Theory:Doctor Who television discontinuity and plot holes/The Pyramid at the End of the World


 * Bill says the current president (of the United States) is "orange". Even if we were to go under the assumption that the president at this point in the DWU was a different "orange" man and not Donald Trump, this goes against what was depicted in the simulation in Extremis where the unnamed president appears to be a pale-skinned man.
 * It was a simulation. We can't be sure it is 100% accurate, more like 98,99. Regardless, whose to say the president isn't orange in another sense; it was never clarified she meant skin.
 * Also, real-life politics do not align with those in the Whoniverse. In the Whoniverse it is implied that Barack Obama succeeded one Arthur Coleman Winters as president, and that in the second half of the 2000s the prime minister of the UK was Harriet Jones.


 * Although they are referenced, the otherwise total absence of UNIT is difficult to reconcile given its mandate is to investigate things such as a pyramid appearing out of nowhere. Certainly once the Doctor realized they were looking for a specific event he should have called in the entire might of UNIT. In addition, the previous two appearances of Boat One suggest the aircraft itself is operated by UNIT.
