Dennett's about as easy to 'get' as a plump, very trusting fish.

"No, no! I, er, I haven't killed anyone yet." Something he's still strangely proud of, in a way. He's kept his doctorly 'first do no harm' intact.

"They say--they told me--if you find a place to hide, you don't have to." He's never quite managed that trick, and there are rats and...god knows what else down here so hiding is really unappealing-sounding.
