Theory:Timeline - Thirteenth Doctor

This page lists appearances of the Thirteenth Doctor 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 that for each novel, comic, audio or television series, their published, broadcast or numbered order is the order they occur in.

The layout of this timeline is in part based on the observations on Doctor Who - The Complete Adventures, as well as Lance Parkin's AHistory and other sources that allow us to make observations, such as Doctor Who Reviews, and Clive Banks databanks. None of these sources should be used solely as a source or considered a "true" timeline for stories.

Companions
After being asked to refer to him as such in TV: The Woman Who Fell to Earth and TV: The Ghost Monument, Ryan is able to bring himself to call Graham his granddad in TV: It Takes You Away. Thus, any story where Ryan identifies Graham as his grandfather must take place after It Takes You Away, and stories that do not feature Ryan identifying Graham by his name or title can take place at any point. However, entries such as TV: Spyfall and COMIC: The Power of the Mobox show that Ryan does call Graham both by name and by "granddad" interchangeably.

When Team TARDIS take one of their breaks from their travels in TV: Can You Hear Me?, the Doctor is shown preparing to skip ahead to their next meeting in favour of traveling alone for a while, with the implication she does this the majority of the time, as she acts unaccustomed to not having a companion with her.
