Why These Connect
The narrative assertion
"The Doctor's observation of the Nucleus's transformation (beat_ed3c2fd5f919c325) reveals the alien entity's control over Professor Marius, leading directly to the Nucleus ordering Marius to recapture the Doctor for transport to Titan (beat_bbd399dd5723d37d). This establishes the Nucleus's strategic planning and influence over its hosts."
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.
