Question: In Divination class, Harry predicts that Ron will suffer but be happy. Is this a particular reference to anything that happens later in the series? (I have read the books, so spoilers are fine).
Question: Do the dementors have personalities and souls? I thought they didn't, but in one chapter (I can't remember which at the moment), someone says that the Dementors "wanted to help."
Question: Could Professor Snape really get away with putting Neville's toad in danger (when he feeds Neville's potion to the toad at the end of class, saying that it might poison the animal)? I know that he is already a unfriendly teacher, but it seems that there would be some sort of rule against killing an animal that belongs to a student, and parents of other students might be outraged if they heard about it.
