Harry sat there, white-faced and furious, staring at Uncle Vernon, hardly able to believe it. Aunt Marge coming for a weeklong visit ¡ª it was the worst birthday present the Dursleys had ever given him, including that pair of Uncle Vernon's old socks.
Harry was trying to remember page twelve of his book: A Charm to Cure Reluctant Reversers.

He walked away, leaving Harry feeling worse by far than he had at any point in Snape's office. Slowly, he and Ron mounted the marble staircase. As Harry passed the one-eyed witch, he remembered the Invisibility Cloak ¡ª it was still down there, but he didn't dare go and get it.
