Dolly gets more characterization in these moments, highlighting the contrast between her behavior with and without Sam around. This indicates that she cares more about how she’s perceived by other men than by her own husband, whom she sees as a failure in this moment especially. The accident puts additional strain on their already faltering relationship, setting up future conflict. In contrast, Rose doesn’t try to run away from what’s happened, opting to support her father at his lowest moment. She feels more adult as a result, and this affects her development later on.
