'It'd be brilliant!' the Doctor exclaimed.
The four of them were gathered around the TARDIS console with the three humans: Graham, Ryan and Yasmin looking at the slightly mad alien woman with confusion.
'Explain it to me again.' Graham said with a sigh of exasperation. 'Fully this time.'
'Right, so I've got this friend, Kate. She's head of UNIT,'
'UNIT?' Yasmin asked.
'Unified Intelligence Taskforce, they're part of the UN. Set up to deal with aliens on Earth.' 'Never hear of them,' said Ryan.
'You've don't even know who the prime minister is, of course, you're not going to know about some shadowy government organisation,' Graham said.
'Harriet Jones,' Ryan said defiantly with a sense of confidence, which received an outburst of laughter from Graham and Yasmin.
'Seriously? Mate watch the news once in a while,' Yasmin said, wiping a tear from her eye.
The Doctor patted Ryan on the back, 'Don't worry, I don't know either.' Somehow Ryan was exactly comforted by the notion that he was as out of touch with current events as a scatterbrained alien who travels through time and space.
'Anyway back to this idea?' said Graham.
'Oh yeah. Right, so Kate hasn't met me yet. Well, not this body, so I thought you could pretend to be me.'
'Okay. Why?'
'It'd be fun! She's not seen me as a woman yet, and I know you most of you humans are obsessed with the whole 'one sex for life' thing.' The Doctor said, fiddling with the controls on the brand new TARDIS console, casually ignoring the giggles that were coming from the two teenagers. 'And I've always wanted to have a disguise. My friend, well enemy they always wore lots of disguises. It looked fun.'
She liked the idea of being someone else. Until recently she was tired of even being the Doctor. Such a weight of responsibility on her shoulders and so ubiquitous around the universe. Once she had tried to delete her name from every database in the universe but soon realised that doing that for every database from the Big Bang to the end of the universe was far too much effort for her, so she decided to give up and went for ice cream instead.
The Doctor sidled up to Graham clasping her arms behind her and giving a long, expressive 'So?' Another sigh, 'Do I have a choice?'
'I mean you can say no...' but the Doctor had developed a forlorn expression with big puppy-dog eyes. It was an unexpected perk with this new body. In her new friends' time period mainly men (and some women) would obsess over her rather than the other way around like before. It was annoying but occasionally useful for getting what she wanted.
'Alright, fine. And her name's Kate?'
'Yeah. Kate Lethbridge-Stewart. Proper daddy's girl.'
