Katarina : “STOP! Without the Doctor we’ll never reach the place of perfection….” – The Myth Maker’s – 1965
Dodo : “Wait a minute, if this isn’t a Police Box, what is it? and who are you?” – The Massacre of St Bartholomew’s Eve – 1966
Katarina
Katarina (played by Aidrienne Hill) was a Trojan slave girl and spy of the princess Cassandra, whom the First Doctor met during The Myth Makers – 1965; which took place, during the Greek sacking of Troy.
Katarina helped an injured Steven, escape into the Tardis but was herself trapped; as the Tardis left Troy.
Katarina being a simple human-being, did not take well to time-travelling, believing that they had all infact died and gone to the Trojan afterlife.
Katarina accompanied the Doctor and Steven, for a short time. However, in The Dalek’s Masterplan, she gave her life to save the Tardis crew. Katarina blew herself – and an escaped convict called Kirksen; out of an airlock into space to stop a hijacking.
Dodo
Dorothea “Dodo” Chaplet (Jackie Lane) first met the Doctor in The Massacre Of St Bartholmew’s Eve – in London 1966. She was a descendant of Anne Chapolet – from 16th-Century France. Whom the Doctor and Steven met; prior to meeting her descendant Dodo in the 20th-Century.
Dodo was the fourth female human to travel with the Doctor, after Susan, Barbara and Vicki. The Doctor was particularly drawn to Dodo; as Dodo reminded the Doctor of Susan.
Dodo was an impressionable young girl and wasn’t particularly bright – or gifted. But she was very positive and upbeat.
Dodo was progressive and modern, having been raised in Swinging 60’s London and adjusted to the rigours of time-travelling.
Dodo’s early life was not detailed but she had grown-up in London, prior to moving to Paris to live with an affluent aunt; who schooled Dodo and travelled her.
So when the Doctor visited 1880’s Tombstone, Arizona in The Gunfighters – 1966; Dodo had visited herself – in a later time period. Therefore, Dodo was well acquainted with American culture and customs.
It was Dodo, who inadvertantly infected the unfortunate future human race (on a starship enroute to a new homeworld), with the common-cold virus;The Ark – 1966.
Humans had long since banished all germs – and as a result, had no immune response. So were struck down with this deadly new plague. The Doctor, Dodo and Steven were tried by the humans – as saboteurs for unleashing a biological agent.
After Steven left the Tardis, Dodo travelled alone with the Doctor – for a time. Where she met new companions – Ben & Polly in The War Machines – 1966, in a 1960’s London nightclub.
After having her mind taken over – by the WOTAN computer, to betray the Doctor. Dodo was sent to the country to recuperate and decided not to return.
Therefore, Dodo sent her Tardis key – to Polly & Ben; who upon returning it to the Doctor, ended up travelling in Dodo’s place; by accident.
