"So then, Martha Jones, Cappin Jack, where shall we go first?" she asked as they reached the console room and sped ahead of them, twirling round the console flicking switches, turning dials, before running to the typewriter. "I could take you to meet Lady Godiva. No that's boring! I know! How about..."
"Sorry Doc," cut in Jack. "But I need to get back to my team. At the least I need to clear up a few things with them. I sort of ran off on them before."
The Doctor stopped typing and looked at the floor for a moment. She had spent a whole year getting to know Jack again, and watched as he had been tortured, time and time again. Now she had to say goodbye.
"Ok. Setting co-ordinates to Cardiff." She typed at an impossibly fast speed. She grinned, as she took hold of the handbrake. "Here we go!" The TARDIS gave a lurch, throwing Martha and Jack of their feet, whilst the Doctor clung on, whooping and laughing. "Aaaaaaand laaaaaaanding!" The TARDIS settled with a bump and despite clinging onto the hand-break, she fell towards the floor anyway. But just before she hit the ground, Jack had stumbled forwards to catch her and pulled her up onto her feet in front of him. 'Uhoh,' thought the Doctor. 'I know that look in his eye'. She quickly turned around and pulled the hand-break down.
"Right then, we have arrived at our destination. Please leave in an orderly fashion!" she said.
Jack and Marta laughed and shook their heads, before walking down the gangplank and stepping outside. The Doctor looked around the TARDIS for a minute, before following them, making sure that she pulled the door closed behind her.
They said goodbye to Jack, but the Doctor knew that somehow, this would not be the last time she saw him. As she watched him walk towards a tourist information centre, still laughing in disbelief at the revelation of who Jack was, she knew that this was the right thing for him to do. During the last year, he had talked often of his team, wondering if they were even alive. It was clear that he loved them all, and needed to be with them. As Martha and she walked back to the TARDIS, she felt that she knew what was coming.
"Doctor? I think it's time for me to go home." said Martha once they had reached the console. The Doctor nodded and typed in the co-ordinates that would take Martha back to her family. "Travelling with you Doctor, it's been amazing, but my family needs me. I want you to take something though," she pulled out her phone and handed it to the Doctor. "If I call you on this, when I call you on this, you better come." She grinned at him, hoping that the Doctor would not take this as personal towards her. Perhaps before she had regenerated, part of the reason may have been her. She had done allot of thinking over the last year. She had loved him yes. But this new regeneration confused her, and she no longer felt the same. She loved her as a friend, yes. But she was no longer in love with her. As the Doctor pulled the handbrake, Martha was sent flying, but she had barley even noticed. She was too caught up in the look of sorrow in the Doctor's eyes. The eyes were different but the look was the same. She had seen that look allot, when the Doctor talked of Rose, of Gallifray, when she had first seen Jack, at the end of the universe. The infinite sadness and age that they contained could never be changed, and even when the Doctor was happy, her eyes would always hold the sorrow that was there.
They landed and Martha pulled the Doctor into a tight hug. "You take care. Ok?" she said, pulling away. "Just, just try to keep out of trouble." With one last smile she walked down the gangplank and through the doors, leaving the Doctor along in the TARDIS.
She looked around and sighed. She had hoped that after this regeneration, Martha would stay and travel with her. She placed the phone in a charging port and sat the co-ordinates to random. Now, it was time for adventure, and running. She had a new body and a new TARDIS, and nothing was going to stop her.
