Theory:Doctor Who television discontinuity and plot holes/The Time Meddler


 * After finding a wrist watch Steven questions how this could be in the twelfth century when he has already been told they are in the eleventh century.
 * People often get confused with dates, also Steven is from the future so he likely doesn't know much about this era of history.


 * The Viking helmet the doctor finds at the beginning was never worn by any real Vikings.
 * In the Whoniverse this Helmet may have been worn by Vikings although not in the Real World. Also time is in flux.
 * Additionally, although there is no clear evidence that the Vikings commonly wore such helmets in reality, there is indeed evidence to suggest that similar helmets were at least used in ceremonial roles by the Vikings' ancestors. It's entirely plausible that some Vikings did wear horned helmets at times, albeit probably rarely.


 * Why do the Vikings not only trust the monk but obey him, shortly after they meet?
 * As this is known to be a ability of Time Lords, the Monk may have used some slight hypnosis on the Vikings, however in a more subtle way than the Master's "You Will Obey Me" routine.


 * The Doctor seems to forget at the end that he has left a space age rocket launcher in 1066, isn't that dangerous?
 * He probably did know and since he has a TARDIS he could easily leave with his companions then go back to 1066 for a little while to retrieve it later.
 * But he had no ability to control where the TARDIS landed at that time (and there was no indication that he would have that ability before meeting an untimely or timely end), so he couldn't easily go back and retrieve it later.
 * Although potentially dangerous, it most likely would have been largely disregarded and eventually rusted away. If he did indeed simply forget (which was not uncommon for him to do at this point in his life), he wouldn't have been able to do much about it if he remembered later.


 * The monk must be mad if he thinks that his Viking friends won't stop him destroying their fleet.
 * Bearing in mind he has no qualms about blowing an entire fleet of Vikings to perdition, it is safe to assume he will find it equally unproblematic to stab or shoot Sven and Ulf in their backs when they have outlived their usefulness.


 * Why doesn't the monks TARDIS have a lock? All other ones do (the Master's, the Rani's,ect).
 * Since the Monk is a renegade and a Time Meddler, he may have had his TARDIS slightly damaged and his lock lost in a run-in with the Time Lords.
 * Most cars come with locks, but some people are simply not in the habit of locking them. The Monk doesn't typically have to worry about random humans getting anywhere near his TARDIS without him being around, so why bother locking it?
