This person is an odd mixture of knowledge and complete lack of it about Fitz. Fitz has been tested in various ways for large portions of his life.

He stays silent about that, however, letting Devin talk.

"I have my reasons for wishing the Fool well, and you are aware of some of those," he says in the end. "I have no reason to know why I should accept your authority, or why you wish to insult me quite so thoroughly before asking me to do so. I doubt very much that if I approached you with a similar attitude, that you would gladly fall under my command."

A short nod, and he hefts his small bag over his shoulder.

"Good day."
