Theory:Doctor Who television discontinuity and plot holes/Enlightenment


 * There are still a few fragments of the red jewel left after the Doctor picks them up. Why not pick-up the rug the jewel fragments are on rather than try to transfer them into the handkerchief anyway?
 * He was pushed for time, and picking up an entire rug isn't the quickest way to do anything.


 * Why don't Wrack and her first mate vanish the instant they are pushed overboard the Buccaneer, towards the end of episode four, like the Eternals who are forced to walk the plank earlier in the story do?
 * Black Guardian protection?


 * Solar winds do not travel fast enough to propel the ships at the speeds they are obviously capable of, given the relatively short amount of time it takes them to travel between the planets of the solar system.
 * The solar winds do not actually propel the ship. They are merely the source of energy which is converted within the drive sections of each ship, into another form of faster motive power.


 * Why would the Black &amp; White Guardians be holding a race for the Eternals in the first place? They are the Guardians of universal order and chaos, not cosmic entertainment providers.
 * The Eternals potential for creating problems for both of them, in their quest for entertaining distrations is formidable. Organizing the occasional mass event like this just makes the Guardians existences easier in the long-run.
 * To judge from the whimsical nature of their manifestations (such as the southern gent in "The Ribos Operation", to say nothing of bird-themed headgear ...) even the Guardians occasionally feel the need to inject some amusement into their appointed roles.
