Why These Connect
The narrative assertion
"Turlough's philosophical inquiry about killing (beat_09917836f8ca2317) leads to his eventual adherence to the sentient crystal's demand for obedience and his plan to kill the Doctor (beat_7a9e7601325bee24), revealing the crystal's influence over his moral compass and mission."
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.
