Continuity

 * The Doctor and the Brigadier are still not back on good terms after the bombing of the Silurian base on Wenley Moor (TV: Doctor Who and the Silurians)
 * Liz comments that her dissatisfaction with her role in UNIT arose because she felt all she had to do was tell the Doctor he was brilliant and pass him his test tubes. She later told the Brigadier this, because he used this to convince the Doctor to accept Jo Grant as his new assistant in Terror of the Autons.
 * The Sergeant who dies in the story is stated to be Benton's immediate predecessor, thus setting this story before The Ambassadors of Death. Liz comments wryly upon the oddly British practice employed by UNIT of "hot sweet tea" salving all wounds.
 * The Doctor is said to still be deeply offended at being imprisoned on Earth. (TV: Spearhead from Space)
 * The Time Lord in a bowler hat appears in the TARDIS. He would later appear in TV: Terror of the Autons to warn the Doctor of the Master's arrival on Earth.
