Dolores Umbridge: What? Do something! Tell them I mean no harm!
Harry Potter: I'm sorry Professor. I must not tell lies.
Dolores Umbridge: You applied first for the defense against the dark arts post, I believe?
Professor Snape: Yes.
Dolores Umbridge: But you were unsuccessful?
Professor Snape: Obviously.
Dolores Umbridge: There is no need to talk for this.
Hermione Granger: No need to think is more like it.
Hermione Granger: This is Loony Love... Luna Lovegood.
Luna Lovegood: I'm hungry, I hope there's pudding.
Dolores Umbridge: Naughty children deserve to be punished.
Kingsley Shacklebolt: You may not like him, Minister, but you can't deny it, Dumbledore's got style.
Lord Voldemort: You're a fool, Harry Potter, and you will lose everything.
Hermione Granger: It's kind of exciting, isn't it? Breaking the rules.
Hermione Granger: At least we know one good thing that came out of today.
Harry Potter: What?
Hermione Granger: Cho coudn't keep her eyes off Harry. Could she?
Hermione Granger: He really is out there, isn't he? We've got to be able to defend ourselves. And if Umbridge refuses to teach us how, we need someone who will.
Hermione Granger: You've done it, Neville! You've found the Room of Requirement!
Ron Weasley: The what?
Hermione Granger: It's also known as the Come and Go Room. The Room of Requirement only appears when a person has real need of it, and is always equipped with the seeker's needs.
Ron Weasley: So, say you really needed a toilet...
Hermione Granger: Charming, Ronald. But yes, that is the general idea.
Harry Potter: It's brilliant! It's like Hogwarts wants us to fight back!
Answer: Draco is shocked because a teacher is never allowed to hit a student, not for any reason. He never expected Umbridge to behave in such a manner.
