Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The Doctor's failed attempt to convince Thous of Zaroff's madness and destructive plans (Episode 20) leads to Zaroff's increased confidence and brutality, culminating in his direct confrontation with Polly and Jamie (Episode 21)."

Why This Matters Across Episodes
The longer arc this connection carries
Thous' dismissal of the Doctor's warnings enables Zaroff's unchecked power, which directly causes the escalation of threats against the Doctor's team (e.g., Zaroff's brutal treatment of Polly). This demonstrates how institutional skepticism enables tyranny.
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.
