Why These Connect
The narrative assertion
"The Doctor's suspicion that 'something was seriously wrong on the station' after examining the dead crew member (beat_b377a0eed79b8a1c) directly leads to his later conclusion that the infection is not natural and may involve poison (beat_471b84c7ecafeaa8)."
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.
