Title: Who Knows What?

Disclaimer: If you recognize it, then I don't own it

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

A/N: I mulled over the idea for a little while before trying to write this out, and this chapter I had to re-write a couple of times. I guess starting was the hardest, because the rest came pretty easily, even if it took a while to get down on paper. Anyways, enjoy :D

Chapter 1: Nick

(Nick's PoV)

We decided, at first, not to tell anyone, because we weren't sure exactly where this was going. I sure knew where I wanted it to go; this was something I'd been thinking about for a long time, but it was new for both of us. After all of the flirty banter and ignored tension (the good kind, of course) between us we'd finally just pushed each other over that line dividing friendship and…

Well, I'm not sure, really. Involved, I guess you'd call it. Sara all but lives at my house, and I'm just crazy about her, and she always tells met he feeling's mutual between trading kisses. But we haven't done anything yet. The very big anything, if you catch my meaning. And it's hard because we usually sleep it the same bed with Sara snuggled up to my side.

But we're taking things moderately slow, and I'm perfectly ok with that. This way it's comfortable and not rushed, and frankly, I don't think either of us is quite ready for that. I mean, Sara's had a pretty bad track record what with Hank and that whole unspoken attraction to Grissom, so she's basically been taught she doesn't deserve a functioning, healthy relationship. And after Kristy… I mean, it's not like I loved her, but I was close. If things had been different, maybe I could have. She was special. But after she died, it's not like I've been looking to jump into bed with anyone.

For which, I might add, Warrick's taken to teasing me about.

And that's kind of weird. He doesn't know; none of them do. Sara, I mean, she likes to rationalize things, and we sat and talked about it. Somewhere between smoldering kisses on the couch we realized it was simpler if it was, at least for now, just us in the relationship. Greg would joke, Warrick would tease, Catherine would dote; they'd all mean well but Sara'd feel overwhelmed. I would too.

Plus, there's Grissom.

We talked about that, too, and she assures me that it never went past infatuation. He was a mix of the father and the confidant she'd never had. Her feelings got jumbled.

And I believe her when she kisses my nose and tells me that the past is gone and "she's with me now and forever, and that's all that matters". She means it; the way she says it leaves no qualms, and that makes me falls that much harder for her.

You know, for working at the number two lab in the country, the rest of the gang isn't too observant of the change in the nature of Sara's and mine relationship. I don't think they notice a thing. Although, even before, she and I laughed and flirted and swapped innocent touches (a hand on my shoulder, my lingering fingers when I handed her coffee) and a lot of people, including a few suspects, thought we were together.

But that hasn't some up in a while. We're discreet and professional at work, at least while we're on the clock. Break time is often spent in the locker room behind a bay of rarely used lockers, or out in the parking lot, our roaming hands hidden by our department issued Denali's.

There've been some close calls, of course, but that just makes it all the more tempting for me to snag her from processing evidence with Catherine for a brief, but immensely enjoyable ren de vous in the parking lot.

And, mind you, I've never heard her complain.

End Chapter 1

A/N: Next chapter is Sara's point of view. Let me know what you think of this one, though :D
