Companion reign – 1965 – 66

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 (played by Aidrienne Hill) was the slave girl (and spy) of the Trojan princess Cassandra, who the First Doctor met during The Myth Makers – 1965.

During the Greek sacking of Troy, Katarina helped an injured Steven, escape into the Tardis but was stuck as the Tardis left Troy. The simple Katarina did not take well to time-travelling, believing that they had infact died – and gone on to the Trojan afterlife.

Katarina accompanied the first Doctor and Steven, for a short time but in The Dalek’s Masterplan, she gave her life to save the Tardis crew; by blowing herself (and a convict called Kirksen) out of an airlock into space to stop a Tardis hijacking.

Dorothy “Dodo” Chaplet

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 had met – prior to meeting Dodo.

Dodo was the fourth female human to travel with the Doctor, (after Susan, Barbara and Vicki) and the Doctor was particularly drawn to her; as Dodo reminded the Doctor of Susan.

Dodo was an impressionable young girl and wasn’t particularly bbright or gifted. However, she was progressive and modern, having been raised in Swinging 1960’s London – and took to time-travelling well.

Her 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 with her.

So when the Doctor visited 1880’s Tombstone, Arizona in The Gunfighters – 1966; Dodo had already visited – in an earlier time period. Therefore, Dodo was well acquainted with American culture and custom.

It was Dodo, who infected the unfortunate future human race (on a starship enroute to a new homeworld), with the cold virus in The Ark – 1966. Humans had long since banished all germs and as a result, they had no immune response – so were struck down terrribly 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.
