Why These Connect
The narrative assertion
"The tolling of the Cloister Bell (beat_80009ec4eadd563c) in the Tardis prompts Tegan's investigation, which escalates to her being trapped as the police box dematerializes (beat_ee941bfa78244657), demonstrating the Bell's role as an urgent signal leading to a pivotal event."
