Though Spike and Dru had not been conceived as necessarily having to be either British or American, Landau chose to portray Drusilla with a Cockney accent in keeping with the characters' ""Sid and Nancy" analogy". Drusilla's physical appearance also drew from additional sources, such as supermodel Kate Moss and the 1990s heroin chic aesthetic. The character's backstory gives her ties to Buffy's boyfriend Angel (David Boreanaz), and it is gradually established over the course of "Buffy" and "Angel". A young psychic in Victorian London with a potential for sainthood, Drusilla was driven insane by Angel before he eventually turned her into a vampire. In "Angel", the character recurs both in the present-day narrative and in flashbacks which depict her adventures across Europe and Asia with Angel and Spike. After "Angel" ended in 2004, the character continued to appear in Expanded Universe materials in other media. Landau went on to co-write a two-issue "Drusilla" story arc for IDW Publishing's in 2009, continuing her character's storyline.
