Harry Potter and the Prisoner of Azkaban Scene 18

Scene 18

• Lupin brings Harry to his office, where he reveals he knows exactly what the Marauder's Map is.
• He chastises Harry for not turning it in.
• In the wrong hands, it could be a map leading directly to Harry.
• Lupin confiscates the map.
• Harry tells him that the map is on the fritz, like when Google Maps takes you the wrong way down a one-way street.
• Harry says it showed Peter Pettigrew, even though he is supposed to be dead.
• According to Lupin, that's impossible.
