Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The revelation (in Episode 37) that the TARDIS crew is trapped in revolutionary France directly causes the Doctor's desire to rescue Barbara and Susan (in Episode 38)."

Why This Matters Across Episodes
The longer arc this connection carries
Barbara and Susan's capture is the direct result of the events in Episode 37 (the Doctor's navigational error leading to revolutionary France and subsequent capture). The Doctor's decision to rescue them is a direct response to this, establishing continuity of purpose and consequence.
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.
