Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The Doctor's early revelation of a coordinate override in his TARDIS (Act 1) foreshadows his deeper strategic understanding and counters the Master's plan, ultimately leading to the Doctor's ability to outmaneuver him. This same strategic thinking drives Hayter's scientific pursuit of the Xeraphin, culminating in his absorption—a tragic consequence of unchecked curiosity."
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.
