Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The Doctor and Harry's infiltration of the cave containing Davros's prototypes in Episode 12 enables their later infiltration of Thal corridors in Episode 13, using similar stealth tactics learned in that harsh environment."

Why This Matters Across Episodes
The longer arc this connection carries
The Doctor and Harry's skill in navigating enclosed, dangerous spaces (ventilation ducts to caves in Episode 12) is applied directly in Episode 13 when they use cramped service tunnels to reach the Thal corridors undetected. This maintains the Doctor's role as an infiltrator whose actions cascade across episodes.
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.
