This page lists appearances of Izzy Sinclair in the order in which she experienced them. This timeline is based upon observations of the Doctor Who universe and the events that occur during each of these stories. From these observations we have attempted to build a concise timeline. It is assumed, much like its TV story counterparts that for each novel or audio series their published/numbered order is the order they occur in. This does not apply to short stories which are often ambiguous about their placement. There are also many gaps between stories.
The layout of this timeline is in part based on the observations on Doctor Who Reference Guide and Doctor Who - The Complete Adventures, as well as Lance Parkin's AHistory and other sources that allow us to make observations, such as The Whoniverse, Doctor Who Reviews, The History of Doctor Who, The Discontinuity Guide, Clive Banks databanks, two Big Finish forums and the Divergent Universe forum. None of these sources should be used solely as a source or considered a "true" timeline for stories.
Travels with the Eighth Doctor Edit
Fight against the Threshold Edit
- Izzy meets the Eighth Doctor. After she helps him defeat the Celestial Toymaker, he offers her companionship, to which she gleefully accepts.
- On Izzy's first trip into the future, the Doctor follows an SOS to the Keep, where he is forced by Marquez to bond with Crivello's Cauldron so it can be sent off to form a new star system.
- The TARDIS is still recovering from the events of A Life of Matter and Death. Lured to Crivello's Cauldron at Icarus Falling, the Doctor and Izzy discover that Marquez was working for the Daleks, and become embroiled in the Threshold's plot to destroy the Daleks to acquire the secrets of a box with the Seal of Rassilon on it. During his endeavour, the Doctor's link to the Cauldron is severed.
- The Doctor and Izzy are summoned by Fey to an island in the Indian Ocean during 1939, where the Doctor injects himself with poison to defeat a Cucurbite, forcing Fey and Izzy to take him to Gallifrey, leading into The Final Chapter.
- Whilst his body heals on Gallifrey, the Doctor ventures into the Matrix, where he learns from Rassilon why he hired the Threshold. The Doctor also catches up with Shayde, leading into Wormwood.
- Having switched places with Shayde, the Doctor goes undercover in the Threshold, witnessing their destruction by the Pariah. Shayde is injured in the battle, but is saved from death when Fey bonds with him, becoming a singular entity, and returns to Gallifrey.
Controller of the Glory Edit
- The Doctor bumps into Grace, and discovers the fallout of his influence on her.
- The Doctor is beginning to notice the TARDIS's recent difficulties finding its destination. He and Izzy are joined by Kroton, a Cyberman with his emotions intact.
- According to the Master, the events of The Fallen, The Road to Hell and The Company of Thieves took place in the past few months. Landing on Paradost, the Doctor, Izzy and Kroton find Sato Katsura leading the Church of the Glorious Dead, and in the services of the Master in his bid to win the contest with the Doctor for the Glory, however, it eventually transpires that the contest is really between Sato and Kroton, with Kroton emerging the winning. With the power of the Glory, Kroton kills Sato, and undoes the Master's recent atrocities before placing him in imprisonment, which is presumably the Eye of Harmony, because Forgotten presents him escaping from the Eye of Harmony. Esterath also removes the Master's ability to influence the TARDIS, setting this after The Gallifrey Chronicles.
Final adventures with the Doctor Edit
- Izzy knows Fey, setting this after Wormwood
- Izzy mentions the events of Wormwood.
- On the Ophidius, the Doctor's green frockcoat is destroyed, and Izzy has her body switched with Destrii, who is apparently disintegrated before they can switch back.
- While Izzy deals with the fallout of the events of Ophidius, the Doctor replaces his destroyed frockcoat with a blue jacket.
- Izzy is kidnapped by Destrii's pursuers, leading into Uroboros.
- Set during Uroboros: Part 1, before the Doctor calls Shayde for help.
- Returning to Ophidius with Fey, the Doctor finds Destrii alive and forces her to accompany him in his search for Izzy, leading into Oblivion.
- Having been returned to her rightful body, Izzy makes peace with her identity and returns home to her adopted parents. Destrii kills her mother, and then departs her home world with her uncle, Jodafra, in a chronon capsule.
