Ravecs:
The Ravecs suddenly sprang up, and began charging towards the Timelords. They were hungry, and right infront of them was a pack of extremely tasty creatures, so they charged.

The Dentist:
The Dentist saw the Ravecs lurch up. "Uh, guys? I think we better start with the plan." he said, and then saw them start charging. "Run!" he shouted, and slightly pulled them as he ran towards the center of town, chuckling a bit under his breath. This was fun, the Doctor was right.
