Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The Doctor’s insistence on proper lighting (phosphor lamp) in E7 foreshadows the urgency of power restoration in E8, where the battery’s failure is directly tied to the colony’s survival—both revolve around a single failing power source."

Why This Matters Across Episodes
The longer arc this connection carries
The technological dependency on limited power becomes a critical survival factor, escalating from a medical nuisance (poor lighting) to a life-or-death crisis (battery failure), binding the Doctor’s presence to the colony’s systemic collapse.
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.
