Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The encirclement and attempted trap of Turlough and Bulic by Sea Devil forces (Ep 3) directly leads to the Silurian use of hexachromite gas in Ep 4, as the Doctor retrofits human chemical weapons to counter the disciplined ambush tactics observed earlier."

Why This Matters Across Episodes
The longer arc this connection carries
While the exact individuals may differ, the disciplined Sea Devil enclosure technique (used to trap Turlough/Bulic) foreshadows the more generalized discipline in ambush tactics seen in Ep 4’s chemical store ambush. This enables the Doctor’s eventual use of hexachromite as a response to disciplined Silurian tactics.
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.
