Another thing you should know about the coming book (and my copy is on order):

Harry walks in as Ron is "forcing himself" on Hermione. Being a gentleman, Harry is torn between walking away from such a tender scene and helping Hermione but offending Ron (he doesn't consider helping Ron and offending Hermione). Instead, Harry performs a rather complicated spell and finishes by shouting "Kretuttok!" But instead of simply making Ron "soft" Harry also softens everything for 20 kilometers around -- Hogwarts itself is turned into a pile of semi-solid jelly. This makes it quite easy for The Dark Lord to take over and ensconce his minions in the White House and Number 10 Downing Street, to name but two places they become ensconced.

Harry, Ron, and Hermione are all that survive of Hogwarts and become a singing group doing, of course, soft rock.
