Susan felt herself slipping into her teacher persona. This Doctor had more questions than a 7-year old on sugar cookies. She gestured at the city around them.
"People are apparently born her, live, die. But Grandfather doesn't come for them here, I'd know if he was around. So this must be a place that operates on a different system of some sort, because if Grandfather has taken another holiday and this was one of his places, I'd no doubt be called to take his place again. But people seem to die here without calling for either of us to make an appearance. So not someplace I've ever been before."
She nodded, "Well, generally everyone. Some are not on his list and of course Grandfather can't see them. But I generally can, because I'm part of both worlds, the supernatural and the normal."
Susan felt a slight tingle from the small glowing object Doctor held. "Device? No device, we just do. Oh, I sometimes use Grandfather's horse if I have a lot of luggage. Binky is such a dear that way. But time and space are easy, just are. Universes can be hard if Grandfather isn't believed in there, but as I said, I'm part of both worlds, so I go where I please."
"Your ship vanished or left you? Best to be precise in this situation. And beautiful? I've been called attractive in a sort of underfed way (she declined to call herself skinny as Ridcully had), but you'd think given who my grandfather is, I'd have had better cheekbones. But hardly beautiful. As I told you, my name is Susan Sto Helit, and if you must know, I do not choose to let the rules of mortality apply to me. Do try to keep up. Pointing out someone is not entirely human is hardly polite. I mean, I didn't make any comments about you now, did I Doctor?"
