Why These Connect
The narrative assertion
"Marius's initial capitulation to Lowe's ultimatum (beat_6c051da331887a86) sets off a chain of events culminating in Marius's possession by the virus and his injection of mini-Lowe into the Doctor's brain (beat_defa2dcf7e0540e7). This connection underscores the escalating stakes and the Doctor's internal vulnerability."
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.
