Hikari watched, looking overjoyed at the fact she managed to get them to split on their own! She readied a fight in case the one that didn't appear to be the one who had control tried to attack. She swam down the the blue tear-shaped Gem (something told her it was a Lapis Lazulli...wonder where that came from.) and waited.
Garnet and Amethyst were both amazed at the fact Hikari had peacefully convinced Lapis and Jasper to un-fuse. They readied for an attack however.
