I as well, hope they have some tender moments with Sara and the girls on CSI, I however disagree on the 'relationship' between Sara and Cath. I never saw any chemistry between them zilch.
In "Nesting Dolls" when they had that confrontation in the hall and Sara was disrespectable, and Ecklie called her in the office and read her the riot act, then stated "And when you return you'll apologize to Cath" she goes
"NO I won't" and never did. In S/3"Crash & Burn" with the fiasco between Sara and Hank, Cath did offer to buy her a beer, but the situation was tense. They worked on serveral cases but were, to me off the mark on friendly banter, like she had say with Greg and that ep. [Nesting Dolls] he goes "I've always had Sara's back" , and lest we forget Warrick, who in the early days were a bit cold with on another. Grissom had her spy on him, and he was miffed off, and told her "Don't go talking behind my back" and after that if went smoothly with them. The "pig experiement, how they worked so cool on it, she even cleaned up the mess afterwards. In "Fannysmackin' how she was so concerned about Greggie, and was there for him. She did cover for Cath when she got mugged and drugged, and did her own crime kit, but only like one co-worker would do for another. And on Wendy when god forbid she mentioned Grissom in some context, and Sara snapped "I don't know what your talking about" and gave her the cold stare, like she does so well. I hope now maybe the writers will have Sara become closer with the other women on the show, I just always saw the strong bond she had with the guys on her team over the women
