Why These Connect
The narrative assertion
"The Master's act of picking up the hypodermic needle (an instrument of deception) directly leads to the Doctor's later suspicion about the Master's 'death' not being genuine. This moment plants the seed of doubt that the Doctor acts upon when he questions the Master's apparent demise."
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.
