Rose bit her lip thinking over what the Doctor could have meant in his message. She knew one thing for certain; she had to get to Bad Wolf bay. The parallel Doctor was watching her anxiously.

"Are you ok?" He asked. She nodded and opened her mouth to speak but the door next to her suddenly opened and a very bedraggled looking Pete Tyler stepped out.

"You've got a baby brother," he said, grinning almost as widely as the Doctor used to do. Rose smiled back, shooting the Doctor a 'just keep quiet' look.

Pete suddenly spotted the Doctor and did a double take. He glanced at Rose who looked guilty, knowing she should really have been thinking about her mother.

"Do you want to see him?" Pete turned to his daughter and decided to ignore the Doctor.

"Yeah," Rose stood up and followed her Dad into the delivery room.

Her Mum was lying looking very tired, but holding a beautiful baby boy. Rose sat next to Jackie Tyler on the bed and reached out to touch her brother.

"He's perfect," she grinned.

"He better be!" Jackie laughed, trying to sound annoyed. "You didn't take nearly this long when I was in labour with you."

"He was worth it though wasn't he?" Rose said cooing over the tiny baby in her mothers arms.

"Yeah," Jackie nodded. "We've decided to call him Rory."

"That's a fantastic name," Rose said still grinning widely. Then she remembered the Doctor sat outside and decided that it was now or never in telling them. Listen, I'm really sorry Mum, I'd love to stay, but work rang. I've got to take a business trip-"

"Now?" Jackie looked at Rose carefully. "Can't someone else go?"

"They need me," Rose said, hoping Jackie would put it down to her time travelling experience being needed. "I won't be gone long. I'll be back before you know it."

It wasn't entirely untruthful. The parallel Doctor's TARDIS would be able to get her to Norway and back in no time. Pete looked at his daughter with a 'how could you?' look.

"Where exactly are you going?" Jackie asked, glancing down at Rory.

"Cardiff," Rose lied quickly. "Something weird is happening with the rift, just standard protocol."

Jackie nodded and Rose backed out the room before her Dad could give her any more dirty looks. Mickey was awake when she stepped out and received more glares off him.

The Doctor looked up and Rose nodded at him. He stood up and stuffed his hands in his pockets.

"You're not seriously going off with him?" Mickey asked sounding almost like he was begging.

"I've got too," Rose said hoping that Mickey would understand. "I'll come back. I promise."

"You said that the first time you left," Mickey looked at his feet.

"Bye, Mickey," Rose said turning and wandering down the corridor, not looking back.

"He's just worried that you're going to leave him forever," the Doctor said quietly as they strode down the hospital hall.

"I know," Rose moaned.

"I suppose we're heading to Bad Wolf bay?" The Doctor asked after a few minutes of silence.

Rose nodded. They walked hurriedly, heads down against the cold as they headed back to Torchwood Tower and the TARDIS. When they reached Rose's office again she saw the files scattered on the floor and for once, was glad that she'd have something to tidy when she got back. Especially if she felt worse when she got back than when she left.

"I hope you know that I'm actually breaking several Time Laws to help you," the Doctor said smiling wryly.

"You never were one to abide by the rules," Rose said stepping into the TARDIS after him.

This TARDIS was different to the one her own Doctor had. The basic shape was the same but it was darker, blacker.

"It's a bit bleak in here isn't it?" Rose asked staring around as the Doctor set the coordinates.

"Never was one to abide by the rules," the Doctor grinned back, pulling a lever and setting the TARDIS into flight.

Rose laughed then; for the first time in months she actually felt happy. The Doctor grinned at her and looked so much like her own Doctor that Rose almost said something that she should have been saving for the parallel Doctor. But she caught herself in time.

The TARDIS jerked suddenly and the engines wined and wheezed as they came into land. The Doctor frowned, slightly confused.

"Something wrong?" Rose asked, noticing the worried look on the Doctor's face.

He must've realised that he looked anxious because he quickly rearranged his face and smiled at Rose.

"Nope, it's fine," he said, quickly shutting off the screen on the TARDIS before Rose could see the markings. Not that she could read ancient Gallifreyan anyway.

He wandered over to the doors and flung them open. He gestured for Rose to follow and the pair of them stepped out onto the cold windy beach of Bad Wolf bay.

It was totally deserted, bar the few scraggy rocks scattered around the sand. The Doctor walked forward a few steps and turned to Rose.

"I know what's going to happen," he said quietly, his eyes locking with hers. Rose frowned.

"What do you mean?" She asked.

"Just trust me on this one," the Doctor said, smiling slightly.

He walked around for a few minutes, Rose looking around for any sign of her parallel Doctor, but there was nothing.

"Right, it should be ready," the Doctor said heading back towards the TARDIS.

"What should be ready?" Rose asked following.

The Doctor didn't answer. When they stepped back inside the TARDIS Rose gasped. It was like the TARDIS the parallel Doctor owned had mashed with the TARDIS Rose had travelled in for all those months. But that wasn't the bit that made Rose grin and feel like bursting into tears.

Stood in the middle of the warped TARDIS was a dark skinned girl with black hair that stuck up all over the place and next to her, was Rose's Doctor.
