Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The Doctor's urgent instruction to Sarah to retrieve a machine from the TARDIS (beat_7482fa118e0807f0) directly compels Sarah to undertake the perilous journey to the TARDIS and retrieve the satchel (beat_e8b9684e2aded214). This causal chain bridges the Doctor's life-or-death condition with Sarah's immediate peril and sets the stage for her capture by Lupton."
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.
