Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"Tarn's failed sealing of the gas lines in the control room (Ep 19) causes the collapse of the mine in Ep 20, as Ankh's removal of the fission grenade cap triggers the cave-in."

Why This Matters Across Episodes
The longer arc this connection carries
This connection carries the escalating conflict between Minyan authority figures — Tarn's incompetence and Ankh's ruthlessness — directly driving the physical danger the Doctor and his companions face. The earlier failure to contain the gas foreshadows the later structural collapse, reinforcing systemic instability.
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.
