There were two Ichebs? I did not know this. I don't know the detail of Kate v Jeri. I can't imagine it's nice for the lead actor to hear that they aren't enough for the ratings and they need to bring in a younger and sexier woman to spice things up. We'd all be a bit jealous. I just checked on Wikipedia (so may not be true) but the introduction of Seven didn't really do much for the show ratings-wise beyond her first few episodes.
