Why These Connect
The narrative assertion
"Romana’s fall down the metal shaft occurs after she is pursued by a crewman, which is directly caused by Romana being separated from the TARDIS (due to explosions blocking her path), placing her in extreme peril and necessitating her call for K9’s assistance."
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.
