Lord of Eagles
Yes, Ulrich had a pretty clear idea that Romulus' last question was rhetorical and was not meant for anyone aside from the king himself. However, if the lord of Adlerhorst was good in anything that did not involve politics or wielding a blade, it was answering rhetorical questions. Mostly to annoy people (who were in most cases equally annoying to him), but this time he just felt the need to answer to his king.
"My king, I will be completely honest with you. The words that you said in the last few minutes did not make any sense," he replied, returning back to his 'professional' self, "but I believe that it takes more than just a few moments to lose your sanity."
