Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The Doctor's deduction in Act 1 that Meglos intends to use the Dodecahedron with the Screens of Zolfa-Thura directly motivates his later infiltration and sabotage of Meglos's control complex in the laboratory. The Doctor's understanding of the Dodecahedron's operational framework (Screens + control complex) sets up his later actions in Meglos's lab."
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.
