Chapter 18: Meeting Katie

November 3, 2016

When the group made it to the correct floor, and since there was too many people to go in there all at once, they decided to take turns. And with Catherine and Warrick knowing them the longest, it was only fair if they went first, but of course they weren't going in the room empty handed, so while Rick was going to stay out in the hall with the rest of the family, Isabella was in Catherine's arms and Warrick was holding on to William's hand as Warrick knocked on the door with his free hand.

A second later they hear a come in from Sara, so Warrick opens the door as Grissom stood up from sitting on the bed, and the minute William saw his mother, he rushed to her side while he quietly shouted, remembering to use an inside voice. "Mommy!"

With Katie in Sara's arms, she smiled with tears in her eyes as she saw her oldest child running towards her. "Hi baby."

When he got close to the bed, Grissom picked him up, but before he sits him down, he whispered. "You remember what we talked about?"

William nodded. "Be careful when mommy has the baby."

"Good job."

Once William was on the bed, he moved as close, and carefully, as he could to his mother before they shared a kiss, then Sara smiled as she said. "Baby, I would like you to meet your baby sister, Katie."

William looked down at the baby in his mother's arms, and even though he secretly hoped he would get a brother, one look at her, he knew she was meant to be in this family, she made the family complete, so he smiled and reached for her hand, laughing as he exclaimed. "Her hands are so tiny."

They all chuckled while Grissom spoke, who now had Isabella in his arms. "So was yours, buddy." Then he kissed Isabella's cheek as he whispered. "And yours too, butterfly." Making Isabella giggle as his stubble tickled her.

William cleared his throat and said softly. "Hi Katie, I'm your big brother, and I promise you I'll be the best big brother I can be." He looked at his mother with tears in his eyes. "How was that?"

Sara sniffled as she replied. "That was beautiful, and you remember what we talked about?"

He nodded. "Just because we have a new baby in the family doesn't mean you love me and Izzy any less."

"Yes, the love I have for you three will always be there, no matter what."

"I love you too mommy." He then turned around and smiled at his other sister. "Izzy come meet our baby sister."
Grissom walked closer to the bed and sets her down, and before Grissom could speak to her, William spoke in a comforting, yet, warning tone. "Izzy, this is Katie, and she is just a baby so you have to be careful."

Sara and Grissom shared a loving look while Isabella spoke while looking at the baby in her mother's arms. "Baby? Mine."

They all chuckled before Grissom placed a hand on her back before replying. "She's all of ours, butterfly. But you get to be the big sister, can you say Hi to her?"

Isabella smiled as she waved at the baby. "Hi." When the baby wasn't waving back, Isabella frowned. "Not waving."

Grissom picks his daughter back up and kissed her cheek before smiling. "That's because she's only a few hours old, she'll wave when she gets older. Ok?" Isabella just nodded with a smile before Grissom continued while he addressed William too. "And now that she's here, I need you two to look after her, protect her, be the older siblings I know you can be."

Isabella just nodded while William, who already took his big brother role serious with Isabella, nodded with a smile. "You can count on me daddy."

Grissom smiled with a nod. "Thank you buddy."

As William nodded in return, Grissom stepped to the side while Sara cleared her throat and looked over toward Warrick and Catherine. "Hi you guys, come meet the newest Grissom member, Katie Grissom."

Catherine and Warrick walked towards the bed, and once they were close enough, Sara transferred her youngest into Catherine's arms, which at first Katie started to whimper, but Catherine being a natural, soothed her pretty quickly before looking down at the little girl who had capture everybody's hearts already, and she took a breath as she spoke after studying her. "Wow, I see a lot of Grissom in her already."

Sara, who was now holding William in her arms, nodded with a smile. "I know, amazing, isn't it?"

Catherine nodded with tears in her eyes, so proud of the man she had called best friend for years, and when Grissom saw the tears in her eyes, he walked up to her and said softly. "Catherine it's ok."

Warrick wrapped an arm around his wife as she shook her head with a smile. "I'm just really proud and happy for you." She then looked at Sara with a smile. "Both of you." She then sniffled as she shook her head. "Besides, you know how I can get with babies."

They all smiled before Grissom smirked. "Well, I'm sure it won't be long for you to be around another one."

She smirked in return while handing Katie to her husband. "If that is a crack about me becoming a grandma, then bring it on." After they chuckled, Catherine stepped up to Grissom and gave him a hug. "Congratulations, I'm honored that I get to be apart of this, seeing you become the father I knew you could be."

He cleared his throat as he placed his free arm around her and whispered. "Thank you, Catherine."

She nodded as they pulled back, then after taking a breath she had a moment with Sara, happy their friendship was a lot more solid than it was when they first met.

After a few minutes, there was another knock on the door, and once Sara said come in, Carly, Brett and Andrew walked in, which Isabella shouted with a smile, even though it wasn't that long since they saw one another. "'drew!"

Everybody chuckled, and after Warrick handed Katie off to Carly, he walked over to Sara and had a moment with her before congratulating Grissom, then him and Catherine left the room to give the Boldens their moment with the Grissoms, and while Sara had a few questions for Carly, she refrained from asking at this time, wanting this moment for her daughter to get as much attention as possible. And she did, not only from the rest of the team, but from Ryan, Andrea, the other Bolden 'Children' and Kyle, which Sara and Grissom witnessed a longing look between Kyle and Lindsey while Kyle was holding the little girl in her arms, only confirming Grissom's thought of Catherine becoming a grandma soon.

Once everybody had their moment with the newest, youngest member of the family, and since Isabella wanted to go with Andrew, it was back to being Sara, Grissom, Katie, and William, who wanted to stay with his parents and baby sister, in the room.

Grissom sighed as he sat up on the bed with Katie in his arms while William was in his mother's, then he looked over at his wife and son and smiled. "Well, our Katie was definitely a big hit."

Sara nodded with a smile. "Yeah she was."

William asked with a hopeful look. "Was I?"

They chuckled before Sara hugged him a little tighter with a sigh. "Are you kidding, you were, are, our biggest hit. In fact, to many of the family members, you were the hit that they thought would never happen."

He frowned as he asked. "Why not?"

Grissom took that response. "For a lot of grown up reasons, ones we'll share with you when you get older."

As he nodded in understanding, Sara kissed the top of his head and whispered. "But know you were always wanted and you're our little miracle, you taught us how to be parents, you opened our hearts bigger than we ever thought possible, you showed us what unconditional love truly is."

Feeling a little emotional from his mother's words, William asked softly. "Wow, I did all of that?"

Grissom nodded with tears in his eyes. "Yes you did, buddy, we love you so much, so thank you for being our son, for letting us share our hearts with your sisters."

William eyes started to fill up with tears as he whispered. "You're welcome, daddy. I love you too."

Sara kissed her son's head again while closing her eyes with tears in them, and after a moment, she took a breath before asking him about the trip he had with his father.

While he was basically giving her the play-by-play about the trip, which Sara was hanging on to every word, Grissom looked down at his youngest daughter/child in his arms and smiled, three beautiful children with his amazing wife, life at this moment couldn't get much better. How he got this lucky he'll never fully know, or understand, but he'll cherish every moment he has with them all.

AN: I Hope you enjoyed it. More to come soon.
