chapter 31-O.W.L.s and chapter 32- Out of the fire

OH MY GOSH! Ok so Harry's getting ready to take his last test. He finishes and falls asleep. He has this dream...Or more like vision about Voldemort torturing Sirius. Its awful! They're in the department of mystries and there's these glass spheres all around them. Harry runs to tell Ron and Hermione and asks how they're going to get there.
