The months between the Second and Third Tasks were... eventful, to say the least. It seemed like things were coming to a head; Mr. Crouch appeared on Hogwarts grounds, madder than Professor Moody before vanishing again. Then, there was the dream, the one where he was certain had actually been some kind of vision of Voldemort and Wormtail. Of course, accidentally using Dumbledore’s pensieve, a magical artifact that allowed one to store and watch memories gave Harry some insight into what happened to Barty Crouch Jr., which had left Harry with a lot more questions than answers.
