Story notes

 * On The Fan Show, Jamie Mathieson jokes that the Twelfth Doctor's hair is "chalky blonde", rather than grey.
 * On The Fan Show, Jamie Mathieson worried that this episode would turn out "too political".
 * On The Fan Show, Jamie Mathieson said that an ongoing joke on set was calling Peter Caulfield "Blue Peter", due to his character being blue. This was a reference to Blue Peter.

 * The Doctor makes a speech about space being "the final frontier". A similar speech is made in Star Trek.
