Is this the same actress that played Mackenzie before? I don't really care for her and don't see why Billy is so ga-ga over her. I wasn't watching regularly back then, just occaisionally when I was off work and happened to catch the show. Can anyone give me more background on their history? I know they were going to marry then found out they were "cousins" when Jill ended up being Katherine's daughter. But that is about it.
