Spoilers: Spoilers from the preview of the start of 'Utopia' – don't say I didn't warn ya! Spoilers are mild (see A/N below) – most of this prologue came from my own ideas before I saw the BBC preview. If you don't want to be spoiled even a little, check out the next chapter wherein Jack has just arrived on the TARDIS where the story becomes entirely non-canon and wanders off into my own little world! ;)

A/N Hello everyone! Seeing as I've finished writing (but not finished posting) my other chapter fic, 'Time to Heal' I started writing this story. This prologue is loosely based on the Jack and Doctor reunion that will take place at the start of 'Utopia'. I wrote the dialogue before I saw the BBC preview, so it's not going to strictly follow canon, apart form the bits about the location and Jack throwing himself at the TARDIS…

Anyway, I'm not sure where this story is going yet, but I hope you like it. I'll only write more if I get reviews so PLEASE press that little button – I love reviews!

Enjoy!

Prologue – Return to the Rift

"Where did you say we were going again?" Martha asked, holding onto the rails around the TARDIS console as the Doctor ran around pulling levers and twisting knobs with great enthusiasm.

"Cardiff!" said the man himself, cheerfully. "Didn't you hear me the first time?"

"Well yeah, but I thought – Cardiff?! He couldn't have said Cardiff!" Martha looked bemused.

"What's wrong with Cardiff?" The Doctor said, his eyes dangerous all of a sudden before brightening into a manic grin. "Lovely place! Right by the sea, the people are nice, very hospitable and they have a fantastic opera company!" He beamed.

Martha just shook her head at the absurdity of the Doctor. After travelling with him for a few months she thought she had cracked him but then he'd throw another bizarre spanner in the works and completely confuse her once more.

"A long while back me and R…" He began, still in full flow before stopping abruptly, his smile disappearing and his expression becoming dark.

Martha sighed. "Rose…" She muttered, turning her back to the Doctor. She was fed up of hearing that stupid name – Rose - whoever she was. Martha didn't like to admit it but she was insanely jealous of this mysterious 'friend' that the Doctor held so high in his estimations. She didn't want to admit it but she was falling in love with the strange alien who had shown her the universe, even though she increasingly realised that her feelings were not reciprocated.

The Doctor had stopped his wild dance around the console. He just stared into space, his mind consumed with memories of Rose, and suddenly their friend, Jack. The stupidly brave Jack Harkness who had given his life for them on Satellite Five. He remembered the time they had visited Cardiff together and met 'Margaret' The Slitheen. There were times when, in spite of himself, he missed the old team.

"Why exactly are we going to Cardiff, then?" Martha asked.

"We're not going…we're here." Said the Doctor, as the TARDIS landed with a bump. The enthusiasm had left his voice and Martha sighed in resignation, realising it was going to be 'one of those days' where the Doctor became completely insular.

"So, why are we here then?" She persisted, moving towards him as he pulled on his brown trench coat.

"The TARDIS needs fuel. There's this rift that runs through Cardiff and the TARDIS gets energy from it. Like a petrol pump for her." A hint of his smile returned and a bounce returned to his step as he moved to the door. "I open the engines and she soaks the energy up. So we'd better go find something to do – gonna be a few hours before we can leave again." He smiled at Martha.

She smiled weakly back and followed him up the ramp.

The Doctor opened the door and looked out on the courtyard of the Wales Millennium Centre, taking a moment to breathe in the sea air as he stepped out of his Time ship. Martha followed, standing beside him and looking around. She had to admit, it was pleasant. She had never been to Wales before, and having lived in London her whole life it was nice to be close to the sea.

The Doctor didn't make a move to whisk her off somewhere exciting, however. He just stood there. Martha watched him silently, his handsome features set into a painful expression. Memories assaulted the Doctor's mind…he saw Rose in the dungeon under the city, telling him that they would go down fighting, then he saw his previous incarnation bouncing away from the TARDIS with her hand held tightly in his own, closely followed by Captain Jack, all of them laughing and happy.

"I can't do this…" He said suddenly, turning on his heels and throwing the TARDIS door open.

"What? Doctor?" Martha asked, concerned as she followed him back into the blue box. "What the hell is wrong with you?!" She demanded as he set up the controls again.

"Nothing, I'm fine." He said, voice flat. "We're leaving."

"What about the petrol…" Martha began.

"Wait…" He said, looking quickly at his screen. "The rifts been active – should only take a few seconds! Brilliant!" He grinned. Then he looked at his viewing screen and saw a man he never thought he'd see again running flat out towards the TARDIS, his features contorted as he yelled his name.

'No…it can't be…' he thought 'I can't…he's going to ask…about Rose.' And with brutal force he hit the ignition lever.

Before Martha could protest any further she heard the familiar sound of the TARDIS engines revving up and grabbed hold of the nearest railing ready for take off whilst the Doctor heaved a sigh of relief at avoiding a painful reunion with Jack. There were just too many questions…

Just as the ship began to move there was a loud thudding sound against the door. The Doctor snapped out of his stupor.

"What the…" he began, rushing to the door as the TARDIS started her trip into the time vortex. He threw open the door, his eyes growing wide in horror. "Martha!! QUICK!" He yelled.

The young woman raced up the ramp behind him and helped the Doctor haul a body inside. He shut the door quickly and pulled the stranger fully into the control room. He was out cold.

"Doctor?" Martha asked, uncertainly, looking from the strange man sprawled on the TARDIS floor to the Time Lord. The Doctors eyes were wide and his face white as if he had just seen a ghost.

"Jack Harkness…you bloody idiot!" He muttered, dropping to his knees next to the other man before beginning to shake him roughly.
