Why These Connect
The narrative assertion
"Ian hinting about the 'surprise' next destination (beat_89920edcb1490dd8) leads directly to Ian being left alone with the Doctor. From there, the Doctor reveals the TARDIS is trapped and brings a somber tone (beat_bd3182d1415eb13c), creating a contrast between the light tone and seriousness."
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.
