Q considers for a moment before answering. "Now? No. Not possessed. But," he licks his lips, "I keep hearing him, his voice, his laugh. It's worst when I'm trying to sleep. And I can't help thinking, he's very clever, what better place to hide a part of himself than where he's supposed to be?" He touches his forehead. "Here. So you see, I've got to know. So I can be sure he's gone. Or he isn't."
"I know that," Q answers back. "But I'm not just going to nick the stuff from Severus' stores. I'm going to ask for it." Q nods. "That won't be a problem. Making amulets and such is a large part of defensive magic. I already have some protective ones."
"Oh yes," Q tells him, "but in the movie you could see it; her shrinking and wailing. It was actually pretty well done for something made seventy years ago. I just meant that's sort of what Polyjuice is like if you're watching it." Q blinks. "Oh goody," he comments dryly.
"Shame that," he smiles. "Let's see now," he consults his notes. "Peyote for dream induction about spirit animal. Make amulet to bind said spirit animal to me. Practice transfiguring one animal into another whilst retaining the mind of the first..." he taps his chin with his pen. "I get the feeling all of this is to discourage people from even trying it. By the way, where does one go to acquire a kitten? The pet shop doesn't have any."
*snort* He's actually a pretty good singer. According to JKR he was.
So noted. But Q sort of expects it from him and he really is scared that LV has left something behind and that he might be exposing people to GRAVE DANGER is he's found out. A trifle melodramatic, but he truly doesn't want anyone hurt.
