A/N: arg! Just what I need, another story. But this idea has been bugging me for over a month! So I finally had to write it down. I might not update much, on account of school and stuff. But, I had to put this up. Well, enjoy and remember to review!

The

girl's hair blew in the slight Las Vegas breeze as she stood staring at the large building in front of her. Here she was, the place that could be the answer to everything she had been looking for. This could be the key to figuring out her mother's mysterious path, and the identity of her father. Her stomach fluttered as she slowly walked towards the door of the lab building.

Kaylie tried to keep her breathing normal as she opened the door of the Las Vegas Crime Lab and neared the receptionist. "Hello. My name is Kaylie and I would like to speak to someone from the night shift." Kaylie didn't know much about her Mom's past. She did no that her Mom had worked on the night shift at the crime lab though. The receptionist looked up at Kaylie, slightly annoyed.

"Sorry, they're busy. Little girl, go home. You shouldn't be out anyways."

"Listen lady, I don't know who the hell you are, but you better let me see the damn people." Kaylie (or Kay as she was called) shot the receptionist a glare, or as her friends called it, her 'infamous death glare'. She heard a low chuckle coming behind the receptionist and looked up to see an older blonde woman looking at her.

"Its ok. Let her come in." the receptionist rolled her eye's as Kay shot her a "ha-ha" look.

As Catherine walked by the receptionist to check something, she heard what sounded like someone arguing with the uptight woman. She looked over to see a young girl yelling at the receptionist. But what really caught her attention was the glare the girl shot. Catherine had seen that glare before. Now that she thought of it, the girl looked familiar. She had slightly curly brunette hair that reached her shoulders. She was thin and about 5'5. Looking about 14 or 15, the girl was actually quite pretty. Catherine couldn't place the girl, but she looked so familiar...

"Hi." Kay said, trying to control her nervousness. The blonde smiled, easing her nerves a bit.

"Hi. I'm Catherine. So, you needed to talk to someone?"

"Yes. My Name is Kaylie and I need to talk to the supervisor or something of the nightshift." She followed Catherine into an office.

"Ok. Wait here while I get Gil Grissom, our supervisor." As soon as Catherine left, Kay started looking around. A picture hanging on the wall caught her attention. She walked over to get a better look. A small smile formed on her face as she studied it. It was a group picture, with the lab team, she guessed. Her Mom had her arm slung around two other men. She looked so happy. Happier then Kay had ever seen her before. Of course it could have been the fact that the two men next to her were hot, Kay thought with a small laugh.

"Um, hello." She whirled around to face an old man.

"Hi. I'm Kaylie, Kay for short."

"Gil Grissom. Catherine said you wanted to talk to me."

"Yah. You see, I am 15 years old. Before I was born, my Mother worked here, on this shift. She left before I was born. I never knew who my Father was. My Mom had to come to a convention here and brought me along with her. I really want to find out who my Father is, so I thought perhaps you could help me find out." She smiled hopefully at Grissom, who looked at her thoughtfully.

"And who is your mother?"

A clash filled the locker room as Nick Stokes flung open his locker door. It had not been a good night, to say the least. The murder had been a messy one, and to make things worse, he had had to go into a pool to gather evidence. As the locker hit the next locker, a picture fluttered to the ground. As Nick picked it up, despite his bad mood, he couldn't help but grin. It was a picture of him and Sara, taken by Greg 16 years ago at the annual lab softball game. Less than a year later, his life had fallen apart. He quickly tried to push thoughts of that from his mind. He was upset enough as it was. He didn't need thoughts of that to bring his mood down even more.

"Who is your mother?" Grissom was very curious to know whom this girl was talking about. She smiled.

"Guess I should have told you that first thing. My Mom's name is Sara Sidle." Grissom's face went white.

"Wha-wha-what did you say?" the mans voice was filled with astonishment and disbelief. Kay eyed him.

"My Moms name is Sara Sidle. Do you know her?" she deliberately spoke slow, as if talking to a dumb person. With shaky fingers, Grissom picked up his phone and dialed.

"Catherine. I need you to come to my office NOW. I don't care what your doing, just get in here." He hung up the phone. A few moments later, Catherine joined them in the small office.

"What the hell Grissom?"

"Kay, tell Catherine who your mom is." Kay rolled her eyes.

"Sara Sidle." Catherine's face paled to a color matching Grissom's.

"Sara. My God. So, she's here? In Las Vegas?"

"Yah, a convention."

