Diana Goddard

Diana Goddard (usually just called Goddard) was the highly efficient and ruthless personal assistant to Henry van Statten. Over the course of just one day, her career path went from replacing the old assistant to taking over GeoComTex, van Statten's company.

Goddard had a sardonic sense of humour, much like her employer. She found the Democratic Party "funny" and hoped that they would win the next Presidential election, an event over which van Statten implied he had control.

Goddard told the Ninth Doctor to "shut it" before recognising him as an ally. Van Statten accorded her a rare degree of respect. After the Doctor and Rose Tyler had destroyed the Dalek let loose in the Vault, Goddard orchestrated a corporate palace coup of sorts and took over from van Statten, demonstrating her ruthlessness by ordering his memory wiped and her former boss dumped on a street corner in some city starting with the letter "S".

Behind the scenes
In the online game The Last Dalek, which presents an alternate version of the events of Dalek, Diana Goddard does not appear, but she has an entry in the Dalek's memory files. She is described as "Female subject. Age 25. American. Working her way to Van Statten's upper ranks. Calculating and professional."
