Why These Connect
The narrative assertion
"Tegan's decision to return for the Doctor (beat_ce0663602509b5b8) sets off the chain of events where Range accompanies her, leading to Range being present when the Doctor and Tegan are pulled by the gravity beam (beat_ba48084f8acab7a5)."
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.
