"You need your Inner Eye tested, if you ask me," said Ron, and they both had to stifle their laughs as Professor Trelawney gazed in their direction. (6.1.85)
Azkaban has lots of drama and excitement, but it also features lots of little scenes between friends, where they're laughing together or sharing a fun moment.

"It's all Malfoy's fault,, Hagrid!" said Hermione earnestly.
"We're witnesses," said Harry. [...] "We'll tell Dumbledore what really happened."
"Yeah, don't worry Hagrid, we'll back you up," said Ron.
Tears leaked out of the crinkled corners of Hagrid's beetle-black eyes. He grabbed both Harry and Ron and pulled them into a bone-breaking hug. (6.2.95-98)
Even while supporting Hagrid, we can see the unique personalities of each member of the trio coming through here – Hermione is earnest, Harry is decisive, and Ron is reassuring.
Quote #6
Crabbe and Goyle laughed openly, watching Neville sweat as he stirred his potion feverishly. Hermione was muttering instructions to him out of the corner of her mouth, so that Snape wouldn't see. (7.1.53)
Neville doesn't play a huge role in this book, but his friendship with Hermione is a long-standing thing (since the first book, really) so it's nice to see a scene where she's got his back.
