Just sticking my head in for a while.
If CSI kills Sara, I think CSI may loose some of iis regular wievers. Maybe not because killing the GSR-relationship or the charcther itself. I think it is purely an ethics related question, in some ways. As a previous poster pointed out: The "A" Team does not only get treated like the "A" Team. Jorja is underpayed i comparisation to her other colleges. And Sara is just as importnt to the show as Catherine or maybe even Ecklie! If TPTB kills her because she is asking for more money, I think that a lor of people will identify with her and stop watching CSI (Ok, maybe record it or watch re-runs). Also, it seems like such a pathetic cause. "You want more money, Jorja? We are so sorry, but we do not have that kind of money even though we are one of Americas Top Rated Shows and has been that for the last 7 years. And just because you asked, how do you feel like getting killed of? Cause that's what we are going to do with Sara."
Aslo, going back ro the ethics related topic. A lot of people will identify with her, i'm sure. But also, I think that the major part (like me) will think TPTBs reasoning to illl Sara is lame. And I fully agree.
