This page lists appearances of Elizabeth Klein in the order in which she experienced them. This timeline is based on observations of the Doctor Who universe and the events in each of these stories. From these observations we have attempted to build a concise timeline. It is generally assumed, much like their TV story counterparts, that each novel, comic or audio series their published/numbered order is the order they occur in.
The layout of this timeline is based in part on the observations on Doctor Who Reference Guide and Doctor Who - The Complete Adventures, Lance Parkin's AHistory and other sources that allow us to make observations, such as DocOhoReviews, The History of Doctor Who, The Discontinuity Guide, Clive Banks Databanks, the Big Finish forums, The Whoniverse and The Divergent Universe forum. None of these sources should be used solely as a source or considered a "true" timeline for stories.
- At Colditz Castle during the Second World War, the Doctor and Ace are confronted by Elizabeth Klein, a scientist from an alternate timeline, who escapes her defeat as an anomaly.
- After reencountering Klein, the Doctor insists on her accompanying him on his travels so that he can keep an eye on her, knowing she will continue to pose a threat to history.
- Set immediately after A Thousand Tiny Wings. The Doctor is using the TARDIS interior from Doctor Who.
- After travelling together for a while, Klein takes her chance of revenge on the Doctor by stealing his TARDIS and abandoning him on the planet of the Vrill.
- After Klein left him on the Vrill homeworld, the Doctor found time shifting around him until he arrived in an alternate timeline created by Klein, where he remained a prisoner for three days. After Klein is erased from history by the Time Lords, the Doctor visits UNIT to find a different version of Klein now working there. The Doctor is beginning to show signs of ageing; his hair is depicted as tufts growing out of the side of his head.
- Set after Dominion, with the TARDIS control room having the Victorian parlour console room design from Doctor Who.
- Klein recalls the events of Daleks Among Us.
