Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The Brigadier's urgent report of the Ben Nevis disaster in Episode 1 directly causes the escalation of the crisis in Episode 2, where the Zygons' coordinated attack (nerve gas, Skarasen deployment) is revealed as a response to human investigative actions."

Why This Matters Across Episodes
The longer arc this connection carries
The transition from the oil rig explosions in Episode 1 to the Zygon nerve gas attack in Episode 2 is precipitated by the Brigadier's actions in mobilizing the Doctor and UNIT to investigate, which the Zygons perceive as a direct threat to their invasion plans.
