I think Harry and Cho will finally hook up. He needs to stop feeling guilty for Cedric's death though, it was Lord Voldemorts fault, not his. Also, i think Hermione and Ron will hook up, in the books, the always flirt (bicker over dumb things) and in the movies,they hug, then lookat each other in a way of disgust. Malfoy and Parvati would be horrible.
