Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The Doctor and Codal's discussion about the Daleks' invisibility derived from Spiridon study (in the jungle) directly motivates their later plan to jam the Daleks' guidance system using a motor converted into a transmitter (in the cell). The invisibility tech's reliance on power and frequency manipulation becomes the core mechanism for their escape strategy."
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.
