The Doctor...is embarrassingly human for an alien.

I hope I won't become hated by geeks everywhere, but I don't really know comic books all that well.

It's a funny thing about stories. It doesn't feel like you make them up, more like you find them. You type and type and you know you haven't got it yet, because somewhere out there, there's that perfect thing -- the unexpected ending that was always going to happen. That place you've always been heading for, but never expected to go.

Have you met the French? My...GOD they know how to party!

Madame Kovarian: The anger of a good man is not a problem. Good men have too many rules. The Doctor: Good men don't need rules. Today is not the day to find out why I have so many.

The Doctor: I've seen bigger. Clara: Really? The Doctor: Are you joking? It's massive!

Sherlock Holmes becomes more human and more adept at fitting in with a lot of people, but he remains separate from the human race because he finds that a better place to observe that from. He stays on the mountain top because there, he can see clearly.
