I mean, if I can do the potion properly from now on. It's only been once. In the real Potioneering Guild they make aspiring Potioners brew certain things more than once before they'll declare someone has the mastery over that particular brew. For Wolfsbane it's three proper cauldrons, I looked it up. So he probably means to test me on it for at least the next two months just to make certain I can uphold the standard. And I mean, it's really, really important that Mr Lupin's potion be right, especially with little Bea in the house and Ms Tonks and all. So once he's sure I can do it, then he can move on to the other potions he needs to work on, you know, like the cure for the Sleepers and more experimental things like that.
