Yeah, it really does seem like they knew it then and that's why they made Harry and Hydra and Malfoy stay here over the hols. D'you reckon Malfoy would've been such a goblin about it if he'd known his parents thought he might get paralysed if he went home?

But what I don't get is why they let everyone else go home then. If they knew, why were they still telling everyone it's just a muggle disease and magical people could never get it, why would they tell all those lies and let all the other kids leave the school? I mean, you or Stretton or loads of other people could probably have brought it back with you, and then Malfoy still might've got it. It's just daft!
