They start walking

"I guess we should start walking then," said Missy.

"What about my clothes?" asked Clara.

"What about them?" said Missy.

"Shouldn't I bring them along just in case?"

"Don't worry, dear. I'll take care of them, " Missy said.

Missy pointed toward the west. "Anyway, you start walking in that direction. I'll catch up."

Clara shrugged and started walking, already regretting any action that encouraged her to turn her back on Missy.

Meanwhile, Missy had gathered up Clara's clothes and placed them in a pile. Then she got out her laser screwdriver and lit the pile on fire. She waited until the pile was nothing but ashes, and then walked off to follow Clara.

It would have been more fun to make Clara watch that just to see the expression on her face, Missy thought but she really had had no time for that. Not if she wanted to get to the Dalek city before dark.
