Theory:Doctor Who television discontinuity and plot holes/World War Three


 * What happened to the Slitheen Craft after the end of this episode?
 * Possibly taken to study by UNIT or Torchwood.
 * On the Doctor Who Micro-Universe Slitheen Cruiser packaging it states that Torchwood took possession of the ship.


 * How does Harriet Jones know that the Slitheen's farts don't smell like a fart if she hasn't even been in the presence of one while it farted.
 * Harriet Jones witnessed the death of General Asquith. The Slitheen farted before killing him and, although she was hiding in the cupboard, she most probably smelled them then.


 * How does Rose know that Slitheen farts smell like bad breath if a Slitheen hasn't farted near her.
 * The smell can travel and linger for a while.


 * How is it that the Doctor, Harriet and Rose can all stay in that small cupboard during the missile attack and come out of it pretty much unscathed? No slight concussion, nothing sprained or broken. The three somehow don't show any signs of pain after the strike.


 * How is it one second the Slitheen disguised as the acting prime minister is giving a speech outside downing street, then the next second he is standing outside where the Doctor, Harriet and Rose are?


 * The Doctor says that Harriet Jones is elected for three successive terms in 2006, presumably winning the first in that same year (The Prime Minister has been skinned). As such, she would still be Prime Minister in 2009, during the events of Torchwood Children of Earth when Brian Green was Prime Minister? Or did the 'Year that never was'(When The Master was Prime Minister) mess with the timelines?
 * An alternative timeline perhaps?
 * The events of The Christmas Invasion (TV story) caused Harriet Jones downfall. This was the Doctor's intervention that rewrote the timeline. As an additional point, "terms" in the UK while they are limited to five years, general elections can be called at any time by the Prime Minister. (Until the Fixed Terms Parliament Act 2011) In theory, Harriet Jones could have called three general elections in the space of one or two years and still would have served three successive terms, just not full five year terms.
