"Hey, Cal," Eric greeted his colleague as he entered the ballistics lab

"Hey, Cal," Eric greeted his colleague as he entered the ballistics lab.

"Hey. What've you got?" she asked and smiled at him.

"I just visited Alexx and she gave me a little something for you. She pulled the bullet out of the victims head," Eric said and held a little plastic back in front of Calleigh's eyes.

She gave him a sweet smile in return. "Thanks, Eric."

Eric let his hand sink to the table and locked eyes with Calleigh. Her sweet smile changed into a shy one. She held his gaze until she heard a loud bang. They both looked away and turned toward the door where the noise had come from.

When they saw what caused the noise they couldn't help but laugh. Ryan sat on the floor, papers lying all over the floor around him. In front of him stood Valera as she apologized. "I'm so sorry, Ryan. I didn't see you." She had a guilty look on her face.

Calleigh and Eric looked again at each other and agreed silently to help them with the mess on the floor.

"What happened?" Eric asked as they stepped out of the room.

"I was thinking about some evidence I just found. I was on my way to you and happened to crash into Ryan as he was carrying these files." She gestured around them and then looked guiltily again at Ryan. "I'm really sorry."

"It's ok," he mumbled and started to collect the paper. "Now I have to rearrange them again," he groaned.

Calleigh knelt down beside him and helped him to get the paper back in order. Soon Valery and Eric followed to help them.

A few moments later Natalia walked up to them and shot them a strange look. "What are we doing?" she asked.

"Oh, I thought it would be fun to drop 10 case files on the ground," Ryan answered sarcastically and shot Valera an evil glare.

"I see," Natalia answered as she started to walk past the group.

"Talia, you really could help us here," Ryan said.

She laughed. "I didn't want to take any fun away from you," she teased.

"Haha, very funny."

"But seriously, how did this happen?" Natalia asked.

"Valera bumped into me." Ryan told her the short version of the story.

"Oh," she replied as she arranged some papers and laid them on a pile for one of the files.

When Eric and Calleigh reached for a few papers that lay in front of them, their fingers slightly touched. They looked at each other, a shy smile forming on Calleigh's face. Their look lasted a moment longer than it had to and Eric ran his fingers lightly over Calleigh's.

Calleigh broke the eye contact and looked down, a light flush creeping over her cheeks. She pulled her hand away from Eric's and arranged some papers. Eric tore his gaze away from Calleigh and started to pull up some papers as well.

Calleigh and Eric's little moment didn't go unrecognized. Natalia had looked up just as they had gotten lost in each other's eyes. She had watched the situation closely, a smile forming on her lips. Calleigh blushed lightly when she noticed the knowing look on Natalia's face.

A few minutes later they were done picking up the paper. Calleigh was the first to get up. "I have some work to do," she said as she excused herself and vanished into her lab again. The others excused themselves as well and soon all CSI's were back at work again.

Calleigh was just about to make a phone call when she heard movement behind her. She turned around and saw Eric standing in the doorway.

"Hey," she greeted. "How long have you been standing there?"

"Oh, just a few minutes," he replied. "I like seeing you work." He shrugged when Calleigh shot him a questioning look.

"So, um, did you get the gun?" Eric asked.

Calleigh grinned. "Of course. Did you get anything?"

"Yup," he replied.

Calleigh raised an eyebrow at him. "You wanna tell me what it is?"

"Depends…" he teased and stepped closer to Calleigh.

"…on?" She decided to play along.

Eric took another few steps towards Calleigh until they were only inches apart. Her heartbeat quickened a little and she could feel Eric's breath on her face.

"That depends on who buys me coffee tomorrow morning."

"In that case," Calleigh said and forced herself to tear away from Eric. "I'm not interested in that evidence." She turned around and leaned over her desk again.

Eric sighed. "Well, in that case I can't tell you what I have." He stepped close behind her and leaned over her to bring his moth close to her ear. "Are you really sure that you don't want to know what I have? 'Cos it's really interesting…" He whispered.

Calleigh shivered lightly. Eric didn't even touch her and she couldn't think clear. "Eric," she whispered without turning around to face him.

He placed both hands on the table, one next to each side of her body. "Yes?" he replied. "Are you sure you don't wanna know what the evidence is?"

"Hey guys, I think…"Natalia stormed into the lab and wanted to say something but trailed off when she saw Calleigh and Eric. "Am I interrupting something?" she asked.

They spun apart and looked sheepishly at each other and then at Natalia. Eric cleared his throat. "I um, I was just about to tell Calleigh about the suspect," he said.

Natalia raised her eyebrows. "Sure, whatever." Her eyes wandered to the case file in her hand. "I think I found something interesting and thought you should know."

Calleigh walked over to her, not only to take the file from her colleague but also to bring a little safe difference between her and Eric. "What did you get?" She asked.

"I went back to the crime scene with Ryan earlier and I found something that clearly was not there yesterday. I found a cigarette lighter under the closet in the hall."

"Do you think the murderer came back?" Calleigh asked.

"Maybe he was looking for something," Eric suggested.

"Yeah, maybe something that would give away who he is," Natalia agreed.

"So the question is what did we miss?" Calleigh asked. "Maybe we should go back there again. Our murderer got careless. Maybe he didn't only lose the cigarette lighter; maybe he left us some fingerprints as well."

"Maybe. You two should go back there and look around, see if I missed something," Natalia suggested.

Calleigh turned around and looked at Eric. "Sure," he replied. "Let's go."

"Just give me a minute. I'll get my kit and meet you outside," Calleigh said. Eric nodded and left the lab.

Natalia waited until Eric had left the room and then turned back to Calleigh. "Okay, what is going on between you two?" she asked.

Calleigh shot her an evil glare. "There is nothing going on between Eric and me. We're just friends." She rummaged through a few things, and then she grabbed her kit and walked towards the door. "I'm off to the crime scene now," she said as she walked past Natalia.
