Why These Connect
The narrative assertion
"The sight of Adric trapped in the energy web (beat_9f0b39b992e4cb4f) drives Mergrave and Ruther to investigate a noise, leaving the confrontation unresolved (beat_0fdbdc4b249d8828), creating a tense pause before the Doctor's final intervention."
About Causal Connections
