Harry Potter and the Prisoner of Azkaban
How we cite our quotes:

Hermione gasped in a petrified whisper; Ron, however, spoke to Black.

Hermione and Ron's actions in this scene speak volumes about their friendship with Harry and about their own characters. Hermione, scared as she is, helps yank Harry back from danger while Ron, despite the pain he's in, manages to speak up boldly to Black.
