Theory:Doctor Who television discontinuity and plot holes

This is the main page on this wiki for the discussion of discontinuity in Doctor Who television stories. Feel free to use this list to create pages that discuss in detail all the continuity errors that you've found — or think you've found — in your favourite episodes of Doctor Who.

The notion of removing discontinuity sections from mainspace article pages was deemed approved by community consensus at Forum:Discontinuity revisited. Therefore, please do not attempt to add discussion of narrative discontinuity on the episode pages themselves.

Tech notes

 * The slash (/) in front of episode names is necessary in order to create a link back to this page, and to prevent a link to the main article itself.  The slash at the end merely performs a slash trick, thereby removing the slash at the front from displaying.
 * All titles must be italicised, per T:ITAL
 * When adding new episodes to this list, it is critically important that they be placed into Category:DW TV discontinuity.
