There was a magic time traveling box called the Tardis. In this magic box, there were three people, one alien called the Doctor, his two human companions Amy Pond and Rory Williams … and a little girl.

"Doctor," chimed Amy.

"Just one second, Pond," replied the Time Lord, busy tinkering with doodads and thingamajigs on his magic box.

"No, Doctor, there's someone –a little girl, actually –in the Tardis."

"That's highly impossible; no one can just get in my Tardis."

Rory, who had come to investigate what the Doctor was doing peered over the balcony and saw his wife standing across a small child of curly brown hair. "No, there is someone there, unless both mine and Amy's eyes are both deceived."

"It's quite possible," replied the Doctor,"It's called hallucination, sometimes stress related. Either that or you could be developing schizophrenia … rather a depressing situation, but completely human. Amy Pond and Rory Williams, I am sure you are human… unless you are some form of being that has managed to fool even the most advanced of alien technology. In which case –hello new race! –"

"Daddy," trilled a high soprano voice that belonged not to the Doctor, Rory or Amy. The Doctor jumped.