"Um, I think we should go to the break room, where we can sit down." Grissom nodded and got up. He motioned for Kay to follow him.

"Take a seat, make yourself at home." Kay took a seat on the small couch. Catherine and Grissom sat in chairs across from her.

"Hey, what's going on in here? Who's this?" Warrick had walked into the room for some coffee. He cautiously sniffed the pot and got a cup. "Want any? It's Greg's stash."

"No, Warrick, sit down. This is important. This is Kaylie."

"Kay." She interrupted Grissom.

"Right. Kay. Kay Sidle." Grissom watched as Warrick's facial expression turned to one of shock.

"As in relative of Sara Sidle?" His voice was meek, for he already knew the answer.

"As in daughter of Sara Sidle." Catherine confirmed it. Warrick sunk down beside Kay.

"What about Sara?" Greg had joined the large group in the break room.

"Greg, you might want to sit down."

"Why? Gris, what's going on? Why do you all look like you've seen a ghost?"

"My God! Why the hell is it so shocking? Why are you so shaken up by the fact that my Mom is Sara Sidle? What happened?"

-Thump-

"Told him he should have sat down." Grissom commented as they tried to lift the passed out Greg onto the couch.

"I'll get some water," volunteered Warrick. He briskly exited the room. In his rush to find water for his friend, he didn't see Nick. Which resulted in him crashing into the other man.

"Whoa, where's the fire?"

"Greg fainted."

"Why?"

"Because Sa-Something happened." Warrick knew how close Nick and Sara had been. He didn't want to upset his friend. He found what he was looking for and turned to go back to the break room. Unsurprisingly, Nick followed.

"What's going on?" He looked curiously at the group in the break room. Catherine and Grissom were still pale, Greg was passed out, and a strange teenager was sitting down, a look of confusion etched on her pretty face. "Who's this?"

"Nick, sit."

"Why?"

"Just do it." He eyed Catherine but obeyed.

"Nick, please don't freak out. This is Kay. Her mother is um, her mother is Sara."

"Sara. Not..." Nick's voice was barely a whisper.

"Yes. Sara Sidle." The room seemed to spin for Nick. He got up.

"I, I need to get some fresh air." He didn't wait for an answer.

"Well, what now?"

"We call Sara. She has some explaining to do."

"Yah." Agreed Kay. She reached for the cell phone clipped on her belt and dialed. "Um, hi. Mom? Ya, I'm fine but um, please don't get mad. I'm at, um," With and exasperated sigh, Catherine grabbed the phone.

"Hello Sara. Guess who. Yah, that's right. Get the hell down to the lab. You have some explaining to do." she snapped the phone shut and looked at Kay.

"So, um, who's you Father?" Greg had woken up.

"That's why I'm here. To figure it out. She never mentions her past."

"Where do you live? What does she do?" Warrick wondered.

"We live in Nashville. She is the supervisor for the crime lab there." Catherine chuckled.

"Is she still antisocial?"

"Yes! I keep telling her to get out more! I even tried to set her up once. Here's a tip: Never try to get a secret setup past a CSI." She laughed.

"Sounds like Sara hasen't changed." Grissom's voice was wistful. He wondered who was the Father. He didn't think she was involved with anyone. Hell, he was sure she was in love with him. In fact, when she left, he had been trying to gather the courage to ask her out.

Nick leaned against the truck in the parking lot. He was trying to hold back the tears that were threatening to fall. He just couldn't get the words out of his mind.

"Her mother is Sara"

Nick wondered who the Father was. He didn't know what to think anymore. He jumped as he heard the sound of a door close. He hadn't even heard the car come up and park. He looked over to see a woman walking from a small car. His heard skipped a beat.

"Sara?" His voice was filled with hope and sadness. She turned to face him. She broke into a smile, despite her sour mood.

"Nick?" she walked up to him only to be scooped up into a large hug from him. She hugged him back tightly, reluctant to let go.

"So, um, what's been up with you?" Sara asked as he released her. Her voice was soft. He looked at her.

"Sara, stop trying to avoid the obvious." She sighed. He continued. "So, you're a Mother."

"Yeah. Kay."

"How old is she?"

"Just turned 15." Nick leaned back against the truck. That would mean she had the girl when she was still working here.

"So, who's her father?"

A/N: WOW! That's the longest chapter I think I have ever written! Go me! Lol. Yes, I left you with a cliffy. Though I think some of you have figured out who the Father is. Lol. Well, remember, reviews make me update much faster. So, review!
