Why These Connect
The narrative assertion
"Barnham's sacrifice to disrupt the Keller Machine enables the Master to escape (beat_53ab228704531b53). As a result, the Doctor realizes during the following debrief (beat_44fd924a1ae434c7) that he lost the dematerialization circuit during the scuffle, compounding the consequences of that sacrifice."
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.
