Great catch, Rose! That line on 21 serves as a starting point reflecting Rachel’s attitudes which when contrasted to her actions in the end underscore the breadth of her arc.
This is one of the strengths of dialogue, when it reveals character. And when you can set up where a character is relative to their ongoing psychological journey, that can serve as a touchstone for comparison for down the road after they’ve changed. “Oh, I could *never* do that!” Then 90 pages later, guess what? They’re *doing* that!
Thanks, Rose, and again nice catch!
