Lucie Miller

Lucie Miller was a companion of the Doctor in his eighth incarnation.

Meeting the Doctor
A strong-willed Northern lass, Lucie was initially an unwilling passenger in the Doctor's TARDIS, having been placed with the Doctor as part of a "Time Lord witness protection programme." Lucie told the Doctor that the Time Lords had placed her in his care because she had seen something important; she didn't know what. Her initial attitude towards the Doctor is disdainful, but she recognizes that he's "about saving worlds". (BBCR/BFA: Blood of the Daleks)

Travels with the Doctor
Lucie unexpectedly encountered her 'Auntie Pat', Patricia Ryder, the drummer from a band called Methylated Spirits, in 1974. As this was over a decade before Lucie is born, Pat was sceptical, but grew to like her. Lucie's mother was named Mary. (BBCR/BFA: Horror of Glam Rock)

After some time with the Doctor the truth was revealed; the Time Lords learned that the Celestial Intervention Agency had been tracking a woman who would be a future dictator within Europe, and attempted to alter her past to prevent this. When Lucie applied for a job which was part of another CIA plot, the primary faction of Time Lords placed 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, was the actual future dictator, and the Time Lords had either been tricked by the CIA or simply made a mistake.

Lucie and the Doctor bumped into Karen and the Headhunter in 19th century Sweden, and stopped their plan of destroying a pocket universe. (BFA: Grand Theft Cosmos)

Lucie met her Auntie Pat again, this time in 1984. Pat was running a hotel in the Lake District with her husband, Trevor. This confused Lucie as she knew nothing of her Uncle Trevor. It was revealed that Trevor was in fact a rehabilitated Zygon, and was being pursued by his former colleagues who kidnapped Lucie and created a copy of her. These Zygons killed Pat but were defeated by Trevor and the Doctor. The Doctor told Lucie of Pat's death and the Web of Time, reasoning how Pat could die but Lucie could still have met her. Unknown to Lucie, the Doctor found Trevor, who had survived the explosion that defeated the Zygons, and Trevor shifted his shape into that of Pat, vowing to remain as her and live her life for her. The Doctor promised not to tell Lucie that the Auntie Pat she knew was never in fact her. (BFA: The Zygon Who Fell to Earth)

After defeating the resurrected Morbius on Karn, the Doctor fell from a balcony on Morbius' palace. Lucie found there was no sign of him and presumed he was dead. The Time Lords returned Lucie home to Blackpool, some time later, in the middle of the night, Lucie was confronted at her home by an armed Headhunter. (BFA: The Vengeance of Morbius) The Headhunter abducted Lucie using a time bullet and took her to the planet Orbis in the Doctor's TARDIS, where, shortly after defeating the Headhunter, resumed her travels with the Doctor in the TARDIS. (BFA: Orbis)

Leaving the Doctor
Some time after, Lucie and the Doctor helped to save the universe from an invasion of the Eight Legs in 2015. (BFA: Worldwide Web) Lucie then asked the Doctor to take her home to spend Christmas in Blackpool in 2009. Lucie then found out the truth about her Auntie Pat being a Zygon, a truth that forced Lucie to decline the Doctor's offer to continue travelling with him. (BFA: Death in Blackpool)

Travels with the Meddling Monk
Later, Lucie began travelling with the Meddling Monk, apparently after responding to an advert he placed in 2010 for a companion. (BFA: Situation Vacant) She encountered the Doctor's companion Tamsin Drew at the Abbey of Kells in 1006, but did not meet the Doctor face to face. He, in turn, had no idea who she was, as she was disguised as a monk named Lucianos at the time. (BFA: The Book of Kells)

Reunion with the Doctor
After Lucie voiced her disapproval of the Monk's interference in the timeline, the Monk had abandoned her on Deimos whilst a human base on the moon was about to be destroyed. (BFA: Deimos) The Doctor managed to rescue Lucie and the Doctor decided to give Lucie another Christmas with him to make up for the one he had ruined for her. (BFA: The Resurrection of Mars)

Personality
Lucie had a morbid fear of crocodiles. (BFA: The Skull of Sobek)
