his heart. It's very difficult for him to face the pain that they have suffered through the loss of their mother and he believes that providing them with a good income and a stable can somehow make up for his inability to connect on an emotional level. With the death of his son Tony, he falls further into his program of denial and never really mourns his loss.
The events that unfold when Redbush and the paranormal research team join the case are exactly what he needs to give himself permission of feel again.
