Tegan Jovanka

Tegan Jovanka was an Australian air stewardess trainee who wandered into the Fourth Doctor's TARDIS when she mistook it for a genuine police box. She quickly became embroiled in the events surrounding his regeneration and soon found herself a somewhat unwilling passenger of the Fifth Doctor. She was one of the few companions to have parted company with the Doctor, only to return for a significant number of adventures.

She was joined in her travels by Adric, Nyssa, Vislor Turlough, Kamelion and, briefly, the Brigadier. She also once played the Game of Rassilon in the Death Zone on Gallifrey, during which she met the First, Second and Third Doctors, along with Susan Foreman and Sarah Jane Smith.

Her relatively long tenure of service onboard the TARDIS belied an ambivalence about wishing to travel with the Doctor. Until her final glimpse of the TARDIS, she vacillated between wanting to stay and wanting to go. She returned to work as an air stewardess in 1985.

Early life
Tegan was born in the city of Brisbane on 22nd September 1960. (BFA: The Gathering) In her youth, she spent some time in Caloundra, north of Brisbane. (PDA: The King of Terror) She moved to London to pursue a career as an air stewardess in 1981. (DW: Logopolis)

Her mother was still alive in 2006. (BFA: The Gathering)

Travels with the Doctor
On 28th February 1981, Tegan's aunt drove her to Heathrow Airport for Tegan's first day as an air stewardess--but her car broke down on in the London Borough of Barnet. Seeing what she thought was an ordinary police box, Tegan tried to call for help. Instead, she discovered the huge interior of the Doctor's TARDIS. Astounded by the console room, like others before her, she ventured off into its depths.

The Fourth Doctor and Adric, not knowing she was on board, dematerialized for Logopolis, in an effort to get the Logopolitans to perform the complex calculations needed to restore functionality to the TARDIS' chameleon circuit.

The TARDIS crew discovered that they had an accidental passenger. However, returning her to her rightful time and place became a secondary concern, once the Doctor became aware that the Master was attempting to create instability in the universe by manipulating Logopolis. Tegan became embroiled in the Doctor's cause once she discovered that the Master had in fact killed her aunt.

When she became stranded on a crumbling Logopolis with the Doctor, she became one of the few companions to travel in the Master's TARDIS. The trio journeyed to Earth's Pharos Project, which could stop the rampant entropy the Master had unleashed upon the universe. Once there, she witnessed the Doctor's near-fatal fall from the Project's radio telescope, and his subsequent regeneration. (DW: Logopolis).

After this, she did not abandon the Doctor, even though she was ostensibly in her proper time and place. Perhaps seeing that she would be facing some sort of charge for criminal trespass, she decided to throw her lot in with Nyssa, Adric and the newly-regenerated Doctor. She and Nyssa became critical to the effort to stabilize the Doctor's difficult regenerative process. Amongst other accomplishments, she became a temporary pilot for the TARDIS, and saved it from being destroyed when it tried to travel past the Event One horizon. Her success was tempered by the fact that the Master had manipulated the outcomes. (DW: Castrovalva)

On the planet Deva Loka, Tegan was taken over by the Mara. (DW: Kinda) She later displayed at least a basic appreciation for cricket and a talent for dancing the Charleston. (DW: Black Orchid).

She also encountered the Cybermen, and became angry with the Doctor's refusal to use the TARDIS to go back in time and rescue Adric from death. (DW: Earthshock)

Tegan was left behind at Heathrow Airport in her home time due to a misunderstanding (DW:Time-Flight). Later, after losing her job with the airline, she returned to the Doctor's side to search for her lost cousin, Colin Frazer, in Amsterdam. (DW: Arc of Infinity)

On Manussa, the Mara once more possessed her, and the Doctor claimed to have defeated it permanently. (DW: Snakedance)

Back on Earth, Tegan met two different versions of the retired Alistair Gordon Lethbridge-Stewart who was teaching at a public school whose student population included the mysterious Turlough. She displayed a talent for character assessment when she immediately warmed to the former, while distrusting the later. (DW: Mawdryn Undead).

Nyssa's decision to stay on Terminus to care for the victims of Lazar's disease affected Tegan emotionally (DW: Terminus).

Tegan had a brief romance with the Eternal, Marriner, a being who didn't love her so much as want to live vicariously through her emotions. During the same adventure, she saw Turlough turn away from evil and reject the Black Guardian. (DW: Enlightenment) Eventually, the carnage around the early phase of the Dalek civil war proved too much for her to bear. She bid an emotional, and somewhat accusatory, farewell to the Doctor and Turlough in 1984 London and ran off before the Doctor could respond. Even so, she seemed to reverse her decision. She ran back to where she thought the TARDIS would be, only to find that the Doctor had already departed. (DW: Resurrection of the Daleks).



Life after the Doctor
After leaving the TARDIS for the second time, Tegan, after apparently working as an air stewardess for some time, returned to Brisbane and took over her father's animal feed company. In September 2006, Tegan was briefly re-united with the Fifth Doctor, who discovered that she had been diagnosed with an incurable brain tumour. (BFA: The Gathering)

According to research conducted by Sarah Jane Smith, Tegan was still alive as of 2010, campaigning for Aboriginal rights. (SJA: Death of the Doctor)

Personality
Tegan was stubborn, loud, and direct. She once described herself as "just a mouth on legs" (DW: Earthshock). While she often bickered with her fellow travellers, her intrinsic honesty and morality proved useful. The Doctor once noted that these qualities made her a good coordinator. (DW: Castrovalva). She was also more likely to detect a threat to the Doctor's safety than her fellow companions. (DW: Castrovalva, Mawdryn Undead)

Of her fellow travellers, she was likely closest to Nyssa, whose nature was in many ways the precise opposite of her own. Though morally indignant at the Doctor's apparent unwillingness to save Adric's life (DW: Earthshock), she was genuinely saddened when Nyssa left. (DW: Terminus)

On Deva Loka, Tegan argued with Adric after he suggested she was too weak-minded to defy the Mara and therefore the ensuing chaos was her fault. (DW: Kinda) However, she also showed concern for Adric's wellbeing when he was captured and tortured by the Master. (DW: Castrovalva)

Although she seemed to despise violence (DW: Resurrection of the Daleks), she would resort to it under certain circumstances. When the Master threatened the Doctor, Tegan immediately threw a knife at him. (DW: The King's Demons)

Despite the strong front that she adopted, she was actually quite insecure. This manifested itself most strongly in her inability to firmly decide whether she wanted to stay onboard the TARDIS. Even when she seemed most resolute in her determination to go, she quickly reversed herself. On both occasions when she left the TARDIS, it was the Doctor's act of dematerializing the TARDIS — and not her own unwavering desire to go — which firmly separated the two. (DW: Time-Flight, Resurrection of the Daleks) Seeing through Tegan's false bravado, the Doctor encouraged her to find her inner strength with the words, "Brave heart, Tegan."
