If there was one thing Kiwi knew, it was when she saw a mark. And there was nothing markier than a well-dressed man wandering through the slums of London dressed in fancy clothes. Even better, he looked as old as any man she'd ever seen, and he was a small one, at that. He could have held her up as high as his reach and no amount of bulging eyebrows could keep her from kicking him in the todger. Not even the burliest of grown-ups could stand up to that, 'cept for the women, but a quick tug on their neckline forced 'em to make a swift choice between their modesty and their purses.
Kiwi padded through the streets, blending in with the swathes of people, and changed up her pace as he moved around. He was gesturing this way and that, talking to some woman in strange clothes, and if she walked just right, slipped passed him, snatched into his pocket… Her hand came back with something slim and metal. She didn't know what it was, but it sat in her hand for a moment before a shudder suddenly went through her and it fell to the ground.
"Oh, I seem to have dropped my screwdriver." The stranger said, as he turned around, met her with a knowing gaze, then leaned down to pick it up. "Ah, nevermind. Just the decoy." He said, as he pulled another identical object from the opposite pocket. "You've got to be mindful of thieves around these parts, Ace. And you, little girl, I'm sure you know that as well as anyone, don't you, hmm?"
Kiwi got the feeling the man was mocking her, no matter how gentle his tone. But his grip was loose on both of them, like most people were when they were demonstrating. She nodded meekly, then snatched her hand out at the supposedly real device. It sat well in her hand.
"Hey, you give that back!" The girl, supposedly Ace, said to the little girl. Kiwi decided that she didn't like her.
"Now now, Ace, she's only a child. Why don't you tell me your name?" The man asked.
"Kiwi." Kiwi said, as she clutched the device for all it was worth.
"I'm The Doctor, and you have something of mine. What say you to a wager of sorts? You put that device on the line, and I'll wager a whole pouch of guineas." The Doctor offered, then reached into his pocket to retrieve a positively bulging coinpouch.
Kiwi was just a street rat, but she knew two things: Nobody wagered that much unless they wanted what you had, or they knew they'd win. So the device in her hand had to be worth more than it. So she wasn't going to let it go. She turned on her bare heel, then dashed into the crowd.
"Truly wonderful, the mind of a child." The Doctor sighed.
"You're just gonna let her get away?" Ace crossed her arms over her chest.
"I think so, for now. Perhaps if she were an elder god, I'd have a chance at getting it back, but I think I'll wait until she's older." The Doctor said.
