Garcelle asking Dorit how shes doing with the seperation

I thought that Dorit's reaction to Garcelle asking her how she's doing with the separation in front of all the women was completely justified. Garcelle has made it very very clear that she does not like Dorit, constantly makes jabs at her, and does not want to be her friend. We've known this for a while. She is completely entitled and valid in not liking Dorit, but to act shocked and surprised when Dorit doesn't believe her that she had genuine intentions in asking her how she was doing after the separation in the middle of a huge fight with Kyle was laughable. Obviously, Dorit would not believe her. I feel like Garcelle stirs the pot and then cowers (much like her bestie Sutton). I always wondered why she is such good friends with Sutton when they're so different, and Sutton sucks, but now I see that they have the same behavioral patterns, and it makes sense.
