Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The Master berating an Ogron in the Draconian palace for leaving one of their own behind, realizing the hypnosound truth will eventually be discovered when it wears off (OGRON SPACESHIP BRIDGE scene), directly causes the Doctor's later actions to be anticipated and countered as the Master decides the Doctor and his evidence must be prevented from reaching Earth (Act 2)."
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.
