Bilocation is an ancient phenomenon. It is claimed to have been experienced, and even practiced by will, by mystics, ecstatics, saints, monks, holy persons, and magical adepts. Several Christian saints and monks were adapt at bilocation such as St. Anthony of Padua, St. Ambrose of Milan, St. Severus of Ravenna, and Padre Pio of Italy. In 1774, St. Alphonsus Maria de'Ligouri was seen at the bedside of the dying Pope Clement XIV, when in fact the saint was confined to his cell in a location that was a four-day journey away.
Bill: But we don't know where Emily is.
Esther: She was in Leeburg last night. That's where the fire was, wasn't it?
Dr. Parks: Mrs. Quentin please listen to me for a moment. If it's true that you know what your sister's thinking.
Esther: If it is true! I swear to you that it is true.
Dr. Parks: And working on the theory that you have a sister named Emily.
Esther: You don't believe that.
Bill: Well it's hard to believe, you never mentioned her before.
Esther: Would you believe me if Emily called me on the phone tonight. I can will her to call me.
Esther: I can will HER to call me. (turning to the Doctor) I can.
Dr. Parks: If you can do that, then will her to stop setting fires.
Esther: But I can't do that Dr. Parks, don't you think I haven't tried. Don't you think I'ver really tried!
John Newland: (closing dialogue) The phenomenon of Bi-location, the power for a person to be in two places at once, has been reported many times. In a sense the one entity becomes two. The second is sometimes called "the etheric double", in this instance Esther Quentin may have subconsciously been aware of the truth, that the evil Emily was actually her other self and so deliberately consigned both entities to the flames.
