The Pyramid at the End of the World (TV story)

 was the seventh episode of the tenth series of Doctor Who produced by BBC Wales.

The episode saw Bill make a deal with the Monks to help the Twelfth Doctor regain his eyesight, having been blind since TV: Oxygen, in which he was exposed to the vacuum of space.

Synopsis
At a war zone in Turmezistan where American, Chinese, and Russian armies are about to meet, a 5,000 year old pyramid stands. It's very strange, but one thing raises the suspicions of the United Nations: it just appeared overnight. The aliens inside claim that humans would cause the death of all life on Earth. Soon, the Twelfth Doctor, Bill and Nardole are facing an invasion the likes of which they have never seen before. Before they invade, the aliens need the permission of humanity.

Story notes

 * Filming on The Pyramid at the End of the World began on 28 November 2016, took a break for Christmas with Extremis, and then wrapped up on 17 January 2017.
 * This title has the longest word count for a Doctor Who episode, with eight words. By character, however, that would go to The Doctor, the Widow and the Wardrobe, with 32 characters over Pyramid's 28. The spin-off series Class trumps them both, with 42 characters in The Metaphysical Engine, or What Quill Did.
 * This episode featured a unique opening sequence in which it jumped back and forward between "Previously" and "Now".
 * A line of dialogue referring to terrorism was reportedly excised from the episode, out of respect for the victims of the, which occurred five days prior to broadcast.
 * When the Secretary General asks about the President, Bill says she doesn't know him, and says he is "orange". While never stated in the narrative, this is a reference to Donald Trump.
 * The Doomsday Clock is maintained by The Bulletin of the Atomic Scientists Science and Security Board. As the writing – and some of the filming – of the episode took place in 2016, the time shown in the beginning of the episode is three minutes to midnight. As of January 2017 – and so at the time of broadcast – however, the clock is set at two and a half minutes to midnight.
 * The United Nations is featured throughout in lieu of UNIT. This marks the first time the UN has played a major role in Doctor Who since the real-life organization requested UNIT's name be changed from United Nations Intelligence Taskforce in the mid-2000s (it became Unified Intelligence Taskforce).
