Other episodes such as "Human Nature"/"The Family of Blood", set in 1913, depict the racism of an earlier era (Edwardian era). For Orthia, the few "Doctor Who" serials that explicitly depict racism "are remarkable by their presence: they carry rhetorical power because they are so rare in "Doctor Who"." In "Human Nature", in addition to the racist jibes of private school boys, "we bear witness to how things have changed, when a white nurse refuses to believe that Martha is a medical student in the future, saying, "Women might train to be doctors, but hardly a skivvy and hardly one of your colour."" When the TARDIS crew are nationally branded as terrorists in "The Sound of Drums", the Master (Simm) says that the Doctor's current companions "tick every demographic box" – referring to Martha's gender and ethnicity and Jack's sexual orientation. He later refers to Jack (Barrowman) and Martha as "the girlie and the freak", adding to the insult by claiming he is not sure which is which. Episodes set in the future, Orthia notes, are more often than not inclusive and "cosmopolitan" projections of societies which are as multi-racial (though not multi-ethnic) and sexually liberal as the present, if not more so. In 2009, Martha was listed among the top 20 Black Sci-Fi Icons by "Entertainment Weekly".
