This is not a real chapter, and therefore is very short. This week was crazy for me.

Jack Harkness was alive. He knew that that wasn't possible: he had been hit by a Dalek, there was no coming back from that, not ever. He hoped this wasn't the afterlife, he really didn't want to spend the rest of time on Satellite Five. He stretched, got up and looked for the doors. He wondered what had happened to Rose and the Doctor, and if they'd survived the Dalek fleet. Jack was about to leave the hallway, when he heard the familiar wheezing sound that signaled the Doctor's arrival.

Sure enough, the large blue police box slowly materialized in front of him, and a young man in tweed and a bow tie stepped out. "Hello, Captain!"

Jack stepped up so he was right in front of him, and let his eyes travel up and down the man's body. Despite the professorish clothes, the man was very pretty. "Hello yourself," he said flirtatiously.

"Now's not the time, Jack, into the box!" Jack stepped in to find Rose leaning over the top balcony of a new, spacious, console room. The man from before started pushing buttons and pulling levers. "I'm sorry, girl, I feel it too, but we can't just leave him behind."

"Who are you?" Jack looked at him again. "Not that I care, mind you."

To his surprise, it was Rose who answered. "He's the Doctor."

"No, he's not."

The man in the bow tie looked up. "Yup! That's me - how do you like the new face?"

"That's…not possible."

"I regenerated. I'm surprised you haven't heard of it, honestly." He looked at Jack. "I thought you were taught about the Time War."

"We were only taught the basics. Time Lords v. Daleks, threatened all time, don't do that sort of thing. I thought the rest was legend."

The 'Doctor' stepped closer to him "You're a 51st century Time Agent turned con-man who left the Agency after they wiped two years of your memory. Rose and I rescued you after your 'perfect con' released nanogenes into World War II London. You were using the alias of 'Captain Jack Harkness.'"

Jack visibly relaxed. "I must say, Doc, I really though I was a dead man there."

The Doctor looked up sharply. "You were, Jack. You were dead."

"But I'm here now I…I thought I was hit by a Dalek death ray. How could I possibly be alive?"

"Rose brought you back." Jack turned to look at her.

"Don't look at me, he hasn't explained this to me either." Rose stood up and walked down,"I'm as confused as you are as to how you could be alive."

"Come, on Rose, you just missed me." Jack wiggled his eyebrows, and she laughed.

"Jack." The Doctor snapped his fingers in front of Jack's face. "Concentrate. I'm trying to explain things here. What do you remember last?"

"Daleks, everywhere. I was shot." He shrugged. "Then I woke up, and you appeared."

"Good. I was on time. Was a bit worried about getting that wrong, honestly, could have left you there for ages," the Doctor said, walking back around the console.

"Are your driving skills that bad? I could do better with my Vortex Manipulator."

"That thing is a piece of junk."

"No it's not. You're just jealous because you keep having to replace pieces."

"The TARDIS is one of the most sophisticated pieces of technology that exists in the universe today."

"That's just because there aren't any others left."

Rose stepped between them. "Stop fighting, boys. Now, Doctor, you were going to explain what happened to Jack?"

"After we left, I sent Rose back to the TARDIS, which sent her home, but she wouldn't stay there. She opened the heart of the TARDIS and absorbed it, then came back here and turned the Daleks to dust. I thought that was all she did, but I thought about it, and I realized that she would never have left you behind."

He wasn't sure why the Doctor was being so nervous and shifty. "So? I'm alive now."

"There's one more thing. When you were brought back, you were brought back for good."

"What do you mean?"

"You can't die."

Jack let this sink in. "How can I not be able to die."

"You're a fixed point in time; there's nothing that can take you out of the time stream, You shouldn't be able to exist."

"Shouldn't be able to exist?"

"You've studied basic mathematics, right?

"Of course."

"You're like an imaginary number made real; something not possible at all that has just walked up and said hello. It feels…unsettling, too, and it's making the TARDIS a bit scared."

"Can I still stay on, then?"

"Of course. She'll warm up to you eventually, but in the mean time, I'm going to let her take us where she wants to." He made a face. "That's basically what she does anyway."
