I don't actually remember the line you mentioned. I remember her saying something about Grant having not hidden the sledgehammer. Is that what you meant, or is there something I'm forgetting? (I binged the series rather quickly, so it's very possible I missed something.)
I wish the show had leaned more into the issues of privilege that it only occasionally seemed to recognize--and then out of a clear sense of having to do so. But I thought Kidman and especially Grant were great.
