I have not watched csi much since Grissom left, and when I did I didn't post here often, only when events like this happen.
I'm going to try to stay on the topic of the spoiler.
First off, some of you asked why are they doing this?
You guys already know the influence that Grissom/WP had on the show. Grissom was a well liked character, and since his departure many fans have left, dwindles, we've lost writers, and that great CSI thrill that once was. No matter how much you may not like it, on some level you all have to agree that a big part of this was Grissoms departure. Because they can't get WP to come back, even to do the guest appearances that he mentioned, they have to find some way to keep a character that was so influential in some shape or form alive. IMHO I think that is a big reason why Sara is still on. She is a connection to Grissom.
Because he is no longer with us, having characters like Sara have drama with his mother and, god forbid his ex, then its TPTB's way of trying to compensate the loss of such a character, while hopefully explaining some loose ends. We still don't even know what happened in San Fran, how they got together, when they got married, where Grissom is and why is in Paris while his wife is in Las Vegas. We don't know. Not to mention that Grissom's past is still a little shady, he didn't talk about it much, and this is a way that we can learn more about Grissom when we don't have WP.
Its a little far fetched, yes I'll admit to that much. And I would have rathered Grissoms mother just be there, and not his ex. I mean three women who know Grissom personally and he is far far away. Smart man.
They can do this right if Sara knew that her mother-inlaw and friend was in town, and what ever happened at the crime place happened, she gets involved not knowing who was involved, and then you can bring the tension that comes along when sara realizes that the person that she claims is a suspect is the that friend who just happens to be someone who slept with your husband back in the day. The story line is tricky, and its indeed playing with fire, but it does have the potential to be a good episode. These characters are always getting involved with cases that involve them personally: Sara investigating the case where her boyfriend, Hank, gets almost killed by a car moving into a resturaunt, The team and Warick's death, Brass and Elli's friend, Grissom and all the Lady Heather episode (you know he tapped that), its been done, and those episodes were done well despite the character drama that was apart of it.
Lets wait and see...
(On an off topic note, I think that Sara's connection with Ray has nothing to do with her lost daddy, they haven't even talked about it as far as I am concern. In that case Grissom, Sara, and Warwick all have a connection because they lost their daddy (or didn't know them) when they were young. I think it is more so because Sara saw someone who was knew coming to the team during a rough patch, and took to him because she understood how that felt [when she came during the death of holly gribbs, no one liked her much] she's just being nice in my opinion. I see a level of respect, and she could take to him a little because TBTP decided they wanted the black version of Grissom, and made Ray very simular to Grissom in many ways, even down to dress in some cases. Just MHO)
