“There you are then,” said Michael. “The day Howl forgets to do that will be the day I believe he’s really in love, and not before.”
Fast forward Chapter 21:
Sophie saw another person leap through the gap behind it. This one had flying black sleeves. It was Howl…

His eyes were so red-rimmed and his black sleeves were torn in several pieces. There was not much to choose between Howl and the scarecrow.
