"Rose," the Doctor approached her anxiously and Rose was instantly worried.

"What? What is it?" She asked. "What's wrong with me?"

"Nothing's wrong," the Doctor said quietly taking her hand. "You were right, you are pregnant again."

"The baby's aright isn't it?" Rose said searching his face for any clue as to what was causing the pain.

"Yeah, but you've got to stop stressing," the Doctor said quietly. "You're stress is scaring the baby and it's growing at ten times the rate it should be, that's why you're in so much pain."

Rose looked at him as though he was mad but when she saw he wasn't joking she lay back down.

"Right," she said running a hand through her hair. "Why didn't this happen with Jack?"

"'Cause this time round you were worrying over your child and that's a powerful emotion to toy with," the Doctor said gently.

"So what do we do?" Rose asked, trying to calm herself and not worry about her Mum or Mickey too much. "Surely if it's growing at ten times the rate then… I'll be pregnant less than a month…"

"Yeah, well, if you stay calm the baby should slow down its growth," the Doctor said. "But I can't make any promises. The only thing I can do is stop the pain."

"Ok," Rose nodded. The Doctor wandered back to the computer in the infirmary and began to type at it again.

Rose sat up gingerly and pulled Jack into her arms. She hoped that the new baby might slow its growth if it could feel its sibling close by.

"There done," the Doctor said coming back over to her and kissing her.

"What did you do?" Rose asked.

"You know how I had sympathy pains when you gave birth to Jack?" The Doctor said, sitting next to her and wrapping an arm round her. Rose nodded. "Well, I just used the TARDIS to redirect the pain, so that I feel it instead of you."

"But I don't want you to suffer," Rose said looking up at him.

"It's alright," the Doctor shrugged. "I've suffered through worse and maybe the baby will feel safer if it has a connection to both its parents."

Rose nodded. It made sense.

"We'll go look for your mother and Mickey in a bit," the Doctor said. "You rest and then I'll start tracking their DNA patterns."

Jack thumped his head against the wall again and again. How could he have been so stupid? All that time he'd spent hoping the Doctor and Rose would come back for him and he hadn't thought about what he already had. No if he wasn't careful he was going to loose Charlie altogether.

Jack wasn't sure he could cope with that, not after everything they'd been through together. They'd had to work hard on their relationship and it probably hadn't been made any easier by Jack's fantasies.

He banged his head again and cursed when he really hurt himself. He sat on the bed sighing. He'd never felt like this about anyone before, how could he just leave Charlie now? It'd break both their hearts.

Charlie found the bathroom fairly easily and had a sneaking suspicion that the TARDIS may have helped. He'd read up about the Doctor's telepathic time ship on his mother's data files.

He smiled his thanks and locked the door behind him. He stared at his face in the mirror and wondered what he was going to do if Jack decided to go with the Doctor and Rose, which was more than likely. He'd be back to square one and he'd have his mother breathing down his neck, telling him 'I told you so' whenever she got the chance.

Charlie sighed. He really thought Jack might be different from the other guy's he'd been with but he supposed that he was destined to chase away every guy he fell for. They all left him in the end for whatever reason. But he really thought Jack might be the one, despite all the warnings from his mother.

He sat on the edge of the large bath in the room and thought over everything he and Jack had been through together. Surely that was worth sticking together for? After all, why would Jack help Charlie overcome his agro-phobia only to leave him?

The Doctor had gone ahead to the console room to start the DNA scan, taking Jack with him to let Rose get a few minutes peace.

The first few readings were good. Jackie and Mickey were defiantly still alive. But where were they?

"Daddy, does Mummy have something in her tummy?" Jack piped up suddenly taking the Doctor by surprise who looked down at his son, who was sat on the floor at his feet.

"Yeah," the Doctor nodded bending down. "She's going to have another baby, so you'll have a little brother or sister."

"What about me?" Jack said his lip wobbling. The Doctor chuckled picking up his child.

"We still love you, Jack," the Doctor said tapping a few keys on the TARDIS. "Mummy's just going to have another baby is all. You're not going anywhere, don't panic."

"But the baby hurt Mummy," Jack said frowning at his Dad. "That's not very nice."

"The baby didn't mean to," the Doctor assured Jack. "It was trying to help but it went a bit wrong. You don't mind having a sibling do you?"

Jack shrugged.

"As long as you don't forget me," Jack said looking at the screen. His face lit up then. "Nana!"

The Doctor looked at the screen and noticed the Gallifreyan markings flying across the screen. He hadn't realised Jack could read Gallifreyan yet. But he was right. The TARDIS had located Jackie Tyler
