No: HPFGUIDX 26567 Forgive me if this has already been covered. In POA, Chapter 21, Harry and Hermione are told that Sirius is locked in Professor Flitwick's office. After rescueing him through the window of the office they then turn round and leave by the door (chapter 22). Have I misread something? In what sense is Sirius 'locked' in the office?
