Rincewind momentarily forgotten, a smile hurting his heart, Xel reaches up--not to try and grab the leaf out of the air, but only to brush its rim in return. The air around him is glowing faintly gold.
Xel sighs right in his ear and takes his feet off the ground so he won't be kicked while shadowing Rincewind or cause timing problems when Rincewind (as Xel rather expects he will) speeds up again. Grasping the bony wrists, he holds them firmly behind Rincewind in approved ninja fashion, determined to wait through the probable initial reaction until Rincewind discovers the smoother quality and improved ability to concentrate on the area around him, with the distracting movements at his peripheral vision, for himself.
