When Katarina reads "Little Red Riding Hood" to Agnes, she reads the version where the wolf eats the little girl. No happy ending. This whole episode is pretty bad. Several have mentioned Elizabeth's lack of oversight, even after the constant turning of the tables by Reddington (it's not always what it seems). She should be super suspicious but moves right into bed with the wolf. That whole Fleurs du Mal thing with the game is right out of Shirley Jackson and "The Lottery." By the way, that glass must have been really thin that gun would shatter it. It really is a case where the writers came up with the game and thought it would be fun.
