Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The Master's voice interception during the Doctor's communication attempt (POLICE SPACESHIP BRIDGE scene) directly causes the Doctor to be unable to provide authentic identification when communicating with Earth battle cruiser X two nine, leading to their incorrect accusation and arrest (Act 2). Both instances show how deception can create barriers to rational appeals."
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.
