Almost

Vernon just asked you for Polyjuice recipe. You understand why he choosed this one : it has a reputation to be tough to brew. But, too bad for him, the ingredient are actually simple. Some needs to be precisely harvested and all, that's the real trick. So, confidently, you list them : fluxweed, lacewing flies, leeches, knot grass, horn of bicorn, boomslang skin and the hair of the desired person. Vernon ask you if its your final answer ? Of course it is, maybe he is trying to make you change answer, but that's it.

"What about water ?"

You stop for a moment, looking at his stupid smile. You try to argue and all, but it is in the pot... even tho it's not mentionned on the recipe. And with the unbreakable vow spells, you cannot win this argument.

Frustrated and upset, you know have to answer to him for the next 7 days.

He tell you to meet him in his room tonight, after dinner before leaving in rush.
