Theory:Doctor Who television discontinuity and plot holes/Dragonfire


 * It's not exactly an "error", in the sense that the production team intended it, but the literal cliffhanger at the end of part one is a big, ol' cheat. At the end of part one, the Doctor looks down an almost bottomless cliff of ice. But by the start of the next, the camera shifts to reveal that there's a handy little ledge, onto which Glitz is able to pull the Doctor.
 * It's unclear why the Doctor, went out on the ledge.
 * This occurred because an important scene was removed which would have justified it.


 * Why hide the Dragonfire on the part of the planet that Kane can get to?
 * Why does Kane kill his mercenaries, having gone to the trouble of collecting them?
