I think Kate needs to take a good look at herself in the mirrow. She needs to realize that you can't belittle your partner all the time and not expect they are going to go and find someone to talk to (even if it is a friend) The interview they did clearly showed that Jon really didn't want to do another season of their series. She may end up wishing she had listened.
Maybe Kate needs to take a long hard look in the mirrow and realize she has been behaving like a first class witch.. I'm not surprised that Jon was out and about. She has the most over inflated ego one is likely to see. Maybe a little more respect for Jon's feeling would help.
