Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"Turlough and Peri’s sabotage of the numismaton gas supply in Episode 17 directly causes the Doctor’s urgent efforts to harness and stabilize the gas surge in Episode 18. The gas’s dangerous properties (triggered by the Master in Part 3) become the central focus of the Doctor’s attempts to fulfill the mission and stabilize the planet."

Why This Matters Across Episodes
The longer arc this connection carries
The gas surge is a direct consequence of Peri and Turlough’s sabotage in the bunker during Part 3. The Doctor’s escalated efforts to stabilize the gas in Part 4 are a direct response to the consequences of their actions, forming a causal chain across episodes.
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.
