Cass was incredibly grateful when Draken slowly transformed back to his old form, the one he was familiar with, and took control of the magic lesson again. Instead of explaining principles again, he actually got around to showing Cass what he could do.
It was simple stuff, as if Draken was following along with the beginner book that Cass had read. Unlike with the book, he actually got to witness Draken doing the moves and speaking the words.
Draken's moves were practised, elegant, and showed that he had a deep understanding of magic. One Cass shouldn't have been as surprised about as he was. He had to police his face, because Lord Blackburn would not have been surprised by this. This was a full Cass emotion, and he didn't need a visit from Lord Blackburn to tell him that.
It was…nice, actually, to learn that Draken wasn't just all brawn, but had an intelligence to him. He was still reckless, and a dragon, but he had a delicate part to himself. Layers. The man had layers.
