People have probably talked about this before, but…
After rewatching Island Adventure, I had this thought. Do you think that Mask Island was Pink Diamond’s original attempt at making a Zoo?
The Zoo, from what we’ve seen, looks awfully similar to Mask Island. What reason would Mask Island have to exist for Gems anyway? Gems on Earth already had giant structures that were havens to them, such as the Lunar Sea Spire.
The other huge thing that made me think the island was originally a prototype for the Zoo is the only Gem we know of that was found there.
Was this a Gem that originally monitored the Island in case something went wrong with the humans, such as one trying to escape? If she had invisibility powers PRIOR to the Song of the Diamonds, it would make a lot of sense.
The lack of a proper exit (outside of a nice, long swim) and probably even forgetting the island in general could be a reason why this Gem was still there.
