Why These Connect
The narrative assertion
"Romana’s realization that Vivien has a different metabolism (beat_f70396cb6679837a) motivates her to question Vivien’s habits in the cottage, leading directly to the discovery of citric acid avoidance (beat_1af1845ca083a74c). This is a logical investigative progression in Romana and Emilia’s research."
