Carol watches in terror and shock as Lucy hacks the two bodies to pieces. Lucy is declared insane and sent to an asylum, where she endures traumatic shock treatments for her mental breakdown.The narrator of the flashback is revealed to be Carol, now a young woman. It is twenty years later, and Carol is opening up about her past to her boyfriend, Michael Fields.
