Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The Doctor and Romana's exposure of the Swampies' Kroll sacrifice as a ruse (beat_3c624ba06d74863b) directly leads to their investigation of the tribe's ancient texts in the Kroll Pit (beat_7969b9c76f83a49a), where they uncover Kroll's true nature and past manifestations. This establishes the foundation for their later deduction that the refinery is disturbing the real Kroll."
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.
