Catherine and Warrick were working slowly and methodically as they processed the scene of a smash and grab. It was a slow night in Vegas and Catherine at least was thankful. Without the odor of body fluids to assault her senses, she had managed to not throw up the entire shift thus far.

Warrick glanced over at her curiously. "Cath?"

She looked up from where she was dusting the remains of a glass display case for fingerprints. "Yeah?"

"Are you going to tell him?" Warrick was concerned for his friend and he knew her propensity to be independent and want to do things on her own. As much as he knew that she didn't think Chris was the fatherly type, Warrick knew that if it had been him, he would want to know.

She furrowed her brow. "I don't know." She continued dusting for prints. "He's just not the kind of guy that I'd want to have to be around forever. Of course, it's not like Ed really was either." She glanced up at Warrick again. "I guess you can't really choose who you fall for."

Warrick was never one to back away from tough questions. "Did you love Chris?"

Catherine let out a heavy sigh. "I don't know if I would call it 'love." She chuckled. "Lust definitely. That man was good." Her tone became more serious. "But one of the reasons things didn't go any further with us than they did was because he was a little too excited that Sam Braun was my father."

Warrick looked confused. "You told him?"

Catherine shook her head. "No. We were out one night and we ran into Sam. He volunteered the information."

"And that's why you never let him meet Lindsey?" Warrick was trying to put the pieces together.

She smiled softly. "Something like that." She met Warrick's eyes across the display case. "Sam Braun is a part of my past that I can't change and I don't want to get drawn back into that."

"You're not that woman, Cath." Warrick assured her.

"I know that, and you know that, but there are some people in town that won't let it go." Catherine took a few photographs of the prints she'd been able to raise on the glass.

Warrick studied her for a few moments. "It's too bad I'm not a little bit older."

Catherine looked up at him with a slightly bewildered expression as a smile played at her lips. "You afraid of an older woman?"

Warrick chuckled softly and shook his head. "You're the hottest woman I know, Cath."

Catherine shook her head and turned back to processing the scene, smiling at how Warrick knew just how to boost her ego. "Yeah, well now I'm a hot pregnant woman. I thought Nick was going to choke on his coffee when I told all of you."

Warrick chortled. "I think some of it came out his nose."

"Sara was pretty quiet." Catherine commented as she applied lifting tape to one of the prints.

"Yeah, she was." Warrick considered that for a moment. As much as Sara had become more like her old self, there was still something telling him that deep down things still weren't quite right.

"Although, she didn't seem too surprised." Catherine quipped as she lifted another print.

Warrick chuckled. "You did throw up in front of her."

They lapsed into silence for a while as they continued to work the scene, Catherine finishing up on the broken display case. "I'm done." She glanced over at Warrick who was dropping something into a bindle.

"Yeah, me too." He stowed the bindle into his kit and stood up. As they gathered up the rest of the evidence they had collected, they headed out to Warrick's Denali.

Catherine glanced over at him as they stowed their kits in the back of the truck. "Hey, Rick, can I ask you something?"

He smiled at her. "You know you can." He shut the back of the rig and leaned back against it.

Catherine tilted her head slightly. "What would you do?"

He pursed his lips together. "About Chris you mean?"

She nodded.

Warrick put his hands in his pockets. "If it were me, I'd want to know." His expression was soft. "But then, I like kids."

"So you think I should tell him." Catherine considered his words.

Warrick shook his head. "I didn't say that. I just know that if it was me, I'd want to know."

She let out a deep sigh. "Maybe I should."

"Then again, you didn't want him meeting Lindsey." He studied her for a moment. "Maybe there's a deeper reason for that."

Catherine furrowed her brow and nodded. After a long moment a smirk played across her face and she looked at Warrick out of the corner of her eye. "It's too bad you're not a little bit older."

Warrick let out a chuckle. "Are you afraid of a younger man?"

"Not at all." She grinned.

"Whatever you decide to do about Chris, I'm here for you. I hope you know that." He put an arm around her shoulder, giving her a quick hug and kissing the top of her head.

"I know." Catherine smiled as she pulled away.

After returning to the lab and checking in the evidence, Catherine headed to the break room in search of something to drink.

Sara was sitting on the couch with her eyes closed holding a cup of coffee in her hands.

Catherine looked at her quizzically. "You ok, Sara?"

Sara seemed a bit startled as she looked up at Catherine. "Yeah. I guess I'm just tired."

Catherine invoked a motherly look. "When did you sleep last?" She could tell that Sara was beyond exhausted.

The younger CSI had a slightly blank expression on her face. "I'm not sure."

Catherine smirked. "You know you loose your edge after the first sixteen hours."

Sara nodded. "Thanks for the concern, Cath."

"Seriously, Sara, you need to catch some sleep. You're not going to be any good to your case." Catherine dipped a bag of peppermint tea in a cup of hot water.

Sara let out a resigned sigh and leaned back into the couch. "We have no suspects and no leads."

Catherine looked at her quizzically. "I thought you suspected the boyfriend."

Sara set her cup of coffee down on the table in front of the couch and looked up at Catherine. "Our vic wasn't our vic. She was in Jamaica eloping with her boyfriend. Our vic was her identical twin sister."

"Well that's a twist." Catherine sat down on the couch next to Sara and put a comforting hand on her shoulder. "Sara, I'm sure that you and Nicky will figure this out, but right now, you're not doing yourself, your case, or your victim any good by working yourself into an exhausted state."

"I know." Sara rubbed her temples.

Catherine studied her demeanor for a moment. "Sara, is the case all that's bothering you?"

There was something in Catherine's tone that made Sara look over and speak the words she'd wanted to say to someone for quite a while. "No."
