Professor Snape is here at school with us. [...] Sirius here played a trick on him which nearly killed him, a trick which involved me –"
Sirius's idea of justice could use some adjustment. It's really interesting that he says essentially the same thing about Snape as he later does about Peter. He has nothing but contempt for people who "sneak" around and try to cause problems for others.

"See here, Snape, be reasonable," said Fudge. "This door's been locked, we just saw –"
It's fitting that Snape gets a taste of his own medicine here. He's usually horribly unfair to everyone else, so it's fitting that he gets to experience an unfair situation too, where he basically gets screwed over.

Black and Lupin were looking at each other. Then, with one movement, they lowered their wands.
Harry's phrasing here is very interesting. He refers to Azkaban as "that place," implying that it's truly awful. But he decides that Peter really does deserve it, even if no one else really does.
