I too love that Ken Olin is finally in front of the camera. I enjoyed their scene together!
I see Kitty and Robert falling out over the way his kids treat her. He will let them do it because he is a father first and he wouldn't want to hurt his wonderful children. Then he will realize too late that he should have put a halt to it sooner, that he finds that he really truly loves Kitty, that he has allowed them to be super brats,....but it will be too late because Kitty finds that she doesn't really like his kids anyway, that she is totally mad at Robert, and that she deserves better.....But she will find out that she is pregnant and then will resent Robert not wanting to be a father again and that will "put paid" to their marriage.
