Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The Doctor's exposure of the Cybermen's weakness to gold directly causes Ringway's near-discovery of Adric's gold star badge (putting them in immediate danger). Ringway's near-discovery places pressure on the Doctor to hide Adric's badge, which indirectly constrains the Doctor's ability to reveal other Cyber weaknesses or plans — such as the immediate breach of the bridge by Cybermen. The near-discovery causes the Cyber to be aware of the Doctor's knowledge and plans leading to the Cyber's immediate escalation tactics against the bridge. The Doctor's plan for defense is revealed while the Doctor is aware of the Cyber awareness tactics. The chain of events triggers the Cyber's immediate escalation tactics."
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.
