Ah... it was that, was it? He'd thought they'd exchanged, or something of the sort... but since she mentioned it, that made more sense. Still didn't stop a look of mild embarrassment from crossing his face, not realizing that that was the normal custom for such things. At least, for humans; for dragons like himself, he had to imagine this sort of thing was rather new.
"With me, you can certainly count on that much," Drace offered in assurance all the same. She was still... odd to him, just as any human perhaps might be... but he'd already sworn himself, after all. And besides, there were still curiosities that he'd not settled yet. Were anything to potentially happen, he would very much have something to say about it... and if he were to judge by Perseus earlier, it would surprise him if there was anyone larger than him in this kingdom.
To Joanna's reaction to his offer, though, the dragon's ears perked a little, curious what might've been going through the queen's head that she found amusing. When her question came, though, he couldn't help but smirk a little wider, this time giving her a slight, careful nudge with his elbow. "Really, you could ask me anything, and you ask me that? I'd thought the anatomy study would be for our next visit to that spot of yours in the forest in four days' time," he teased. "But as I've promised to answer... yes, it is fairly unique. My family, a sparse few other families; most of the rest just have scales, as you've seen. Many of them truthfully don't find the fur very appealing; they think it looks silly on us," he ultimately replied, allowing himself an idle, dismissive shrug. What they thought was their business; what he thought was that he was fine as he was.
"'Til it's time to go out there next, then... do feel free to request anything you like," he offered, turning his gaze curiously back out to the expanse that they could see from the balcony. "In fact, I might encourage it, at least from time to time. I am, admittedly, curious about more of what you're like. Let's say, you aren't... exactly what I'd expected from a human ruler. In a good way, that is," he offered with a little chuckle.
