"you're leaving" Owen said flatly

"You're leaving" Owen said flatly

"Yes" Jack replied "now I want the four of you to sort out your differences and decide whose the leader…because if you all say Owen then I will worry"

"Oh thanks" Owen muttered

"You can't blame him" Melody said "he leaves you in charge one day and you rip the rift open"

"I was trying to save him" Owen protested

"I vote for Melody" Tosh said

"Melody" Ianto agreed

"What do none of you trust me?" Owen said

"No" everyone chorused

Owen sighed "fine Melody it is then" he mumbled "how long are you staying away for?"

Jack shrugged "no idea, could be ten minutes, could be a year, it's hard to tell when you're time travelling"

"They're on their way" Gwen said, in the distance the TARDIS could be heard. To everyone's horror the hand in the jar began to bubble.

"Come on then" Jack said "I can't wait to see Rose's face when she realises I am alive"

"Bye" the gang called as Gwen and Jack left. For some reason Jack picked up the hand in the jar as he walked out of the hub.

"Cardiff" the Doctor said happily

"Cardiff?" Martha repeated

"What's wrong with Cardiff?" Rose asked "it's not like we're stopping properly"

"We're not?" Martha asked

"Nah we're fuelling up and waiting for someone" Rose said

"Who?" Martha asked

"My sister, Gwen" Rose replied

"I forgot you had a sister" Martha said

"That means she hasn't been talking about me enough" came an amused voice from the door.

"Gwen!" Rose shouted running to a dark haired woman and pulling her into a long embrace.

"Oh Rose" Gwen said hugging her sister back "I missed you so much…Rose…?"

"Yes Gwen?"

"I can hear a double heart beat…"

Rose pulled away "ah" she said "long story, short version I'm not human"

"Gives you no excuse now Doctor" Gwen called over "good thing Mum isn't here, she would have had your head on a platter"

"Yes good to see you too Gwen" the Doctor said grinning "show her the ring Rose"

"Ring?"

Rose held out her hand to show the small yet simple engagement ring on her finger. Gwen squealed and pulled Rose into a hug.

"When did this happen?"

"1913 they lost their memories and were pretending to be human" Martha said

"Oh hello" Gwen said shaking Martha's hand "I'm Gwen Harkness Rose's sister, you must be the new companion"

"Martha, Martha Jones" Martha said smiling

"I got a surprise for you two" Gwen said turning to Rose and the Doctor "something that might give you a double heart attack"

The TARDIS door opened and Jack came in "so what have I missed folks" he said wrapping an arm round Gwen "I see you got a new member" he nodded to Martha "Captain Jack Harkness and you are?"

"Stop it" Gwen, Rose and the Doctor said instantly

"I was only saying hello" Jack pouted "you know full and well that I only have eyes for you Gwen"

The TARDIS shuddered and suddenly flung everyone across the room. Martha was clinging to the rail so tightly that her knuckled were beginning to turn white. Jack and Gwen were holding just a tightly to the rail as well.

"What's happening?" Jack shouted

"We're accelerating" Rose called back "one billion years"

"Five billion" the Doctor said "fifty billion"

"A trillion, five trillion, fifty trillion," Rose shouted her eyes growing wide. "A Hundred Trillion" Rose gasped.

The TARDIS shuddered before it stopped.

"Year Hundred Trillion" the Doctor said in awe

"What happens there?" Martha asked

"we're at the end of the universe" Rose said "out there…stars, suns, planets…all go…it's the end of time and space…" she shivered. "Everything dies"

"Sounds creepy" Gwen commented

"We could go…" the Doctor said "Barcelona, never managed to go we could go now"

"Or" Martha said "we can go and see outside looks like"

The five exchanged looks before running towards the door, everyone wrestling to get out first. In the end the five of them were on a heap laughing.

Then they looked up to see the barren wasteland and stopped.

"Whoa…" Martha breathed

"Well Toto we're not in Kansas anymore" Jack said

"Shall we explore?" Gwen asked

"Lets" Rose said

The five off them walked down the steep hill off to see what was left. As usual they ended up being chased by cannibals and ended up in a refugee place where a scientist was trying to make a rocket to utopia. The Doctor and Rose helped it move along and but something happened with the radiation and then Jack died from electric shock.

"You have a room that no man can enter without dying" the Doctor said to Professor Yana

"Why yes" Professor Yana said

Martha was trying to revive Jack when he suddenly woke up gasping for breath.

"Well I have a man that can not die" the Doctor said.

Both Martha and Rose looked like they were going to have heart attacks. Martha actually felt like she was going through a second one since she seen that hand in the jar.

"You knew I couldn't die" Jack said slowly when he was sorting out the radiation.

"Yes" the Doctor said flatly

"How long?"

"The moment I set eyes on you"

"Does Rose know?"

"No she's too new at being a Time Lord to know"

"What I don't understand is… I died Doctor. One minute I was standing in front of five daleks thinking of my wife, the next I wake up and the room is covered in dust. What happened?"

"What do you remember in between?"

"Darkness….then gold light and a sweet lullaby"

"Rose"

Rose almost spoke when she heard her name, thinking that the Doctor was calling for her.

"Rose?" Jack said slowly "I thought you sent her and Gwen home"

"Rose came back. She looked into the heart of the TARDIS and no one was supposed to do that…a Time Lord would have become a vengeful God…but Rose….she brought you back"

Rose closed her eyes, she could almost remember it, and the lullaby was strong in her head.

"I could have travelled with you sooner" Jack said "it was Christmas, the day you lost your hand…I found Gwen standing there by the wall…drunk…I could off…but Torchwood one was nearby…I couldn't risk it"

Gwen was fuming, the dream that she had was not a dream? Martha took one look at the two sisters' faces and knew instantly that Jack and the Doctor were going to be spending a century at least on the couch. Martha tuned out of the conversation and turned to the Professor Yana who was staring at something in his hand.

"Are you ok Professor?" she asked

"What? No…those drums in my head are playing up again….ignore me dear I am just a silly old man" he chuckled "nothing worked for me, even my watch never opened" he showed Martha the silver fob watch in his hands.

Martha's eyes widened "haven't you tried opening it?" she asked "I got to go and tell the Doctor something, be back in a moment"

She ran as fast as she could to tell the Doctor.

Professor Yana opened the watch.

Something hard hit both Rose and Gwen in the head.

Everything went black.

Rose came to and found herself lying on the TARDIS floor with Gwen curled up against her side.

"HELLO!" a male's voice shouted "oh hello, new voice, anyway Doctor, got to go, sights to see, tell Magic Jack and Soppy Martha goodbye for me. Don't worry about the sisters I have them here"

"DOCTOR!" Rose shouted, she ran to the door and began to bang on it

"ROSE" the Doctor shouted

She tried to open the door but it wouldn't open, she pushed with all her might "you know if I had a sonic screwdriver I wouldn't be in this mess" she said

"Rose this isn't the time nor place to talk about screwdrivers" the Doctor said

"GOOOOOOOOOODBYE" the young man said playing with the levers, the TARDIS engines began to move.

"What are you doing?" she shouted "who are you?"

"I am the Master" he said "and you and me and Gwen over there are going to have sooooooooo much fun"
