"I'll either make the rest of my body like yours or put it back once there are regular people."

"My thing has side effects. Although I guess if you haven't noticed 'em yet maybe the leg isn't gonna getcha."

"What kind of side effects?"

"Three days unfathomable agony, unquenchable thirst for human blood..."

"Goodness."

"Yeah. But your leg does not appear to be making with the unfathomable agony so probably you're good."

"It feels maybe a bit off but quite fathomably so at present."  She stands up and succeeds in putting weight on it without flinching.  "Were you evading the question about where you're from on purpose or did something distract you."

"Oh, I'm from Germany, but that was a long time ago, and almost certainly irrelevant to anything you actually want to know."

"Where is Germany.  And what would I actually want to know."

"Well, it's not like all Germans are vampires or all vampires are German and my being a vampire is much more interesting. Germany is in Europe kinda in between France and Poland. But I am increasingly confident that none of the languages you speak are from the right planet."

"I don't recognize any of yours either."

"It's very exciting! I don't quite know how I got here, I was not able to get back after I landed and even if there was a trick to it that's kaput now."

"How do you mean?"

"Your thing where you can tell what someone's like? I have that now and it's instead, not too. So I no longer have the thing that sent me here, but eh, no huge loss, probably, since it seems likely to be some kind of defensive power that shooed me real hard rather than an actual power the bearer had to teleport."

Apparently this warrants some more staring, during which the expansion of her brainspace pauses.  "Oh, I see, you have - two - and this language doesn't have the words . . ."

"A tragic deficiency. I do speak a lot of languages if one of them suits you better. I'll have picked up yours after a few days listening to people speak it, but not so much out here."

"This is fine, I - can pick up languages decently well at the moment, it's only that I would have expected them all to have words for such a basic thing and so I assume it's not basic to you."

"It's not! It's new and exciting! I didn't have it ten minutes ago."

"I do wish you'd kept what it replaced long enough for me to get a copy."

"It wasn't a very good teleportation power but it was one. Alas. Too late now. I should've stolen one of his toes."

"I'd offer one of mine but perhaps that can wait until there's someone around for me to copy a replacement from without the apparent risk of terrible side effects."

"That's very kind of you but your toe will not have a teleportation power."

"Well no, but if I understand correctly it would let you have my current specific version of the copying power again after you'd taken somebody else's.  Or a non-copying power.  Though I think we would have noticed if any of those were around."

"That's true, is there a lot of difference between versions of the power?"

"Oh, certainly.  Some of them are fast enough to just turn you into a duplicate of the person you're copying; some are slow enough that they take a while to have any noticeable effects."
