Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The Doctor's deduction in Episode 7 that the Great Crystal's origin is tied to the Mara (as a 'terrifying purpose') directly causes his recognition of Lon's corruption by the Mara in Episode 8."

Why This Matters Across Episodes
The longer arc this connection carries
The Doctor's realization about the Crystal's Mara origin in Part 3 provides the intellectual framework for his immediate recognition of the Mara's mark on Lon in Part 4. This continuity of understanding stitches the episodes together around the theme of the Doctor's growing awareness of the Mara's influence.
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.
