Why These Connect
The narrative assertion
"The Doctor's decision to leave Nyssa and Adric behind (beat_057732c46c84b9fb) directly follows from his earlier instruction that they should remain in the TARDIS while he and Tegan proceed (beat_66036502d57a9aea), creating a cause-and-effect chain where established role dynamics and leadership decisions drive the action."
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.
