Charles Blake, Evelyn Napier's boss, served during the Great War alongside Tony Gillingham on the HMS Iron Duke under fleet commander John Jellicoe. At Downton Abbey, the handsome government man on a mission to assess the post-war viability of England's great estates immediately gets off on the wrong foot with Mary. Revealing himself to be prejudiced against the aristocracy, he seems like a humorless enemy of all that Mary holds dear. But could the icy sparring between Blake and Mary eventually generate heat? And could Evelyn Napier again rue the day he brought an attractive friend along to Downton Abbey?
