Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The alarming spike in the machine's reading during Barnham's procedure (beat_9ea558718d56ec8a) directly leads the Doctor to connect Kettering's drowning to the machine's power, reinforcing the connection between the two deaths and demonstrating the escalating danger (beat_53187329f5da8024). The machine's unpredictable behavior when used on Barnham becomes evidence for the Doctor's claims around Kettering's demise."
About Causal Connections
