There is still some controversy over the best way to interpret the final scenes of "The Human Factor" and their implication for the fate of Janette DuCharme. Janette was a regular character in Seasons One and Two, but she left Toronto shortly before the start of Season Three. Flashbacks in "The Human Factor" tell her activities thereafter: she had moved to Montreal, fallen in love with an arson investigator named Robert McDonagh, and then turned mortal from the shock and grief she felt when he was murdered. She returned to Toronto in pursuit of the man she blamed for his death.
