Chapter 1: The start of another day

May 15, 2015

Laying in the comfort of their bed, Grissom pulls back from the passionate kiss he had been sharing with his wife, and Sara took a breath before smiling as she cupped his bearded cheek. "Well, good morning to you too, Dr. Grissom. You must of woken up on the right side of the bed."

Grissom smiled with his blue eyes sparkling. "How can I not when I get to wake up next to the most beautiful woman in the world." Even though she's been hearing him say those words for well over ten years now, it still made her feel a little shy hearing it, so she smiled shyly as he chuckled slightly and continued with love in his eyes. "You can get shy all you want, I'll never think otherwise or tell you any differently, no matter how much time has passed us by."

She moves her body upwards so she could move her head closer to her husband's as she whispers. "I believe you, and that's what makes me feel like the luckiest woman in the world."

Before he could speak, her lips were on his for a kiss, which got to be pretty passionate rather quickly as they moved so she was now on top of him. She pulls back slowly after a few moments and opened her eyes, which as their eyes connected, the desire/love was shown.

He moved his hand up to her cheek, ran his thumb up and down it with a smile on his face, saying the words with his eyes, she smiled in return, saying the same words back before pressing her lips to his again, getting lost in the moment, knowing they still had time before they had to get ready for the day.

"Warrick!"

Catherine gasps as she sits up in bed with a start, and a second later, jumps when she feels a hand land on her shoulder.

"Babe, it's me."

She nodded as she turned her head to look at her husband, then a moment later, he wraps his arms around her and brings her close, which she held on to him tight right away, wanting to hear his steady heartbeat in her ear as hers raced from the nightmare she had just woken up from.

Once they were both settled, he kissed the top of her head and whispered. "How did it happen this time?"

Still trying to calm her racing heart, she took a breath and replied softly. "A car accident."

About four years after Warrick left Vegas to follow her to Miami, and around this time of the month, she had gotten nightmares that something bad happened to him. Not that she didn't get nightmares any other time, after all of what she sees in her job, even if her time out in field is limited these days, but these nightmares seem more vivid than others.

He frowned a little. "That's a first, usually I'm at a crime scene when it happens."

Taking another deep breath, she nods as she pulls back from his arms a little so she could look into her husband's eyes. "I know."

Knowing the look she was giving him, he gives her a small smile as he moved one of his arms from around her and cupped her cheek. "I know that look babe, but you know I have to go in today, with Carly and Brett up in Seattle and Luke not back from his vacation until tomorrow, it would be unfair to call someone else in without notice."

In the past, to make it easy on Catherine after she had one of those nightmares, Warrick would take a few days off, and it was going to be a plan this year too, but just yesterday Carly's mom ended up in the hospital, so obviously she and Brett left for Seattle immediately.

Catherine nodded sadly. "I know, I just..."

She trails off as she looks down, and he moves his thumb towards her chin and lifted her head back up and gave her another smile. "I'll tell you what, I'll call Sara and see if she can give me a ride into work this morning, and I'll make sure I work with her today. I won't leave her sight."

He figured if there was anybody in that lab, or any lab for that matter, that she would trust more, outside of herself, to keep him safe, it was Sara.

She smiled as she asked. "Really?"

He nodded with a slightly bigger smile in return. "Really, nobody would mess with Sara."

She chuckled slightly, feeling a little more relieved as she gets back into his arms. "Thank you." Then feeling a little embarrassed, she whispered. "You must think that I'm..."

He cuts her off as he held her tight while he moved them down so they were laying back on their mattress. "Hey, you know what, I would probably feel the same way." He kisses her head before he continued. "In fact, I do feel the same way when I have bad dreams too and it involves you."

She moved her hand to she could place it on his bare chest and whispered. "You do?"

"Of course, I just don't tell you because I don't want to worry you more than you already do." She kissed his chest this time as he continued while running his hand up and her arm. "And I promise you this, I'm not going anywhere. I have a bright future to look forward to, like walking two beautiful daughters down the aisle on their wedding day, watching my sons grow into men that I can be proud of."

Catherine smiled, thinking of the same future, as she added. "And grandchildren?"

He chuckled with a nod. "Eventually yes, but let's hold off on that dream for awhile, ok?"

She chuckled in return. "I agree."

Feeling emotional, he finished. "And you know what else?" She pulls back slightly so she could look into her man's eyes as he cupped her cheek. "Anniversaries with you, I want as many as I can get, you hear me?" She nodded with tears in her eyes. "I'm not done with you, not by a long shot."

