Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"Skagra's extraction of the Worshipful and Ancient Law of Gallifrey from Chronotis (in Shada Part 2) directly enables his meddling with time manipulation and pursuit of Shada (revealed in Shada Part 4), as the book is explicitly connected to the prison planet."

Why This Matters Across Episodes
The longer arc this connection carries
This link carries the central conflict of the story arc: the theft of the ancient Gallifreyan artifact enables Skagra's villainous actions. Chronotis's inability to protect the book in Part 2 leads to its misuse in Part 4, escalating the threat.
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.
