Disclaimer - I don't own Doctor Who, unfortunately. If I did then Romana, the Rani, Susan and the Meddling Monk would return.
SUMMARY - Instead of the Master, what would you say if instead of the end of the universe, the TARDIS brought the Doctor, Martha and Jack to the year 802,701 and found a different version of Yana ?
You Are Not Alone.
The TARDIS landed with a thud.
The Doctor looked around the console room with interest, landing in Cardiff and using the spacetime rift to refuel had been relatively fast especially since the rift had been unusually active. He only hoped nothing serious had happened.
Then Jack had appeared, running directly towards the TARDIS. It should've been expected, the Doctor thought. As a time agent Jack would have access to a Vortex manipulator, a rather nasty and primitive form of time travel.
The Doctor hadn't seen Jack Harkness in over 45 years since the Dalek emperor in the year 200.100, but he'd known what Rose had done when she took the time vortex inside herself.
Bit stupid of her really, he thought.
Rose had suggested returning to the game station to pick him back up when his last regeneration started to go wrong, not that he wasn't surprised. Vortex energy was more than simple radiation, like the kind his 3rd incarnation had suffered from and it did scramble up the brain a lot more.
The Doctor had refused, his regeneration had been bad enough, but to add in a fixed point in time….
It was unthinkable.
The Doctor hadn't been expecting Jack at Cardiff, but it did make a weird sort of sense. The TARDIS was dependent on energy scavenged from temporal rifts now the Eye of harmony was gone, destroyed by the Time war and himself.
The question was how long had Jack been at Cardiff waiting for him ?
As soon as Jack threw himself at the TARDIS, the timeship had thrown itself into a frenzy, shooting right into the far future with a speed that went right over the danger limitations. It reminded him vividly of the time in his 6th incarnation when he sent the Master and the Rani spinning beyond the galaxies in her TARDIS.
Fortunately, the Doctor was able to restore partial control using his sonic screwdriver and aimed it at the hyper drive, turning it off by shutting down the power supply.
Now, the TARDIS was on a planet in the year 802,701.
Ironic, the Doctor thought to himself, the TARDIS materialises in the same year as ol' Herbert George's time machine.
" Well, we've landed,"
Martha looked at him, eyes wide with wonder which was reflected in her voice, " So, what's out there ?"
The Doctor looked at the doors with a slight frown. " I dunno."
It was true. The TARDIS hadn't exactly been forthright with him and now he didn't know where they were.
Martha's voice took on a slightly teasing tone, " Say that again, that's rare."
The Doctor looked at her, deadly serious, " I mean it. The TARDIS didn't give me a chance to set the controls, now I dunno where and when we are. We could be anywhere in the universe and at any time."
Then he grinned at her childishly, trying to hide his slight apprehension. " Rather exciting, isn't it ?"
Jack Harkness woke up, and thought he'd just died and gone to heaven. In his vision was a beautiful dark skinned girl, outside his vision was a beautiful man with thick, messy dark brown hair, gazing down at him with a slight disdain.
" Captain Jack Harkness," he introduced himself to the girl, then he stroked her chin gently, " And who are you ?"
The girl giggled, a sexy sound, " Martha Jones."
" Nice to meet you Martha Jones."
The flirting stopped when the man said impatiently, " Oh, don't start."
Jack's tone was defensive, " I was only saying hello."
Martha looked at the man, " I don't mind."
Yep, definitely the Doctor.
