A year without any recharge? That is a very impressive power source. [For early 21st century humans, at least. Vastra doesn't know Pepper well enough to start raining on the parade with her 'I'm a lizard woman from the dawn of time, and we used to keep early humans as pets and space travel was routine' bit. That was at least fifth-meeting material.]

I suppose, given you are in charge of the business side, that you have answered these same questions over and over again. I hate to be dull.
