What's next?

They've both had a malfunction

Clara felt behind her with one hand. She found the skin of her backside, surrounded by ragged cotton. Looking down at the floor she saw where the seat of her panties had snagged and been torn free, leaving the word "Thursday" still stuck down there.

"Whoops." Amy giggled. "Maybe we can find you something to wear soon, you're going to catch a cold like that." she turned away.

"You should watch out for unexpected breezes yourself." Clara giggled.

"What?" Amy reached to the seat of her jeans and found them split open wide, revealing white lace. "Oh, shoot."

"I hope you're not catching my bad luck." Clara said.

"I hope not." Amy agreed, looking down at her clothing nervously, as if working out how many wardrobe malfunctions would leave her as exposed as her new friend. "Erm, I think that robot might be down this way, there's a generator or something, and it seems to be feeding on power."

"Lead the way." Clara said.

"Okay, but no staring at my bum."

"I think I'm still much worse off than you."

"True." Amy led Clara through the building, which turned out to be some sort of abandoned factory. "You know, it could be worse. When I first went travelling with the Doctor, I was only wearing my nightie."

"Are we talking Victorian-style thick cotton, or something small and lacy?"

"Thick cotton. But that didn't help much the first time we ran into Daleks and one of them snagged the hem on its... not wheels, whatever they move around on. Pulled the whole thing off me. And I don't know about you, but I don't tend to wear my underwear under a nightie."

"Did many people see you?"

"About a hundred Daleks. They seemed to find a human body fascinating. Here, it's just around this corner." Amy stopped by a large piece of machinery, and Clara stood next to her while the redhead peeked around. "Yeah, I think it's... quick, get back!"

She pushed Clara deeper into cover, following her into a narrow gap between that machinery and another one. There was another noise of fabric tearing.
