Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The explosive plan authorized by the Colonel in Part 3 to seal off Goodge Street is directly undermined in Part 4 when the Goodge Street Fortress entrance is found open and the lab ransacked—indicating the Intelligence anticipated or exploited the plan."

Why This Matters Across Episodes
The longer arc this connection carries
The Doctor’s detonation plan was intended to protect the base, but the Yeti break-in in Part 4 reveals the plan failed—either because the Yeti used the explosion’s distraction or because the Intelligence was two steps ahead. This creates a causal link between human strategy (Part 3) and its tactical failure (Part 4).
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.
