Why These Connect
The narrative assertion
"The power cut in the space liner directly causes the transition from 'stage one' to 'stage two sterilisation' (gas). This escalates the immediate danger from radiation or contamination to active, lethal gas, forcing the companions to flee and marking a turning point in the story's urgency."
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.
