Lucie Miller

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

Meeting the Doctor
Lucie's mother was named Mary. A strong-willed Northern lass, Lucie was at first an unwilling passenger in the Doctor's TARDIS, having been placed with the Doctor as part of a "Time Lord witness protection programme." She told the Doctor 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 was disdainful, but she recognised he was "about saving worlds". (BBCR/BFA: Blood of the Daleks)

Travels with the Doctor
Lucie unexpectedly ran into her "Auntie Pat", Patricia Ryder, the drummer of a band called Methylated Spirits, in 1974. As this was over a decade before Lucie was born, Pat was sceptical, but grew to like her. (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 become a dictator in Europe, and wished 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 plots. In reality, a woman named Karen, who had been interviewed on the same day as Lucie, was the actual future dictator. The Time Lords had either been tricked by the CIA or had made a mistake. (BBCR/BFA: Human Resources)

Lucie and the Doctor bumped into Karen and the Headhunter in 19th century Sweden, and stopped their plan to destroy 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 Trevor. He was in fact a rehabilitated Zygon, 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. 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 really 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 no sign of him and assumed him dead. The Time Lords returned Lucie to Blackpool. Some time later Lucie was confronted at her home in the middle of the night by an armed Headhunter. (BFA: The Vengeance of Morbius) The Headhunter abducted Lucie with a time bullet and took her to the planet Orbis in the Doctor's TARDIS. Shortly after defeating the Headhunter, she 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 asked the Doctor to take her home to spend Christmas in Blackpool in 2009. She found out the truth about her Auntie Pat being a Zygon,. This made Lucie decline the Doctor's offer to continue travelling with him. (BFA: Death in Blackpool)

Travels with the the Monk
Lucie later travelled with the 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 under the name Lucianus 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, he abandoned her on Deimos when a human base on the moon was about to be destroyed. (BFA: Deimos) The Doctor rescued Lucie and she accepted the Doctor's offer of another Christmas with him to make up for the one he had ruined for her. (BFA: The Resurrection of Mars)

The Doctor took Lucie to the TARDIS, where they had Christmas dinner with the Doctor's family: Alex and Susan Campbell. After this, Lucie went to travel 22nd century Earth with Alex. (BFA: Relative Dimensions)

Lucie sent a distress message to the Doctor for help with a Dalek invasion of Earth. (BFA: Prisoner of the Sun) She lost her sight in one eye from the plague the Daleks used to limit opposition on Earth at the start of the invasion. (BFA: Lucie Miller) Lucie died after she detonated a bomb under the Dalek stronghold to stop the invasion. (BFA: To the Death)

Personality
Lucie was feisty, independent, hot-tempered and kind-hearted.

She had a morbid fear of crocodiles after watching Peter Pan in her youth. (BFA: The Skull of Sobek) Lucie's favourite music artists from her time were Scissor Sisters, Pink, Sugababes, Gnarls Barkley, Lily Allen, Gorillaz, Goldfrapp, OutKast and the Killers. (ST: Remain in Light)

Even though the Doctor was furious when the Time Lords ordered Lucie to travel with him, he grew fond of her and they became the best of friends. Lucie's relationship with the Doctor was similar to the relationship he would later have with Amy Pond in his eleventh incarnation. However, Lucie's faith in the Doctor changed greatly when she found he had been keeping secrets from her. She mistrusted him until she forgave him.

The Doctor was devastated by Lucie's death. It made him to change his ways for good. (BFA: To the Death)
