Theory:Doctor Who television discontinuity and plot holes/Planet of Fire


 * The Doctor asks Amyand and Sorasta about Logar, despite having never heard the name before.
 * This is incorrect. Logar is mentioned, albeit briefly, in the section of the scene directly proceeding the Doctor asking about him.


 * Peri can override the Master's control of Kamelion, but the Doctor can't.
 * The Master's mental powers have been greatly diminished as a result of his accident. It is also suggested that the numismaton residue shields Kamelion from the Doctor's brainwaves.


 * Why is there a hollow turtle shell on the wall of the Master's miniaturised control room?
 * Why not? The Doctor and the Master have both collected and stored in their TARDISes various "souvenirs" from their travels.


 * Where did the Master get the miniaturised equipment for his control room.
 * He either built it (he's quite good at that sort of thing), or perhaps reduced the size of an pre-existing control room within his TARDIS (possibly using the dimensional stabiliser).


 * If the Master's gun is a Tissue Compression Eliminator, why does it compress Kamelion and the radiation suits?
 * This was the very advancement the Master was trying to achieve when he had his accident - i.e. a TCE that works on inanimate matter as well. 
 * Peri seems to be able to out-run its blast in episode three.
 * The TCE was only ever meant as a short-range weapon.


 * Why doesn't the TCE kill the Master, as it does his victims?
 * Because what happened was the result with him experimenting with the power of the TCE, not merely shooting himself with it.


 * We see the Master get all burned up in regular fire at the end of the adventure. Yet there he is again, right as rain in DW: The Mark of the Rani.  So how did he survive the complete destruction of his body?
