Offered a chance to travel with the Doctor again , she declined and returned to her life in Los Angeles in 2009 .

Oblivious of the fact , Yrcanos died seven days after the wedding , having been poisoned by Mandrake . When the Doctor came to attend Peri ' s wedding , Mandrake had him thrown into the cells , where he remained for five years as Mandrake used Peri ' s body to prepare for a coup of the various kingdoms . However , since Peri was sterile due to her spectrox poisoning , none of the other rulers would marry ' Peri ' as she would be unable to continue the royal line . After five years , Mandrake poisoned Peri ' s own body , wanting to force the Doctor to transfer his mind to the body of princess Dirani of Hurn in exchange for a cure . Eventually , after swapping bodies with Peri in order to force the mind parasite into submission with his greater strength of will , the Doctor managed to restore her real consciousness and save her life with an antidote he had prepared during his imprisonment . Following this , Peri rejoined the Doctor on his travels . ( AUDIO : " The Widow ' s Assassin " ) Together with the Doctor , she visited the Dalek - occupied Scotland in 2163 , where she was briefly infected by a Varga plant before she was cured in a Dalek facility . ( AUDIO : " Masters of Earth " ) . At the College of Advanced Galactic Education , where they encountered the Rani in her new incarnation , Peri was subjected to another body - switching experience when an elderly Countess was transferred into her body , but listening to an audio diary Peri had made earlier forced the Countess to realise that what she and others were doing was wrong . She also gained an honorary degree in Botany . ( AUDIO : " The Rani Elite " ) Other . The other permutations of Peri , and the reasons for their creation , were not specified by the Time Lord . ( AUDIO : " Peri and the Piscon Paradox " ) Undated events . At some point , Peri was taken to the Black Archive by UNIT to have her record as a companion of the Doctor taken , her memories of the visit were subsequently erased and she was sent on her way . ( TV : " The Day of the Doctor " ) Mysteries and discrepancies . During the Doctor ' s fifth incarnation , Peri spent a year as a guerrilla fighter while separated from the Doctor , who meanwhile headed a military organisation known as the Alliance . ( PROSE : " Warmonger " ) The length of time that Peri spent with the Doctor was unclear . Some accounts suggested her travels with the Doctor occurred over the space of months , whilst others stated that at least " a couple of years " had passed for her between her first encounter with Jamie McCrimmon and her second . ( COMIC : " The World Shapers " ) As noted above , she was also separated from the Doctor for as long as a year on one occasion ( PROSE : " Warmonger " ) and two years on another . ( AUDIO : " The Kingmaker " ) Alternative timeline . In an alternative timeline created by , she met the Seventh Doctor and Ace while she was travelling with the Sixth Doctor . The Seventh Doctor was melancholy when he saw her again , telling his younger self that he had never gotten used to time travel leading to his being reunited with old friends . However , Peri got along well with Ace . She was surprised that Ace referred to the Seventh Doctor as " Professor " but was amused when she referred to the Sixth Doctor as " Joseph , " a reference to the musical " Joseph and the Amazing Technicolor Dreamcoat " . She lost all memory of this encounter when the proper timeline was restored . ( AUDIO : " The Light at the End " ) Behind the scenes . BBV Productions . Using her actual English accent , Nicola Bryant played " Miss Brown " ( who was never actually referred to by name on - screen ) , an obvious analogue to Peri , in three BBV Productions videos in the series : " Summoned by Shadows " , " More Than a Messiah " and " In Memory Alone " . Later videos in the series would make clear that the " Stranger " series did not take place in the " Doctor Who " universe and that Peri and Miss Brown had no connection with each other . Bryant also played Elenya " Ellie " Brown , the girlfriend of Colin Baker ' s character , TV weather forecaster Arnold " Arnie " Davis , in another BBV production , the non - " Doctor Who " " The Airzone Solution " . Longevity . Counting audio and televised adventures together , Peri effectively shares the longest - serving companion title — both in terms of number of stories and recorded time — with Ace . As they are tied , the title essentially alternates as new stories are released . Her nearest rivals are Jamie McCrimmon , Charley Pollard and Nyssa . Of these , only Jamie and Nyssa appear to be in active use past 2010 . Nyssa ' s appearances are considerably more frequent than Jamie ' s so she represents the only potential threat to Peri and Ace ' s record - breaking number of appearances . While she clearly eclipses the amount of time Sarah Jane Smith has been seen or heard as a " companion " , Peri is easily outpaced by the " character " of Sarah , due to Sarah ' s latter - day appearances as a solo character . American accent . While Peri is supposed to be an American , her English accent often slips and her American accent wanders between different regional accents . She sometimes uses phrases and pronunciations that Americans would not use , such as " lift " instead of the American " elevator " . Indeed , the " Attack of the Cybermen " DVD commentary maintained that it was mandated that Peri only use British slang to avoid confusing the audience . This may have worked for the " British " audience but , as Peter Davison pointed on on the DVD commentary for " Planet of Fire " , it had the opposite effect on American viewers . They could spot Bryant ' s fake American accent — or , really , " any " British actor ' s attempt at American — with ease . This was one of the principal reasons that Davison fought hard against adding an American companion to the show . This idiosyncrasy of language did not end with the TV series , as it can be heard in several audio dramas also . According to Nicola Bryant on the DVD commentary for " Planet of Fire " , there was an active effort to cover up the fact that she was not , in fact , American . She recounted there how John Nathan - Turner insisted she use her American accent when making public appearances or appearances that could have been monitored by the press . At least during the recording of her earliest serial s , like " Planet of Fire " , she was even required to use the American accent when she broke character between takes . It ' s unclear how long this obfuscation lasted , but evidence for the subterfuge can be heard on a clip from " Breakfast Time " broadcast the day the first episode of " The Twin Dilemma " aired . During the interview , the interviewer asserted that as a " little girl in America " Bryant used to watch " Doctor Who " and dream of being a companion . Bryant , who used only a very mild English accent during the interview , failed to correct the interviewer or to even look as though the interviewer had made an error . Near the end of the 1984 production block — which is to say after the recording of Season 22 , but probably slightly before its airing — Bryant gave a radio interview in which she used her natural British accent . ( AUDIO : " Doctor Who at the BBC Volume 3 " ) Relationship with her stepfather . The idea of Howard Foster sexually abusing Peri is one never considered by the production team on " Planet of Fire " and does not have resonance in audio and print literature beyond the novel " Shell Shock " . Nicola Bryant says that the idea , as envisioned by Fiona Cumming , Dallas Adams and her was to suggest that she and her stepfather had an appropriate but friendly relationship . Indeed , according to Bryant , Peri much preferred the company of Howard to that of her mother . ( DCOM : " Planet of Fire " ) However , the character of Peri ( or at least one aspect of Peri ) was still destined for an abusive relationship as revealed in AUDIO : " Peri and the Piscon Paradox " . whoisdoctorwho . co . uk . The website whoisdoctorwho . co . uk had a list of sightings of the Doctor from which people had ostensibly been submitting to Clive Finch , a conspiracy theorist character from the television story " Rose " . An entry credited to Peri herself — evidently having access to early 21st century Earth ' s Internet — mentions that the Doctor had " walked into my life one day , and right out of it " and that she wanted to get back in touch with him .