He wiped her tears away before bringing her back down so they could share a deep, passionate kiss, wanting to wipe her nightmare away, then after pulling back, she gets back into his arms and holds him tight as he whispered. "I love you."

One last sniffle, she whispered. "I love you too."

An hour later

While William was sitting at the kitchen table, and Isabella was in her highchair, Grissom was cooking as Sara, who was dressed for the day, walked into room with her phone up to her ear. "No problem, I'll meet you outside in 40 minutes? Ok, bye Warrick."

As she pulled the phone from her ear, Grissom turned to look at his wife with a raised eyebrow. "What was that about?"

She stuck her phone in her pocket and replied. "I guess Warrick is riding with me this morning."

While they thought it was interesting, it wasn't an uncommon request, even Sara had been known a few times since the Brown's moved across the street to ride with him to work, so they just chalked it down to 'one of those days' and shrugged their shoulders before Sara turned her attention to their children with a smile while Grissom turned his attention back to cooking their breakfast.

Eventually their plates/bowls and glasses were empty and in the sink, and after Sara said her loves yous and kissed her family goodbye, she grabbed her CSI items, keys, purse and a jacket before walking outside and closing the door behind her.

When she came in perfect view of the Brown residence she saw Warrick standing there with his backside against the front of Catherine's vehicle, who seemed to be deep in thought, so she smiled and said. "You ready?" When he didn't respond the first time, she shouted a little louder. "Hey Warrick, you ready?"

Mentally shaking his head at the sound of Sara's voice, he looked her way and nodded with a smile before heading towards her driveway.

Once they were in her vehicle and buckled up, Sara started it, the police scanner in a low volume also coming on, before backing out of the driveway, and they weren't down the street that far when Sara finally spoke, breaking the silence between them. "Is everything ok?"

Still feeling a little spaced out, Warrick mentally shook his head and asked. "Huh, What?"

Sara smiled as she repeated herself. "I asked if everything is ok, you seem a little off right now."

He cleared his throat before responding. "Oh, uh yeah, everything is fine." As convincing as he tried to be, she wasn't really buying it. She's known this man for a long time now, and knows when something is really off with him, which she was about to call him out, but he spoke again before she could. "Have you ever felt you missed out on something big when you left Vegas?"

She was a little surprised about the unexpected question at first, but then she chuckled and smiled before answering. "The biggest moments of my life happened after I left Vegas, what could I have missed that was bigger than getting married and having two children?"

He nodded with a smile. "I guess you got a point there."

Sara stopped at the first stop sign and looked over at her partner/friend before asking in a soft tone. "Is this about you missing time with Eli?"

She wasn't totally wrong about that question, he did still beat himself up for missing out on 9 years of his life, even though he never knew about him, and Sara could see in Warrick's eyes that the answer to her question was partially right, even if that's not exactly where his mind was currently at, so she continued. "I can only imagine how it must feel to have a child in your care after years of not knowing that he existed, but I also know the choice between leaving or staying isn't a simple one for you, because had you stayed, yes you more than likely would have known about Eli and had more time with him. But on the other hand, look what you could have missed out on. Would you still be married to Catherine? Would Cassandra exist? And what about Rick, where would his life be hadn't he been adopted by you two?" Warrick's heart raced at the thought of never having that life with Catherine as Sara continued with a comforting tone. "It's a situation I don't envy for sure, and I'm sorry if you're still torn about it and the circumstances that lead you to find out about him, but..."

He cuts her off with a slight smile. "But I should stop beating myself up about it, and thinking about all the 'could haves' or 'what if's' will only drive me crazy?"

She gives him a smile before replying. "I only say that with love and care."

Warrick nodded. "I know, and I get it." He sighed a little before continuing. "It's just hard sometimes not to, you know." Sara nodded in understanding as she placed a hand on his shoulder for comfort, then after a second she places her hand back on the steering wheel, looked both ways before starting to drive again, then he asked a question that shocked her. "Then how about I change the question, do you think leaving Vegas saved your life?"

Sara gasped, almost swerving the vehicle in the process before quickly gaining control of it again, and just as she was about to ask where this question came from, they hear from the police scanner that there was a break-in and assault at an apartment complex, which they were going to just let the cops take care of it, and they'll deal with it if it came to them later, but when they recognized the address to it being one of their own, albeit on another shift, there was little hesitation when Sara changed the direction of her vehicle.
