"There's no such thing as the Doctor. I'm just a bloke in a box, telling stories. And I didn't come here because I'm ashamed. A bit of shame never hurt anyone. I came because you're sick and you asked. And because sometimes, on a good day, if I try very hard, I'm not some old Time Lord who ran away. I'm the Doctor."
"I sometimes wonder why I like the people of this miserable planet so much. The Silurians and Sea Devils are noble races. They have skills and talents you pathetic humans can only dream about."
