The birds were chirping and the sun was shining as TARDIS sat in front of Clara's house. All was calm and peaceful outside the great machine. Inside, however, was an entirely different matter.
"No, no, no!" The Doctor ranted as he paced around the center console.
"But Doctor," Clara protested, "if we don't take them along they'll tell their dad about the time traveling."
The Doctor skidded to a halt in front of his companion. Waving his hands about his head he spluttered, "Right, two kids will tell their dad that their nanny is a time traveler and the proof that they have are some pictures from online that may or may not be of her."
Clara bit the side of her lip and settled back on her heels. "Well." she said, with a hint of hesitation in her voice. "I guess if you put it that way. Alright." Clara ran to the door and opened it with the intention of telling off her two young charges. The second she even cracked open the door, though, she was nearly knocked over by the two kids busting their way into the TARDIS.
"Wow." The boy breathed. "It's bigger on the inside."
"Whatever." The girl replied. "I've seen it on TV. It's done with mirrors." The two children then raced off to explore with Clara close behind to make sure they did not fall into the pool.
The Doctor, meanwhile, just stood by the console his mouth opening and closing like a fish. The assembled hordes of Genghis Khan could not get through the TARDIS doors, but it seemed every other human could. He would have to work on that.
