You spy a boat on the shore of one of the islands below. You wonder who could be out here rowing in the middle of the ocean.
Author commentary: I'm not sure how John happened to find the island that Mom rowed to. Maybe it's his innate Roxy-detecting sense? Basically, much like the Sweet Bro Scrolls predict, any boy will have a preternatural disposition to seeking out and courting his bro's hot mom.
