So I'd highly recommend you reacquaint yourself with the chapter on antidotes. I'll tell you more about bezoars in our next class. Right, up you go. Alys, don't forget your rat tail.
[The class disperses. Slughorn turns as Harry walks in.]
Aha! If it isn't the prince of potions himself. To what do I owe this pleasure?
Sir, I wondered if I might ask you something.
Ask away, dear boy, ask away.
Well, you see, the other day I was in the library in the restricted section and I came across something rather odd about a very rare piece of magic.
Yes? And what was this rare piece of magic?
Well, I don't know, I can't remember the name exactly. But it just got me wondering. Are there some kinds of magic you're not allowed to teach us?
I'm the potions master, Harry, I think your question'd better be posed to Professor Snape.
Yes, umm, he and I don't exactly see eye to eye, sir. What I mean to say, is, well, he's not like you. He might misunderstand.
Yes. There can be no light without the dark, and so it is with magic. Myself, I've always strived to live within the light. I suggest you do the same.
Is that what you told Tom Riddle, sir, when he came asking questions?
[He leaves the classroom. Harry knocks on Slughorn's door.]
Yes? Oh, it's you Potter. I'm sorry, I'm busy at the moment.
[Slughorn closes the door and locks it.]
