Sybil Trelawney: 16 years I've lived and taught here! Hogwarts is my home! You can't do this!
Dolores Umbridge: Actually, I can.
[McGonagall arrives and tries to comfort Trelawney]
Dolores Umbridge: [to McGonagall] Something you'd like to say, dear?
Minerva McGonagall: Oh, there are several things I would like to say!
Albus Dumbledore: [Dumbledore arrives]
Albus Dumbledore: Professor McGonagall, might I ask you to escort Sybil back inside?
Minerva McGonagall: [to Trelawney] Sybil, dear, this way.
Sybil Trelawney: [shakes Dumbledore's hand] Oh, thank you! Thank you!
Dolores Umbridge: Dumbledore, may I remind you that under the terms of Educational Decree #23, as enacted by the Minister...
Albus Dumbledore: You have the right to dismiss my teachers. You do not, however, have the authority to banish them from the grounds. That power remains with the headmaster.
Dolores Umbridge: For now.
