Leonardo knows that asking his 'patron' Arcana for anything - answers, help, advice - is an absolute waste of time. In this particular chess game, he is playing Black, because the option Not To Play has already been taken off the metaphorical table. And so he sits directly on the sand, with his arms tucked around his knees, watching the ocean horizon languidly. He won't move or act or even imitate breathing until his patron does first.

And that might be 'til sunset, but hey... Leonardo's got all the time in the World.
