Duncan wasn't so lax as to laugh out loud in the middle of the fight, but his happiness, a physical, motion-bound pleasure, still sang in the twist of his torso and the impossible arch of his spine as he dodged both strange new attacks at startling speed. They were playing along! And still so fast, even after their session with Sheeana.

Their styles and techniques were often unlike many of the things he'd tried before, and that was why this was so valuable, so useful. A block became a jab and a kick became a throw, and he took his damage and dealt it. Saved the marveling for after, and tried still to keep an eye on Sheeana and Arha.

He improvised as he went along - had to - to adapt to Katara's unusual range and Tess's sharp instinct. This wasn't a teaching fight, not exactly, but he could (try to) pace it as one and ... maybe show off just a little bit.
