Why These Connect
The narrative assertion
"Nyssa’s use of the scanner in the console room reveals Adric’s capture, which sets off the chain: Adric’s projection → warning → concealment → investigation → cosmic threat. Without this discovery, the crew would not have realized the TARDIS is being steered toward Event One."
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.
