Flora Belle returns home after serving time—she took the blame when her adopted sister Clara killed someone at their mother and Henry's urging. Instead of a reunion Flora meets coldness; Clara's presence triggers panic and she collapses with chest pain, rushed to hospital. A Physics Research Institute credits Flora's theoretical model for her early release and offers her a research position. Flora accepts and plans to leave in a week, choosing to walk away while the family's cover-up and Clara's condition remain unresolved.
