Susan has inherited Death's perfect memory, which includes the ability to ""remember the future"", and an instinctive knowledge of the nature of Death's work, which gives her considerable assistance during her brief time doing her grandfather's job in "Soul Music". In order to keep her from going insane, her mind represses much of the knowledge provided by this memory, but even so, parts of it occasionally permeate her consciousness, generally manifesting as premonitions or intuitive insights into forthcoming events. In "Hogfather", she states that the fragmented nature of such foresight makes the power largely unhelpful.
