Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The Doctor’s intervention to prevent a tactical nuclear strike against Eldrad in Part 3 (E7) leads directly to the Doctor, Sarah, and Eldrad being classified as ‘intruders’ by the Kastrian dome computer in Part 4 (E8). Eldrad’s survival and the Doctor’s refusal to destroy her catalyze the system’s hostile response."

Why This Matters Across Episodes
The longer arc this connection carries
This connection shows how the Doctor’s moral and strategic refusal to use force (escalated in E7) creates the very conditions that trap him and Eldrad in E8. The nuclear ultimatum of E7 indirectly causes the technological containment crisis of E8, deepening the Doctor’s entanglement with Eldrad’s survival.
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.
