As they stood on the dock watching other tourists preparing to swim with dolphins, Sara couldn't help but smile. So much had changed over the course of the last week and with only a few more days left in Cozumel, she wasn't sure she wanted it all to end. They hadn't really talked about the implications of their relationship on work when they returned to Vegas, but then a lot of things in that area had been changing already since it had become public knowledge that Catherine and Warrick were seeing each other. She reasoned that the fact that they were still seeing each other just made it that much easier for her and Nick and her smile widened a bit.

"Pretty cool, huh?" Nick was grinning like a kid at Christmas as he watched as one after another people slipped into the water, following the instructions of the proprietor as they patted dolphins swimming past them in the small lagoon.

"Yeah." Sara let out a sigh of contentment and looked over at him, studying his profile. The beard he'd been growing softened the strong line of his jaw and she noticed that when he smiled, he had crinkles in his face. He must have smiled a lot growing up and at that thought she felt a bit of a pang that her childhood had been less than ideal. She briefly wondered if Nick would still love her if he knew her secret, and she let out another sigh as she resolved that she needed to tell him. She wanted him to love her, but she wanted him to love her for all of who she was, not just some of the pieces.

If Nick noticed the faraway look on Sara's face, he didn't say anything about it just then. He simply slipped an arm around her waist and spoke softly in her ear. "So I was thinking, since we can't do this until tomorrow, why don't we rent a couple of mopeds and see a little more of the island, maybe we can stop by a pharmacy and stock up on a few things for later."

His last comment elicited a giggle from Sara and she looked into his eyes. "Are you always going to be this horny?" She arched her brows at him suggestively.

Nick smirked. "Well, when we get back to Vegas, I'll try and keep things under control while we're at work, but I can't guarantee I won't haul you off into the janitor's closet to have my way with you now and then if we get stuck working too many doubles."

Sara snorted out a guffaw. "Nick, have a little class. The backseat of my Denali is more comfortable and a lot more private."

Nick had to look at her a good long moment to tell whether or not she was kidding.

Sara giggled. "Gotcha."

"Ok, seriously. Work is work and after that, all bets are off." Nick leaned over and kissed her on the cheek.

"So where do we get these mopeds?" Sara looked at him inquisitively changing the subject for the time being.

Nick looked mischievous. "We could always stop by and ask Ned." A stolen moped was the very reason they'd met Ned in the first place.

Sara chuckled and nudged Nick in the ribs with her elbow. "Let's just ask him." She pointed to the man that they'd made their reservations with.

After a bit of confusing directions, heavy on the hand gestures, Nick and Sara finally found a place to rent mopeds. They made a quick detour to a pharmacy to pick up a few things, and Sara had to laugh at just how much Nick felt was necessary for the few remaining days they had left before they headed home. Once that task was complete, they did a leisurely exploration of the island, thankful that they'd thought to pick up a couple of disposable cameras to capture a few memories of their trip on. They followed the highway north until they came to Parque Punta Sur, a national wildlife refuge. They parked the mopeds and walked through the park coming upon El Caracol, an ancient Mayan lighthouse which was thought to be used as an early warning system for hurricanes. They spent a couple of hours exploring the park and taking in the history before they decided to head back to San Miguel and find something to eat for dinner.

Sara glanced over at Nick as they walked hand in hand to where they'd parked the mopeds. "I'm not sure I'm ready to go back to Vegas. I'm having too much fun with you."

Nick smiled. "There's nothing that says we can't have fun in Vegas." He squeezed her hand.

"That's not what I meant." She had a furrowed brow as she turned to face him. "I just don't have to share you with anyone here. When we get back, we'll have work and our friends..." Her voice trailed off as she watched him watch her.

Nick slid his arms around her waist. "I know. I'm not sure if I want to share you either." He leaned down and kissed her deeply, the mopeds momentarily forgotten.

Sara had a look on her face that Nick couldn't quite place when they broke the kiss. "Nick." She was feeling incredibly vulnerable and she knew that she was going to have to tell Nick about her family.

"Yeah?" He simply smiled, not wanting to show his own insecurity that her expression was producing inside of him.

Sara smiled. She didn't want to have this conversation here. As much as she wanted to tell him what was on her mind, she wasn't sure how he was going to react and so she reasoned that perhaps they should wait until they'd gotten back to the hotel. She leaned up and kissed him briefly, looking into his eyes as she pulled back. "I love you."

He grinned and let out a chuckle of relief. "I love you too."

They took their time getting back to San Miguel and they were both hungry by the time they returned the mopeds. After a quick stop for fish tacos on the boardwalk, something that seemed to have turned into a regular habit since they'd arrived in Cozumel, they walked back to their hotel to change their clothes and head out to get a real meal and maybe go dancing.

Nick was trying to decide between two shirts when he felt Sara's hand on his shoulder. He glanced up and smiled at her until he noticed the same expression on her face that he'd seen earlier. He immediately furrowed his brow. "Hey, what's wrong?"

Sara nibbled her lower lip nervously and just cut to the chase. "There's something that I really need to tell you. Something that I, well something that only my counselor and Grissom know, and..." There was a slight hitch in her voice as she noticed concern flicker across Nick's face.

"Whatever it is, you can tell me." A myriad of thoughts flashed through Nick's mind as to what big secret she had that she was afraid to tell him. He felt immediately protective of her and wrapped his arms around her.

Sara chuckled nervously even as she sniffled a little. "Can we just sit down?" She wasn't sure she was going to be able to get it all out if he held her like this. She wanted to tell him and then if he still wanted her, then she'd let him hold her; she'd need him to hold her. The memories had never stopped being painful.

They made their way over to the bed and Sara held onto Nick's hand as she curled herself up a little protectively as she reclined against the head board. She looked so small and vulnerable that suddenly Nick felt a rush of anger towards whoever had done something to her to make her so fearful.

"Sara, you can trust me." He looked at her intently.

Sara just nodded and took a deep breath as she began to tell him about what her life was like growing up in Tamales Bay culminating in the day her mother had killed her father and the subsequent shuffling around in the foster system until she'd gone off to Harvard.

As she talked, trying to keep her emotions at bay, Nick's expression moved from shock to hurt and then love for her as tears streamed down his face. When she finished, he pulled her into his arms and just held her, whispering to her how much he loved her. As much as he hurt for her, he also felt a strange sense of relief. He knew that she knew what it was like to be a victim, and for the first time since he'd met her, he decided he needed to garner the courage to tell her his secret too.
