"Pond? She's, ahhhhhh. A quick-thinker. Spirited. Friendly. She'll have fallen in with someone by now, but there's no telling who. Someone interesting."
Possibly someone pleasant. Possibly someone dangerous. Definitely not someone cruel, unless they were very good at covering their tracks. The Doctor racked his brain. "Well. The Magic Box is a start. Pond's conspicuous. If they've seen her, they'll remember."
