Harry Potter and the Prisoner of Azkaban
How we cite our quotes:
"If you're going to tell the story, get a move on, Remus," snarled Black, who was still watching Scabbers's every desperate move. "I've waited twelve years, I'm not going to wait much longer." (18.26)
Sirius's understandable lack of patience and his awareness of how many years he's lost are defining character traits.
"What we need," said Dumbledore slowly, and his light blue eyes moved from Harry to Hermione, "is more time." (21.80)
Once again, Hermione is most strongly identified with the idea of time here. We're surprised Dr. Who doesn't swoop in and try to reclaim his title at this point.
Hermione turned the hourglass three times.
The dark ward dissolved. Harry had the sensation that he was flying very fast, backward. A blur of colors and shapes rushed past him, his ears were pounding, he tried to yell but he couldn't hear his own voice –.
And then he felt solid ground beneath his feet, and everything came into focus again. (21.93-5).
The description of time travel is really fantastic here – there's a huge emphasis on sensory experience. We hear about sight, sound, and the crazy physical feelings that accompany time travel – it's like a super intense roller coaster ride. Done backwards. Props to Hermione for doing that a few times a day all freaking year.
