Chapter 2

Callen's phone rang, pulling him abruptly out of his sleep and from a dream of a certain brunette with blue-green eyes and a body he was looking forward to getting to know for real, not just in his dreams.

"What?" he answered gruffly.

"Grumpy this morning aren't you? Get out of the wrong side of the bed?" Sam's voice greeted him. A voice that was most definitely not asleep, or one from his dreams.

"What is it, Sam?" Callen asked, ignoring his partner's questions.

"Maybe it was the wrong bed," Sam added.

Callen sat up, rubbed his face with his other hand and looked at the clock beside his bed, whilst thinking how right Sam was. Most definitely the wrong bed.

"Sam, it's five thirty in the morning. What's wrong?" Callen knew they had to be at work early but not this early.

"Coming to get you. Hetty called. Wants us at the boathouse in half an hour. Apparently something's up," Sam answered, his tone now slightly more serious.

Callen could hear the sound of the car door closing and his brain clicked into gear. If Sam was leaving now, that would give him ten minutes to get himself dressed, awake and alert enough to handle any wisecracks Sam might continue to throw at him on the way. He pushed the sheets away that were tangled around his legs and stood up.

"I'll be ready," Callen replied.

"Just you? No mysterious companion?"

"Goodbye Sam," he added firmly and hung up. Usually Callen didn't regret telling Sam about the women he occasionally dated. This time he might. The teasing normally just rolled off him. With Lucy it was different. She wasn't like the rest.

Five minutes later, showered, but not shaved, Callen was dressed and ready. He grabbed an apple from the fridge and walked out to the kerb to wait for Sam.

Two minutes later, Sam arrived.

"Didn't want me to see the new girl?" Sam teased him.

"She's not here, Sam. What's the deal? Hetty tell you anything?" Callen asked, hoping to send Sam's mind in a different direction.

"Something about an NCIS agent being in trouble and needing our help."

"Who?" Callen frowned. One of their own? He was momentarily glad he'd only had an apple, as his stomach rolled briefly at the memories of finding and losing Dom.

"Apparently one we've never met. Kensi and Deeks are meeting us there. Assuming Hetty will be too."

"That's all she told you?" Callen queried, the frown still in place.

Sam turned to him and rolled his eyes. "You want to try and get any more out of Hetty before she's ready to tell us, feel free to call her."

"As if you don't want to know," Callen shot back.

"Yeah, but I'm not stupid enough to annoy our intrepid leader with questions at five thirty in the morning."

"But you are with me?"

Sam glanced sideways at him briefly before turning his attention back to his driving. "Is that your way of telling me to shut up about the girl that you refuse to name?" Sam asked.

"Guess you're right. Not stupid after all."

Sam looked at him briefly, a frown on his face, but turned back to focus on driving. He refrained from commenting any further during the drive, he knew his partner well and knew he wouldn't get anything out of him easily. Sam decided to wait until they were inside to resume his questioning about the girl. He didn't want to have to tell Hetty this early in the morning that he'd scratched the paintwork on the Challenger because he had been distracted with grilling Callen on his current dating situation.

They arrived at the boathouse to find it empty. Callen walked over and started the coffee machine going. He had a feeling he was going to need a constant stream to keep his mind alert and focused on the mission, and not on tonight or this weekend; his dreams were still vivid in his mind and he didn't want to get distracted if there was an agent in trouble. He frowned slightly, wondering if he might have to disappoint her, okay both of them, if this got too involved.

Sam came up to him and leaned against the wall whilst they waited for the coffee.

"So, when are you going to dump this one?" Sam asked.

Callen's frown deepend and he turned to his partner, confused. "What?"

"Miss No Name. It's been five weeks hasn't it?"

"So?" That feeling of regret resurfaced and he was definitely glad that this time he had kept her name to himself. Callen didn't really know how to tell Sam that this time it was different. He didn't even know if Sam would believe him and he wasn't entirely sure what would be worse. Sam's teasing about his lack of a decent woman or what advice might come from his married partner if he had one. Teasing or advice? Callen couldn't decide which would end up being the lesser evil.

"So, five weeks. What's wrong with this one?" Sam asked.

"Nothing," Callen admitted.

"Nothing?" Sam echoed, a shocked expression on his face.

"Nothing is wrong with her okay," Callen repeated. She was smart, funny, easy going and gorgeous. She liked him, what she knew of him anyway. Most of what Callen had told her had bordered on the truth.

"Nothing?" Sam sounded like he was stuck on a one word track on a record.

"Back off, Sam," Callen warned seriously. This was still new to him. Having someone he was interested in sticking it out with. Not trying to find the slightest reason to stop seeing her.

"Just saying, six weeks is your limit, then you're out of there."

Callen was about to respond when Kensi's voice came from behind them.

"Sorry to interrupt the dissection of Callen's love life, or coming lack of one, but we have a mission."

Callen turned around, a sharp retort on the tip of his tongue, which disappeared as his eyes settled on a brunette, not Kensi, with blue-green eyes and a horrified expression on her face.

"Special Agents G Callen and Sam Hanna, this is Special Agent Mika Davis."

Callen couldn't take his eyes of her as the name Kensi had said rolled around in his head. Mika? Special Agent? Oh, this was not good.

Sam nodded and then nudged him. Callen finally looked briefly to his partner who frowned, but his gaze returned quickly to the woman who he'd been dreaming about this morning. Who he wasn't expecting to see until tonight.

"But you two already know each other," Deeks commented. There was an amused tone to Deeks' comment that got on Callen's nerves instantly, like Deeks knew something.

"Sort of. We're dating," Special Agent Mika Davis, more commonly known to him as Lucy, replied, still looking at him.

