AN: FBI Girl has a name. I'm sure it's a very nice name. But the nice name doesn't sound as fun as FBI Girl. Thanks to RebelByrdie for making me think of using FBI Girl. ...You know, I spent a good ten minutes laughing when I realized I was posting a chapter of a femslash story on Easter. Happy Easter, folks!

"Score one more for the good guys! Another mugger put away due to the valiant efforts of one Sara Sidle and Greg Sanders! Thank goodness Grissom gave us that case! The sheer difficulty would have had any lesser CSI begging for a hint!"

I smile at Greg's enthusiastic sarcasm. He's been like this ever since we caught the guy. When we first arrived at the scene, he kept his mouth shut regarding the ridiculousness of Grissom giving the assignment to both of us. Now he refuses to shut up.

Not that I can blame him. Grissom pulled him away from helping Catherine for this case. I'd be annoyed too. Though for slightly more complex reasons. If anyone dragged me away from spending time with Catherine…

"You aren't listening anymore, are you?"

Greg's mock-glaring at me, and I smile guiltily. "Sorry, Greg."

He rolls his eyes and goes back to goose-stepping to the break room. I follow him at a slower pace. When I enter the room he's already complaining to Nick and Warrick and FBI Girl. They're all chuckling good-naturedly at him.

Catherine's sitting at the table sipping her coffee almost reverently. Oh, to be that coffee… happy thoughts. Happy thoughts that have no place at work. Right. Sane thoughts aren't nearly as much fun.

"We're going out to celebrate finally catching the bastard after shift. You two want to come?"

I nod immediately. I don't have anything to do at home. Either Greg will go with them, or he'll be out with his neighbor, who actually is his girlfriend now.

I sit down next to Catherine, who seems to be in a world of her own. I clear my throat gently to let her know I'm there before asking the question. "So how did you end up catching the guy?"

She opens her eyes and smiles at me, but not before blushing. Odd… I thought we were done with her being uncomfortable around me? Oh well. At least she's smiling. She can't be too uncomfortable.

"Dumb luck. An officer off duty was wandering down an alleyway while the bastard was cleaning up his latest victim. Five minutes later he's in the back of a squad car."

She doesn't look too thrilled that luck was the only thing that caught him. "Well, at least you no longer have to deal with the FBI agent. That's something."

Her smile becomes rather fixed, and I wonder what could have caused that. "I might not like her, but you apparently do. You don't tend to send random people flowers for absolutely no reason at all, Sara."

She knows about that? "The flowers were from me and Greg. We, uh, felt like we owed her something."

"Why?"

I blush as the image of Catherine taking off her beautiful dress pops into my head. "You don't want to know. Trust me, Cath. You really don't want to know."

She looks suspicious. She places her coffee mug on the table and leans towards me, as if she's going to interrogate me. A split second before she says anything, Greg saves me.

"So, Catherine, where are we going?"

FBI Girl and I were voted 'least likely to spill the alcohol', so we get to grab drinks for everyone else.

"I never got to thank you and Greg for the flowers. What were they for, anyways?"

I smile nervously at her. "Er... you pulled Catherine away from a very fancy dinner."

FBI Girl smirks to me and nods towards our table. "Ah- you're into that then? I can't really blame you... though I've got to say- you're more my type." She gives me a blatantly flirtatious look and my face comes dangerously close to bursting into flames.

"Uh... no thanks." I'm too hung up on Catherine to consider dating anyone else.

FBI Girl takes the brush off well enough. "I figured. Can't blame a girl for trying, though, can you? You've really got a great body."

Before I can come up with some sort of reply to that, Greg calls out to us.

"Hey! Hurry up with the drinks before Catherine manages to shoot knives from her eyes!"

I look over to see him grinning at Cath. She's glaring at me and FBI Girl. Greg has a good point. I think if she could, she'd be skewering us right now. I shift nervously and move to grab some of the drinks. What did I do? She's been frosty towards me ever since we left the lab!

I sigh and roll my eyes. It's Catherine. That seems to be my answer to everything lately.

FBI Girl chuckles. "Damn. Your girlfriend is seriously possessive, you know that?"

Blood rushes to my cheeks and I smile awkwardly. "She's not actually my girlfriend." Why am I telling her this? I don't want her flirting with me the rest of the night. I quickly make my way back to the table. I don't want to know how she's going to respond to that.

The rest of the night- morning- doesn't go well as far as Catherine's temper is concerned. Everyone else is having a wonderful time, though I could do without FBI Girl and Greg flirting with me so much. For some reason, Catherine's mood seems to respond negatively to their actions. It must be the alcohol. I'm imagining things.

She finally snaps when FBI Girl starts stroking my arm. "Okay, that's it- you're coming with me." She stands up, grabs my other arm, and drags me towards the restrooms.

Once we're there she lets go of me, and I stare blankly at her.

What the hell?
