Vicki Pallister

Vicki — infrequently known as Vicki Pallister (PDA: Byzantium!) and never as Victoria (DW: "The Powerful Enemy", BFA: 1963) — was a young woman the First Doctor, Ian and Barbara met soon after Susan was left behind on Earth. Having lost both her parents in relatively quick succession, she decided to join the three time travellers on their adventures. Once the two teachers left the TARDIS, she travelled for an extended period with Steven Taylor, before leaving the Doctor's side to marry Troilus and to take the married name Cressida.

Early life
Vicki was born on Earth. (DW: The Rescue) Her mother wanted to name her Tanni, but her father preferred Vicki. As a girl she lived in Liddell Towers on the South Circular Road in New London, where she enjoyed looking at the stars at night, though they were so faint they could hardly be seen. (PDA: Byzantium!) As a student of a 25th century school system, she studied medicine one hour a week. By the age of ten she had obtained certificates in medicine, physics, computers, chemistry, and other disciplines. (DW: The Web Planet) Vicki was also skilled at cutting hair. (DW: Galaxy 4) Her mother had died when Vicki was very young. Her father took a job in a new colony on the planet Astra, leaving Earth in 2493. The ship carrying the colonists, the UK-201, crash-landed on Dido. Most of the passengers survived the crash, but one night, unbeknownst to Vicki, Bennett murdered all the survivors other than her, as well as all but two of the native Dido people. (DW: The Rescue)

Joining the TARDIS
When the TARDIS landed on Dido, Barbara Wright used a flare gun to kill Vicki's "pet" Didonian Sand Beast, Sandy, thinking it a threat to Vicki. It took effort on the part of Vicki to forgive Barbara for this. Bennett pretended he could not move his legs while Vicki took care of him. When the Doctor discovered the truth and the Didonians came to take revenge on Bennett, she was left with nobody. The Doctor, perhaps because he missed his recently departed grand-daughter, asked Vicki to come with them, making her the first companion that the Doctor was seen to willingly invite to travel in the TARDIS. (DW: The Rescue)

Travels
Vicki was keen for adventure. She was often bored on the journeys to their destinations, and the less adventurous moments of their lives. When the travellers were staying at a villa near Rome she was disappointed that there was no adventure. Her innate sense of adventure was complemented by a sense of awe and wonder, and these never diminished during her travels. She was bursting with excitement when she glimpsed Nero, and the sight of Rome burning excited her. (DW: The Romans) It is no doubt these characteristics which reminded the Doctor of Susan. Whether teasing, or merely undiplomatic, Vicki had a knack of saying the wrong thing to Barbara, despite their close relationship. Right off, she said that Barbara Wright must be "about five hundred and fifty years old" as she came from 1963. (DW: The Rescue)

On Vortis, Vicki said that aspirin tablets were old fashioned – until she saw some in the Doctor's first aid kit she had never heard of them. She also offended Barbara by responding to her statement that the main subjects taught at her school were the 3 R's by asking if Barbara's school had been a nursery. (DW: The Web Planet) Vicki didn't know The Beatles played "classical music", and called 1960s New York City "ancient". (DW: The Chase)

Vicki's youth and spirit of adventure enabled her to save the travellers from danger by inciting the Xeron rebels to action whilst at the Space Museum. Using her considerable analytical and technical skills, Vicki reprogrammed the Morok armoury's computer to allow the rebels access to it, enabling them to fight. (DW: The Space Museum)

Despite her bravado, Vicki was terrified of heights. Escaping from the Mechanoid City, the Doctor had to blindfold her, and the travellers, with Steven Taylor's assistance, had to lower her the fifteen hundred feet by rope. (DW: The Chase)

Leaving the Doctor
It would appear that most of Vicki's skills and knowledge were based in science, but she also knew some history. When the travellers materialised on Earth during the Trojan War, she displayed her knowledge of Greek heroes and the Trojan Horse. While in Troy, Vicki called herself Cressida and met Troilus, a young Trojan. They fell in love, and Vicki left the Doctor to be with him. Their tale would later be written as a poem by Geoffrey Chaucer and as a play by William Shakespeare. (DW: The Myth Makers)

Behind the scenes

 * The production team had originally considered the older and more independent Jenny, from The Dalek Invasion of Earth, as Susan Foreman's replacement in the cast. Originally, Vicki had the more futuristic-sounding name Tanni. Before settling on Vicki, the production team thought of several other names, including Valerie, Millie, Tanni and Lukki. Earlier drafts of The Rescue bore the title Doctor Who and Tanni due to this.
 * A letter shown on the Mounting the Rescue documentary included with the DVD release of The Rescue says that two girls from Liverpool - Maureen O'Brien and Denise Upson - were screen tested for the role of Vicki on Monday, 14 September 1964.
 * The Past Doctors Adventure novel Byzantium! revealed Vicki's previously unknown last name which was never mentioned on screen in any televised episodes.
 * Vicki is one of several human characters featured in the series whose last names were never revealed on screen. Others include Ace, Polly and Mel, though, like Vicki, spin-off media provided last names.
 * A documentary on The Rescue DVD revealed that the producers wanted Maureen O'Brien to dye her hair black to make her resemble Susan more. Maureen refused and instead suggested the alternative of getting Carol Ann Ford back.