Callen noticed her look wasn't entirely friendly and he thought back to what she might have overheard. Inwardly he groaned as he remembered the last thing Sam had said before Kensi had spoken up. "Just saying, six weeks is your limit, then you're out of there." Add to that Kensi's follow up and it really didn't look promising for a happy reunion right now.

"Were," Callen heard Sam mutter under his breath as he too, seemed to pick up on the tension between the two of them. He turned to glare at Sam. So did Lucy … Mika. Hell, he didn't even know what to call her right now. Callen turned back to her to catch the tail end of the glare she had shot Sam, only to have it turned on him.

"She's the one you've been dating?" Sam asked.

"Yeah," Callen admitted in a tone which he hoped would shut Sam up. Right now wasn't the time. He didn't want to be answering Sam's question, not when he had a whole lot he wanted to ask Lucy, he'd stick with that for now. Their relationship had suddenly got a whole lot more complicated than he ever imagined it would. They'd both been lying to one another. The main question now was, how much?

Lucy turned to Kensi. "Is there a bathroom here?" she asked. Callen could hear the tension in her voice.

Kensi nodded and pointed in the right direction. With a brief glance at him that barely gave Callen a chance to register the pain in her eyes, Lucy turned away and walked off. He could see her holding her hands clenched beside her. She was mad. Though she wasn't the only one who had been lied to. Seems she hadn't even given him anything close to her name. They moved away from the coffee and sat down.

"She's cute Callen," Kensi said with a wink. "Didn't think brunettes were your type though, nor badges for that matter."

"Kenz, don't. This is not good. When's Hetty getting here?" Callen asked. He wanted to know what was going on with this mission. Sam had been told an agent was in trouble. He really didn't like idea that his Luce, and yes, he did consider her his, might be that agent and hoped that this was just a coincidence; a painful, awkward coincidence that would require one hell of a talk, but at least she would be safe.

"She's on her way," Deeks answered. "We called her once we had Mika."

Callen frowned at the familiarity he heard in Deeks' voice. "You went and picked her up at her place?" he asked. He wondered how that would have gone if he'd given in and stayed.

Kensi nodded. "Yeah, Hetty called and practically ordered an immediate extraction. She was still asleep and we had to break in so we didn't disturb any neighbours."

Deeks raised his eyebrows suggestively and Callen's eyes narrowed at Deeks, wondering what had prompted that look. He also had to fight off the urge to have his fist come into close contact with Deeks' face at the thought of him being in her bedroom.

Callen struggled to fight off the very unprofessional thought. Deeks had been there with Kensi, it wasn't like he'd been there alone.

Lucy came out of the bathroom and Callen watched her head straight to the coffee machine, determinedly avoiding looking at him. Sam eyed him and Callen shook his head to ward off any further questions. Callen stood up and moved to join her.

"So, you're not in construction," Lucy stated bluntly.

"And you're not a temp," Callen countered. He got himself some coffee and watched her dump spoonful after spoonful of sugar into hers.

"Not exactly," Lucy replied.

Callen put his hand on hers when she got up to six. She liked sugar in her coffee, but this was way more than normal.

Callen heard her sigh. She pushed the coffee cup away and started again.

"Anything else you haven't told me Lucy, sorry Mika?" he asked.

"Like you've told me everything, Agent Callen," Lucy replied sarcastically.

"At least I gave you the right name."

Lucy continued to avoid looking at him as she spoke. "Middle name's Lucille. Personally these days, I prefer Lucy over Mika or Mikeyla. It was my cover as well, okay. It wasn't that far off." Lucy took a sip of the coffee, now she had managed to control it to just two sugars. She set it down and turned to him.

"You know what, maybe we should just assume that everything we've ever told each other was a lie," Lucy said.

Callen felt an ache in his chest when she finally looked up at him after she had finished; she looked so sad. Maybe this wasn't entirely a lie for her either.

"Not everything," Callen said.

"So what was real? You did have a dog when you were five?" she asked with a roll of her eyes.

"No." Callen pulled her close. "This," he added and kissed her, a brief but passionate kiss that had him wanting more. He could only hope she still wanted him too.

"That, was very real," he added.

Lucy looked like she was about to cry and Callen frowned. She stepped back from him and turned away, hiding her face from him.

"So, was this weekend going to be goodbye?" she asked.

"What are you talking about?" She was so confusing right now. Her reactions, her questions, her tone. Nothing made sense at the moment to him. She'd lied to him as well. Surely this wasn't just about that. She should understand where he had been coming from.

"Six weeks," Lucy reminded him.

Damn, she had heard the conversation. Callen had been clinging to the vague hope that somehow she hadn't heard what Sam had said. That would definitely explain the horrified look on her face when he'd turned around. That would explain her reactions. Yes, she was hurting but it wasn't necessarily because he'd lied to her about who he was.

"How were you going to do it?" Lucy asked. "Leave in morning, never come back. Were you actually going to say goodbye or just disappear?"

When Callen didn't answer, Lucy turned back to him. Anger and pain marred her beautiful eyes and Callen felt a sharp pain in his chest as guilt flared that he had caused this.

"Is that all this was?" Lucy demanded. "You just wanted to get me into bed and then leave?"

She was so far from the truth it was almost funny.

"If that's all I wanted," Callen said, "this wouldn't have gone past the first night."

"You arrogant son of a -"

Callen yanked her back into his arms and kissed her. He didn't give her a chance to protest, he knew what she liked, knew what she couldn't resist. He didn't pull back until well after he felt her melt against him, return his kiss and wrap her arms around his neck, a soft moan escaping her mouth as she did.

"First night," Callen said, his voice a tad breathless too. She certainly wasn't the only one affected by the kiss and the attraction between the two of them. "You wanted it as much as I did."
