Nippy bows and disappears.

"I think you may have preyed upon that elf's commitment to the safety of your stupidly named institution."

"The presence in Hogwarts of a portal to another world which will otherwise have to stay open for the next two days while an owl reaches my father is absolutely a security concern."

"Your magic owls aren't even particularly quick, huh."

"They're - owl-paced."

"Owls are not even overland distance fliers ducks would make more sense why owls."

"Maybe there's a mention in a history book somewhere, it's not on my N.E.W.T.s -"

"He's a kind of incurious person."

"That's not fair at all."

"If it were just you you wouldn't even know about electricity not working in Hogwarts."

"To be entirely fair I'm not curious about the owls because owls are interesting or useful, I am curious because they are bizarre, and they probably seem normal to you."

"I think it's not ducks because that'd be less dignified. I bet at some point it was a class thing and then even once everyone was doing it it still had enough of the class-thing feel to it that no one wanted to deviate for practicality."

"Not a bad guess."

"Could be."

"He's from 2179 and there are three different magic systems involved and time freezes when you close the door so close the door we're going to learn everything they knew by 2179 and then I assume Timothy's planning to take over the world."

"- Niblet, can you grab my things -"

The elf vanishes - "Timothy was planning to do that anyway. Are those books from 2179 -"

"Cam, my father, Finis. Father -"

"Nice to meet you," he says distractedly, pulling Minor and eight books into his lap.

"...I'll just amuse myself till somebody has questions, I suppose."

"Do you have an explanation of things loosely tailored to where we're at, I assume the books won't be -"

"Not prepped, no, and I'm not up on your context because my world lacks wizards and I never studied nineteenth century history and even if I had I have spent the last several years participating in a war with an alternate universe version of you against an evil god on a non-Earth."

"...okay. I - really really want to read these books but I guess we should - start with that, actually - uh - go on -"

"Which bit?"

"...gods, alternate universe versions of people, wars, non-Earth -"
