Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The Doctor and Adric's failure to prevent the booby-trapped bomb arming in the cavern (due to a puzzle they couldn’t solve quickly enough) is referenced in Part 3 when the Doctor warns that stopping the freighter is the only chance to prevent Earth’s destruction."

Why This Matters Across Episodes
The longer arc this connection carries
This callback highlights the Doctor’s unresolved guilt and persistence. His earlier failure in the cavern haunts him on the bridge, driving him to double down on preventing the bomb’s delivery — a direct thematic and emotional continuity.
