Well, this is definitely a different Harry (the contempt part?). While I can understand Harry getting a bit put out with Ron going on about the Slytherins. But after taking Ron to task for ranting, off Harry goes on one of his own. Poor Hermione, you'd think Harry, after sticking up for Neville because its the right thing to do and having experienced a lack of friends himself, would be more understanding and sympathetic with her. I though Pim was supposed to be a good influence on him???
