Link sees her hesitancy, but he's patient. He doesn't push, or try to make her adjust faster. He just keeps things at a nice, easy pace.

But then she pushes him back, parries just right - and Link is pushed back. He doesn't need to tell her that, in a real battle, this is a moment she could take advantage of - a moment where she could strike.

Shu's smart. Link's sure she already knows. So instead he just gives her a little nod of approval - and keeps going. Now, he starts to push, and ramp up the difficulty a little.
