Thanks for your comments, although it's not meant as a retelling of Cast Away, I just used a volleyball and Wilson as a pop-culture reference/joke that those who had seen the movie would get. I guess I could have used "Spalding" or "Dunlop" instead but Wilson has the best ring to it. The point here is that the castaway accepts the fate of arriving on the island (we also (intentionally) don't know the back story of how the person ended up adrift) and over time makes the island home and becomes one of its guardians. (I also intended to use the volleyball net as a decorative/decor resource that the castaway incorporates over time in the cave.)
It always remains a disappointment to me when I can't add music, believe me!
