Unnessisary Questions
If Sophie sometimes thinks that Howl is more of a prince than a wizard, she has a reason to. Perhaps he is not a true prince, born of a royal family, but he grew up like one.
If she had asked, he could have told her what little he knew about lower noble parents, land-owners in the mountain valleys, where the land is fertile and the people were simple. He could tell her of a quirky uncle known as a Wizard that he came to know very well later on in his life. He could have told her of his first time to court, and the near-golden glow that covered everything, especially that queen sitting in her throne.
Even a young boy, green in the ways of politics, could tell where everyone's eyes went when petitioning and socializing. And when he was presented to her and made his bow over her ring, he heard her voice as if at a distance, praising his parents.
He could tell her the pride at being chosen, when the messenger came and he said goodbye to his suddenly inadiquate life for the courts of the central city. There was not much to be told about the years of study, pleasure and comfort. They were full of magic, but the kind of magic found in books, rules and lines.
It was there, in those courts, that he learnt of the older boys who were cast by the wayside once they got older and the color of their hair faded, their eyes drifting away from their surrogate mother, and their interests turned to outside their cossoted lifestyle.
He wouldn't need to tell her that it was there and then that he knew that beauty was above everything, and even though he eventually left this woman who rejected his love with a laugh for another woman who loved him too much, this thought remained with him.
She understood how he had closed off his heart, after the death of his favored uncle, causing him to make the deal with Calcifer. She probably remembered it even better than he did; after all, she was the one who had torn down all of his barriers to reclaim his heart and promised to protect it.
He knows she will never ask all this, though, because she has always waited for him to speak first when it comes to the times before her. There are some black spots on his memory, entire days or weeks of nothing before finding himself exausted in bed. Her wisdom, so in contrast to her age, has always stunned him, and she knows that he only wants to cherish the time he has now with their new family.
