If I had the displeasure of introducing Dolores Umbridge to a crowd, it might go something like this:
Ladies and gentlemen, I give you Dolores Umbridge, the most hated headmistress in the history of Hogwarts.
Or, Dolores Umbridge, the wicked witch of the Ministry of the Magic.
But I think I would most like to introduce her in the words of George Weasley: Dolores Umbridge, the old bat.
Yes, that would give me pleasure.
As readers we, of course, side with Harry and all his friends. And we root against their opposition. And Dolores is definitely the opposition. I hope Harry gets to be an auror, especially after her display in the career counseling session. Talk about your micro-managers. Oh, and good for McGonagall standing up to the boss.
Harry's talk with Sirius and Lupin should calm him down about his dad. Their insistence on resuming his Occlumency lessons was revealing. Everyone believes this is serious business, but they won't tell Harry exactly why. Tell the boy already. Don't you know by now that this approach doesn't work with Harry. He will just go off in another direction if he doesn't understand why.
And then there's Snape. He needs to grow up and forget the past. Move on. Let it go. And just take one for the Order.
