I don't own Doctor Who.
A/N - Happy Christmas. This story has been in my mind for a short time now, where the Second Doctor chooses a female Third incarnation for his exile to Earth. Only she has no desire to stay behind for long.
The Third Doctor in this story, I see her being portrayed by Natalie Dormer.
The Diary of a Time Lady.
Scan for alien tech and a new body.
The last thing he had felt was the searing pain of regeneration, the fire of the renewal burning through his cells as his body was rebuilt and restructured on a cellular and temporal level. The last thing he felt was the first thing she felt.
She felt life while her body reformed and reshaped around him. As the regeneration had taken place, forced on to him by the Time Lords at the trial who had given him several choices for his next form who'd be exiled to Earth, the Doctor had dug in his heels foolishly hoping to browbeat the Time Lords presiding the trial to let him stay in the one body, but the Time Lords had quickly restored order while making it clear they were giving him a fair choice. And if he refused to take the trial and the choice of his new incarnation seriously...
Cowed into submission by the threats, the Doctor had given in and chosen a female incarnation. They had gone through the process once already, and it had been unpleasant to experience before and it was even worse now since it was being forced on them by the Time Lords. As the regeneration had taken place, his ideas were submerged as the new personality formed with new ideas taking hold until they formed while he had felt her hair growing and two breasts appearing on his chest which rapidly reformed into a feminine torso and his last thoughts as his body became female was regret that it had ended like this.
Her new thought was delight in her new life.
She emerged from the regeneration in a cocoon of golden energy, and she staggered on her brand new legs, blinking and slightly breathless. As she staggered around the console room, and she realised there had been a slight reduction in height, and the new weight on her chest had shifted her centre of gravity before she got used to her new footing and looked around. She was inside the TARDIS, his TARDIS…NO, her TARDIS. In his clothes and as she looked down at the rumpled and stained and battered frock coat and the tattered and threadbare check trousers, she fingered them sadly.
A strand of hair fell into her face. With a huff, she brushed it away…only to freeze and she grabbed the strands and saw that her new hair was blonde in colour, it wasn't short or black like she distantly remembered.
The Doctor looked around the console room frantically as the TARDIS started to materialise, and she checked the controls and looked the console over. Aside from the crack in the time rotor and the dents on the instrument panel, it looked alright, but a glance at the year meter made her grimace in disgust; why was it her previous self had never even bothered to fix the most simplest of the TARDIS instruments.
Her last body had been very remiss about the checks, but she had a feeling this new incarnation would be more rule-abiding on this level. Yes, they might have been on the move continually to avoid the Time Lords, but now the Time Lords had caught her, the Doctor actually found the lack of maintenance frustrating.
There was no telling where the TARDIS had landed; the Time Lords had claimed they'd exile her in the 20th century (unless of course, she was lucky enough to find a way out before she was here too long, despite the primitive technology here), but the 20th century had lasted for a long time. She hoped she was in the latter half where some of her contacts were, but she couldn't really recall their names although their faces were clear in her mind; a tall, neatly dressed man with an impeccably trimmed moustache wearing a military uniform, an old scientist with thick hair and a beard wearing glasses and a rumpled suit, and a pretty woman with short dark hair.
True, they would not recognise her in this body, but if she could persuade them then she might get the help she needed to get away from Earth.
But right now…
The Doctor turned uncertainly to the doors. There was nothing else for it, she realised she would need to leave. She glanced again at the console. The atmosphere was breathable, but she'd expected that - the Time Lords had taken control of the old girl while making sure that she behaved and didn't act up, after all.
She checked the scanner, but it didn't show anything that told her anything about the time zone. It was just a basic alleyway with brick walls. The Doctor sighed and she triggered the door control while making sure her key was safe. As she walked out of the ship, the Doctor winced as she caught the smell. She took a sniff to orientate herself, but her senses were still restoring after her regeneration.

The walkout of the alleyway did her the world of good. When the Doctor got to the street, she noticed the cars but she barely remembered the makes; she had seen so many cars on prior 20th century visits, but it was the number of soldiers walking around in full uniform with people carrying boxes on their backs that she got her first clues. The posters were another clue.
"World War 2," she muttered. She had enough sense not to say it aloud. The Doctor now knew the time frame, now all she needed to do was to look for something to tell her the date. Her eyes picked out a newspaper on the ground. The Doctor bent down and she picked it up. It was a slightly old edition. But she could see the date well enough. It read 1940. She was about to read more, but the way her jacket seemed to weigh her down caught her attention. The Doctor sighed and decided to head back for the TARDIS. If she was going to make a new life on Earth, especially during this point in history, then she needed to look the part.
The Doctor walked back to the TARDIS and she unlocked the door. She headed for the wardrobe. Down to habit, she walked over to the male section of the wardrobe before she remembered her slip. She headed over for the female section and looked through the collection. As she did the Doctor saw her new face. She had long blonde hair (that was new) with pronounced cheekbones, but what she liked the most was how young she was; her predecessor had been younger than her original incarnation, but only by a physical couple of decades. But now she seemed to resemble a woman in her early 20s. But it was hard to tell.
Time Lords were not meant to truly care about their appearances but she had learnt that many societies cared for their physical looks, but the Doctor quite liked what she looked like. She was younger than her predecessors were physically. And she liked the feeling. The Doctor turned her attention back to looking for clothes.

The Doctor walked back into the console room, wondering if her new clothes. She quite liked the black trousers and leather jacket, but what she truly liked was the union jack t-shirt. The Doctor was not sure about the outfit. Her predecessor hadn't really bothered with clothes much, but in her new body, they were much more important to her. True, it might not be appropriate to wear clothes like this, but she was content to experiment.
When she returned to the console room, the TARDIS console was beeping. The Doctor hurried over to the console and checked the readouts.
The TARDIS had been scanning for alien tech. The old girl had found three pieces of time travel technology in the city. As she scanned the readouts (privately the Doctor was starting to plan to install the scanner into the console; it was better seeing all of the information in one source than looking around everywhere) the Doctor identified a Chula warship which was tethered in Westminster, parked right outside Big Ben. There was a Chula 'ambulance' nano gene capsule close to the Thames, both pieces of Chula technology contained time drive technology but the final piece of technology was a vortex manipulator.
The Doctor stepped back, putting her hands in her pockets and rocking back and forth on her heels thoughtfully. She had no interest in the Chula ambulance although she was worried by its presence. She knew the vortex manipulator meant there could be a Time Agent nearby. She didn't want the Chula warship, either. But she did want the vortex manipulator. With one of those, she could restore the TARDIS to full working order.
Now all she needed to do was find out who this time traveller was, what he was doing, and find a way to steal his vortex manipulator.
