Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"Bellal's explanation of how the city drains electrical energy via a beacon directly motivates the Doctor's later plan to restore power to the TARDIS and assist the Earth mission ship—central objectives established in the aftermath of the tunnel escape. The city's energy-draining nature becomes a tangible threat linked to the Doctor's strategic goals."
