Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The Doctor and Ace descending a hidden tunnel in Episode 2 becomes the revelation that people (including the Doctor) are trapped underground in Episode 3, completing the causal loop of excavation and entrapment."

Why This Matters Across Episodes
The longer arc this connection carries
The tunnel's dual role— as a plot device that reveals Morgaine's presence and then traps the Doctor—drives the episodic arc from discovery to rescue/return, merging cause and consequence across episodes.
