Title: Who Knows What?

Disclaimer: It's not mine, and short of my last birthday wish coming true, it never will be

Summary: Two of our favorite CSIs are involved and aren't telling the lab. But who really knows what?

Spoilers: Slight spoilers for season two, but it's about…half a sentence?

A/N: Doing this from Catherine's point of view gave me a little bit of trouble… which might have been a blessing in disguise because it spurred me to try and write a fic from her perspective, which I'm working on now. Even though it's not finished, I really like it (especially because, of course, I made it Snickers). But I digress…

Chapter 3: Catherine

(Catherine's PoV)

They think they're being discreet. Bless their hearts, they really do. But we all know. Well, most of us do, anyways. Warrick's got himself convinced "his man Nick will never make a move". But I think he already has. So we made a bet, with a tidy sum of money riding on it.

And if that gives me a ready-made excuse to talk and joke with Warrick, so be it. It's not like I'm complaining.

But back to Nick and Sara. Because I'm sure they're Nick and Sara. The way he looks at her when he thinks no one's watching. The way she smiles at him in a way she's never smiled at anyone. They're together alright; I just never found any real proof. Which, of course, is what Warrick insists on.

Greg agrees with me, at least. And for as much as he liked Sara, he told me he was genuinely happy for them. He would have told them, but they don't know that we know. I figure between Greg and myself, we'll find a way to drag it out of them.

I wonder, sometimes, why they didn't tell anyone. I mean, we're all close here. Even Sara and I have been known to get along pretty well on occasion. Didn't they think we'd be happy for them? But I figure they're either working things out between the two of them, or worried about Grissom.

Now, the man is a genius, and I'll be the first one to admit it, but I gotta say, he's completely clueless in this case. He told me once he just doesn't get people, and I'd have to agree with him.

I wonder what he'd think if he knew, though. He's always been… not as close with Nick as with the rest of us, and even if it wasn't apparent to anyone else, he did care for Sara. He just didn't know what to do about it. Sending that plant was the closest he'll ever get to doing anything about it, and that wasn't even his idea. I just can't help but wonder, now, how he'd react.

Personally, I think it's a pretty good match. Nick and Sara balance each other out. Sara's always been a bit reserved' for a while it seemed liker her only hobbies were working massive amounts of overtime and reading forensic journals. She was turning into another Grissom, which could have been her way of getting close to him. It wasn't exactly a huge secret she harbored some kind of feelings for him, and imitation is the sincerest form of flattery, right? But lately she's been smiling and actually going home after shift. I overheard her, once, suggest to Archie an old drive-in movie venue when he was asking around for first date ideas. Nick's really gotten her to open up and leave the lab behind when she clocks out. Which I am all for, because one Gil Grissom is plenty.

And she's done wonders for Nick. He'd always been a bit insecure. Grissom's approval seemed to mean more to him that it did to Warrick or me. I know he's the baby or a rather extensive family; and he probably came to Vegas with that "eager to prove himself" mentality. Vying for attention must come naturally to him. Now, though, when he gets a bit attached to a case with a child having been…taking advantage of, it's Sara who calms him down; leads him away from the evidence for a (much needed) break.

And that goes both ways. I don't know why, but I've noticed Sara's always been a bit sensitive to abuse cases; battered women and children. Now nick's the one who she leans on. He's the one who drags her away, insisting she needs "a walk to clear her head".

I'm not stupid; the last time that happened, I followed them. Their 'walk' was limited to a brief stroll down the hallway and a pit stop behind a bay of lockers. I had my proof.

So I smiled and tracked down Warrick. He agreed to double the bet no problem.

End Chapter 3

A/N: Of the first three, this one was the hardest for me to write. I don't really know why… ah well. Reviews make me giddy, and (for those of you wondering) the next chapter is an insight into the strange mind of one Gregory Sanders :D
