Joss Whedon fully owns Simon, Mal, Inara, Zoë, River, Jayne and Kaylee; I am only borrowing them for this story. None of my knowledge of what it's like to be pregnant is firsthand, so I apologize if it seems unrealistic. Also, I have no idea what a Hydraulic Pin is.
Mozart And Bach
Kaylee loved Simon. She had always had a crush on him but now that he had reciprocated, she loved him more than ever. They still had their disagreements, but she was happier than ever.
It was about three weeks after Zoë had announced her pregnancy. Kaylee was in the engine that morning room, fitting some new parts, when she fainted.
She woke up in the infirmary with Simon standing over her and Jayne walking out the door. Jayne had stayed until he knew she was going to be ok and then left quickly.
She smiled up at Simon and he smiled back at her, though his smile was rather fixed.
She frowned. "What happened?"
He turned away to wash his hands. They weren't dirty but he felt like he had to do something. He replied, "You passed out."
She stood up. She felt kind of dizzy and closed her eyes for a second. He noticed this and grabbed her. After a moment, she felt better. She laughed. " I gotta get back to Serenity. I'm shiny now, honest."
"Wait," he said, "there's something I need to tell you."
She frowned, "good news or bad news."
Simon thought for a moment "Medically it's neutral, but I think you'll be pleased." As he said this, he knew she would be.
She cocked her head and looked at him. He took a deep breath. "You're pregnant."
Her face lit up in a huge grin when she heard this. She hugged Simon and he looked surprised. She looked at him. "Ain't you happy to be a dad?"
He smiled "I am but,"
She looked hurt. He quickly tried to explain, "I'm just nervous, I've never been a father before, and I…"
She giggled. "Simon, you'll do great," He smiled a t that. She headed for the door "I'm going to tell everybody."
"Wait," he said for the second time. She turned. He looked down. "I know we'll have to tell the crew sometime, but I was hoping it might be, you know, 'our little secret' for a while." He looked up. "Plus it would be better to conserve your energy and wait until everyone's, gathered, like at dinner."
She smiled and glanced at the clock. It said 10:30. "Lunch is in a couple a hours, I'll wait 'till then."
He sighed melodramatically "A few hours of secrecy will have to be enough then," Kaylee giggled then said "I have to get back to Serenity. She needs me."
"Okay," he said "but be careful."
She smiled, "I will."
An hour and a half later, they both headed to lunch. Kaylee was exited to announce her pregnancy, but Simon was more nervous about the captain's reaction. He knew the captain had taken Zoë's declaration well, but a second so soon might not be the best. He sighed. Kaylee wanted to tell everybody, but Simon knew she especially wanted the captain to know. He hoped her faith was well placed.
Everyone sat down at the table. The meal had just begun when the captain said, "We got a job." While, Jayne and Zoë seemed exited Kaylee's face fell. Inara was the first to notice.
"What's wrong mei, mei?" She asked concernedly.
"Oh, nothing I guess, I just wanted to tell everybody and now we got a job and,"
The captain cut in "If you need to tell somthin' tell it"
Kaylee looked up and said "Captain, everybody, I'm pregnant."
Jayne grinned like he did when he talked about guns and whores. Zoë Just smiled "I'm not the only one now."
Inara, who was sitting right next to Kaylee, just hugged her tightly.
Mal turned to Simon, who had been watching the proceedings silently. "I conjure you're the father?" Simon nodded. "Congratulations." Simon smiled. He was glad the captain wasn't taking the news badly.
It had eight and a half months since Kaylee made the announcement, and she and River were sitting in Inara's shuttle having tea. River suddenly said, "They want to come out now."
Inara looked puzzled and Kaylee asked "Who?"
River rolled her eyes "You think there's only one but there are two and they'll come out in three days"
Kaylee turned to Inara, and Inara smiled. "She says that you'll give birth to twins in three days."
Kaylee gasped. "Twins?"
River smiled "Look more like each other than they do themselves and can read each other," River smiled. "Just like you got 'sept yours are not the same."
Inara went pale, and Kaylee asked, "Are you okay?"
Inara quickly regained her composer and nodded "Of course"
It came to pass just as River said it would. Three days later Malcolm and Jayne had left for a job. Zoë and Lillian were resting in Zoë's Quarters and Simon was preparing the infirmary in case Mal or Jayne was hurt.
Kaylee was with Serenity's engine when River approached her "You must come at once to see my brother."
Kaylee shook her head. "I gotta finish installin' this hydraulic pin first."
River looked annoyed, "No you must come with me right now."
Kaylee slotted the Pin into place and turned to face River "River," she began.
River interrupted her by practically screaming "Now!" Kaylee was tired and gave in. They walked to the infirmary together. When they got there they met Simon. River merely told him "They want to come out now."
Simon was trying to figure out what she meant when Kaylee let out a gasp of pain. Simon grabbed her and carried her the rest of the way to the table. River followed him.
The delivery took 12-hours. Inara held Kaylee's hand the whole time and river sat on the other bed and watched as Kaylee pushed. About 11 and a half hours into labor the first baby was born. Simon cleaned him up and turned to tell Kaylee it was a boy but just then she screamed as another contraction hit. Simon handed the baby to River and bent to check on Kaylee. He was surprised to see another head. He let forth a string of Chinese cruses.
Inara looked at him. "What's happening?" She asked, using all her training to keep the panic from her voice.
Simon took a deep breath and replied "twins."
Inara relaxed a little because she knew her friend was in no danger.
Once the second baby was born, Simon made sure to wrap him in a different colored blanket then the first. Kaylee was panting from the strain, but when simon handed her son to her she smiled with delight. Simon asked her "What should we call them?"
Kaylee was tired but she thought for a moment, "What were those earth that was musicians your parents made you and river listen to?"
Simon frowned. "you mean Mozart and Bach?"
Kaylee nodded "Exactly we'll call him," she indicated the first twin who was still in Rivers arms, "Mozart, and we can call you," She said, addressing the child in her own arms "Bach."
"Bach Lee because lee is your middle name."
River smiled down at Mozart "Then he will have to be Mozart James because James is your middle name Simon."
Simon looked down at Kaylee. She smiled tiredly and said "James is a nice name."
Simon smiled "Mozart James and Bach Lee they are."
Kaylee added "Tam don't forget their both Tams."
