"You shouldn't." Kate briefly glances at Malcolm before focusing on Martin again. Why isn't he saying anything? He knows what his father is. Either way she does not like where this conversation is headed but she has an idea.

"We don't move in the same circles, Doctor Whitly." Kate uses the same form of address that Malcolm does. She does this because she is not about to call him Martin. "But perhaps we could chat on the way back to ADI? That's where you two are headed, right?" Certainly a serial killer wouldn't kill out in the open, she thinks. It would be best to get him to a place where there are people who could do something about him.
