Why These Connect
The narrative assertion
"The Doctor's recounting of the Time Lord legend about giant vampires in the cell (beat_9abeb17dbf23bfc3) stimulates Romana's memory and leads directly to their plan to access the Record of Rassilon in the TARDIS (beat_4c50be47ad59f1c6), as they seek to uncover the vampires' weaknesses."
About Causal Connections
A directly causes B. The first event sets forces in motion that produce the second. These are the load-bearing connections of plot—remove one and the story structure collapses.
