Chapter Four
We leave the ship called the TARDIS parked in an alley. It still looks like a blue police box, and I wonder if anyone who sees it would find it odd. I figure it's one of the Doctor's things, the ability to make a ridiculously obvious and out-of-its-time blue box seem perfectly normal.

The other three stroll down the street casually. Martha has her arm looped through the Doctor's, with the man called Captain Jack walking on her other side. They're laughing and joking and chatting about something or other and I follow silently in their wake. I'm too busy glancing around to care much.

I suppose the locals figure they're tourists or something--I dunno, were there tourists in these days?

But even this period must have its eccentrics. A lot of them, apparently, as we pass a group of people discusing... Philosophy? Why would anyone want to contemplate life? It usually makes my head feel like imploding.

I run a bit to catch up.

"So, what do you think?" the Doctor asks, falling back to walk next to me. He's got this huge grin on his face. I smile slightly, and it feels forced.

"It's... I don't know," I say honestly. "I mean, it really shouldn't be possible, but it is, and I'm not freaked out. I'm in the Italian Renaissance, and it isn't..."

"Isn't what?" He looks fairly concerned, but still smiling. I shrug.

"Not sure, really. I'll let you know when I figure it out."

He nods. "Take your time," he says with a surprising amount of patience. "For now, just enjoy yourself, okay?"

I shrug again, slightly, and offer him a small smile. This time, it doesn't feel as forced. "Okay," I say, and he grins.

"Good. Have fun, Katie. Just... Enjoy it. You're in the Renaissance. Not many people can say that!"

We catch up with Martha and the man called Captain Jack. I end up falling behind again.

Enjoy yourself...

I do make an effort. Honestly, I try. But I just can't find the same enthusiasm the Doctor has. And I don't understand why.
