The Dentist:

"Hey, I know how to use a taser!" he said, putting down his taser, slowly backing away from the Ravecs. "You just gotta flip the switch and it turns on, then you just..." he made a swinging motion towards the Ravecs. "Zap it." he said as he followed the other two Timelords.

Ravecs:

The Ravecs creeped away from the Timelords and went up the stairs. They could see all of the city from the top of the tall building. They could see the people, they could see their dinner. They looked up to the moon and howled. Dinner was going to be served soon.
