Synopsis
The security of the entire world is at stake, so head of MI6, C, enlists Thirteenth Doctor and her team to investigate former agent spy Daniel Barton to see if he's been turned against them. Meanwhile an alien threat that can pass through walls, even TARDISes, known as the Kasaavin is wiping out spy organisations all over the planet. Can former MI6-leader "O" help them, or is he not who he claims to be?

Story notes

 * This was the first multi-part television story to be given one overarching title since 2009-10's The End of Time, and only the second such story in the BBC Wales era.
 * Incidentally, both stories aired in part on New Year's Day, and both featured the Master.
 * Part one of Spyfall was, in fact, broadcast on the 10th anniversary of 1 January 2010's The End of Time: Part Two. Each aired on the first day of their respective decade, according to one outlook on the bounds of such a measurement, which this wiki follows.
 * The first part of this story was dedicated to the memory of the "Masterful" Terrance Dicks.
 * Some scenes in this story were filmed in South Africa.
 * This story's title is a play on the 2012 James Bond film Skyfall.
 * According to one news source, the story also pays homage to Casino Royale, the first novel in the Bond series, centered on gambling and aristocracy which has been adapted twice in 1967 and 2006.
 * The concept of MI6 members being known by a single letter, namely "C" and "O", may also be in reference to a similar feature ("M" and "Q") seen throughout the James Bond franchise, introduced in the original novels by Ian Fleming.
 * This is the first episode since Twice Upon a Time to include a "cold opening".

Continuity

 * A doctor offers Graham his condolences regarding Grace O'Brien's death. (TV: The Woman Who Fell to Earth)
 * It has been four years since Graham's operation. Previously, in September 2018, he told the Doctor that he had been in remission for cancer for the past three years. (TV: The Woman Who Fell to Earth)
 * The Doctor's life is once again threatened by a SatNav device controlled by a power intent on killing target passengers. In her tenth incarnation, the Doctor narrowly escaped from an ATMOS-controlled UNIT vehicle which was about to plunge him and Jenkins to their "final destination". (TV: The Sontaran Stratagem)
 * When C dismisses the possibility of alien life, the Doctor tells him to ask the GCHQ, referring to the Dalek attack of New Year's Day 2019. (TV: Resolution)
 * The Doctor notes that both UNIT (TV: Resolution, PROSE: Lucy Wilson and the Bledoe Cadets) and Torchwood (TV: Doomsday, Children of Earth: Day One, AUDIO: Thoughts and Prayers) are "gone".
 * The Master, while still under the guise of O, refers to the Doctor as having once been a man. (TV: An Unearthly Child, Twice Upon a Time, et al.) Graham recalls the Doctor having made this claim, which he believed to be a joke. (TV: The Woman Who Fell to Earth)
 * Graham is mistaken as the Doctor, (PROSE: The Good Doctor) and the Doctor herself is immediately dismissed, in favour of Graham, on account of her gender. (TV: The Witchfinders)
 * The Doctor refers to her regeneration to female form as an "upgrade", much as once did. (TV: The Witch's Familiar)
 * The Master has used his Tissue Compression Eliminator to shrink the original O. (TV: Terror of the Autons et al.)
