Fox helped buildCSI: Crime Scene Investigation’s initial success as Sara Sidle, a crime scene investigator who ends up marrying her team leader, Gil Grissom (Petersen). The duo led the original series forfifteen seasonsbetween 2000 and 2015, ensuring a long life for the franchise, which just returned for a revival last year. InCSI: Vegas, a new team led byPaula Newsome’s Maxine Roby uses the latest forensic technology to solve crimes in the titular city, counting with the support of legacy cast members such as Fox and Petersen.

While Fox’s return was well-received by fans, the starannounced on Twitterthat “after much deliberating, I have decided not to ‘Sidle up’ for CSI Vegas.” Fox underlined how “CSI has always been a love story” to her, and that means following Petersen in his departure. As Fox explains it, “I personally just can’t split Sara and Grissom up again. So goes Grissom…..So goes Sara. Wherever they go, they belong together.” Ina previous interview with Collider, Fox had also expressed a similar sentiment about the characters in her initial return to the series, saying:

“For Sara to come back without Gil Grissom, in a sense, would have meant that, once again something had happened to that relationship. That it had ended or fallen apart. And that would have been really tough. I think I’m really attached, Jorja’s really attached to the idea of Sara and Grissom, if they were going to return, to return together.”
