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?
 * The "Dragon", which contains the Dragonfire, was Kane's jailer & also the guardian of the treasure, as the Doctor explains at the end of Part 2. Its weapons could easily have killed Kane. Since the arrangement kept Kane confined for 3000 years, it worked reasonably well.


 * Why does Kane kill his mercenaries, having gone to the trouble of collecting them?


 * Pure speculation, but he may have been intending to send them en masse into the tunnels and against the dragon, hoping by sheer force of (expendable) numbers to locate the Dragonfire and kill his gaoler. The Doctor's arrival thus rendered them largely superfluous, though Kane was at least able to use them to "clear the decks" before reactivating his spaceship.


 * Alternatively, the sole purpose of the mercenaries may indeed have been to have exterminated the entire community of Iceworld when it no longer served Kane's purposes to play host to the traders and their customers. Whilst he is imprisoned there, they enable him to amass / extort resources and recruits with a view to freeing himself, but once he is free and the ship is in flight, they are just unwanted ballast...


 * 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.
 * As shown when he tried to recruit Ace, Kane relied on them being foolish enough to take his money -- as mercenaries -- in order to lure them into becoming (in effect) his slaves.


 * That works alright for the likes of Ace and Belasz, who were given that much choice. Not so well for Glitz's unfortunate former crewmates, who were given none. While a person may "sell" themselves as a mercenary, figuratively speaking, when someone else does the selling the term is a shocking misnomer (though the irony may still have been intended).


 * It almost certainly was intended, as the story contains a fairly obvious critique of capitalism. Kane, business magnate and gangster, sees everyone as commodities, and to deal with him at all is to deal with the devil ... Belasz and Kracauer may believe themselves to be free in comparison to the zombies in the freezer, but events will prove them completely wrong.


 * Why does Kracauer stand still and let Kane kill him?


 * Why does Stellar run around an ice planet in a dress?
 * There are 2 possibilities: First, although Stellar is described in this wiki as an Earth human, her species is never referred to on screen, so she may not be human & Iceworld may not seem cold to her species. (Kane looks human, too, but most of Iceworld is uncomfortably hot for him.) Second, even if she is human, individuals vary in their sensitivity to cold. She's also highly active most of the time, which would keep her warm.


 * At the end, why doesn't Stellar's mother behave as if there's been a massacre (which there has)?
 * Stellar's mother had been searching for Stellar & was not present when the massacre occurred. By the end, when she finally finds Stellar, she has still not encountered anything to indicate that there has been a massacre -- no heaps of corpses, only an absence of the usual throng. She doesn't behave as if there's been a massacre because she doesn't know there has been.


 * How is it possible for the ice cream parlour's milkshakes to even exist? Wouldn't alcohol be more realistic, as milk would be frozen solid?
 * Since humans and humanoids are living there, the temperature cannot always be below freezing. The places where people live are covered and heated.  Much like a large shopping mall.  The ice cream parlour itself is warm inside, and they use a more or less standard milk shake machine.


 * Considering Ace is now millions of years in the future from her own time, how does Glitz intend to get her home? Before she leaves Mel makes the obvious point that the Doctor would be the better one to bring Ace home yet neither he, Ace or Glitz seem to acknowledge this.
