Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"Grendel's order to create a perfect android duplicate of Romana despite the risks (beat_cad84c7e4d189d9e) is enabled by the Doctor's earlier revelation that Romana's non-Taran origins complicate duplication (implied in beat_c9d35e28a573d67b, though not explicitly stated, the tension between Grendel's ambition and the complexity of the task is emphasized)."
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.
