Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The Black Dalek's dismissal of Chen's negotiation in Episode 15 ('Coronas of the Sun') directly causes the Daleks' urgent need for the taranium core, which then leads to the confirmation of the Time Destructor's operational status in Episode 17 ('Volcano'). The taranium's importance is reiterated in both events."

Why This Matters Across Episodes
The longer arc this connection carries
The taranium core's significance is established as a critical MacGuffin in Episode 15, where the Daleks demand its return. The Black Dalek's dismissal of Chen's negotiation implies that the Daleks will take direct action (extermination) if they secure the taranium, which is the same taranium fitted into the Time Destructor in Episode 17. This creates a direct causal link where the earlier negotiation's failure drives the Daleks' later haste in preparing their temporal weapon.
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.
