of her time with the Doctor consciously. This causes her strange dreams, and makes her work suffer. An encounter with the Third Doctor makes the memory blocks permanent, but she ultimately never reaches her full potential. Padbury has appeared in Doctor Who audio adventures from Big Finish Productions, first as a character other than Zoe in the full-cast audio Davros, and then as Zoe in Fear of the Daleks, part of the "Companion Chronicles" talking book series. The latter story portrays an older Zoe having detailed dreams of her adventures with the Doctor; she suspects that something is blocking her memory, but she does not know what, and is seeing a psychiatric counselor in an effort to understand the "dreams". She has returned as Zoe in several more Big Finish plays such as Echoes of Grey and her second Companion Chronicle, Prison in Space, based on an unmade TV story. Echoes of Grey and subsequent follow-up stories, The Memory Cheats and The Uncertainty Principle depict Zoe being essentially taken prisoner by an unnamed Company whose experiments in creating a new form of life were disrupted by the Doctor, Jamie and Zoe- the TARDIS arriving on Earth a few decades in Zoe's future- in Echoes of Grey, subsequent stories seeing the Company arresting Zoe's older, contemporary self on trumped-up charges to try and provoke Zoe into unlocking her lost memories of her time with the Doctor so that they can harness the secret of time travel. This comes to a head in the audio Second Chances when Zoe has a 'flashback' of the destruction of a space station that will actually take place a few days in the future from her current point in time, allowing Zoe to interact with her past self as she tries to change her history and prevent the station's destruction. Although this part of her plan fails, the audio ends with Zoe using a computer virus that has mutated to attack physical matter to destroy the Company and escape, although her mental state and memories of her time with the Doctor are still lost. An older Zoe is reunited with the Doctor in his sixth incarnation in Legend of the Cybermen, where she returns to the Land of Fiction after she is nearly converted by the Cybermen after leaving the Doctor, her attempt to trap the Cybermen in the Land resulting in the universe being endangered
