Farewell, Dr. Guthrie.
I agree, Lydia, David Radcliffe was disappointing. This is all we get to hear from him, even though the ep seems to end just partway through his testimony. What we can read into all this is that DR didn't go off to wonderful Phoenixland as a result of the flames, or he probably wouldn't have been a ghost obsessing on the burning. I know it's such torture that you'd want to warn someone even if a happy ending lay on the other side, but after a happy life in paradise then years of death, it would all seem less urgent. My guess is that DR knows that the boy involved in Laura's rebirths just burns.
How can DR, a ghost from elsewhere, appear at a seance designed for Josette, occupant of the house, to communicate better? Does DR's ghost hang around with Josette, did she take him under her wing? Did she run into him at the Stockbridge crypt or Radcliffe grave?
Perhaps we're hearing from the soul of old, human, untransferred David Radcliffe, who died in flames, who was then recreated as a new David Radcliffe, like a sort of clone. Old DR haunted, while new DR went off with Laura to the other world. In that case, the meaning of the warning is ambiguous, if it was a warning. Maybe he was pulled in by the seance, and forced to re-experience the event they were interested in, and that's it. If all this is right, could there be a soul of Laura Murdoch Radcliffe hanging around too, and a Laura Murdoch Stockbridge, whom they could talk to?
