NOTES
The Zygon Invasion was the seventh episode of the ninth series of Doctor Who produced by BBC Wales.
A portrait of the First Doctor hangs in the UNIT safe house in South London.
The Doctor starts calling himself “Doctor Disco” and “Doctor Funkenstein.”
The Doctor plays Amazing Grace on his guitar.
The Doctor refers to Jemima and Claudette as “Monster High” and “Cinderella.”
When the Twelfth Doctor introduces himself as “The President of Earth, ” a UNIT official answers with “Yes, we know who you are, ” a reference to Harriet Jones.
Clara’s voicemail greeting says she’s eitheron the tube or in outer space.
Clara says she heard about the series Truth or Consequences on the game Trivial Pursuit.
A poster in Osgood’s office says that the White House has appointed an alien ambassador.
The Doctor gave the Osgoods an Osgood Box that was only to be used in the Nightmare Scenario and if Operation Double was broken.
Osgood has the TARDIS’s phone number. She uses a question mark as its contact photo.
The Radio Times programme listing was accompanied by a small colour shot of Osgood and the Twelfth Doctor, with the accompanying caption “Doctor Who/8.15 p.m. Osgood is snatched by aliens, prompting a round-the-world rescue mission”.
Given that the “Clara” in most of this episode is a Zygon duplicate, this is the second consecutive episode in which the real Clara is only onscreen up until the scene in Sandeep’s flat, and in the concluding seconds of the episode.
