Sorry it's been awhile, I've been really sick.

Jayne woke with a grumble, and a familiar warm weight on his chest. As usual, Charlie was sprawled over him, her head resting on his pectorals. He pulled the blanket further up her back as she gave a shiver. But the shaking didn't stop, in fact it got worse.

He began to panic, and rolled them over so he was holding her increasingly thrashing body down. Seeing no end in sight, he leapt off the bed and hurriedly pulled on his pants. Jayne's face was a mass of concern as he scooped her up into his arms and headed for the infirmary.

He ran as fast as he could to the doctor's room next to the infirmary. "Doc! Doc get up. It's Charlie, something's wrong!"

Simon opened the door. "Jayne?" One look at Charlie's seizing form made him order, "Get her on the table and try to hold her still."

Jayne's panicked shouts woke up the rest of the crew, and made them rush to the infirmary. Mal walked in to find his half-naked merc half on top of the spasming transgenic, who was naked except for a blanket, and the doctor loading a syringe with a clear fluid.

As soon as Simon had injected Charlie with the substance, she stopped moving and her breathing fell into a more normal rhythm.

"What's wrong with her doc?" Mal asked, as Jayne backed away from Charlie.

"She's suffering from a serotonin deficiency." Simon said, putting away the syringe and bottle. "It's a control mechanism built into her by Manticore."

"Will she be alright?" Kaylee asked, rubbing her arms as she walked in.

"She will be." Simon looked down at Charlie's unconscious body. "I don't know about the baby though."

"Baby?" Mall asked, raising an eyebrow.

"She's pregnant?" Jayne whispered, drawing Mal's attention.

"Yes. I wasn't supposed to say anything until she decided what she's going to do." Simon shook his head, "Of course termination's only an option for another few weeks."

"No." Jayne burst out.

The captain turned to him. "What the hell is going on here Jayne? First you bring her in wrapped in a blanket, and you're shirtless. And now this."

Jayne turned pale. "Uh..."

"You gorram bastard!" Mal swung back, then punched Jayne so hard, he didn't have to look out a window to see stars.
