So, as much as I love this one artistically, I have a problem with it. It’s established that Neville’s best subject is Herbology (JKR has said that Neville becomes Herbology teacher at Hogwarts), though this doesn’t actually really become settled until Goblet of Fire or so. So, it is possible that Neville’s skill at Herbology was late-blooming, and he could have met his end in the Devil’s Snare under the trapdoor. It is far more likely, however, that he would have been beaten to death by a bishop on the chess board or just died of starvation in the room with the keys, but we’ll never know.
