A/N: And now, Parker finally finds out if he's going to have a little brother or sister. Hope you enjoy! -AnaG

The man holds the little boy's hand, measuring his stride so that the boy does not have to struggle to keep up. When they reach the wide, clear window of the nursery, they stop and the man kneels down in front of his son. Smiling, he brushes the curls from the boy's forehead as he talks, his eyes never leaving his son's face. The boy leans forward, pressing the side of his face against his father's chest as he hugs him tightly. Placing a hand at his son's back, the man feels the tears welling in his eyes. After a moment, the boy moves back and points up towards the window.

Booth lifts Parker up, holding him on his hip, so that he can see into the room. It seems that there are rows upon rows of babies sleeping and crying in their hospital issued bassinets. There is only one though that captures his attention. There, front row center, wrapped in pink, is his little girl, arms waving, with what he swears is a smile on her face.

"Look…right there. There she is, Parker. Your baby sister, C.J.….Isn't she beautiful?"

Parker stares at the infant, seemingly entranced. Booth waits, knowing that his son is taking time to process the idea that baby is finally here….no longer just an idea, or something 'growin' in Bones' tummy.

Finally, the little boy seems to have reached an understanding. Nodding his head, he answers his father in a quiet tone.

"Mmm-hmmm. But she sure is small, Daddy."

"Yes, she is a tiny thing right now….but, you know, you were that little once, too."

Parker leans back, looking at his father. "Really? I don't 'member that. Glad I'm growin' up now." He turns back to look through the window at his little sister, thinking again.

"Daddy…whadja say that C.J. is for again?"

"Celia Joy…"

"Cee-lee-ya" The little boy sounds out the name, as if trying it on for size, then giggles.

"Daddy…that sounds like your name."

"That's right…that was Bones' idea"

"Yep…she does have good ideas." Parker nods, but then a small crease forms on his forehead.

" But Daddy….who is Joy? That doesn't sound like Bones' other name…"

"Well, buddy, Joy is…Joy is someone that Bones used to….know…a long time ago."

"Oh, okay…" The little boy's reply is muted, his attention already back on C.J. His face brightens, and he waves at the window.

He turns to his father, excitement in his eyes. "Look, Daddy…she's waving at me. She knows I'm her big brother! Its cause I read her all those stories, I bet…"

"I'm sure she does…So, little man…you're not too disappointed that you didn't get a little brother?"

"I kinda was sad when you first tole me, but then I 'cided somethin'"

"And, what did you decide, buddy?"

"Weellll….Bones is her mommy….and Bones is a girl."

"Mm-hmm"

"And Bones is pretty cool for a girl. So, all we gotta do is…me 'n Bones will teach her about the good stuff like pirates, and frogs, and diggin' in the dirt and…"

The woman sits on the sofa with a quiet sigh, placing the baby monitor on the table in front of her. She places a hand on the pile of freshly laundered baby clothes next to her, intent on folding them…but the now novel idea of just being still and doing nothing…even if just a for short while… is too appealing. She leans back, and her eyes drift slowly shut.

She jerks awake suddenly, instinctively looking towards the monitor. Hearing silence, she lets out a sigh of relief. Without looking, she starts to reach for an item to fold, but her hand finds nothing but the upholstery of the sofa. Glancing down, she sees her hand resting near a stack of unevenly folded onesies and sleepers. A sleeve hangs down from the middle, and the entire stack leans precariously to the left, but to her, it couldn't be more perfect.

"Babies sure are a lot of hard work, aren't they, Bones?"

She looks over and finds Parker seated at the other end of the sofa, holding a white sleeper dotted with little dancing ducks.

"Yes, they certainly can be. Lucky for me, I have my partner here to help me out."

Parker places the last item of clothing on the stack with a small pat. "Un-huh, cause I'm the big brother."

"And you are a very good big brother. CJ is a lucky little girl."

"Cause I'm her brother?"

"Absolutely…." As she speaks, she moves the stack of clothes to the table, pats the sofa cushion next to her. After Parker slides over, she places an arm around his shoulder, hugging him closer to her.

"You know….I can tell CJ loves you already. When she hears you talking, she starts waving her little arms in the air."

"Really?..."

"Mmm-hmm. Big brothers are very special to their little sisters, right from the beginning…." She pauses, a flash of memory crossing her mind.

Sensing that something has changed in her tone, Parker looks up at her, concern in his eyes.

"Are you sad now, Bones?"

Realizing that she has drifted off into her own memories of big-brother hero worship, she shakes her head, quickly hiding the sadness behind a smile.

"No, Parker. Don't worry…I'm not sad. I just thinking about…Did you know that I was a little sister once?"

"You were?"

"I certainly was…and…you will like this, Special Agent Parker….my brother and I, we had a special secret code, just for the two of us. Do you want to know what it is?"

"You can tell me? Even if itsa secret?"

She pretends to ponder his question for a moment, then nods her head. "Well…you are a big brother now, so I think it will be okay if I tell you….

Parker listens intently as she begins to tell him the story of the "secret code", his eyes never leaving her face.

A door creeps back slowly, and the little boy's head peeks through the opening. Once he's sure that the coast is clear, he steps out of the room. Staying close to the wall, he tip-toes with exaggerated care down the hallway, pausing once when he hears a noise from the next room. When he reaches the next door, he slowly turns the doorknob and pushes open the door. Stopping one more time to make sure that he hasn't made enough noise to alert the adults, he slips silently into the room.

Unable to sleep despite her exhaustion, she rests on her side, staring at the baby monitor on the nightstand. When she sees the red light begin to flash, she starts to sit up, but stops when she hears the voice coming from the speaker.

"Marco…"

There is a short pause before he continues. "And then, CJ, you say…Polo. You can't say it right now 'cause you're too little. But when you get bigger, if I say Marco…that means that I'm tellin' you that I love you. Then you say Polo and that means…."

She sits in the dark listening to Parker whisper to his baby sister, smiling even as she is wiping away her tears.

Oh, Celia Joy…you are a lucky, lucky little girl.

This is the final chapter in the adventures of Special Agent Parker. Thank you all again for the reviews and encouraging words along the way. And for those that might be interested, there is a third in this series, one that features a little girl named Celia Joy, affectionately known as Cee Cee, that I will begin posting soon. I hope you will enjoy her adventures as much as S.A. Parker's! -AnaG
