Was Tess behind Jessicas haunting of Dorian?
Maybe, maybe not. Although the writers, during Jessicas 2005 DID s/l, did fleetingly look back on Jessicas previous unconscious haunting/attempted murder of Dorian after having lost baby Megan, they never absolutely concluded that it had indeed been Tess who was behind that ordeal. So its really up to the viewer to decide if it was Tess or not. Personally, I dont think so. From what I recall of it, Jessica seemed to be under more of a psychosomatic trance when she was haunting Dorian. It didnt read like Tess at all, but thats just my opinion.
