It was the worst kind of day in law enforcement. The kind you never want to have. The kind where one of your own is the victim. Detective Cyrus Lockwood was running an errand. He stopped to deposit a check at the bank. He never got out. During an armed robbery, he pulled his gun to protect a woman and her young son. He never got a shot off. He was shot in the back. He died before he hit the floor.

Grissom and Catherine were the first CSIs on the scene. Catherine could tell that something wasn't quite right with Grissom, but she didn't push it. Warrick, Sara, and Nick arrived a while later. Grissom didn't hear them come in. It was Catherine who finally got his attention to let him know they needed him to tell them where he wanted them to start. He took a look around and assigned Sara to come with him to the vault. She rolled her eyes and looked over at Nick for a fraction of a second before following Grissom to the vault. Nick and Warrick assumed their own assignments and Catherine just stood there a bit bewildered at Grissom's behavior.

Grissom was all business in the vault. He didn't mention the dinner invitation, and Sara felt relieved as she went to work photographing the scene and then began the process of reassembling the safety deposit boxes that had been blasted open.

Nick analyzed the bullet trajectories from where Detective Lockwood was shot and where one of the police vehicles had been struck. Warrick went over the surveillance cameras.

Grissom and Catherine left the scene to follow up leads. Warrick took the evidence that he had collected back to the lab. Sara remained in the vault working at reassembling the safety deposit boxes to their pre-blast arrangement. Nick continued to trace the path of the bullets using laser guides. The trajectory took him to a building across the street where he was able to find GSR on a chair that he believed had been used to steady the rifle that made the fatal shot to Lockwood.

Quite some time later, Grissom and Catherine returned to the scene. Making their way into the vault Catherine commented on how well Sara had reassembled the safety deposit boxes. Only one was missing. Now they had to determine who it belonged to and what was in it.

Nick and Sara returned the lab, having processed everything they could. They ran into Warrick in the break room. Grissom popped his head into the break room and suggested they all go home and get some rest because he wanted them in early next shift. It had been a long shift and they were all exhausted. The trio made their way out to the parking lot and they each climbed into their respective Tahoes and went home.

Only Grissom and Catherine remained from the night shift crew. Catherine kept stealing glances at Grissom as they worked, suspecting that something was wrong with his hearing, but he kept covering up and she wasn't going to push. She'd known him long enough to know that wasn't a good idea. Several hours later, even they left the lab and made their way to their respective homes.

A few hours before the beginning of the new shift, the whole CSI crew was assembled in the break room. Greg, who had come back to work after being released from the hospital, had joined them. Nick had decided to pick up Chinese for everyone since he was pretty sure they weren't going to be getting much of a break that day. As they ate, the atmosphere seemed very familial. Grissom on one end of the table, Catherine on the other. The rest on the sides, as if they were the kids. In a way they were. Grissom and Catherine had been there the longest and the others were constantly learning new things from them.

As they sat there eating, they discussed the case before them. Greg commented that the results he got from the DNA testing were like the Mongolian Beef container. Empty. He teased Warrick with a pair of training chopsticks. It was good to have Greg back in the mix.

Catherine asked Grissom what he made of all of this. He commented that the robbers were experts at robbing banks, not in concealing evidence. He then contemplated his fortune cookie and asked if anyone knew how they were made. Nick piped up eagerly, "Oh, I do."

Sara just smiled at him, remembering the program they had watched on the food channel together. "Of course you do."

Nick began to explain, "The dough is put through a press like a tortilla, the machine then folds it in half and a woman places the fortune in the middle, then the machine folds it over again, sealing it inside before baking. And that's how it gets inside." He winked and pointed at Sara before eating his next bite of Mongolian Beef. She smiled.

Grissom replied, "That's the answer," and then walked out of the break room with a fortune cookie in hand, the rest of them just sat there dumbfounded, watching him walk away.

Catherine knew that Grissom was usually onto something when he wandered out of a room with a look on his face that she had learned was just determination. She tracked him down to see what he had found. Grissom had found a fingerprint hidden inside the remote for the detonators, much the way a fortune is hidden inside of a fortune cookie. A while later, Catherine and Grissom met with Jacki in the fingerprint lab. It was this fingerprint that began to lead them to a killer.

Warrick, Nick, and Sara remained at the lab working through the mound of evidence that they had collected. Nick found Sara in the computer lab a while later, her eyes fixed on a computer screen. "Hey, Sara. Do you want to go grab a bite to eat at the diner?"

Looking up blinking she replied, "Yeah. Where's Warrick?"

Nick replied, "Uh, he's tied up working on something with Greg."

She smiled and got up from the workstation she'd been sitting at. Wincing for a second, she realized she had a developed a kink in her neck. She rolled her shoulders and her neck trying to loosen it up a bit.

"Neck sore, Sara?" Nick asked with a look of concern.

She smiled at him, "Yeah, I think I've been hunched over that computer too long. Let's go grab some food. I'll be fine."

With that they headed toward the parking lot. Noticing Sara still trying to loosen her neck as she climbed into the passenger seat of his Tahoe, Nick looked at her with concern and asked, "Sara, are you sure you're ok, you look like you're in pain."

"I'll be fine, Nick. I just need to loosen it up a bit, that's all." Sara winced.

Nick wasn't convinced, but he drove the Tahoe out of the lot and headed toward the diner. About halfway there, Nick asked, "How's it going with the search?"

Sara turned to answer him and let out an audible, "Ouch!" as she turned to look at him, and grabbed her neck.

Nick pulled the SUV over into the parking lot of a park, took his seatbelt off, and turned toward Sara. "Sara, turn your back to me."

"Ok, why?" Sara took her seatbelt off and began to question as she turned her back to him.

Suddenly, Nick's fingers were massaging her neck, looking for the knots that had formed as Sara had sat hunched over the computer. "That help any?" He asked.

The only sound out of Sara was a contented, "Mmmm." She leaned into Nick's neck massage, her neck loosening up under his touch. His hands moved to massage her shoulders too. Sara felt the tension in her shoulders dissipate. With Nick's hands on her shoulders she leaned back into his chest and let out a contented sigh.

In a slightly husky voice Nick asked, "Better?"

Leaning her head back onto his shoulder, she replied in a soft voice, "Yeah."

Sara's left arm reached up behind her and snaked around Nick's neck, playing at the base of his neck with her fingers. Nick encircled Sara's waist with his arms, pulling her closer to him. Sara rested her free arm on his, caressing it with her fingers. Sara could feel Nick's breath on her cheek. She felt his breath in her ear as he whispered, "Sara, we shouldn't do this."

Sara's hand left the back of Nick's neck and cupped his cheek. She continued caressing his arm. She whispered, "Why not?"

Nick reached up and cupped Sara's hand as it rested on his cheek and turned his face to kiss her palm. "That's why."

Sara closed her eyes and entwined her fingers with Nick's and pulled their hands down around her waist, "But I like it, Nick. I like you."

She felt Nick's breath on her neck, her heart rate quickened. She felt soft warm kisses on her neck. "Nick." She whispered.

"Sara." Nick murmured, continuing to plant soft kisses on her neck, working his way to her jaw.

The phone on Nick's belt rang. Uttering a curse and releasing Sara from his embrace, he answered the phone. "Stokes. Yeah, Warrick. We'll be right back." He hung up the phone, a look of frustration clearly etched on his face. "Sorry, Sara. We need to head back."

She had moved back to her side of the seat and refastened her seatbelt. "It's ok, Nick."

Neither one of them looked at the other on the drive back to the lab.
