Nick was seated in the waiting room of Dr. Colby's office when Sara emerged from her appointment. There was something about the expression on her face that gave him a sinking feeling in the pit of his stomach. He smiled at her as he stood up. "Hey."

Her smile was a bit more restrained. "How's Harley?" She was struggling with some of the things that she had talked to Dr. Colby about and she wasn't really sure how to tell Nick that some of them had to do with him.

"He's doing what most cats do at least fourteen hours a day. He's sleeping." Nick tried to keep the tone of his voice light even though he could tell Sara had something weighing on her. There was just something about her demeanor that had changed in the short time she'd been in that office.

They walked out to his Denali and as they climbed in, Nick glanced over at her. "How did your appointment go?" He studied her as he watched a few emotions flicker across her face.

"Uh, good." She turned towards him for a moment and then glanced out the window before letting out a deep breath and looking him in the eye. "Nick?"

The tone in her voice hit Nick like a ton of bricks. He forced a smile onto his face. "Yeah?"

There was something in his expression that caused her to hesitate. Instead of saying what was on her mind, she smiled. "Thanks for taking Harley back to your house."

Her smiled put him a bit more at ease, but there was something in the back of his mind that told him she hadn't said what she'd intended to. He grinned at her. "No problem. Me and the little guy are starting to come to an understanding."

Sara glanced at his forearm and winced, reaching over and touching the scratches that hadn't been there when Nick had dropped her off at Dr. Colby's. "Oh, Nick." She furrowed her brow and looked up at him. "I'm sorry he did that."

Nick chuckled and put his hand over hers for a moment, giving it a squeeze before starting the ignition. "Sara, it's ok. It's just a couple of scratches."

The conversation fell into a relaxed banter and by the time they arrived at the lab, they were laughing about something Harley had done when they were trying to catch him to go to the vet.

"I swear he knew where we were going." Nick chuckled.

"The look on your face though was priceless." Sara was trying to keep from laughing. "I didn't think he could fit behind your refrigerator."

Warrick glanced up from the break room table with a curious expression as Nick and Sara walked in. When he noticed the angry red scratches on Nick's forearm he winced. "Nick, man, what did you do to your arm?"

Nick glanced over from where he was pouring himself a cup of coffee. "Sara's cat scratched me."

Warrick looked a little confused as he glanced over at Sara. "Since when do you have a cat?"

She smiled and glanced at Nick. "Since this morning. Nick got him for me."

Warrick suppressed an amused smile. "Well it doesn't look like he likes Nick very much."

Nick chuckled in protest. "Hey, me and the little man are getting along just fine. Despite the fact that now I need a new shower curtain."

Just then, Grissom walked in, his brow knit together in concentration. He glanced up and quickly took in who was in the room. "Good, you're all here. Catherine's already out on a case. Warrick and Sara, I need you to check out this missing persons report." He handed Warrick the slip. "Nick, you're with me." He glanced up at Nick who for a moment look confused before putting on his game face.

It was the first time since Sara had threatened to kill herself that she had worked with anyone besides Nick.

Sara felt a bit detached as she and Warrick drove to the home of their missing person. As he drove, Warrick glanced over at her. "How are you doing, girl?" His tone was sincere and full of concern.

She smiled at him. "I'm ok."

Warrick raised an eyebrow at her. "You sure?" It wasn't that he didn't believe her; he just wanted to hear it again.

She let out a deep breath. "I'm fine. I just have a lot on my mind." She glanced out the window.

"I'm a good listener." Warrick offered. He knew that she was seeing a counselor, but he also knew that outside of that she really hadn't talked to anyone but Nick about what had happened.

She gave him a tired smile. "Thanks, Warrick. I really am fine. I'm just thinking about some things that I talked to my counselor about."

As if reading between the lines, Warrick continued. "Is everything going ok at Nick's?"

The corners of her lips twitched further upward. "Yeah, it's fine." She looked at him for a moment and there was just something about his expression that made her relax. "It's mostly fine."

Warrick looked worried for a moment. "You want to talk about it?"

She bit her lower lip. "I think I need to stay at my apartment." She trusted Warrick and knew that whatever she told him wouldn't leave the vehicle.

Warrick looked a little surprised. "Are you ready for that?"

"I don't know." There were conflicting emotions on her face.

"What's going on?" His voice was thick with concern.

Sara let out a deep sigh as she looked at Warrick. "I'm starting to have feelings for Nick and I'm really confused."

Warrick's face registered no surprise.

Sara continued. "I think he is too. I think maybe me staying there is just making it worse."

Warrick nodded. "Are you going to be ok staying by yourself?" He knew what she was trying to say, but he was still concerned for her wellbeing.

"Well, I have Harley." Sara smiled. "Nick thought that if I had a roommate, it might help when I go back to my apartment."

Warrick smiled. "I don't see any scratches on you."

Sara chuckled. "He does seem to only do that to Nick, but he did bite my nose." She glanced out the window. She really didn't want to move back to her apartment quite yet, but she also didn't want to cross any relational bridges with Nick prematurely either. Especially when it seemed that at least some of what she'd been feeling could be attributed to the fact that they'd been together almost nonstop since he'd pulled her off the railing.

Warrick glanced over at her again. "Have you told Nick that you want to go home?"

Sara shook her head. "Not yet. I'm not sure I'm ready." There was a double meaning in her words that Warrick seemed to fully understand.

"You know I'm here for you, don't you?" Warrick reached over and squeezed her shoulder.

She smiled at him. "Yeah, I do know that. Thanks."
