On Saturday morning, Booth's sitting on the living room rug with Christine sitting between his legs. He's running a brush through her silky auburn hair and listening to her sing "Twinkle Twinkle Little Star" over and over again. He smiles.

Christine jerks her head forward and yelsp. "Ouch, daddy."

"Sorry, princess. I'll try and be gentler. Just keep still for me, please."

Christine nods. "Oops."

He laughs and slides his fingers through his daughter's hair, attempting to carefully untangle the knots before taking a brush to her beautiful waves.

"Do you like my dress, daddy?" She asks, tugging on the deep purple dress and knocking her feet, which are tucked into black ballet flats, together.

He nods. "It's very pretty, baby." He pauses. "Keep still please. If you keep moving, you might end up bald."

She giggles. "No way."

"Yes way." He sets the brush to the side and smiles. "I'm gonna try my best to braid your hair like mommy does, but she'll probably have to redo it for ya when she gets out of the shower." He pauses. "Keep really still for me, princess."

"Okay, daddy. I'm like a ice cube."

He continues to listen to her sing as he braids her hair. "Hair-tie."

She takes the black hair-tie off her wrist and hands it to him.

"Thank you, princess." He ties her hair and gives her braided ponytail a tug. "You're all set."

"Is my hair pretty, daddy?"

"The braids aren't as neat as when your mommy does it, but yeah, baby, your hair is very pretty."

Christine hops up and twirls, the skirt of her dress lifting up in the air.

He takes her hand and lets her spin around. "That's my beautiful baby girl."

"I'm not a baby." She pouts.

"No, you're not, but you'll always be my baby girl, even when you're thirty."

Christine giggles. "And you'll always be my daddy."

"Always." He pauses. "Stand on my feet, princess. Let's dance."

She steps onto his feet carefully and takes his hands.

Booth and Christine move around the living room, the little girl smiling and giggling.

Brennan walks down the stairs and stops right when she enters the living room. She smiles, and the longer she stands there, staring, she feels tears tickle her cheeks. She wants to blame them on her raging hormones, but she knows they have nothing to do with her sudden onset of emotion. She quickly wipes the tears away and clears her throat.

Booth stops dancing and turns his head, smiling at his wife. Wife. He still has to pinch himself whenever he says or even just thinks about it. "You look nice."

"Just nice?" Brennan questions with a slight smirk as she adjusts the straps on her dress.

"You look beautiful, Bones, but you always look beautiful."

"This dress is okay?"

He nudges Christine off his feet and walks over to Brennan. He takes her hand and slips his fingers between hers as he presses a kiss to her lips. "I love when you wear blue. I've told you that before. The dress is perfect." He kisses her again.

"Ew! Stop it. Stop it right now." Christine pushes her parents apart and wedges between them.

He laughs and scoops her up, giving the little girl a kiss on the cheek. "Is it gross when I kiss you?"

Christine shakes her head. "No."

"Why not?"

"'Cause you don't eat my face like you do when you kiss mommy, daddy."

He bites his bottom lip and looks at Brennan. "That's enough, princess." He sets her down and smiles. "Doesn't mommy look beautiful?"

Christine nods, looking up at her mother. "Yep. Do I look pretty too, mommy?"

Brennan nods. "Yes, Honey. You look very beautiful."

"Daddy braided my hair."

"Turn around for me so I can see."

Christine twirls around.

"Slowly, Christine, I mean turn around slowly."

"Oh." Christine slows her twirling.

"Your daddy did a great job. I'm surprised." Brennan glances at Booth and smiles. "You've been practicing or watching me very closely. Either way, the braid looks great. It's a little messy, but it'll just come out anyway while she's running around with Michael Vincent at the party."

He nods. "Thanks, Bones. I tried." He pauses. "Are we still keeping, you know what, a secret?"

"Keeping what a secret, Booth?"

"You know?"

Brennan shakes her head. "You're going to have to be more specific."

"The baby," he tries and fails to whisper.

Christine tugs on her father's jeans. "What baby, daddy?"

He freezes, swallowing and turning his head down slowly to look at his daughter. "Your Auntie Angela's having a baby and it's a big secret."

Christine's eyes widen. "Really?"

Brennan slaps Booth on the arm. "Booth, that was not our secret to tell."

"I had to think of something fast, Bones. What did you want me to tell her?" He whispers.

Christine looks at her mother. "Mommy, when are you gonna have a baby like Auntie Angela?"

Brennan glares at Booth. "Thanks a lot, Booth."

He shrugs.

"Soon," Brennan answers. It's not really a lie.

"What's soon? Like today? Tomorrow? A month?"

Brennan continues to glare at Booth, squeezing his hand tighter.

He yelps. "Ouch, Bones, not so tight," he whispers through gritted teeth.

Brennan doesn't let up. "This is your fault."

"My fault? If you just understood what 'you know what' meant, then I wouldn't have had to say baby in the first place, so this is your fault."

"Well, excuse me for not understanding your ambiguity. I apologize." Brennan pauses. "You brought it up, so this is your fault."

Christine sighs. "Mommy, daddy, don't fight please. I don't like it when you guys fight. It makes me sad."

Brennan sighs.

He shakes his head. "We're not fighting, princess. We're having a disagreement." He smiles at Brennan and gives her a soft peck on the lips. "See? We made up."

Christine nods. "Uh-huh." She pauses. "I'm hungry."

He lets out a breath, grateful for his daughter's pea-sized attention span.

Brennan nods. "How about I slice an apple for you, Honey? We're going to be eating a lot of food later, so I don't want you to eat too much now. Otherwise, you won't be hungry."

Christine nods. "Okay, mommy. Peanut butter too?"

Brennan nods. "Peanut butter is a good source of protein, so a little bit of peanut butter will be fine." She takes her daughter's hand and they head into the kitchen. She turns her head and looks at Booth. "Consider yourself a lucky man, Mr. Booth."

He swallows, smirking at her. "Oh, I am a very lucky man, Mrs. Booth." He laughs. "I'm gonna go check on Parker. He's supposed to be getting dressed."

Brennan nods. "Today's a big day, Booth. He's saying goodbye to his mother. Go and check on him." She pauses. "And don't call me Mrs. Booth."

He flashes her a smile before heading up the steps.

"Let's go get you a snack, sweetheart."

Christine nods. "Why'd daddy call you Mrs. Booth, mommy?"

"Your daddy's trying to be humorous."

"My name is Christine Booth." The five year-old beams.

Brennan nods. "Yes it is, Honey."

"Daddy is Mr. Booth. You said so just now."

Brennan nods again. "Yes, Honey, that is also correct."

"Jenna's mommy and daddy are Mr. and Mrs. Marshall. They're married, so they're both called Marshall."

Brennan nods.

"Are you and daddy married? He called you Mrs. Booth and you called him Mr. Booth."

Brennan gives her daughter yet another nod. "Yes, Honey. You were there, remember?"

Christine smiles. "Oh, yeah." She giggles.

Brennan grips her daughter's hand a little tighter. "Come on."

Christine skips into the kitchen, holding her mother's hand, still smiling.
