Draco ripped out a piece of paper from an unknown book in the beginning of Chamber of Secrets. Hermione had a ripped out piece of paper talking about the Basilisk in the movie. Not sure I agree, but it's food for thought!
Book VII from Fred and George sucks. I sorta expected Dumbledore to Obi-Wan on us (that's the way Heroic quests flow), but Sirius and Dobby, I thought it couldn't get worse. Fred was the worst. - Harry Potter / Fred 'n George Weasley.
