Why These Connect
The narrative assertion
"The Movellans disclose their plan to detonate the Nova device to destroy Davros after the Doctor's use, setting up the Nova device as a weapon. Davros's premature triggering of the suicide Daleks' explosives (via the Doctor's manipulation) ensures the Nova device never detonates, directly countering the Movellans' plan."
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.
