Why Is Something Like That...

Heading for the continent once more, the children have realized that something happened to Luna on the island. Chako scans Luna and discovers nanomachines in her bloodstream, which were the reason for her quick healing. She scans the rest of the children as well, but only Adam has them too, which explains why Luna and Adam are able to communicate, why Luna could hear the mysterious voice, and why she could open the door to the ruins. Luna is extremely concerned that she has nanomachines, but tries to behave as normal in front of the other children. However, they can tell that it's just an act, and after three days, they plan a cheer-up-Luna surprise party.
