Theory:Doctor Who television discontinuity and plot holes/Logopolis

• When Nyssa objects to the Doctor collaborating with the Master, the Doctor states "I've never chosen my own company." but in the very first Doctor Who (DW: An Unearthly Child ), he CHOSE to kidnap Barbara and Ian. Susan pleaded with him to let them go.

• This story features the Doctor's TARDIS materialising around the Master's TARDIS and creating a gravity bubble and the recursive phenomena of infinite TARDIS'es nesting within each other. Two TARDIS's materialised "inside" each other in DW: The Time Monster, but did not happen when the TARDIS materialised inside Professor Chronotis's rooms (actually his TARDIS in disguise) in the untelevised DW: Shada.

Chronotis's room was not a complete TARDIS; it was not dimensionally transcendant.

• Why does the policeman take the doll-like corpses so seriously?

Because he recognizes one of them as being the first constable seen in the story.

• Surely the Doctor's plan of flooding the TARDIS to flush-out the Master is absurd nonsense.

The Doctor was feeling very fatalistic at this point. It is doubtful there is a normal procedure of what to do when your arch-nemesis creates a gravity bubble within your TARDIS.

• Tegan appears amazingly reconciled to the extraordinary events happening around her. In particular she does not appear to comment on the size of the TARDIS. She witnesses the regeneration of the Doctor without any evident wonderment and without questioning what is happening.

Different people react to extraordinary events in different ways.

• The only indication that the Watcher is the Doctor's future self is Nyssa saying, 'so it was the Doctor all along'. But how does she know?

As he is merging with the Doctor laying on the ground, she works out that it must be the Doctor.

• It is never really explained how/why the Watcher has come into existence for this regeneration and not previous or future ones.

It's a process that is not always necessary. It's been rather clearly shown that the Doctor does not have the smoothest time with regeneration. Sometimes he needs a little help, even if from a future part of himself.

• The lock on the Master's TARDIS changes place in part 1.

A functioning chameleon circuit is more than capable of changing the location of the lock.

• In Part 4, the Master's TARDIS materialises just before the worker leaves the room, Surely the worker would have heard it?.

• When Adric and Nyssa are "outside time and space", how can they possibly see things that change with the passing of time - i.e. the growing entropy field?

The TARDIS scanner could show them the areas of Space-Time in which they were interested, much as the Time-Space Visualiser could in DW: The Space Museum and The Chase

• Why does the Doctor have a flashback of the Decaying Master when he's just met the new one?
• Why is there a litter bin next to the 'Take Your Litter Home' sign in episode one?
