Sirius Black: Fudge is using all his power, including his influence at the Daily Prophet, to smear anyone who claims the Dark Lord has returned.
Harry Potter: Why?
Remus Lupin: The Minister thinks Dumbledore's after his job.
Harry Potter: But that's insane! No one in their right mind could believe that Dumbledore...
Remus Lupin: Exactly the point. Fudge isn't in his right mind. It's been twisted and warped by fear. Now fear makes people do terrible things, Harry. The last time Voldemort gained power he almost destroyed everything we hold most dear. Now he's returned, and I'm afraid the Minister will do almost anything to avoid facing that terrifying truth.
