Truth-drugged Marlena 'cheerfully' confesses to further murders, actually taking pride in the devious tricks and her abuse of medical skills to end the lives of the witnessing relatives' loved-ones. She was motivated by covering her tracks, and later, even ambitious to 'out do' the most famous serial killer. It takes all of Lucas' strength to handle both Sami, slowly coming to grips with her beloved mother's murderous guilt, and his own mother Kate's fury at their bond - especially when Will enters and hears his grandmother's fate, which grandfather Shawn considered inconceivable a minute ago. Rex scolds Mimi for not telling him the truth about Cassie's death, but arrives in time to share in Kate's horror and sweetly offers to bond with their birth-mother as Cassie will now be unable to, forever. Shawn and Belle shiver to hear that she even meant to stab him to death.
