Educational Decree Number Twenty-Four

- Chapter 17
OP17: Educational Decree Number Twenty-four

The High Inquisitor orders all Student Organizations, Societies, Teams, Groups, and Clubs disbanded, Harry and Ron learn that boys are not allowed in the girls’ dormitory, Hedwig is hurt coming back from London, and Sirius is almost caught by Umbridge in the Gryffindor common room fireplace.

Calendar and Dates

The entire chapter takes place over the course of one day, the Monday following the first Hogsmeade weekend (the first weekend in October).  Since 2 September was a Monday, this date has to be 7 October.

Interesting facts and notes

Neville's face was scarlet; the pressure Harry was exerting on his throat rendered him quite incomprehensible, but odd words spluttered from his mouth.

Exceptional character moments

Still to come.

Memorable lines

"Does this mean they're going to shut down the Gobstones club?" [Second year, upon seeing the decree]

"First of all, Ron - I've sworn to pass on a message from your mother. She says on no account whatsoever are you to take part in an illegal secret Defense Against the Dark Arts group. She says you'll be expelled for sure and your future will be ruined. She says there will be plenty of time to learn how to defend yourself later and that you are too young to be worring about that right now. She also" - Sirius's eyes turned to the other two - "advises Harry and Hermione not to proceed with the group, though she accepts that she has no authority over either of them and simply begs them to remember that she has their best interests at heart."
