Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The Brigadier's confirmation of nationwide Auton attacks (Spearhead) sets the stage for the Doctor and Liz to be deployed to Wenley Moor, where a similar 'silent crisis' (power losses, neuroses) demands their intervention."

Why This Matters Across Episodes
The longer arc this connection carries
The systemic threat requiring UNIT's intervention transitions from overt alien invasion (Autons) to subtle, psychological warfare (Wenley Moor). The Doctor's expectation of action (from Spearhead) is fulfilled in Silurians, where he and Liz are immediately assigned tasks.
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.
