They get horribly lost, and it takes them nearly an hour to find the middle, but oh, it's fun. Hermione even laughs, when Malfoy scrambles undignified up to the top of the hedge, then accidentally steps on a twisted branch that's too weak to support his weight – and falls straight into the hedge, requiring her to haul him out bodily. She giggles despite herself then, as she tries to pull him out of the hedge, half-hysterical little sounds she tries to stifle in the folds of her cloak, and when he collapses beside her his chest is shaking from quiet, wheezing laughter too.
