“Mermaid? Dragon? or were those just hypotheticals?” Markus didn't actually know how magical creatures presented themselves, and he certainly didn't see a tail instead of legs where Kai sat, though he was tempted to check again.
If he learned that dragons just looked like everyday people, he wasn't quite sure how he would feel about that. He knew Sunako and her brother had some strange bloodline. Trevelyan had revealed that he knew magic but didn't give any more beyond that.
