Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The reveal of the Hydrax lineage and the Lords' vampiric origins (Episode 13) directly callbacks to the Doctor's later search for the vampires' weakness in the Record of Rassilon (Episode 15)."

Why This Matters Across Episodes
The longer arc this connection carries
The Hydrax connection establishes the vampires' cosmic-scale threat, which the Doctor later contextualizes through Rassilon's archives. This creates a direct throughline from the discovery of the Lords' true nature to the solution for their destruction.
