Their second to last exam, on Thursday morning, was Defense Against the Dark Arts. Professor Lupin had compiled the most unusual exam any of them had ever taken; a sort of obstacle course outside in the sun, where they had to wade across a deep paddling pool containing a Grindylow, cross a series of potholes full of Red Caps, squish their way across a patch of marsh while ignoring misleading directions from a Hinkypunk, then climb into an old trunk and battle with a new Boggart.
