Diane Claypool:
We have your friends surrounded. So, if you try anything, I will have them all killed. And then I will take the ear you have left and then your eyes and then your tongue. Do you understand?

Root:
You're too late. The machine's already talking. You're too old, older than 40. You can't hear a sound above 15 kilohertz. But I can... with the ear I've got left. My friend's been beeping morse code at that frequency since you brought your phone in here. She's been talking to me the whole time, telling me about you. You're scared of me, even with all these guards watching. By the way, that one has a bum knee. You're so scared of me that you hid a knife in your pocket. I couldn't reach it till you got close enough to cut me. [Removes her bonds, shows the knife] You still have a scalpel. I'd call that a fair fight.
