I just read this article in EW magazine this week. I read Destiny's second post about Jorja posts, but I'm pretty sure this pertains to spoilers. If not, sorry, and feel free to move it!
Also, I'm copying it by hand, because I do not have a scanner!
'CSI' scoop: Sara's back! Will Grissom be next? <----The Ausiello Files
Less than a year after reuniting in the jungle with leading man William Petersen, Jorja Fox is heading back to CSI this fall--alone. But don't take Fox's five-episode return to mean that Sara and Grissom's happily-ever-after was a bust. "They're absolutely together," insists executive producer Naren Shankar, who nonetheless says Sara will drop hints of trouble in paradise. "We're talking about a couple of very independent individuals who have decided to share their lives together. The first few months of that for any couple are a very wird adjustment."
So, if not a breakup, what does prompt Sara to revisit the Vegas strip? Shankar and fellow executive producer Carol Mendelsohn maintain it was not a mandate from CBS to stem last stason's ratings slide. That said, the pair concede that the back-to-back-to-back departures of Fox, Gary Dourdan, and Petersen, combined with the arrivals of Laurence Fishburne and Lauren Lee Smith, took a toll. "The family had disintegrated a little bit," Shankar says. "We had people off in their own bubble, and we want to restore that family [feeling]. And Jorja's helping with that." Adds Mendelsohn: "Sara comes in and brings everyone together. And she helps Catherine understand that as the [new] leader, she needs to make the team cohesive and really fire on all cylinders again."
Might she get an in-person assist from Petersen? "You never know when Grissom will show up on CSI," teases Mendelsohn. "The theme of [season 10] is family. And he certainly is part of the family -- a big part of the family." I'll take that as a yes.
Okay. Wow. So they need Sara to help Catherine restore the team? WTF? They can't do that without her?
