"Minor, can you go get an owl -"

"You go get an owl."

He makes another paper airplane instead, stands and holds the door and watches it fly off.

"Owls," mutters Cam.

"If you've got a fancy futuristic way of reaching my father I am sure he'd be delighted to receive a message from that instead."

"If you happen to know exactly how far away he or a place he'll look are, I can drop something there, but there would need to already be a thing. Can't pilot a drone if electricity doesn't work."

"I know where the house is, but probably not exactly enough - if you could make, like, a really good map -"

"The map would have to have already been mapped; can you name one of sufficient quality?"

"You can't do just a small version of the whole island - anyway, no, I don't know a sufficiently good map for that -"

"I can, but less magic parts. And we don't have room for one big enough to see a house."

"Owls it is, then."

Snort.

"What are you writing him do you even know all the things he'll need to know -"

"I'm sure I don't. I was planning to just tell him to come here."

"Could attach some doodad, if going through Hogwarts won't permanently break it, I don't know how plausible you can make the urgency."

"If we tell Dad come here right away he'll Apparate to the gates and then fly from there, that's not the problem - Timothy you could try to talk an Elf into taking a message -"

" -oooh, that's worth a shot -"

"These are the magical slaves?"

"Yes. - if you object we don't have to, but they won't mind -"

"I'm curious, actually, and I assume they won't stop being magical slaves if I don't look at them."

"I wish." Door open - "Hey, Nippy?" he says to the empty air.

Nippy materializes. "Mr. Timothy is wanting Nippy?"

"I need a really big favor, actually. We need my father right away to consult on something about Hogwarts security. Is there any way you can go to my house and get him, or call one of our family elves?"

Nippy furrows his brow. "Nippy can go and tell the family elves if it is for Hogwarts security, Mr. Timothy." Fervent nodding. "What is their names?"

"Niblet, Whimsy, Tipsy, Whoopsie and Daisy. Thank you very much."
