Harry looked at Hermione and she shrugged.  She'd usually wanted to stay snuggled up to Draco for as long as possible but Pansy seemed to have a different reaction.  It wasn't as if St. Mungo's had handed her a pamphlet with what to expect, and it could well be that the after-shock of the high was different for different people.  Harry drifted away, his eyes on Pansy until he shut the door behind him.  She didn't speak until they could hear his footsteps going up the stairs.
