Narrative Connection
How these two moments in the story relate

Why This Matters Across Episodes
The longer arc this connection carries
This is a direct causal link: the Doctor’s sudden removal with his companions enables the isolation of Susan and Ian in the Aztec tomb in the next episode. The cross-episode tension—'Why did the Doctor leave us here?'—drives tension in Episode 27 and forces Susan to act independently.
