Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The Nova device's malfunction (later revealed to be a ruse by Tyssan and the prisoners) forces the Doctor and Romana into a high-stakes confrontation with the Movellans. This leads directly to the Doctor's later demonstration of the limitations of pure logic during the 'paper, scissors, stone' game, where the Movellans' rigid logic fails to break the impasse."
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.
