"Hi Zoe!" Kaylee chirped, narrowly avoiding colliding with the older woman's swollen belly in the small stairway between the common area and the cargo bay. "All done with your checkup?"

"He's all yours, honey." Zoe smiled, knowing that the little mechanic was looking for her man.

"How's the new crew member?" Kaylee asked.

"Active." Zoe sighed. "Here." She took Kaylee's hand and placed it on her stomach. Kaylee and River both loved feeling the baby kick, and Zoe didn't mind at all.

"Ooh, he's jumpy today." Kaylee giggled. "He's anxious to get outta there, I bet."

Zoe chuckled. "He ain't the only one."

Laughing, Kaylee practically skipped down the steps and through the common area, stopping right in the doorway to the infirmary. "Hey sweetie."

"Hi there." Simon immediately got up from the stool next to the counter to give her a kiss.

"What's that?" Kaylee asked, gesturing to the sheet of paper in Simon's hand.

"The latest ultrasound picture." Simon explained. "See, there's his head, his arms, his...parts."

Kaylee snickered and swatted him on the arm. "I still can't quite believe there's gonna be a critter running around here."

"You can't believe it?" Simon grinned. "Before you came to breakfast this morning, Zoe said something to the captain about baby-proofing the ship. For a second, I honestly thought he was going to have a heart attack."

"Just think how he'll react when we start having kids in a year or two." Kaylee said.

"Two?" Simon repeated. "You'd really want to wait that long to have a baby?"

"Well, maybe not two years." Kaylee admitted, her heart fluttering at the thought of Simon holding a tiny version of himself. "But like I've said, I kinda want ya all to myself for a while. Maybe just a year."

"A year sounds good." Simon agreed, overwhelmed for a moment as he imagined how beautiful Kaylee would look with his child growing inside her. "How many kids do you see us having?"

Kaylee thought for a moment. "I always wanted a big family, but not too big...maybe three or four?"

Simon's eyes lit up. "When I was a kid, River and I always pestered our parents for one more brother and one more sister. Four sounds perfect."

"Well, perfect wasn't always the word I'd use to describe havin' three big brothers. But it was fun." Kaylee said. "So, four little Tams?"

"With your beautiful smile." Simon added.

"And your pretty eyes." Kaylee sighed happily.

"And your way with words." Simon joked.

"Let's hope." Kaylee giggled, kissing him when he pouted playfully. "I'm glad you're okay with waiting."

"Well, I kind of want you all to myself, too." Simon grinned, kissing her back.

"Sounds good." Kaylee murmured against his lips.

River leaned in and giggled, startling the couple.

"What's so funny, sweetie?" Kaylee asked, stepping back from Simon a little.

"Don't worry about it." River snickered. "Come on, don't want to be late for dinner." She scurried off, still laughing.

Simon glanced at Kaylee, raising one eyebrow. "Is it a bad sign that I'm sometimes a bit afraid of my little sister?"

"No, baobei." Kaylee said. "I think that's healthy.
