Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The Doctor's exposure of the Wirrn's parasitic lifecycle (Episode 6) justifies his later reversal of the transmats (Episode 7) as a desperate gamble to access the Wirrn's vulnerability to electricity."

Why This Matters Across Episodes
The longer arc this connection carries
The earlier episode's biological revelation provides the scientific basis for the later act's technological solution. Without the Doctor's understanding of the Wirrn's electrical weakness (via the parasite's biology), his reversed-transmat scheme in Episode 7 would lack logical foundation. This thread ties the two episodes' problem-solving arcs together.
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.
