Hmm, the polyjuice plan was a bit elaborate. But the main point of that was to get information, not to do something to Draco. (They were trying to get information that would prove he was the heir of slytherin and that would certainly have detrimental side effects, but the point is it was to gather information and not just out of malice.)

I was thinking later, though, that the werewolf plan wasn't really something Draco would do. He'd do something that elaborate, but I can't really see any one of the current kids doing something that dangerous. Snape was right to be really pissed and James was right to call it off. I know that the Hogwarts students risk their lives all the time on random things and so it's hard to say what's fantastical exaggeration and what's actual danger, but that was more than the usual.

sigh. I want the next book to come out. I only started all this speculation after the fifth book and so I've not had the experience of coming up with all these theories and then seeing what the author did next.

Though right now I'm going to be distracted by being sucked down into Lord of the Rings, again, as soon as I get ahold of the extended RotK. :)
