Why These Connect
The narrative assertion
"The Doctor’s instruction to K9 to monitor surroundings introduces a motif of surveillance and grim efficiency. This early setup is mirrored later when K9’s systems degrade under duress—both instances reflect the Doctor’s reliance on his companion’s function amid peril."
