Theory:Doctor Who television discontinuity and plot holes/Dragonfire

You are exploring the Discontinuity Index, a place where any details or rumours about unreleased stories are forbidden.
Please discuss only those whole stories which have already been released, and obey our spoiler policy.

This page is for discussing the ways in which Dragonfire doesn't fit well with other DWU narratives. You can also talk about the plot holes that render its own, internal narrative confusing.

Remember, this is a forum, so civil discussion is encouraged. However, please do not sign your posts. Also, keep all posts about the same continuity error under the same bullet point. You can add a new point by typing:

* This is point one.
::This is a counter-argument to point one.
:::This is a counter-argument to the counter-argument above
* This is point two.
::Explanation of point two.
::Further discussion and query of point two.

... and so on. 

• 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?
• In a bizarre (and oft-repeated) piece of scripting, the word "mercenaries" is often used completely misleadingly, as Kane's frozen zombie army are most definitely slaves.
• Why does Kracauer stand still and let Kane kill him?
