DOCTOR: Good, good. Now, I'll need one minute to get clear. Get back! I told you this was life insurance. I've adapted the device to explode by remote control.

DOCTOR: All I have to do is squeeze my sonic screwdriver and boom, boom, Davros.

DAVROS: You need not elaborate, Doctor.

DOCTOR: Just so long as you've got it clear.
