Theory:Doctor Who television discontinuity and plot holes/The King's Demons


 * What happened to the desire Turlough expressed to return home at the end of Enlightenment?
 * He could have had a change of heart, the Doctor might not have been able to steer the TARDIS back to Trion during the right era, or there was an intervening, untelevised adventure where they did make it back, but Turlough decided to stay with the Doctor for the time being.''


 * Much of the history in this story doesn't make sense or is wrong:
 * The Master's iron maiden TARDIS has an anachronistic Elizabethan ruff.
 * Sloppy use of the chameleon circuit by the Master. The locals wouldn't have realized it as anachronistic, merely a little odd-looking of an iron maiden.
 * The Magna Carta's importance was fabricated in the 17th century: it achieved very little in the 13th century.
 * Taking into account the Master's ironic and smug smile when the Doctor proposes Magna Carta as the reason for today's scheme, it might well be that the Master was after something much more interesting and neglected to tell what it was.''
 * French was still the language of the court in the early 13th century, so why does only Sir Gilles speak it?
 * Logically, with the Doctor's translation circuit, everybody, even Sir Gilles, should be speaking a language that the Doctor and/or his companions can naturally understand. It is possible that we hear French because the Doctor can actually speak French without the assistance of the translation circuits.''
