Harry Potter and the Prisoner of Azkaban
How we cite our quotes:
"Goin' through a rough time at the moment. Bitten off more'n she can chew, if yeh ask me, all the work she's tryin' to do. Still found time to help me with Buckbeak's case, mind [...]" (14.1.38)
Hermione is once again most closely tied to the theme of time here and to the idea of trying to find more time. So it's fitting that, by the novel's end, she's confronted with the real limits of time.
"What? Oh no!" Hermione squeaked. "I forgot to go to Charms!"
"But how could you forget? said Harry. "You were with us till we were right outside the classroom!" (15.2.35-6)
Too bad Hermione didn't have an iCalendar with some alarms on it. It's interesting that this is one of the few times that Harry, rather than Ron, verbalizes Hermione's mysterious behavior.
"Only if we're more than fifty points up, Harry, or we win the match but lose the Cup. You've got that, haven't you? You must catch the Snitch only if we're – "
"I KNOW, OLIVER!" Harry yelled. (15.3.6-7)
The Quidditch final introduces another element of the time theme to us: timing. The Quidditch match served as a primer for the ultimate timing test: Harry and Hermione's down-to-the-second rescue of Buckbeak, their past selves (trippy!), and Sirius.
