Narrative Connection
How these two moments in the story relate
Why These Connect

Why This Matters Across Episodes
The longer arc this connection carries
This causal link demonstrates how the Doctor's established expertise (Part 2) is weaponized in Part 3 to build trust with Liz, creating a moment of betrayal when his deception is revealed. It also shows Liz's growing trust in the Doctor despite her initial skepticism.
