Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The Doctor's follow-up on Buller's body (establishing him as a cabbie) in Episode 21 causes the investigation to focus on cab drivers and their missing family members, leading directly to Quick's report about Joseph Buller's desperate search at the Palace Theatre in Episode 22."

Why This Matters Across Episodes
The longer arc this connection carries
This causal link drives the personal connection element of the mystery. Buller's status as a cabbie becomes crucial intel linking the personal tragedies (wife's disappearance) to the larger supernatural threat (the theatre's role in disappearances).
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.
