I completely agree!!Kate was actually entertaining, to me. She just doesn't care. Nick has been a thorn in not only her side, but her son's, grandson's, and was trying to take her great-granddaughter away. I liked that she didn't pretend to be upset. That, to me, would have been over the top.
If the writers have any since.....Now that they have given Kate such a callus attitude toward Nick's death.....Hope should hone right in on that, asking the question......"if you hated him so much, why was he working for you?" It certainly makes her look like a good candidate for the 'who done it list'.
