Theory:Doctor Who television discontinuity and plot holes/The Krotons


 * Beta is magically transported from place to place.
 * Time occurred between scenes.


 * One of the characters states something along the lines of "and the Earth and soil was tainted". How would they know of the planet Earth, and how the name of it is also connected to the ground?
 * It is simply an affect of the translation, the same reason goes for why several aliens have refered to events as "unearthly"


 * Let's rewrite the part in quotes: "and the earth and soil was tainted". Using a lower-case "e", there's nothing peculiar about the statement. Obviously, the character wasn't referring to the proper noun "Earth", but instead the common noun "earth" which happens to be the same word.
