Theory:Doctor Who television discontinuity and plot holes/Frontier in Space


 * If the Master's device makes one see one's greatest fear, why does Jo see the ship change shape in episode one?
 * The implication is that she is seeing the effect of the device being turned on, but it's still an error; Jo wouldn't be afraid of a Draconian ship any more than any other kind of spaceship.


 * Big strings hold up the Doctor up for his spacewalk in episode six.
 * This is probably due to the fact that if a course correction was made like in episode four, then the Doctor would not drift away.


 * As the space walking Doctor opens the airlock in episode four there is a technician visible inside it.


 * If the Master's devise makes Jo see people as Drashigs at first, then why wouldn't she see them every time she hears that sound?
 * Different fears are foremost in her mind at different moments.
