Lucie Miller

Lucie Miller is a companion of the Eighth Doctor.

Described as a "strong willed northern lass," Lucie is initially an unwilling passenger in the TARDIS, having been placed with the Doctor as part of a "Time Lord witness protection programme." Lucie tells the Doctor that the Time Lords have placed her in his care because she has seen something important; she doesn't know what. Her initial attitude towards the Doctor is disdainful, but she recognizes that he's "about saving worlds". (BBCR: Blood of the Daleks)

Lucie unexpectedly encounters her 'Auntie Pat', Patricia Ryder, the drummer from a band called Methylated Spirits, in 1974. As this is over a decade before Lucie is born, Pat is skeptical, but grows to like her. Lucie's mother is named Mary. (BBCR: Horror of Glam Rock)

After several more adventures with the Doctor the truth is revealed- the Time Lords learns that the Celestial Intervention Agency have been tracking a woman who would be a future dictator within Europe, and alter her past to prevent this. When Lucie applies for a job which is part of another CIA plot, the primary faction of Time Lords place her with the Doctor to protect her from the effects of multiple exposure to CIA equipment. However in reality a woman named Karen, who had been interviewed on the same day as Lucie for the job, is the actual future dictator, and the Time Lords have either been tricked by the CIA or simply made a mistake.
