Tegan Jovanka

Tegan Jovanka was, briefly, a companion of the Doctor during his fourth incarnation and for a longer length of time, his fifth incarnation.

Early life
Australian by birth, Tegan was born in the city of Brisbane on 22nd September 1960 (BFA:The Gathering). She moved to London and decided to pursue a career as an air stewardess (DW: Logopolis).

Travels with the Doctor
On 28th February 1981, Tegan was on route to Heathrow Aiport to start her new job with Air Australia with her aunt, Vanessa. She entered an apparent roadside police box on the Barnet Bypass to seek help, not knowing that it is actually a series of nested TARDISes including Doctor's and Master's. The Master, at that time, killed her aunt using his Tissue Compression Eliminator. She was present when the the Doctor fell from the Pharos Project radio telescope and regenerated into his fifth incarnation (DW: Logopolis).

After she joined the crew of the TARDIS by accident, the Doctor took her to several times and places in an effort to return her home. On the planet Deva Loka, Tegan was taken over by the Mara. (DW: Kinda) She was deeply upset by the death of Adric in Earthshock.

Tegan was left behind at Heathrow Airport in her home time due to a misunderstanding (DW:Time-Flight). Some time after, by which time she had lost her job with the airline, she returned to the TARDIS in the subsequent adventure while she had gone to Amsterdam to search for her lost cousin, Colin Fraser (DW: Arc of Infinity.

With justification, she suspected a new arrival, Turlough of bad intentions for joining the crew of the TARDIS (DW: Mawdryn Undead, Terminus (TV story)). Nyssa's decision to stay on Terminus to care for the Lazars affected her emotionally (DW: Terminus).

Eventually, the carnage surrounding the early phase of the Dalek civil war prove too much, and she bids an emotional good-bye to the Doctor and Turlough (who by this time had reformed) in 1984 London (DW: Resurrection of the Daleks).

More than twenty years after she first met him, she re-united with "her" Doctor again briefly. (BFA: The Gathering)

Personality
Tegan ws stubborn, loud, and direct, with a no-nonsense manner and not afraid to speak her mind. She described herself as "just a mouth on legs" (DW: Earthshock). While she often bickers with them as well as with the Doctor, her strength of character keeps them together and her loyalty to her fellow crewmates is unquestionable. She was close to Nyssa, and is especially saddened when she left (DW: Terminus) The Doctor notes that she is a good coordinator, and often encouraged her with the words, "Brave heart, Tegan." Despite the strong front she adopted, her adventures with the Doctor, both thrilling and terrifying, eventually take a psychological toll.

Skills and talents
She was able to speak one of the many Indigenous Australian languages fluently and to make sketches (DW:Four to Doomsday).

Relatives
Other than Aunt Vanessa (DW: Logopolis) and Colin Fraser (DW: Arc of Infinity) and an uncle named Andrew Verney, who lived in the small English village of Little Hodcombe (DW: The Awakening).

Other possibly non-canonical information
One account shows that, while working again as an air stewardess, Tegan was accidentally transported by the Doctor into his TARDIS where she helped him and Gareth Jenkins (DW: A Fix with Sontarans).
