Vex's second question caught him off guard momentarily, his eyes opening as he responded, "Was...was that a joke?" He asked, clearly mocking her a bit, "You must have really warmed up to me. I should try to sleep on Cattians more often. No offense!" He added. To actually answer her question he merely stated, "I'm a learner. I love cultures, I love history and I love languages. I just love to connect with people."
Miriko mentioned the reason behind her personal skills, shifting the focus back to her as he listened, "So you're a merchant? Do you own a boutique somewhere?" He questioned, genuinely curious as to how merchants functioned in Fiore. Obviously it was currency for objects but some of his people exchanged favors or bartered for what they need when money was low. He had no idea how to operate an actual shop.
Her riddle seemed simple enough, he heard it and within a moment or two responded, "Is it the time of day?" before smiling cleverly hoping he was right.
