 * In his first scene in the story, Jon Pertwee says "I couldn't open it even if I wanted to" twice in rapid succession.
 * He's emphasizing the point.


 * In Episode 3, Stubbs and Cotton wonder aloud if the Marshal is on to them. The camera moves to follow them, revealing a third guard standing less than a meter away, who is presumably deaf to their confession of treason.
 * He wasn't paying attention, or simply didn't hear them, despite their relative proximity.


 * While the thoroughly anti-imperialist Doctor of this story seems consistent with most portrayals from "The Sensorites" to "The Happiness Patrol" and beyond, he contrasts rather glaringly with his previous season's depiction in "Colony in Space", where he was avidly urging the future human characters to leave their polluted and over-populated Earth and settle on Uxarieus, though the natives, by and large, were lukewarm at best about the incursion.
 * Why do Sondergaard and the Doctor need to remain in the caves to work on the translation? They could just as easily do it in Varan's village.
 * They prefer to work without interruption.
