Disclaimer: How I wish I owned them! Anyway, I don't; they're the property of the BBC. Apart from Maxie.
It had been, until that point, a fairly normal sort of day. Maxie had got up, eaten breakfast (cereal, juice, tea), gone to school, stressed about forthcoming exams with her friends, and set off home again. That was when the day stopped being normal and became quite odd.
First of all the weather changed, abruptly and violently. Clouds rolled in, the wind suddenly picked up, and it began to rain. Maxie cursed, pulled her hood over her head, and started to walk faster. The streets were emptying as people sought cover, and she contemplated finding shelter in a shop - but she was already wet through, so there was little to be gained. She carried on walking.
Perhaps because she was more focused on missing puddles, Maxie succeeded in walking slap bang into the wooden wall of a large blue box that appeared to be standing in the middle of the pavement. She only had time to register the box's existence and wonder briefly what it was doing there before a door opened, and a man leapt out of the box.
"Show yourselves!" he called into the rain. Maxie turned from examining the box and examined the man instead; tall, thin, a rather cool long coat, and eyes currently glaring at the storm. "By the Treaty of Karkanuk," the man shouted, "I command you to show yourselves!"
Maxie began to back away from box and man both, certain that she had encountered a loony. Quite what the loony was doing in a blue box was beyond her, but given the weather it was worth getting out of there, and soonish.
But she found her road was blocked by something - something invisible, because no matter what she did she could not take another step. She tried putting out her hand, and that turned out to be a bad idea, because an electric shock caught her.
Maxie turned her attention back to the man from the box. He was now gesticulating wildly at a vague shape in front of him, talking at a million miles an hour, appearing from tone and gesture to be getting nowhere. He stuck a hand inside his suit, and pulled out a gadget glowing blue. Maxie watched, not really sure what she was seeing. There was a flurry of noise, of rain and thunder and lightning, and then the rain had stopped and the shape was gone.
She put out her hand again and felt nothing.
The man was tucking his gadget away again, and pulling out a key instead, walking towards the blue box.
"Hey!" said Maxie.
He stopped, and looked at her as though he was seeing her for the first time. "What?" he said.
"What?" she repeated. "What the … what was that?!"
"Nothing to worry about," the man said, breezily. "All gone. Shouldn't be back. Off you go."
"No," said Maxie, surprising herself. "That was weird. This -" she pointed at the blue box, "this is weird. And as for you …"
"Let me guess," he said. "Weird?"
"Yeah." Maxie stuck her hands in her pockets.
He did the same. "If you really want to know: I just averted an invasion of the Bibliosks. They won't be back. They like the electricity on this planet; feed off it, use it to grow and multiply. And now you're going to turn round and go back to school, and I'm going to leave. Goodbye." He waved at her, waggling his fingers.
"I'm on my way home," said Maxie, idiotically. "An invasion of the whats?"
"Bibliosks," said the man from the box.
"Right," she said. "And they're from another planet."
"Absolutely," he nodded. "Three thousand light years away. Remarkable race, really, but it doesn't give them carte blanche to waltz on to Earth." He stopped talking, and looked at Maxie, hard. She felt as if she was under a microscope, and fidgeted. "You look familiar."
Maxie pushed at her hair. "Do I? Never seen you before in my life. Whoever you are."
"I'm the Doctor," said the man. "Who are you?"
"Maxie Milligan," said Maxie.
He scratched his head. "Milligan … Milligan … why does that ring a bell?"
"Doctor what?" asked Maxie.
"Just the Doctor," said the man, cheerily, and as if it did not matter. "Never mind. Off you go, off home." He turned, and began to head towards the box again.
"That title has to be earned," Maxie said. "S'what my mum says, anyhow. Says you can't be a doctor just by saying you are."
The man - the Doctor - had stopped walking, and now he looked round at her. "I don't suppose … what's your mum called, Maxie Milligan?"
Maxie caught his eyes; there was something strangely intense about them. She thought about not answering, about turning and running, but changed her mind.
"Martha," she said.
The Doctor's face split in a grin, a grin full of joy and life and energy. "Oh, yes!" he said, taking a few quick steps towards her. Maxie backed away. "Martha Jones. Doctor Martha Jones. And you're her daughter!"
Maxie stared at him. "You know my mum?"
"Your mum saved the world," the Doctor said.
"Yeah, right," said Maxie. "She's saved a lot of people, but the world - not quite yet."
"She saved the world," the man said, something in his voice and his dark eyes that said he was utterly serious. "Saved the rest of your family too, as it happens."
"What, Grandma and Grandad and Aunt Tish and Uncle Leo?" asked Maxie, bewildered. "Well, I guess they're part of the world."
The man grinned at her again, flashing from serious to manic in a second, and grabbed her hand. "They are indeed! Maxie Milligan, you are going to show me where you live."
She tugged her hand back. "Hey! Wait a moment. First of all, no stranger touches me without my permission, right? Second, how do I know you really know my mum?"
He nodded. "Right. Quite right. All right." He put a hand in his pocket and pulled out a mobile phone - at least Maxie decided it had to be a phone, although it looked like a model from an old film. The Doctor flipped it open, pressed some buttons, and displayed the screen. It read "Martha Jones" followed by Maxie's mum's number.
"Oh," she said. "Okay, how do I know she'll want to see you?"
The Doctor considered that, and waved it away with a flick of his hands. "If she doesn't, she'll slap me." He frowned. "Actually, statistically speaking there's a very high probability that she'll slap me. Mothers tend to do that. I'll take the chance."
Maxie looked hard at him, and made her decision. "All right. This way." She set off, the Doctor keeping pace easily with his hands in his pockets. "So, because Mum's never once mentioned you, how did you meet her? You must have been pretty young."
He looked down at her. "In her hospital. When she was a medical student. It, erm, got taken to the moon."
"To the where?" asked Maxie, not sure she had heard him right.
The Doctor pointed upwards. "The moon. Small satellite rock orbiting Earth. Neutral territory, you see; nobody owns it."
She raised her eyebrows at him. "Right. The moon. Funny, you'd have thought Mum would have mentioned going to the moon."
"Oh, the moon's nothing!" said the Doctor. "Me and your mum, we went to New New York. We saw Shakespeare's lost play performed at the Globe Theatre. Visited the planet Raxacoricofallapatorius. Did a spot of shopping on Artemis. We saw the universe together."
"Right," said Maxie again, wondering exactly what her mother's reaction was going to be when she got home with the crazy guy she'd picked up outside a blue box.
