How these two moments in the story relate
Why These Connect
The narrative assertion
"Harker's report of the Brigadier's arrest (Episode 13) creates a power vacuum that the Doctor exploits by demanding command over the Master in Episode 14."

Why This Matters Across Episodes
The longer arc this connection carries
While the Doctor's plan to use the Master involves multiple factors, the chaos resulting from the Brigadier's arrest (and Jo's disappearance during that chaos) weakens traditional authority figures, allowing the Doctor to take unilateral action in Episode 14.
