Why These Connect
The narrative assertion
"Tegan’s diversion in the Great Hall allows the Doctor to slip away unnoticed. This escape directly enables him to enter the King’s Chamber undetected, confront the Master, and execute the plan to escape with Kamelion and Tegan in the TARDIS—driving the climax of Act 3."
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.
