Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"Clare's scientific analysis of the book's anomalous properties (no atomic structure, carbon dating of -20,000 years) provides the empirical foundation that allows the Doctor to later devise a pursuit strategy to Shada. The book's temporal instability, revealed in Part 2, is directly tied to Skagra's scheme of releasing Salyavin from Shada's prison."

Why This Matters Across Episodes
The longer arc this connection carries
This connection carries the core conflict of Clare's inability to reconcile scientific understanding with temporal anomalies. Her rigorous testing in Episode 22 provides the scientific 'proof' that convinces the Doctor of the book's gravity-shifting properties, which he then uses to track Skagra's movements across the Time Vortex in Episode 25. The unresolved tension in Clare's character—her scientific mind grappling with the impossible—is thus directly tied to the existential stakes of Skagra's 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.
