"Count, are you loyal to His Majesty the King?"
"Of course I am loyal to His Majesty and the kingdom... What?! Are there rumors in the royal capital that I am planning to seize it?! How can there be such absurd and ridiculous nonsense?!! How could you believe such an absurd and comical thing?!!"
[Are the people in the capital out of their minds?] - Angry questioning might be a more plausible explanation, but sitting right in front of him is a baron from the capital. At this delicate moment, the Count is not going to speak out a conjecture that would offend all the residents of the capital under the royal family.
"There have been some rumors related to you, Count, spreading around the capital recently."
