Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"Garron's discovery of the hidden microphone (Part 3), which allows the Doctor to warn Unstoffe, directly leads to the Doctor splitting forces in Part 4, sending Romana and Garron toward the city exit while he tracks Graff's lieutenant."

Why This Matters Across Episodes
The longer arc this connection carries
The successful (though concealed) communication link in Part 3 enables the Doctor's strategic decisions in Part 4, such as dividing the group to cover more ground. This connection underscores the importance of Garron's initial vulnerability (his crushed communicator) and the Doctor's improvisation.
About Causal Connections
A directly causes B. The first event sets forces in motion that produce the second. These are the load-bearing connections of plot--remove one and the story structure collapses.
