I was revisiting Rowling (and Yudkowski) and it occurred to me that the professors teach Defense Against the Dark Arts in the first six Harry Potter books all had hidden identities… except for Dolores Umbridge maybe?
Quirrinus Quirrel: Hiding part of Tom Riddle's soul, which had occasion to come out and play.
Gilderoy Lockhart: Hiding the fact that he was a fraud, a myth, with little actual skill in defense against the dark arts.
Remus Lupin: Hiding the fact that he was a werewolf.
Alastor "Mad-Eye" Moody: Is hiding the fact that he is really Bartemius "Barty" Crouch, Jr. in disguise, who has kidnapped the real Mad-Eye.
Dolores Umbridge: ??? After leaving the position she makes attempts to hide her status as having one Muggle parent, but I don't know if that fits.
Severus Snape: Hiding the fact that he is a triple agent, by pretending to be a double agent giving the pretense of spying on Dumbledore and Potter for Tom Riddle.
Two questions:
Does Dolores Umbridge break this pattern? She's certainly a hypocrite in many ways, but just just comes off as vile and sadistic, more than hiding her identity while the Defense against the Dark Arts Professor.
Has Rowling written or spoken anything about the nature of the Defense Against the Dark Arts professorship or its curse pertaining to individuals with hidden identities? Did she intend "hidden identity" as a literary conceit for all the professors of the cursed position?
