Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The Doctor's acceptance of the Brigadier's call to investigate the oil rig disasters (Ep 1) directly leads to his arrival at the Fox Inn and Harry's later vulnerability to abduction (Ep 2)."

Why This Matters Across Episodes
The longer arc this connection carries
The Doctor's initial intervention in Ep 1 forces his engagement with UNIT and the Brigadier, which places his companions (especially Harry) in proximity to the Zygon threat in Ep 2. The Doctor's own admission in Ep 1—that 'to be dependent upon a mineral slime just doesn't make sense'—underlines his proactive response to crises, setting up his later inability to prevent Harry's capture.
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.
