Olivia arranged for a threesome between herself, her husband Samir and Bo, and the three had a very energetic sexual interlude. It turned out that she chose Bo deliberately to determine whether she was strong enough to hire as an assassin. Olivia had become violently jealous of her husband's human lover, Jenny, and wanted her killed.
When Bo refused to kill Jenny, Olivia decided to go to Jenny's house and kill her herself. Bo intervened, and when Olivia tried to "sear (her) mind", Bo managed to reflect Olivia's gaze in a shiny toaster. Her own gaze seems to have driven Olivia mad.
She ran home, only to find Samir's headless body waiting for her. Now further maddened by grief, she ran to her sisters' home to hide, until Dyson and Hale came to retrieve her. Lauren cared for the deranged Olivia until she died later that day, still protesting her innocence in her husband's murder.
