Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The Shadow's psychological manipulation of Astra in Part 4 directly leads to his triumphant yet ultimately foiled attempt to seize the Key to Time in Part 6. Astra's deception of the Doctor and Merak's infiltration are both products of the Shadow's earlier scheme."

Why This Matters Across Episodes
The longer arc this connection carries
The Shadow's binding of Astra to lure the Doctor (Part 4) sets up the entire sequence of events in Part 6, including the Doctor's capture and the revelation of the Key's corruptibility. This causal chain demonstrates the Master's unchanging tactic of using others as pawns, escalating from psychological control to physical domination.
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.
