Yes but there's no connection at all for me. As others have pointed out you had CC personally issues off set and falling out with Joss. And there is no reason why you can't have two female core cast members at the same time.Not saying it was Fred fault but it just to happed once Fred clam down form being how she was when come back to earth.
Also by no means blaming Fred as I propley be even more crazy had be in place like that for five years.
Well that's debatable. I'm a big Fred fan, but have come across a couple of people who are not so high on her. I don't see a reason why her and Cordy could not have worked together on the same show. I mean there doesn't seem to be a issue with having as many as three male core cast members.Only because Fred was so much better.
