Hermione: Don't you understand how she must be feeling? Well, obviously she's feeling sad about Cedric, and therefore confused about liking Harry and guilty about kissing him. Conflicted because Umbridge is threatening to sack her mother from her job at the Ministry and frightened of failing her O.W.L.'s because she's so busy worrying about everything else.
Ron: One person couldn't feel all that. They'd explode!
