Sophie's only reply is an extra-loud stomp over the floor of the castle as she heads towards her own small room to put on some clothing.

She's furious at Howl, but she's just as furious at herself. What a fool you are, Sophie! she tells herself bitterly, but she doesn't know quite what she feels the most foolish about: going on a mission without any sort of plan; starting a serious fight with the person she loves; or believing for a minute that Howl might see her as a partner instead of, at best, an endearing little liability.

Whatever is the greatest piece of foolishness, it's without question the last that stings the most.
