Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The Doctor’s realization in Episode 21 that Zaroff’s absence is critical to halting the reactor directly leads to the decision in Episode 22 to flood the lower levels of Atlantis, causing tunnel instability that threatens Jamie and Polly."

Why This Matters Across Episodes
The longer arc this connection carries
The Doctor’s strategic deduction in Episode 21 about Zaroff’s necessity for the reactor’s activation logically results in the flood plan in Episode 22, which destabilizes the tunnels. This creates a direct cause-and-effect chain where Jamie and Polly’s peril in Episode 22 is a consequence of the Doctor’s plan to stop Zaroff.
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.
