Doctor: Every now and then a little victim's spared. Because she smiled. Because he's got freckles. Because they begged. And that's how you live with yourself. That's how you slaughter millions. Because once in a while, on a whim, if the Wind's in the right direction... you happen to be kind.

Margaret (Slitheen): Only a killer would know that. Is that right? From what I've seen, your funny little happy-go-lucky life leaves devastation in its wake. Always moving on because you dare not go back. Playing with so many people's lives, you might as well be a god.
