"Are you a knight?"
Arthur nodded slightly, fearing a misunderstanding, he added a line: "That's right, not from Ireland, nor England, Scotland or Great Britain, but a knight of the United Kingdom."
The young lady seemed quite interested in this, she asked: "Is there any difference between them?"
It was a topic concerning heraldry, although Arthur's knowledge of heraldry was not deep, based on his historical literacy, he could respond quite easily.
Moreover, judging by this lady's ignorance on the distinction between titles, it was likely she was not of noble birth either, perhaps a banker or a merchant's daughter?
