"But Howl turned to Sophie just then. "Grey doesn't really suit you," he said. "I thought that when I first saw you."
"Calcifer’s gone," Sophie said. "I had to break your contract."
Howl looked a little sad, but he said, "We were both hoping you would. Neither of us wanted to end up like the Witch and Miss Angorian. Would you call your hair ginger?"
"Red gold," Sophie said."
