Theory:Timeline - Multi-Doctor stories

From Tardis Wiki, the free Doctor Who reference

This page lists every multi-Doctor story in which two or more incarnations meet or appear in close proximity to each other in the order in which each incarnation of the Doctor experienced them, with an analysis of their state in the memories of the Doctor and any other applicable individuals.

Stories in bold indicate that the incarnation being focused on is the most recent incarnation in that story.

Timeline[[edit source]]

The Past[[edit source]]

An unidentified incarnation of the Doctor, who had been living under the Chameleon Arch identity of "Ruth Clayton", meets the Thirteenth Doctor, who has no recollection of this incarnation, but nonetheless identifies her as being in her past. The fact that the Thirteenth Doctor retains her memory of "Ruth" in following stories reinforces this notion.

In 1963, the First Doctor, considering what is to become of the Hand of Omega, is saved from an Imperial Dalek by the Seventh Doctor, who pushes him out of the way before collecting the TARDIS Instruction Manual, actually a piece of the Key to Time, which the First Doctor had dropped. Regaining his footing, the First Doctor remains unaware of both his would-be assassin and his saviour, believing he had simply slipped.
During the events of An Unearthly Child, the First Doctor meets the Eighth Doctor, who has travelled back in time to make telepathic contact with his past self in order to regain his memories. Unlike other Multi-Doctor Events, the First Doctor remember this encounter and so each of his next six incarnations will recognise the Eighth Doctor when he comes for their memories.
As a result of the Decayed Master's conceptual bomb erasing the TARDIS, the First Doctor is caught up in an alternate timeline which brings him into contact with all his other selves up to the Eighth Doctor.
