Amy starts seeing things

"Wait right here," said the Doctor. "I'm going to scout out the territory."

"Okay, Doctor," said Amy as she watched the Doctor run off into the distance.

All of a sudden, Amy felt funny. Something in her head felt weird but she could not tell what kind of weird it was. Could it have something to do with the lost nano-watch? Amy really couldn't say.

All she knew was that one moment she was standing in the middle of an underground corridor, waiting for the Doctor; the next, she was wandering down another corridor, searching for something.

She saw a gentleman in a formal suit who looked a little like actor Kevin Spacey. Then she saw a woman in a elegant gown who wore a pearl necklace. Next she saw a little red-headed girl twirling around like a ballerina, which reminded her for some reason of her younger self.

Or an animated tree that kept saying "Groot" over and over again. Or a woman who had two antennae on her head like an insect. Or a green-faced girl who looked very familiar for some strange reason. Or a curly-haired guy who looked like someone Amy had once seen on an American sitcom. And then last but not least, she saw a blue-faced girl who took one look at Amy and said, "Look, guys! She's not wearing a nano-watch! She must be one of them!"
