Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The Doctor's observation in Part 1 that the oxygen supply is active despite the breathable atmosphere foreshadows the Part 2 discovery of the Daleks' reliance on Spiridon-derived energy waves for invisibility. Both moments involve the Doctor identifying an unsustainable or misapplied energy system."

Why This Matters Across Episodes
The longer arc this connection carries
The Doctor's analytical mindset, applied first to environmental sabotage and later to Dalek technology, demonstrates his consistent approach to problem-solving. The pattern of identifying hidden flaws in systems (environmental or technological) becomes a key thread in his arc.
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.
