"What's it do?"

"Makes you look like someone else."

"Huh, okay. Assuming it's temporary even if it works on me like a human."

"Yeah, lasts an hour for humans."

"What determines who it turns one into?"

"Last ingredient is a hair of theirs. This is usually quite a constraint on who you can turn into but for you not so much."

"No kidding. Assuming it's working by, like, hair proteins, and not having-recently-been-on-someone's-head." Pause. "Requests?"

"Oh my. You're already kind of wearing my favorite face in the world."

"Thanks."

"I did not really bother developing celebrity crushes, it seemed kind of pointless and now I have higher standards anyway and am inordinately attached to wings and tail."

"Well, I have no other principled way to pick somebody. I guess I could turn into Miranda."

"I am sure she wouldn't mind. I am curious if people can turn into either kind of Elf and if so if they get the nifty Elf benefits but that's probably best a separate batch of testing."

"Yeah, since I will be actively trying not to turn into Miranda to see if I can."

"And it sometimes has weird effects on duration to aim for nonhumans and it'd be good to separate those from daeva effects on duration."

"Like if you try to turn into a house elf or something?"

"Yeah, or a centaur or a merperson."

"What happens to the duration? ..And what if one of them drinks it?"

"Can only partially transform, can be stuck that way until someone gets a counterspell, can just not last very long...I don't know what happens if they drink it."

"Seeing as I'm a nonhuman subject, do you know the counterspell."

"I do. Restorative potion, actually, and we have some on hand."

"Alrighty then. Do we also have polyjuice?"

"Yep!" He fetches it. It is bubbling and looks unappetizing.

"...Do I want to maybe go into this experiment with fewer tastebuds."

"If that's a thing you can conveniently do, yeah, it's not very tasty."

Cam presumably does... something... and then materializes a frizzy black hair. "I just drop it in? Or you do since I'm not a wizard?" He sounds a little slurred.
