Quote #1
CORNELIUS FUDGE: Oh! Albus... I see you got our notice about the time change of the hearing...
DUMBLEDORE: I must have missed it; but by a happy mistake, I arrived at the Ministry three hours early.
Cute move, Fudge. The Minister of Magic tried to change the time of Harry's trial to keep Dumbledore from showing up. It didn't work, but it's just a little reminder that Fudge has the power to make Harry and Dumbledore's lives very difficult.

HARRY POTTER: Sirius, what are you doing here? If somebody sees you...
SIRIUS BLACK: I had to see you off, didn't I? What's life without a little risk?
This is a pretty risky move. Sirius is showing up at Platform 9 ¾ where he could be recognized and hauled back to Azkaban. But Sirius has been so powerless for so long that he's just gotta seize a little bit of that control back by breaking the rules.

DOLORES UMBRIDGE: The Ministry of Magic has always considered the education of young witches and wizards to be of vital importance. Although each headmaster has brought something new to this historic school progress for the sake of progress must be discouraged. Let us preserve what must be preserved, perfect what can be perfected, and prune practices that ought to be prohibited.
Professor Umbridge's speech may be all passive-aggressive and flowery, but her meaning is pretty clear. The Ministry wants control of Hogwarts and now they've sent their henchwoman to do the job.
