Why These Connect
The narrative assertion
"Romana reassures Merak about Astra's oùabouts and insists he return to Atrios with Shapp. This leads to Merak's interactions with Astra in the Zeos Transmat area, where she manipulates him into feeling concern and distrust, ultimately setting up her later betrayal."
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.
