When they arrived at the diner, Nick and Sara sat on opposite sides of the table from each other and exchanged silent glances, Warrick and Catherine took notice of their interaction and exchanged smirks, and Grissom was lost in conversation with Greg about the latest advances in DNA testing on maggots.

The waitress was familiar with the group, they hardly varied their order, and they were served very quickly.

As they ate, Grissom noticed that Nick and Sara were unusually quiet, "Nick, Sara, are you feeling ok?"

Sara looked over at Grissom and mumbled, "Yeah, I'm fine. I guess my head still hurts. I'm a little dizzy."

Nick glanced at Sara and then at Grissom before answering, "Me too."

Grissom raised a curious eyebrow, "How is the case coming?"

"Nothing new, Gris." Nick replied for both of them.

Catherine and Warrick took in the scene between bites of food remaining silent.

Greg interjected, "I haven't gotten a match from CODIS yet, but then, the system has crashed a couple of times today."

Grissom looked at Nick and Sara with concern, "You said you had a concussion, did you get checked out?"

Nick shook his head, "I told you, I think we'll both be fine."

Grissom was about to say something when Catherine interrupted, "Well, you can't be left alone with a concussion. Both of you are coming home with me. You can crash on my sectional, there's room for both of you and I'll check on you every couple of hours to make sure you're ok." She smiled very mom-like. Warrick tried to suppress a smile at Catherine's genius idea.

Both Nick and Sara started to protest, Grissom interrupted, "Catherine's right. If you have a concussion, you shouldn't be alone, and you should be woken up every couple of hours."

Sara was too tired to continue to protest, but the thought of being that close to Nick made her extremely nervous, especially after Nick almost kissed her on the roof.

Nick glanced at Sara, he too was tired and his head hurt. He wasn't sure it was such a good idea to be that close to Sara while trying to sleep, but if he tried to explain why it wasn't a good idea, he'd have to share far more than he wanted to.

They arrived back at the lab and Catherine stood there with arms crossed in front of her as Nick and Sara made their way into her vehicle after each retrieving a bag of spare clothes they all carried in their Tahoes. Grissom went back inside, claiming he had forgotten something, but everyone knowing he was really going back to work. Greg was slightly disappointed that he couldn't come up with a reason to stay at Catherine's also, so he made his good-byes and headed home. Warrick exchanged a silent look with Catherine that spoke volumes, and he knew he'd get a full report from her at the beginning of next shift.

As they made their way into Catherine's house she turned and asked them, "Is there anything I can get for you? You can make yourselves at home. Lindsey is staying at my sisters, so it should be pretty quiet. I'll just get you some pillows and blankets." Catherine headed off to the end of the hall to the linen closet and Nick and Sara headed into the living room, sitting down on opposite ends of the sectional trying not to look at each other.

Catherine tried not to laugh as she entered the living room and noticed Nick and Sara not looking at each other. It occurred to her that this is how kids acted when she was in high school when they wanted to dance, but didn't know how to ask. She smile pleasantly enough and placed the pillows in the middle of the sectional, so their heads would be together, and handed each of them a blanket. "If you get cold, I'll leave a couple of extra blankets right here."

Nick looked at Catherine, "Catherine, you really don't need to do this, I'm sure I'm fine. I've just got a little headache. I don't want to put you out."

Sara joined in, "Yeah, Nick's right. I mean, besides this bruise, I'd be fine at my own house."

Catherine gave them both withering glances, "You're not putting me out. You both have a concussion and you need to be checked on. Don't argue. I'll check on you in a few hours."

With that she walked down the hall to her bedroom and shut the door. Nick and Sara just looked at each other. As they met each other's gaze, Nick grinned and Sara blushed.

"Sara Sidle, you're blushing again." Nick quipped.

"Shut up, Nick." Sara was feeling uncomfortable and she averted her gaze from Nick.

Nick's voice softened, "Hey, Sara. I'm sorry." He came over and sat next to her.

Sara looked at him, "No, Nick, I'm sorry. I didn't mean to be short with you. I'm just feeling a little awkward after earlier."

Nick lowered his gaze and let out a deep sigh, "I'm sorry, I was out of line. I shouldn't have tried to kiss you."

A look of confusion crossed her face, "But you said you wanted to."

He looked at her with a smile tugging at the corners of his mouth, "Yeah, I wanted to. I still want to, but maybe we should talk about this first."

Sara blushed, "What do you want to talk about?"

A lopsided grin crossed Nick's face, "Sara, I care about you. You're my friend, we work closely together. If we started something, what if it didn't work out?"

Sara looked at him with a slight smile and a raised eyebrow as she leaned back into the couch, "So, what are you saying? I'm not worth the risk?"

Nick smiled, his eyes twinkling, "I didn't say that."

Sara leaned forward and touched the side of Nick's face, letting her fingers trail along his jaw line as she glanced from his eyes to his lips, "Then shut up and kiss me, Nicky."

A grin spread across Nick's face. His hands cupped both sides of Sara's face. His thumbs caressed her cheeks. Sara smiled and licked her lips unconsciously. Nick's eyelids drifted closed as he pulled Sara toward him. Sara's eyes closed and she could feel Nick's soft warm breath on her lips.

"Hey, I forgot to tell you guys that the towels are in the hall closet in case you want to take a shower," Catherine had come out of her room and was walking down the hallway toward the living room. Nick and Sara jumped apart and tried to act natural as Catherine entered the room.

"Uh, thanks, Cath." Sara replied. "I think I'm good right now."

Nick grinned at her, "Me too."

Catherine raised an eyebrow suspiciously. "If you want to watch a movie or something, the DVDs are in the entertainment center and the remote is right here. I've got the entire Disney collection." She gestured toward the entertainment center. Catherine looked at Nick, "Sorry, I don't have cable."

"Catherine, we're fine. I told you that you don't need to go to all this trouble," Nick replied stealing a glance at Sara.

Catherine smiled at the pair, crossing her arms in front of her, "It's no trouble. I'm going to try and catch some sleep, but if you need anything, you can wake me up. I'll check on you in a couple of hours." She turned and headed back to her bedroom wearing an amused smile.
