Chapter 1 – The beginning

Sara Sidle walked through the halls feeling very bored. It was a slow night and she hated feeling useless. Grissom was doing something bug-related in his office, and although she knew he wouldn't mind her company, bugs were not really her thing. She went to see if Greg needed help, but he had everything under control, and he was blasting some weird music, so she just left smiling. She liked Greg. But, his sense of music was just too much for her that evening. Warrick was with Catherine working on a murder case in one of the Casinos, and Nick was doing his paperwork in the break room. She walked into the break room eyeing the coffee pot. It had a familiar look of bad and watery coffee.

"Don't tell me, Greg doesn't want to share tonight?" – she asked Nick who kept his head in the papers but smiled.

"Yeah, I think he has some secret place where he hides the coffee."

"Well, that's just rude. I mean, we would share with him, right?" – Sara asked as she poured herself a cup. Nick took his eyes from his work to look at her disbelievingly.

"Of course." – he said sarcasm dripping from his voice.

Sara sat next to Nick putting her feel on the table.

"Maybe we should talk to him, get him to realize the error of his ways."

"Well, I doubt I could convince him of any errors." – he leaned back in his chair looking her pointedly. – "However, I think you could. We all know Greggo has a crush on you."

Sara simply rolled her eyes.

"Very funny, Stokes. Are you suggesting I use my feminine charms to persuade him?"

"Well…yes." – Nick started to laugh as he saw an angry look on her face. Of course he knew she was just pretending.

"Well, I could just beat the hell out of him." – she shrugged as she took another sip. – "Well, this is really bad."

Nick stopped his laughing as he leaned towards her looking her straight into her eyes.

"Don't be mad at me saying this, but I don't think you could bit up Greg."

She didn't pull back from his stare, she only leaned forward.

"You don't ha?"

"A-a" – Nick shook his head.

"So, I guess you think I can't beat you either?" – she sounded very serious, which took Nick by surprise.

"I'm not questioning you abilities to defend yourself, but I don't think you could take me."

Sara's eyes became darker that usual. She broke the stare between them, and stood up.

"Maybe, you're right. – her voice trailed off. She wasn't going into that argument. Even if she knew she could take him. She could take even Warrick.

"Look, Sara, I didn't mean to…" – Nick started to apologize, but Sara stopped him.

"Nick, you shouldn't apologize. Seriously. We were joking around." – she put her best smile on and prayed this would be enough for Nick to drop it. He was very emphatic person, and she liked that about him. But, when she was concerned, she preferred being left alone.

"OK. Well, I should get back to the paperwork, so I can go home." – he said as he forced himself to look at the papers again. We still knew there was something wrong with her, but he decided to leave her be. He knew her well, and he knew she wasn't going to confine in him. And that bothered him every day…

Sara grabbed the remote from the desk and turned on a TV. The sun was going up, but it was still very early, so there was nothing on. She was changing the channels not hearing Grissom entering the room.

"There you two are. What are you doing?" – Although it was a slow night, he still didn't like seeing his staff sitting and doing nothing.

Nick looked up closing his folder.
"Well, I'm done! And just in time for breakfast! I think I'll just order two. I'm sooo hungry!"

Sara smiled at him, still changing the channels.

"You're always hungry. You know, I just figured out something. TV is a waste of time.
"

Grissom took the control from her hands and muted the sound.

"I could've told you that."

Both Nick and Sara smiled and knowingly looked at each other. There was no question in their minds that Grissom didn't watch TV all that much.

Brass entered the room looking like hell. He loosened up his tie as he approached the coffee maker.

"Please tell me, this is the good stuff."

"Sorry, Jim." – Nick said. – "Greg hides his stash. No more good coffee for us."

Brass sighed kicking back in his chair.
"Wonderful. And he decided to do that one night I need a good cup of coffee."
"Well, I was just discussing with Sara how she should use her feminine charms on him, but she declined." – he winked to Sara who was giving him a dirty eye. – "However, she said that she will beat him up, so, maybe we'll still get our coffee."

Brass chuckled. He was fond of Sara, but the picture of her beating someone up wasn't very plausible in his mind.

"Well, there's no need to hurt yourself, Sara. We'll survive on this dirty water."

Sara just smiled a little, still keeping a calm look.

"So, Brass, what's with the tired look?" – Nick asked.

"Well, I had to play a politician again, believe it or not. There is a circus in town and LVPD needs all men."

"You mean, there are days when the circus is not in town?" – Grissom asked playing with the remote in his hands.

"Yes, well, this is a special kind. With a lot of penguins." – he shook his hear rubbing his temples.

Sara's head shot up, having a strange feeling in her gut.

"Penguins?" – she gulped.

"Yeah. See for yourself." – he nodded towards the TV screen. They all turned around as Grissom turned up the volume. Sara's eyes grew wilder as she saw Presidential motorcade driving the familiar streets of Las Vegas.

"Well, what do you know…" – Grissom muttered. – "What are they doing in Vegas?"

"Well, apparently President Bartlett has some business to take care of in the neighborhood, so the entire family and some senior staff decided to make something off their weekend.

"The entire family?" – Sara barely got her voice up.

"Well, wife and the youngest kid. The one who's been kidnapped a few months back."

Sara's eyes started to tear, but she tried to regain control.

When she first heard Zoey was kidnapped the only thought in her head was that she let her down. She left her duty after Rosslyn, because she couldn't forgive herself for not reacting in time. But, now she regretted that she wasn't there with Zoey when she was kidnapped. Even though her assigned secret agent was shot, she couldn't help but wonder that something would be different with her there. She wanted to contact her, but leaving Secret service meant she had to leave everything behind.

TV screen showed footage of the President getting out of the limo with Mrs.Bartlett and Zoey in tow, secret service surrounding them. She saw another woman she didn't recognize with Zoey and her mind went back to Rosslyn.

FLASHBACK

She saw that big crowd again and she heard herself speak:

«I saw something!»

She saw herself looking around frantically, spotting the creepy boy looking up at the office building past her head.

She remembered Zoey calling her name:

«Gina?»

She remembered seeing that creepy boy looking at something, just in time as the skinheads in the office building raised their guns.

She remembered pulling Zoey down and shielding her from the gunfire, yelling, "get down, get down!"

She remembered talking with Leo McGarry:

"You got the girl in the car, Gina"

And she remembered her response:

"It was right in front of my face…"

END FLASHBACK

Her face looked like she was in trance and although the footage was over her eyes remained on the screen.

"Sara?" – Grissom called her. Nothing.

Nick looked at her and grabbed her arm.

"Hey, Sar?" – she instinctively grabbed back and in one move put Nick on the floor. Shock was written all over her face as she realized what she done.

AN: Now, I don't know if everyone knows the story from Rosslyn, so I hope that flashback explained a few things. And this is more CSI story (N/S), than the WW. Just a warning. Let me know what you think. Is it believable?
