Nick stood in front of his locker stowing his gear when Warrick and Sara walked in. He glanced up and noticed Warrick gesturing with his eyes to Sara. Nick gave him an imperceptible nod. Warrick stowed his gear and quietly left the locker room.

Sara didn't say a word as she went to her locker and put her things away.

Nick glanced over at her, "Sara, are you feeling better?"

She glanced at him for a second, trying to act natural and not doing a very good job of it, "Uh, yeah." Sara stowed her gear and looked up to find Nick watching her. "Uh, did you want something?"

Nick was brought out of his daydream, "Uh, sorry, what?" He looked at Sara, somewhat embarrassed that she had caught him watching her.

Sara looked at Nick curiously. She wondered what he thought about her saying his name in her sleep. All of a sudden she felt like she was going to throw up again. She grabbed the nearest trash can and did just that.

Catherine walked in just as Sara finished. She looked at Nick for a moment and then walked over to Sara, "Hey, Sara, are you ok?"

Sara nodded, "Yeah, I'm fine."

A doubtful expression crossed Catherine's face, "Uh, Sara, I don't think throwing up qualifies as being fine."

"She's right, Sar. Maybe you've got the flu." Nick added, his face etched with concern.

Sara let out a deep breath and took a bottle of water out of her bag. She took a sip and replaced the cap before responding, "I don't have the flu."

Catherine raised an eyebrow, "Are you pregnant?"

A look of disbelief crossed Sara's face and then a chuckle escaped her lips, "No, I am not pregnant!"

"Sorry, I'm just concerned," Catherine offered.

"Hey, I'll see you guys later." Nick decided that now was not the time to talk to Sara. He headed out of the locker room and toward the parking lot.

Sara looked over at Catherine who still looked at her with concern, "Catherine, I'm fine."

Catherine raised an eyebrow, "Sara, if you're sick you can potentially contaminate a crime scene."

Sara rolled her eyes slightly, "Catherine, I'm not sick, at least not with the flu."

Catherine looked at her curiously, "Care to explain?"

Sara let out a deep breath and looked at Catherine with a serious expression on her face, "Not really."

Catherine crossed her arms in front of her, "Sara, if Grissom sees you throwing up, he'll pull you from the field. If you don't have the flu, what's going on?"

Sara narrowed her gaze at Catherine, "If you say a word, I'll kill you."

Catherine chuckled, "Fine. Now spill it."

Sara's face had a sheepish expression, "I feel like throwing up when I'm around Nick."

Catherine looked perplexed, "Nick makes you sick?"

Sara shook her head, "No, I mean yes." Sara looked directly at Catherine, "Cath, I think I'm in love with Nick and the thought of him finding out is making me sick."

Catherine laughed.

"What?" Sara queried somewhat annoyed.

"Sara, you sound like you're in high school with your first crush." Catherine had a bemused grin on her face.

"Crap, this is so embarrassing." Sara closed her eyes and rested her forehead on her hand.

"You know, you could talk to him." Catherine replied, stating the obvious.

Sara didn't open her eyes, "Oh, I'm sure that would go well." Her voice was thick with sarcasm. "I can see it now, 'Oh, excuse me, Nick, while I throw up on you, but I think I'm in love with you.' I don't think so, Cath."

"Stranger things have happened, Sara." Catherine tried to offer assurance without revealing Nick's confidence.
